Step-by-step explanation:

x - 4x - 12 = (x __ 2)(x ____ 6)

when they add negative

when they're multiplied negative

(x+2)(x-6)

because when u add them -6+2=-4

when u multiply them -6*2= -12

Solve R = cs\d for C

GaryK [48]

Answer:

c=rd/s

Step-by-step explanation:

r=cs/d

Times both sides by d

rd=cs

switch it around so c is on the left

cs=rd

divide both sides by s

c=rd/s

What is the volume of a hemisphere with a radius of 3.8in, rounded to the nearest tenth of a cubic inch

Pavel [41]

Answer: $114.9\ in.^3$

Step-by-step explanation:

Given

The radius of the hemisphere is $r=3.8\ in.$

The volume of a hemisphere is given by

$V=\dfrac{2}{3}\pi r^3$

Insert the value

$V=\dfrac{2}{3}\pi \times (3.8)^3\\\\V=114.9\ in.^3$

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by th

barxatty [35]

Step-by-step explanation:

I assume that "ground" is at 0 ft height. which is in an actual scenario not airways the case.

y = -16x² + 64x + 89

shows us that the tower is 89 ft tall (the result for x = 0, at the start).

anyway, if the original assumption is correct, then we need to solve

0 = -16x² + 64x + 89

the general solution for such a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/)2a)

in our case

a = -16

b = 64

c = 89

x = (-64 ± sqrt(64² - 4×-16×89))/(2×-16) =

= (-64 ± sqrt(4096 + 5696))/-32 =

= (-64 ± sqrt(9792))/-32

x1 = (-64 + 98.95453501...)/-32 = -1.092329219... s

x2 = (-64 - 98.95453501...)/-32 = 5.092329219... s

the negative solution for time is but useful here (it would be the time calculated back to ground at the start).

so, x2 is our solution.

the rocket hits the ground after about 5.09 seconds.

1.Suppose f(x)=6x^2+2x-7 and g(x)=4x-3.Find the value of f(5)/g(-3)

posledela

Answer:

-10.2

Step-by-step explanation:

f{5} = 6(5^2) + 2(5) - 7

g{-3}= 4(-3)-3

= 6(25) + 10 - 7

-12 - 3

= 150 + 10 - 7

- 15

= 153

-15

= -51

= -10.2
