In the problem, we are already given 2 pairs of sides that are congruent: AB and ED, and AD and BE.

Using the reflexive property of congruence, we also know that segment BD is congruent to itself.

We have therefore used three pairs of sides that are congruent to prove that △ABD ≅ △EDB.

This means that we used the SSS Postulate to prove the congruence of the two triangles.

Answer:

Domain: [-8, 2]

Range: [-4, 0]

Function: Yes

Step-by-step explanation:

The domain is the set of x-values and the range is the set of y-values.

A relation is a function if each x value corresponds to only one y-value.

The constant of proportionality of total weight to number of eggs having the weight of 8 eggs as  496 grams is 62.

The  weight of 8 eggs is given as 496 grams

The equation can be written as :

w=n

where n= number of the eggs

we= weight of the eggs

then the equation can be written as

w∝n

Then we can introduce the proportionality constant sign as ;

then w=kn

where k is the proportionality constant

then we can substitute the given figures as ;

496=k *8

then k=496/8 = 62.

Therefore third option is correct.

Given the model for the height of a ball:

To hit the ground, the height must be h(t) = 0. Then:

We use the general solution for a quadratic equation:

From the problem, we identify:

Using the formula:

We only take the positive value (because the time is always positive!). Then, the answer is:

The equations of the line are:

y – 2 = 2(x – 5)

y + 16 = 2(x + 4)

y = 2x – 8

The equation of a line, in point-slope form, that passes through two points can be expressed as y - b = m(x - a).

To find the equation, first, we will need to find the slope of the line. Next, we will use a point and the slope to write the equation by simply substitute their values in y - b = m(x - a), where the slope is m and a point is (a, b).

Given the points:

Find the slope of the line (m):

Slope of the line (m) = change in y / change in x = (-16 - 2)/(-4 - 5)

Slope of the line (m) = -18/-9

Slope of the line (m) = 2

Substitute m = 2 and (a, b) = (5, 2) into y - b = m(x - a):

y - 2 = 2(x - 5)

Or, substitute m = 2 and (a, b) = (-4, -16) into y - b = m(x - a):

y + 16 = 2(x + 4)

Any of the above equations can be rewritten in slope-intercept form as:

y = 2x - 8.

The product of the given expression will be -49 + 13√7.

Product of two entities may be used to increase the amount of those entities. A radical expression may be defined as an expression which along with numbers and variables contain square root symbol. Instead of square root there can be cube root, fourth root or of root with any power. For example, 1 + √4, 1 + ∛4 etc. We have the expression (7 - √7) (-6 + √7). The product of this expression will be

Product = (7 - √7) (-6 + √7)

Product = -42 + 7√7 + 6√7 - 7

The frequency for the given distribution of the class interval 1.00 - 1.09 is 3, which are 1.07, 1.05 and 1.07.

The frequency of a repeating event is its number of instances per unit of time. In some cases, it is also referred to as temporal frequency or ordinary frequency to emphasise differences with spatial and angular frequencies, respectively. One (event) per second is equal to one hertz (Hz), which is how frequency is expressed.

The period is the reciprocal of the frequency because it is the length of time for one cycle in a repeating event. For instance, the period, T—the space between beats—of a heart beating at a frequency of 120 beats per minute (2 hertz), is equal to 0.5 seconds (60 seconds divided by 120 beats).

Step-by-step explanation:

The sequence converges because |r| = 0.125, which is less than one. The correct answer would be option (C).

The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.

The nth term of a geometric progression is expressed as

Tₙ = arⁿ⁻¹

Where a is the first term, r is the common ratio

We have been given that geometric sequence as:

320, -40, 5, -0.625,...

To determine whether the geometric sequence converges or diverges

We have to find the common ratio of the given sequence.

|r | = | -40/320 |

|r | = 0.125 < 1

Since the common ratio of the sequence is less than 1,

Therefore, the given sequence converges.

Hence, the correct answer would be an option (C).

The laboratory technician has to combine 11 L  acid solution to get the desired concentration .

The volume of solute that has been dissolved in a specific volume of solvent or solution is known as the concentration of a solution. A solution with a significant concentration of dissolved solute is one that is concentrated. When there is just a minimal amount of dissolved solute in a solution, it is said to be diluted. The amount of a solute, or dissolvable substance, combined with the solvent, or other substance, determines the concentration of a solution in chemistry. C = m/V, where m is the mass of the solute dissolved and V is the total volume of the solution, is the accepted formula. Among the quantitative units of concentration are molarity, molality, mass percentage, parts per thousand, parts per million, and parts per billion.

The33 L batch is 40% acid, so 33 x 0.4 = 13.2 L of pure acid in the batch.

Let P = the number of liters of pure acid required, D = the number of liters of the 10 % solution.

Then P + 0.10 x D = 13.2.  

Also, P + D = 33

This equation can be solved simultaneously by substitution.

P = 33 - D

33 - D + 0.10 x D = 16.8

-D (1 - 0.10) = 13.2 - 33

-D =  -19.2/ 0.9

D = -22

P = 33 - 22

= 11 L

Answer:

0.825 inches per hour

Step-by-step explanation:

Invasive weed species can grow quickly. One variety grows up to 1.65 ft per day. How fast in inches per minute can this weed grow?

FACTS:

the weed grows up to 1.65 feet per day

there are 12 inches in 1 foot

there are 24 hours in 1 day

First, lets figure how many inches the weed can grow in one day:

= daily growth in feet per day * inches in 1 foot

= 1.65 feet * 12 inches

= 19.8 inches a day

If the weed can grown 19.8 inches a day, and there are 24 hours in a day:

= growth in inches per day/24 hours in 1 day

=19.8/24

= 0.825 inches per hour

x² +3x+9 and x² + 9 are prime polynomials.

A whole number higher than 1 whose only elements are 1 and itself is referred to as a prime number. A whole number that may be split evenly into another number is referred to as a factor. 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29 are the first few prime numbers. Composite numbers are those that have more than two components. A prime number is one that can only be divided without leaving a residue by itself and one.

Given Data

x² +9

x² + 9 cannot be divided into factors of rational numbers. It is a prime polynomial as a result.

x²+3x+9

It is impossible to factorize x² + 3x + 9 using rational values. It is a prime polynomial as a result.

x²-9

Factoring x² - 9 results in (x - 3)(x + 3). It is not a prime polynomial, therefore.

This is a linear relation. For linear relations, we have the general form:

Where 'a' is the slope and 'b' is the intercept.

In this problem, we have that the intercept b is 200, because that's the point where the line crosses the y-axis. For now we have something like:

(here y is C and x is m)

To find the slope we have to use the intercept point (0, 200) and another point on the line. We can see that one of those points is (200, 500).

For a line with points (x1, y1) and (x2, y2), the slope is find like:
