Answer:

To find perimeter, you must add length plus length plus width plus width.

(L+L+W+W)

the length is 5, and the width is 8. since there are 4 sides, we must add 5+5+8+8, and that equals 26.

As we know the formula for finding the perimeter of a rectangle is:

[tex]Perimeter=2(L+B)[/tex]

here, L is the length of the rectangle and B is the breadth of the rectangle.

As the values of the length and breadth are given, we will put in the formula;

[tex]Perimeter=2(8+5)[/tex]

[tex]Perimeter=2(13)[/tex]

[tex]Perimeter=26[/tex]

Hence, the perimeter of the rectangle is 26 units.

Perimeter is the distance around the edge of a shape.

The total length of the boundary of a closed shape is called its perimeter. Hence, the perimeter of that shape is measured as the sum of all the sides. Thus, the perimeter formula is Perimeter(P) = Sum of all the sides.

Any equation expressed in terms of parameters is a parametric equation. The general equation of a straight line in slope-intercept form, y = mx + b, in which m and b are parameters, is an example of a parametric equation.

(A) - Hachi does not earn any money if he does not work

Step-by-step explanation:

If you think about it the graphed point is (0,0), so it is self explanatory that he works 0 hours and OBVIOUSLY he wont earn any money if he doesnt work.

The graph shows the amount of money Hachi earns at his job in relation to the number of hours he works. Hachi does not earn any money if he does not work.

A function is defined as a relation between the set of inputs having exactly one output each.

We can see that the graph linearly increases as the hour he worked and the money he earned will increase.

we know that the graphed point is (0,0),

He earned 10 money per hour of work.

so it is self-explanatory that he works 0 hours and obviously, he won't earn any money if he doesn't work.

To find the product of 3840 and 5 using an area model, we can draw a rectangle with a length of 3840 units and a width of 5 units. Then, we divide the rectangle into smaller squares or rectangles of equal size. The product of 3840 and 5 is 19,200.

Explanation:

To find the product of 3840 and 5 using an area model, we can draw a rectangle with a length of 3840 units and a width of 5 units. Then, we divide the rectangle into smaller squares or rectangles of equal size. For example, we can divide the rectangle into 384 squares of length 10 and width 5, or into 192 squares of length 20 and width 10. After that, we count the total number of squares to find the product. In this case, the product of 3840 and 5 is 19,200.

She is 4 years an d3 months old

Answer:

111 months

Step-by-step explanation:

First, look at how many whole years old Emma is. Emma is 9 whole years old. 1 year consists of 12 months. So, multiply 9 [years] by 12 [months] to get 108. The number 108 is how many months are in 9 years. However, Emma is 9 months and 1/4 years old.

To find out how many months 1/4 of a year is, multiply 1/4 [year] by 12 [months] . 12 is the same as 12/1, so multiply the numerators and denominators of 1/4 and 12/1

1 x 12 = 12

4 x 1 = 4

12/4 = 3

Therefore, 1/4 year is 3 months. Now, add 108 months and 3 months to get 111 months. Therefore, Emma is 111 months old.

Answer: (0.15,0.37)

Step-by-step explanation:

did the quiz

The range of possible values that best describes the estimate for the population parameter is [0.16, 0.38]. Therefore, the correct answer is option D.

Given that, a sample proportion is 0.26.

In statistics, the sample proportion is an estimate for the population parameter. When given a sample proportion, the range of possible values that best describes the estimate for the population parameter is typically the 95% confidence interval for the sample proportion. The 95% confidence interval states that if the same sampling procedure is repeated on many samples, then 95% of the confidence intervals constructed this way will contain the true population parameter.

The 95% confidence interval for a sample proportion is given by [p-1.96√(pq/n), p+ 1.96√(pq/n)], where p is the sample proportion, q is the complement of the sample proportion (q = 1 − p), and n is the sample size.

