The measures of the exterior angles are:

a = 80°

b = 115°

c = 40°

d = 50°

e = 75°

The sum of the measure of an interior angle and the correspondent exterior angle is always 180°, then we can write:

a + 100° = 180°

a = 180° - 100° = 80°

b + 65° = 180°

b = 180° - 65° = 115°

c + 140° = 180°

c = 180° - 140°  =40°

d + 130° = 180°

d = 180° - 130° = 50°

e + 105° = 180°

e = 180° - 105° = 75°

These are the angles.

Answer:

Step-by-step explanation:

You want the values that complete the table when y is inversely proportional to the cube of x.

A proportional relation has the form ...

  y = kx

where k is the constant of proportionality.

If y is inversely proportional to x, that is the same as saying y is proportional to the inverse of x:

  y = k(1/x)

Here, y is proportional to the inverse of the cube of x:

  y = k/x³

The value of k can be found as ...

  k = x³·y = (10³)(0.6) = 600

So the relation to use with the table is ...

  y = 600/x³

The y-value can be found using the equation ...

  y = 600/x³

  y = 600/5³ = 600/125 = 24/5

  y = 4.8

Solving the proportion for x gives ...

  x³ = k/y

  x = ∛(k/y) = ∛(600/75) = ∛8

  x = 2

Now, we can fill the table as in the attachment.

Angles in a triangle add up to 180.

The length of the segment BC which is having midpoint DE is 6cm.

Given that GH is the mid-segment of triangle DEF and DE is the mid-segment of triangle ABC. From this relation, we can obtain the length of the segment BC easily.

The relation between the base and mid-segment of the triangle is,

base = 2 x mid-segment

So, in triangle DEF the length of the base DE = 2 x GH

                                                                      DE = 2 x 1.5 cm = 3 cm.

Similarly, in triangle ABC the length of the base BC = 2 x DE

                                                                                BC = 2 x 3 cm = 6 cm.

From the above analysis, we can conclude that the length of the segment BC is 6cm.

Answer:

Let x be the length of one side of the square. Then, the perimeter of the square is 4x.

Each rectangle has two sides that are equal in length to the side of the square, and two sides that are equal in length to some other value y. Therefore, the perimeter of each rectangle can be expressed as:

2x + 2y = 20

Simplifying this equation, we get:

x + y = 10

We can use this relationship to solve for y in terms of x:

y = 10 - x

The area of each rectangle is given by:

Area = x*y

Substituting y = 10 - x, we get:

Area = x*(10-x)

Area = 10x - x²

To find the area of each rectangle, we need to solve for x. We know that the area of the square is 44 cm², so:

x² = 44

x ≈ 6.63 cm

Now we can find the area of each rectangle:

Area = 10x - x²

Area = 10(6.63) - (6.63)²

Area ≈ 38.85 cm²

Therefore, each rectangle has an area of approximately 38.85 cm².

The difference in density, in pounds per cubic foot, between the box A and box B to the nearest whole number is 3. So, correct answer is option b.

The density of the body is the mass per unit volume and to find the difference in density we have to find density of each box.

Density of box A = Mass of box A / Volume of box A

= 24.6 pounds / 4 cubic feet

= 6.15 pounds per cubic foot

Density of box B = Mass of box B / Volume of box B

= 37.4 pounds / 4 cubic feet

The type II error occurs in the example.

According to the given conditions, the null thesis( H0) is that the food is safe, while the alternative thesis( Ha) is that the food isn't safe. The food inspectors are trying to test this thesis by examining samples of the food product and looking for any signs that it may be unsafe.

A type II error occurs when the examination process fails to descry an unsafe condition in the food product, indeed though it actually exists. In other words, the sample data suggests that the food is safe, but it's not. This means that the null thesis( H0) is accepted when it should have been rejected in favor of the alternative thesis( Ha).

