Answer:
domain of y = sqrt (x+4) is [-4, +inf)
Step-by-step explanation:
[-4, +inf), -4 is included because sqrt(-4 + 4) is defined but is undefined at the points from (-inf, -5].
<u>Answer:</u>
Below!
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- Length = Height = Width
- Volume = LHW = L³ = 64000
- Surface area = 6(area of a square)
<u>Part A Solution:</u>
- L³ = 64000
- ∛L³ = ∛64000
- => L = ∛40 x 40 x 40
- => L = 40 inches
Hence, the length is 40 inches.
<u>Part B Solution:</u>
We know that the length is 40 units. Since this is a cube, L must equal to W.
- => L² = 6(40 x 40)
- => L² = 6(1600)
- => 9600 square inches
Hence, the surface area is 9600 square inches.

Answer:
The answer is A
Step-by-step explanation:
y=1.3(5) + 10 = 16.5 ---> True
y=1.3( 10) + 10 = 23 ----> True
y=1.3(15) + 10 = 29.5 ----> True
y=1.3(20) + 10 = 36 ----> True
