Answer:
6.25π cm²
Step-by-step explanation:
pi = π
Circumference = 5πcm
Now first we should find radius(r)
2πr = 5π cm
pie will be cancelled and we get here
r = 5/ 2 cm
Therefore r = 2.5 cm
Now
Area (A) = πr²
= π * 2.5²
= 6.25π cm²
Answer:
k = 2
Step-by-step explanation:
the dilation k is the scale factor. A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object. To find the scale factor k, we will compare the original points with their transformation
Point R is at (-1,2), and R' is at (-2,4).
divide the ys: 4/2 =2
divide the xs: -2/-1 =2
therefore the scale factor is 2
Answer: The answer is
22x + 16y
Step-by-step explanation: U gotta sum each letter with the same letter. For example in your assignment you have to sum 8x + 7x + 8x + 3x bc all the numbers have letter and the same goes for y u gotta sum 7y + 7y + y + y
Hope u understand :))
Answer:
D, 225
Step-by-step explanation:
Because this equation already has a1, it's useless to test with that, so instead solve for a2.
You would have a2 - 5a1, which would get you a2 = 5(9) because we already know what a1 is, which is 9. a2 = 45
Now we have a2, which is 45, so now we solve for a3
We would have a3 = 5a2 = a3 = 5(45) which is 225 which is a3
Also thanks for the fat 18 points dude, you really put 36 points into this one big value hope this one helped you a lot
Answer:
C: 4
Step-by-step explanation:
4x+3=6x-5
Add five to both sides
4x+8=6x
Subtract both sides by 4x
8=2x
Divide both sides by 2
X=4
