Answer:

5.101 x 10^14 m^2

Step-by-step explanation:

First you have to convert km to metres (the final answer must in metres).

So that would be 12742000m. Remember this is the diameter. The radius is half the diameter. So the radius would be 6371000m.

You then put it into the formula: 4 x π x 6371000².

And then you would get the answer: 5.101 x 10^14 m^2

Answer:

The ratio of corresponding sides is 2:3

Step-by-step explanation:

Given, the corresponding medians of two similar triangles are in ratio of = 2:3

We know that,

The ratio of corresponding median = ratio of their corresponding altitude

So the ratio of the corresponding median is equal to the corresponding altitude is 2:3.

So, the ratio of their corresponding sides will also be 2:3.

And the ratio of the area of two triangle = square of the ratio of their corresponding sides.

Answer:

It's the second one.

Step-by-step explanation:

It's the second one because the volume of the radius is v and 4/3 gives the radius and after that if you look at the second three then use a calculator to multiple the numbers up it tells you what the numbers are and the number give you r for the volume so it makes it the second one.

Answer:

The correct option are;

f(x) = x² - 4 and g(x) = x - 3, (f ο g)(2) = -3 and (g ο f)(2) = -3, so the function is commutative

Given f(x) = 4·x and g(x) = x², (f ο g)(x) = 4·x² and (g ο f)(x) = 16·x²

So the function is not commutative

Step-by-step explanation:

For the equations f(x) = x² - 4 and g(x) = x - 3, we have;

(f ο g)(x) = f(g(x)) = (x - 3)² - 4 = x² - 6·x + 9 - 4 = x² - 6·x + 5

At x = 2, we have;

(f ο g)(2) = f(g(2)) = 2² - 6×2 + 5 = - 3

Similarly, we have;

(g ο f)(x) = g(f(x)) = x² - 4 -3 = x² - 7

At x = 2, we have;

(g ο f)(2) = g(f(2)) = 2² - 7 = 4 - 7 = -3

Therefore, by commutative property, we have that the result of an operation does not change by changing the order of the operands such that we have;

a + b = b + a or a·b = b·a from which we have resolved also the following operation is commutative

(f ο g)(2) = (g ο f)(2)

Similarly given f(x) = 4·x and g(x) = x², (f ο g)(x) = 4·x² and (g ο f)(x) = 16·x²

So the function is not commutative

(f ο g)(x) = f(g(x)) = 4·x²

(f ο g)(x) = 4·x²

(g ο f)(x) = g(f(x)) = (4·x)² = 16·x²

(g ο f)(x) = 16·x²

∴ (f ο g)(x) = 4·x² ≠ (g ο f)(x) = 16·x²

(f ο g)(x)  ≠ (g ο f)(x) the function is not commutative.

Answer:

Given f(x) = 4x and g(x) = x², (f ∘ g)(x) = 4x² and (g ∘ f)(x) = 16x², so function composition is not commutative.

Answer:

f−1(y)=4(y−7) is the inverse function

Answer:

The similarities are

1) The length of E and F can be described by two parallel lines spaced 3 blocks apart where the parallel line on the left of both E and F is 2 blocks long, while the parallel line on the right is one block long

2) Both height of E and F can be described by two parallel lines spaced 2 blocks apart  where the parallel line on the top of both E and F is 3 blocks long, while the parallel line at the bottom is one block long

3) The interior of E an F can be described by parallel lines 2 blocks long in the horizontal portion and one block long in the vertical portion

The differences are

1) The difference between E and F is that the parallel lines used for the construction of E are all one block higher than that of F

2) The other difference is that all the lines used for the construction of the figure E are 3 blocks to the left of those used for the construction of F

Figure F is essentially the translation of figure E three blocks to right and one block down

Step-by-step explanation:

Answer:

x = 26

Step-by-step explanation:

Start with - 9 + x = 17,   or   -9 + x = 17

Solve for x by isolating x on the left side.  To do this, add 9 to both sides, obtaining x = 26

Answer:

Well, Two integers are relatively prime (or coprime) if there is no integer greater than one that divides them both (that is, their greatest common divisor is one). For example, 12 and 13 are relatively prime, but 12 and 14 are not.

