What is the y-intercept of the graph of the function f(x) = x2 + 3x + 5?

agasfer [191]

Answer:

(0,5)

Step-by-step explanation:

If you plug in 0 in all the variables of x, f(x)=0+0+5

We know that f(x) is y...so y=5, while x=0

The value of y varies directly with c. If x = 2, then y = 7. Find the value of x if y = 84.

shtirl [24]

Answer:

x=24

Step-by-step explanation:

y = x*c

x=2, y=7

2*c=7 => c=7/2

x*7/2 = 84

x = 84*2/7

x = 12*2

x = 24

Find the contrapositive for the following statement if you are in college, then you graduated from high school

Colt1911 [192]

Answer:

If you didn't graduate from High school ,Then you are not in college

Step-by-step explanation:

statement :

if you are in college, then you graduated from high school

In the given statement we have :

The Hypothesis is : you are in college

The conclusion is : you graduated from high school

in order to get the contrapositive ,

• first we switch the hypothesis and the conclusion

( H ⇒ C becomes C ⇒ H )

• Second, we negate the hypothesis and the conclusion.

Then

• first ,if you graduated from high school , then you are in college

• second , If you didn't graduate from High school ,Then you are not in college

Polynomial Functions in context. a. A baseball is struck such that its position on a plane perpendicular to home plate can be de

Brums [2.3K]

The position of the ball when it is at its highest point is 121

<h3>Polynomial function</h3>

Given the polynomial function expressed as y = -1/250(x - 175)^2 + 121,

The velocity of the ball at the maximum point is zero. Hence;

dy/dx = -1/125(x-175)

Equating to zero;

0 = -1/125(x - 175)

x = 175

Substitute into the function to get the maximum height

y = -1/250(175 - 175)^2 + 121,

y = 121

Hence the position of the ball when it is at its highest point is 121
