Answer:
23 Seconds
The roach is going 2 feet per second so you can split the amount of feet in half because he will go the same distance 2 times as fast.
Answer:
m-45=-78
25=x+9
x and y are proportional, because they are doubling the outcome every time by 3, so the slope would simplify to 1/4 very time.
Step-by-step explanation:
Answer:
The answer is 144,5
Step-by-step explanation:
144,5/170×100 =85%
very simple, we use the formula sin(a+b)=sinacosb +
sinbcosa and sin(20)=2sinacosa
5pi = 2pi/3+3pi/3,
First, we use sin(a+b)=sinacosb + sinbcosa
sin(5pi/3)=sin(2pi/3+3pi/3)=
sin(2pi/3+pi)=
sin(2pi/3)cos(pi) +sin(pi)cos(2pi/3)
but we know that sin(pi)=
0, and cos (pi) = -1, so sin(5pi/3)=
- sin(2pi/3)
now, use sin(2a)=2sinacosa,
sin(5pi/3)= - sin(2pi/3)= -2sin(pi/3)cos(pi/3)
sin<span>(5pi/3)=
-2sin(pi/3)cos(pi/3)</span>
<span>sin(pi/3)= 0.86,
cos(pi/3)=0.5, finally we have </span>sin<span>(5pi/3)= -0.86 x 0.5= -0.43</span>
Equations are given,
y= x+2
<span>
y= -4x+7
As you can see both the expressions, x+2 and -4x+7 are equal to "y". That means they are equal to each other too.
So let's equal them and solve it.

Now we have x's value we will plug it in the first equation to find "y".
