Answer:
x = 8
Step-by-step explanation:
log₅ (10x − 1) = log₅ (9x + 7)
10x − 1 = 9x + 7
x = 8
Step-by-step explanation:
Yes, one pair of opposite sides could measure 10 inches. and the other pair could measure 13 inches
Answer:
$697.09
Step-by-step explanation:
The computation of the investment after 3 years is shown below:
As we know that
Amount = Present value × (1 + rate)^number of years
= $600 × (1 + 0.05 ÷ 365)^365× 3
= $697.09
Hence, the investment after 3 years is $697.09
We simply used the above formula to determine the investment
Answer:
x = -2i and x = 2i
x = 3 and x = - 3
Step-by-step explanation:
x^4 - 5x^2 - 36 = 0
let u = x^2 and substitute
we have:
u^2 - 5u - 36 = 0
(u - 9)(u + 4) = 0
u = 9 and u = - 4
substitute back for u
x^2 = 9
x = 3 and x = - 3
x^2 = -4 -- i am going to assume you've learned imaginary numbers; otherwise, you cannot take the square root of a negative number.
x = -2i and x = 2i
Ma’am the answer is 8
Please finis
