Answer:

Solution,

0.02×100=2

I think it will help you.

The product 0.02 x 100 = 0.02 x 10² =2

A number system is defined as a system of writing to express numbers.

The given is 0.02 x 100

We need to find the product of zero point zero two times of hundred.

This we can do by using the operation multiplication.

Multiplication is a method of finding the product of two or more numbers

We know that 100 we can write in the form of 10²

When 0.02 is multiplied with 10² we get 2

Hence, the product 0.02 x 100 = 0.02 x 10² =2

Answer:

32^3

Step-by-step explanation:

You are multiplying 32 3 times.

Step-by-step explanation:

Since the ball is going upwards, then down, we have a parabola.

In the form of

[tex] - {x}^{2} + bx + c = 0[/tex]

The leading coeffeicent is negative because we are increasing then decreasing.

Let use t for seconds and h is height.

So we have a function

[tex]h(t) = - {t}^{2} + b(t) + c[/tex]

Since I'm have no information: I'm use calculus and physics to solve this.

All objects fall at the speed of

[tex] - 9.8 \frac{m}{ {s}^{2} } [/tex]

Which is the unit for acclereation.

Since we have are trying to a poisition versus time function, note that the anti derivative of acclereation will give us velocity. So let calculate that

[tex] \frac{d}{dx} (a) = - 9.8x[/tex]

Then note that the anti derivative of velocity is poistion.

[tex] \frac{d}{dx} (v) = - 4.9 {x}^{2} [/tex]

So we know our leading coeffeicent, is -4.9x^2.

The ball is initially launched at a speed of 15 m/s. So the first derivative of the function at x=0, should be 15.

[tex] \frac{d}{dx} (x) = - 4.9 {x}^{2} + bx[/tex]

[tex]v = - 9.8x + b[/tex]

Since 0 times anything is 0, b must be 15 in order to have a first derivative of 15.

Since 0,1 is the y intercept, c will be 1.

So our answer is

[tex] - 4.9 {x}^{2} + 15x + 1 = 0[/tex]

b). When x=1, we get a height of 11.1. Plug in 1 into the function, and we get 11.1

c). Set the function equal to zero and use quadratic formula to solve. You will get 3.13 seconds.

d. The max occurs when the velocity is 0. So we can first differentiate the function, which we will get

[tex] - 9.8x + 15 = 0[/tex]

Then we solve for x.

We get 1.5 seconds. Then plug in 1.5 into the function, we get 12.5. So the max height is 12.5 and this occurs at 1.5 seconds.

e).

Answer:

7.50 (nearest hundredth)

Step-by-step explanation:

General form of geometric progression:  [tex]a_n=ar^{n-1}[/tex]

(where [tex]a[/tex] is the initial term and [tex]r[/tex] is the common ratio)

Given progression:

[tex]5\left(\dfrac13\right)^{n-1}[/tex]

Therefore:

Sum of a geometric series:

[tex]S_n=\dfrac{a(1-r^n)}{(1-r)}[/tex]

Substituting a = 5, r = 1/3 and n = 10 to find the sum to n = 10:

[tex]\implies S_{10}=\dfrac{5(1-\frac13^{10})}{(1-\frac13)}[/tex]

[tex]\implies S_{10}=7.499873987...[/tex]

[tex]\implies S_{10}=7.50 \textsf{ (nearest hundredth)}[/tex]

Based on the sum and the share value after the relevant number of years, Charlotte's share is $4,137.46 and Ali's share is $3,752.54.

This can be solved using the substitution method:

Alice share + Charlotte's share = 7,890

As + Cs = 7,890

As = Cs

(As x Future value factor, 5%, 8 years) = (Cs x Future value factor, 5%, 6 years)

(As x 1.47745) = (Cs x 1.3400)

Cs = (As x 1.47745) / 1.3400

Cs = As x 1.1025746

Slotting these back in the original formula gives:

As + (As x 1.1025746) = 7,890

2.1025746As = 7,890

,As = 7,890 / 2.1025746

= $3,752.54

Charlotte's share will be:

= 7,890 - 3,752.54

= $4,137.46
