If you look at the image you can see that it says “x - 2 is greater than/equal to 0
Answer:
A. About 4,900 ft
Step-by-step explanation:
We want h such that ...
5 = 10·ln(h) -80
8.5 = ln(h) . . . . . . . add 80, divide by 10
e^8.5 = h ≈ 4914.8 . . . . take the antilog
h ≈ 4900 . . . . feet
Answer:
5*7^2 is the other way to write the question
Step-by-step explanation:
245: 7 * 7 * 5
You could write it as 7^2 * 5
Method:
You know that 5 divides into 245
245: 5 * 49 49 factors into 7 * 7
So the result is 5 * 7 * 7
To solve this system of equations, start by plugging your equation for x wherever x appears in your second equation, giving you (y-3)+3y=13. Now, combine like terms, (y-3)+3y=13 => 4y-3=13, solve for y by adding 3, 4y-3=12 => 4y=16, divide by 4, 4y=16 => y=4. Now that you have your y value, plug it into the equation for x to get the x value, x=y-3=4-3=1. This makes your solution (1,4), answer choice A
Answer:
$482.11 in interest
Step-by-step explanation:
Use the compound amount formula. Calculate the compound amount and then subtract the principle to find the amount of interest earned.
A = P(1 + r)^t, where r is the interest rate as a decimal fraction
This becomes:
A = $575(1 + 0.07)^9, or A = $1057.11.
Subtracting the principal: A - P: $1057.11 - $575 = $402.11
