What is the equation of the graph below?
2 answers:
<h2>Answer:</h2>
The equation of the given graph is:
We know that the general equation of a downward parabola with vertex at (h,k) is given by the formula:
where a<0
Here in each of the options we have a= 1 or -1
but as a has to be less than 1 this means that a= -1
Also, we have: (h,k)= (3,1)
i.e. h=3 and k=1
Hence, putting the values of h,k and a in the general equation we get:
Hence, the equation of parabola is:

The cost of TV is $ 792 and cost of DVD player is $ 264
<u>Solution:</u>
Given, total cost of television and dvd player = 1056
The cost of the television is three times the cost of the dvd player.
Now, let the cost of DVD player be "n", then the cost TV will be (1056 – n)
And, we know that, cost of TV is 3 times Cost of DVD
So, the cost of DVD player is $264, the cost of TV will be (1056 - 264) = $792
Answer:
Option C 41%
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The number of people who own at most three t-shirts costing more than $19 each is equal to the number of people who own one t-shirt costing more than $19 each, plus the number of people who own two t-shirt costing more than $19 each, plus the number of people who own three t-shirt costing more than $19 each
Observing the graph
The number of people who own one t-shirt costing more than $19 each is 5
The number of people who own two t-shirt costing more than $19 each is 17
The number of people who own tree t-shirt costing more than $19 each is 23
The number of people who own at most three t-shirts costing more than $19 each is
To find out the percentage divided the number of people who own at most three t-shirts costing more than $19 by one hundred eleven people (total people that shopped in a store) and then multiply by 100

Remember that a conditional statement (p→q) is an if-then in which the first part, p, is the hypothesis and the second part, q, is the conclusion.
1. Here the set m<span>∠A=40° is a subset of the set Acute Angles, so </span>m∠A=40° is the hypothesis and Acute Angles is the conclusion.
In other words:
m∠A=40°→∠A is an Acute Angle
if m∠A=40°, then ∠A is an Acute Angle
We can conclude that the conditional statement that describes the Venn diagram is: if m∠A=40°, then ∠A is an Acute Angle
2. Just like before, the set
is a subset of the set 
; therefore, is the hypothesis and is the conclusion.
In other words:

if, then
We can conclude that the conditional statement that describes the Venn diagram is: if, then