In practical terms, a type II error in this environment could be dangerous, as it could affect unsafe food being distributed to consumers, potentially leading to illness or indeed death. thus, it's important for food inspectors to minimize the threat of type II crimes by using applicable slice styles and testing procedures to ensure the safety of the food products they check.

There are 130 positive integers less than 1000 that are divisible by 7 but not by 11.

The rule used to find the number of positive integers less than 1000 that are divisible by 7 but not by 11 is the inclusion-exclusion principle. This principle states that if we want to find the number of elements that belong to at least one of two sets, we can add the sizes of the sets together and then subtract the size of the intersection of the sets. In this case, we first find the number of positive integers less than 1000 that are divisible by 7 (which is 142), then the number that are divisible by 11 (which is 90), and finally the number that are divisible by both (which is 12). Using the inclusion-exclusion principle, we can find the number of positive integers less than 1000 that are divisible by 7 but not by 11 by subtracting the number that are divisible by both from the number that are divisible by 7: 142 - 12 = 130. Therefore, there are 130 positive integers less than 1000 that are divisible by 7 but not by 11.
To find the number of positive integers less than 1000 that are divisible by 7 but not by 11, you can use the Inclusion-Exclusion Principle.

First, find the number of integers divisible by 7: there are 999/7 = 142.71, so 142 integers are divisible by 7.

Next, find the number of integers divisible by both 7 and 11 (i.e., divisible by their LCM, which is 77): there are 999/77 = 12.97, so 12 integers are divisible by 77.

Now, apply the Inclusion-Exclusion Principle: Subtract the number of integers divisible by both 7 and 11 from the number of integers divisible by 7: 142 - 12 = 130.

The requried domain restriction for both functions is x ≥ 0.

a. f(x) = x² {x ≥ 0}

To make f(x) one-to-one, we need to restrict the domain so that each output (y-value) of the function fits only one input (x-value). The domain is x ≥ 0, which means that the function starts from the point (0,0) and goes up as x increases. Therefore, the domain restriction for f(x) to be one-to-one is x ≥ 0.

Answer:

the range describes the distance from the minimum to the maximum value of the entire data set.

Answer:

the dilation in g(x) as it relates to the parent function f(x) is a vertical dilation by a factor of 15000.

Step-by-step explanation:

The function g(x) is a dilation of the parent function f(x) = 0.98^x.

Specifically, g(x) = 15000(0.98)^x is a vertical dilation of f(x) = 0.98^x by a factor of 15000.

This means that the graph of g(x) is the same shape as the graph of f(x), but it is vertically stretched by a factor of 15000.

In other words, the values of g(x) are 15000 times greater than the values of f(x) for any given value of x.

For example, when x = 1, f(1) = 0.98 and g(1) = 15000(0.98) = 14700. This means that the number of visitors to the water park in the second month (x = 1) is 15000 times greater than the number of visitors in the first month.

Overall, the dilation in g(x) as it relates to the parent function f(x) is a vertical dilation by a factor of 15000.

determine which candidates are actually zeros, and then factor the polynomial. To do this

Theorem.

2. Divide: Use Synthetic division to evaluate the polynomial at each of the

candidates for rational zeros that you found in Step 1. When the

remainder is 0, note the quotient you have obtained.

3. Repeat: Repeat Steps 1 and 2 for the quotient. Stop when you reach a

quotient that is quadratic or factors easily, and use the quadratic formula

or factor to find the remaining zeros.

Example 2 (Continued):

theorem that is helpful in eliminating candidates is Descartes’ Rule of Signs.

of variations in sign in P(x) or is less than that by an even whole

number.

2. The number of negative real zeros of P(x) is either equal to the number

Complementary angles sum to 90°.

We can build an equation to find any two complementary angles.

x + y = 90

Either x or y is given. Notice how they're interchangeable which means it doesn't make any difference what value you plug in for x or y.

We can plug in 37 for x or y, but I always plug it in for x.

37 + y = 90
