The formula is
A=p (1+r)^t
A future value 572.6
P present value 560
T time 6/12 =1/2=0.5
R interest rate?
We need to solve for r
R=(A/p)^(1/t)-1
R=(572.6÷560)^(1÷0.5)−1
R=0.0455×100
R=4.55%
2y + 12 = -3x
Step-by-step explanation:
Divide y y by 1 1 . Divide 12 12 by 2 2 . Use the slope-intercept form to find the slope and y-intercept. The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept.
Ashton has saved: 60% of $120=(60/100)*$120=(60*$120)/100=$72
Ashton need to buy the bike=$120-$72=$48
He needs to buy the bike=$48
This is pretty simple once you get used to this
First set it equal to the original and the negative one
(>_) is the bigger and equal to part
4x+5>_45 or 4x+5>_-45
Then solve for x for both
4x>_40. 4x>_-50
X>_10 X>_-25/2
Given the function f (x) = 3x, find the value of f-1 (81).
For this case, the first thing you should do is rewrite the function.
We have then:
y = 3 ^ x
From here, we clear the value of x:
log3 (y) = log3 (3 ^ x)
log3 (y) = x
Then, we rewrite the function again:
f (x) ^ - 1 = log3 (x)
Now, we evaluate the inverse function for x = 81:
f (81) ^ - 1 = log3 (81)
f (x) ^ - 1 = 4
Answer:
the value of f-1 (81) is:
f (x) ^ - 1 = 4
