Find the missing side length using pythagorean theorem. simplify radicals if necessary* PLEASE HELP!!

Answer:

The quadratic equation has two complex solutions.

Step-by-step explanation:

5x² + 6x + 2 = 0

To know the the correct answer to the question, we shall determine the discriminant of the equation. This can be obtained as follow:

5x² + 6x + 2 = 0

ax² + bx + c = 0

Comparing the above equation, we can obtain:

a = 5

b = 6

c = 2

Discriminant (D) =?

D = b² – 4ac

D = 6² – (4 × 5 × 2)

D = 36 – 40

D = – 4

Since the discriminant of the equation is less than 0, it means that the equation has no real root ( i.e the equation has two complex solution).

Answer:

x = 10

Step-by-step explanation:

Subtract 5 from both sides:

2x + 5 = 25

2x = 20

Divide each side by 2

x = 10

Answer:

x=10

Step-by-step explanation:

25-5 = 20, so then you divide 20 by 2 to get 10

Answer:

Hello

Step-by-step explanation:

From the answer to the second Question...

x²-6x+9 = -13 + 9

Factorize L.H.S

x² - 3x - 3x + 9 = -4

x(x - 3) - 3(x - 3) = -4

(x - 3)(x - 3) = -4

(x - 3)² = -4

Hence the answer is

[tex] \color{purple}{ \boxed{ {(x - 3)}^{2} = - 4}}[/tex]

Answer:

-3 and -4 are the correct answers!!

Answer:

4/5 OR -4/5

Step-by-step explanation:

So, area of triangle = 1/2 * base * height

base = 5 (because x-axis is base, x-intercept is -5, so x-length = 5)

height is unknown

area = 10

We can form the equation: 1/2 * 5 * height = 10

Rearrange terms to get: height (y-height) = 10 / (0.5 * 5) = 4

Following the formula for gradient, dif in y / dif in x, we get 4/5

Therefore our gradient is (4/5), or 0.8.

But because we are only told the x-intercept, it can cross the y axis at y = 4 or y = -4. So there are actually 2 possible gradients, 4/5 and -4/5

Answer:

11.52%

Step-by-step explanation:

Price (p0) = 58.6

Dividend (D1) = 6.75

P0= D1/ke

58.6 = 6.75/ke

ke = 6.75/58.6

ke = 0.1152 or 11.52%

Rate of return (ke) = 11.52%

Answer:

2 2/3 cups of flour

Step-by-step explanation:

To answer this question you need to multiply 1 1/4 by 2 2/3

To multiply first make each mixed number an improper fraction

This means multiplying the whole number by the denominator, then adding the numerator

For example 1 1/4 would become 5/4 because 4 x 1 = 4 and 4 + 1 = 5, & 2 2/3 would be 8/3

Now multiply the numerator and denominator (5/4 x 8/3)

30/12 simplified to 8/3 (2 2/3)

Answer:

Cedric's share=$120

Abel's share=$60

Step-by-step explanation:

Abel will receive half as much as Cedric

Let

Cedric's share=x

Abel's share = 1/2 of x

Total money=$180

x + 1/2x = 180

2x+x/2 =180

3/2x=180

Divide both sides by 3/2

x= 180÷3/2

=180 × 2/3

=360/3

=120

Therefore,

Cedric's share = x = 120

Abel's share=1/2x

=1/2 × 120

=120/2

=60

Cedric's share=$120

Abel's share=$60

The probability is  [tex]P(X < 25) = 0.308[/tex]

Step-by-step explanation:

From the question we are told that

   The amount of time is uniform probability distribution between 21 and 38 minutes.

  Given that the amount of time is uniformly distributed then  the probability that a randomly selected car will require less than 25 minutes to service is mathematically evaluated as

           [tex]P(X < 25) = \frac{ 25 - 21}{38 - 21}[/tex]

=>       [tex]P(X < 25) = 0.308[/tex]

Step-by-step explanation:

-10r - 20 = -20

-10r = -20 + 20

-10r = 0

Answer:

A rectangle is a two - dimensional shape, so let me explain using it as an example.

The diagonal of a rectangle divides the rectangle into two triangles that are congruent (the same size and shape.)

Another example is parallelogram; the diagonal of a parallelogram also divides the figure into two separate shapes that are congruent.

Answer:

The width is 4 inches

The length is 11 inches

Step-by-step explanation:

Let the width  be x inches

Let the length be (2x+3 )inches

Perimeter= 30 inches

therefore, 2(length +breadth)= perimeter

        =>2(2x+3+x)=30

        =>2(3x+3)=30

         =>6x+6=30

          =>6x=30-6

          =>6x=24

           =>x=24/6

           =>x=4

The width is 4 inches

The length is 11 inches  

To solve this question:

Doing this, we get that the length of the painting is: 11 inches.

Perimeter of a rectangle:

The perimeter of a polygon is the sum of it's sides.

For a rectangle, as the one given in the picture at the end of this answer, which is of the format of the painting, the perimeter is given by:

[tex]P = 2l + 2w[/tex]

Lisa is framing a rectangular painting the length is three more than twice the width.

This means that:

[tex]l = 3 + 2w[/tex]

Since we want to solve for the length, we write the width as a function of the length, thus:

[tex]2w = l - 3[/tex]

She uses 30 inches of framing material

This means that the perimeter is of 30 inches, that is:

[tex]2l + 2w = 30[/tex]

Since [tex]2w = l - 3[/tex]

[tex]2l + l - 3 = 30[/tex]

[tex]3l = 33[/tex]

[tex]l = \frac{33}{3}[/tex]

[tex]l = 11[/tex]

Thus, the length of the painting is of 11 inches.

Answer:

There are two types of hypotheses tests. null and alternative

They are complements.

Step-by-step explanation:

There are two types of hypotheses tests. null and alternative

the table shows the summary of both tests.

True Situation                              DECISION

                                  Accept H0             Reject H0

                                                               (or accept Ha)

H0 is true          Correct decision       Wrong Decision

                            (no error)                     type I error          

H0 is false          Wrong Decision           Correct decision

                             type II error                 ( no error)    

The probability of making a type I error is conventionally denoted by alpha and that of committing a type II error is indicated by beta.

∝ = P ( type I error) = P (reject H0 / H0 is true)

β = P (type II error) = P (accept H0 / H0 is false)

When ∝ becomes larger, β tends to become smaller . There is inverse relationship between ∝ and β.

When H0 is true Ha is false when Ha is false H0 is true. So they are compliments of each other.

Step-by-step explanation:

The assumption of ANOVA are:

1)  the k- samples are selected randomly and independently from the respective populations

2) All the k population from which samples are drawn are normally distributed with means u1,u2, u3,........

3) the observations are random samples drawn from normally distributed populations with equal variances. The technical term for this assumption is Homoscedasticity.

Failure of any assumption will impair the technique. However, minor deviations can be tolerated. Sometimes square roots and logs are used to make assumptions true.
