Rational number are equivalent to ratios of two integers ( the denomitator being non-zero ). A ratio is a relationship between two set of values. For example, the ratio of the circumference of a circle to its diameter is pi, which is not a rational number.

Write an equation in point-slope form and

NikAS [45]

Answer:

y-3 = 4(x+2) point slope form

y = 4x+11 slope intercept form

Step-by-step explanation:

Since we have a point and a slope, we will start with point slope form

y-y1 = m(x-x1)

y-3 = 4(x--2)

y-3 = 4(x+2)

This is point slope form

Distribute

y-3 = 4x+8

Add 3 to each side

y-3+3 = 4x+8+3

y = 4x+11

slope intercept form

What is the value of x in the triangle?

Blizzard [7]

Answer:

x = 23.78

Step-by-step explanation:

From the information given, we can construct the triangle shown in the attached picture.

With respect to the angle 18, we have the hypotenuse (25) and we want to know the adjacent side (x). Thus, what trigonometric ratio relates adjacent to hypotenuse? COSINE! Thus we can set-up the ratio shown below and compute x.

$Cos (18)=\frac{x}{25}\\x=25*Cos(18)\\=23.78$
