Answer:

the first choice is not a polynomial because you can't divide by a variable.

Answer:

42 cm

Step-by-step explanation:

The first rectangle has a length of 4 and a Width of 7. the second rectangle has a length of 2 and a width of 7.

The formula for area of a rectangle is A=l*w

SO,

Rectangle 1: A= L*W

A=4*7

A=28

Rectangle 2:

A=L*W

A=2*7

A=14

Now, add both areas since they are both part of one whole recatngle.

28+14

= 42

[tex]\textsf{Perimeter of a semicircle}=r(\pi +2) \quad \textsf{(where r is the radius)}[/tex]

Use the above formulas to calculate the various measurements, remembering to calculate the radius first when given the diameter.

a) Radius = 2.7 cm

[tex]\implies \textsf{Area}=\sf \pi (2.7)^2=22.9\:\:cm^2\:(1\:d.p.)[/tex]

[tex]\implies \textsf{Circumference}=\sf 2 \pi (2.7)=17.0\:\:cm\:(1\:d.p.)[/tex]

-----------------------------------------------------------------------

b)  Diameter = 45 mm

[tex]\sf \implies Radius =\dfrac{45}{2}=22.5\:\:mm[/tex]

[tex]\implies \sf Area= \pi (22.5)^2=1590.4\:\:mm^2\:(1\:d.p.)[/tex]

[tex]\implies \sf Circumference= 2 \pi (22.5)=141.4\:\:mm\:(1\:d.p.)[/tex]

a)  Radius = 8.5 cm

[tex]\implies \sf Area=\dfrac{1}{2}\pi (8.5)^2=113.5\:\:cm\:(1\:d.p.)[/tex]

[tex]\sf \implies Perimeter=8.5(\pi +2)=43.7\:\:cm\:(1\:d.p.)[/tex]

-----------------------------------------------------------------------

b)  Radius = 24 mm

[tex]\implies \sf Area=\dfrac{1}{2}\pi (24)^2=904.8\:\:mm\:(1\:d.p.)[/tex]

[tex]\sf \implies Perimeter=24( \pi +2)=123.4\:\:cm\:(1\:d.p.)[/tex]

-----------------------------------------------------------------------

c)  Diameter = 32 cm

[tex]\sf \implies Radius =\dfrac{32}{2}=16\:\:cm[/tex]

[tex]\implies \sf Area=\dfrac{1}{2}\pi (16)^2=402.1\:\:cm\:(1\:d.p.)[/tex]

[tex]\sf \implies Perimeter=16( \pi +2)=82.3\:\:cm\:(1\:d.p.)[/tex]

d)  Diameter = 15 m

[tex]\sf \implies Radius =\dfrac{15}{2}=7.5\:\:m[/tex]

[tex]\implies \sf Area=\dfrac{1}{2}\pi (7.5)^2=88.4\:\:m\:(1\:d.p.)[/tex]

[tex]\sf \implies Perimeter=7.5( \pi +2)=38.6\:\:m\:(1\:d.p.)[/tex]

Answer:

The answer is below :

The missing number given the mean of the data set is 16.

Mean is the average of a data set. It is determined by adding all the numbers in the data set and dividing the sum by the numbers in the data set.

Missing number = (mean x total number in the data set) - sum of numbers in the data set

(18 x 7) - ( 21 + 11 + 27 + 22 + 13 + 16)

-3x -2y - 4 = 19

-3x - 2y = 23

2x + y - 6 = -20

2x + y = -14

The statement correctly describes the graph of y = ln(x - 7) + 3 is translated 3 units up as well as 7 units to the right.

The graph of a logarithmic function has a vertical asymptote at x = 0. The graph of a logarithmic function will decrease from left to right

if 0 < b < 1. And if the base of the function is greater than 1, b > 1, then the graph will increase from left to right.

Given graph : y = ln(x), has a vertical and horizontal translation.

As we know, y = ln(x - h) + k | where h is the vertical shift, and k is the horizontal shift.

Therefore, comparing y = ln(x - 7) + 3 it with different function we can write the graph of y = ln(x - 7) + 3 is translated 3 units up as well as 7 units to the right.

Taking into account the definition of ratio and proportion, the airline should sell 440 tickets.

The ratio is the comparison of two quantities and is measured from the division of two values.

The relationship of equality that exists between two ratios, that is, between two comparisons between two determined quantities, is known as a proportion. So if [tex]\frac{a}{b}[/tex] corresponds to the ratio, then [tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex] equals a proportion.

An airplane flight has 374 seats. The probability that a person who buys a ticket actually goes on that flight is about 85%. The airline wants to fill all the seats (100%) on the flight.

