Evalute 99³ using identity​

Answers

Answer 1

Answer:

970299

Step-by-step explanation:

We have,

[tex]99^{3}[/tex]

[tex]= (100 - 1)^3[/tex]

We know that,

[tex](a-b)^3 = a^3 - b^3 -3ab (a-b)[/tex]

Therefore,

[tex](100)^3 - 1^3 - 3(100)(1)(100-1)[/tex]

[tex]1000000 - 1 - 300(100-1)[/tex]

[tex]1000000 - 1 - 30000 + 300[/tex]

[tex]=970299[/tex]

the volume of the cube is 8 ft^3. what the length of each side?

Answers

Answer:

2 feet

Step-by-step explanation:

Use the cube volume formula, V = s³, where s is the side length.

Plug in 8 as V, and solve for s:

V = s³

8 = s³

Take the cubed root of each side:

2 = s

So, the length of each side is 2 feet.

Answers

Answer:

3-3x and 3

Step-by-step explanation:

f(x) = 3x-3

g(x) = -x

g(f(x)) in your g(x) substitute x with f(x)

g( f(x) ) = g( 3x-3) = -(3x-3) = -3x+3

is the the second choice from top because -3x+3 is the same with 3 -3x

g(f(x)) =3-3x

g(f(0)) always work from inside first, so first find f(0) than g(f(0))

f(0) = f(x=0) = 3*0-3 = -3

Now we do the g(f(0)) = g( -3) is the same as  

g(x) except that we substitute x for -3, g(x= -3) = -(-3) =3

g(f(0))=3

*an easier way to find the answer for the second problem would have been that we knew that f(g(x) ) = 3-3x so f(g(0)) =3-3*0 = 3

Answer:

the answer for this is D.

Step-by-step explanation:

it is a combination of letters operations and variables.But it is not equated (=) to something that is why it is not an algebraic equation.It is also not a numerical equation or numerical expression because it does not consist of only numbers.

3s(4+6)² is an example of an algebraic expression.

What is an algebraic expression?

"An algebraic expression is an expression built up from integer constants, variables, and the algebraic operations."

The given expression is:

3s(4+6)²

The given expression is not an equation as it does not contain an equal sign. It is an expression.

Therefore, it is neither algebraic nor numerical equation.

Now, it contains a variable 's'.

Therefore, it is not a numerical expression.

tính z=(〖(1+i)〗^10-1)/(〖(1+i)〗^10+1)

Answers

It looks like the given complex number is

z = ((1 + i )¹⁰ - 1) / ((1 + i )¹⁰ + 1)

Let w = 1 + i, so we rewrite

z = (w ¹⁰ - 1) / (w ¹⁰ + 1)

Since w * = 1 - i, we get w w * = (1 + i ) (1 - i ) = 1 - (-1) = 2. Multiply z by ((w *)¹⁰ + 1) / ((w *)¹⁰ + 1). This gives

z = (2¹⁰ - 1 + w ¹⁰ - (w *)¹⁰) / (2¹⁰ + 1 + w ¹⁰ + (w *)¹⁰)

Now, writing w in polar form yields

w = √2 exp(i π/4)

==>   w ¹⁰ = (√2)¹⁰ exp(i 10π/4) = 2⁵ exp(i 5π/2) = 2⁵ i

Similarly,

w * = √2 exp(-i π/4)

==>   (w *)¹⁰ = -2⁵ i

So we have

w ¹⁰ + (w *)¹⁰ = 0

w ¹⁰ - (w *)¹⁰ = 2 × 2⁵ i = 2⁶ i

Then we end up with

z = (2¹⁰ - 1 + 2⁶ i ) / (2¹⁰ + 1) = (1023 + 64i ) / 1025

The Probability that a data value is between 27 and 28 is 9.3%.

