Answer:

The vertex of the quadratic equation is the point (4,2)

Step-by-step explanation:

we know that

The figure show a vertical parabola open downward

The vertex represent the maximum point of the graph

Looking at the graph

The maximum point of the graph is (4,2)

therefore

The vertex of the quadratic equation is the point (4,2)

Answer:

The answers to each part are:

Part A.

The quantity of apples is one-third of the quantity of grapes.

Part B.

The quantity of apples is a quarter of the quantity of strawberries.

Part C.

The number of cherries is two-elevenths of the total fruit.

Step-by-step explanation:

To identify the answer in each case, you must remember that all the parts are equal, then:

Part A.

The parts of apples are 1 and the parts grapes are 3, so if you divide the first quantity with the second quantity you obtain:

1 / 3 = 1/3 (one-third)

So, the quantity of apples is one-third of the quantity of grapes or the quantity of apples is three times smaller than the quantity of grapes.

Part B.

The parts of apples are 1 and the parts of strawberries are 4, then you must divide the first quantity with the second quantity:

1 / 4 = 1/4 (a quarter)

In this case, the quantity of apples is a quarter of the quantity of strawberries or the quantity of apples is four times smaller than the quantity of strawberries.

Part C.

First, you must add all the part of fruit:

1 part apple
1 part orange
4 parts strawberry
2 parts cherry
3 parts grape

The total of fruits is 11 parts, taking into account the quantity of cherries is 2, now you can divide the number of cherries with the total parts of fruit:

2 / 11 = 2/11 (two-elevenths)

Now, you can see the number of cherries is two-elevenths of the total fruit.

What is the volume of this entire prism

lisabon 2012 [21]

Answer:

520 cubic centimeters (cm^3)

Step-by-step explanation:

volume = length * width * height

length = 13

width = 5

height = 4 + 4, so height = 8

volume = (13) * (5) * (8)

volume = 520 units

Since the given measurements are in centimeters and the answer is the volume of the prism, the answer must be in cubic centimeters

So, the final answer is 520 cubic centimeters (cm^3)

How do you check 3(2x-5)-4=33 ?

amid [387]

First multiply 2x - 5 by 3 amd will open the brackets

3(2x-5)-4=33

6x - 15 - 4 = 33

6x - 19 = 33

Take -19 to other side and its sign will be become +

6x = 33 + 19

6x = 52

$x \: \: = \frac{52}{6}$

x = 8.6

WILL MARK AS BRAINLIEST 4. Suppose there is a card game where you are dealt a hand of three cards. You have already learned that

Alexeev081 [22]

Answer:

Part A- 6

Part B- 3

Part C- 3/22100

Step-by-step explanation:

Part A-

Use the permutation formula and plug in 3 for n and 2 for k.

nPr=n!/(n-k)!

3P2=3!/(3-2)!

Simplify.

3P2=3!/1!

3P2=6

Part B-

Use the combination formula and plug in 3 for n and 2 for k.

nCk=n!/k!(n-k)!

3C2=3!/2!(3-2)!

Simplify.

3C2=3!/2!(1!)

3C2=3

Part C-

It is given that the total number of three-card hands that can be dealt from a deck of 52 cards is 22100. Use the fact that the probability of something equals the total successful outcomes over the sample space. In this case the total successful outcomes is 3 and the sample space is 22100.

I believe the answer is 3/22100

I honestly suck at probability but I tried my best.
