Find the midpoint between 3pi and pi
Explanation:
We apply the midpoint formula like so
C = (A+B)/2
C = (3pi+pi)/2
C = (4pi)/2
C = 2pi
This means 2pi is exactly halfway between pi and 3pi
This is similar to saying that 2 is halfway between 1 and 3. Think of the "pi" as "1pi", and we're effectively just looking at the coefficients.
Choose each correct statement.
1. Sin A = b/c
2. Cos A = b/c
3. Tan A = b/8
4. M
5. m
6. Sin B= 8/c
7. Cos B = b/c
8. Tan B = b/8
9. Sin A = 8/c
10. Tan A =8/b
11. Sin B = b/c
12. Sin A = Cos A
13. Sin A = Cos B
Answer:
Step-by-step explanation:
Sin(A) = 8/c Not correct.Cos(A) = b / c CorrectTan(A) = b / 8 Correct and Makes no sense to meSin(B)= b/c CorrectCos(B) = 8/c Not correctTan(B) = b/8 CorrectSee (A) Not CorrectTan(A) See 3 Not CorrectSee 6Sin(A)=Cos(A) Not correctSin(A) =Cos(B) Correct2,3,5,6, 8,11,13 Are correct.

2(x-1)(x+2)[tex]2(x-1)(x+2)[/tex]
[tex]\boxed{\underline{\bf \: ANSWER}}[/tex]
I assume the following equation is the question you asked.
[tex] \rightarrow \sf \: 2(x - 1)(x + 2)[/tex]
If yes, these are the following are the steps to reach your answer :-
[tex]\sf \: 2(x - 1)(x + 2)[/tex]
Use the distributive property to multiply 2 by x - 1.
[tex] \sf \: \left(2x-2\right)\left(x+2\right) [/tex]
Apply the distributive property by multiplying each term of 2x - 2 by each term of x + 2.
[tex] \sf \: 2x^{2}+4x-2x-4 [/tex]
Combine 4x and - 2x to get 2x.
[tex] \boxed{ \bf \: 2x^{2}+2x-4 }[/tex]
=> The answer will be 2x² + 2x - 4.

Given that measure angle AEB equals 4x+1 and measure angle CED equals 3x, determine the missing measures.
[tex]\\ \rm{:}\dashrightarrow 4x+1=3x[/tex]
[tex]\\ \rm{:}\dashrightarrow 4x-3x=1[/tex]
[tex]\\ \rm{:}\dashrightarrow x=1[/tex]
Now
[tex]\\ \rm{:}\dashrightarrow 3x=3(1)=3[/tex]
[tex]\\ \rm{:}\dashrightarrow 4x+1=4(1)+1=5[/tex]
Answer:
AEB = -3
CED = -3
Step-by-step explanation:
We can make an equation and solve for x.
4x + 1 = 3x
~Subtract 1 to both sides
4x = 3x - 1
~Subtract 3x to both sides
x = -1
Now we can substitute that value of x into both angles.
4(-1) + 1 = -4 + 1 = -3
3(-1) = -3
Best of Luck!

Answer:
So the answer is H
Step-by-step explanation:
They could be situated as
x y z
in which case xy 5 and yz = 3
The total would be 8.
if they are situated like this
x z y
then xy = 5 and yz = 3 but its going the opposite way.
5 - 3 = 2

Evaluate the function rule for the given value.
f(x)= 3× for x= -4
A. –12
B. 1/81
C. –64
D. 1/243
Answer:
B. 1/81
Step-by-step explanation:
f(-4) = 3(-4)
f(-4) = -12
Hope that helps.
-12,1/243,-64 or 1/81
1/81 would be the correct answer to the equation hope this helps
evaluate the function rule for the given value.

Rotate ΔCAR if C(-1,-4), A(2,3), R(-3,-2) 180° about the origin
Answer:
C(1,4) , A(-2,-3), R (3,2)
Step-by-step explanation:
the formula thing for rotating 180° about the origin is (x,y) -> (-x,-y)
this doesn't mean make the number negative, but make it the opposite if that makes sense
e.g. F(2,-4) -> F(-2,4)

4. Your first six-month auto insurance premium was $729.00. Based on your good
driving record, your renewal premium is $648.81. What percent decrease did you see
in your premium? (2 points)
I
Answer: 11%
Step-by-step explanation:
729-648.81=80.10
What percent is 80.10 of 729
%/100 = is/of (this may help you)
X/100 = 80.10/729 (cross multiplication)
(80.19*100)/729 =

Answer:
- 3x² + x + 5
Step-by-step explanation:
- 2x² + 4x + 5 - (x² + 3x) ← distribute by - 1
= - 2x² + 4x + 5 - x² - 3x ← collect like terms
= - 3x² + x + 5
Hi
Golden rule to know by heart : you can only add or substract element of the same kind.
so X^2 with X^2 , X with X , numbers with numbers...
exemple : 2X^2 +3X^2 = 5X^2
but 5X^2 -3X remains that way as 5X^2 is a " X^2" and " 3X" is a " X" so I can't substract two elements of different kind.
Now you have to translate what is ask of you into a calculus.
so : you have
A ) ( 2x^2+4x +5) - ( x^2+3x)
Math is a sport of the mind. You will only progress and become stronger if you train.
So I let you have a shot. beware of signs rules. If you still have trouble, ask in comment section..

Find the exact value of cos A in simplest radical form.
X= (2a+5)² Y= (a-3)²
X+Y??
Answer:
X = (2a + 5)^2 = 4a^2 + 20a + 25
Y = (a-3)^2 = a^2 - 6a + 9
4a^2 + 20a + 25 + a^2 - 6a + 9
X + Y = 5a^2 + 14a + 34
