Answer:
0.64π rad
Step-by-step explanation:
The formula for calculating the length of an arc is expressed as;
length of an arc = theta/360 * 2πr
r is the radius = 13 feet
arc length = 26feet
Substitute
26 = theta/360 * 2(3.14)(13)
26 = 81.64 theta/360
81.64 theta = 26 * 360
81.64 theta = 9360
theta = 9360/81.64
theta = 114.64
Hence the radian measure is 114.64/180 π = 0.64π rad

yo can someone please help and fast PLEASE
Answer:
It's incorrect because the equation is solve incorrectly the anwer is r= -4
Step-by-step explanation:
Add 4r4r to both sides.
-3r+9+4r=5
−3r+9+4r=5
2 Simplify -3r+9+4r−3r+9+4r to r+9r+9.
r+9=5
r+9=5
3 Subtract 99 from both sides.
r=5-9
r=5−9
4 Simplify 5-95−9 to -4−4.
r=-4
r=−4

-2(x-3)+4x = -(-x+1) SOLVE EQUATION AND SHOW STEPS ...NEED ANSWER NOW
Answer:
x=-7
Step-by-step explanation:
-2(x−3)+4x=−(−x+1)
Step 1: Simplify both sides of the equation.
−2(x−3)+4x=−(−x+1)
−2)(x)+(−2)(−3)+4x=x+−1(Distribute)
−2x+6+4x=x+−1
(−2x+4x)+(6)=x−1(Combine Like Terms)
2x+6=x−1
2x+6=x−1
Step 2: Subtract x from both sides.
2x+6−x=x−1−x
x+6=−1
Step 3: Subtract 6 from both sides.
x+6−6=−1−6
x=-7

The vertex form of the equation of a parabola is y = 5(x-3)2 - 6.
What is the standard form of the equation?
9514 1404 393
Answer:
y = 5x² -30x +39
Step-by-step explanation:
Multiply it out and collect terms.
y = 5(x -3)² -6
y = 5(x² -6x +9) -6 . . . . . expand the square
y = 5x² -30x +45 -6 . . . . use the distributive property
y = 5x² -30x +39 . . . . . . collect terms
_____
The expansion of a binomial square is ...
(a +b)² = a² + 2ab + b²
In this problem, we have a=x, b=-3.
Answer:
y = 5x² -30x +39

The first night in a hotel costs 40 dollars. All additional nights cost 27 dollars. How many nights did we stay
at this hotel if the total bill was 148 dollars?
Answer:
5
Step-by-step explanation:
First, you would want to subtract the first nights cost from the bill, which you would get 108. And then you would want to divide 108 by how much it costs to stay additional night, so 108 divided by 27 = 4. But you have to remember to add the first night you stayed so it would be 5. I hope this helps :)
Answer:
4 nights
Step-by-step explanation:
148-40=108
108÷27=4
So, you spent 4 nights at the hotel.

if I have a 53 in class what grade do I need to get in a test to get a 90
Answer:
you would have to make 100s on at least 5 tests or assignments
Step-by-step explanation:
Answer:
It depends.
Step-by-step explanation:
Basically, your grade is a result of the average score on all of your assignments and even attendance. Average is all scores added together, divided by the number of scores. Also, depending on the teacher, some scores weigh more, meaning a test counts for more than a worksheet does.
Also, even if you get a 100 on your test, you'll unlikely get a 90. :(
