Steve is buying an $1160 T.V on the installment plan. He makes a down payments of 200 he has to make monthly payment of 55.25 fo 21/2 years what is his finance charge
Answer:
Finance charge = $200
Step-by-step explanation:
Cost of the T.V. = $1160
Steve did the down payment = $200
Monthly payment done by Steve = $22.5
Duration for the periodic payments = 2.5 years
Number of periodic payments to be done = 12 × 2.5
= 30
Amount paid in periodic payments = Number of periodic payments done × amount paid in each month
= 30 × $55.25
= $1657.5
Total payment done = Down payment + Amount paid in periodic payments
= $200 + $1657.5
= $1857.5
Therefore, finance charges = Total payments done - cost of T.V.
= 1857.5 - 1657.5
= $200

Answer:
Domain: [-5,4)
Range: (0, 4]
Step-by-step explanation:
You can see that the domain does not include the number four because of the open dot marking that spot, and the range does not include 0 because of this same reason.

I need to solve for the angle, but I just don't know how to do it! The equation is: Cos A=Sin3A
Can someone explain the formula so I can know how to do it, I will really appreciate it!
9514 1404 393
Answer:
A = 22.5°, 45°, 112.5°, 202.5°, 225°, 292.5°
Step-by-step explanation:
Use the angle reduction formula to reduce this to an expression involving only sine or cosine, then solve the resulting higher-degree polynomial.
sin(3x) = 3sin(x) -4sin³(x)
Using the identity for cosine, we have the radical equation ...
√(1 -sin²(A)) = 3sin(A) -4sin³(A)
Squaring both sides, we have ...
1 - sin²(A) = 9sin²(A) -24 sin⁴(A) +16sin⁶(A)
Letting z = sin²(A), this is the cubic equation ...
1 -z = 9z -24z² +16z³
16z³ -24z² +10z -1 = 0
Solving this by the usual methods, we find its factors to be ...
(2z -1)(8z² -8z +1) = 0
8(2z -1)((z -1/2)² -1/8) = 0 . . . . quadratic in vertex form
Then the roots are ...
z = (1 ±√(1/2))/2, z = 1/2
The angle solutions are ...
A = arcsin(±√z)
Of course, these need to be adjusted to fall in the domain of interest, and checked for extraneous solutions.
For z = 1/2-√(1/8), the angles are ...
A = ±22.5° ⇒ 22.5°, 157.5°, 202.5°, 337.5°
For z = 1/2, the angles are ...
A = ±45° ⇒ 45°, 135°, 225°, 315°
For z = 1/2+√(1/8), the angles are ...
A = ±67.5° ⇒ 67.5°, 112.5°, 247.5°, 292.5°
The angles that are in bold are the actual solutions; the others are extraneous.
_____
All of the above is "the hard way." A much simpler approach is to take advantage of the identity ...
cos(a) -sin(b) = (1/2)·sin(b/2 -a/2 -π/4)·sin(b/2 +a/2 -π/4)
Then you can use the zero product rule to find (for a=A, b=3A) ...
(3A/2 -A/2 -π/4) = nπ ⇒ A = nπ +π/4 ⇒ 45°, 225°
(3A/2 +A/2 -π/4) = nπ ⇒ A = (nπ +π/4) ⇒ 22.5°, 112.5°, 202.5°, 292.5°
_____
Rewriting the equation as a function equal to zero, the solutions are the x-intercepts of the graph. In the attached, the x-axis is set to degrees.
f(A) = cos(A) -sin(3A) = 0

Answer:
x=15
Step-by-step explanation:
Well, you have 2 numbers that sum up to 90 (the angle) so you can first minus the one you know, making your number from 90-30=60. Now all thats left is the 4x=60, which you can do 60/4=15 to get your answer that x=15.
Answer:
x = 15
Step-by-step explanation:
The sum of 30 and 4x = 90, that is
4x + 30 = 90 ← equation to solve
Subtract 30 from both sides
4x = 60 ( divide both sides by 4 )
x = 15

An artist used silver wire to make a square that has a perimeter of 40 inches. She then used copper wire to make the largest circle that could fit in the square, as shown below. How many MORE inches of silver wire did the artist use compared to copper wire?
Answer:
The artist used 8.6 inches more of silver wire
Step-by-step explanation:
Perimeter of the square
P = 4*a
P = 4*a = 40 in
a = 10 in
Each side of the square has a length of 10 in
The diameter of the circle is equal to the length of the side of the square
Diameter = 10 in
Perimeter of the circle
P_c = 2*π*radius = π*diameter
P_c = (3.14)*10 in = 31.4 in
Inches of silver wire (square) = 40 in
Inches of copper wire (circle) = 31.4 in
40- 31.4 in = 8.6 in

-- these are called same side exterior angles, which means they are supplementary.
x + 9 + 2x + 6 = 180
3x + 15 = 180
3x = 165
x = 55
so, option B.
x=3
Step-by-step explanation:
(x+9)°=(2x+6)°(by alternate exterior angle)
9-6=2x-x
3=x
check
(x+9)°=(2x+6)°
put value
3+9=2×3+6
