Answer:
r = 40/π exact answer
r = 12.7 decimal approximation
Step-by-step explanation:
arc length formula
s = (∅/360) * 2πr
s = (∅/180) * πr
--------------------------------
Plug in the givens
10 = (45/180) * πr
10 = .25πr
Divide both sides by .25
40 = πr
divide both sides by π
40/π = r
r = 40/π exact answer
r = 40/3.14
r = 12.7 decimal approximation
Answer:
x + 8 + -8x−24/x^2 + 5
Step-by-step explanation:
Divide using polynomial division.
Answer:
B) 10
Step-by-step explanation:
∠IJA= ∠HJA
ΔIJA has twice smaller side opposite ∠J than ∠A
Similarly
ΔHLA side 5 opposite ∠J,
So x/5= 20/10 ⇒ x= 5*2= 10
Answer choice is B) 10
Answer:
x < -5 or x > 2 , and because or can be in either, doesn't and literally can't be in both
Step-by-step explanation:
When you simplify 2x-2>12, it's like an algebra problem where you just add 2 to both sides and then divide by 2. Same for 2x+3>7, except you subtract 3 and then divide by 2
Answer:
<u>Part A:</u> (0,0)
<u>Part B:</u>
(1, -1) go over one to the right and down one
(-1, 1.25) go over one to the left and up 1.25
(-2, 3/4) go over two to the left and up .75
Step-by-step explanation:
<u>Part A:</u> the origin of a graph is always (0,0)
<u>Part B:</u>
(x, y) the first number is your x which goes left and right. if the number is negative you go left and if the number is positive you go right. the second number is your y which goes up and down. if the number is negative you go down and if the number is positive you go up
