So, it would be XZ/MN = 5/2

Answer:

[tex]Side\ 3 = 5p^2q + 3r[/tex]

Step-by-step explanation:

Given

[tex]Perimeter = 7p^2q + 13r[/tex]

[tex]Side\ 1 = 14r[/tex]

[tex]Side\ 2 = 2p^2q - 4r[/tex]

Required

Find the length of the third side

Perimeter is calculated as thus:

[tex]Perimeter = Side\ 1 + Side\ 2 + Side\ 3[/tex]

This gives:

[tex]7p^2q + 13r = 14r + 2p^2q - 4r + Side\ 3[/tex]

Collect like terms

[tex]Side\ 3 = 7p^2q - 2p^2q + 13r - 14r + 4r[/tex]

[tex]Side\ 3 = 5p^2q + 3r[/tex]

Answer:

18.99 or 19 when rounded

Step-by-step explanation:

[tex]8 = \frac{1}{3} (a + 5) \\ 8 = \frac{1a}{3} + 1.67 \\ 3 \times 8 = \frac{1a}{3} + 1.67 \times 3 \\ 24 = a + 5.01 \\ 24 - 5.01 = a + 5.01 - 5.01 \\ 18.99 = a[/tex]

Therefore a = 18.99

Answer:

Step-by-step explanation:

Answer:

A. Distance KL = 7.36 m

B. Height ML = 4.25 m

C. The maximum height is 6.96 m

Step-by-step explanation:

A. Determination of distance KL

Hypothenus = KM = 8.5 m

Angle θ = 30°

Adjacent = KL =?

Cos θ = Adjacent / Hypothenus

Cos 30 = KL / 8.5

0.866 = KL / 8.5

Cross multiply

KL = 0.866 × 8.5

KL = 7.36 m

Thus, the distance is 7.36 m

B. Determination of height (ML)

Hypothenus = KM = 8.5 m

Angle θ = 30°

Opposite = ML =?

Sine θ = Opposite /Hypothenus

Sine 30 = ML /8.5

0.5 = ML / 8.5

Cross multiply

ML = 0.5 × 8.5

ML = 4.25 m

Thus, the height is 4.25 m

C. Determination of the maximum height.

Hypothenus = KM = 8.5 m

Angle θ = 55°

Opposite = ML =?

Sine θ = Opposite /Hypothenus

Sine 55 = ML /8.5

0.8192 = ML / 8.5

Cross multiply

ML = 0.8192 × 8.5

ML = 6.96 m

Thus, the maximum height is 6.96 m

Answer:

The answer is "23, 62, and 139"

Step-by-step explanation:

In point a:

[tex]\to \sigma = \$0.24\\\\ \to E = \$0.10\\\\ 95\% \text{confidence level of the z}: \\\\\to \alpha = 1 - 95\% = 1 - 0.95 = 0.05\\\\\to \frac{\alpha}{2} = \frac{0.05}{2} = 0.025\\\\\to Z_{\frac{\alpha}{2}} = Z_{0.025} = 1.96\\\\[/tex]

 Calculating the sample size:

[tex]\to n = (\frac{(Z_{\frac{\alpha}{2}} \times \sigma)}{E})^2[/tex]

      [tex]= (\frac{(1.96 \times 0.24 )}{0.10})^2\\\\= 22.13 \approx 23[/tex]

In point b:

[tex]\to \sigma = \$0.24\\\\\to E = \$0.06\\\\\to Z_{\frac{\alpha}{2}} = Z_{0.025} = 1.96\\\\\to n = (\frac{(Z_{\frac{\alpha}{2}} \times \sigma )}{E})^2\\\\[/tex]

      [tex]= (\frac{(1.96 \times 0.24 )}{0.06})^2\\\\= 61.47 \approx 62[/tex]

In point c:

[tex]\to \sigma = \$0.24\\\\\to E =\$0.04\\\\\to Z_{\frac{\alpha}{2}} = Z_{0.025} = 1.96\\\\\to n = (\frac{(Z_{\frac{\alpha}{2}} \times \sigma )}{E})^2\\\\[/tex]

      [tex]= (\frac{(1.96\times 0.24 )}{0.04})^2 \\\\=138.30 \approx 139[/tex]    

Answer:

This is a function.

domain = [1, 6]

range = [1, 4]

Step-by-step explanation:

A relation that maps elements from one set (domain) into another set (input) is called a function only if each element of the domain is mapped into only one element in the range.

For a function y = f(x) the domain is the set of the possible x-values, and the range is the set of the possible y-values.

In this case we can see that the possible values of x is the interval [1, 6]

Where we have a closed interval because we have black dots, meaning that these values are included in the sets.

We also can see that the range is the interval [1, 4]

And we also can see that all the x-values are mapped into only one y-value, then this is a function.

Answer:

[tex] {8x}^{2} + 4x - 4[/tex]

Step-by-step explanation:

1) Use foil method: (a + b ) (c + d) = ac + ad + bc + bd.

[tex] {10x}^{2}+6x-5x-3-(2x-1)(x - 1)[/tex]

2) Use foil method: (a + b ) (c + d) = ac + ad + bc + bd.

[tex] {10x}^{2} + 6x - 5x - 3 - ( {2x}^{2} - 2x - x + 1[/tex]

3) Remove parentheses.

[tex] {10x}^{2} + 6x - 5x - 3 - {2x}^{2} - 2x - x + 1[/tex]

4) Collect like terms.

[tex]( {10x}^{2} - {2x}^{2} ) + (6x - 5x + 2x + x) + ( - 3 - 1)[/tex]

5) Simplify.

[tex] {8x}^{2} + 4x - 4[/tex]

Therefor, the answer is 8x² + 4x - 4.

Step-by-step explanation:

Hello There!

The first thing we want to do is find how much money we earn for washing 1 car

To do so we divide 5 (amount of cars washed) by the money we made from washing those 5 cars

35/5=7

so every car we wash we make 7 dollars

now we multiply the amount of money we make washing one car by 4

4x7=28

so we would earn $28 for washing 4 cars

Answer:

Option A

x + 2x + x + 15 = 100

Step-by-step explanation:

Shortest side = x

One side twice length of Shortest side = 2x

Another side 15 more = x + 15

Hence, perimeter

=> x + 2x + x + 15 = 100

The final statement is: The perimeter of the quadrilateral is given by 71 units.

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape

Given here: A quadrilateral ABCD with a circle inscribed in it.

Now sides of the quadrilateral form tangents from a common point (vertex)

Thus they must be equal

∴ Perimeter of the ABCD is = 29+12+2.5+2.5+21-17+21

                                              = 71 units

Hence, The perimeter of the quadrilateral is given by 71 units.
