determine the value of x? ​

Answer:

The difference between the area of the two circles is 15.7m

Step-by-step explanation:

I swear these be helping me with the CIEs coming up in May xD

Okay so the formula for a circle is [tex]\pi r^2[/tex]

The diameter is the double of the radius so

Cirlce A has a diameter of 4m so a radius of 2m

[tex]\pi 2^{2}[/tex]

[tex]\pi4[/tex]

[tex]12.57m[/tex]

Circle B has a diameter of 6m so a radius of 3m

[tex]\pi 3^2[/tex]

[tex]\pi 9[/tex]

[tex]28.27m[/tex]

To find the difference subtract 12.57 from 28.27

[tex]28.27-12.57\\=15.7[/tex]

The difference between the area of the two circles is 15.7m

Answer:

We need to see the other graph choices.  The line must go downhill since it's a negative slope (-x).  The line must cross at +2 on the y axis since 2 is the y intercept. Then from 2 you go down 1 box and to the right one box and put a point.  then draw the line

Answer:

Answer in attachment

Step-by-step explanation:

Ok so we have f(x)=-x+2

It can be written as y=-x+2, Keep in mind that the standard form of a line equation is y=mx+c where m is the gradient and c is the y intercept

the slope in our equation is equal to 1

The y-intercept is equal to the point (0,2) ----> value of the function f(x) when the value of x is equal to zero

The x-intercept is equal to the point (2,0)----> value of x when the value of the function is equal to zero

See the attachment for the answer :)

Hope it helps :)

➷ We can use that statement to form an equation:

2w - 7 = 8

Now we need to solve for w

Add 7 to both sides:

2w = 15

Divide both sides by 2:

w = 7.5

Answer:

15/2

Step-by-step explanation:

"7 less than the product of 2 and a number" comes out to 2w - 7.

This quantity equals 8:

2w - 7 = 8.

Adding 7 to both sides isolates 2w:

2w = 15

Dividing both sides by 2 yields

w = 15/2

Answer:

[tex]m<A.M.E=58\°[/tex]

Step-by-step explanation:

step 1

Find the measure of angle M.E.F

we know that

In an inscribed quadrilateral opposite angles are in fact supplements for each other

so

[tex]m<M.A.F+m<M.E.F=180\°[/tex]

[tex]m<M.E.F=180\°-75\°=105\°[/tex]

step 2

Find the measure of arc M.A.F

we know that

The inscribed angle measures half that of the arc comprising

so

[tex]m<M.E.F=\frac{1}{2}(arc\ M.A.F)[/tex]

we have

[tex]m<M.E.F=105\°[/tex]

substitute

[tex]105\°=\frac{1}{2}(arc\ M.A.F)[/tex]

[tex]arc\ M.A.F=210\°[/tex]

step 3

Find the measure of arc A.F

[tex]arc\ M.A.F=arc\ A.M+arc\ A.F[/tex]

we have

[tex]arc\ M.A.F=210\°[/tex]

[tex]arc\ A.M=125\°[/tex]

substitute

[tex]210\°=125\°+arc\ A.F[/tex]

[tex]arc\ A.F=210\°-125\°=85\°[/tex]

step 4

Find the measure of angle A.M.E

we know that

The inscribed angle measures half that of the arc comprising

so

[tex]m<A.M.E=\frac{1}{2}(arc\ A.F.E)[/tex]

we have

[tex]arc\ A.F.E=arc\ A.F+arc\ E.F=85\°+31\°=116\°[/tex]

substitute

[tex]m<A.M.E=\frac{1}{2}(116\°)=58\°[/tex]

The angle ∠AME is the angle subtended at the circumference by the arc [tex]m \widehat{EFA}[/tex].

Correct response:

The given parameters are;

[tex]m \widehat{AM}[/tex] = 125°

[tex]m\widehat{EF}[/tex] = 31°

m∠MAF = 75°

Required:

m∠AME

Solution:

[tex]m \widehat{MEF}[/tex] = 2 × m∠MAF

Therefore;

[tex]m \widehat{MEF}[/tex] = 2 × 75° = 150°

[tex]m \widehat{AM}[/tex] + [tex]m \widehat{MEF}[/tex] + [tex]m \widehat{FA}[/tex] = 360° sum of arcs of a circle postulate

Therefore;

[tex]m \widehat{FA}[/tex] = 360° - ([tex]\mathbf{m \widehat{AM}}[/tex] + [tex]\mathbf{m\widehat{MEF}}[/tex])

Which gives;

[tex]m\widehat{FA}[/tex] = 360° - (125° + 150°) = 85°

Therefore;

[tex]m\widehat{EFA}[/tex] = 85° + 31° = 116°

[tex]m \widehat{EFA}[/tex] = 2 × m∠AME (angle at center is twice angle at the circumference)

Therefore;

[tex]m\angle AME = \mathbf{\dfrac{m \widehat{EFA}}{2} }[/tex]

[tex]m \angle AME = \dfrac{116^{\circ}}{2} = 58^{\circ}[/tex]

Step-by-step explanation:

Length 1 side of the octagon.

The formula for the side of an octagon (given the radius of 6) is

s^2 = 2*R^2(1 - cos(45) )

s^2 = 2*6^2(1 - sqrt(2)/2)

s^2 = 72 ( 1 - 0.707)

The phrase commonly associated with division is 'the quotient of two numbers', highlighting it as the result of dividing one number by another.

The phrase usually associated with division is the quotient of two numbers. To give a brief explanation, division is the process of determining how many times one number is contained within another. This process results in the 'quotient'. For example, if we divide 10 by 2, we are essentially asking how many times 2 goes into 10, which would be 5 times. This result (5) is the quotient.

