Answer:

If Khalfan is 30 inches, he is 2.5 feet

Step-by-step explanation:

1 foot is 12 inches, so to get closest to 30, you double 12 to 24, and then you add another 6 inches, which is half of 1 foot, and there you go! You're welcome!

13)

from F to J it's 6 steps in x-direction and 3 steps in y-direction (up)

3/6 = 0.5

from J to H it's -2 steps in x-direction (to the left) and -4 steps in y-direction (down)

-4/-2 = 2

from G to H it's 6 steps in x-direction and 7 steps in y-direction (up)

7/6 = 1.1666666

14)

FG and JH are parallel

FJ and GH are parallel as well

meaning same slope

the other combinations are perpendicular (see screenshot)

15)

my brain needs rest. but just a hint: solve via pythagorean theorem, find the distance in x direction, and in y direction, then use a²=b²=c²

hope it gives you something

Answer:

[tex]g^-^1(x)=-8[/tex]

[tex]h^-^1(x)=\frac{x-4}{3}[/tex]

[tex](h^-^1 \ o\ h)(-3)=-3[/tex]

Step-by-step explanation:

When given the following functions,

[tex]g=[(-2,-7),(4,6),(6,-8),(7,4)][/tex]

[tex]h(x)=3x+4[/tex]

One is asked to find the following,

1. Question 1

[tex]g^-^1(4)[/tex]

When finding the inverse of a function that is composed of defined points, one substitutes the input given into the function, then finds the output. After doing so, one must substitute the output into the function, and find its output. Thus, finding the inverse of the given input;

[tex]g^-^1(4)[/tex]

[tex]g(4)=6\\g(6)=-8\\g^-^1(4)=-8[/tex]

2. Question 2

[tex]h^-^1(x)[/tex]

Finding the inverse of a continuous function is essentially finding the opposite of the function. An easy trick to do so is to treat the evaluator (h(x)) like another variable. Solve the equation for (x) in terms of (h(x)). Then rewrite the equation in inverse function notation,

[tex]h(x)=3x+4\\\\h(x)-4=3x\\\\\frac{h(x)-4}{3}=x\\\\\frac{x-4}{3}=h^-^1(x)[/tex]

[tex]h^-^1(x)=\frac{x-4}{3}[/tex]

3. Question 3

[tex](h^-^1 \ o\ h)(-3)[/tex]

This question essentially asks one to find the composition of the function. In essence, substitute function (h) into function ([tex]h^-^1[/tex]) and simplify. Then substitute (-3) into the result.

[tex]h^-^1\ o\ h[/tex]

[tex]\frac{(3x+4)-4}{3}\\\\=\frac{3x+4-4}{3}\\\\=\frac{3x}{3}\\\\=x[/tex]

Now substitute (-3) in place of (x),

[tex]=-3[/tex]

Answer:

32.2

Step-by-step explanation:

Given :

f(x) = x² +9

P(x) = f(x) - 34 ÷ x + 5

P(5) =?

Substitute 5 for X on P(x)

P(5) = f(5) - 34 ÷ x + 5

f(5) = 5² + 9 = 25 + 9 = 34

P(5) = 34 - 34 ÷ 5 + 5

According to PEMDAS

-34 ÷ 5 = - 6.8

P(5) = 34 - 6.8 + 5

P(5) = 34 - 1.8

P(5) = 32.2

Answer:

  349

Step-by-step explanation:

In Roman numerals, C=100, L=50, X=10, V=5, I=1. Values are additive except when a lower value precedes a higher value. In that case, the lower value is subtracted.

The value here is 10 -1 +50 -10 +100 +100 +100 = 349.

__

Additional comment

Letters are assigned to 1 and 5 and those values multiplied by 10 or 100. When you get to 4000 and above, special forms apply. By convention, only unit values within a factor of 10 are subtracted. In the above number, 49 is written XLIX, not IL.

Step-by-step explanation:

Angles of triangles add up to 180

x=180-57-51

x=72

Answer:

[tex]x=12[/tex]

Step-by-step explanation:

By definition, supplementary angles add up to 180 degrees. Therefore, we can set up the follow equation to solve for [tex]x[/tex]:

[tex]10x+60=180,\\10x=120,\\x=\boxed{12}[/tex]

Answer:

x=12

Step-by-step explanation:

Supplementary angles add up to 180 degrees.

10x+60=180

Subtract 60 from both sides:

10x=120

Divide 10 to both sides:

x=12

Answer:

a. μ = 25

b. σ = 16.496

Step-by-step explanation:

Note: See the attached excel for the calculation of Mean and Deviation from Mean.

