Is the expression x3 x3 x3 equivalent to x3 3.3? Why or why not? Explain your reasoning.

Answers

No the expression x³.x³.x³ is not equivalent to expression x³ˣ³ˣ³.

Given the expression:

x³.x³.x³

here we apply the law of exponent that, when bases are same powers are added.

Two exponential terms with the same base are multiplied, and while the base doesn't change, their powers are added. On the other hand, their powers are removed when two exponential expressions with the same base are split.

therefore, x³.x³.x³ = x ³⁺³⁺³

= x⁹

and in the second expression x³ˣ³ˣ³.

In this expression powers are multiplied.

= x³ˣ³ˣ³.

= x²⁷

therefore both expressions are not equivalent.

Hence the expressions are not equivalent.

an online retailer is shipping a shower curtain pole that is 13 feet long. their largest box is in the shape of a rectangular prism that is 10 ft × 9 ft × 8 ft. will the pole fit in the box?

Answers

Yes, the pole will fit in the box when kept diagonally.

In order to fit the pole in rectangular prism or cuboid, it has to be kept diagonally. Now, we need to calculate the length of body diagonal of cuboid. The length of body diagonal of cuboid should be greater than pole to fit it.

The length of body diagonal of cuboid can be calculated by the formula -

Diagonal = √(l² + b² + h²)

Keep the values in formula to find the diagonal of rectangular prism

Diagonal = √(10² + 9² + 8²)

Taking square of the three numbers to find the diagonal of rectangular prism

Diagonal = √100 + 81 + 64

Taking sum of numbers present on Right Hand Side of the equation

Diagonal = √245

Taking square root of the number

Diagonal = 15.65 feet

Hence, as the diagonal of rectangular prism is greater than shower curtain pole, it will definitely fit.

(c) How long does it take the coin to strike the ground? (Round your answer to two decimal places.)

Answers

Using the motion equation we can get:

a) s = -16*t^2 + 1028

b) 992 feet above the ground.

c) after 8 seconds, the coin will hit the ground.

How to write the height equation?

First, we know that the general height equation is:

s = -16*t^2 + v0*t + s0

In this case, the coin is dropped, so the initial velocity v0 is zero.

And the coin is dropped from a height of 1028 ft, then s0 = 1028

Replacing that in the equation we get:

s = -16*t^2 + 1028

b) The height after 1.5 seconds is what we get by evaluating the height equation in t = 1.5

s = -16*(1.5)^2 + 1028 = 992

This means that the height after 1.5 seconds is 992 ft above the ground.

c) The coin will strike the ground when s = 0, then we need to solve:

s = 0 = -16*(t)^2 + 1028

Solving that for t, w eget:

16*t^2 = 1028

t^2 = 1028/16

t = √(1028/16) = 8

This means that the coin will hit the ground after 8 seconds.

From the attached figure, we have the following coordinates

A = (5, 16)

B = (17, 10)

C = (14, 4)

D = (2, 10)

Calculate the lengths AB and BC using the following distance formula

d = √[(x2 - x1)^2 + (y2 - y1)^2]

This gives

AB = √[(5- 17)^2 + (16- 10)^2] = 13.4

BC = √[(14- 17)^2 + (4- 10)^2] = 6.7

The approximate length of string lights the staff needs to decorate the ceiling is then calculated as

P = 2 * (AB + BC)

Two different numbers are selected ffrom -2,-2,0,3,4,5 and multiplied together. what is the probability that the product is zero

Answers

Two numbers are drawn without replacement. The only way their product is zero is if one of these numbers is zero. The probability of this happening is

[tex]\dfrac{\dbinom11 \dbinom51}{\dbinom62} = \dfrac{1\cdot5}{15} = \boxed{\dfrac13}[/tex]

In other words,

• there is 1 zero in the list - we draw it with [tex]\binom11 = 1[/tex] way of doing so;

• there are 5 non-zero numbers in the list - we draw 1 of these, with [tex]\binom51 = 5[/tex] ways of doing so;

• there is a total of 6 numbers in the list - we draw 2 of these, with [tex]\binom62 = 15[/tex] ways of doing so.

