1. What is the circumference of a circle with a radius of 3? (1 point)

4vir4ik [10]

1. $6 \pi$
This is because
$c= \pi d \\ 
c= 6 \pi$

2. $9 \pi$
because
$A= \pi r^{2} \\ 
A = \pi (3)^{2} \\ 
A = 9 \pi$

3. $4 \pi$
$C= \pi d \\ 
C= 4 \pi$

4. $4 \pi$
$A = \pi r^{2} \\ A = \pi (2)^{2} \\ A = 4 \pi$

Can't really answer the last 2 w/o the figures

Point A has the coordinates (2,2). What are the coordinates of its image point if it is translated 2 units up and 5 units to the

Marysya12 [62]

A translation of 2 units up will increase the y coordinate by 2 units and a translation by 5 units to the left will decrease the x coordinate by 5. Hence after these translations point (2,2) becomes

(2 - 5 , 2 + 2) = (-3,4) 

When point (-3,4) is reflected in the x axis, its y coordinate changes sign and point (-3 ,4) becomes

(-3,-4)

30. Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5

tamaranim1 [39]

Equation in point-slope form is $y-9=4/5(x+7)$

Option C is correct.

Step-by-step explanation:

We need to Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5

The formula used for point-slope form is:

$y-y_1=m(x-x_1)$

We are given slope m = 4/5

Point (-7,9) where x₁ = -7 and y₁ = 9

Putting values in the formula:

$y-y_1=m(x-x_1)\\y-9=4/5(x-(-7))\\y-9=4/5(x+7)$

So, equation in point-slope form is $y-9=4/5(x+7)$

Option C is correct.
