Answer:

[tex]Volume = 7x^3y+48x^2y^2-7xy^3 -35x^2-240xy-35y^2[/tex]

Step-by-step explanation:

Given

Shape: Cube

Dimension: (x+7y), (7x-y) and (xy-5).​

Required

Determine the volume

The volume is calculated by multiplying the dimensions:

[tex]Volume = (x+7y) * (7x-y) * (xy-5)[/tex]

Evaluate the first 2 brackets

[tex]Volume = [x(7x-y)+7y(7x-y)] * (xy-5)[/tex]

[tex]Volume = [(7x^2-xy)+(49xy-7y^2)] * (xy-5)[/tex]

[tex]Volume = [7x^2-xy+49xy-7y^2] * (xy-5)[/tex]

[tex]Volume = [7x^2+48xy-7y^2] * (xy-5)[/tex]

Open brackets

[tex]Volume = xy[7x^2+48xy-7y^2] -5[7x^2+48xy-7y^2][/tex]

[tex]Volume = 7x^3y+48x^2y^2-7xy^3 -35x^2-240xy-35y^2[/tex]

Twice the sum of a number and seven

a) 2(x+7)

Answer:

78.42

Step-by-step explanation:

Area of 360 - 80 degree region.

You need to find out the region of the major arc where the circle is almost complete. The area left over will be calculated later

Angle = 360 -80

Angle = 280 degrees.

Area = [tex]\frac{angle*3.14*r^2}{360}[/tex]

Area = [tex]\frac{280*3.14*5^2}{360}[/tex]

Area = 23800/360

Area = 66.11

Area of the Triangle with sides of 5 cm each

Here's where I get into a bit of trouble. I have to assume you know some trig.

Find the height

Cos(40) = The height / the hypotenuse

Cos(40) =  h/5

0.7760 = h/5

h = 0.7760*5

h = 3.830

Find 1/2 the base (the chord of the circle)

Sin(40) = 1/2 base / hypotenuse

Sin(40) =  1/2 b / 5                          Multiply both sides by 5

1/2 b = 5*sin(40)                              Find the sin(40)

1/2 b = 5*.6428                               Combine the right

1/2 b = 3.139                                    multiply by 2

b = 6.4278

Find the area of the triangle

Area = 1/2 b * h

b = 6.4278

h = 3.830

Area = 1/2 * 6.4278*3.830

Area = 12.31 cm^2

Total Area

12.31 + 66.11 = 78.42

Answer:

We can apply the straight-line method to solve for the value of the computer every year.

Step-by-step explanation:

Step one:

What is depreciation?

It can be defined as the loss of value of a commodity.

In this problem, the percent depreciation is given as 20% which means that 20% of the worth of the computer is lost every year.

We are told that the computer cost is $1000

let the number of years taken for the computer to depreciate be x

Step two:

Say we want to find the value of the computer after 1 year, the value of the computer will be

Value of computer= 1000-20/100*1000

Value of computer= 1000-0.2*1000

Value of computer= 1000-200

Value of computer= $800

Step three:

For the second year, the value will be

Value of computer= 800-20/100*800

Value of computer= 800-0.2*800

Value of computer= 800-160

Value of computer= $640

Answer:

This situation represents exponential decay. The rate of growth or decay, r, is equal to 0.2. So the value of the computer each year is 80% of the value in the previous year. It will take 3 years for the value of the computer to reach $512.

Congruent Triangles

Two triangles are said to be congruent if their sides have the same length and angles have same measure. Thus, two triangles can be superimposed side to side and angle to angle.

The transformed function g(x) = |x + 9| - 5 has a vertex at (- 9, - 5).

We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.

In piecewise terms  | x | = x for x ≥ 0 and | x | = - x for x < 0.

Given, The parent function is f(x) = |x|.

Now, The transformed function g(x) = |x + 9| - 5 is shifted x + 9 = 0 ⇒ x = - 9 units along the x-axis and - 5 units along the y-axis.

The vertex of the modulus function is at (- 9, - 5).

Answer:

500πx³y³z³

Step-by-step explanation:

Volume of a sphere = 4πr³

r is the radius of the sphere

Given

Diameter of the sphere = 10xyz mm

Radius = diameter/2

Radius = 10xyz/2

Radius = 5xyz

Substitute the radius into the formula

Volume of the sphere = 4π(5xyz)³

Volume of the sphere = = 4π(125)x³y³z³

Volume of the sphere = 500πx³y³z³

Hence the volume of the sphere is 500πx³y³z³ mm³

Answer:

[tex]1/2[/tex]

Step-by-step explanation:

We are given the line:

[tex]3x-6y=18[/tex]

And we want to find the slope of the line parallel to this given line.

Remember that parallel lines have the same slope. So, if we can determine the slope of the given line, we have the slope of its parallel line.

To determine the slope of the given line, we simply have to isolate the y. So, we can first divide everything by 3. This yields:

[tex]x-2y=6[/tex]

Adding 2y to both sides yields:

[tex]x=6+2y[/tex]

And subtracting 6 from both sides yields:

[tex]x-6=2y[/tex]

Finally, dividing everything by 2 gives us:

[tex]\displaystyle y=\frac{1}{2}x-3[/tex]

Hence, the slope of our line is 1/2.

So, the slope of the line parallel to this line must also be 1/2.

Answer:

Yes, his expectation is reasonable

Step-by-step explanation:

Mathematically;

1 mile = 1.609344 km

If he runs this in 5 minutes;

his speed will be 1.609344/5 = 0.3219 km/m

Now he intends breaking the record of 5 kilometers in 15.25 minutes

Distance = speed * time

What we shall have in this case will be;

15.25 * 0.3219 = 4.908

Approximately this is 5 km

So we can conclude that he will break the record if he runs at this speed
