The altitude of a triangle is 1cm shorter than the base. If the area of the triangle is 15cm2, calculate the altitude.

5 cm

Step-by-step explanation:

We khow that the altitude of this triangle is 1cm shorter than the base

that's a quadratic equation . Let's calculate the dicriminant .

Let Δ be the dicriminant

We have a negative value and a positive one

The altitude is a distance so it can't be negative

H= 5cm

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
