The measure of angle ∠ZTB of triangle SRT is 31°.

A triangle is a flat geometric figure that has three sides and three angles. The sum of the interior angles of a triangle is equal to 180°. The exterior angles sum up to 360°.

For the given situation,

Let S R T be a triangle, and point Z is the in center of triangle S R T.

Lines are drawn from point Z to the sides of the triangle to form right angles and line segments Z A, Z B, and Z C as shown in the below figure.

Here, ∠ AZR = 35°, ∠ZRC = 35°, ∠ BSZ = 24°, ∠ZSA = 24°, ∠ZTB = ?

The in center of a triangle is the intersection point of all the three interior angle bisectors of the triangle. It can be defined as the point where the internal angle bisectors of the triangle cross.

According to the angle bisector theorem,

⇒ \(\angle ZRC = \angle ARZ\)

⇒ \(\angle ARZ = 35\degree\)

Let the unknown angle, ∠ZTB be x. Then ∠BTC = 2x

The sum of the interior angles of a triangle is equal to 180°,

So, \(24+24+35+35+2x=180\)

⇒ \(118+2x=180\)

⇒ \(2x=180-118\)

⇒ \(x=\frac{62}{2}\)

⇒ \(x=31\)

Hence we can conclude that the measure of angle ∠ZTB of triangle SRT is 31°.

The compound interest is $348,966.97 and the future value is $464,966.97.

percentage, a relative value indicating hundredth parts of any quantity.

We can use the formula for compound interest to calculate the future value of the investment:

\(FV=P(a1+r/n)^{nt}\)

where:

P = the principal amount (the initial investment)$116,000

r = the annual interest rate (as a decimal)=0.0429

n = the number of times the interest is compounded per year=52

t = the number of years=34

Plugging in these values, we get:

FV = $116,000(1 + 0.0429/52)¹⁷⁶⁸

FV = $464,966.97

So the future value of the investment after 34 years is $464,966.97.

Compound interest = $464,966.97 - $116,000 = $348,966.97

Applying the chord theorem, since chords RS and TU are equal, then the measure of arc RS is: 106°.

The chord theorem states that if two chords in a circle are equal in length, then their corresponding minor arcs will also be equal in measure.

Since chords RS = TU, therefore:

m(RS) = m(TU)

Substitute

8x - 14 = 7x + 1

8x - 7x = 14 + 1

x = 15

m(RS) = 8x - 14

Plug in the value of x

m(RS) = 8(15) - 14

m(RS) = 106°

Angle 4 is an exterior angle which is equal to the sum of the two opposite inside angles.

The two opposite inside angles are given as 51 and 51

Angle 3 = 51 + 51 = 102 degrees.

Answer:

\( \displaystyle \angle4 = {108}^{ \circ} \)

Step-by-step explanation:

the sum of the interior angles of a triangle is 180°

thus our equation is

\( \displaystyle {51}^{ \circ} + {51}^{ \circ} + \angle2 = {180}^{ \circ} \)

simplify addition:

\( \displaystyle {102}^{ \circ} + \angle2 = {180}^{ \circ} \)

cancel 102° from both sides:

\( \displaystyle \angle2 = {72}^{ \circ} \cdots \text{I}\)

By straight line theorem we acquire:

\( \displaystyle \angle4 + \angle2 = {180}^{ \circ} \)

substitute:

\( \displaystyle \angle4 + {72}^{ \circ} = {180}^{ \circ} \)

cancel 72° from both sides:

\( \displaystyle \angle4 = {108}^{ \circ} \)

hence, the measure of \(\angle 4\) is 108°

The intermediate step in completing the square is\($x^2 + 2ax + (a^2) = b - a^2 + (a^2)$\)

To complete the square for the equation \($(x+a)^2=b$\), we can follow these steps:

1. Expand the left side of the equation: \($(x+a)^2 = (x+a)(x+a) = x^2 + 2ax + a^2$\).

2. Rewrite the equation by isolating the squared term and the linear term: \($x^2 + 2ax = b - a^2$\).

3. To complete the square, take half of the coefficient of the linear term, square it, and add it to both sides of the equation:

\($x^2 + 2ax + (a^2) = b - a^2 + (a^2)$\).

4. Simplify the right side of the equation: \($x^2 + 2ax + (a^2) = b$\).

This step can be represented as: \(\[x^2 + 2ax + (a^2) = b - a^2 + (a^2)\]\)

This intermediate step helps us rewrite the equation in a form that allows us to factor it into a perfect square.

look x can not be with 2 Y's so if it is 2 x's and 1 Y it is not a function if it is 1 x and 1 y it is a function.