What is Probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 to 1,

Here, mean of the data is 26

P(0 ≤ x - μ ≤ σ/2) = 0.195

P(0 ≤ x - μ ≤ σ/4) = 0.0987

P(σ/4 ≤ x - μ ≤ σ/2) = 0.093

Thus, the Probability that a data value is between 27 and 28 is 9.3%.

In fact they do not even know what random data is.

Answers

Answer:

Following are the responses to the given question:

Step-by-step explanation:

In the first example, a team walks into a bar & chooses the random person to speak, in which situation, the woman who walks to the club has made a choice, he has selected a people with and who he wants to speak, it is a subjective preference. A choice cannot be random in statistical since it has a subjective preference. The first interpretation may therefore be randomized in general, but not arbitrary in statistics.

In the second example, i.e., the definition of Building tracks Example, a randomized wood piece is an identical piece or is different in size from other pieces. In this, piece wood has been differentiated by one's looks so, when asked to pick a random piece, we are likely to choose a non-uniform part rather than the uniform one. It is a random racial bias, so again in constructing pursuits the second definition could be random, but not a discrete one in stats.

In the identification numbers of random, we intentionally state that equal probability for each unit in the population of inclusion in the sampling. The definition essentially includes all sorts of predilection, and therefore refers to true allegiance, when we neither make that choice nor want to choose a separate unit.

Joseph runs 2 1/2 miles on Monday. Each day after that, he runs the same 1 1/3 mile route every morning. His goal is to run at least 6 miles
by the end of the week. Which inequality represents the least number of days after Monday that Joseph needs to run to reach his goal?

Answers

Answer:

Joseph must run at least 3 more days to achieve 6 miles per week.

Step-by-step explanation:

Since Joseph runs 2 1/2 miles on Monday, and each day after that, he runs the same 1 1/3 mile route every morning, and his goal is to run at least 6 miles by the end of the week, to determine which inequality represents the least number of days after Monday that Joseph needs to run to reach his goal, the following calculation must be performed:

1/2 = 0.5

2 1/2 = 2.5

1/3 = 0.333

1 1/3 = 1.333

(6 - 2.5) / 1.333 = X

3.5 / 1.333 = X

2.625 = X

Therefore, Joseph must run at least 3 more days to achieve 6 miles per week.

Answers

Answer:

The probability that exactly two have flaws is P (x=2) = 0.2376

Step-by-step explanation:

Here

Success= p= 0.15

Failure = q= 0.85

total number= n= 8

Number chosen = x= 2

Applying the binomial distribution

P (x=x) = nCx p^x(q)^n-x

P (x=2) = 8C2 0.15 ²(0.85)^8

P (x=2) = 0.2376

The success is chosen about which we want to find the probability. Here we want to find the probability that exactly two have flaws so success would be having flaws therefore p = 0.15

Answers

Answer:

P = 40.56 ft

Step-by-step explanation:

The figure is composed of a rectangle and half circle

The perimeter of the figure = the length of the borders round the figure

W = 8 ft

L = 10 ft

½(perimeter of circle) = ½(πd) = ½(3.14*8)

= 12.56 ft

Perimeter of the figure = 8 + 2(10) + 12.56

= 8 + 20 + 12.56

A certain factory produces and sells 8000 cars per month, making a monthly net profit of P dollars. They sell
each car for n dollars and it costs them c dollars to produce a single car.
Write an equation that relates P. n, and c.

Answers

Answer:

p= 8000n-8000c

Step-by-step explanation:

8000

p= n - c

or

p= 8000n-8000c

Esentially you need to subtract n, the amount they sell each car for by c, the amount it costs to produce a car, (which should be less because the company has to make money) this would give you the total they make a month, P.

Because the amount of cars is constant, 8000, you can always multiply the cost of the car and how much its sold for by 8000. Otherwise, you would have another variable like k, which would be how many cars sold

He was just getting ready to drop it on the floor, and end its life in the usual way, when it shook itself in the spoonspread two wet wings, and flopped onto the tablecloth.
