Answer:
She is 90 feet above ground before she begins to descend.
She descends by a rate of 5 feet per second.
Step-by-step explanation:
She is 90 feet above ground before she begins to descend. You can see that by looking at the y value of the highest point of the line, which is just between 80 and 100, which is 90.
We can find the rate of her descending by finding the slope. Remember that the slope formula is (y1-y2)/(x1-x2)
We can find two points on the line and plug the x and y values in. Let's use the points (0, 90) and (16, 10).
We plug the values in:
(90-10)/(0-16)
(80)/-16
-5
The slope is negative, which makes sense, because Aretha is descending and not ascending.
So, she is descending by a rate of 5 feet per second.

Answer:
The factors are
Step-by-step explanation:
we have
equate the expression to zero
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
Take square root both sides
therefore
Answer:
-96
Step-by-step explanation:
When you subtract a positive number from a negative number you add the two numbers together and then make it a negative so 44 + 52 = 96 then you make it a negative so it will be <u>-96.</u>
Hope this helps!!

The missing coefficient of n in n + 8 is 9 after adding like terms which is 2n and 7n.
<h3>What is an expression?</h3>
It is defined as the combination of constants and variables with mathematical operators.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have an expression:
= 2n + (7n + 8)
After adding like terms:
9n + 8
The coefficient of n in n + 8 is 9
Thus, the coefficient of n in n + 8 is 9 after adding like terms which is 2n and 7n.
