Answer:

Step-by-step explanation:

Assume the surface area = 6x²

6 is the number of faces and x is the length of the cube

so 3/2 = 6x²

Divide by 6

1/4 = x²

Square root both sides

1/2 = x

Volume is : l×w×h

so 1/2 × 1/2 × 1/2 = 1/8

It's just like multiplying and dividing a negative, such as -1 *2=-2 and -2 / 1= -1

if there is one negative then it will be negative, so in this case it will be -7 / 2=

The function f(x) = 2x2 + 6x - 12 has a domain consisting of the integers from -2 to 1, inclusive. Which set represents the corr

Dimas [21]

Answer:

[-16,-4]

Step-by-step explanation:

We are given that

$f(x)=2x^2+6x-12$

Domain=[-2,1]

We have to find the set of range values of f(x).

Substitute x=-2

$f(-2)=2(-2)^2+6(-2)-12$

$f(-2)=-16$

Substitute x=1

$f(1)=2(1)+6(1)-12=-4$

Range of f(x)=[-16,-4]

Hence, the set of range values of f(x)

[-16,-4]

Answer:

see explanation

Step-by-step explanation:

Multiply both sides by 9 to eliminate the fraction

9K = 5(F + 459.67) ← divide both sides by 5

F + 459.67 = $\frac{9}{5}$ K ( subtract 459.67 from both sides )

F = $\frac{9}{5}$ K - 459.67

Can y’all please help meee

ElenaW [278]

Step-by-step explanation:

a. the domain ={-3, 0, 1, 2}

the range = {6, 2, 0, -3}

the relation is a function

b. the domain = {-1, 2, 1}

the range = { -4, 8, 4}

the relation is not a function