Another important aspect of division is that it is intimately connected to multiplication, as they are essentially inverse operations. Dividing by a number is the same as multiplying by its reciprocal. When working with scientific notation or complex numbers, the principles of division require additional rules, but the underlying concept of finding a quotient remains the same.

Answer:

Choice 4

Step-by-step explanation:

The parent function is [tex]y=x^3.[/tex] The graph of the function

In your case, the graph of the function [tex]f(x)=x^3-5[/tex] is translated 5 units down graph of the function [tex]y=x^3.[/tex] This is choice 4

Graph 4 is the correct graph of f(x) - 5.

To find the graph of f(x) - 5, we can start by graphing the graph of f(x) and then shifting it down by 5 units.

The graph of f(x) is a cubic function, which means that it is a graph of the form y = ax³ + bx² + cx + d. To graph a cubic function, we can use the following steps:

Find the x-intercepts of the graph. The x-intercepts are the points where the graph crosses the x-axis. To find the x-intercepts, we set y = 0 and solve the equation for x.

Find the y-intercept of the graph. The y-intercept is the point where the graph crosses the y-axis. To find the y-intercept, we set x = 0 and solve the equation for y.

Find the end behavior of the graph. As x approaches positive or negative infinity, what does the value of y approach?

Plot the x-intercepts, y-intercept, and any other important points on the graph.

Connect the points with a smooth curve.

To graph the graph of f(x) - 5, we simply shift the graph of f(x) down by 5 units.

The description matches  graph 4.

2w+6w=80

w=10

l=30

To find the length and width of the rectangle, we can set up an equation using the perimeter formula. Solving the equation will give us the values of the width and length.

Let's start by assigning variables to represent the length and width of the rectangle. Let's say the width is 'w' cm, so the length would be '3w' cm according to the information given.

The perimeter of a rectangle is given by the formula: P = 2(L + W), where P represents the perimeter, L represents the length, and W represents the width.

Substituting the given values into the formula, we can set up the following equation: 80 = 2(3w + w). Solving this equation will give us the value of 'w', which corresponds to the width of the rectangle. Once we have 'w', we can find the length by multiplying it by 3.

By solving the equation, we find that the width of the rectangle is 10 cm and the length is 30 cm.

Answer:

1/3 or letter c

Step-by-step explanation:

The spot of 1/3 in the equation f(x) = -2/3x + 1/3 is the same spot of b in the equation y = mx + b.

The correct value of y-intercept of the function f(x) = -2/3x + 1/3 is (0, 1/3).

To find the y-intercept of a function, you set x equal to zero and solve for y.

In the given function, f(x) = -2/3x + 1/3, we can find the y-intercept by substituting x = 0 into the equation:

f(0) = -2/3(0) + 1/3

f(0) = 0 + 1/3

f(0) = 1/3

Therefore, the y-intercept of the function f(x) = -2/3x + 1/3 is (0, 1/3).

The y-intercept of a function represents the point where the graph intersects the y-axis. To find the y-intercept, we set the value of x to zero and solve for the corresponding value of y.

In the given function f(x) = -2/3x + 1/3, we substitute x = 0:

f(0) = -2/3(0) + 1/3

Since any term multiplied by zero is zero, the first term becomes zero:

f(0) = 0 + 1/3

Adding 0 to any value doesn't change its value, so we are left with:

f(0) = 1/3

Therefore, the y-intercept of the function f(x) = -2/3x + 1/3 is (0, 1/3). This means that the graph of the function crosses the y-axis at the point (0, 1/3), where y equals 1/3.

Step-by-step explanation:

1. To graph the inequality y<3x-4, you need to plot dotted line y=3x-4 and then shade the part that doesn't contain the origin, because 0<3·0-4 is false statement. This is red region on the coordinate plane below.

2. To graph the inequality y≥-1/2x+3, you need to plot solid line y=-1/2x+3 and then shade the part that doesn't contain the origin, because 0≥-1/2·0+3 is false statement. This is blue region on the coordinate plane below.

3. The common part of two regions is the solution of the system of two inequalities.

To graph the system of linear inequalities, start by graphing the lines y = 3x - 4 and y = -1/2x + 3 as dashed lines. Then, shade the correct regions based on the inequality signs and find the overlap to determine the solution.

The given system of linear inequalities is:

y < 3x - 4

y ≥ -1/2x + 3

To graph these inequalities, we can start by graphing the lines y = 3x - 4 and y = -1/2x + 3 as dashed lines, since they are not included in the solution region.

Next, we can shade the correct region based on the inequality signs. For y < 3x - 4, we shade below the line, and for y ≥ -1/2x + 3, we shade above the line. The overlap of the shaded regions represents the solution to the system of inequalities.

Answer:

15 ft.

Step-by-step explanation:

If you divide the length of the drawing by the length of the real one you will find the scale factor. Every one cm in the drawing is 15 ft. in the real one.

One centimeter on the scale drawing represents approximately 0.03281 feet of the actual parking lot.

To find out how many feet of the parking lot are represented by 1 centimeter on the scale drawing, we need to use the conversion factor between centimeters and feet. Since 1 centimeter is equal to 0.01 meters (1 cm = 0.01 m) and 1 meter is equal to 3.281 feet (1 m = 3.281 ft), we can multiply the conversion factors together: 0.01 m * 3.281 ft/m = 0.03281 ft.

So, 1 centimeter on the scale drawing represents approximately 0.03281 feet of the actual parking lot.

The answer is 0.03.
