I think the answer is 2,612.48 because if you multiply the radius, 80 by itself you get 640. Then if you multiply 640 by 3.14 and then multiply the product by 1.3 you get 2,612.48.

Find f(-5) f(x) -4x + 3
Fiesta28 [93]

Answer:

if f(x)= -4x+3

f(-5)= 23

Step-by-step explanation:

first you substitute x for -5

f(-5)= -4(-5)+3

then you multiply

-4(-5)

f(-5)=20+3

you get the positive 20 because negative times negative equals positive

then you just add the rest (20+3) which will give you your answer

f(-5)= 23

Write an equation for your trend line?
Soloha48 [4]
Find two points on the graph that the line crosses through almost perfectly. It looks like (1,10) and (9,1) will do.

Use them to compute the slope:
m = (1 - 10) / (9 - 1)
= -9/8

Then set up the "point-slope form":
y - y0 = m * (x - x0)

You choose some point (x0, y0) that the line crosses through. We already know the line passes through (1,10) pretty well, so let's use that.

x0 = 1
y0 = 10

Now finish plugging into the equation:
y - 10 = -9/8 * (x - 1)

The above equation will work fine for an answer, but let's go a step further and solve for y.

y - 10 = -9/8x + 9/8
y = -9/8x + 9/8 + 10
y = -9/8x + 9/8 + 80/8
y = -9/8x + (9 + 80)/8
y = -9/8x + 89/8

Un número desconocido es multiplicado por 11 y a este resultado se le resta 24. El resultado de esta operación es 86. Escribe en
kicyunya [14]

Answer: The number is 10.

Step-by-step explanation:

Let x be the required number.

Given: 11 is multiplied to the number then 24 is subtracted from that and the result is 86.

The mathematical statement for the given situation,

11x -24 = 86

To solve the equation, Add 24 on  both sides , we get

11x - 24 +24 = 86+24

⇒ 11x = 110

Divide both sides by 11, we get

x = 10

hence, the number is 10.
