Step-by-step explanation:

We are given that in triangle RST, RS=65 and ST=60

We have to find the equation that could be used to find the value of angle S.

We know that

[tex]cos\theta=\frac{Base}{Hypotenuse}[/tex]

Base=ST=60 units

Hypotenuse=RS=65 units

[tex]\theta=S[/tex]

Substitute the values in the given formula

Then, we get

Step-by-step explanation:

The object reaches -200 degrees C at 15 hrs, coldest temperature it ever achieved

Answer:

The correct option is C.

Step-by-step explanation:

It is given that the temperature of the material in degrees Celsius, y, can be modeled by the following graph, where x represents the time, in hours.

From the given graph it is clear that  

1. The y-intercept is 40, so the initial temperature is 40 degree Celsius.

2.The vertex of the upward parabola is at (15,-200), so material's temperature reaches a minimum -200 degrees Celsius at 15 hours.

3. The material return to its initial temperature after 30 hours because the temperature is 40 degree Celsius at x=30.

Therefore the correct option is C.

Step-by-step explanation:

If we imagine this is on a clock, then point P is at the 9-o'clock position.  When we rotate it 90 degrees clockwise, that's a quarter rotation, so P' will be at the 12-o'clock position.  So the coordinates of P' will be (0, 5).

Answer:

5 inch

Step-by-step explanation:

The frames are proportional, so we can set the ratios equal:

width / height = width / height

3 / h = 9 / 15

9h = 45

h = 5

Given the proportionality between two pictures one with width 3 inches and another with dimensions 9 inches by 15 inches, we can set up a ratio and solve for the unknown length, yielding the length of the picture frame as 5 inches.

The question is asking to find the length of a picture frame, given that its width is 3 inches and that it has the same proportions as a picture that is 9 inches wide and 15 inches long. The proportions can be used to set up a ratio, as follows:

To solve for x, cross-multiply: 3 inches * 15 inches = 9 inches * x.

Then, divide by 9 to solve for x: 45 inches/9 = 5 inches.

So, the length of the picture frame whose width is 3 inches would be 5 inches, if it shares the same proportions as the 9 inch wide by 15 inch long picture.

Answer:

23%

Step-by-step explanation:

156 / 678 * 100 = 23%

The correct answer is 23%

Final answer:

Joshua brought about 23% of his LEGOs to Emily's house, which is calculated by dividing 156 (the number of LEGOs he brought) by 678 (the total number he owns) and then multiplying by 100.

Explanation:

To find what percentage of LEGOs Joshua brought to Emily's house, you divide the number of LEGOs Joshua brought by the total number of LEGOs he owns and then multiply the result by 100.

The formula to find the percentage is:

(Number of items of interest ÷ Total number of items) × 100 = Percentage

So in this case, it would be:

(156 ÷ 678) × 100

First, you perform the division:

156 ÷ 678 = 0.23 (rounded to two decimal places)

Then multiply by 100 to find the percentage:

0.23 × 100 = 23%

Therefore, Joshua brought about 23% of his LEGOs to Emily's house.

Step-by-step explanation:

One pair of corresponding angles (in the bottom left/right) are already marked for us, and we're also given a pair of corresponding sides (the 8cm ones on the left and right). The two triangles have one more angle in common too - the one they're overlapping on the top corner. So, we have:

- Two pairs of congruent corresponding angles, and

- A pair of congruent corresponding sides between them,

which is enough information to call the triangles congruent by Angle-Side-Angle (ASA).

To determine the number of small boxes and large boxes shipped, we can set up a system of equations and solve for the variables. In this case, we have two equations based on the total weight and the total number of boxes. By using the elimination method, we can find that 10 small boxes and 12 large boxes were shipped.

To solve this problem, we can set up a system of equations. Let's denote the number of small boxes as x and the number of large boxes as y. We can then write two equations based on the information given:

45x + 75y = 1350 (equation 1)   (since the total weight is 1350 pounds)

x + y = 22 (equation 2)   (since the total number of boxes is 22)

We can solve this system of equations by either substitution or elimination method. Let's use the elimination method. Multiply equation 2 by 45 to make the coefficients of x in both equations equal:

45x + 45y = 990 (equation 3)

Now, subtract equation 3 from equation 1:

45x + 75y - (45x + 45y) = 1350 - 990

30y = 360

y = 12

Substitute the value of y back into equation 2:

x + 12 = 22

x = 10

Therefore, the number of small boxes shipped is 10 and the number of large boxes shipped is 12.

Pam shipped 10 small boxes and 12 large boxes of paper.

Let's denote:

- x : Number of small boxes of paper.

- y : Number of large boxes of paper.

1. Total number of boxes shipped:

x + y = 22

2. Total weight of the shipment:

[tex]\[ 45x + 75y = 1350 \][/tex]

Now, let's solve these equations step-by-step.

