Answer:
Circumference = 42
Area = 147 to the power of 2
Step-by-step explanation:
7x2=14 diameter
3x14=42 circumference
Area = 7x7x3 =147 to the power of 2
Answer:
3.
equation = 
Using:
or 
or
7^2 + 12^2 = c^2
49 + 144 = c^2
c^2 = 193
missing length = 13.9 inches
4. equation = 
Using:
or
24^2 + 32^2 = c^2
reduce to:
8 multiplied by everything:
3^2 + 4^2 = c^2
Since we know 3,4,5 is a Pythagorean triple, we can use this to find c.
Since c must be 5, we multiply by 8 since we divided by 8 earlier to get the 3,4,5 and get 40.
missing length = 40 inches
(-2,15)(9,-18)
slope = (-18 - 15) / (9 - (-2) = -33/11 = -3
There can be 2 answers to this question....
point slope form : y - y1 = m(x - x1)
(1) using points (-2,15)...
y - 15 = -3(x + 2) <== one possible answer
(2) using points (9,-18)
y + 18 = -3(x - 9) <== another possible answer
Step-by-step explanation:
2x+30+x+72°=180
3x+30=180°-72°
3x+30=108°
9514 1404 393
Answer:
4.5
Step-by-step explanation:
The value of x that makes f(x) = -3 is ...
4/3x -9 = -3
4/3x = 6 . . . . . . add 9
x = 6(3/4) = 18/4 = 9/2 = 4.5 . . . . multiply by 3/4
f^-1(-3) = 4.5
