Answer:

10cm

Step-by-step explanation:

find the diameter of the circumference of 5cm:

d= c÷3.14

=5cm÷3.14

=1.6cm

Double 1.6cm:

1.6×2= 3.2

Find the new cicumference:

c= 3.14×d

= 3.14×3.2

= 10cm

Rewrite the point-slope equation in slope-intercept form: y - 3 = 2(x + 4)

Olin [163]

Answer:

y = 2x + 11

Step-by-step explanation:

y - 3 = 2(x + 4)

y - 3 = 2*x + 2*4

y -3 = 2x + 8

y = 2x + 8 +3

y = 2x + 11

What is the area of this trapezoid?

Pie

Area of a Trapezoid, A = [(a+b)/2] · h

Where,

a and b are the respective bases of the trapezoid

h is the height of the trapezoid

a = 10

b = 7 + 10 + 10 = 24

h = 9

A = [(a+b)/2] · h

A = [(10 + 24)/2] · 9

A = [(34)/2] * 9

A = 17 * 9

A = 153 Units²

Write an equation in slope-intercept form for the line that passes through (5,0) and is perpendicular to the line described by y

natta225 [31]

For this case we have to;

We have that an equation in slope-intercept form is given by:

$y = mx + b$

Where:

m is the slope

b is the cut point with the y axis

Also, by definition, two lines are perpendicular when the product of their slopes is -1. That is: $m_ {1} * m_ {2} = - 1$

We have the line as data: $y_ {1} = \frac {-5} {2} x + 6$

Then $m_ {1} = \frac {-5} {2}$

We found $m_ {2}$ :

$m_ {1} * m_ {2} = - 1$

$\frac {-5} {2} * m_ {2} = - 1$

$m_ {2} = \frac {-1} {(\frac {-5} {2})}$

$m_ {2} = \frac {(2) (- 1)} {(- 5) (1)}$

$m_ {2} = \frac {2} {5}$

Thus, $y_ {2} = \frac {2} {5} x_ {2} + b_ {2}$

We must find $b_ {2}$ :

We know that $y_ {2}$ passes through the point $(x_ {2}, y_ {2}) = (5,0)$

We substitute the point in the equation of $y_ {2}$ :

$0 = \frac {2} {5} (5) + b_ {2}\\0 = 2 + b_ {2}\\b_ {2} = - 2$

Thus, $y_ {2} = \frac {2} {5} x_ {2} -2$

Then the equation in slope-intercept for the line that passes through (5,0) and is perpendicular to the line described by $y_ {1} = \frac {-5} {2} x_{1} + 6$ is: $y_ {2} = \frac {2} {5} x_ {2} -2$

Answer:

$y_ {2} = \frac {2} {5} x_ {2} -2$

Can you explain this?

zvonat [6]

Answer:

I know y intercept is when the line first touches the Y line which is the vertical line.