Solve for  x + y = 22

From equation (1):

[tex]\[ x + y = 22 \]\[ y = 22 - x \][/tex]

Substitute  y = 22 - x  into equation (2)

Substitute  y = 22 - x  into equation (2):

[tex]\[ 45x + 75(22 - x) = 1350 \][/tex]

Expand and simplify:

[tex]\[ 45x + 1650 - 75x = 1350 \]\[ -30x + 1650 = 1350 \][/tex]

Solve for x

Subtract 1650 from both sides:

[tex]\[ -30x = 1350 - 1650 \]\[ -30x = -300 \][/tex]

Divide both sides by -30:

[tex]\[ x = \frac{-300}{-30} \]\[ x = 10 \][/tex]

Find y

Now that we have ( x = 10 ), substitute back into ( y = 22 - x ):

[tex]\[ y = 22 - 10 \]\[ y = 12 \][/tex]

- Number of small boxes: 10

- Number of large boxes: 12

Check the total weight:

[tex]\[ 45 \times 10 + 75 \times 12 = 450 + 900 = 1350 \text{ pounds} \][/tex]

This matches the given total weight of 1350 pounds, confirming that our solution is correct.

Answer:

acceleration

Step-by-step explanation:

In a speed-time graph, the speed data is on the Y-axis and the time is represented on the X-axis.

A slope is the variation of Y-values over the variation of the X-values between to points.

So, the slope of a speed-time graph would be the variation of the speed over the variation of time.

Let's say your units are m/s for the speed and s for the time.

The slope units would then be calculated by dividing m/s by s... (m/s) / s....

That would give you m/s², which is an acceleration unit.

Answer:

the answer is C 0.75 to 1.0

Over the intervals 0.25 to 0.5, 0.5 to 0.75, and 0.75 to 1.0, the exponential and linear functions are approximately equal.

To determine over which interval the exponential and linear functions are approximately the same, we first need to define the functions. Let's denote the exponential function as [tex]\( f(x) = e^x \)[/tex] and the linear function as ( g(x) = mx + c ), where ( m ) is the slope and ( c ) is the y-intercept.

Given the intervals, we'll first need to calculate the values of the exponential function at the endpoints of each interval and then find the linear function that best approximates those values. We'll choose the linear function with the same value at the starting point of each interval and approximate the slope ( m ) based on the difference in the exponential function values at the endpoints of the interval.

Let's start with each interval:

1. Interval from 0.25 to 0.5:

  - Endpoint 1:[tex]\( f(0.25) = e^{0.25} \approx 1.284 \)[/tex]

  - Endpoint 2: [tex]\( f(0.5) = e^{0.5} \approx 1.649 \)[/tex]

  - Approximating a linear function starting at ( f(0.25) ):

  [tex]- \( m = \frac{f(0.5) - f(0.25)}{0.5 - 0.25} = \frac{1.649 - 1.284}{0.5 - 0.25} \approx 0.73 \)[/tex]

[tex]- \( c = f(0.25) \approx 1.284 \)[/tex]

    - So, the linear function is [tex]\( g(x) \approx 0.73x + 1.284 \)[/tex]

2. Interval from 0.5 to 0.75:

  - Endpoint 1:[tex]\( f(0.5) = e^{0.5} \approx 1.649 \)[/tex]

  - Endpoint 2: [tex]\( f(0.75) = e^{0.75} \approx 2.117 \)[/tex]

  - Approximating a linear function starting at ( f(0.5) ):

  [tex]- \( m = \frac{f(0.75) - f(0.5)}{0.75 - 0.5} = \frac{2.117 - 1.649}{0.75 - 0.5} \approx 0.934 \)[/tex]

 [tex]- \( c = f(0.5) \approx 1.649 \)[/tex]

    - So, the linear function is [tex]\( g(x) \approx 0.934x + 1.649 \)[/tex]

3. Interval from 0.75 to 1.0:

  - Endpoint 1: [tex]\( f(0.75) = e^{0.75} \approx 2.117 \)[/tex]

  - Endpoint 2: [tex]\( f(1.0) = e^{1.0} \approx 2.718 \)[/tex]

  - Approximating a linear function starting at ( f(0.75) ):

 [tex]- \( m = \frac{f(1.0) - f(0.75)}{1.0 - 0.75} = \frac{2.718 - 2.117}{1.0 - 0.75} \approx 1.202 \)[/tex]

 [tex]- \( c = f(0.75) \approx 2.117 \)[/tex]

    - So, the linear function is [tex]\( g(x) \approx 1.202x + 2.117 \)[/tex]

4. Interval from 1.25 to 1.5:

  - Endpoint 1:[tex]\( f(1.25) = e^{1.25} \approx 3.490 \)[/tex]

  - Endpoint 2: [tex]\( f(1.5) = e^{1.5} \approx 4.482 \)[/tex]

  - Approximating a linear function starting at ( f(1.25) ):

   [tex]- \( m = \frac{f(1.5) - f(1.25)}{1.5 - 1.25} = \frac{4.482 - 3.490}{1.5 - 1.25} \approx 3.946 \)[/tex]

    - [tex]\( c = f(1.25) \approx 3.490 \)[/tex]

    - So, the linear function is[tex]\( g(x) \approx 3.946x + 3.490 \)[/tex]

