Which are true about the regular hexagon? Check all that apply.

Answer:

equal angles and vertical angles

Step-by-step explanation:

we know that

Vertical Angles are the angles opposite each other when two lines cross. They are always equal

In this problem

∠14=∠16 -----> by vertical angles

therefore

The answer is

equal angles and vertical angles

Answer:

Vertical angles, equal angles

Step-by-step explanation:

when a transversal passes through two lines, then,

Angles formed in the same side and inside the two lines are same side interior angles.

Angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.

Angles formed on opposite sides of the transversal and outside the two lines are alternate exterior angles.

Angles with the same relative position at each intersection are corresponding angles,

While, when two lines intersect each other then the opposite angles formed called vertical angles,

supplementary angles : When the sum of two angles are 180°,

Right angles : angle that has the measurement of 90°,

Equal angles : angles with the same measurement.

Now, vertical angles are always equal angles,

Also, when two parallel lines are cut by the same transversal then the pair of alternate interior angles, alternate exterior angles, corresponding angles are always equal.

Hence, by above definitions it is clear that,

∠16 and ∠14 are vertical and equal angles.

For every input, there is one output.

Why table 1 is not a function:

The input 5 has two outputs, 3 and 2

Why table 3 is not a function:

The input 1 has two outputs, 2 and 3

Why table 4 is not a function:

The input 4 has three outputs, 2, 3, and 4

Hope this helps!

Answer:The initial values of the two functions are different, and the rates of change of the two functions are the same.

Step-by-step explanation:

The values will start out different. When you apply the rate of change, because they have the same rate of change, you don't risk them coming out with the same value if the values ended up being just right, they will always remain different.

The differences in the output values for linear function A and function B are a result of varying y-intercepts and slopes in each function. When plotted on a graph, these differences become apparent.

The output values for linear function A and function B will differ because of variations in their respective initial values (or y-intercepts) and their rates of change (or slopes). When you plot these output values against the shared input values as a graph of y as a function of x, these differences can be seen visually. For instance, consider the linear equation y = mx + b, where m represents the slope of the line and b is the y-intercept. If function A and B have different y-intercepts or slopes, the output values will differ for the same set of input values.

Answer:

±(√35 i)

Step-by-step explanation:

[tex]\pm\sqrt{-35}[/tex]

We need to solve the above equation using the imaginary unit i.

We know i= √-1

Solving

±√-35 =±( √-1 √35)

         = ±(√35 i)Since 35 = 5*7 or 35*1 it cannot be further simplified

So our answer is ±(√35 i).

The sum of the angles of any quadrilateral is 360 degrees. This means that you can make a formula like the one bellow and solve for x:

Answer:

Option. A

Step-by-step explanation:

Covert Ounces to Pounds, or vice versa, I went with pounds.

1323 ounces = 82 pounds.

find the pound to dollar rate

A; 82 ÷ 410.13 = about 5

B; 8 ÷ 78.08 = 9.76

The better buy is A. 1,323 ounces of topsoil for $410.13.

To determine which is the better buy, we need to calculate the price per ounce for both options and then compare them.

First, let's calculate the price per ounce for option A:

1,323 ounces of topsoil for $410.13.

Price per ounce for A = $410.13 / 1,323 ounces.

Now, let's calculate the price per ounce for option B:

Since 1 pound is equal to 16 ounces, 8 pounds of topsoil is equal to

8 × 16 = 128 ounces.

8 pounds of topsoil for $78.08.

Price per ounce for B = $78.08 / 128 ounces.

Next, we compare the price per ounce for both options:

Price per ounce for A = $410.13 / 1,323 ounces  $0.310 / ounce.

Price per ounce for B = $78.08 / 128 ounces  $0.609 / ounce.

Since the price per ounce for option A ($0.310) is less than the price per ounce for option B ($0.609), option A is the better buy. The customer gets more topsoil for their money with option A.

Answer: OPTION C.

Step-by-step explanation:

Given a function f(x), the range of the inverse of f(x) will be the domain of the function f(x) and the range of the domain of f(x) will be the range of the inverse function.

For example, if the point (2,1) belongs to f(x), then the point (1,2) belongs to the inverse of f(x).

Observe that in the graph of the function f(x) the point (-3,1) belongs to the function, then the point (1,-3) must belong to the inverse function.

Therefore, you need to search the option that shown the graph wich contains the point (1,-3).

Observe that the Domain f(x) is (-∞,0) then the range of the inverse function must be (-∞,0).

