Let's go:

First: You must find the function roots. Function roots are values of y or f(x) when x equals zero.

After this, you use some values of x for find values of y.

And finally, you make the grafic with values founded.

I hope I helped you.

The area of circular garden is 615.44 feet2. What is the circumference of the garden? (Use 3.14 for .)

ella [17]

Answer:

B.)

87.92 feet

Step-by-step explanation:

Given:

Area of the circular garden $= 615.44 ft^2$

$\pi =3.14$

Finding the radius of the circle.

Area of the circle= $\pi r^2$

$615.44=\pi *r^2$

$r^2=\frac{615.44}{\pi } \\\\r^2=\frac{615.44}{3.14} \\r^2=196\\r=14 ft.$

Circumference of the garden:

$=2\pi r\\=2*3.14*14\\=87.92ft.$

the local store is having a sale on ground beef- $10 for 3 pounds. sylvia needs 12 pounds of meat to make 50 hamburgers. how muc

Rashid [163]

10/3 = x / 12.....$ 10 to 3 lbs = $ x to 12 lbs
cross multiply
3x = 120
x = 120/3
x = 40....so it is gonna cost Sylvia $ 40 for the meat.

she plans on making 50 burgers......40 ($ worth of meat) / 50 (burgers) =
0.8....so for each burger, the meat will cost 0.80 or 80 cents <==

A line passes through the point (-9, -3) and has a slope of 2.

tresset_1 [31]

Answer:

Step-by-step explanation:

hello :

note :

Use the point-slope formula.

y - y_1 = m(x - x_1) when : x_1= -9 y_1= -3

m= 2 (the slope)

an equation in the point-slope form is : y +3 = 2(x+9)

means : y+3 =2x +18

an equation in slope-intercept id : y=2x+15
