Answer:
±2sqrt(10) = x
Step-by-step explanation:
40 - x^2 = 0
Add x^2 to each side
40 - x^2+x^2 = x^2
40 = x^2
Take the square root of each side
sqrt(40) = sqrt(x^2)
±sqrt(40) = x
±sqrt(4) sqrt(10) = x
±2sqrt(10) = x
Answer:
C = 12.6 inches
Step-by-step explanation:
The circumference of a circle is given by
C = 2* pi*r
Using 3.14 for pi and 2 for r
C = 2 * 3.14 *2
C =12.56
To the nearest tenth
C = 12.6 inches
Answer:
16
Step-by-step explanation:
f(-2)=4-3(-2)*2
f(-2)=4-3(-4)
f(-2)=4+12
f(-2)=16
