Tim has a collection of model cars and boats.he has 3 cars for every 2 boat. He has a total of 12 boats.
Answer:
18 cars
Step-by-step explanation:
6 times 2= 12 boats
3 times 6= 18 cars
Hopefully this helps!
Answer:

Samantha invested $50,000 in an account paying an interest rate of 4.1% compounded daily. Assuming no deposits or withdrawals are made, how much money, to the nearest ten dollars, would be in the account after 8 years?
Answer:
$69,408.17 = $69,410 rounded
Step-by-step explanation:
Final investment value
$69,408.17
Total interest earned
$19,408.17
Initial balance
$50,000.00
Total monthly deposits
$0.00
Effective Annual Rate (APY)
4.185%
The formula used in the compound interest calculator is A = P(1+r/n)^(nt)
A = the future value of the investment
P = the principal investment amount
r = the interest rate (decimal)
n = the number of times that interest is compounded per period
t = the number of periods the money is invested for

Regression Project: Find the Profit Model
Annual Widget Production x (widgets) Annual Total Cost c($)
10 609
20 1105
30 1523
40 2150
50 2603
60 3121
70 3672
80 4103
90 4601
100 5214
Recall that profit can be computed in terms of revenue and cost. Assume that the annual widget sales match the annual widget demand and annual widget production. Construct a model for profit using the models for revenue and cost that you found in the Revenue and Cost sections. Find the model for profit P ( x ), where P ( x ) is the total annual profit in dollars for x widgets sold, and write it as P ( x ) = a x 2 + b x + c. Note: You are using the fact that P ( x ) = R ( x ) − C ( x ), not creating a table of data.
value of a. -0.956
value of b. 106.2
value of c. ???????????????????? It is not 0, 73.4, 124.2, 104.87, 157, 50.8 I've tried all of these
Answer:
value of c is -73.4
Step-by-step explanation:
When you subtract revenue from cost the Profit model becomes
P(x)= -0.956x^2 + 106.2x - 73.4

Answer:
x= 9.37
y = 17.69
Step-by-step explanation:
in order to find the answer, use the trigonometries.
First finding x which is tan(32) = x/15
x = tan(32)15
and Y is cos(32) = 15/y
y = 15/cos(32)

Answer:
Step-by-step explanation:
Jose is right because the two angles are coresponding angles that are congruent
Question: Using only reciprocal, Pythagorean, sum/difference, and/or half angle identities, prove the equation below. You must use angles A and B, do not replace with actual vales. Only work with the right side of the equation. You should use TEN steps to accomplish this proof! cosA+cosB= 2cos(A+B/2)cos(A-B/2)
Answer:
See explanation below
Step-by-step explanation:
Recall the identity for the cosine of an addition of angles:
[tex]cos(\theta+\gamma)= cos(\theta)*cos(\gamma)- sin(\theta)*sin(\gamma)[/tex]
and that for a subtraction of angles:
[tex]cos(\theta-\gamma)= cos(\theta)*cos(\gamma)+sin(\theta)*sin(\gamma)[/tex]
Now, use the property of addition of angles above to write :
[tex]cos(\frac{A+B}{2} +\frac{A-B}{2} )=cos(\frac{A+B}{2} )*cos(\frac{A-B}{2} )-sin(\frac{A+B}{2} )*sin(\frac{A-B}{2} )[/tex]
but since : [tex]\frac{A+B}{2} +\frac{A-B}{2}= A[/tex]
Then the cosine of addition of angles above can be written as:
[tex]cos(\frac{A+B}{2} +\frac{A-B}{2} )=cos(\frac{A+B}{2} )*cos(\frac{A-B}{2} )-sin(\frac{A+B}{2} )*sin(\frac{A-B}{2} )\\cos(A)=cos(\frac{A+B}{2} )*cos(\frac{A-B}{2} )-sin(\frac{A+B}{2} )*sin(\frac{A-B}{2} )[/tex]
We do something similar now with the cosine of the subtraction of angles:
[tex]cos(\frac{A+B}{2} -\frac{A-B}{2} )=cos(\frac{A+B}{2} )*cos(\frac{A-B}{2} )+sin(\frac{A+B}{2} )*sin(\frac{A-B}{2} )[/tex]
and we notice that: [tex]\frac{A+B}{2} -\frac{A-B}{2}= B[/tex]
Then the cosine of subtraction of angles above can be written as:
[tex]cos(\frac{A+B}{2} -\frac{A-B}{2} )=cos(\frac{A+B}{2} )*cos(\frac{A-B}{2} )+sin(\frac{A+B}{2} )*sin(\frac{A-B}{2} )\\cos(B )=cos(\frac{A+B}{2} )*cos(\frac{A-B}{2} )+sin(\frac{A+B}{2} )*sin(\frac{A-B}{2} )[/tex]
and finally, we add term by term the expressions we got for cos (A) and for cos(B) and notice that the terms that contain the sine functions cancel each other because they have opposite signs, while the terms in cosine add up to double themselves:
[tex]cos(A )=cos(\frac{A+B}{2} )*cos(\frac{A-B}{2} )+sin(\frac{A+B}{2} )*sin(\frac{A-B}{2} )\\+\\cos(B )=cos(\frac{A+B}{2} )*cos(\frac{A-B}{2} )-sin(\frac{A+B}{2} )*sin(\frac{A-B}{2} )\\=\\cos(A) +cos(B)=2\,cos(\frac{A+B}{2} )*cos(\frac{A-B}{2} )[/tex]
which is what we wanted to prove.

Write in slope intercept form an equation of the line that passes through the given points. (0,4) (4,8) and (-2,3) (-4,4)
Answer:
y = 1.25x+4
Step-by-step explanation:
m = (y2-y1)/(x2-x1)
Substitute Values for one set of coordinates. I used (0,4) and (4,8)
Once you have derived what m is equal too, put it into your slope intercept form: y=mx+b
y=1.25x+b
b would be equal to 4 in this case (sorry i don't have enough time to explain why, but it is 4)
The final answer is y = 1.25x+4
