$2x^2 - x - 6 = 0$

$(2x - 3) (x + 2) = 0$

$2x - 3 = 0$

$2x = 3$

$x = \frac{3}{2}$

$x + 2 = 0$

$x = -2$

$x = \frac{3}{2} , 2$

Answer:

The answer to your question is VW = 2.2

Step-by-step explanation:

Data

angle = 63°

hypotenuse = ?

adjacent side = 1

Process

To solve this problem use trigonometric functions, the trigonometric function that relates the adjacent side and the hypotenuse is cosine.

cos α = $\frac{adjacent side}{hypotenuse}$

solve for hypotenuse

hypotenuse = $\frac{adjacent side}{cos \alpha}$

Substitution

hypotenuse = $\frac{1}{cos 63}$

Simplification

hypotenuse = $\frac{1}{0.45}$

Result

hypotenuse = 2.2

A man that is 6 feet tall casts a shadow 5 feet long. At the same time, a lamppost beside the man casts a shadow 25 feet long. H

Montano1993 [528]

Answer:

The answer to your question is: L = 30 ft

Step-by-step explanation:

Data

man = 6 ft

man shadow = 5 ft

lamppost shadow = 25 ft

lamppost height = ? = L

Process

$\frac{6}{5} = \frac{L}{25}$

$L = \frac{6 x 25}{5}$

$L = \frac{150}{5}$

L = 30 ft

One smartphone plan costs $52 per month for talk and messaging and $8 per gigabyte of data used each month. A second smartphone

valina [46]

Answer:

Both plans would cost $100 if 6 gigabytes of data are used.

Explanation:

From the question, the system of equation are correctly represented by using small letter c to represent the total cost in dollars for both equations as already assumed in the question as follows:

c = 52 + 8d ........................... (1)

c = 82 + 3d ........................... (2)

Since c is common to both, equations (1) and (2) can therefore be equated and d solved for as follows:

52 + 8d = 82 + 3d

8d - 3d = 82 - 52

5d = 30

d = 30 / 5

d = 6

Substituting d = 6 into equation (1), we have:

c = 52 + (8 * 6)

c = 52 + 48

c = 100

Since d = 6 and c = 100, it therefore implies that both plans would cost $100 if 6 gigabytes of data are used.
