The value of a textbook is $63 and decreases at a rate of 14% per year for 13 years.
The exponential function that models the situation is y = 63(0.86).
After 13 years, the value of the textbook is $
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.

-At the end of 5 years, the balance was $5,200.
What is the interest rate on this account?
Answers
Answer:
6%
Step-by-step explanation:
Subtract 4000 from 5200 . This is the amount of interest earned after 5 years.
Divide that by 5. This is the amount earned after 1 year.

A Pizza factory has come out with two kinds of pizzas.A square pizza of side 26 cm costs AED 80 and a circular pizza of diameter 28cm costs AED 80. Which pizza is a better deal? Justify your answer.[=227].
Answers
Answer:
Square pizza
Step-by-step explanation:
To obtain which pizza is the best buy:
Cost of square pizza :
AED 80
side length, s = 26cm
Area of square, A = s²
A = 26² = 676 cm²
1 AED of square pizza gives : 676 / 80 = 8.45 cm²
Cost of circular pizza :
AED 80
Radius, r = 28cm
Area of circle, A = πr²
A = 22/7 * 14 * 14 = 22 * 2 * 14 = 616 cm²
1 AED of circular pizza gives : 616 / 80 = 7.7cm²
Hence, square pizza is the better buy ;
8.45cm² > 7.70 cm²

VW = √2
Step-by-step explanation:
y = x+1
x²+y²+2x+2y+1=0 (x²+2x+1) + (y²+2y+1) = 1
(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
y = 0 or y = -1
V and W: (-1 , 0) and (-2 , -1) forms a 90° center angle
√vw = √1²+1² = √2

write the equation of a line that has a slope of 3x - 4y = 12 and passes through the point (8, 8)
Answers
3x - 4y = 12
-4y = 12 - 3x
y = -3 + ³/₄ x
y = ³/₄x - 3
so the slope is ³/₄
now the equation is :
y-y₁ = m (x-x₁)
y-8 = ³/₄ (x-8)
y-8 = ³/₄ x - 6
y = ³/₄ x -6 + 8
y = ³/₄x + 2
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=120
Equilibrium quantity is 120 mowers

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