Let: N = Number of observation = 9

F = Frequency

Therefore, we have:

a. Compute the expected number of arrivals per minute. μ=___( please type as an integer or a decimal)

From the attached excel file, we have:

Total F = 200

Therefore, we have:

μ = Mean = Total of F / (N - 1) = 200 / (9 - 1) = 25

b. Compute the standard deviation σ=___(please round to three decimal places as needed)

From the attached excel file, we have:

Total (F -  μ)^2 = 2,177

σ = Standard deviation = (Total of (F -  μ)^2 / (N - 1))^0.5 = (2,177 / (9 - 1))^0.5 = 16.496

A regular polygon is a polygon that has all sides and all angles equal.

Each interior angle, k (measured in degrees), of a regular polygon is given by;

k = s ÷ n            -----------(k)

Where;

s = sum of the interior angle of the polygon.

n = number of sides of the polygon

To get s, we use

s = (n - 2) x 180         [This is the formula to calculate the sum of the interior angles of a polygon]

Substituting s this into equation (i) gives

k = (n - 2) x 180 ÷ n

k = 180(n - 2) ÷ n             -------------(ii)

(a) Triangle.

A triangle has n = 3 sides, therefore, each interior angle of a triangle is found by substituting n = 3 into equation (ii)

k = 180(3 - 1) ÷ 3

k = 180(2) ÷ 3

k = 180 x 2 ÷ 3

k = 360 ÷ 3

k = 120°

Convert to grade.

Remember that;

90° = 100 grades

∴ 120° = [tex]\frac{120 * 100}{90}[/tex] grades

⇒ 120° = 133.33 grades.

Therefore, each interior angles of a regular triangle is 120° or 133.33 grades.

(b) Quadrilateral.

A quadrilateral has n = 4 sides, therefore, each interior angle of a quadrilateral is found by substituting n = 4 into equation (ii)

k = 180(4 - 1) ÷ 4

k = 180(3) ÷ 4

k = 180 x 3 ÷ 4

k = 540 ÷ 4

k = 135°

Convert to grade.

Remember that;

90° = 100 grades

∴ 135° = [tex]\frac{135 * 100}{90}[/tex] grades

⇒ 135° = 150 grades.

Therefore, each interior angles of a regular quadrilateral is 135° or 150 grades.

k = 180 x 4 ÷ 5

k = 720 ÷ 5

k = 144°

Convert to grade.

Remember that;

90° = 100 grades

∴ 144° = [tex]\frac{144 * 100}{90}[/tex] grades

⇒ 144° = 160 grades.

Therefore, each interior angles of a regular pentagon is 144° or 160 grades.

k = 900 ÷ 6

k = 150°

Convert to grade.

Remember that;

90° = 100 grades

∴ 150° = [tex]\frac{150 * 100}{90}[/tex] grades

⇒ 150° = 166.67 grades.

Therefore, each interior angles of a regular hexagon is 150° or 166.67 grades.

(e) Heptagon

A heptagon has n = 7 sides, therefore, each interior angle of a heptagon is found by substituting n = 7 into equation (ii)

k = 180(7 - 1) ÷ 7

k = 180(6) ÷ 7

k = 180 x 6 ÷ 7

k = 1080 ÷ 7

k = 154.29°

Convert to grade.

Remember that;

90° = 100 grades

∴ 154.29° = [tex]\frac{154.29 * 100}{90}[/tex] grades

⇒ 154.29° = 171.43 grades.

Therefore, each interior angles of a regular heptagon is 154.29° or 171.43 grades.

(f) Octagon

An octagon has n = 8  sides, therefore, each interior angle of a octagon is found by substituting n = 8 into equation (ii)

k = 180(8 - 1) ÷ 8

k = 180(7) ÷ 8

k = 180 x 7 ÷ 8

k = 1260 ÷ 8

k = 157.5°

Convert to grade.

Remember that;

90° = 100 grades

∴ 157.5° = [tex]\frac{157.5 * 100}{90}[/tex] grades

⇒ 157.5° = 175 grades.

Therefore, each interior angles of a regular octagon is 157.5° or 175 grades.

k = 180(8) ÷ 9

k = 180 x 8 ÷ 9

k = 1440 ÷ 9

k = 160°

Convert to grade.

Remember that;

90° = 100 grades

∴ 160° = [tex]\frac{160 * 100}{90}[/tex] grades

⇒ 160° = 177.78 grades.

Therefore, each interior angles of a regular nonagon is 160° or 177.78 grades.

(h) Decagon

A decagon has n = 10 sides, therefore, each interior angle of a decagon is found by substituting n = 10 into equation (ii)

k = 180(10 - 1) ÷ 10

k = 180(9) ÷ 10

k = 180 x 9 ÷ 10

k = 1620 ÷ 10

k = 162°

Convert to grade.

Remember that;

90° = 100 grades

∴ 162° = [tex]\frac{162 * 100}{90}[/tex] grades

⇒ 162° = 180 grades.
