Suppose in 2008 the average cost of a movie ticket in the United States was $7. If
inflation causes ticket prices to increase by 4.5% a year, in what year will a ticket cost
$25?
a. 2025
b. 2037
c. 2029
d. 2040
Answer:
B) 2037
Step-by-step explanation:
using the problem an exponential equation can be made
7(1.045)× =25
--solve for x--
x=28.9
it will take 28.9 year for the price to get to $25 so add 2008 to 28.9 to get 2036.9
2037 is closest to 2036.9 so the answer is B

10) Calculate angle u, v and w
A
Y
с
88
68
Answer:
u = 24, v = 92, and w = 184
Step-by-step explanation:
According to circle theorem, we have;
∠ACD = ∠ABD = 88° by angle inscribed in a circle and also subtending the same chord
∠DOA = 2 × ∠ABD by angle subtended at the center = 2 × Angle subtended at the circumference
∴ ∠DOA = 2 × ∠ABD = 2 × 88° = 176°
w° + ∠DOA = 360 by the sum of angles at a point
∴ w° = 360° - ∠DOA = 360° - 176° = 184°
w° = 184°
w° = 2 × v° by angle subtended at the center = 2 × Angle subtended at the circumference
∴ v° = w°/2 = 184°/2 = 92°
v° = 92°
In triangle ΔCDY and ΔABY, we have;
∠ABD = ∠ABY by reflexive property
∠ACD = ∠ACY by reflexive property
∠ACD = ∠ABD = 88°
∴ ∠ABY = 88°
∠CYD = ∠AYB by vertically opposite angles are equal
∴ ∠CYD = 68° = ∠AYB
u° + ∠ABY + ∠AYB = 180° by angle sum property
∴ u° = 180° - (∠ABY + ∠AYB)
u° = 180° - (88° + 68°) = 24°
u° = 24°.
f(x) = x - 1. Find the inverse of f(x).
Answer:
f^-1(x) = x+1
Step-by-step explanation:
turn into y = x-1
1. Flip x to y and y to x
x = y-1
2. isolate y
x+1 = y
using a graph you can find it by reflecting x-1 over y=x
find two numbers if their sum is 3/5 and their difference is 7 1/5
Answer:
A = 3 + 9/10
B = -(3 + 3/10)
Step-by-step explanation:
We have two numbers, A and B, such that:
A + B = 3/5
A - B = 7 + 1/5
To solve this, we first need to isolate one of the variables in one of the equations, I will isolate A in the first equation:
A = 3/5 - B
Now we can replace this in the other equation:
A - B = 7 + 1/5
(3/5 - B) - B = 7 + 1/5
3/5 - 2*B = 7 + 1/5
-2*B = 7 + 1/5 - 3/5
-2*B = 7 - 2/5 = 35/5 - 2/5 = 33/5
B = -(33/5)/2 = -33/10 = - 30/10 - 3/10 = -3 - 3/10 = -(3 + 3/10)
Now that we know the value of B, we can use the equation
A = 3/5 - B
To find the value of A:
A = 3/5 - ( -(3 + 3/10))
A = 3/5 + (3 + 3/10) = 6/10 + 3 + 3/10 = 3 + 9/10
The numbers are:
A = 3 + 9/10
B = -(3 + 3/10)

Consider the following equation.
[tex]5^{-x}[/tex]+7=2x+4
Approximate the solution to the equation above using three iterations of successive approximation. Use the graph below as a starting point.
a. x=[tex]\frac{7}{4}[/tex]
b. x=[tex]\frac{27}{16}[/tex]
c. x=[tex]\frac{13}{8}[/tex]
d. x=[tex]\frac{25}{16}[/tex]
Answer:
C
Step-by-step explanation:
I think
The solution to the equation above using three iterations of successive approximation is x = 25/16
What is an equation?An equation is an expression that is represented by the equality or equal to sign i.e "="
The equation is given as:
[tex]5^{-x} + 7 =2x + 4[/tex]
Equate to 0
[tex]5^{-x} + 7 -2x - 4 = 0[/tex]
Express as a function
[tex]f(x) = 5^{-x} + 7 -2x - 4[/tex]
The equation has a solution when f(x) = 0.
From the graph, we have:
x = 1.5
So, we have:
[tex]f(1.5) = 5^{-1.5} + 7 -2*1.5 - 4[/tex]
Evaluate
f(1.5) = 0.089
Set x to 1.52 to determine a closer value of f(x) to 0.
[tex]f(1.52) = 5^{-1.52} + 7 -2*1.52 - 4[/tex]
Evaluate
f(1.52) = 0.047
Set x to 1.54 to determine a closer value of f(x) to 0.
[tex]f(1.54) = 5^{-1.54} + 7 -2*1.54 - 4[/tex]
Evaluate
f(1.54) = 0.004
Notice that 0.004 is closer to 0 than 0.047 and 0.089
From the list of options, the closest value to 1.54 is 25/16
Hence, the solution to the equation above using three iterations of successive approximation is x = 25/16

You have a square piece of bread that is 5 inches long and 5 inches wide. It it h inches high. The crust of the bread if 50% of the total surface area of the bread. What is the height, h, of the bread?
Answer:
2.5 inches
Step-by-step explanation:
equation :
(4×5) × h = 50% × [(2×5×5)+(4×5)×h]
20×h = 0.5 × (50 +20h)
20h = 25+10h
20h-10h= 25
10h = 25
h = 25/10
= 2.5 inches
