We will be using the cosine function to figure this out.
The ramp, ground, and platform form a right triangle.
The hypotenuse is 29, and the side adjacent to ∠x is 20.
SO:
Cos ∠x = 20/29
Cos ∠x = 0.68965517241379
Use the function on your calculator to find what angle has a Cos of 0.6896551
Cos 0.6896551 = 46.397°
ANSWER: the angle of elevation is 46.4°
Hope this helps! God bless. :)
Answer:
Step-by-step explanation:
<u>Assumed it is:</u>
<u>Converting into vertex form:</u>
- f(x) =
- - x² + 16x - 13 =
- - (x² - 16x + 64 - 64) - 13 =
- - (x - 8)² + 64 - 13 =
- - (x - 8)² + 51
Using the number line, the numbers that are 9 units from -5 are: -14 and 4.
<h3>How to Locate a Number on a Number line?</h3>
To find two numbers that cover the same units from a given point on a number line, we can simply do the following:
- Count the number of units given backwards/to the left from the point stated to get the first number.
- Count the number of units given forwards/to the right from the point stated to get the second number.
Thus, we are asked to find the numbers that would be 9 units from -5, using the number line.
Count 9 units backwards/to the left from -5 to get the first number, which is: -14
Count 9 units forwards/to the right from the -5 to get the second number, which is: 4.
Therefore, the numbers that are 9 units from -5 on the number line, are: -14 and 4.

The area tom the right of the z-score of 2.75 under a statistical normal distribution curve will be given by:
1-P(z≤2.75)
but
P(z≤2.75)=0.997
thus
1-P(z≤2.75)
=1-0.997
=0.003
Answer: 0.003
Answer:
1. 4 times 8, the multiplication property 2. 34 minus 4, the subtraction property. 3. 14 divided by 3.5, the division property. 4. 10 + 6, the addition property.
Step-by-step explanation for all of the questions:
If the number in the beginning of the equation is being multiplied by another number, it is the multiplication property. It is the same for all of the other properties.