In this case, the sample proportion given is 0.26, and so p = 0.26, q = 0.74, and the sample size can be assumed to be large (n ≥ 30). Substituting these values into the 95% confidence interval equation yields the range of possible values that best describes the estimate for the population parameter: [0.16, 0.38].

Therefore, the correct answer is option D.

Area is the amount of space that a two-dimensional shape takes up. It is measured in square units, such as square feet (ft^2), square yards (yd^2), or square meters (m^2).

To calculate the area of a rectangle, multiply the length by the width.

Area of a rectangle = length * width

To calculate the area of a square, multiply the side length by itself.

Area of a square = side length * side length

To calculate the area of a triangle, multiply the base by the height and divide by 2.

Area of a triangle = base * height / 2

Perimeter is the total length of all the sides of a two-dimensional shape. It is measured in linear units, such as feet (ft), yards (yd), or meters (m).

To calculate the perimeter of a shape, add up the lengths of all the sides.

Perimeter of a shape = sum of the lengths of all the sides

Example:

To calculate the area and perimeter of the rectangle in question #4, we would use the following formulas:

Area = length * width = 5 yd * 72 yd = 360 yd^2

Answer:

the required equation is:

[tex]x^2 -10 +34[/tex]

Step-by-step explanation:

The equation given is:

[tex]x^2 -()+34[/tex]

Comparing it with standard quadratic equation

[tex]a^2 +bx+c[/tex]

a= 1,

b=?

C= 34

We can find the value of b using Vieta's formulas :

That states that if roots x₁ and x₂ are given then,

x₁ + x₂ = -b/a

We are given roots: 5 ± 3i i.e, x₁= 5 + 3i and x₂= 5 - 3i

solving

5 + 3i + 5 - 3i = -b/1

10 = -b

Since the given equation already gives b as -b so, -b= 10 => b=10

Putting value of b in the missing place the required equation will be:

[tex]x^2 -10 +34[/tex]

To find the missing term in a quadratic equation given complex roots, use the properties of conjugate roots to determine the term.

Since the roots are in the form of a complex number, they are conjugates of each other, which helps in finding the missing term.

Given roots: 5 ± 3i

Using the sum and product of roots formula

Sum: (5 + 3i) + (5 - 3i) = 10. Product: (5 + 3i)*(5 - 3i) = 34

Construct the equation: x2 - (10x) + 34 = 0

Answer:

[tex]sin(t) =\frac{\sqrt{7}}{4}[/tex]

Step-by-step explanation:

By definition we know that

[tex]sec(t) = \frac{1}{cos(t)}[/tex]

and

[tex]cos ^ 2(t) = 1-sin ^ 2(t)[/tex]

As [tex]sec(t) = -\frac{4}{3}[/tex]

Then

[tex]sec(t) = -\frac{4}{3}\\\\\frac{1}{cos(t)} =-\frac{4}{3}\\\\cos(t) = -\frac{3}{4}[/tex]

Now square both sides of the equation:

[tex]cos^2(t) = (-\frac{3}{4})^2[/tex]

[tex]cos^2(t) = \frac{9}{16}\\\\[/tex]

[tex]1-sin^2(t) =\frac{9}{16}\\\\sin^2(t) =1-\frac{9}{16}\\\\sin^2(t) =\frac{7}{16}\\\\sin(t) =\±\sqrt{\frac{7}{16}}[/tex]

In the second quadrant sin (t) is positive. Then we take the positive root

[tex]sin(t) =\sqrt{\frac{7}{16}}[/tex]

[tex]sin(t) =\frac{\sqrt{7}}{4}[/tex]

The value of sin(t) = √7/4 because sine is positive in Quadrant II.

First, recall that sec(t) is the reciprocal of cos(t):

sec(t) = 1/cos(t)

Given: sec(t) = -4/3, so:

cos(t) = -3/4

Since angle t lies in Quadrant II, cosine is negative, and sine is positive. Use the Pythagorean identity:

sin²(t) + cos²(t) = 1

Substitute cos(t):

sin²(t) + (-3/4)² = 1

sin²(t) + 9/16 = 1

Solve for sin²(t):

sin²(t) = 1 - 9/16

sin²(t) = 16/16 - 9/16

sin²(t) = 7/16

Take the square root of both sides:

sin(t) = √(7/16) = √7/4

Since we are in Quadrant II, sine is positive:

sin(t) = √7/4

Answer:

The ninth term is -0.75.

