sineoko [7]3 years ago

Answer:

The correct option is d.

Step-by-step explanation:

The given functions are

f(x)=7+4x

g(x)=\frac{1}{2x}

Substitute x=5 in each function.

f(5)=7+4(5)=7+20=27

g(5)=\frac{1}{2(5)}=\frac{1}{10}

We need to find the value of (f/g)(5).

(\frac{f}{g})(5)=\frac{f(5)}{g(5)}

Substitute f(5)=27 and g(5)=\frac{1}{10} in the above equation.

(\frac{f}{g})(5)=\frac{27}{\frac{1}{10}}

(\frac{f}{g})(5)=27\times 10=270

The value of  (f/g)(5) is 270. Therefore the correct option is d.

<h2>Answer:</h2>

d. \ \boxed{270}

<h2>Step-by-step explanation:</h2>

In this exercise we need to make a division and evaluate the new function at x=5. so we have two functions, namely:

f(x)=7+4x \ and \\ \\ g(x)=\frac{1}{2x}  

Therefore:

f(5)=7+4(5)=27 \\ \\ g(5)=\frac{1}{2\times 5}=\frac{1}{10}

So:

(f/g)(5)=\frac{27}{\frac{1}{10}}=270

Evaluate the function below for x=3<br> F(x)= 2x^3-x^2-4x+9
agasfer [191]

Answer:

42

Step-by-step explanation:

f(3)=2(3)^3-(3)^2-4(3)+9

f(3)=2(27)-(9)-12+9

f(3)=54-21+9

f(3)=33+9

f(3)=42

What is 497÷2 (Use long division on a piece of paper) Explain how you figured this out clearly so I can play along because I won
erma4kov [3.2K]
Dividing 2 into 4 you would get 2 and dividing it into 9 you would get 4 since you can't divide it into 9 so when you subtract that (9-8) you would get 1 you place a decimal and bring down a zero to get 10 then you would get 5 the answer would be 248.5

Verda used a sensor to measure the speed of a moving car at different times. At each time, the sensor measured the speed of the
USPshnik [31]

Answer:

Option A

Step-by-step explanation:

If the speed of a car in miles per hour (m) is proportional to the speed in kilometers per hour (k),

m ∝ k

m = ck

Here, c = Proportionality constant

Therefore, c = \frac{m}{k} should be constant for each value given in the table.

For m = 11 and k = 17.699,

c = \frac{11}{17.699}

c = 0.6215

For m = 26 and k = 41.834,

c = \frac{26}{41.834}

c = 0.6215

For m = 34 and k = 54.706,

c = \frac{34}{54.706}

c = 0.6215

Therefore, c is constant for each value of m and k.

Option A will be the correct option.
