Can anyone help me with this?

The method can you ALWAYS use to solve the quadratic equation will be the Quadratic Formula method. Then the correct option is C.

The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.

A math question If an equation is written in standard form.

The factorization method sometimes gets difficult from the big number and in the case of the complex root. So, in that case, we use other methods.

In the Isolate the Square, we can find the roots of the equation. But the formula is also derived by this method. So, we do not even prefer this, method.

In this Quadratic Formula method, the formula is derived from the above method which is to Isolate the Square. Then this can be used always.

Equivalent expression are the expression whose result is equal to the original expression, but the way of representation is different.

Given information-

The expression given in the problem is,

[tex]\left((4^{\dfrac{5}{4}}\times4^{\dfrac{1}{4}}\div 4^{\dfrac{1}{2}} \right)^{\frac{1}{2}}[/tex]

im thinking its what your heart desiers

Step-by-step explanation:

Answer:

Step-by-step explanation:

The equation that allows determining the probability that the player wins the prize after n games is [tex]0.35^n[/tex] = Probability. The player should choose n = 10.

The simple definition of probability is the likelihood that an individual event will occur. It can be discussed the probabilities of distant outcomes, or how probable they are, whenever we're skeptical of how an occurrence will turn out. Statistics refers to the study of events subject to probability.

First, solve the following equation to find the likelihood of the player winning the prize after n games given that the probability of winning a specific game is 0.5 and that the player wins a prize if at least 70[tex]\%[/tex] of the games in a series are won.

[tex]Probability = 0.5^n \times 0.70[/tex]

[tex]Probability = 0.35^n[/tex]

It is evident here that the larger the value of n, the lesser the chances to win.

For example, if there were five games played, the equation would be as follows:

[tex]0.35^5 = 0.005[/tex]

So. the value of n chosen by the player should be 10.

The complete question is as follows:

The probability of winning a certain game is 0.5. If at least 70 percent of the games in a series of n games are won, the player wins a prize. If the possible choices for n are n = 10, n = 20, and n = 100.

Which value of n should the player choose in order to maximize the probability of winning a prize?

Plug 30 back in to solve for y

Answer:

The number is 4.

Step-by-step explanation:

Let the number be x,

11 + 5x = 31

or, 5x = 31 - 11

or, 5x = 20

or, x = 20/5

so, x = 4

Answer:

Graph A

Step-by-step explanation:

The y-intercept is -3, which is the y-value when the graph hits the y-axis.

Graph A and B both hit the y-intercept of -3.

The slope is 3/4, which means the line rises 3 units as it runs 4.

This time, only Graph A has the correct slope.

The correct answer is [tex]\boxed{\text{Graph A}}[/tex]

-Chetan K

Answer:

Graph A

Step-by-step explanation:

The formula is in the form y=mx+c, where m is the gradient and m is the y-intercept, this means that the y-intercept is (0,-3) which rules out Graph B.

To find the gradient we use [tex]\frac{rise}{run}[/tex], this means that the vertical value has to be 3 and the horizontal distance 4 and this rules out Graph C as its gradient is 3/2. That means that graph A matches the equation the best.

Answer: z = [tex]\sqrt{10}[/tex]

Step-by-step explanation:

To find z, you must set up a proportion to solve.

To find the altitude of a special right triangle, the formula is:

[tex]\frac{a}{x} =\frac{x}{b}[/tex]

You can use 5 as a and 2 as b to complete the proportion:

[tex]\frac{5}{z} =\frac{z}{2}[/tex]

Next, to solve:

Step 1: Cross-multiply.

[tex]\frac{5}{z} =\frac{z}{2}[/tex]

(5)*(2) = z*z

10 = z²

Step 2: Take square root.

10 = z²

√10 = z

Answer:

x = 83.7 units

Step-by-step explanation:

Using cosine rule:

→ adjacent/hypotenuse = cos(∅)

→ 56/hypotenuse = cos(48)

→ hypotenuse = 56/cos(48)

→ hypotenuse = 83.7 units

Answer:

83.7

Step-by-step explanation:

We can solve this using SOHCAHTOA:

RQ is adjacent to angle Q and x is the hypotenuse, so we must use the cosine function.

[tex]cosQ = \frac{RQ}{SQ}\\ cos(48) = \frac{56}{x}\\ x = \frac{56}{cos(48)}\\ x = 83.7[/tex]

Answer:

The side length for A and B is 30 and the side length for B and D is 16, in the new dilated rectangle. The reason we multiplied by 2 is because 2 is greater than 1, and this means the image is an enlargement.

Step-by-step explanation:

Dilation is where the polygon grows or shrinks but keeps the same overall shape. A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement (think stretch) is a dilation that creates a larger image. If the scale factor is between 0 and 1 the image is a reduction. If the scale factor is greater than 1, the image is an enlargement. This means that the image, A’, is twice as large as the pre-image A. This means that the image, A’, is twice as large as the pre-image A.

Since 2 is greater than 1, the image is an enlargement

So we do 2*15 and 2 * 8

And we get

30 and 16

The side length for A and B is 30 and the side length for B and D is 16.

Answer:

See, that doesn't make sense.

First of all, 4 is the only number equal to 4. Sp, it'd be 9+4 = 13

Answer:

49

Step-by-step explanation:

First, you need to solve for x.

88 = 5x + 34 + 8x 15

88 = 13x + 49

88 - 49 = 13x

39 = 13x

39/13 = x

3 = x

Now substitute 3 in place of x to find rps

rps = 5x+34

rps = 5*3 + 34

rps = 15 + 34

rps = 49
