Answer:

4 \sqrt{2} i

Step-by-step explanation:

We seek the total of

\sqrt{ - 2}  +  \sqrt{ - 18}

This can be reformulated as

\sqrt{ 2 \times  - 1}  +  \sqrt{ 18 \times  - 1}

Which simplifies to;

\sqrt{2}  \times  \sqrt{ - 1}  +  \sqrt{18}  \times  \sqrt{ - 1}

Bear in mind that;

i =  \sqrt{ - 1}

This suggests that;

\sqrt{2} i + 3 \sqrt{2} i

Combine similar elements:

4 \sqrt{2} i

A rocket was launched into the air from a podium 6 feet off the ground. The rocket path is represented by the equation h(t)=-16t
lawyer [12517]

Answer:

60

Step-by-step explanation:

The function provided is:

h(t)=-16t^2+120t+6

The average rate of change of h(t) as time goes from t=a to t=b is expressed as:

\frac{h(b)-h(a)}{b-a}

This function can be reformulated as: h(t)=-16(t-3.75)^2+231

The rocket's peak height is 231, which occurs at t=3.75 seconds.

\implies h(3.75)=231

The initial launch happens at: t=0

and h(0)=-16(0)^2+120(0)+6=6

The average rate of change from launch to max height is

\frac{h(3.75)-h(0)}{3.75-0}=\frac{231-6}{3.75-0} =60

A storage closet holds twelve boxes stacked upon each other, with each box being 10 inches high. How many feet are there between
babunello [11817]

Answer: 5

Explanation step-by-step: There are six boxes stacked between the top of the third box and the bottom of the tenth box.

Since each box measures 10 inches in height, the combined height of these six boxes is 60 inches.

Given that 12 inches equals 1 foot,

60 inches corresponds to 5 feet.

How to find the answer:

Let "y" represent the unknown length in feet.

12 inches = 1 foot

60 inches = y

Using cross multiplication:

> 12 × y = 60 × 1

> 12y = 60

Divide both sides by 12 to solve for "y":

> 12y ÷ 12 = 60 ÷ 12

After simplification, we get:

> y = 5
