Todd is 2 years old.
2 times 4 = 8.
8 + 7 = 15.
15 - 11 = 4.
4 divided by 2 = 2.

Answer:
21 cookies
Step-by-step explanation:
First we know that Chris was given a third of 84 cookies so we can start working on this problem by figuring out what a third of 84 is. We can do this by multiplying 84 by 1/3 or just dividing by 3, which gives us: 84/3 = 28
So now we know that Chris was given 28 cookies, we can figure out what 3/4 of that is to work out how many cookies he ate. 28 x (3/4) = 21 cookies.
Chris ate 21 cookies.
Hope this helped!
Answer: Option A) x=3π/4, x=5π/4
The asymptotes of the function tan (z) are the values of z that are the odd multiples of <span>π/2:
</span>z=(2n+1)π/2, witn n= ..., -3, -2, -1, 0, 1, 2, 3, ...
In this case z=<span>2x − π, then:
</span>2x − π=(2n+1)π/2
Solving for x: Adding π both sides of the equation:
2x − π+ π=(2n+1)π/2+ π
Adding the terms on the right side of the equation:
2x=[(2n+1)π+2π]/2
Common factor π:
2x=[(2n+1)+2]π/2
2x=(2n+1+2)π/2
2x=(2n+3)π/2
Multiplying both sides of the equation by 1/2:
(1/2)(2x)=(1/2)[(2n+3)π/2]
(2/2)x=(2n+3)π/[(2)(2)]
x=(2n+3)π/4
For n=-1:
x=[2(-1)+3]π/4
x=(-2+3)π/4
x=π/4
x=π/4<π/2 No
For n=0:
x=[2(0)+3]π/4
x=(0+3)π/4
x=3π/4
π/2<x=3π/4<3π/2 Ok
For n=1:
x=[2(1)+3]π/4
x=(2+3)π/4
x=5π/4
π/2<x=5π/4<3π/2 Ok
For n=2:
x=[2(2)+3]π/4
x=(4+3)π/4
x=7π/4
x=7π/4>3π/2 No
Answer: x=3π/4, x=5π/4
