Answers

Answer:

y = 125x + 775

Step-by-step explanation:

you can make coordinate points (x, y) from the graph

x = Number of hours

y = Total Charge

(1, 800) and (2, 925)

slope from 2 points = y2-y1/x2-x1

x1 = 1

y1 = 800

x2 = 2

y2 = 925

925 - 800/2-1 = 125/1

m = 125

using y = mx + b, where m = 125,  and 1 of the coordinate points you can find the y intercept

multiply 125 times 2

925 = 250 + b

subtract 250 from both sides

b = 675

y = 125x + 675

There are 20 students in Mrs. Williams' class, and 1/5 of the class has their own cellphone. Of this group of students, 1/2 of them are allowed to use social media. How many of the students have a
cellphone and can use social media?

Answers

Answer:

2

Step-by-step explanation:

Only 1/5 of Miss Williams' class has a cell phone, so we work this out by dividing the number of students by 5

20÷5=4

Out of this group of 4 students, only 1/2 are allowed to use social media

4÷2=2

This means that only 2 pupils have a phone and are allowed to use social media at the same time.

If you need to express this in fraction form, it would be 1/10 of the class

[tex]\frac{d^2y}{dx^2} = \frac{-300y^2}{(4y^3-11)^3}[/tex]

Step-by-step explanation:

Given the expression  [tex]y^4+5x=11y[/tex], we are to find the second derivative [tex]\frac{d^2y}{dx^2}[/tex]

This differentiation will be implicit (indirect) as shown:

[tex]4y^3 \frac{dy}{dx} + 5 = 11\frac{dy}{dx} \\4y^3 \frac{dy}{dx} - 11 \frac{dy}{dx} = -5\\\frac{dy}{dx}(4y^3-11) = -5\\\frac{dy}{dx} = \frac{-5}{4y^3-11}[/tex]

Differentiating the second time using quotient rule:

[tex]\frac{d^2y}{dx^2} = \frac{4y^3-11 (0)- (-5)12y^2\frac{dy}{dx} }{(4y^3-11)^2} \\\\\frac{d^2y}{dx^2} = \frac{60y^2\frac{dy}{dx} }{(4y^3-11)^2} \\\\\frac{d^2y}{dx^2} = \frac{60y^2(\frac{-5}{4y^3-11} ) }{(4y^3-11)^2}\\\\\frac{d^2y}{dx^2} = \frac{-300y^2}{(4y^3-11)^3}[/tex]

6(8-2x)=4x what is the answer to this equation?​

Answers

Answer:

x=3

Step-by-step explanation:

6(8−2x)=4x

Step 1: Simplify both sides of the equation.

6(8−2x)=4x

(6)(8)+(6)(−2x)=4x(Distribute)

48+−12x=4x

−12x+48=4x

Step 2: Subtract 4x from both sides.

−12x+48−4x=4x−4x

−16x+48=0

Step 3: Subtract 48 from both sides.

−16x+48−48=0−48

−16x=−48

Step 4: Divide both sides by -16.

−16x/−16=−48/−16

Answers

Answer:

d. the means of two or more populations are equal

Step-by-step explanation:

ANOVA is a short term for analysis of variance and it was developed by the notable statistician Ronald Fisher. It is typically a collection of statistical models with their respective estimation procedures used for the analysis of the difference between the group of means found in a sample. Simply stated, ANOVA helps to ensure we have a balanced data by splitting the observed variability of a data set into random and systematic factors. In Statistics, the random factors doesn't have any significant impact on the data set but the systematic factors does have an influence.

The ANOVA procedure is a statistical approach for determining whether or not the means of two or more populations are equal through the use of a F-test or null hypothesis.

Solution (5) :

Let the missing angle be ∠y . Then :-

∠y =∠115°

Their measure will be equal as they are alternate interior angles whose angle measure will be equal when on two parallel lines with a transversal .

Therefore , the missing angle = 115° .

Solution (6) :

Let the missing angle be ∠x . Then :-

∠x = ∠66°

Their measure will be equal as they alternate interior angles .

Therefore , the ,measure of the missing angle is = 66° .

Solution (7) :

Let the missing angle be ∠m . Then :-

∠m + ∠50° = 180°

∠m = 180 - 50

∠m = 130°

The sum of these two angles will be equal to 180° as they are interior angles on the same side of transversal .

Therefore , the measure of the missing angle will be = 130° .

Solution (8) :

Let the missing angle be ∠n . Then :-

∠n + ∠105° = 180°

∠n = 180 - 105

∠n = 75°

The sum of these two angles will be will be equal to 180° as they are interior angles on the same side of transversal .

Therefore , the measure of the missing angle will be = 75° .

Answer:

(-8,-5)

Step-by-step explanation:

Answer:

-5x+y=35x-2y=2

Rewrite it, {-5x+y=2, 3x-2y=2}

Multiply both sides of the first equation by 2, {-10x+2y=4, 3x-2y=2}

Eliminate a variable, -7x=6

Divide both sides by -7, x=-6/7

Substitute the value of x, 3(-6/7)-2y=2

Possible solution, y=-16/7

Now to check the solution, (x, y)=(-6/7, -16/7)

It needs to equal 180, and 180-138 is 42

Answer:

The answer is D: 42

Step-by-step explanation:

Angle 7 and angle 138 are supplementary and must add up to 180

Angle 7 is congruent to angle 6 through CPCTC (Corresponding Parts of Congruent Triangles are Congruent)

Angle 7 and 6 are corresponding angles

you must find angle 7 becasue Angle 7= Angle 6

angle 7=x

138-x=180

solve for equation you get

x=42

Angle 7 = 42

so that means that Angle 6 is 42

Which function has a zero with a multiplicity of 2?

Answers

Answer:p(x)=(x-1)(x-3)²

Step-by-step explanation:

The polynomial p(x)=(x-1)(x-3)² is a 3rd degree polynomial, but it has only 2 distinct zeros. This is because the zero x=3, which is related to the factor (x-3)², repeats twice. This is called multiplicity. It means that x=3 is a zero of multiplicity 2, and x=1 is a zero of multiplicity 1.

If the measure of ∠2 is 83°, what is the measure of ∠3?

Answers

Answer:

97 degress

Step-by-step explanation:

2 and 3 form a supplementary angle, meaning the sum of their angles should equal 180.

The measure of ∠3 is 97°.

What are supplementary angles?

If two angles add up to 180 degrees, they are considered supplementary angles. When combined, supplementary angles form a straight angle of 180 degrees. In other words, if Angle 1 + Angle 2 equals 180 degrees, angles 1 and 2 are added together. Angles 1 and 2 are referred to as "supplements" of one another in this instance.

Given two lines intersect and form angles

∠1, ∠2, ∠3, ∠4

and ∠2 = 83°

here ∠2 and ∠3 form supplementary angles,

them ∠2 + ∠3 = 180°

83 + ∠3 = 180

∠3 = 180 - 83

∠3 = 97°

Hence measure of ∠3 is 97°.
