which system of equations can be used to solve for j and w?

Answer:

b = [tex]\frac{V}{dt}[/tex]

Step-by-step explanation:

Divide both sides by dt, so it cancels out.

[tex]\frac{V}{dt} = \frac{bdt}{dt}[/tex]

[tex]\frac{V}{dt} = b[/tex]

Answer:

Approximate: C ≈ 50.27

Exact: C = 16π

Step-by-step explanation:

C = 2πr

We know that r is 8

C = 2π8

C = 16π

C ≈ 50.27

The circumference of a circle is 16π unit²

The circumference of a circle is defined as the linear distance around of circle.

Formula of circumference of a circle (C) = 2πr

Where r is radius of circle

Given radius of circle (r) = 8,

Substitute the value of r,

C = 2π(8)

C = 16π unit²

Substitute π = 3.14,

C ≈ 50.27 (approximate)

Thus, the circumference of a circle is 16π unit²

Answer:

3/20

Step-by-step explanation:

Answer:

3/20

Step-by-step explanation:

The circle is a whole, or 1

1 - 1/4 - 3/5 = area shaded

1 - 5/20 - 12/20 = area shaded

1 - 17/20 = area shaded

3/20 = area shaded

Another method:

1 - 0.25 - 0.6

1 - 0.85 = 0.15

0.15 = 3/20

Answer:

In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the si…

Answer: Hope This Helps!

Step-by-step explanation:

Pythagoras Theorem Statement Pythagoras theorem states that “ In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides “. The sides of this triangle have been named as Perpendicular, Base and Hypotenuse.

First, you should take 30% of the original price, which would be 600. (You should be able to use a standard calculator for this). Next, since the price increases by 30%, just put 600+30% and your answer should be 780.

PS I just tried this problem on my calculator, so I don't know if I did it right, but it makes sense to me. I also searched it up and it also says it's 780, so I'm guessing it's correct. The way I showed you is easier though.

Answer:

22.5 cm²

Step-by-step explanation:

La fórmula para el volumen de un prisma con una base hexagonal = Área de la base × Altura

De la pregunta anterior

Área de la base =?

Altura = 3 cm

Volumen = 67.5 cm³

Área de la base = Volumen ÷ Altura

Área de la base = 67.5 cm³ ÷ 3cm

= 22.5 cm²

Por lo tanto, el área si es base = 22.5 cm²

Radius = 21

Step-by-step explanation:

Volume of a sphere = 4/3 * pie * radius^3

12,348 pie = 4/3 * pie * radius ^3

12,348 = 4/3 * radius^3

(12,348 * 3)/ 4 = radius^3

9261 = radius^3

radius = [tex]\sqrt[3]{9261}[/tex]

radius = 21

The exponent function will be f(x) = 1/3 (4)ˣ. Then the correct option is C.

Let b is the base and x is the power of the exponent function and a is the leading coefficient. The exponent is given as

y = a(b)ˣ

At x = 1, the value of y will be 4/3. Then we have

4/3 = ab   ...1

At x = 2, the value of y will be 16/3. Then we have

16/3 = ab²  ...2

From equation 1 and 2, we have

b = 4 and a = 1/3

Then the function will be

f(x) = 1/3 × (4)ˣ.

Then the correct option is C.

Answer:

0.6832

Step-by-step explanation:

Given :

Mean, m = 52

Standard deviation, s = 7

-1.2 standard deviation of average = 57 - 1.2(7) = 57 - 8.4 = 48.6

2 standard deviations of average = 57 + 2(7) = 57 + 14 = 71

Zscore = (48.6 - 52) / 7 = - 0.486

Zscore = (71 - 52) / 7 = 2.714

P < -0.486) = 0.31348

P < 2.714 = 0.99668

P < 2.714 - P < -0.486 = (0.99668 - 0.31348) = 0.6832

Answer:

3 foot 3 inches

Step-by-step explanation:

How much deeper the hole should be = intended depth - current depth

Convert feet to inches for easy calculation

1 ft = 12 inch

5 x 12 = 60 inches

1 foot = 12

12 + 9 = 21 inches

60 - 21 = 39 inches

convert inches to feet

39 /12 = 3 feet 3 inches