On the other hand, if the numbers are drawn with replacement and independently of one another, then each number has the same probability of getting drawn each time. There are 6×6 = 36 possible outcomes, each with 1/36 probability of occurring. Their product is zero if at least one of the numbers drawn is zero. The probability of this happening is

[tex]\dbinom21 \dfrac16 \times \dfrac56 + \dbinom22 \left(\dfrac16\right)^2 = \dfrac{11}{36}[/tex]

That is,

• there is 1/6 chance of drawing a zero and 5/6 chance of not drawing a zero. This can selection can happen in [tex]\binom21=2[/tex] ways (zero is drawn first or last);

• there is 1/6 chance of drawing a zero for either selection. This can happen in [tex]\dbinom22=1[/tex] way (zero is drawn both times).

While the probabilities are close, they are not the same! Be careful with which interpretation you choose.

find equations of the tangent line and of the normal line to the curve at the point . write the equations of the lines in the form .

Answers

The equations of the lines in the form y=mx+b are-

Tangent line: y = 240x - 215994Normal line: y = - 0.00417x + 9.75What is slope?

A line's slope is described like the change in y coordinate to the change in x coordinate. The net y coordinate change is y, whereas the net x coordinate change is x.

Therefore the variation in y coordinate in relation to the variation in x coordinate is written as, dy/dx.

Now, as per the given conditions;

The equation of the line is y = (6 + 4x)²

Simplifying the equation;

y = (6 + 4x)²

  = 36 + 48x + 16x²

y = 16x² + 48x + 36

Now, differentiate the equation to find the tangent slope;

dy/dx = 32x + 48

At the point (6,900),

dy/dx = 32(6) + 48 = 240

Let equation of the tangent at point (a,b) is;

(y - b) = m(x - a)

a = 6, b = 900, m = 240

y - 6 = 240(x - 900)

Write this in y = mx + b form,

y - 6 = 240x - 216000

y = 240x - 215994 (Equation of Tangent line)

The slope of the normal line = -(1/slope of the tangent line) (since they're both perpendicular to each other)

Slope of the normal line = -1/240

The, equation of the normal will become;

y - 6 = (-1/240)(x - 900)

y - 6 = (-x/240) + 3.75

y = (-1/240)x + 9.75

y = - 0.00417x + 9.75 (Equation of Normal line)

Thus, the equation for the normal and tangent has be found.

Find the equation of the line that is parallel to y=-2/3x and contains the point (4,-8)

Answers

Answer:

Step-by-step explanation:

Any line parallel to y = (-2/3)x has the same slope:  (-2/3).

Then, in this pattern, y = (-2/3)x + c, where c is the y-intercept.

If (4, -8) lives on this new line, then:

-8 = (-2/3)(4) + c, and

-8 = -8/3 + c

This last equation is equivalent to -24/3 + 8/3 + c  => -16/3 = -c.

Additional comment

As you can see here, there is no real reason to find the value of x, then substitute it back into the expression for the segment of interest. We can, and did, solve directly for the value of that expression.

As with any algebraic manipulation, any operation performed on one side of the equal sign must also be performed on the other side of the equal sign. When we say "subtract ()", we mean "subtract () from both sides of the equation."

In problem 11, x=-9. In problem 12, x=-8. Negative values of x work just fine, as long as the resulting segment lengths are positive.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Given two points on the graph, the slope is given by change in y divided by change in x. For this problem, the points are given as follows:

(0, 440) and (40,0).

Hence the slope is:

m = (0 - 440)/(40 - 0) = -11.

Meaning that in each minute, he descended 8 meters. Thus the time to descend 88 meters is given by:

The volume of the square frustrum is 1018791.667 cubic feet, the volume of the pyramid is 22019.625 cubic feet and the volume of the Washington Monument is 1040811.292 cubic feet.

What is the volume of the Washington Monument?

The Washington Monument is an obelisc and the volume of the obelisc is the sum of the volumes of the square frustrum and the pyramid, that is:

V = V' + V''                                             (1)

V' = (1 / 3) · (a² + a · b + b²) · h              (2)

V'' = (1 / 3) · b² · h'                                 (3)

Where:

V' - Volume of the square frustrum, in cubic feet.V'' - Volume of the pyramid, in cubic feet.a - Length of the side of the lower base, in feet.b - Length of the side of the upper base, in feet. h - Height of the square frustrum, in feet.h' - Height of the pyramid, in feet.

If we know that a = 55 ft, b = 34.5 ft, h = 500 ft and h' = 55.5 ft, then the volume of the Washington monumement is:

V' = (1 / 3) · (55² + 55 · 34.5 + 34.5²) · 500

V' = 1018791.667 ft³

V'' = (1 / 3) · 34.5² · 55.5

V'' = 22019.625 ft³

V = 1040811.292 ft³
