Triangle AXC is congruent to triangle AYB by the SAS Congruence Criteria.

In geometry, two triangles are said to be congruent if they have the same shape and size. More specifically, two triangles are congruent if all three sides and all three angles of one triangle are equal to the corresponding sides and angles of the other triangle. When two triangles are congruent, they can be superimposed on top of each other, and all corresponding parts of the triangles will match exactly.

There are several ways to prove that two triangles are congruent, including using the side-angle-side (SAS) theorem, the angle-side-angle (ASA) theorem, the side-side-side (SSS) theorem, and the hypotenuse-leg (HL) theorem.

Given that |AB|=|CD| and triangle ABC is isosceles.

We need to prove that triangle AXC = triangle AYB.

To do so, we will use the Side-Angle-Side (SAS) Congruence Criteria.

AC = BC (Given)

∠ACX = ∠BCY (Vertical Angles)

∠CAX = ∠CBY (Base Angles of Isosceles Triangle)

Therefore, triangle AXC is congruent to triangle AYB by the SAS Congruence Criteria.

Hence, proved.

Answer:4. (a) BMN = 75°(b) AMP = 105°Explanation:Given that ABC is an isosceles triangle with base BC, and ABC = 75°. Also, BC = MB = PM and MN || BC.(a) To find BMN, we can use the fact that MN || BC. This means that ∠BMN = ∠ABC = 75°. Therefore, BMN = 75°.(b) To find AMP, we can use the fact that BC = MB = PM. This means that triangle BMP is an isosceles triangle with base MP. Since BMN = 75°, we can find ∠BMP by using the fact that the sum of the angles in a triangle is 180°:∠BMP = (180° - 75°)/2 = 52.5°Now, we can find AMP by using the fact that the sum of the angles in a triangle is 180°:AMP = 180° - 75° - 52.5° = 52.5°Therefore, AMP = 105°.

(a) The angle BMN is 30°.

(b) The angle AMP is 15°.

The total angle of a triangle is 180°.

We have an isosceles triangle ABC with base BC and ∠ABC is 75°. We construct point M on AC and N, P on AB. It makes BC = MB = PM and MN || BC.

Since ABC is an isosceles triangle, ∠ACB is also 75°. See the picture attached!

Since BC = MB, the triangle MBC is isosceles with base MC. So, BMC is 75°.

The angles of triangle MBC will sum up to 180°. So,

∠MBC = 180 - (75 + 75) = 30°

The angle BMN and MBC is alternate interior angles, so

∠BMN = ∠MBC = 30°

Now, we have ∠NBM = 75 - 30 = 45°. Since MB = PM, it makes BMP an isosceles triangle. The angle BPM will be the same with PBM. It is 45°.

The angle PMN will be

= 180 - (45 + 45 + 30)

= 60°

The angle CMB, BMN, NMP, and AMP are supplementary. So, the angle AMP is

= 180 - (75 + 30 + 60)

= 15°

Answer: Let's use the variables x and y to represent the number of small boxes and large boxes shipped, respectively.

The system of equations that could be used to determine the number of each type of box is:

x + y = 21 (equation 1)

7x + 14y = 252 (equation 2)

In equation 1, the left side represents the total number of boxes shipped, which is the sum of the number of small boxes (x) and the number of large boxes (y). The right side of the equation represents the total number of boxes shipped, which is given as 21.

In equation 2, the left side represents the total volume of paper shipped, which is the sum of the volume of all the small boxes (7 cubic feet per box) and the volume of all the large boxes (14 cubic feet per box), multiplied by the number of boxes shipped. The right side of the equation represents the total volume of paper shipped, which is given as 252 cubic feet.

These two equations can be used to solve for x and y, which represent the number of small boxes and large boxes shipped, respectively.

Step-by-step explanation:

Answer: the number that goes beneath the radical symbol is 17

The solution to the system of equations using elimination is:

x = 1058/1890

y = 26/90

To solve this system of equations using elimination, we will add the two equations together and rearrange the terms.

2y = x - 5

2y = x + 5

Add the equations together:

2y + 2y = x - 5 + x + 5

4y = 2x + 0

Rearrange the terms:

4y - 2x = 0

We will now use this equation and the equation x + 2y = 13 to solve for x and y.

Substitute 4y - 2x = 0 into x + 2y = 13:

x + 2(4y - 2x) = 13

x + 8y - 4x = 13

Rearrange the terms:

5x + 8y = 13

Substitute 4y - 2x = 0 into 5x + 8y = 13:

5x + 8(4y - 2x) = 13

5x + 32y - 16x = 13

Rearrange the terms:

21x + 32y = 13

Divide by 21:

x + (32/21)y = 13/21

Rearrange the terms:

x = 13/21 - (32/21)y

Substitute x = 13/21 - (32/21)y into 4y - 2x = 0:

4y - 2(13/21 - (32/21)y) = 0

4y - (26/21) + (64/21)y = 0

Rearrange the terms:

(90/21)y = 26/21

y = (26/21) / (90/21)

y = 26/90

Substitute y = 26/90 into x = 13/21 - (32/21)y:

x = 13/21 - (32/21)(26/90)

x = 13/21 - (832/1890)

x = 1058/1890

The solution to the system of equations is:

A confidence interval of proportions has the bounds given by the rule presented as follows:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which the variables used to calculated these bounds are listed as follows:

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

The margin of error is modeled as follows:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

We have no estimate of the proportion, hence it is used as follows:

[tex]\pi = 0.5[/tex]

The margin of error is of M = 0.01, hence the sample size is obtained as follows:

[tex]0.01 = 1.96\sqrt{\frac{0.5(0.5)}{n}}[/tex]

[tex]0.01\sqrt{n} = 1.96 \times 0.5[/tex]

The number of degrees for each part of the museum visitors graph would be Age 18 and under: 108 degrees, Age 19 – 44: 180 degrees, Age 45 – 64: 54 degrees, and Age 65 and over: 18 degrees.

To find the number of degrees for each part of the museum visitors graph, we need to know the total number of visitors for that month. Let's assume that the total number of visitors for the month is 10,000.

Age 18 and under:

Let's assume that the number of visitors aged 18 and under is 3,000. To find the number of degrees for this section of the graph, we need to use the formula: (Number of visitors in the age group / Total number of visitors) x 360 degrees. So, (3000/10000) x 360 = 108 degrees.

Age 19 – 44:

Let's assume that the number of visitors aged 19-44 is 5,000. Using the same formula as above, we get (5000/10000) x 360 = 180 degrees.

Age 45 – 64:

Let's assume that the number of visitors aged 45-64 is 1,500. Using the same formula as above, we get (1500/10000) x 360 = 54 degrees.

Age 65 and over:

Let's assume that the number of visitors aged 65 and over is 500. Using the same formula as above, we get (500/10000) x 360 = 18 degrees.

(a)  The future value of the investment if interest is compounded semiannually is $24,840.28.

(b) The future value of the investment if interest is compounded quarterly is $25,025.68.

(c) The future value of the investment is $185.40 greater when the interest is compounded quarterly.

The future value of an investment can be calculated using the formula FV = P(1 + r/n)^(nt), where FV is the future value, P is the principal amount deposited, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years the investment is held.

If the interest is compounded semiannually, then n = 2. Plugging in the given values, we get:

FV = 18000(1 + 0.04/2)^(2*9)

FV = 18000(1.02)^18

FV = $24,840.28

So the future value of the investment if interest is compounded semiannually is $24,840.28.

If the interest is compounded quarterly, then n = 4. Plugging in the given values, we get:

FV = 18000(1 + 0.04/4)^(4*9)

FV = 18000(1.01)^36

FV = $25,025.68

So the future value of the investment if interest is compounded quarterly is $25,025.68.

To find out how much greater the future value of the investment is when the interest is compounded quarterly, we can subtract the future value when interest is compounded semiannually from the future value when interest is compounded quarterly:

$25,025.68 - $24,840.28 = $185.40

So the future value of the investment is $185.40 greater when the interest is compounded quarterly.
