Answer:
Gaby scored 27 points.
Step-by-step explanation:
First, you have to find 3/5 of both of the numbers.
What I did was I found 1/5 of each number and multiplied it by 3.
25/5=5, so 1/5 of 25 is 5. 5(3)= 15, so Gaby scored 15 points in the first game.
20/5= 4, so 1/5 of 20 is 4. 4(3)= 12, so Gaby scored 12 points in the second game.
Finally, add 15+12, which equals 27 :).
Hello,
r=5(1+cos t)
r'=5(-sin t)
r²+r'²= 25[(1+cos t)²+(-sin t)²]=50(1-cos t)=50 sin² (t/2)
Between 0 and π, sin x>0 ==>|sin x|=sin x
![l= 2*5* \int\limits^{\pi}_0{sin( \frac{t}{2} )} \, dt= 5[-cos (t/2)]_0^{\pi}\\\\ =5(0+1)=5](https://tex.z-dn.net/?f=l%3D%202%2A5%2A%20%5Cint%5Climits%5E%7B%5Cpi%7D_0%7Bsin%28%20%5Cfrac%7Bt%7D%7B2%7D%20%29%7D%20%5C%2C%20dt%3D%205%5B-cos%20%28t%2F2%29%5D_0%5E%7B%5Cpi%7D%5C%5C%5C%5C%0A%3D5%280%2B1%29%3D5)
Here is the method but i may have make some mistakes.
Answer:
The center is (0,0) and the radius is 4
Step-by-step explanation:
x^2+y^2=16.
The equation of a circle can be written in the form
(x-h)^2+(y-k)^2=r^2 where ( h,k) is the center and r is the radius
(x-0)^2+(y-0)^2=4^2
The center is (0,0) and the radius is 4
Answer:
The most reasonable answer would likely be the first.
"When a pair of parallel lines is intersected by a third line, the alternate exterior angles are congruent."
Step-by-step explanation:
Answer:
-8(3x-2y)
Step-by-step explanation:
Factor out each number because 8 times 3 equals 24
And -2 times -8 is 16
