PLEASE HELP. WILL MARK BRAINLIEST.

Mathematics
1 answer:
Alina [70]3 years ago

Answer:

y = x² + 6x + 8

Step-by-step explanation:

The zeros ( x- intercepts ) of the graph are x = - 4 and x = - 2, thus

the factors are (x + 4) and (x + 2) and the function is the product of the factors.

y = a(x + 4)(x + 2) ← a is a multiplier

To find a substitute (0, 8 ) the y- intercept into the equation

8 = a(0 + 4)(0 + 2) = a(4)(2) = 8a ( divide both sides by 8 )

a = 1, thus

y = (x + 4)(x + 2) ← expand using FOIL

  = x² + 6x + 8

Sin A =  opp/hyp = 4/5

Cos A = adj/hyp =  3/5

Tan A = opp/adj =  4/3

Cos 27 = 0.8910065...  --> 0.89

You can just plug that into your graphing calculator, just make sure the degree mode is on.

A construction company is building the house shown below. They need to use a scale
Svetllana [295]

The height of the building is calculated by representing 1 inch as 8 feet. The final building has a height of 20 feet.

<h3>What is scaling?</h3>

Scaling is the increase or decrease in the height of an object by a scale factor k.

Given that the scale used is:

1 inch = 8 feet. Hence:

Since the height of the building is 2.5 in, hence:

Height of the final building = 2.5 in * 8 ft per 1 in = 20 feet

The height of the final building is 20 feet.
