For this, just plug in 1.5 into the x variable of this function and solve as such:
<u>The height of the object was at 76 ft.</u>
The correct answer is 21.5
To find the length of the hypotenuse we must use Pythagoras' Theorem: c^2 = a^2 + b^2, where c is the hypotenuse and a and b are side lengths
c^2 = a^2 + b^2
c^2 = 12^2 + 35^2
c^2 = 144 + 1225
c^2 = 1369
c = 37 cm
D = discount on third shirt
c = total cost
Sales tax of 7.1% equates to 1.071
c = (Cost of 1st Shirt + Cost of 2nd Shirt + Cost of Third Shirt) * Sales Tax
c = (49.96 + 49.96 + (49.96 - d)) * 1.071
Since you didn't specify the discount on the third shirt, this is the best I can do for you.
The mean of the cost of the shirts would be c/3
