The value of the composite functions of h(g(x)) is h(g(x)) = -20x + 6.

In mathematics, a function is composed when two functions, f and g, are used to create a new function, h, such that h(x) = g(f(x)). The function of g is being applied to the function of x, in this case. Therefore, a function is essentially applied to the output of another function.

Given that, h(x) = 4x + 6 and g(x) = -5x.

The value of h(g(x)) is calculated by substituting x = -5x in the equation of h(x).

h(g(x)) = 4(-5x) + 6

h(g(x)) = -20x + 6

Hence, the value of the composite functions of h(g(x)) is h(g(x)) = -20x + 6.

The length of side DF is 5 units.

If two figures possess the same shape but not necessarily the same size, they are considered to be similar. We may remark that all circles are similar as an example. Equilateral triangles and squares are similar to one another. Although similar figures need not be congruent, all congruent figures are similar.

Property 1:

Two triangles are similar if their respective sides have the same ratio and their corresponding angles are equal.

Property 2:

The corresponding angles of two similar triangles will have equal values . Equiangular triangles are what they are called.

Step-by-step explanation:

The length of side AB within quadrilateral ABCD is 14.301 meters.

In this problem we find a geometric system formed by a quadrilateral and two diagonals, whose parameters are listed below:

CD = 20 m

m ∠ BCD = 20°

m ∠ ACB = 40°

m ∠ ADC = 45°

m ∠ ADB = 50°

The missing side can be found by combining law of sine and law of cosine:

Law of sine

20 / sin 65° = BD / sin 20°

BD = 7.548

20 / sin 75° = AD / sin 60°

AD = 17.932

Law of cosine

AB = √(AD² + BD² - 2 · AD · BD · cos ADB)

AB = √(17.932² + 7.548² - 2 · 17.932 · 7.548 · cos 50°)

The required trigonometric ratios are as follows: sin t = 1/2 and cos t = √3/2.

Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.

According to the given figure, we have a right triangle ΔABC which has:

AB = 1/2

BC = √3/2

CA = AB² + BC²

CA = √(1/2)² + (√3/2)²

CA = √1/4 + 3/4

CA = √4/4 = 1

As we know that the trigonometric ratios are as follows:

sin (180°- t) = AB/CA

sin t = (1/2)/1

sin t = 1/2

cos (180°- t) = BC/CA

cos t = (√3/2)/1

The average rate of change of the function over the interval (-1, 2) is 3.

Average rate of change of a function is defined as the rate at which the value of the function is changing with respect to the change in the input values.

Difference quotient of a function over an interval is also the same concept as the average rate of change of a function.

Average rate of change of a function f(x) over an interval (a, b) is [tex]\frac{f(b) - f(a)}{b-a}[/tex].

Given interval is (-1, 2).

From the graph, f(-1) = -4 and f(2) = 5

Average rate = [tex]\frac{f(2) - f(-1)}{2--1}[/tex] = (5 - -4) / (3) = 9/3 = 3

Answer:

Step-by-step explanation:

Here's a step by step explanation of how to calculate the number of cakes baked if the bakery baked 96 loaves of bread:

First, determine the number of sets of 12 loaves of bread that were baked:

96 loaves of bread ÷ 12 loaves per set = 8 sets of 12 loaves

Next, determine the number of cakes baked for each set of 12 loaves of bread:

For every set of 12 loaves, 5 cakes are baked.

Finally, multiply the number of sets by the number of cakes baked per set to find the total number of cakes baked:

8 sets × 5 cakes per set = 40 cakes

So, if the bakery baked 96 loaves of bread, they would have baked 40 cakes.

Answer:

40

Step-by-step explanation:

12 times 8 equals 96 and 5 times 8 equals 40, there for 40 cakes will be backed

Answer:

To find the coefficient of variation (CV) of a sample, we divide the standard deviation by the mean and multiply by 100 to get the percentage.

1. For the systolic sample:

•Find the mean:

mean = (116 + 130 + 157 + 94 + 155 + 122 + 115 + 138 + 124 + 122) / 10 = 130

•Find the standard deviation:

sum = (116 - 130)^2 + (130 - 130)^2 + (157 - 130)^2 + (94 - 130)^2 + (155 - 130)^2 + (122 - 130)^2 + (115 - 130)^2 + (138 - 130)^2 + (124 - 130)^2 + (122 - 130)^2

sum = 165.4

std = sqrt(sum/9) = 7.3

•Calculate the coefficient of variation:

CV = (std / mean) × 100 = (7.3 / 130) × 100 = 5.62%

2. For the diastolic sample:

•Find the mean:

mean = (82 + 78 + 74 + 51 + 89 + 88 + 56 + 63 + 72 + 83) / 10 = 72.5

•Find the standard deviation:

sum = (82 - 72.5)^2 + (78 - 72.5)^2 + (74 - 72.5)^2 + (51 - 72.5)^2 + (89 - 72.5)^2 + (88 - 72.5)^2 + (56 - 72.5)^2 + (63 - 72.5)^2 + (72 - 72.5)^2 + (83 - 72.5)^2

sum = 624.75

std = sqrt(sum/9) = 12.24

•Calculate the coefficient of variation:

CV = (std / mean) × 100 = (12.24 / 72.5) × 100 = 16.82%

So the CV for systolic is 5.62% and the CV for diastolic is 16.82%. We can see that the diastolic measurement has higher variation than the systolic measurement.

Answer:

a = 5, b = 5√3

Step-by-step explanation:

Use sin law

sin A/a = sin C/c

sin 30/a = sin 90/10

sin 30/(sin90/10) = a

a = 5

sin B/b = sin C/c

sin 60/b = sin 90/10

sin 60/(sin90/10) = b

b = 5√3

The area of the triangle with side lengths 28 and 21 and an angle of 118 degrees is 260 squared unit.

A triangle is simply a two-dimensional polygon with 3 sides and 3 interior angles.

The area of a triangle can be determine using the formula;

A = ( a × b × sin( C ) ) / 2

From the diagram;

Plug the given values into the above formula.

A = ( a × b × sin( C ) ) / 2

A = ( a × m × sin( R ) ) / 2

A = ( 28 × 21 × sin( 118° ) ) / 2

A = ( 588 × sin( 118° ) ) / 2

A = ( 588 × 0.8829 ) / 2

A = 519.17 / 2

A = 260 square unit.
