Henry went to an amusement park with $100.00 and spent all of it. He spent of the money on parking. He spent $42.50 on admission to the park. He spent 20% of the money on food. He paid a $12.75 fee for admission into a water park located inside the amusement park. He spent the remainder of his money on games that cost $1.75 each. How many games did Henry play?
Answers
Answer:
19 games
Step-by-step explanation:
Henry went to an amusement park with $100.00 and spent all of it.
Starting amount = $100.00
He spent $42.50 on admission to the park.
Amount left = $100.00 - $42.50
Amount left = $57.5
He spent 20% of the money on food.
Amount spent = 20% of amount left ($57.5) = $11.5
Amount left = $57.5 - $11.5 = $46
He paid a $12.75 fee for admission into a water park located inside the amusement park.
Amount left = $46 - $12.75
Amount left = $33.25
He spent the remainder of his money on games that cost $1.75 each. How many games did Henry play?
Number of games = Amount left / Cost per game
Number of games = $33.25 / $1.75 = 19
Given the two functions, which statement is true?
(function is in picture)
A) g(x) is stretched vertically by a factor of 2 and shifted to the right 4 units compared to f(x).
B) g(x) is shrunk vertically by a factor of ½ and shifted to the right 4 units compared to f(x).
C) g(x) is stretched vertically by a factor of 2 and shifted to the left 4 units compared to f(x).
D) g(x) is shrunk vertically by a factor of ½ and shifted to the left 4 units compared to f(x).
Answers
Answer:
Option D
Step-by-step explanation:
f(x) = [tex]\text{log}_{15}x[/tex]
Transformed form of the function 'f' is 'g'.
g(x) = [tex]\frac{1}{2}\text{log}_{15}(x+4)[/tex]
Property of vertical stretch or compression of a function,
k(x) = x
Transformed function → m(x) = kx
Here, k = scale factor
1). If k > 1, function is vertically stretched.
2). If 0 < k < 1, function is vertically compressed.
From the given functions, k = [tex]\frac{1}{2}[/tex]
Since, k is between 0 and [tex]\frac{1}{2}[/tex], function f(x) is vertically compressed by a scale factor [tex]\frac{1}{2}[/tex].
g(x) = f(x + 4) represents a shift of function 'f' by 4 units left.
g(x) = f(x - 4) represents a shift of function 'f' by 4 units right.
g(x) = [tex]\frac{1}{2}\text{log}_{15}(x+4)[/tex]
Therefore, function f(x) has been shifted by 4 units left to form image function g(x).
Option D is the answer.

A small plant manufactures riding lawn mowers. The plant has fixed costs of GHC48,000 per day and a variable cost of GHC1,400 per unit produced. The mowers are sold for GHC1,800 each. The cost and revenue functions are in that order and , where is the total number of mowers produced and sold each day. How many units must be manufactured and sold each day for the company to break even?
Answers
Answer:
120
Step-by-step explanation:
The break-even point is the point where revenue =cost
48,000+ 1400x = 1800x
48000=400x
X=48000/400

(x+1)² + (y+1)² = 1 : Circle: (x-h)² + (y-k)² = r² Center (O): (h , k) = (-1 , -1) r = 1
solve for roots: x²+(x+1)²+2x+2(x+1)+1=0
2x² + 6x + 4 = 0 x²+3x+2=0
(x+1)(x+2)=0
x = -1 or x = -2

Answers
Answer:
An exponential function is given by;
f(x)=ba^x
where a is any value greater than 0,
b is the intial value
when a>1 then f(x) is defined as an exponential growth
when a<1 then f(x) is defined as an exponential decay
From the our function;
f(t)=15000(0.86)^t
a=0.86<1
b=15000
since a<1, the function will be an exponential decay.
