Answer:

D, see attachment

Step-by-step explanation:

An equation with a squared symbol (²) will never be linear. You can also graph these lines to be sure.

The attachment shows each of these graphed.

Red line- A

Orange line- B

Green line- C

Purple line- D

The equation tan(55) = 15/b can be used to find the length of line AC.what is the length of line AC round to the nearest 10th 3.
Nadusha1986 [10]

Answer:

10.5 in

Step-by-step explanation:

Given

tan(55) = \frac{15}{b}

Required

Find length AC

The question is not detailed enough; so, I'll assume that b represents line AC.

Having said that;

We start by multiplying both sides by b

tan(55) = \frac{15}{b}

b * tan(55) = \frac{15}{b} * b

b * tan(55) =15

Divide both sides by tan(55)

\frac{b * tan(55)}{tan(55)} = \frac{15}{tan(55)}

b = \frac{15}{tan(55)}

Find tan(55)

b = \frac{15}{1.42814800674}

b = 10.5031130731

b = 10.5  <em>(Approximated)</em>

<em />

Length AC is 10.5

Point R is at (3, 1.3) and Point T is at (3, 2.4) on a coordinate grid. The distance between the two points is _____.
Bond [772]

Answer:

d = 1.1 units

Step-by-step explanation:

Since the x- coordinates of the 2 points are equal, both 3, then they lie on a vertical line. The distance between the 2 points is the difference in the y- coordinates, that is

d = | 2.4 - 1.3 | = | 1.1 | = 1.1 units
