Answer:
It is a).
Step-by-step explanation:
The rule for change of base of a log is:
logb x = = loga x / loga b
So we have
log6 5 = log4 5 / log4 6.
Answer:
x = 3
Step-by-step explanation:
The translation rule (x + 10, y - 6) means add 10 to the original x- coordinate and subtract 6 from the original y- coordinate, that is
G(- 7, 4) → G'(- 7 + 10, 4 - 6) → G'(3, - 2)
Answer:
43
Step-by-step explanation:
3x + 10 = 5x - 12
10 = 2x - 12
22 = 2x
x = 11
check:
33 + 10 = 55 - 12
43 = 43
correct
x = 11 so bring this into 3x + 10
we get 43
Answer:
140.74
Step-by-step explanation:
1.area of right triangle
1/2*b*h=1/2*20*18=180
2.area of semi circle
1/2*pi*r^2=1/2*pi*5^2=39.26
r= d/2
180-39.26=140.74
