Answer:
y = 800•1/2^x
Step-by-step explanation:
Looking at the table, we can see that as we have an increase in x values, y values are halved
This probably means that the table represents an exponential function
The general form of this is;
y = a•b^x
From the first point
800 = a*b^0
800 = a * 1
a = 800
Using the second point;
400 = 800 * b^1
b = 400/800
b = 1/2
So we have the equation as;
y = 800•1/2(^x)

Answer:
1. 180
2. 52
3. 288
Step-by-step explanation:
The area of a rectangle can be found by multiplying the length by the width, so the area of the rectangle is 15 * 12 = 180. The area of a triangle can be found by multiplying the base by the height and divide by 2, so the area of the triangle is [tex]13*\frac{8}{2} = 13 * 4 = 52[/tex]. The area of a parallelogram can be found by multiplying the length and the height, so the area of the parallelogram is 24 * 12 = 288.
Two friends shop for fresh fruit. Jackson buys a watermelon for $7.85 and 5 pounds of
cherries. Tim buys a pineapple for $4.15 and 4 pounds of cherries. Use the variable p to represent
the price, in dollars, per pound of cherries. Write and simplify an expression to represent how much
more Jackson spent.
Answers
Answer:

A bag contains 9 marbles: 3 are green, 4 are red, and 2 are blue. Teresa chooses a marble at random, and without putting it
back, chooses another one at random. What is the probability that the first marble is blue and the second is green? Write
your answer as a fraction in simplest form.
Answers
Answer:
Probability[First marble blue, second is green without replacement] = 1/12
Step-by-step explanation:
Given:
Number of green marble = 3
Number of red marble = 4
Number of blue marble = 2
Total marble = 9 marble
Find:
Probability[First marble blue, second is green without replacement]
Computation:
Probability of an event = Number of favorable outcome / Number of total outcome
Probability[First marble blue] = 2 / 9
Probability[second is green] = 3 / [9-1]
Probability[second is green] = 3 / 8
Probability[First marble blue, second is green without replacement] = Probability[First marble blue] x Probability[second is green]
Probability[First marble blue, second is green without replacement] = [2/9][3/8]
Probability[First marble blue, second is green without replacement] = 6 / 72
Probability[First marble blue, second is green without replacement] = 1/12

Anyone know the answer to this?
Answers
Answer:
65
Step-by-step explanation:
This question can be solved using the Pythagorean Theorem, which is [tex]a^{2}+b^{2}=c^{2}[/tex] where a and b are legs and c is the hypotenuse. The equation used to solve for one leg is [tex]a=\sqrt{c^{2}-b^{2} }[/tex]. So, plug in the given measurements and solve. This turns into [tex]a=\sqrt{97^{2}-72^{2} }[/tex], which equals 65.
Answer:
a = 25
Step-by-step explanation:
First lets identify the formula
a^2 + b^2 = c^2
C would be the hypotenuse, across from the right angle. a is already labeled for us so be would be the bottom side.
Since we don't know the value of a we keep that as a variable
would would substitute b and c with the given values
a^2 + 72^2 = 97^2
Now, you could solve the squares but we are not going to. We are going to square root all the values to get rid of the squares so there is no point squaring it when your just going to end up with the same value just without the little square symbol at the top.
[tex]\sqrt{a^{2} } + \sqrt{72^{2} } = \sqrt{97^{2} }[/tex]
a + 72 = 97
Now its just the basic solving of get the variable on one side.
Subtract 72 from 97
a + 72 (-72) = 97 (-72)
a = 25
a is 25 feet

Studies have shown that 400 people attend a high school basketball game when the admission price is
$3.00. In the championship game, admission prices will increase. For every $0.25 increase, 20 fewer
people will attend. At what ticket price will the revenue be maximized?
Answers
Answer:
Let x=number of $0.25 increases, so the equation for revenue=price*number of tickets or people) becomes
Revenue=($3.00+$0.25x)(400-20x)
where ($3.00+$0.25x) :increase in price
and
(400-10x) : decrease in number of people
Expanding Revenue
Revenue[R]=1200-60x+100x-5x²:1200+40x-5x²
Taking the derivative of R and set it equal to 0:
R'=0+40-10x=40-10x
we have
R'=0
40-10x=0
x=40/10
x=4
So the ticket price is $3.00+$0.25*4=$4
The number of people will attend is 400-20*4=$320
At $320 ticket price will the revenue be maximized.
Step-by-step explanation:
A $320 ticket price will the revenue be maximized

Subash is saving to buy a video game that costs $72. He earns $12 per week for doing the dishes and spends $3 on ice-cream. Which equation can be used to find how many weeks it will take him to save enough money for the video game?
Answers
Answer:
Correct answer is 'A'
Step-by-step explanation:
so money he save per week = $12 - $3 = $9
Now,
To earn 9$ it takes one week or it can be represented as:
$9 = 1 week
So,
$1 = 1/9 week
$72 = (1/9*$72)weeks
$72 = 8 weeks
therefore it will take 8 weeks to save enough money for the video game
