Step-by-step explanation:

Multiply the area of the circle by [tex] \frac{360\degree - x}{360\degree} [/tex]

Answer:

-9, -2, 14

Step-by-step explanation:

-1 is < 0 so plug it into the first function.

8(-1) -1 = -9

0 is ≥ 0 so plug it into the second function

8(0)-2 = -2

2 is ≥ 0 so plug it into the second function

8(2) - 2 = 14

Answer:

y = 0.1(x + 5)² + 1.5

Step-by-step explanation:

Equation of a parabola having vertex at (h, k) is given by,

y = a(x - h)² + k

From the given graph, vertex of the parabola is (-5, 1.5)

Therefore, equation of the parabola will be,

y = a(x + 5)² + 1.5

Since, this parabola passes through a point (0, 4)

4 = a(0 + 5)² + 1.5

4 = 25a + 1.5

25a = 2.5

a = 0.1

By substituting the value of 'a' in the equation of the parabola,

y = 0.1(x + 5)² + 1.5

Since there are two cars, each car, then, drove 104/2 = 52 miles. But one car is traveling 8 miles per hour faster.

Step-by-step explanation:

Answer:

2(4x-5)

Step-by-step explanation:

find the greatest common factor (biggest number that goes into 8 and 10)

it is two

divide both by two

put 2 on the outside to symbolize that you multiply the inside by 2

2(4x-5)

Answer:

[tex]2(4x - 5)[/tex]

Step-by-step explanation:

1) Find the Greatest Common Factor (GCF).

[tex]gcf = 2[/tex]

2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

[tex]2( \frac{8x}{2} - \frac{10}{2} )[/tex]

3) Simplify each term in parentheses.

[tex]2(4x - 5)[/tex]

Therefor, the answer is Option B.

Answer:

500 families

Step-by-step explanation:

We want to estimate the size of the dark blue section of the chart. The chart looks like the left of the pie chart is split evenly with the dark blue section. So we estimate that each of those must represent 12 or 50% of the total number of families. Therefore,

0.50⋅1000=500

About 500 families own a van.

Answer:

This is false

Step-by-step explanation:

Answer:

I totally get why you are asking , how do I solve this.  there is so much implied about this

Step-by-step explanation:

1st you have to recognize that ∠ACB ( in my drawing ) has that same angle as the arc from A to B  ,  so that's implied.   next you have to recognize that the triangle formed by ACB with the 124 degree angle at C is an isosceles and therefore has identical angles at A and B  so that's  180 = 124 + 2A  , so A = 28° and so does B , then , b/c we know that small angle... you also have to know, that the line AC is perpendicular to AD.  that they from a right angle and there for... you now know , that ∠BAD is the other part of that 90 or 90= 28 + ∠BAD so  ∠BAD = 62°

I went through that kinda fast, there was several "leaps" of using logic to get to the correct answer , using things you know from prior understanding about angles , circles  and geometry,  you are putting all of the parts together here.  :/  kinda daunting in some ways.

Answer:

At x = 7 and x= 1

Step-by-step explanation:

Set each equation equal to 0 and solve.

x - 7 = 0

x = 7

x-1 =0

x = 1

Answer:

7

Step-by-step explanation:

did the question

The amount of money would be $6,880 in the account after 7 years.

Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.

A = P(1+r/100)ⁿ

Where:

A = the future value of the investment or loan

P = the principal investment or loan amount

r = the interest rate (decimal)

n = the number of compound periods

Given data as follows:

p = $5,300

r = 3.8%

A = $6,880

A = P(1+r/100)ⁿ

Substitute the values of p,r, and A in the formula,

6,880 = 5,300(1 + 3.8/100)ⁿ

6,880/5,300 = (1 + 0.038)ⁿ

1.2981 = (1.038)ⁿ

n = 6.9954

Rounded to the nearest digit, and we get

n = 7

Therefore, the amount of money would be $6,880 in the account after 7 years.
