Answer: 5²⁻⁵
<u>Step-by-step explanation:</u>


The answer is $84.29
Let the number of minutes be x.
$35.99 is fixed price and does not depend on the number of minutes x. Each minute costs $0.21 so it depends on x and we have 0.21x in the function. However, 250 minutes are already included and should not be included in x. Therefore, the function that represents the monthly cost looks like this:
f(x) = 35.99 + 0.21 * (x - 250)
Now, let's calculate for x = 480 minutes:
f(480) = 35.99 + 0.21 * (480 - 250)
f(480) = 35.99 + 0.21 * 230
f(480) = 35.99 + 48.30
f(480) = 84.29
The expression using radical notation 27 2/3
The first one pretty sure :))))
Answers :
BC = 17.1
Angle B = 6.7°
Angle C = 83.3°
To find side BC, you use pythagorean’s theorem, which is a^2 + b^2 = c^2
This gives you 289 + 4 = 293, and you find the square root, which is 17.1.
To find the angle measures you can use tangent, which is opposite sides over adjacent sides. You plug these values into a calculator.
b = tan 2/17 = 6.7°
c = tan 17/2 = 83.3°
