The equation of the parabola that similar to f(x) = 7x^2 but the vertex is (3, 5) in the standard form is y = 7(x-3)^2 + 5

The equation of the parabola

f(x) = 7x^2

The standard vertex form of a parabola is

y = a(x-h)^2 + k

The coordinates of the vertex of a parabola = (3, 5)

Where (h, k)  is the coordinates

From the given function of the parabola f(x) =  7x^2

The value of a = 7

Substitute the values in the vertex form of a parabola

y = 7(x-3)^2 + 5

Hence, the equation of the parabola that is similar to f(x) = 7x^2 but the vertex is (3, 5) in the standard form is y = 7(x-3)^2 + 5

At the coffee shop, two coffees and one latte cost $10.50. Three coffees and two lattes cost $17.00. What is the cost of one cof
EastWind [94]

To solve this problem, we can set two equations.

Let x be the cost of coffee and y be the cost of latte.

Two coffees and one latte: 2x + y = 10.50

y=10.50 - 2x ...(1)

Three coffees and two lattes: 3x + 2y = 17.00...(2)

Put (1) into (2), we have:

3x + 2(10.50-2x) = 17.00

3x + 2(10.50) - 2(2x) = 17.00

3x + 21 - 4x = 17

Put the unknown to one side:

3x -4x = 17 - 21

-x = -4

When there are negative numbers on both sides, we can take the negative signs away:

x= 4

Therefore, cost of one coffee is A. $4.00.

Hope ot helps!

The quadrilaterals JKLM and PQRS are similar.
Sveta_85 [38]

Answer:

x = 2.8

Step-by-step explanation:

If the quadrilaterals are similar, then the ratios of corresponding sides will be equal:

KL : QR = 4 : 5.6 = 4 / 5.6 = 5/7

JM : PS = 7 : 9.8 = 7 / 9.8 = 5/7

LM : RS = 3 : 4.2 = 3 / 4.2 = 5/7

This shows that the ratio of KJ : QP = 5/7

KJ : QP = 2 : x = 2 / x

Therefore, \frac{2}{x}=\frac{5}{7}

cross multiply:  14 = 5x

Divide both sides by 5:  x = 2.8

Find the length of a line segment with endpoints of 19 and –39.. .
jenyasd209 [6]
This question we do not have to over think. We can already answer this with out the help of the diagram. The diagram helps us see that this problem involves the number line. Positive and negative numbers are involved in the number line. 

Here how we can think about it: From the middle to the left the length is 39 and to the right it is 19. The length is then 58.
