Quotient rule says we can divide 192 and 3 because they are both under the radical. This gives us the square root of 64.

We can also divide x^3 and x to get x^2.

The square root of 64x^2 is 8x

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.

Number of people can hold in each car = 10

Solution:

Number of cars in the Blazing Bullet = 6

Total number of people can ride at one time = 60

Number of people can hold at one Bullet car = ?

Let n be the number of people in each car can hold.

Now write a equation to find the number of people in each car.

Number of cars × number of people in each car = Total number of people

⇒ 6 × n = 60

⇒ 6n = 60

Now, solving this equation.

⇒ 6n = 60

Divide both sides of the equation by 6.

$$ \Rightarrow\frac{6n}{6} = \frac{60}{6}$

$$ \Rightarrow n=10$

⇒ n = 10

Hence 10 people can hold in each car.

In ΔVWX, the measure of ∠X=90°, WV = 17, VX = 15, and XW = 8. What ratio represents the sine of ∠W?

Dahasolnce [82]

Answer:

$Sin \ \angle W=\frac{15}{17}$

Step-by-step explanation:

-In a right triangle, the Sine of the base acute angle is usually given as:

$Sin \angle (base)=\frac{Opposite \ Length}{Hypotenuse}$

-In ΔVWX,, VX is the opposite and WV the hypotenuse.

-Therefore, sine of ∠Wis calculated as;

$Sin \ \angle W=\frac{Opp}{Hyp}\\\\=\frac{15}{17}$

Hence, sine of ∠W is given represented by the ratio $\frac{15}{17}$

Since y=Mx+b (Mx being slope and b being y intercept) you should plot a dot on (0,1) and then for the slope you would rise up 2 to 3 and then go over one to the point (3,1) I hope I could explain it well.
