Is there a picture to go with it?
Answer: -43.3
Step-by-step explanation:
We will use the order of operations, sometimes called PEMDAS. <em>See attached for more information on this subject</em>.
Given:
8.7 - (1 + 3)³ + 6 · 2
Simplify parentheses:
8.7 - (4)³ + 6 · 2
Raise to the power of three:
8.7 - 64 + 6 · 2
Multiply:
8.7 - 64 + 12
Subtract:
-55.3 + 12
Add:
-43.3
Answer:
4
1.5(x+4) - 3 = 4.5( x-2)-----------------------open brackets on both sides
1.5 x +6 -3= 4.5x- 9.................................collect like terms
3+9 = 4.5 x- 1.5x
12=3x..................................divide by 3 both sides to get x
12/3=x
x=4
The depth of the diver is 32 feet below sea level.
<h3>What is the angle of elevation?</h3>
The angle of elevation is the angle between the observer's eyesight horizontal line and the object. The complete question can be seen in the image attached below.
The depth of the diver is the absolute value of -32 since it can't be negative.
= |-32|
= 32
Therefore, we can conclude that the depth of the diver is 32 feet below sea level.