Answer:

x ≤ 4/7

Step-by-step explanation:

Simplify the given 2x ≤ -2/3 (4x + 4) by multiplying both sides by (3/2):

(3/2)(2x) ≤ (3/2)(-2/3)(4x + 4)

We get 3x ≤ -4x - 4

Solve for x by combining like terms.  Add 4x to both sides, obtaining

7x ≤ 4

and so the solution is the set

x ≤ 4/7

Answer:

80 + 30 n ≥ 250

Video tape cost = $35

1st day for camera ranting = $45

Additional daily cost = $30

Find:

Inequality

Number of days

Computation:

Assume number of days = n

So,

35 + 45 + 30 n ≥ 250

80 + 30 n ≥ 250

30 n ≥ 170

n = 5 days

Number of days = 5

8. r = [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Answer:

p = 0.8333333333

Step-by-step explanation:

Simplifying

1 = 6(1 + -1p)

1 = (1 * 6 + -1p * 6)

1 = (6 + -6p)

Solving

1 = 6 + -6p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '6p' to each side of the equation.

1 + 6p = 6 + -6p + 6p

Combine like terms: -6p + 6p = 0

1 + 6p = 6 + 0

1 + 6p = 6

Add '-1' to each side of the equation.

1 + -1 + 6p = 6 + -1

Combine like terms: 1 + -1 = 0

0 + 6p = 6 + -1

6p = 6 + -1

Combine like terms: 6 + -1 = 5

6p = 5

Divide each side by '6'.

p = 0.8333333333

Answer:

0.833

Step-by-step explanation:

Simplifying

1 = 6(1 + -1p)

1 = (1 * 6 + -1p * 6)

1 = (6 + -6p)

Solving

1 = 6 + -6p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '6p' to each side of the equation.

1 + 6p = 6 + -6p + 6p

Combine like terms: -6p + 6p = 0

1 + 6p = 6 + 0

1 + 6p = 6

Add '-1' to each side of the equation.

1 + -1 + 6p = 6 + -1

Combine like terms: 1 + -1 = 0

0 + 6p = 6 + -1

6p = 6 + -1

Combine like terms: 6 + -1 = 5

6p = 5

Divide each side by '6'.

p = 0.8333333333

Simplifying

p = 0.8333333333

Answer:

1.05 meters

Step-by-step explanation:

To convert centimeters to meters, we need to divide the number by 100.

So 105/100= 1.05

Answer:

105 cm = 1.05 m

Step-by-step explanation:

For this problem, it is important to know metric conversions.  Metric conversions are based on powers of ten.  The prefix centi- means 100 (Like how a century is 100 years), and in the metric system is used to represent one-hundredths.

To convert 105 centimeters to meters, we need to divide by 10^2 or multiply by 10^-2 (both are the same).

So we can say the following:

105 cm * 10^-2  =  1.05 m

Hence, 105 centimeters is 1.05 meters.

Answer:

El niño con 14 años es el que tiene más derechos según su edad.

Step-by-step explanation:

Aquí, tenemos un abuelo que quiere compartir una cantidad de dinero entre sus nietos y queremos saber cuál de sus nietos tiene más derecho a este dinero proporcionalmente.

Creo que va a utilizar la edad de los niños como valor de proporcionalidad.

Así, compartiendo la cantidad entre sus hijos, tenemos; 14: 10: 6 que es 7: 5: 3

Entonces, lo que esto significa es que el niño con 14 años tomará 7 de los 15 lugares y es el que tomará la cantidad más alta.

Entonces, usando la edad como criterio, el niño con 14 años tiene más derecho a la cantidad a compartir.
