Answer:

  • D. y = 6/5x + 2

Step-by-step explanation:

  • Initial height is 2 in
  • Height after 5 weeks is 8 in

<u>Rate of change is</u>

A bank has 23 employees. 3 employees get paid $20.93 an hour. 7 employees get paid $19.68 per hour. The other 13 get paid $23.00
miskamm [114]
Assuming each employee works 40 hours a week:
3 * 20.93 * 40 = 2511.60
7 * 19.68 * 40 = 5510.40
13 * 23.00 * 40 = 11960.00
2511.60 + 5510.40 + 11960.00 = $ 19,982.00

Answer:

\large\boxed{A=(223.3+49\pi)m^2}

Step-by-step explanation:

<em>(look at the picture)</em>

We have:

two halves of circle (whole circle) with radius r = 7m;

the suqare wih length side a = 14m;

the triangle with base b = 14m and hight h = 3.9m.

The formula of an area of a circle:

A_1=\pi r^2

Substitute:

A_1=\pi(7^2)=49\pi\ m^2

The formula of an area of a square:

A_2=a^2

Substitute:

A_2=14^2=196\ m^2

The formula of an area of a triangle:

A_3=\dfrac{bh}{2}

Substitute:

A_3=\dfrac{(14)(3.9)}{2}=(7)(3.9)=27.3\ m^2

The area of a figure:

A=A_1+A_2+A_3\\\\A=49\pi+196+27.3=223.3+49\pi
