Those two angles are congruent(corresponding), so we can set these equal to each other.
19x+3=21x-3
-2x=-6
x=3
F(-1)=1-2=-1
f(4)=16-8-4=4
A(x)=f(4)-f(-1)/4-(-1)
A(x)=4-1/4+1=3/5
Answer:
√(A/4π) = r
Step-by-step explanation:
A = 4πr²
r² = A/4π
r = √(A/4π)
Answer:
12/7 hours
Step-by-step explanation:
First find the rate for hour for the two. For Lianne she can do 1/3 of the job per hour. For Julie she can do 1/4 of the job per hour.
Adding them together, 1/3+1/4= 7/12.
This 7/12 means that working together they can finish 7/12 of a job in an hour. We can use the speed*time=distance formula here and see that
7/12 * time = 1 job done
time = 12/7 hours.
Answer:
C)12 x 108 has the closest value.
Step-by-step explanation:
Firstly, (7 x 108) + (5 x 105) is equal to 756 + 525 which is equal to 1281.
A)7 x 108= 756
B)12 x 1013= 12156
C)12 x 108=1296
D)7 x 1013=7091
