A ball is thrown upward from the top of a building. The function below shows the height of the ball in relation to sea level, f(

ratelena [41]

Answer:

The average rate of change of f(t) from t = 3 seconds to t = 5 seconds is -80 feet per second.

Step-by-step explanation:

The function that models the height of the ball is:

$f(t)=-16t^2+48t=160$

At t=3, $f(3)=-16(3)^2+48(3)+160=160$

At t=5, $f(5)=-16(5)^2+48(5)+160=0$

The average rate of change is simply the slope of the secant line connecting.

$(3,f(3))$ and $(5,f(5))$ .

The average rate of change

$=\frac{f(3)-f(5)}{3-5}$

$=\frac{160-0}{-2}$

$=-80fts^{-1}$

2x2 − 2z4 + y2 − x2 + z4 if x = −4, y = 3, and z = 2.

gavmur [86]

2(-4)2=-16
-2(2)4=-16
(3)2=6
-(-4)2=8
(2)4=8
8+8=16+6=22-16=6-16=-10
-10 is the final answer.

Solve 2x - y = -6 if the domain is (-2,-1, 0, 1).

MAVERICK [17]

Answer:

y = 2, y = 4, y = 6, y = 8

Step-by-step explanation:

We are given an equation 2x - y = - 6.

We have to solve it.

The linear two-variable equation can be rearranged as y = 2x + 6 ........ (1)

Now, we need x values to get corresponding y values.{Since, there are two variables and only one equation}

It is given that the domain is (- 2, - 1, 0, 1).

Therefore, those are the x values for which we have to solve for y from equation (1).

For, x = - 2, y = 2( - 2 ) + 6 = 2 (Answer)

For, x = - 1, y = 2( - 1 ) + 6 = 4 (Answer)

For, x = 0, y = 2( 0 ) + 6 = 6 (Answer)

For, x = 1, y = 2( 1 ) + 6 = 8 (Answer)

6x2 + 5x + 1<br>how do I factor this out?

Oduvanchick [21]

Answer:

(3x + 1) (2x + 1)

Step-by-step explanation:

ax² + bx + c can be factored using the AC method:

1. Multiply a and c.

2. Find factors of ac that add up to b.

3. Divide each factor by a; reduce the fractions.

4. The denominator is the coefficient, the numerator is the constant.

6x² + 5x + 1

1. ac = 6 × 1 = 6

2. Factors of 6 that add up to 5: 2 and 3.

3. 2/6 = 1/3, and 3/6 = 1/2

4. The factors are 3x+1 and 2x+1.

6x² + 5x + 1 = (3x + 1) (2x + 1)
