please help with math question

Answer:

For Question 3, all you have to do is subtract 5 from both sides of the equation, then divide by -3, which will leave you with 5 as the answer.

-3x + 5 = -10

-3x = -15x

x = 5

Answer:  multiply

Step-by-step explanation:

jus 45 multiply by 67

Answer:

1. Add x on both sides.

2.  Divide both sides by 4.

3. Add 20 to both sides.

4. Divide both sides by 3.

Step-by-step explanation:

Complex Numbers

A complex number z in polar form is expressed as

[tex]z=r(\cos\theta+\mathbf{i}\sin\theta)[/tex]

The nth power of a complex number in polar form is:

[tex]z^n=r^n(\cos(n\theta)+\mathbf{i}\sin(n\theta))[/tex]

If the complex number is given in rectangular form

[tex]z=x+\mathbf{i}y[/tex]

then the values of r and θ are given by:

[tex]r=\sqrt{x^2+y^2}[/tex]

[tex]\displaystyle \theta=\arctan\left(\frac{y}{x}\right)[/tex]

The given complex number is:

[tex]z=1-\mathbf{i}\sqrt{3}[/tex]

The value of r is:

[tex]r=\sqrt{1^2+(-\sqrt{3})^2}[/tex]

[tex]r=\sqrt{1+3}=2[/tex]

r=2

Calculating the angle:

[tex]\displaystyle \theta=\arctan\left(\frac{-\sqrt{3}}{1}\right)[/tex]

[tex]\displaystyle \theta=\arctan(-\sqrt{3})[/tex]

Since the number is in the quadrant IV, the angle is:

[tex]\theta=-60^\circ[/tex]

Thus, z is expressed in polar form as:

[tex]z=2(\cos(-60^\circ)+\mathbf{i}\sin(-60^\circ))[/tex]

Calculating:

[tex]z^3=2^3(\cos(-180^\circ)+\mathbf{i}\sin(-180^\circ))[/tex]

Given cos 180°=-1 and sin(-180°)=0

[tex]z^3=8(-1+0)[/tex]

[tex]z^3=-8[/tex]

The correct explanations are;

A) Vertical angles.

B) Corresponding angles theorem

C) Transitive property.

What are Parallel lines?

Parallel lines are those lines that are equidistance from each other and never intersect each other.

Given that;

Two lines x and y are parallel.

w is transversal of x and y.

Now, To prove ∠4 ≅ ∠5 we use;

Since, Two lines x and y are parallel.

So, We can apply all the properties of angles of triangles.

  Statements                                 Reasons

1. x || y                                           1. Given

2. w is transversal                         2. Given

3. ∠4 ≅ ∠1                                    3. Vertically opposite angles.

4. ∠1 ≅ ∠5                                    4. By Corresponding angles theorem.

5.  ∠4 ≅ ∠5                                  5. By Transitive property.

Thus, The correct explanations are;

A) Vertical angles.

B) Corresponding angles theorem

C) Transitive property.

Answer:

undefined

Step-by-step explanation:

Horizontal lines have no slope. The line on the graph is vertical, so we can't really tell what slope it is. But there isn't any run and only rise, therefore the slope is "undefined."

Answer:

C). The store across town is 8.6 miles away and takes about 24 minutes to get there.

D). Your car averages about 22 miles per gallon in the city Gas is $3.05 per gallon.

Step-by-step explanation:

The information regarding the distance of the store across town from the house, the time required to reach there, the average of the car, and the cost of gas per gallon would assist in calculating if the extra drive is worth buying chicken from the city store.

Cost of chicken in the city store - $2.99 per pound

Average of the car in 1 gallon = 22miles

so, the average of the car in 1 mile = 1/22

Cost of traveling 8.6miles = 8/22 * $3.05

                                           = 24.40/22

Additional cost = $ 1.109

Total cost of buying chicken from the city store = $2.99 + $1.10

                                                                                = $4.09

Hence, it is not worth to buy the chicken from the store across the town as it is costlier in comparison to $3.79 in nearby store.

Answer:

Step-by-step explanation:

1290

Based on the amount invested, the rate, and the period of compounding, after 11 years, the account would be $1,290.

As the rate is compounded daily, the rate and the period need to be converted to daily figures:

Rate = 5.8% / 365 days = 5.8/365 %

Period = 11 x 365 = 4,015 days

The amount in 11 years is:

= Amount x ( 1 + rate) ^ period

= 680 x (1 + 5.8/365%) ⁴⁰¹⁵

= $1,286.965

= $1,290

In conclusion, the account would have $1,290.

The sum of two complementary angles is 90 degrees.

Angle A  +  Angle B = 90

Let Angle B = X

5x + 2 + x = 90

Combine like terms:

6x +2 = 90

Subtract 2 from both sides:

6x = 88

Divide both sides by 6:

x = 88/6

x = 14.67

Angle B = 14.67 degrees ( rounded to the nearest hundredth)

The the direction of the resultant force is A. approximately 37.33° above the ground.

A resultant force simply means the single force that has same effect as two or more forces that are acting together.

In this case, a student pulls with a force of 40 pounds at an angle of 30° above the ground, and the other student pulls with a force of 35 pounds at an angle 45° above the ground.

The direction of the resultant force is 37.33° above the ground.