Now, we can compare each linear approximation to the exponential function within its respective interval:

1. For the interval from 0.25 to 0.5, the linear function [tex]( g(x) \approx 0.73x + 1.284 \)[/tex] is approximately equal to the exponential function [tex]\( f(x) = e^x \).[/tex]

2. For the interval from 0.5 to 0.75, the linear function[tex]\( g(x) \approx 0.934x + 1.649 \)[/tex] is approximately equal to the exponential function [tex]\( f(x) = e^x \).[/tex]

3. For the interval from 0.75 to 1.0, the linear function [tex]\( g(x) \approx 1.202x + 2.117 \)[/tex] is approximately equal to the exponential function [tex]\( f(x) = e^x \).[/tex]

4. For the interval from 1.25 to 1.5, the linear function [tex]\( g(x) \approx 3.946x + 3.490 \)[/tex] is not approximately equal to the exponential function [tex]\( f(x) = e^x \).[/tex]

So, the exponential and linear functions are approximately the same over the intervals from 0.25 to 0.5, 0.5 to 0.75, and 0.75 to 1.0.

Answer:

i) 35

ii) 0.95

iii) employees’ annual earnings are strongly related to their tenure

iv) Employee earnings increase with tenure.

Step-by-step explanation:

i) The regression line for this data set has a slope close to m = 35

To find the slope of the regression line we need to find two points that lie on the line or that are very close to the line.

We have the following two points;

(1, 175) and (2.5, 225)

slope = (change in y) / (change in x)

         = (225-175)/(2.5-1) = 33.33

This is close to 35.

ii) The correlation coefficient is close to 0.95

The coefficient of correlation is a measure of the degree of association between two variables. Correlation coefficient gives information on the strength and direction of a linear association.

The scatter-plot reveals that the annual earnings and tenures of the employees of Stan & Earl Corp are strongly positively associated hence the correlation coefficient is close to 0.95.

iii) Based on this information, we can conclude that employees’ annual earnings are strongly related to their tenure.

The correlation coefficient was found to be close to 0.95. A value greater than 0.7 shows a strong degree of association between two variables. Therefore, employees’ annual earnings are strongly related to their tenure

iv) Employee earnings increase with tenure.

The slope of the regression line of the data set was found to be close to 35. A positive slope implies that the response variable increases with increase in the explanatory variable.

Nevertheless, the correlation coefficient was also found to be positive which suggests a positive association between employee earnings and tenure.

Answer:

The regression line for this data set has a slope close to m = (35) , and the correlation coefficient is close to (0.95) .

Based on this information, we can conclude that employees’ annual earnings are (strongly related) to their tenure. Employee earnings (increase with) tenure.

Answer:

Midpoint Formula is (x1+x2/2, y1+y2/2)

(-3+4/2, -5+4/2)

Midpoint is (1/2, -1/2)

Step-by-step explanation:

Answer:

Answer: The slope is 2. The y-intercept is 4 which means point (0, 4).

Step-by-step explanation:

First, find the slope of the line that passes through those two points using the slope formula.

[tex] slope = m = \dfrac{y_2 - y_1}{x_2 - x_1} [/tex]

where the points are [tex] (x_1, y_1) [/tex] and [tex] (x_2, y_2) [/tex]

[tex] slope = m = \dfrac{18 - 4}{7 - 0} = \dfrac{14}{7} = 2 [/tex]

The slope is 2.

One of the given points is (0, 4). Since the y-intercept lies on the y-axis, the x-coordinate of the y-intercept is 0. Point (0, 4) is the actual y-intercept.

Answer: The slope is 2. The y-intercept is 4, or point (0, 4).

To find the slope, use the S=(y2 - y1)/(x2 - x1) formula

S=(18-4)/(7-0)

S=14/7

S=2

After finding the slope, us the intercept formula to find the intercept

m is the slope

y-y1=m(x-x1)

y-4=2(x-0)

y=2x+4

Answer:

jina by .1 cm

Step-by-step explanation:

3/5 = .6

caleb = 23.6

jina = 23.7

Jina's model of the Empire State Building was taller by 0.1 centimeter compared to Caleb's model.

The question is comparing the heights of two models of the Empire State Building. Jina's model is 23.7 centimeters tall. Caleb's model is 23 3/5 centimeters tall, which in decimal form is equivalent to 23.6 centimeters tall. Therefore, Jina's model is taller. The height difference between Jina's model and Caleb's model is 23.7 - 23.6 = 0.1 centimeter. So, Jina's model is 0.1 centimeter taller than Caleb's model.

The answer is D

Let x = -2

f(-2) = 8 - 4(-2)

f(-2) = 8 + 8

f(-2) = 16

D is the answer.

If f(-2)=16 which could be the equation for f(x) f(x)=8-4x will yield f(-2)=16

A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.

Given

Let x = -2

f(-2) = 8 - 4(-2)

f(-2) = 8 + 8

f(-2) = 16

therefore, f(x)=8-4x will yield f(-2)=16
