Answer:

  cot(θ) = 4/5

Step-by-step explanation:

In the polar/rectangular coordinate representation (x, y) ⇔ (r; θ), we know that ...

  (x, y) = (r·cos(θ), r·sin(θ))

From the various trig definitions and identities, we also know that ...

  cot(θ) = cos(θ)/sin(θ) = (x/r)/(y/r) = x/y

For the given (x, y) = (-4, -5), the cotangent is ...

  cot(θ) = -4/-5 = 4/5

Answer:

Percent Decrease

Answer:

3+20-4x=19-4x+4 3+20=19+4 23=23 xeR

Answer:b=7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(3b−1)=40

(2)(3b)+(2)(−1)=40(Distribute)

6b+−2=40

6b−2=40

Step 2: Add 2 to both sides.

6b−2+2=40+2

6b=42

Step 3: Divide both sides by 6.

6b/6=42/6

b=7

Answer:

It is not possible

Step-by-step explanation:

Required

Convert 0.8km to hours and minutes

One of the condition for a successful conversion is that: only units of the same metric can be converted.

i.e.

Meters can be converted to feet (they both measure distance)

Days can be converted to years (they both measure time)

Pounds can be converted to grams (they both measure weight)

But in the given question, you attempt to convert from distance to time.

This is not possible, because time and distance are different measurements

Answer:

Step-by-step explanation:

The first three cuboid prisms all use the same area formula:

  A = 2(LW +H(L+W))

__

1. A = 2(3·3 +7(3+3)) = 2(9 +42) = 102 . . . cm²

2. A = 2(2·8 +10(2 +8)) = 2(16 +100) = 232 . . . in²

3. A = 2(4.9·3 +0.7(4.9 +3)) = 2(14.7 +5.53) = 40.46 . . . ft²

__

4. The area of this prism is the total of the area of the two triangular bases  and the areas of the rectangular faces. For triangle legs a, b and hypotenuse c, and prism depth d, the area formula can be written as ...

  A = ab +d(a+b+c)

  A = (8 mm)(15 mm) +(9 mm)(8 mm + 15 mm + 17 mm)

  A = (120 +9(40)) mm² = 480 mm²

Answer: $25.46

Step-by-step explanation:

Year 1 FCFE = 1.8 * (1 + 10%) = $1.98

Year 2 FCFE = 1.98 * 1.1 = $2.18

Year 3 FCFE = 2.178 * 1.1 = $2.40

Year 4 FCFE = 2.3958 * 1.05 = $2.52

Year 5 FCFE= 2.51559 * 1.05 = ‭2.64

Terminal Value = (2.64 * 1.03) / (12% - 3%)

= $30.21

Now discount all these cashflows to find the value:

= (1.98 / 1.12) + (2.18 / 1.12²) + (2.40 / 1.12³) + (2.52 / 1.12⁴) + (2.64 / 1.12⁵) + (30.21 / 1.12⁵)

= $25.46

Answer:

The median

Step-by-step explanation:

It uses all the added numbers as one

Answer:

Question one = 35a - 15

Question two = 9

Step-by-step explanation:

Distributive property means to multiply all the numbers inside the parenthesis

by the outside number. 5 x 7a equals 35a and 5 x 3 = 15.

35 x 9 - 315 - 15 = 300

A = 9

Explanation:

This isn't really an explanation, but I don't really know how to explain. The other answers just aren't correct (They aren't right triangles).

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Answer:

Since the annual profit for the FIRST YEAR is $322,000 and it increases 21% every year for 26 years, you do so to find the answer to the question.

Step-by-step explanation:

21% per year

26 years

21 x 26 = 546

Now you have to find 546% of 322,000 and add that to 322,000.

546% of 322,000 is 1,758,120.

Answer:

$216,265,829

Step-by-step explanation:

To find the sum of a geometric series we use the following equation

[tex]a*\frac{1-r^n}{1-r}[/tex]

we have

[tex]322000*\frac{1-1.21^{26}}{1-1.21}\\\\322000*671.633=216265829[/tex]

Answer:

B (2)

Step-by-step explanation:

The formula for circumference of a circle is C=2piR

Replace R with 2

C=2pi(2)

C=12.5664

Formula for area of a circle is A=piR^2

A=pi(2)^2

A=12.5664

Answer:

But Mars has no magnetosphere, and its atmosphere is over 100 times thinner than Earth's atmosphere. The trip to Mars and the stay on Mars will mean extended radiation exposure. Astronauts will need special habitats, suits, and machines that will protect them from radiation, which otherwise could cause cancer.
