Answer:
a. 8.5 in.
b. 34 in
c. x = 1/39 x^2.
Step-by-step explanation:
Part a.
x = 1/34 y^2
y^2 = 34x
Comparing with y^2 = 4px where p is the focus:
4p = 34
p = 8.5 in.
Part b.
The diameter = 4p = 34 in.
Part c.
Diameter = 4p = 34 + 5 = 39 in
The new equation is x = 1/39 x^2.

Answer:
x = 245
Step-by-step explanation:
The sum of integers x and y is 280; x + y = 280
If x is divided by 7, the quotient is y; x/7 = y so x = 7y
Now you have 2 equations:
x + y = 280
x = 7y
Substitute x = 7y into x + y = 280
7y + y = 280
8y = 280
y = 35
x = 7(35)
x = 245
Answer
x = 245
21.1% of the total company is 13, 700 (as stated in the word problem). Therefore, 0.211x = 13, 700. Divide 0.211 on both sides: 64, 928.9099. The nearest whole number would result in 64, 929 employees.
