Step-by-step explanation:

Solution is in the attached photo, do note this question tests on finding the area of shapes.

It is been proved that (a² + b²)(c² + d²) = (ac + bd)² + (bc - ad)².

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
(a)

(a² + b²)(c² + d²) = (ac + bd)² + (bc - ad)²

LHS,
= a²(c² + d²)  + b² (c² + d²)
= a²c² + a²d² + b²c² + b²d²
= a²c² + b²d² + 2abcd + b²c² + a²d² - 2abcd
= (ac + bd)² + (bc - ad)²
= RHS

Thus, it is been proved that (a² + b²)(c² + d²) = (ac + bd)² + (bc - ad)².

Step-by-step explanation:

No, rectangle DABC is not the result of a dilation of rectangle HEFG with a center of dilation at the origin.

Dilation is a geometrical transformation that changes the size of a shape or figure. It is one of the four basic transformations of geometry alongside translation, rotation, and reflection. Dilation involves resizing a shape by a scale factor and keeping its overall shape intact. The scale factor is the ratio of the size of the image to the size of the original figure.

Dilation involves a scaling of a shape, where each point on the shape is moved away from or closer to the center of dilation, proportional to its distance from the center. In this case, the angles of rectangle DABC are different from the angles of rectangle HEFG, so it is not the result of a dilation. The angles of rectangle HEFG are ∠2, ∠33, ∠EDC, whereas the angles of rectangle DABC are ∠ADB, ∠BDC, and ∠CDB.

Step-by-step explanation:

A z-score can be calculated using the formula z = (x-)/, where x is the raw score, the mean of the population, and the standard deviation of the population.

The z-score is simply the raw score minus the mean of the population divided by the standard deviation of the population, as the formula demonstrates.

Typically, z-scores, or standardized scores, are calculated by dividing the mean of all data points by the standard deviation of all data points, then subtracting the mean from each individual data point. Again, using scale(), this can be done in one call.

He wants 4500

He makes 1700 salary

4500-1700=2800

The length of the diagonal KM is 8√(2) inches.

The area of a square is given by the formula: area = side^2.

So, if the area of square JKLM is 64 square inches, then we know that:

64 = side^2

To find the diagonal KM, we can use the Pythagorean Theorem. The diagonal KM is the hypotenuse of a right triangle where the legs are the side of the square.

So the formula is KM = √(side^2 + side^2)

Substituting in the known area of the square, we have:

KM = √(64 + 64)

KM = √(128)

KM = 8√(2)

Therefore, the length of the diagonal KM is 8√(2) inches.

What does a math equation mean?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Revenue: r(x) = 10x, so r(2000) = 10(2000) = $20,000

Costs: c(x) = 3x + 9000, so c(2000) = 3(2000) + 9000 = $15,000

b) The profit function, p(x), is the difference between the revenue function and the cost function. So, the profit function for this company is:

p(x) = r(x) - c(x) = 10x - (3x + 9000) = 7x - 9000

c) To find the company's profit in 2012, when it sold 5000 shirts, we substitute 5000 for x in the profit function:

p(5000) = 7(5000) - 9000 = $20,000

So, the company had a profit of $20,000 in 2012 when it sold 5000 shirts.

Answer:

y = 8

Step-by-step explanation:

The angle represented by (8x - 31)° = angle represented by (6x + 3)° since they are alternate interior angles

8x - 31 = 6x + 3

=> 8x-6x = 3 + 31

2x = 34

x = 17

Angles (8x - 31) and (5y + 35) are adjacent linear angles - they lie on the same straight line. their sum must equal 180

8x - 31 + 5y + 35 = 180

Plugging x = 17

8(17) -31 + 5y + 35 = 180

5y + 140 = 180

5y = 180 - 10 = 40

y = 40/5 = 8

6 * 4 = 24

5 * 2 = 10

24 + 10 = 34

6 + 5 = 11

Answer:

6 goats and 5 ducks

Step-by-step explanation:

Given: g+d=11

Goats have 4 legs. Ducks have 2 legs. For total of 34 legs.

Use the word problem to create equation: 4g+2d=34

We can solve for either, we'll solve for g(goat) first:

4g+2d=34

2d=34-4g

d=17-2g

Plug what we found for d into other equation:

g+d=11

g+(17-2g)=11

-g+17=11

-g=-6

g=6

Plug what we found for g into equation to solve for d(duck):

g+d=11

The surjective function is defined with reference to the elements of the range set, such that every element of the range is a co-domain.

A surjective function is a function whose image is equal to its co-domain, and every element y can be mapped from element x so that f(x) = y.

it suffices to give an example of y∈Z such that f(x)=y has no solutions. Just pick y=−2 and derive that

The annual interest rate on the loan is 0.02 or 2%.

To find the annual interest rate on the loan, we need to use the formula for simple interest:

I = Prt

where:

I is the interest,

P is the principal (the amount of the loan),

r is the annual interest rate (expressed as a decimal),

t is the time in years

We know the following information:

I = $240

P = $4000

t = 3

We can use this information to set up the equation and solve for r:

240 = 4000 * r * 3

240 = 12000r

r = 240/12000

r = 0.02

Answer:

x = 77°

Step-by-step explanation:

When an angle has its vertex on a circle, the arc that gets cut by sides is double the angle.

So arcDF is double angleEFD.

angleEFD = 74°

arcDF = 148°

arcFH is double angleD.

angleD = 29°

arcFH = 58°

All the arcs of the circle all add up to 360°

arcDF + arcFH + arcDH = 360°

148° + 58° + arcDH = 360°

206 + arcDH = 360°

subtract 206

arcDH = 154°

Again, the arc is double the angle, or the angle is half the arc.

arcDH = 154°

angleDFH = 77°

x = 77°
