Answer:

3rd option

Step-by-step explanation:

x³ - 64x ← factor out x from each term

= x(x² - 64) ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

x² - 64

= x² - 8²

= (x - 8)(x + 8)

then

x³ - 64x = x(x - 8)(x + 8)

Answer:

8

Step-by-step explanation:

In order for the equation to be true, both sides need to have the same value of 45. So, you need to find what value of x makes that side of the equation equal 45.

To simplify this, I would start by adding 3 to both sides: 6x = 48.

Next, I would divide both sides by 6, giving us x=8.

Let, first find expression for both;

— The expression for seven cubed is 7³

— The expression for forty nine is 49

Now, sum of both is 7³ + 49

This is the required answer

Answer:   Less than sign

7/27 < 11/36

===================================================

Work Shown:

First assume the two fractions are equal

7/27 = 11/36

Let's cross multiply to get...

7*36 = 27*11

252 = 297

The last equation is false, so the original equation is false. We can fix things by replacing the equal sign with a less than sign (since 252 is less than 297), so we get this instead

7/27 < 11/36

7*36 < 27*11

252 < 297

Showing that 7/27 is smaller than 11/36. We can confirm this by converting everything to decimal form. Use a calculator.

7/27 = 0.259 approximately

11/36 = 0.306 approximately

We see that 7/27 has the smaller decimal representation.

Answer:

d = 2

Step-by-step explanation:

A = πr²

2r = d

Step 1: Define

A = π

Step 2: Find r

π = πr²

1 = r²

r = 1

Step 3: Find d

2(1) = d

d = 2

The correct statement for the given description is  [tex]\dfrac{n^3}{16}-2+8[/tex], while the value of the expression for x = 4 is 10.

A linear equation is one in which the variable's maximum power is always 1. A one-degree equation is another name for it.

The description of the statement is:

Now, the given statements of the problem can be written as,

Further, by combining all three statements, [tex]\dfrac{n^3}{16}[/tex]  is the quotient and 2 is subtracted and 8 is increased which means 8 is added.

Thus, the resultant expression is  [tex]\dfrac{n^3}{16}-2+8[/tex].

Evaluating the obtained expression at n=4,

For a standard normal distribution, the value of  [tex]P(Z\geq a)[/tex] will be equal to 0.2884.

A standard normal distribution table gives the information about the probability.

The normal distribution has a mean is equal to zero and the standard deviation is equal to 1.

In this case, it is given that

[tex]P(Z\leq a)=0.7116[/tex]

Now for finding the value we have

[tex]P(Z\geq a)=1-P(Z\leq a)[/tex]

Now by putting the value

[tex]P(Z\geq a)=1-0.7116[/tex]

[tex]P(Z\geq a)=0.2884[/tex]

Thus for a standard normal distribution, the value of  [tex]P(Z\geq a)[/tex] will be equal to 0.2884.

Answer:

3 graph

Step-by-step explanation:

A removable discontinuity is a point on the graph that is undefined or does not fit the rest of the graph.

The function in the graph that has a removable discontinuity is graph 3.

A removable discontinuity can be defined as a point on a graph of a function at which it is not connected. This ultimately implies that, a removable discontinuity refers to a point on the graph of a function that is considered to be undefined or doesn't accurately fit the other part of a graph.

However, it should be noted that the discontinuity in this graph can be corrected by filling in a single point.

h2 - 25

Trying to factor by splitting the middle term

1.1 Factoring h2 - h - 20

The first term is, h2 its coefficient is 1 .

The middle term is, -h its coefficient is -1 .

The last term, "the constant", is -20

: Multiply the coefficient of the first term by the constant 1 • -20 = -20

: Find two factors of -20 whose sum equals the coefficient of the middle term, which is -1 .

Answer:

f(x) = 270,000(1.07)^x

$330,761.61

Step-by-step explanation:

Exponential growth is pretty simple:

f(x) = 270,000(1.07)^x

, where x is the number of years

To find sales after 3 years, substitute 3 for x:

f(x) = 270,000(1.07)^3

f(x) = 270,000(1.225043)

f(x) = $330,761.61
