We can use the vertex form of the quadratic function:
f(x) = a(x - h)^2 + k
where:
Vertex = (h, k)
“a” determines whether the graph opens up or down.
* If “a” is negative, the graph opens down.
The value of “a” also makes the parent function wider or narrower.
The value of “h” determines how far left or right the parent function is translated.
The value of “k” determines how far up or down the parent function is translated.
Given these information, we can plug in the value of the vertex into the vertex form:
f(x) = a(x - h)^2 + k
f(x) = a(x - 2)^2 + 7
Next, to solve for “a”, we can use one of the points on the graph, (1, 5), and plug these values into the equation:
f(x) = a(x - 2)^2 + 7
5 = a(1 - 2)^2 + 7
5 = a(-1)^2 + 7
5 = a(1) + 7
Subtract 7 from both sides:
5 - 7 = a(1) + 7 - 7
-2 = a
Therefore, a = -2. Now, we can establish the following quadratic function in vertex form:
f(x) = -2(x - 2)^2 + 7

The smaller of two consecutive integers is x - 1

2x = 3x - 18 Subtract 3x from both sides

Ben is a waiter at a restaurant. on Saturday, Ben got up at 6:30am, started work at X.am and finished work at X.pm. how long in hours did Ben work that Saturday
Answers
Answer:
12 hours
Step-by-step explanation:
X = 6:30
From 6:30 am to 6:30 pm = 12 hr
The number of hours that Ben worked at the restaurant can be calculated by the expression, Xpm - Xam.
The number of hours that Ben worked can be represented as:
= Time he finished working - Time he started working
= X pm - X am
If for instance, he started work at 7 am and finished at 12 pm, he would have worked:
= 12 - 7
= 5 hours
The expression that shows the length of time he worked can therefore be concluded to Xpm - Xam.

A man intended to distribute a certain amount of money he had, by giving 2/5 to his wife and the remaining amount equally to his three sons. However, he had to give 1/6 of this amount to his brother before he distributed it as intended. He distributed the remaining amount as originally intended.
Q1. The amount a son received was 40000 rupees less than the amount he was to receive originally. Find the amount the man had intially ?
Answers
9514 1404 393
Answer:
12,00,000 rupees
Step-by-step explanation:
The fraction originally intended for each son was ...
(1/3)(1 -2/5) = 1/3(3/5) = 1/5
The fraction each son actually received was ...
(1 -1/6)(1/5) = (5/6)(1/5) = 1/6
The difference in these amounts as a fraction of the original distribution is ...
1/5 - 1/6 = (6/30) -(5/30) = 1/30
Then the original distribution is 30 times this difference:
30×40000 rupees = 12,00,000 rupees

work out the percentage change when a price of £70 is decreased to £49
Answers
Answer:
30% decrease in price
Step-by-step explanation:
Since 70-49=21, we know that the price decreased by 30 pounds. The formula to find a percentage decrease is that you should then divide the original number(70) by 21(that equals 0.3!) 0.3 as a percentage would then be 30%, so the answer is there is a 30% decrease in price.

Which conic's equation has 2 squares with the same signs and different leading coefficients?
Answers
We want to see which is the conic equation that has 2 squares with the same sign and different leading coefficients.
We will see that it is the equation of the ellipse.
Now let's see why that is the correct answer.
The general conic equation is of the form:
[tex]A*(x - a)^2 + B*(x - b)^2 = R^2[/tex]
Where A and B are the leading coefficients, (a, b) is the center of the figure, and R is the average radius of the figure.
For example, if A = B, this would be the equation of a circle, but we must have two different leading coefficients.
If we write:
A = 1/C
B = 1/K
(both are positive, because "it has two squares with the same signs").
Then we get the equation:
[tex]\frac{ (x - a)^2}{C} + \frac{(x - b)^2}{K} = R^2[/tex]
We get the equation we wanted.
The same sign in both square parts and different leading coefficients.
The above equation is the general equation of an ellipse.
