The total cost is T(x)={ 90x if 0≤x≤2, 180+50x if x > 2}

Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression.

An algebraic expression in algebra is formed using integer constants, variables, and basic arithmetic operations of addition(+), subtraction(-), multiplication(×), and division(/).

Given:

T(x)={a if x≤2, b if x > 2}

let us take

a= 90x, 0≤x≤2

and, b = 180 + 50x  for x>2

Answer:

y = (-2/3)x + 16/3

Step-by-step explanation:

Any line parallel to y = (-2/3)x has the same slope:  (-2/3).

Then, in this pattern, y = (-2/3)x + c, where c is the y-intercept.

If (4, -8) lives on this new line, then:

-8 = (-2/3)(4) + c, and

-8 = -8/3 + c

This last equation is equivalent to -24/3 + 8/3 + c  => -16/3 = -c.

Therefore the y-intercept is 16/3 = c, and the desired equation is

y = (-2/3)x + 16/3

Step-by-step explanation:

Let's simplify step-by-step.

8y−2(y+4)

Distribute:

=8y+−2y+−8

Combine Like Terms:

Answer:

6y - 8

Step-by-step explanation:

This is a simplifying problem, so we just need to separate and link the like terms.

First we start with the parenthesis by distributing

-2*y + -2*4

-2y - 8

We can the put it back into the equation

8y - 2y + 8

8y and -2y are like terms so we can put them together to get 6y

The mean repair cost for the stereos is (79.47, 91.56) with a 90% confidence interval.

The critical factor for a 90% confidence interval for the true mean repair cost for stereos is given by;

Critical factor = (x-μ)/(s/√n)

where, x = sample mean repair cost

s =  standard deviation of a sample

n = sample of stereos

μ  = critical value

We have been given that a researcher records the repair cost for 13 randomly selected stereos. a sample mean of $⁢85.52 and a standard deviation of $10.81 are subsequently computed.

Since we don't know the population standard deviation, we used t statistics to create the 90% confidence interval in this case.

So, the 90% confidence interval for the true mean repair cost, μ is ;

⇒ P(-2.015 < t₅ < 2.015) = 0.90  

{As the critical value of t at 5 degrees of  freedom are -2.015 & 2.015 with P = 5%}

⇒ P(-2.015 < (x-μ)/(s/√n) < 2.015) = 0.90

⇒ P(-2.015×(s/√n) < (x-μ) < 2.015×(s/√n)) = 0.90

⇒ P(x - 2.015×(s/√n) < μ < x + 2.015×(s/√n)) = 0.90

90% confidence interval for

⇒ μ = (x - 2.015×(s/√n) , x + 2.015×(s/√n))

Here, x = $85.52, s  = $10.81, and n = 13

⇒ μ = (85.52 - 2.015×(10.81/√13) , 85.52 + 2.015×(10.81/√13))

⇒ μ = (79.47, 91.56)

Step-by-step explanation:

You want the base segment lengths KI and PR, given relations between those segments and the corresponding midsegment of the triangle.

A midsegment is a line segment that joins midpoints of other line segments, usually the midpoints of triangle sides or opposite sides of a quadrilateral. In the case of a triangle, the midsegment is parallel to the third side, and half its length. This relation is used to solve these problems.

  KI = 2·AB

Additional comment

As you can see here, there is no real reason to find the value of x, then substitute it back into the expression for the segment of interest. We can, and did, solve directly for the value of that expression.

As with any algebraic manipulation, any operation performed on one side of the equal sign must also be performed on the other side of the equal sign. When we say "subtract ()", we mean "subtract () from both sides of the equation."

In problem 11, x=-9. In problem 12, x=-8. Negative values of x work just fine, as long as the resulting segment lengths are positive.

The equations of the lines in the form y=mx+b are-

A line's slope is described like the change in y coordinate to the change in x coordinate. The net y coordinate change is y, whereas the net x coordinate change is x.

Therefore the variation in y coordinate in relation to the variation in x coordinate is written as, dy/dx.

Now, as per the given conditions;

The equation of the line is y = (6 + 4x)²

Simplifying the equation;

y = (6 + 4x)²

  = 36 + 48x + 16x²

y = 16x² + 48x + 36

Now, differentiate the equation to find the tangent slope;

dy/dx = 32x + 48

At the point (6,900),

dy/dx = 32(6) + 48 = 240

Let equation of the tangent at point (a,b) is;

(y - b) = m(x - a)

a = 6, b = 900, m = 240

y - 6 = 240(x - 900)

Write this in y = mx + b form,

y - 6 = 240x - 216000

y = 240x - 215994 (Equation of Tangent line)

The slope of the normal line = -(1/slope of the tangent line) (since they're both perpendicular to each other)

Slope of the normal line = -1/240

The, equation of the normal will become;

y - 6 = (-1/240)(x - 900)

y - 6 = (-x/240) + 3.75

y = (-1/240)x + 9.75

y = - 0.00417x + 9.75 (Equation of Normal line)

The Washington Monument is an obelisc and the volume of the obelisc is the sum of the volumes of the square frustrum and the pyramid, that is:

V = V' + V''                                             (1)

Yes, the pole will fit in the box when kept diagonally.

In order to fit the pole in rectangular prism or cuboid, it has to be kept diagonally. Now, we need to calculate the length of body diagonal of cuboid. The length of body diagonal of cuboid should be greater than pole to fit it.

The length of body diagonal of cuboid can be calculated by the formula -

Diagonal = √(l² + b² + h²)

Keep the values in formula to find the diagonal of rectangular prism

Diagonal = √(10² + 9² + 8²)

Taking square of the three numbers to find the diagonal of rectangular prism

Diagonal = √100 + 81 + 64

From the attached figure, we have the following coordinates

A = (5, 16)

B = (17, 10)

C = (14, 4)

D = (2, 10)

Calculate the lengths AB and BC using the following distance formula

d = √[(x2 - x1)^2 + (y2 - y1)^2]

This gives

AB = √[(5- 17)^2 + (16- 10)^2] = 13.4

BC = √[(14- 17)^2 + (4- 10)^2] = 6.7

The approximate length of string lights the staff needs to decorate the ceiling is then calculated as
