y ≈ 4.4 cm

Step-by-step explanation:

The image is uploaded below.  From the image below you can deduce that the triangle formed is a right angle triangle. The triangle has a height of 12 cm and the base is what we are ask to find.

A right angle triangle has an opposite side , a hypotenuse and an adjacent side. From the right angle triangle below the adjacent side is y cm, the opposite side is 12 cm and the hypotenuse is x cm. The angle between the hypotenuse and the adjacent side is 70°.

Using SOHCAHTOA principle

tan 70° = opposite /adjacent

tan 70° = opposite /adjacent

tan 70° = 12/y

cross multiply

y tan 70° = 12

y = 12/tan 70°

y = 12/2.74747741945

y = 4.36764281119

y ≈ 4.4 cm

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
