Answer:

h ( -6 ) = -13228

Step-by-step explanation:

h ( x ) = -10x^(4) - 9x^(2) - 8x + 8

evaluate when, x = -6

Substitute in -6, for x,

-10(-6)^(4) - 9(-6)^(2) - 8(-6) + 8

= -10(1296) -9(36) -8(-6) + 8

= -12960 - 324 + 48 + 8

= -13284 + 56

= - 13228

What is the gcf of 48m^5n and 81m^2n^2

JulijaS [17]

Answer:

gcf is $3m^2n$

Step-by-step explanation:

we are given

$48m^5n$ and $81m^2n^2$

Firstly, we will find factors of both expression

$48m^5n=2\times 2\times2\times 2\times 3\times m^2\times m^3\times n$

$81m^2n^2=3\times 3\times 3\times 3\times m^2\times n\times n$

now, we will find common factors among them

we can see that

For finding gcf, we always find common factors

so,

common terms are 3,m^2 and n

so, gcf is

$=3\times m^2\times n$

$=3m^2n$

A rock is thrown from the top of a tall building.The distance in feet between the rock and the ground t seconds after thrown is

marusya05 [52]

Answer:

0.448 seconds

Step-by-step explanation:

d = -16t² -4t + 412

find t when d = 407

substituting d = 407 into the equation:

407 = -16t² -4t + 412 (subtract 407 from both sides)

-16t² -4t + 412 - 407 = 0

-16t² -4t + 5 = 0 (multiply both sides by -1)

16t² + 4t - 5 = 0

solving using your method of choice (i.e completing the square or using the quadratic equation), you will end up with

t = (-1/8) (1 + √21)= -0.70 seconds (not possible because time cannot be negative)

t = (-1/8) (1 -√21) = 0.448 seconds (answer)