Answer:

B. 1

Step-by-step explanation:

Let's use the formula for finding the mean of a set of data:

mean = (sum of all data values) / (number of data values)

We know that the mean is 2.2, and we have all the other data values except for one. Let's call the missing value "x". The total number of data values is 10 (since there are 10 scores listed in the frequency table). So we can set up an equation:

2.2 = (sum of all 10 data values, including x) / 10

Multiplying both sides by 10, we get:

22 = sum of all 10 data values, including x

We can then subtract the sum of the known data values from both sides to find the missing value:

22 - (01 + 12 + 23 + 31 + 42 + 51) = x

22 - (0 + 2 + 6 + 3 + 8 + 5) = x

x = 22 - 24 = -2

However, a quiz score cannot be negative, so we made a mistake somewhere. Checking the frequency table, we see that there are no scores of 0 or 1, so the missing score must be 0 or 1. Let's try both possibilities:

If the missing score is 0:

2.2 = (01 + 12 + 23 + 31 + 42 + 51 + 0*1) / 10

2.2 = 18 / 10

2.2 = 1.8

This is not true, so the missing score cannot be 0.

If the missing score is 1:

2.2 = (01 + 12 + 23 + 31 + 42 + 51 + 1*?) / 10

2.2 = (18 + ?) / 10

22 = 18 + ?

? = 4

So the missing score is 1, and the answer is B.

Answer:

Answer is B

Total scores/total frequency =mean

Then you can state that angle DEF is congruent to angle GHJ.

The postulate or theorem that allows you to state that angle DEF is congruent to angle GHJ is the Angle-Angle (AA) Postulate.

This postulate states that if two angles of one triangle are congruent to two angles of another triangle, then the third pair of angles must also be congruent.

In this case, if you have two triangles, one with angles DEF and the other with angles GHJ, and

you know that angle D is congruent to angle G and angle E is congruent to angle H, then by the AA Postulate, you can conclude that angle F is congruent to angle J.

Answer:

If b=5:7, find the value of B in terms of c

The Expression x^2 - 6x + 9 when x = 2 + i   is -2i

To evaluate the expression x^2 - 6x + 9 when x = 2 + i, we substitute the value of x into the expression:

(2 + i)^2 - 6(2 + i) + 9

Simplifying the first term, we get:

(2 + i)^2 = 2^2 + 2(2)(i) + i^2 = 4 + 4i + i^2

Since i^2 = -1, we can substitute that in and simplify further:

(2 + i)^2 = 4 + 4i - 1 = 3 + 4i

Now we substitute this into the original expression:

(2 + i)^2 - 6(2 + i) + 9 = (3 + 4i) - 6(2 + i) + 9

Simplifying further, we get:

= 3 + 4i - 12 - 6i + 9

= 0 - 2i

= -2i

Therefore, the value of x^2 - 6x + 9 when x = 2 + i is -2i.

The angle between u and v is approximately 26.6 degrees.

To find the angle between two vectors, u and v, we can use the dot product formula:

u · v = ||u|| ||v|| cosθ

where u · v represents the dot product of u and v, ||u|| and ||v|| represent the magnitudes of u and v respectively, and θ represents the angle between the vectors.

Given that u = (8, -2) and v = (5, -5), we can calculate the dot product as follows:

u · v = (8 * 5) + (-2 * -5) = 40 + 10 = 50

Next, we find the magnitudes of u and v:

||u|| = √(8^2 + (-2)^2) = √(64 + 4) = √68 ≈ 8.246

||v|| = √(5^2 + (-5)^2) = √(25 + 25) = √50 ≈ 7.071

Substituting these values into the dot product formula:

50 = 8.246 * 7.071 * cosθ

Simplifying, we have:

cosθ = 50 / (8.246 * 7.071) ≈ 0.899

Taking the inverse cosine (arccos) of 0.899, we find:

θ ≈ 26.6 degrees

Therefore,To find the angle between two vectors, u and v, we can use the dot product formula:

u · v = ||u|| ||v|| cosθ

where u · v represents the dot product of u and v, ||u|| and ||v|| represent the magnitudes of u and v respectively, and θ represents the angle between the vectors.

Given that u = (8, -2) and v = (5, -5), we can calculate the dot product as follows:

u · v = (8 * 5) + (-2 * -5) = 40 + 10 = 50

Next, we find the magnitudes of u and v:

||u|| = √(8^2 + (-2)^2) = √(64 + 4) = √68 ≈ 8.246

||v|| = √(5^2 + (-5)^2) = √(25 + 25) = √50 ≈ 7.071

Substituting these values into the dot product formula:

50 = 8.246 * 7.071 * cosθ

Simplifying, we have:

cosθ = 50 / (8.246 * 7.071) ≈ 0.899

Due to the difference in their price elasticity of demand, if a per-unit excise tax of the same amount is imposed on goods X and Y, the quantity demanded for good Y will decline more than the quantity demanded for good X.

1. Consider Good X with Price Elasticity of Demand (-0.5):

The demand for good X is inelastic if the price elasticity of demand is less than zero (-0.5).

This suggests that consumers are not particularly responsive to price changes and that changes in price do not considerably affect the quantity demanded.

Excise tax effects on good X:

When good X is subject to excise tax, its price will rise. The quantity demanded won't drastically decrease because the demand is inelastic.

2. Good Y with a (-2) demand price elasticity

Demand for good Y is elastic if price elasticity of demand is -2. This shows that consumers react quickly to price fluctuations and that the amount requested fluctuates considerably as well.

Excise tax effects on good Y:

Good Y's price will rise if the excise tax is applied. The quantity needed will significantly decrease since the demand is elastic.
