Answer:
r = 0.16
Step-by-step explanation:
C = 2·π·r
1 = 2·π·r
1/2 = π·r
0.5 = π·r
0.5 / 3.14 = r
0.16 = r

Graph the equation y = -x^2+ 8x – 15 on the accompanying set of axes. You must plot 5 points including the roots and the vertex. Using the graph, determine the roots of the equation –x^2 + 8x – 15 = 0.
Answer:
Graph below
Step-by-step explanation:
Graph of the Quadratic Function
We are given the function:
[tex]y=f(x)=-x^2+8x-15[/tex]
Select 5 values of x={2,3,4,5,6}
And calculate the corresponding values of y:
[tex]f(2)=-2^2+8*2-15=-4+16-15=-3[/tex]
[tex]f(3)=-3^2+8*3-15=-9+24-15=0[/tex]
[tex]f(4)=-4^2+8*4-15=-16+32-15=1[/tex]
[tex]f(5)=-5^2+8*5-15=-25+40-15=0[/tex]
[tex]f(6)=-6^2+8*6-15=-36+48-15=-3[/tex]
We have obtained the points
(2,-3) (3,0) (4,1) (5,0) (6,-3)
Now we plot them in the graph below.
It can be noted three remarkable points:
The vertex is located at (4,1)The roots are located at (3,0) and (5,0)The roots of the equation
[tex]-x^2+8x-15=0[/tex]
Are x=3 and x=5.

Help me please I don't know how to solve this problem.
2x + y = 11
3x - y = 4
Answer:
[tex]x=3,y=5[/tex]Step-by-step explanation:
Add the equations together and solve for x.
[tex](2x + y )+ (3x - y) = 11 + 4[/tex]
[tex]5x=15[/tex]
[tex]x=3[/tex]
Use equation [tex]2x+y=11[/tex] to solve for y.
[tex]2(3) +y=11[/tex]
[tex]6+y=11[/tex]
[tex]y=11-6[/tex]
[tex]y=5[/tex]

Explain how to isolate the variable in the equation−2/3+7=15. solve for n
Answer:
n = - 0.0833
Step-by-step explanation:
Given expression
[tex]\frac{-2}{3n } +7 = 15[/tex]
Cross multiplication , we get
[tex]\frac{-2}{3n } = 15 -7[/tex]
[tex]-2 = 8 X 3 n[/tex]
⇒ [tex]\frac{-2}{24} = n[/tex]
n = - 0.0833
how do i find thhe greatest common factor?
Answer:
lets say you needed to find the greates comon factor of 20 and 5, you need to find the closest number they both go into, so 20. or if it was 3 and 10 it would be 30 because it is the closest thing they both go into, i hope i am right i am so sorry if i am wrong.

Answer:
x = 10, y = [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
The opposite sides of a parallelogram are congruent.
For LMNO to be a parallelogram then
ON = LM and OL = NM, that is
ON = LM
7x - 6 = 6x + 4 ( subtract 6x from both sides )
x - 6 = 4 ( add 6 to both sides )
x = 10 , then
NM = x - 9 = 10 - 9 = 1 and
OL = NM , that is
3y - 3 = 1 ( add 3 to both sides )
3y = 4 ( divide both sides by 3 )
y = [tex]\frac{4}{3}[/tex]

The length of DE is
units.
Answer:
10
Step-by-step explanation:
use the distance formula. (-4-4)^2 gives 64. (2+4)^2 gives 36. add them to get 100/ square root of 100 is 10.
Kate has 48 softballs. She wants to divide them evenly among b softball bags. Which expression represents how many softballs she should put into each bag?
Answer:
Softballs = (48/b)
Step-by-step explanation:
Given that,
Total number of softballs = 48
She wants to divide them evenly among b softball bags.
We need to find an expression that represents how many softballs she should put into each bag.
As it is dividing among b softball, it means we divide 48 and b. So,
[tex]s=\dfrac{48}{b}[/tex]
Hence, the required expression is (48/b).

Steps:Multiply both sides by 8
8a———-=8 · 8
5+3
Simplify:a=64B)
3b/7 - 1 = 5
Add 1 in both sides
3b/7 - 1 + 1 = 5 + 1
3b/7 = 6
Multiply both sides by 7 and then divide by 3.
