XPY is the circumference minus XY

the angle of arc XY is 90 degrees

a full revolution of a circle is 360 degrees

the distance XY is 1/4 of the circumference of the circle

the circumference of a circle is C=2 pi r

r is 10m

the circumference is 20 pi

1/4 of 20 is 5

the distance of arc XY is 5 pi

20pi - 5 pi = 15 pi

The equation, y = 1250x + 22,850, gives the salary of a person as "y" after the stated number of years (x). Model the data with
Sidana [21]

Answer:

(a) y = 6250x +17850 --- The function

(b) y = 49100 --- The salary in 5 years

Step-by-step explanation:

Given

y = 1250x + 22850

Solving (a): Model the function around (1,24100) and (3,36600)

First, we calculate the slope

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{36600 - 24100}{3 - 1}

m = \frac{12500}{2}

m = 6250

The function is then calculated as:

y = m(x - x_1) + y_1

y = 6250(x - 1) + 24100

y = 6250x - 6250 + 24100

y = 6250x +17850

Solving (b): Salary in 5 years

Here:

x = 5

So:

y = 6250x +17850

y = 6250*5 +17850

y = 49100

For a class project, a teacher cuts out 15 congruent
True [87]

Answer:

60 -047 = 13 in²

Step-by-step explanation:

Paper area: 6 x 10 = 60

15 circles, each circle has diameter: 6 /3 or 10 /5 = 2

each circle area: πr² = 3.14 x 1² = 3.14

15 circles: 3.14 x 15 = 47.1

paper wasted: 60 - 47.1 ≈ 13 in²
