Find an equation of the plane that is parallel to the xz-plane and is located 25 units to the left of the xz-plane in standard perspective.

Answer:

............... 3 6/8

Answer: [tex]f(x)=-x[/tex]

Step-by-step explanation:

When f(-x)= -f(x), then it is known as an odd function.

i) [tex]f(x) = x^3 + 5x^2 + x[/tex]

Then, [tex]f(-x)=(-x)^3+5(-x)^2+(-x)=-x^3+5x^2-x\neq -x^3-5x^2-x[/tex]

i.e. [tex]f(-x)\neq-f(x)[/tex]

ii) [tex]f(x)=\sqrt{x}[/tex]

[tex]f(-x)=\sqrt{-x}\neq-\sqrt{x}[/tex]

i.e. [tex]f(-x)\neq-f(x)[/tex]

iii) [tex]f(x)=x^2+x[/tex]

[tex]f(-x)=(-x)^2+(-x)=x^2-x\neq-x^2-x[/tex]

i.e. [tex]f(-x)\neq-f(x)[/tex]

iv) [tex]f(x)=-x[/tex]

[tex]f(-x)=-(-x)=x[/tex]

[tex]-f(x)=-(-x)=x[/tex]

i.e. [tex]f(-x)=-f(x)[/tex]

Hence, f(x) is an odd function.

Hey there!

Well first, don't feel bad, since trig is really hard, especially if you are just learning it.

If you've learned about SOH CAH TOA, you will see that TOA is the best identity to use here.

Answer:

15% above the trend.

Step-by-step explanation:

A time series represented by Y comprises of dataset observed over a particular period of time. Time series is handy in determining the future of a particular business.

In a multiplicative model, if the seasonal factor is 1.15 for a particular season, then we expect that the time series in that season would be

Y = T × C × S × 1

where;

Seasonal S = 1.15

As such Y would increase by 15% above the trend if all other things are being equal.

Answer: b) 6.10%

Step-by-step explanation:

to find the probability for the other bag to contain exactly 4 balls at that time;  

is only possible if you have chosen a particular bag 10 times and other bag 6 times.

After that, once again at the 17th attempt

so the required probability =     ¹⁶c₁₀ × (1/2¹⁰ × (1/2)⁶ × (1/2)

= 0.610

CONVERT TO PERCENT

0.610 × 100

= 6.10%

Answer:

(0,-4) (5,0)

Step-by-step explanation:

4x-5y=20

First, we must put the equation into slope intercept form: y= mx+b

5y=4x-20=y=4/5x-4

The y intercept, by definition, is b. In this scenario, b is -4.

One ordered pair that works is (0,-4).

Also, we can find the ordered pair for the x intercept. By definition, the x intercept is the value of x when y equals zero. hence, we substitute 0 for y and then we can find an ordered pair that works and solve for x!:

Therefore, (5,0) works as well!

Answer: (a). 0.2% (b). 0.4%

Step-by-step explanation:

This is quite straightforward, so let us follow this carefully.

(a) let us consider the expression that was given in the question;

(8.47 + 0.06)1/3 from the binomial expression,

⇒  (x + ∆x)n = xn + nxn-1∆x

So using the stated formula above

(8.47 + 0.06)1/3 = (8.47)1/3+ 1/3(8.47)1-(1/3) (0.06) = 2.038 + 1/3(8.47)(2/3) (0.06)

= 2.038 + 0.005

This gives us the algebric value as x = 2.038

Also, the uncertainity is ∆x = 0.005

Let us calculate the percentage of relative uncertainity;

Relative uncertainity percent is given thus;

⇒ (∆x / x) * 100

= (0.005 / 2.038) * 100 = 0.2%

We have that the relative uncertainity percent is 0.2%

(b). Also we will consider the expression;

log(6.56 + 0.05)

Let us apply the binomial expression to this;

log(6.56 + 0.05) = log(6.56) + ((0.05)2 / 6.56) = 0.817 + 0.003

This makes the algebric value of x = 0.817

and the uncertainity is  ∆x = 0.003

Therefore the Relative uncertainity percent is = (∆x / x) * 100

= (0.003 / 0.817) * 100 = 0.4%

We have the relative uncertainity percent as 0.4%

Answer: ( -0.731,  0.682)

Step-by-step explanation:

The unit vector is defined as a vector that points in the same direction as our vector (137 degrees from the x-axis) and has a magnitude of 1.

Knowing the angle, is really simple to do it.

First, we know that for a radius R and an angle A, the rectangular coordinates can be written as:

x = R*cos(A)

y = R*sin(A)

And if we want that the magnitude/modulus of our vector to be 1, then R = 1, and we know that A = 137°

x = 1*cos(137°) = -0.731

y = 1*sin(137°) = 0.682

Then the unit vector is: ( -0.731,  0.682)

The unit vector is ( -0.731,  0.682)

[tex]x = R\times cos(A)\\\\y = R\times sin(A)[/tex]

And the magnitude/modulus of our vector to be 1, then R = 1, and we know that A = 137°

so,  

[tex]x = 1\times cos(137) = -0.731y = 1\times sin(137) = 0.682[/tex]

Then the unit vector is: ( -0.731,  0.682)

Step-by-step explanation:

Area of the basket ball court = Length * Breadth (since it is rectangular in nature)

Area of the basket ball court = 94 feet * 50 feet

Area of the basket ball court = 4700ft²

Area of the space covered by 8 kids = 3ft * 3ft = 9ft²

To know the number of kids that would fit the entire floor, we will use the expression;

Number of kids in the floor = 8*Area of the basket ball court /Area of the space covered by 8 kids = 8*4700/9

= 8*4700/9

= 8*522.22

≈ 4,178 kids

Hence approximately 4,178 kids can fit side by side  over the entire floor

Answer:

m = 2

Step-by-step explanation:

Given:

x = 4

y = 6m - 2

a = 8

b = 5

Required:

Value of m

SOLUTION:

x and y are segments of a chord divided when it intersects another chord that also has segments a and b.

According to the Intersecting chords theorem, [tex] a*b = x*y [/tex]

Thus:

[tex] 8*5 = 4*(6m - 2) [/tex]

Solve for m

[tex] 40 = 24m - 8 [/tex]

[tex] 40 + 8 = 24m - 8 + 8 [/tex]

[tex] 48 = 24m [/tex]

[tex] \frac{48}{24} = \frac{24m}{24} [/tex]

[tex] 2 = m [/tex]

Answer:

Approximately 2 days.

Step-by-step explanation:

The frog can only jump 3 lily pads each day.

24 hours = 1 day

[tex]\frac{24}{3}[/tex] = 8 hours

Thus, it would take the frog 8 hours to cover a lily pad.

To get to the edge of the pond, the frog would jump through 6.5 lily pads (since he is at the middle of a lily pad at the center of the pond).

So that;

Total time required to get to the edge of the pond can be determined by;

6.5 × 8 hours = 52 hours

Number of days to get to the edge of the pond = [tex]\frac{52}{24}[/tex]

                                                                    = 2.2

It would take him approximately 2 days to get to the edge of the pond.