This can be represented by the proportion:

[tex]\frac{374}{85}[/tex] = [tex]\frac{amount of tickets}{100}[/tex]

Solving:

amount of tickets= 100×[tex]\frac{374}{85}[/tex]

amount of tickets= 440

Finally, the airline should sell 440 tickets.

The height of a woman whose femur (f) measures 49 centimeters is equal to 173.15‬ centimeters.

A function can be defined as a mathematical expression that defines and represents the relationship that exists between two or more variable of a data set.

In order to determine the height of a woman whose femur (f) measures 49 centimeters, we would substitute this numerical value into the first function as follows:

G(f) = 2.57f + 47.22

G(49) = 2.57(49) + 47.22

G(49) = 125.93 + 47.22

From the information given, vehicle A has a final sale price of $25,000 at 5% interest and financing up to 60 months. The interest will be:

= (25000 × 5 × 5)/100

= $6250

Vehicle B has a final sale price of $29,000 at 4% interest and financing up to 60 months. The interest will be:

= (29000 × 4 × 5)/100

Answer:

The rule for a rotation by 180° about the origin is (x,y)→(−x,−y).

Step-by-step explanation:

The rotation of angle 180 degree about origin is described below.

Rotation 180° about the origin is a geometric transformation that involves rotating a figure or shape around the point (0,0),

Also known as the origin, by an angle of 180 degrees.

This means that every point on the shape is moved to an equal distance away from the origin but on the opposite side of the origin.

This transformation is a reflection where the shape is flipped along,

the x-axis or y-axis or both, depending on the shape's orientation.

The rotation 180° about the origin is a common transformation in various geometrical applications, such as computer graphics, engineering, and physics.

It is a simple transformation that can be easily represented and performed using matrices or complex numbers.

Therefore,

rotation 180° about the origin is a geometric transformation that is important in various applications and involves rotating a shape around the origin by an angle of 180 degrees, resulting in a reflection of the shape across the x or y-axis.

Question 2.1.1

Reason:

Use the distance formula to find the distance from the origin (0,0) to the terminal point (-3, 4)

[tex](x_1,y_1) = (0,0) \text{ and } (x_2, y_2) = (-3,4)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(0-(-3))^2 + (0-4)^2}\\\\d = \sqrt{(0+3)^2 + (0-4)^2}\\\\d = \sqrt{(3)^2 + (-4)^2}\\\\d = \sqrt{9 + 16}\\\\d = \sqrt{25}\\\\d = 5\\\\[/tex]

The pythagorean theorem is a similarly related alternative path you can take.

This triangle is a 3-4-5 right triangle.

====================================================

Question 2.1.2

Reason:

r = distance from origin to terminal point

r = 5, calculated back in the previous problem above.

sin(alpha) = y/r = 4/5

cos(alpha) = x/r = -3/5

sin(alpha)+cos(alpha) = (4/5)+(-3/5) = 1/5

====================================================

Question 2.1.3

Reason:

Recall that tangent is the ratio of sine over cosine

tan = sin/cos

Therefore,

[tex]\tan(\alpha) *\frac{\cos(\alpha)}{\sin(\alpha)}\\\\\frac{\sin(\alpha)}{\cos(\alpha)}*\frac{\cos(\alpha)}{\sin(\alpha)}\\\\\frac{\sin(\alpha)*\cos(\alpha)}{\cos(\alpha)*\sin(\alpha)}\\\\1[/tex]

This assumes that neither sin(alpha) nor cos(alpha) are zero. Otherwise, we have a division by zero error.

Answer:

  612.5 cm²

Step-by-step explanation:

The ratio of areas of similar figures is the square of the scale factor. The scale factor is the ratio of corresponding side lengths. Here, we must find the scale factor.

__

The only given side of trapezium B corresponds to an unknown side of trapezium A. We can find the length of that unknown side using the area formula.

  A = 1/2(b1 +b2)h . . . . . parallel sides b1, b2; height h

  98 cm² = 1/2(16 cm +b2)(7 cm) . . . . use known values

  28 cm = 16 cm +b2 . . . . . . . . . . divide by 3.5 cm

  b2 = 12 cm . . . . . . . . . . . . . . subtract 16 cm

The top side of trapezium A is 12 cm long.

Now we have the lengths of corresponding (top) sides, so we can find the scale factor. It is their ratio. We choose to express it as (size of B)/(size of A).,

  k = (30 cm)/(12 cm) = 2.5

The area of trapezium B will be that of trapezium A multiplied by the square of the scale factor:

  area B = (k²)(area A) = (2.5²)(area A)

  area B = 6.25×98 cm² = 612.5 cm²

The area of trapezium B is 612.5 cm².

Then the maximum profit is got when 2 employees earn overtime.

We also need to find the maximum for the table. Notice that the maximum value of the table also happens for x = 2, and this time the maximum is y = 16.
