250 laps total. I used cross multiplication to solve it
Answer:
6233500
Step-by-step explanation:
We are given that CEO of a company that sells car stereos has determined the profit x number of stereos.
The profit of selling x number of stereos is given by
We have to find the value of profit when the company selling 12500 stereos.
Substitute the value of x=12500
Then, we get
Hence, the company should expect profit 6233500 from selling 12500 stereos.
(f - g)(x) = 4x +1 - ( x^2 - 5)
(f - g)(x) = 4x + 1 - x^2 + 5
(f - g)(x) = -x^2 + 4x + 6
Answer is C.
-x^2 + 4x + 6
21−=2(2−)=2cos(−1)+2 sin(−1)
−1+2=−1(2)=−1(cos2+sin2)=cos2+ sin2
Is the above the correct way to write 21− and −1+2 in the form +? I wasn't sure if I could change Euler's formula to =cos()+sin(), where is a constant.

No. It is not true that =cos()+sin(). Notice that
1=1≠cos()+sin(),
for example consider this at =0.
As a hint for figuring this out, notice that
+=ln(+)
then recall your rules for logarithms to get this to the form (+)ln().
Answer:
y=-3x+10
Step-by-step explanation:
Slope formula y2-y1/x2-x1
7-1/1-3
simplify
6/-2
simplify
-3
now plug -3 into y=mx+b
y=-3(x)+b
choose any point and plug it into the equation, I am using (3,1)
1=-3(3)+b
simplify
1=-9+b
add 9 to both sides
b=10
plug into slope-intercept form
y=-3x+10
