Hope this is a clear description
Answer:
RP=15
x=14
Step-by-step explanation:
ΔJKL≅ΔPQR so JK=PQ, KL=QR, and JL=PR.
KL=3y-2 and QR=22
So, 3y-2=22 and 3y=24 and y=8
Now, that we know y=8 we can plug it in 2y-1 to find RP
2(8)-1=16-1=15
In congruent triangles, the corresponding angles are also congruent.
So, ∠K≅∠Q
∠K=42 and ∠Q=3x
So, 42=3x and x=14
Answer:
velocity v(t) = -2cos(t)+t+2
position s(t) =
average of position from 2 to 5 = 17.666
Step-by-step explanation:
velocity is anti-derivative/integral of acceleration
= -2cos(t)+t+C
v(0) = 0
0 = -2cos(0)+0+C = -2 +C; C = 2
v(t) = -2cos(t)+t+2
position is anti-derivative of velocity
=
s(0) = 3
3 = -2sin(0) + 0 + 0+ C
3 = C
s(t) =
average value of a function of a domain [a, b] is given by the equation
average of position from t = 2 to t = 5
= 2cos(5)+125/6+25+15 - 2cos(2) - 8/6 -4 + 6
=52.999 (use a calculator)
52.999/3 = 17.666

Answer:
2
Step-by-step explanation:
The frequency is how many times the score shows up in the data set
21,<u> 27</u>, 20, 29, 23, 21, 21, <u>27</u>, 26, 25
27 shows up 2 times so the frequency is 2
