What is the solution to 4|0. 5x – 2. 5| = 0? x = 1. 25 x = 5 x = –1. 25 or x = 1. 25 x = –5 or x = 5.

Answer:

[tex]x=-7,x=-1,x=-0.289898,x=0.689898[/tex]

or [tex]x=-7,x=-1,x=\frac{1}{5}-\frac{\sqrt{6}}{5},x=\frac{1}{5}+\frac{\sqrt{6}}{5}[/tex]

Step-by-step explanation:

Factor by grouping

[tex]g(x)=5x^4+38x^3+18x^2-22x-7\\\\g(x)=5x^4+33x^3-15x^2-7x+5x^3+33x^2-15x-7\\\\g(x)=x(5x^3+33x^2-15x-7)+1(5x^3+33x^2-15x-7)\\\\g(x)=(x+1)(5x^3+33x^2-15x-7)\\\\g(x)=(x+1)(5x^3+35x^2-2x^2-14x-x-7)\\\\g(x)=(x+1)(5x^2(x+7)-2x(x+7)-1(x+7))\\\\g(x)=(x+1)(x+7)(5x^2-2x-1)\\\\0=(x+1)(x+7)(5x^2-2x-1)\\[/tex]

We can easily see that the first two zeroes are [tex]x=-1[/tex] and [tex]x=-7[/tex], however, the third zero will need the help of the quadratic formula:

[tex]0=5x^2-2x-1\\\\x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\x=\frac{-(-2)\pm\sqrt{(-2)^2-4(5)(-1)}}{2(5)}\\\\x=\frac{2\pm\sqrt{4+20}}{10}\\ \\x=\frac{2\pm\sqrt{24}}{10}\\ \\x=\frac{2\pm2\sqrt{6}}{10}\\ \\x=\frac{2}{10}\pm\frac{2\sqrt{6}}{10}\\ \\x=\frac{1}{5}\pm\frac{\sqrt{6}}{5}\\\\x_1\approx0.689898\\\\x_2\approx-0.289898[/tex]

Therefore, the zeroes of the function are [tex]x=-7,x=-1,x=-0.289898,x=0.689898[/tex]

The explanation:

8x+36x-24=

44x-24.

That is in its simplest form.

Answer:

44x-24

Step-by-step explanation:

First we can multiply 6 by 4.

6 x 4 = 24

Then we multiply 8x by -6x

-6x × 8x = -48

Lastly we subtract 4 from -48, and turn it into a positive number.

48 - 4 = 44

Answer:

AB = 45

Step-by-step explanation:

If ΔABC is an isoceles triangle, then 2 sides are equal in length.

From the diagram, we can see that AC = BC (the dashes mean the sides are of equal length).

Therefore, equate AC and BC, then solve for x:

                                                 AC = BC

                                            3x + 9 = 4x + 4

Subtract 3x from both sides:      9 = x + 4

Subtract 4 from both sides:        5 = x

So x = 5

Now we know that x = 5, we can substitute this into the expression for AB to find AB:

   AB = 8x + 5

⇒ AB = (8 x 5) + 5

⇒ AB = 40 + 5

⇒ AB = 45

Answer:

1/2 or 0.5

Step-by-step explanation:

Since this question is asking for an estimate, you have to round 2.8 to the nearest whole number. 2.8 is closer to 3 rather than 2. Since 6 is already a whole, divide 3 by 6, which is 1/2 or 0.5. If you were to solve this problem without estimating, you would get 0.4666666666, which rounds to 0.5, but the question asks for an estimate.

Answer:

x = 20

Step-by-step explanation:

The 3 angles lie on a straight line and sum to 180° , that is

3x + 80 + 2x = 180

5x + 80 = 180 ( subtract 80 from both sides )

5x = 100 ( divide both sides by 5 )

x = 20

Answer:

Here,3x°+80°+2x=180° [Angles on a line]

or,3x°+2x°+80°=180°

or,5x°+80°=180°

or,5x°=180°-80°

or,5x°=100°

or,x°=100/5

Therefore,x°=20°

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

Probability that exactly 4 students have taken chemistry Thus the option C is the correct option.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

Given information-

Mrs. Gomes found that 40% of students at her high school take chemistry.

Mrs. Gomes randomly surveys 12 students.

Total number of students who have taken chemistry in surveys is 4.

As the 40 percent of students at her high school take which is equal to the 0.4. Thus the percent of students who is not at her high school,  is equal to the,

[tex]=1-0.4\\=0.6[/tex]

As the total number of surveyed students is 12 and the number of chemistry student is 4 in the surveyed students. Thus the probability of this event can be given as,

[tex]=P(1)+P(2)+P(3)+P(4)\\=\sum_{0}^{4}C_r(0.4)^r(0.6)^{12-r}[/tex]

Put the values in the above equation we get the probability equals to the 0.213.

Hence, probability that exactly 4 students have taken chemistry Thus the option C is the correct option.

To solve the problem we must know about the correlation coefficients.

The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.

The correlation coefficient 0.715 denotes, "There is a strong positive relationship between x and y".

Given to us

As we can see that the value of the correlation coefficient is 0.715, therefore, it is close to 1 means the relationship is strong, while the '+' symbol denotes that the relationship is positive.

Hence, the correlation coefficient 0.715 denotes, "There is a strong positive relationship between x and y".

The value of the equation is p = ( m/2 ) + 4

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

m = 8 - 2 ( p - m )   be equation (1)

On simplifying the equation , we get

m = 8 - 2p + 2m

Subtracting m on both sides of the equation , we get

m + 8 - 2p = 0

Adding 2p on both sides of the equation , we get

2p = m + 8

Divide by 2 on both sides of the equation , we get

p = ( m/2 ) + 4

Hence , the equation is p = ( m/2 ) + 4

Answer:

I think it's 69.

Step-by-step explanation:

Break them up into 2 figures. The first is 6 x 7 = 42. The second is 3 x 9 because they say each meter on the bottom is 3, and there's is 3 of them so 3 x 3 = 9. Continuing, 3 x 9 = 27. So, 42 +  27 = 69.

So, 69 is the answer.
