Answer 1
Answer:

Answer:

Option (a) is correct.

The Juan’s initial investment is $ 5

Step-by-step explanation:

Given : Juan’s investment account can be modeled by the function,c(x)=7x^2-6x+5, in thousands of dollars.                        

We have to find the  Juan’s initial investment.

Since,  Juan’s investment is modeled by function

c(x)=7x^2-6x+5

Since initial investment is when he start the investment and is given by when

x = 0

Thus,  c(0)=7(0)^2-6(0)+5

Simplify , we get,

c(0) = 5

Thus, the Juan’s initial investment is $ 5
Answer 2
Answer: initial investment was when x=0, when no change had occured

c(0)=7(0)^2-6(0)+5
c(0)=5

this is in thousands
5*1000=5000
answer is $5000 is initial

A student runs 100 meters in 11 seconds. What is the speed of the student? 9.1 miles per hour 16miles per hour 20.3miles per hour 24miles per hour

Answers

The answer is 20.3 miles per hour. First, you need to change meter and second to mile and hour. The 100 meter equals 100/1609 mile. 11 seconds equals 11/3600 hour. Then using mile number divides by hour you can get the answer.

For what values of k does the equation x^2 - (5k+1)x + 9k^2 = 0 have real roots?

Answers

K has a range from[ -1/11 to 1]
real roots occur when the determinant b^2-4ac >= 0

so substituting:-

(5k + 1)^2 - 4*1* (9k^2) >= 0
25k^2 + 10k + 1 - 36k^2 >= 0
-11k^2 +10k  + 1 >= 0
11k^2 - 10k - 1 <= 0
(11k + 1)(k - 1) <=  0

the equation will have real roots for  -1/11 =< k <= 1

The formula P = 2L + 2w represents the perimeter of a rectangle. In this formula,L is the length of the rectangle and w is the width. Solve the formula for L. Find
the length when the width is 4 meters and the perimeter is 36 meters.

Answers

The length of a rectangle is 14 meters when the width is 4 meters and the perimeter is 36 meters.

What is the perimeter of the rectangle?

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

The perimeter of a rectangle = 2(L+W)

Where W is the width of the rectangle  and L is the length of the rectangle

We have been given that,

The formula P = 2L + 2W represents the perimeter of a rectangle.

To determine the length when the width is 4 meters and the perimeter is 36 meters.

The perimeter of a rectangle = 2(L+W)

Here W =  4 meters

⇒ 36 = 2L + 2(4)

⇒ 36 = 2L + 8

⇒ 2L = 28

⇒ L = 14

Therefore, the length of a rectangle is 14 meters.
