what is the value of
f−1(6)
a. 0.360
b. 1.242
c. 2.161
d. 2.312
f(x)=0.3(4)^x
f^-1(x) = ?
x = 0.3(4)^y
4^y = x/0.3
4^y = 6/0.3
4^y = 20
y = 2.161
Answer: x = 19 - 14
so 5 inch
Step-by-step explanation:
D;
supplementary angles sum up to 180°, so let's say we have two angles, a and b, a + b = 180, but we know that a is twice the measure of her partner, so a = 2b.
Answer:
60km
Step-by-step explanation:
75/10=x/8
Solve For X
75*8=600, 600/10=60
THEREFORE
75/10=60/8
You could ALSO Divide 75 by 10, get 7.5, and multiply THAT by 8, as the car is assumed to have constant gas usage
Answer:
60km
Step-by-step explanation:
Let x represent the required distance.
Since the quantity of petrol is directly proportional to the distance:
x : 75 = 8 : 10
i.e. =
x =
x = 60
∴ The distance is 60 km.
Hope this helps!!!
