What is the effect on the graph of the function f(x) = 2x when f(x) is replaced with f(0.5x)? A) vertical stretching B) vertical

PtichkaEL [24]

<h3><u>Answer:</u></h3>

Option: D

Horizontal stretching.

<h3><u>Step-by-step explanation:</u></h3>

We have to find the effect on the graph of the function f(x)=2x when it is replaced by f(0.5 x).

We know that when a parent function f(x) is replaced by f(kx) then either the graph is stretched horizontally or shrinked horizontally.

if k>1 then the graph is shrinked horizontally.

if k<1 then the graph is stretched horizontally.

Hence here k=0.5<1 so the graph of the function is stretched horizontally.

An Uber fare in Columbus is $3.50 for the first ½ mile and additional mileage charged at a rate of $0.30 for each additional 0.1

Verizon [17]

Answer:

$\frac{11}{3}$ miles

Step-by-step explanation:

Let the total miles traveled be x.

Now, for the first 0.5 miles total charge is = $3.50

Then, the remaining distance to be traveled $=(x-0.5)$ miles

For each additional 0.1 mile, the additional charge is $0.30

So, for $(x-0.5)$ miles, the total additional charge will be $=\frac{0.3}{0.1}(x-0.5) =3(x-0.5)$

Then, including the $2 tip, the total fare will be $=3.50+3(x-0.5)+2$

Now, given that total fare is $15, so,

$3.50+3(x-0.5)+2=15\\3.50+3x-1.5+2=15\\3x+4=15\\3x=11\\x=\frac{11}{3}$ miles

What is the probability of rolling an even number or a perfect square using a 20-sided die?

Gemiola [76]

Answer:

C) 12/20

Step-by-step explanation:

Between 1 and 20, 10 numbers are even, 4 numbers are perfect squares (1, 4, 9, and 16), and 2 numbers are both even and perfect squares (4 and 16).

So the probability is:

(10 + 4 − 2) / 20 = 12/20.
