Answer:

$3 {x}^{2} - 2x + 1$

$now \: \: x = 4$

$3 {(4)}^{2} - 2(4) + 1$

$3(16) - 8 + 1$

$48 - 8 + 1 = 41$

41 is the answer

Find an equation in slope-intercept form of the line that has slope –8 and passes through point (1,5)

Dovator [93]

Using the equation of the line
y -yo = m (x-xo)

We substitute xo,yo and the slope

y -5 = -8(x-1) .....> y = -8x +8 +5 = -8x +13

y = -8x +13

The answer is 27/23. The way you listed the answers is confusing so I’m not giving a letter. Because [17+10]/[17+6]= 27/23

The height in feet above the water of a diver can be modeled by ℎ() = −16*2 − 16 + 192, where t is the time in seconds after the

Maurinko [17]

h(t) is the height of the diver in feet above the water

Now it asks about the time at which diver reaches the water

When diver reaches the water , the height of diver from water should be zero

So we plug h(t) =0

$-16t^2 -16 t +192 =0$

divide whole equation by -16

$t^2 +t -12 =0$

we can now factor the quadratic equation

So we get

(t+4)(t-3) =0

plug each factor equal to zero and solve for t

t+4 =0 and t-3 =0

So t=-4 and t=3

Now time cannot be negative , So t=3

So time = 3 seconds

It takes 3 seconds for the diver to reach the water
