Suppose you live 4.4 miles from a hill. From your home you see a plane directly above the hill. Your angle of elevation to the p

IrinaVladis [17]

█ Explanation █

Let's call the missing altitude 'x'.

✦ To find the plane's altitude, find the tan of 30 degrees. The side opposite is going to be x, while the side adjacent is going to be 4.4 miles.
✦ $Tan(30)= \frac{x}{4.4}$
✦ $5.7735= \frac{x}{4.4}$
✦ $x=4.4*.57735$
✦ $x=4.4*.55735$
✦ $x=2.54 mi$
✦ We usually write altitude in feet.

Answer: 2.54 * 5280 ~ 13,400 ft

I don’t understand the question above... pls give step by step explanation...

kirill115 [55]

Answer:

This is a linear function because the power of x is 1. Because of the +40 it's not a proportional relationship (they are in the form y = kx but the given equation is not) so the answer is the second option.

Solve on y: 3y+5/2y+1 = 2/6

Vedmedyk [2.9K]

Answer:

y = 4

Step-by-step explanation:

Move all terms containing y to the left, all other terms to the right. Add '-2y' to each side of the equation.

-5 + 3y + -2y = -1 + 2y + -2y

Combine like terms: 3y + -2y = 1y

-5 + 1y = -1 + 2y + -2y

Combine like terms: 2y + -2y = 0

-5 + 1y = -1 + 0

-5 + 1y = -1

Add '5' to each side of the equation.

-5 + 5 + 1y = -1 + 5

Combine like terms: -5 + 5 = 0

0 + 1y = -1 + 5

1y = -1 + 5

Combine like terms: -1 + 5 = 4

1y = 4

Divide each side by '1'.

y = 4

Simplifying

y = 4

Choose which function is represented by the graph

Viefleur [7K]

Given:

The graph of a function.

To find:

The function.

Solution:

From the given graph, it is clear that the graph intersect the x-axis at x=-4, -2, 1. It means -4, -2 and 1 are zeros of the given function graph.

If c is a zero of a function f(x), then (x-c) is a factor of f(x).

Using the above definition, we conclude that (x+4), (x+2) and (x-1) are the factors of given function. So,

$f(x)=(x+4)(x+2)(x-1)$

$f(x)=(x-1)(x+2)(x+4)$

Therefore, the correct option is A.
