Answer:
Hi there!
Your answer is:
<em>8</em><em>.</em><em>6</em><em> </em><em>units</em>
Step-by-step explanation:
The distance formula is
√ ( (x2-x1)^2 + (y2-y1)^2 )
In your points:
A (-3, -2)
-3 is x1
-2 is y1
B (4, -7)
4 is x2
-7 is y2
Plug in to distance formula
√ ( 4-( -3))^2 + ( -7 - (-2))^2
√ (4+3)^2 + (-7+2)^2
√ (7^2) + ( -5)^2
√ 49 + 25
√ 74
This equals roughly 8.6 units!
Percent error = (estimate - real)/(real) * 100
percent error = (78.25 - 75.50)/(75.50) * 100
percent error = 3.6%
Answer:
It's not 0 I got it wrong.

Answer:
The graph relates the temperature change
y
(in degrees Fahrenheit) to the altitude change
x
(in thousands of feet).
a. Is the relationship proportional? Explain.
b. Write an equation of the line. Interpret the slope.
c. You are at the bottom of a mountain where the temperature is
74\F
. The top of the mountain is 5500 feet above you.
What is the temperature at the top of the mountain?
Step-by-step explanation:
Answer:
Yes . Divide by 10 for 10/20 to get 1/2.
10/10= 1
20/10= 2
10/20= 1/2
