Answer:

(p+13)(p+1)

Step-by-step explanation:

p² + 14p + 13

we want to find two numbers that add to 14 and multiply to 13

we can start looking by listing the factors of 13

we get 13 and 1 and -13 and -1

13 and 1 multiply to 13 ( 13 × 1 = 13 ) and add to 14 ( 13 + 1 = 14 )

-13 and -1 multiply to 13 ( -13 × -1 = 13 ) and add to -14 ( -13 + -1 = -14 )

the two numbers that would add to 14 and multiply to 13 would be 13 and 1

now we can factor out the two numbers from 14 and split the p from p² to get (p+13)(p+1)

and we are done

Split up the region into shapes whose areas are easy to find. (see attached; this is not the only choice of partitioning the figure)

• The larger rectangle has area

(13 ft) × (7 ft) = 91 ft²

• The smaller rectangle has area

(11 ft) × (2 ft) = 22 ft²

• The triangle has area

1/2 × (3 ft) × (3 ft) = 4.5 ft²

Then the total area of the figure is 91 ft² + 22 ft² + 4.5 ft² = 117.5 ft².

The area of the Logo 1 will be 12.48 square meters and the area of the Logo 2 will be 9.6 square meters.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Now consider the logos for Parkside Printing shown.

Determine the actual area of Logo 1  and Logo 2 in square meters will be

The area of the Logo 1 (A₁) will be

[tex]\rm A _1 = 12 \times 8 - 6 \times 3\\\\A_1 = 78 \ cm^2\\\\A_1 = 78 \times 0.16 \ m^2\\\\ A_1 = 12.48 \ m^2[/tex]

Then the area of the Logo 2 (A₂) will be

[tex]\rm A_2 = \dfrac{1}{2} \times 12 \times 10\\\\A_2 = 60 \ cm^2\\\\A_2 = 60 \times 0.16 \ m^2\\\\A_2 = 9.6 \ m^2[/tex]

Step-by-step explanation:

calculate the slope m of the 2 points from the origin and equate, since they lie on the same line

m = [tex]\frac{y_{2}-y_{1} }{x_{2-x_{1} } }[/tex]

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (2, k )

m = [tex]\frac{k-0}{2-0}[/tex] = [tex]\frac{k}{2}[/tex]

repeat with

(x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = k, 32 )

m = [tex]\frac{32-0}{k-0}[/tex] = [tex]\frac{32}{k}[/tex]

equating the 2 slopes

[tex]\frac{k}{2}[/tex] = [tex]\frac{32}{k}[/tex] ( cross- multiply )

The rectangular equivalence of the parametric equations is given as:
an ellipse that is focalized on (2, -5) with semi-major axis of 4 and semi-minor axis of 2.

A parametric equation is the type which has dependent variables defined as a continuous function of the independent factor - t, and the dependent variables are mutually exclusive of other existing variables.

Step 1 - Note that we have the following terms:

x(θ)=4cosθ+2,

y(θ)=2sinθ−5

Step 2 - Rewrite the above equations

x = 4 -cos(θ) +2;

y = 2 -Sin (θ) - 5

We rewrite again as

[tex]\left( \frac{x-2}{n}\right)^{2}[/tex] = cos (θ)²;        [tex]\left( \frac{y+5}{n}\right)^{2}[/tex] = sin(θ)²

Recall that

cos (θ)² + sin(θ)² = 1

Therefore,

[tex]\left( \frac{x-2}{n}\right)^{2}[/tex]  + [tex]\left( \frac{y+5}{n}\right)^{2}[/tex] = 1

The result is an ellipse with the center  (2, -5) with a semi-major axis of 4 and a semi-minor axis of 2. See the result of the Parametric Graph Plot attached.

Answer:

2y=5x-2

Write the equation in the form of y = mx + b

where m is the gradient and b is the y-intercept.

Therefore, 2y=5x-2 will be:

y = 5/2x - 1

Gradient is 5/2

and y-intercept is (0,-1)

The slope as evaluated from the given pair of points is; Slope, m = 5.

Slope of given Points

The slope of a line defined by two points simply refers to the rate of change of the function given by the line.

Hence, slope, m = (28 -18)/(4 -2)

The square root of 112 by division method is 4√7

To answer the question, we need to know what square root is

The square root of a number is a number which multiplies itself to give us the given number.

Now, to find the square root of 112 by division method, we divide 112 through by successive prime numbers until we can divide no more.

So, 112 ÷ 2 = 56

56 ÷ 2 = 28

28 ÷ 2 = 14

14 ÷ 2 = 7

So, 112 = 2 × 2 × 2 × 2 × 7

112 = 2⁴ × 7

So, √112 = √(2⁴ × 7)

√112 = √2⁴ × √7

√112 = 2² × √7

√112 = 4 × √7

√112 = 4√7

So, square root 112 by division method is 4√7

Answer: 56 kids

Step-by-step explanation: 70 * 0.2 = 14      70 - 14 = 56

Last year we tested 70 kids on Unit 8 and this year we tested 20% less kids then we tested 56 kids on Unit 8 this year.

percentage, a relative value indicating hundredth parts of any quantity.

If we tested 20% less kids this year, it means we tested only 80% of the number of kids we tested last year.

To find out how many kids we tested this year, we can use the following equation:

number of kids tested this year = 0.8 × number of kids tested last year

Substituting the given values, we get:

number of kids tested this year = 0.8 × 70

number of kids tested this year = 56

Therefore, we tested 56 kids on Unit 8 this year.