Step-by-step explanation:

Let's write the actual formula for this arith. seq.

It will have the general form a(n) = a(1) + (n-1)d, where a(1) is the first term, n is the term counter (1, 2, 3, .... ) and d is the common difference.

Here, a(n) = -2.75 + (n - 1)(0.25)

So the ninth term of this sequence is

a(9) = -2.75 + (9 - 1)(0.25

      = -2.75 + 8(0.25)

      = -2.75 + 2

       = -0.75

The ninth term is -0.75.

Answer:

[tex]a_9=-0.75[/tex]

Step-by-step explanation:

The given sequence has the first term, [tex]a_1=-2.75[/tex] and d=0.25

The general formula for an arithmetic sequence is given by;

[tex]a_n=a_1+d(n-1)[/tex]

Since we want to find [tex]a_9[/tex], it means n=9

We substitute the given values into the formula to obtain;

[tex]a_9=-2.75+0.25(9-1)[/tex]

[tex]a_9=-2.75+0.25(8)=-0.75[/tex]

Hence, the 9th term is

[tex]a_9=-0.75[/tex]

Answer:

The center of the circle is (-3 , 5) and the length of the radius is 9 units

Step-by-step explanation:

* Lets revise the standard form of the equation of the circle

- The center-radius form of the circle equation is in the format

 (x – h)² + (y – k)² = r², where the center is the point (h, k) and

 the radius is r.

- This form of the equation is helpful, because you can easily find

  the center and the radius.

* Now lets solve the problem

- The equation is (x + 3)² + (y - 5)² = 81

- By comparing the two equations

∵  (x – h)² + (y – k)² = r² and  (x + 3)² + (y - 5)² = 81

# x - h = x + 3

∴ -h = 3 ⇒ divide both sides by -1

∴ h = -3

# y - k = y - 5

∴ k = 5

# h and k are the coordinates of the center of the circle

∴ The center of the circle is (-3 , 5)

# r² = 81 ⇒ take √ for both sides

∴ r = 9

∴ The length of the radius = 9 units

* The center of the circle is (-3 , 5) and the length of the radius is 9 units

The center of the circle is at (-3, 5), and the radius of the circle is 9, determined by the given equation (x + 3)^2 + (y – 5)^2 = 81.

The student is asking about the equation of a circle and how to determine the coordinates of the center and the length of the radius. The given equation is (x + 3)2 + (y – 5)2 = 81. The general form of a circle's equation is (x - h)2 + (y - k)2 = r2, where (h, k) is the center and r is the radius.

To find the center of the circle, we look at the values h and k in the equation, which are the opposites of the constants added to x and y, respectively. Therefore, the center is at (-3, 5). To find the radius of the circle, we take the square root of the number on the right side of the equation. The square root of 81 is 9, so the radius is 9.

Answer:

h = 47.70 ft

The antenna is 47.70 ft tall.

Step-by-step explanation:

The height of the antenna is approximately 47.4ft when calculated using the Pythagorean theorem: √((50ft)^2 - (15ft)^2).

The question is asking for the height of the antenna. We can solve this problem by using the Pythagorean theorem, which states that in a right triangle the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Here, the hypotenuse is the length of the cable (50 ft), one side is the distance from the base of the antenna to the anchor point (15 ft) and the other side (which we are trying to find), is the height of the antenna.

According to the Pythagorean theorem, the height of the antenna can be calculated as follows: Height = √(Hypotenuse^2 - Base^2), which translates into Height = √((50ft)^2 - (15ft)^2). When you calculate that you get the height of the antenna as approximately 47.4 feet, rounded to the nearest tenth.
