Refer to the table of long distance rates. Write an expression that can be used to find the cost of an n-minute long distance call, where n is at least 5 minutes.

Answers

Answer:

a(n) = 0.55 + (n -5)0.07

Step-by-step explanation:

The cost goes up $0.07 for each additional minute, so that is the slope of the linear function. In point-slope form the equation can be written ...

... a(n) - 0.55 = 0.07(n -5)

adding 0.55, and rearranging slightly, this becomes ...

... a(n) = 0.55 +(n -5)0.07

The set of all possible vectors you can reach with the linear combination of two vectors is called ________________.

The set of all possible vectors you can reach with the linear combination of two vectors is called the linear span of the set of two vectors.  

We often write the span of a set of vectors S as span(S) and it's itself a vector space, a subspace of the vector space from which the elements of S are drawn.

How does the graph change from f(x) to g(x)?

Select each correct answer.

Answers

Answer:

B and C

Step-by-step explanation:

There are two ways of looking at this question. You can do it algebraically or you can make a graph that will give you the answer visually.

Graph

I'll try to do both. First the graph. (See below)

The red line is f(x)The blue line is g(x)

The graph tells us that the line is shifted

2 units up (blue is above red) and 3 units to the left (blue is to the left of red)

Algebra.

g(x) = 2^[(x - 1) + 3] + 3 (+ 2)

The rewrite shows that +3 means left. +2 means up.

10. It is a parallelogram.

11. The parallelogram is a rhombus.

Step-by-step explanation:

10. Use the given sets of congruent segments with congruent vertical angles XNY and WNZ to prove that triangles XNY and ZNW are congruent. Now use CPCTC to show that angles XYN and ZWN are congruent. They are alternate interior angles making sides XY and WZ parallel. Now use CPCTC to show that sides XY and WZ are congruent. Since a quadrilateral has two opposite sides that are both parallel and congruent, the quadrilateral is a parallelogram.

11. A rectangle and a square have 4 right angles. If you add 72 deg and 72 deg, you get 144 deg which is not a right angle. Since one angle of the parallelogram is not a right angle, the parallelogram is not a square or a rectangle.

There are two triangles. Let's look at the upper triangle. The triangle has 2 angles measuring 72 deg each. That means the opposite sides are congruent, and the triangle is isosceles. Since the quadrilateral is a parallelogram, opposite sides are congruent, so all 4 sides are congruent, and the parallelogram is a rhombus.

Answers

75% of 0.5 gallons = 75/100 × 0.5 = 0.375 gallons.

Olivia drinks 0.375 gallons of water.

What is problem-solving?

Problem-solving is defining a problem; figuring out the purpose of the trouble; identifying, prioritizing, and selecting alternatives for an answer; and imposing an answer.

Problem-solving starts with identifying the issue. For example, a trainer may need to figure out a way to improve a scholar's overall performance on a writing talent test. To do that, the instructor will overview the writing exams looking for regions for improvement.

Calculation:-

Quantity of water Olivia took = half a gallon i.e 0.5 gallons.

Quantity of water Olivia drank =0.75 of 0.5

      ∴  75% of 0.5 gallons

          = 75/100 × 0.5

           = 0.375 gallons.

Calculate the distance between the points K = −1, −4 and L = −82 in the coordinate plane.
Give an exact answer (not a decimal approximation).

Answers

Answer:

√85

Step-by-step explanation:

The distance formula tells you the distance between (x1, y1) and (x2, y2) is ...

... d = √((x2-x1)^2 +(y2-y1)^2)

For your points (-1, -4) and (-8, 2), the distance is ...

... d = √((-8 -(-1))^2 +(2 -(-4))^2) = √((-7)^2 +6^2) = √(49 +36)

... d = √85

The distance between the two points is √85.

choose the quadratic equation that has a leading coefficient of 8 and solutions -10 and 7/8

Answers

Answer:

[tex]f(x)=8x^2+73x-70[/tex]

Step-by-step explanation:

We are given

zeros as -10 and 7/8

now, we can set up function as

[tex]f(x)=a(x-(-10))(x-\frac{7}{8})[/tex]

now, we are given that

leading coefficient is 8

so, a=8

now, we can plug it

[tex]f(x)=8(x-(-10))(x-\frac{7}{8})[/tex]

now, we can simplify it

[tex]f(x)=8\left(x^2+\frac{73x}{8}-\frac{35}{4}\right)[/tex]

so, we get

How to solve this problem?

Answers

Answer:

Can not be determined.

Step-by-step explanation:

We can easily notice that the limit is x tends to infinity, whereas x is not present in the given function, we are given (1 + 1/n). So we can not evaluate the given limit for x as parameter, we must have some function of x to solve this problem.

Hence, option C is correct i.e. the limit can not be determined.

(1) Tom took a trip of 1,020 miles. He traveled by train at 55 miles an hour and the same number of hours by plane at 285 mph.


How many hours did the trip take?


A) 3 hours

B) 6 hours

C) 8 hours

Answers

Answer:

B) 6 hours

Step-by-step explanation:

Let h represent the total trip time. Then h/2 is the time spent traveling at each speed. The distance covered is ...

... distance = speed · time

The sum of the distances in each mode is the total distance.

... 1020 = 55·h/2 +285·h/2

... 2040 = h·(55+285) . . . . multiply by 2

... 2040/340 = h = 6 . . . . . . . divide by the coefficient of h

The trip took a total of 6 hours.

How many different four lettered codes can be formed if the first letter must be an S or a T

Answers

Answer:

27,600

Step-by-step explanation:

We use the following formula:-  

Number of permutations of r from n

= nPr

= n! / (n-r)!

I am assuming you don't allow repeated letters in the 4 letter codes.

Take S as the first letter. Then we have 3 letters extra out of 25 letters.

Using the above formula the possible ways of doing this is

25! / (25 - 3)!

25! / 22!

= 25*24*23

= 13800.

The same number is obtained if the first letter is a T.

So the answer is 2*13800

= 27,600

for 2335+3x-11=23
3x=23+11-2335
=-2301
x =-2301/3
=-767.00
Final answer:

The solution to the first equation 4x – 5 = 16 is x = 5.25. The solution to the second equation 35 + 3x – 11 = 23 is x = -0.33. Both solutions have been rounded to two decimal places.

Explanation:

Let's solve these two equations one by one:

a. 4x – 5 = 16

Add 5 to both sides of the equation: 4x = 16 + 5 Simplify right side: 4x = 21 Divide both sides by 4 to solve for x: x = 21/4 = 5.25

b. 35 + 3x – 11 = 23

Simplify the left side by combining like terms: 3x + 24 = 23 Subtract 24 from both sides to isolate the term with x: 3x = 23 - 24 Simplify right side: 3x = -1 Divide both sides by 3 to solve for x: x = -1/3 = -0.33

These are the solutions to the equations, rounded to two decimal places.

You are missing a sign between -5 and the square root
