Answer: y=4x-3

Step-by-step explanation:

point slope form is y-y1=m(x-x1)

y-1=(4)(x-1)

y-1=4x-4

y=4x-3

Answer:

Step-by-step explanation:

If x = -5

Entonces f(X) = (-5) - 5 = -10

If x = 0

So f(x) = (0) - 5 = -5

When x = 5

So f(x) = (5) - 5 = 0

Don't pay attention to the "F", it just means they want the whole result of the operation if you replaced "x" with a number.

Remember that there are negative and positive numbers.

Any number below zero is negative.

5 x 2 = 10

4 x 2 = 8

Answer:

A is -8

B is 28

Step-by-step explanation:

Let us rewrite the equation in the standard format of y = mx + b

By = -Ax + 12

y = (-A/B)x + 12/B

Now, since the line is parallel to the line given below, then their slopes must be equal

2x - 7y = 3

7y = 2x - 3

y = (2/7)x - 3/7

slope here is 2/7

Thus;

-A/B = 2/7

let’s now insert the point that the line passes through

We have;

1 = (-A/B)2 + 12/B

but -A/B = 2/7

1 = 4/7 + 12/B

12/B = 1 - 4/7

12/B = 3/7

B = (7 * 12)/3

B = 28

-A/28 = 2/7

-7A = 56

A = 56/-7

A = -8

Answer:

No, it is 6.60

Step-by-step explanation:

We need to know the cost of 1 pound, so we have to do 3.60 divided by 3, to get the cost of 1 pound, which is 1.20

We times 1.20 by the amount of pounds we need, (5.5,) and get 6.60.

If it was times just 5 pounds, than yes, it would be correct, but we need to look out for decimals too.

Answer:

d. $6.60

Step-by-step explanation:

3 cost 3.60, then 5.5 would cost ?

So we have to find what multiplied with 3 would equal 5.5, so:

5.5/3, we can't simplify this fraction so we'll just use it to multiply 3.60

3.60 × 5.5/3 = 19.8/3 = 6.6

Answer:

θ = 17.45°

Step-by-step explanation:

Given that,

Length of a ladder = 40 foot

Height of a building = 12 feet

We need to find the angle of elevation that the ladder makes with the ground.

40 foot will be the hypotenuse and 12 feet will be the perpendicular distance.

Using trigonometry for this:

[tex]\sin\theta=\dfrac{P}{H}\\\\\sin\theta=\dfrac{12}{40}\\\\\theta=17.457^{\circ}[/tex]

So, the angle of elevation that the ladder makes with the ground is 17.45°.

The angle of elevation is [tex]17^\circ[/tex] to the nearest degree

The right-angled triangle formed can be solved for the angle of elevation if we note that

So, the trigonometric ratio to be used here is the [tex]sin\theta[/tex]. That is

[tex]sin\theta=\dfrac{\text{height of the building}}{\text{length of ladder}}[/tex]

substituting the values

[tex]sin\theta=\dfrac{12}{40}\\=\dfrac{3}{10}[/tex]

Now, to find the angle of elevation, [tex]\theta[/tex]

[tex]\theta=sin^{-1} \left(\dfrac{3}{10} \right)\\\approx 17^\circ \text{ (to the nearest degree)}[/tex]

The messenger traveled a total of 100 floors while delivering packages.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A messenger entered a building on the ground floor zero.

He delivered a package to someone on the 15th floor which is (0 + 15).

= 15 floors.

That person sent him with a package to the 3rd floor, which is (15 - 3) = 12 floors.

∴ Total floors he traveled (15 + 12) = 27 floors.

who then sent him up to the 38th floor, so from 3rd to 38th he traveled

(38 - 3) = 35 floors.

∴ Total distance he traveled is = (27 + 35) = 62 floors.

Now he is on the 38th floor so, to reach zero level he needs to travel 38 floors.

Total distance traveled by him is = (62 + 38) = 100 floors.

Answer:

Common stockholders received $1,600.

Step-by-step explanation:

Cumulative preferred stock can be described as a type of preferred stock in which dividends not paid in any year accumulate and has to be paid first in future before common stockholders receive any dividends.

Since the dividends paid in cash by Alpha Corporation includes one- year dividends in arrears to preferred stockholders, this implies that the cumulative preferred stockholders have to paid 2-year dividends, i.e. the one-year arrears plus the current year dividend.

Amount received by common stockholders can be calculated as follows:

Amount of dividend paid by Alpha = $10,000

Annual cumulative preferred stock dividend = 1,500 * $40 * 7% = $4,200

Amount received by cumulative preferred stockholders = Annual cumulative preferred stock dividend * 2 years = $4,200 * 2 = $8,400

Amount received by common stockholders = Amount of dividend paid by Alpha - Amount received by cumulative preferred stockholders = $10,000 - $8,400 = $1,600

Therefore, common stockholders received $1,600.

The answer is the last one, D, pictured above on the question, I took the test and it showed it was the right one

Step-by-step explanation:

The geometric expression of two complex number is the magnitude r₁*r₂ and the phase is  θ₁ + θ₂.

The complex number is" the combination of real numbers and an imaginary number. The complex number is of the form a + i b".

According to the question,

z, w are the two complex numbers. The distance from its point in the complex plane to the origin (0,0) and the angle formed by the line segment from the origin to the point and the positive half of the x-axis.

The distance or 'magnitude' to the origin is denoted as 'r' and the angle or 'phase' formed denoted as 'θ'. The distance to the origin is called 'magnitude'.

The parameter 'r' and 'θ' related to 'a' along x-axis and 'b' along y-axis.

Euclidean distance formula applying Pythagorean theorem we have

r =  [tex]\sqrt{a^2+b^2}[/tex].

The sine angle is defined to the ratio y-coordinate 'b' to length  'r' and the cosine angle is defined to the ratio x-coordinate 'a' to length 'r'.

sin θ =  [tex]\frac{b}{r}[/tex]  and cos θ = [tex]\frac{a}{r}[/tex].

b = r sin θ; a = r cosθ

When multiplying two complex numbers we by multiplying magnitude together and add two phase. when divide two complex number by dividing the magnitude correspondingly and subtracting the phase from the numerator and the denominator.

Then we have product complex number to the magnitude r₁ and phase θ₁

with a complex number to the magnitude r₂ and the phase θ₂ which gives   the complex number with magnitude r₁ * r₂ and θ₁ + θ₂.

Hence, the geometric representation of z w is with magnitude r₁*r₂  and phase is θ₁ + θ₂.
