Answer:
This skill will come in handy when working with word problems or real life situations.
Answer:
I believe the answer is D
Step-by-step explanation:
I did it by eliminating all other options
A cant be true because with a 90 degree rotation RS is going to be perpendicular to R'S', not parallel.
B can't be true because SP is a straight line and R'S' like RS wont be (rotation doesn't change the fact that it isn't a completely straight line.
Now, rotation doesn't affect the degree of an angle. so...
C can't be true because 60 degrees isnt just going to change to 80 degrees out of nowhere
but D can be true because of this rule.
I hope this helps!
Answer:
Statement 4 in true.
Step-by-step explanation:
1. f(-2)=(-3*(-2)+2)^2+(-2)=(6+2)^2+(-2)=8^2-2=62, FALSE
2. f(-5)=(-3*(-5)+2)^2+(-5)=(15+2)^2+(-5)=17^2+(-5)=289-5=284, FALSE
3. f(3)=(-3*3+2)^2+3=(-9+2)^2+3=(-7)^2+3=49+3=52, FALSE
4. f(5)=(-3*5+2)^2+5=(-15+2)^2+5=(-13)^2+5=169+5=174, TRUE
Answer:
16
Step-by-step explanation:
2 times 2 is 4, 4 times 2 is 8, 8 times 2 is 16
Expected number of wins=number of plays times the probability of winning
w=20(14.5/100)
w=20(0.145)
w=2.9
w≈3
So you would expect to win 3 times out of 20 attempts (rounded to the nearest whole number of wins)
