Given that the discriminant of a quadratic equation is 8, determine the number of real solutions.

Answers

Answer 1

Answer:

There are two real solutions.

Step-by-step explanation:

There are only three possible solutions for the discriminant of a quadratic equation:

1. D < 0

In this case there are no real solutions. The graph does NOT intersect with the x-axis.

2. D = 0

In this case there is exactly one real solution. The graph touches the x-axis in one point, which is called the Top.

3. D > 0

In this case there are two real solutions. The graph intersects the x-axis in two points.

alice is building a fenced in pen in her backyard for her dog,as shown. write an expression that represents the total amount of fencing she will need in feet. if the longer dimensions of the rectangle is 27 feet how many feet of fencing does Alice need?

Answers

Answer:

p = 2 * w + 54

Step-by-step explanation:

To know the number of feet Alice needs, you must calculate the perimeter, the perimeter of a rectangle would be the sum of its sides, that is, twice the width and twice the length.

This time they give us the length that is equal to 27 feet, therefore, the equation of the perimeter would be:

p = 2 * w + 2 * l

p = 2 * w + 2 * 27

p = 2 * w + 54

Therefore, to know exactly what Alice needs, you need to know the value of the width and shortest side.

Answers

Answer:

A) 5x-7y=42

Step-by-step explanation:

We know that 5 x 7 = 35 then add 7 = 42

We divide 5 and 7 by 5/7

5/  5/7 = 0.1

7/ 5/7 = 0.2

We find 0.1 = 1/10 and we know that 1/10 of 35 is 3.5

We find 0.2 = 2/10 and we know that 2/10 of 35 is 7 so the answer 7 matches.

We then use 7 for y and keep 5 for x.

What is the angles mSRW?

Answers

Answer:

126°

Step-by-step explanation:

(2x +18)° = (3x)°

2x + 18 = 3x

18 = 3x - 2x

18 = x

therefore, (3x)° = (3*18)°= (54)°

[tex]m\angle SRW + (3x)\degree = 180\degree \\

m\angle SRW + 54\degree  = 180\degree \\

m\angle SRW = 180\degree  - 54\degree  \\

Step-by-step explanation:

so 4 would be negative because it decreased and 2 would be positive because it increased so multiply -4 by 3 wich is -12 then add it by 2 times 4 which is 8 and it is -4

The addition is one of the four fundamental mathematical operations. The correct option is B.

What is Addition?

The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

Given that the price of a stock decreased $4 per day for 3 days and increased $2 per day for 4 days. Therefore, The change in the price of the stock is,

Change in the price = (-$4 × 3 days) + (+$2 × 4 days)

                                  = -$12 + $8

                                  = -$4

Hence, the correct option is B.

How many ways can you order your favorite 3 desserts from a menu of 8?

6720

6

40,320

336

Answers

Answer:

336

Step-by-step explanation:

The total number of ways to order your favorite 3 desserts from a menu of 8 is 336, the correct option is D.

How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?

We can use combinations for this case,

Total number of distinguishable things is m.

Out of those m things, k things are to be chosen such that their order doesn't matter.

This can be done in total of

[tex]D ^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]

If the order matters, then each of those choice of k distinct items would be permuted k! times.

So, total number of choices in that case would be:

[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]

This is called permutation of k items chosen out of m items (all distinct).

We are given that;

The number of ways to order 3 desserts from a menu of 8 is given by the combination formula:

C(8,3) = 8! / (3! * (8-3)!) = 56

This means there are 56 different ways to choose 3 desserts from the menu of 8. Once the desserts are chosen, there are 3! = 6 ways to order them.

For 3 desserts from a menu of 8

56 * 6 = 336

Therefore, by  combinations and permutations answer will be 336.

Answer:

Option 1

Step-by-step explanation:

Counter-intuitively, the correct answer is option 1. Option 2 is obviously a cross section, since it is the shape of the base of the triangle. Option 3 is also obviously a cross section, since the figure is a triangular prism. Option 4 is a cross section because, if you slice diagonally, you may create a cross section with a wider base on the bottom and larger on top. However, it is impossible to create a cross section of a rectangle from this square pyramid. Hope this helps!

Answers

Answer: C. 35

Step-by-step explanation:

x + 73 + 51 + 21 = 180

180-73-51- 21 = x

x = 35

Answer:

X= 35

Step-by-step explanation:

In order to find X, you need to add all the known angles together

- 73+ 51+ 21+ 145

Because the total degrees of an angle is 180 degrees, you need to subtract the known degrees from the total

- 180- 145= 35  

x = 35

Answer:

x = 20

y = 10

Step-by-step explanation:

Since we have a right triangle then:

sin(60) = 10√3/x ⇒ x = 10√(3)÷sin(60) = 20

cos(60) = y/20 ⇒ y = 20×cos(60) = 10

Answer:

Option B)

The value of x is 20 and y is 10

Step-by-step explanation:

Here, in a given right triangle

ΔABC, m∠B = 90°

Now,

tanθ = opposite ÷ adjacent

tan 60° = 10√3 ÷ y

√3 = 10√3 ÷ y

y = 10√3 ÷ √3

y = 10

Now,

sinθ = opposite ÷ hypotenuse

sin 60° = 10√3 ÷ x

√3 ÷ 2 = 10√3 ÷ x

√3 × x = 10√3 × 2

x = 20√3 ÷ √3

x = 20

Thus, The value of x is 20 and y is 10
