Can someone pls help me

Answer:

x = - 7, x = - 1

Step-by-step explanation:

To find the zeros let f(x) = 0 , that is

x² + 8x + 7 = 0

Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)

The factors are + 7 and + 1 , since

7 × 1 = + 7 and 7 + 1 = + 8 , then

x² + 8x + 7 = 0

(x + 7)(x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x + 1 = 0 ⇒ x = - 1

Answer:

A triangle with angles measuring 55°, 60°, 65° degrees

Step-by-step explanation:

Two obtuse angles means two angles over 90°

The sum of all angles in a triangle are 180°

90°+90° itself is 180°, so we cant have two angles greater than 90°

Two right angles means 90° and 90° which is 180°, not possible

55°+60°+65° = 180° so it is possible.

Answer:

1. His tax is $37,490.

2. His average effective tax rate is 22%

3. His average tax rate is 24.93%

4. His marginal tax rate is 35%.

5. His tax liability will fall by $170

6. His tax liability will fall by $500.

Step-by-step explanation:

Note: This question is not complete. See the attached pdf file for the complete question.

The explanation of the answer is now given as follows:

1. What is his tax?

Note: See the attached excel for Mr. Hoosier's Tax Computation Based on the Tax Table in the question.

From the attached excel file, the Net tax is $37,490 which is his tax.

Therefore, his tax is $37,490.

2. His average effective tax rate

His average effective tax rate = Tax /  (Taxable income + Tax exempt income) = Tax /  (Taxable income +Municipal Bond interest) = $37,490 / ($150,400 + $20,000)  = 0.2200, or 22%

3. His average tax rate

Average tax rate = Tax / Taxable Income = $37,490 / $150,400 = 24.93%

4. His marginal tax rate

His marginal tax rate is 35% as in the tax computation used based on the tax table.

5. Assume he discovers that he is eligible for a 500 tax deduction. How much does his tax liability fall with that addition?

Taxable income = 150400 - 500 = $149,900

Based on the tax table in the question, we have:

Tax = 8850 + (149900 - 55000) * 30% = $37,320

Reduction in tax liability = $37,490 - $37,320 =$170

Therefore, his tax liability will fall by $170

6. Now he discovers that he is eligible for a $500 tax credit. How much does his tax liability fall due to this credit?

The purpose of the tax credit is to make tax liability reduced dollar by dollar.

Therefore, if he discovers that he is eligible for a $500 tax credit, his tax liability will fall by $500.

Complete Question:

Find the coordinates of the point after the described reflection. Give the distance between the point and its reflection. R(-5, 8) is reflected across the x-axis _____________.

Answer:

[tex](a)[/tex] [tex]R' = (-5,-8)[/tex]

[tex](b)[/tex] The distance is 16 units

Step-by-step explanation:

Given

[tex]R = (-5,8)[/tex]

Solving (a): Reflection across x-axis

The rule is:

[tex]R(x,y) ==> R(x,-y)[/tex]

So, the reflection of [tex]R = (-5,8)[/tex] is:

[tex]R' = (-5,-8)[/tex]

Solving (b): The distance between R and R'

Distance (d) is calculated as:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

Where:

[tex]R = (-5,8)[/tex] ---- [tex](x_1,y_1)[/tex]

[tex]R' = (-5,-8)[/tex] --- [tex](x_2,y_2)[/tex]

This gives:

[tex]d = \sqrt{(-5- -5)^2 + (-8- 8)^2}[/tex]

[tex]d = \sqrt{(0)^2 + (-16)^2}[/tex]

[tex]d = \sqrt{256}[/tex]

[tex]d = 16[/tex]

The distance is 16 units

Answer:

14 points

Step-by-step explanation:

To Find how many points did he/she score per game

Since rate = per (1)

We have to divide points by games

Since Mouna scored 42 point → Total and Games → 3

We have to divide 42 by 3

42/3 = 14

Hence, Mouna scored 14 points per game

Answer:

Sample space: {Black, Red, Blue, Brown, Purple, Yellow, Green}

Simple event

Step-by-step explanation:

Sample space is a list of all the possible outcomes.

This is a simple event because you are only doing one event, such as choosing marbles from a bag.

A compound event would be multiple simple events, such as flipping a coin and rolling a dice.

Answer:

3

Step-by-step explanation:

Use Pythagorean theorem

Base²+ altitude² = hypotenuse²

Base² + (√3)²   = (2√3)²

Base² + √3 *√3 = 2√3 *2√3

Base² + 3           = 4*3

Base² + 3           = 12

              Base²  = 12 - 3

              Base²  = 9

              Base    = [tex]\sqrt{9}=\sqrt{3*3} =3[/tex]

Answer:

The correct option is;

C. This advanced training seminar did not reduce response time, t(35) = -1.43, p > 0.05

Step-by-step explanation:

The given parameters are;

The population mean response time, μ = 9 minutes

The number of police officers in the sample, n = 36

The mean response time after the training, [tex]\overline x[/tex] = 8 minutes

The standard deviation of the response time after the training, s = 4.2 minutes

The level of significance, α = 0.05

The null hypothesis; μ ≥ 9

The alternative hypothesis; μ < 9

The test statistic for the t-test is [tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex], therefore, we get;

[tex]t=\dfrac{8-9 }{\dfrac{4.2}{\sqrt{36}}} \approx -1.42857142857[/tex]

The degrees of freedom, df = n - 1 = 36 - 1 = 35

The critical-t at 0.05 level of significance is critical-t = 1.69, p(t < -1.43) > 0.05

and, we fail to reject the null hypothesis, therefore, the advanced training did not reduce the response time

Answer:

The answer will be ( n - 4 ) ( 3n² + 2 ).

Step-by-step explanation:

1) Factor out common terms in the first two terms, then in the last two terms.

[tex] {3n}^{2} (n - 4) + 2(n - 4)[/tex]

2) Factor out the common term n - 4.

[tex](n - 4)( {3n}^{2} + 2)[/tex]

Therefor, the answer is ( n - 4 ) ( 3n² + 2 ).

Answer:

7.8. 10 ^ 3 m / s

Step-by-step explanation:

The computation of the average speed in m/s is shown below:

The average speed equation is

= ΔS ÷ Δt;

As We know that

an entire revolution would be40,000 km

and a satellite takes 85 minutes to complete a revolution,  

So,

ΔS = 40,000 km = 40,000,000 m

Δt = 85 min = 5 100 s

Now the average speed is

= 40 000 000 ÷ 5 ÷ 5 100

 = 7843.14 m / s

= 7.8. 10 ^ 3 m / s

Answer:

1.230 euros

Step-by-step explanation:

De la pregunta anterior se nos dice que:

Yolanda compró un coche por 8.200 euros. Lo ha pagado en tres partes.

Paso 1

Sea el porcentaje de la suma total de dinero = 100%

Primero pagó el 60% del valor del auto, luego el 25% y finalmente el resto.

Dejemos que el resto esté representado por x

Por eso;

Primera parte + Segunda parte + Tercera parte = 100%

60% + 25% + x = 100%

x = 100% - (60% + 25%)

x = 100% - 85%

x = 15%

Paso 2

¿Cuánto pagó Yolanda la última vez?

La última vez = Tercera parte y esto se calcula como:

15% de 8.200 euros

= 15/100 × 8.200 euros

= 1.230 euros

Yolanda pagó 1.230 euros la última vez.
