Answer:

The equation of the new line is y=x+9  or  y-6=(x+3)

Step-by-step explanation:

step 1

Find out the slope of the line with x-intercept (3,0) and y intercept (0,3)

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{3-0}{0-3}=-1

step 2

Find the slope of the new line perpendicular to the given line

we know that

If two lines are perpendicular,then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

m_1*m_2=-1

we have

m_1=-1 ----> slope of the given line

so

m_2=1 ---> slope of the new line

step 3

Find the equation of the new line in point slope form

y-y_1=m(x-x_1)

we have

m=1

(x_1,y_1)=(-3,6)

substitute

y-6=(1)(x+3)

y-6=(x+3) ----> equation in point slope form

Convert to slope intercept form

y=mx+b

isolate the variable y

y=x+3+6

y=x+9

True [87]

Answer:

≈ 268 or 85.3π

Step-by-step explanation:

V = 1/3πr²h

V = 1/3 x 3.14 x 4² x 16

V ≈ 267.9467 or 268

also can be considered 85.3π

Find segment ET. Please and thank you​
Solnce55 [7]

Answer:

x=9

Step-by-step explanation:

Use the intersecting chord theorem:

RE*ET = UE*ES

Substitute values

21 (2x+2) = 30 (x+5)

Expand:

42x+42 = 30x + 150

transpose and simplify

42x-30x = 150 - 42

12x = 108

x = 9
