The functions u and w are defined as follows.
u(x) = 2x+2
w(x) = – 2x² +2
Find the value of w (u(2)).

Answers

Answer:

w(u(2)) = -70

Step-by-step explanation:

u(x) = 2x + 2

w(x) = -2[tex]x^{2}[/tex] + 2

w ( u (2) )

Find u(2), substitute in 2 for x in the function u.

u(2) = 2(2) + 2

= 4 + 2

= 6

w(u(2))

= w(6)

Now subsitute in 6 for x, in the function w.

w(6) = -2[tex](6)^{2}[/tex] + 2

= -2 * 36 + 2

= -72 + 2

= -70

w(6) = -70

w(u(2)) = -70

Olivia is going to use a computer at an internet cafe. The cafe charges an initial fee to use the computer and then an additional price per minute of usage. An equation representing the total cost of using a computer for tt minutes at the internet cafe is given by C=0.10t+7.C=0.10t+7. What is the slope of the equation and what is its interpretation in the context of the problem?

Answers

Answer:

Slope=0.10

Interpretation: For every minute Olivia is in the cafe she is getting charged 10 cents

Step-by-step explanation:

The slope is a constant followed by a variable (a,x,b,z,etc...) So the only constant with a variable after it was the 10.

Answer:

The slope of the function is 0.10 which represents the additional charge per minute.

Step-by-step explanation:

The slope shows how much the amount Olivia must pay increases each minute, representing the cost per minute of using the computer after the initial charge.

b) Amount
Rs 5760, Interest
Rs 1526​

Answers

Given :

Amount, A = 5760 Rs.

Interest in the amount, I = 1526 Rs.

To Find :

We need to find the % rate of interest.

Solution :

Let, us assume it is simple interest.

So,

[tex]Interest = \dfrac{price \times rate \times time}{100}\\\\1526 = \dfrac{5760 \times r \times m}{100}\\\\r = \dfrac{152600}{5760m}\\\\r = \dfrac{26.5}{m}[/tex]

Hence, this is the required solution.

Given the relation: (0,0), (5,10), (6,12), (10,20) and based on the definition of function, is that relation a function?

Why or why not?

On the interval [x,7] , at which x-value is the average rate of change 56?
????????

Answers

Average rate of change of 56 at the point x=4

What is average?

An average is a single number taken as representative of a list of numbers

What is rate of change?

A rate of change is a rate that describes how one quantity changes in relation to another quantity

Consider the point 4

At x=4; f(x)=24

At x=7: f(x)=192

Average Rate of change = Rate of change of f(x) / Rate of change of x

Average rate of change =[tex]\frac{192-24}{7-4}=\frac{168}{3}[/tex]

Average rate of change = 56

Hence, the average rate of change of 56 at the point x=4

It's candy time! Suppose 5 friends go out candy collecting. Starting out, Ms. Gleason gave each of them 12 pieces of candy. Then, they each collect 15 pieces each hour. At the end of the night, the 5 friends have 510 pieces all together. How many hours were they out candy collecting? ______ hours Multi-Step Equations

Answers

Answer:

6 hours

Step-by-step explanation:

First, since they all collected 510, you divide 510 by 5, to figure out how much each person got.

You then know that each of them got 102 candies, so now, you subtract 12 from from 102, since the teacher gave them that much in the beginning.

You're left with 90, so last step is to divide 90 by 15, since they collect 15 every hour, which you get left with 6. Meaning they collected candies for 6 hours

Answer:

they were out for 6 hours and each of them got 102 pieces of candy