This is the graph of the option C.

what we do is, we simply draw the graph for its EQUALITY counterpart, namely  [tex]\bf y=-\cfrac{1}{6}x+1[/tex].

then we check the regions on both sides of the graph, in this case we can check say the point (0,0) for simplicity, and

[tex]\bf y>-\cfrac{1}{6}x+1\qquad (0,0)~~ \begin{cases} x=0\\ y=0 \end{cases}\implies 0>-\cfrac{1}{6}(0)+1\implies 0>1[/tex]

now, is 0 > 1? is 0 really greater than 1? nope, is smaller, thus the area where the point (0, 0) is at is the false region, so that's the area we do NOT shade, thus the other region must be the true region and that's the one we shade.

the ">" sign means, that "y" is greater than, NOT equals to but greater, thus the values at the borderline are not included, and thus is a dashed line.

Answer:

D. 20%

Step-by-step explanation:

percent change = (new number - old number)/(old number) * 100%

The new number is the increased price, $42, and the old number is the original price, $35.

percent change = ($42 - $35)/($35) * 100%

percent change = ($7)/($35 min) * 100%

percent change = 0.20 * 100%

percent change = 20%

Since the percent change is a positive number, it is a percent increase.

The percent increase was 20%.

Answer: D. 20%

Answer:

160

Step-by-step explanation:

e.g. 5×8 --> 10×16 =160

4×10 --> 8×20 =160

2×20 --> 4×40 =160

160

When you double both the length and width, you are multiplying by 2 twice. Whatever you do to one side of an equation, you have to repeat on the other.

l * w = 40; This is the original equation.

2l * 2w = 40 * 2 * 2; This is when you double the length and the width.

The 2 * 2 on the end can be simplified.

2l * 2w = 40 * 4

Now, simplify 40 * 4.

2l * 2w = 160

So, when you double both the length and the width, you multiply the area by 4, making the area 160.

Answer:

A. Obtuse

F. Scalene

Step-by-step explanation:

There are two ways to classify a triangle:

by angles:

Obtuse - has one angle that is greater than 90°

Right - has one angle that is 90°

Acute - has all angles less than 90°

and by side lengths:

Equilateral - all sides are equal

Isosceles - two sides are equal

Scalene - no sides are equal

In this triangle, there is an obtuse angle (A. Obtuse).

∡ = 132°, which is greater than 90°.

There are no equal sides (F. Scalene).

The answer is:

Anna will need 27 posts.

To calculate how many post does she need to place at the corners and every 2 feet around, we need to calculate the perimeter of the garden plot.

So, we can calculate the perimeter of the garden plot (rectangle) using the following formula:

[tex]Perimeter=2height+2width[/tex]

We know that:

[tex]height=9ft\\width=18ft[/tex]

Then, calculating the perimeter of the garden plot, we have:

[tex]Perimeter=2height+2width[/tex]

[tex]Perimeter=2*9ft+2*18ft=18ft+36ft=54ft[/tex]

Now, calculating how many post she will need, we have:

[tex]No.Post=\frac{Perimeter}{DistanceBetweenPost}\\\\\frac{54feet}{2feet}=27posts[/tex]

Hence, we have that Anna will need 27 posts.

Final answer:

To construct the perpendicular bisector of AB, connect the intersections of the circles drawn from A and B with the same radius using a straightedge.

Explanation:

The student has asked what the best next step is in the construction of the perpendicular bisector of a line segment AB. The correct answer is C, which states that you should use a straightedge to draw a line segment that connects the intersections of the circles. This will create the perpendicular bisector of AB. The process involves drawing two circles with the same radius from points A and B, such that each circle goes through the other point, and then connecting the two points where the circles intersect with a straight line. This line will be the perpendicular bisector because it will be perpendicular to AB and divide it into two equal parts, hence bisecting AB.

Answer:

Step-by-step explanation:

Sigma notation is:

n

∑ ak

k=1

The n on top is the number of terms.  ak is the expression for the kth term.

Let's look at the first one.  The series is:

-2+4+-8+...+64+-128

There's two things to notice.  One, the sign changes back and forth between + and -.  Two, the magnitude doubles with each next term.  Therefore:

ak = (-2)ᵏ

Next we need to find the number of terms.  -128 is the last term, so:

128 = 2ⁿ

n = 7

So the answer is:

7

∑ (-2)^k

k=1

Now the second one.  Notice the numerators are all 1 and the denominators are all perfect squares.  Therefore:

ak = (1/k)²

The last term is 1/100, so n = 10.

So the answer is:

10

∑ (1/k)²

k=1

Now the last one.  Notice that each term is 5 plus the previous term.  This is an arithmetic series.  So we can say:

ak = 4 + 5(k-1)

ak = 4 + 5k - 5

ak = 5k - 1

The last term is 49, so:

49 = 5n - 1

n = 10

So the answer is:

10

∑ (5n-1)

k=1
