Answer:

In Euclidean plane geometry, a tangent line to a circle is a line that touches the circle at exactly one point, never entering the circle's interior. Tangent lines to circles form the subject of several theorems, and play an important role in many geometrical constructions and proofs.

Explanation

Part (a)

The smaller pyramid up top is the result of slicing at the halfway point.

This leads to the ratio 1:2 when comparing small side to larger side.

Cube both parts of that ratio to end up with 1:8 as the volume ratio.

This means if the smaller pyramid was say 1 cubic foot in volume, then the larger pyramid has a volume of 8 cubic feet.

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

Part (b)

Consider the case that,

The volume of the truncated base is 8-1 = 7 cubic feet.

The ratio of the smaller pyramid to the truncated base is 1:7

Step-by-step explanation:

We can let d represent the number of hours that Dylan volunteered. Then Tadeo volunteered for 6d hours, and their total hours were ...

  d +6d = 14

  7d = 14 . . . . . . collect terms

  d = 2 . . . . . . . divide by the coefficient of d

  6d = 6(2) = 12

Tadeo volunteered 12 hours; Dylan volunteered 2 hours.

Answer:

Equation: y = 2x + 25

Step-by-step explanation:

Here x determines the number of year. For the first year,we will see ( 2 * 1 ) = $2 increase. In the second year, ( 2 * 2 ) =$4 increase and like this goes on, whereas the $25 being constant. "y" determines the total cost for each year.

Therefore the equation can be made: y = 2x + 25

Answer:

3x - 23 = 2828

Step-by-step explanation:

I'll assume the question is supposed to read "The sum of three times a number (x) and −23 is 2828."

"three times a number (x)" can be written as 3x

"sum of three times a number (x) and −23" means 3x - 23

"is 2828"  = 2828

Put them together:

3x - 23 = 2828

Answer:

Step-by-step explanation:

The 2 factors of x^2 - 9x + 14 are (x - 7) and (x - 2) because -7 + -2 = -9 and -7 x -2 = 14.

The factors of the quadratic expression  x² – 9x +  14 is (x - 7)(x - 2) option (B) (x - 2) is correct.

Any function of the form [tex]\rm f(x) =ax^2+bx+c[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic function.

It is given that:

The quadratic expression is:

= x² – 9x +  14

Using factor method:

= x² – 7x - 2x +  14

= x(x - 7) - 2(x - 7)

= (x - 7)(x - 2)

The factors of the quadratic expression  x² – 9x +  14 is (x - 7)(x - 2)

Thus, the factors of the quadratic expression  x² – 9x +  14 is (x - 7)(x - 2) option (B) (x - 2) is correct.

Answer:

B = (3, -5)

D = (0, -1)

C = (3, 5)

Step-by-step explanation:

We want to find the coordinates of B, C, and D given that AB = 5 and BC = 10.

Because AB = 5 and BC = 10, we can find the slope of the line using the slope formula:
[tex]\displaystyle \begin{aligned} m & = \frac{\Delta y}{\Delta x} \\ \\ & = \frac{(10)}{(5)} \\ \\ & = 2 \end{aligned}[/tex]

Point A(-2,-5) is on the line. Hence, the equation of the line is:
[tex]\displaystyle \begin{aligned} y-y_1 &= m(x-x_1) \\ \\& = y-(-5) = 2(x-(-2)) \\ \\ y + 5 & = 2x+4 \\ \\ y & = 2x-1 \end{aligned}[/tex]

Because AB is 5, B is simply A shifted rightwards five units. Hence:

[tex]\displaystyle B = (-2+5, -5) = (3, -5)[/tex]

At Point D, x = 0. Hence:
[tex]\displaystyle y = 2(0) -1 = -1[/tex]

Thus, D is at (0, -1).

B and C are collinear. Hence, the x value of C is 3:

[tex]\displaystyle y = 3(2) - 1 = 5[/tex]

Therefore, C is at (3, 5).

The systems of equations are known to be complex. We often use systems of equations in real-world scenario such as when calculating or thinking if one will make more money at one job than the other, here we look into variables such as wages, benefits and commissions, etc.

They  are used to calculate the amount of tax that is charge to people. They also help man to measure and understand the real- world situations and happenings.

The field or career that Equations are known to be widely used are the engineering profession. Chemical engineers, civil engineers, electrical engineers, etc. often uses it in construction of building, lighting a place, etc.

The Systems of equations are often applied in the real world by economists and entrepreneurs to known the time of equality of supply and demand.

Answer:

2x[tex]x^{2}[/tex]-8x+2

Step-by-step explanation:

Using proportions, it is found that 8 more seventh graders are involved in the yearbook.

A proportion is a fraction of a total amount.

Researching the problem on the internet, it is found that 10% of the 6th graders and 18% of the 7th graders are on the yearbook, hence:

0.1 x 280 = 28 6th graders.

0.18 x 200 = 36 7th graders.

36 - 28 = 8

8 more seventh graders are involved in the yearbook.
