Answer:
b=-0.0019a + 215
at 2500 ft, b=210.25 degrees F
Step-by-step explanation:
First find the slope. a=altitude, b = temperature
slope is b2-b1 / a2-a1
points are (8200, 199.42) and (4700, 206.07)
(206.07 - 199.42) / (4700-8200)
= 6.65/ -3500
= - 0.0019
we have b = -0.0019a + intercept
plug in a point to find intercept
199.42 = -0.0019*8200 + intercept
intercept = 199.42 + 15.58 = 215
b=-0.0019a + 215
at a=2500 ft, substitute into equation
b= -0.0019*2500 + 215
= -4.75 + 215
= 210.25 degrees F

Hello!
To find the area of a trapezoid you use the equation
![A = \frac{a+b}{2} h](https://tex.z-dn.net/?f=%20A%20%3D%20%5Cfrac%7Ba%2Bb%7D%7B2%7D%20h)
A is area
h is height
a and b are the bases
Put in the values we know
![A = \frac{10+6}{2} *15](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cfrac%7B10%2B6%7D%7B2%7D%20%2A15)
Add
![A = \frac{16}{2} *15](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cfrac%7B16%7D%7B2%7D%20%2A15)
Divide
![A = 8 * 15](https://tex.z-dn.net/?f=A%20%3D%208%20%2A%2015)
Multiply
A = 120
The answer is 120cm squared
Hope this helps!
Answer:
2162.2 degrees Celsius
Step-by-step explanation:
Celsius (°C) = (Fahrenheit - 32) / 1.8
3924-32 = 3892
3982 / 1.8 = 2162.2222222222222222222222
Rounded is 2162.2
Answer:
B

Answer:
C
Step-by-step explanation:
Area of a circle is calculated by squaring the radius then multiplying by pi. Eight squared is sixty-four, then multiplied by pi you get 201.
