Answer: option d.
Step-by-step explanation:
We have the function:
y = f(x) = x^2 - 1
The output is 99 when y = 99, and the input is x.
Then we need to solve:
y = 99 = x^2 - 1
for x.
99 = x^2 - 1
99 + 1 =x^2
100 = x^2
√100 = x
10 = x
The correct option is d, input equals 10.
K = F + 459.67
Subtract K on both sides:
0 = F - K + 459.67
Subtract F on both sides:
-F = -K + 459.67
Divide each term by -1 so that the variables are positive:
F = K - 459.67
Answer:
FV= $12,450
Step-by-step explanation:
Giving the following information:
David invests $10,000 in a savings account that pays 3.5% simple interest.
<u>To calculate the future value, we need to use the following formula.</u>
FV= PV*(1+i*n)
n= 7
i= 0.035
PV= 10,000
FV= 10,000*(1+0.035*7)
FV= $12,450
Answer:
x = 7.8
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + 2^2 = c^2
16 + 4 = c^2
c^2 = 20
c = 4.5
a^2 + b^2 = c^2
a^2 + 4.5^2 = 9^2
a^2 + 20.25 = 81
a^2 = 81 - 20.25
a^2 = 60.75
a = 7.8
Answer:A
1/48 = 102/ ???
1 × 102 = 102
48 × 102 = 4896 mm, or 4.896 m
B
1 inch = 25.4 mm
1/48 = 1 and one fourth in/54 in
54 ÷ 1 1/4 = 43
43 ≠ 48
