E(t) is the elevation Maria is at at t minutes.

The expression to calculate the elevation is 1200 + 40t.

E(t) = 1200 + 40t

E(15) means the elevation Maria is at at time 15 minutes.

E(15) = 1200 + 40(15)

E(15) = 1200 + 600

E(15) = 1800

E(15) = 1800 means that Maria is at an elevation of 1800 ft after 15 minutes.

X to the second power equals 14
yaroslaw [1]
X to the second power equals 14 is the same as:
x^{2}=14
we can take the square root of both sides to get:
x= \sqrt{14}
because we cannot simplify the 14 inside the square root symbol, our final answer is
x= \sqrt{14}

Answer:

343

Step-by-step explanation:

<u>Let's start simplifying with the numerator:</u>

(15-8)⁹

=7⁹

=40353607

<u>Now simplify the denominator :</u>

[(5+2)³]²

=[(7)³]²

=[343]²

=117649

<u>Now combine them :</u>

(15-8)⁹/ [(5+2)³]²

=40353607 / 117649

=343

What is the value of i^20+1?<br> A. 1<br> B. –1<br> C. –i<br> D. i
lisov135 [29]

ANSWER

{i}^{20}  + 1 =2

EXPLANATION

The given expression is;

{i}^{20}  + 1

Recall that, in complex numbers

{i}^{2}  =  - 1

We use this identity to simplify the given expression:

{i}^{20}  + 1 =( {i}^{2})^{10}  + 1

This implies that:

{i}^{20}  + 1 =(  - 1)^{10}  + 1

{i}^{20}  + 1 =1+ 1

{i}^{20}  + 1 =2

A school is building a rectangular stage for its chorus. The stage must have a width of 4 feet. The area of the stage must be at
slavikrds [6]

Answer: Length ≥ 6 feet

Step-by-step explanation:

The area of a rectangle= length × width

In this case, the width is 4 feet and the area of the stage must be at most 24 square feet.

The inequality that describes the possible lengths (in feet) of the stage would be:

Length × Width ≥ 24

Length × 4 ≥ 24

Length ≥ 24/4

Length ≥ 6

Therefore, the length must be at most 6 feet.
