Step-by-step explanation:

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]

Answer:

5.5

Step-by-step explanation:

B is the midpoint of AC, D is the midpoint of CE

This means that CE = 1/2 AE

CD = 1/2 ( 11)

CD = 5.5

[tex]\boxed{162}[/tex] can be a perfect square if the factor [tex]\boxed{2}[/tex] is a paired.

Hence,[tex]\boxed{162×2}[/tex],will be a perfect square.

[tex]: \implies{324 = {3}^{2} \times {3}^{2} \times {2}^{2} }[/tex]

Hence,the square root is [tex]3×3×2,i.e. 18[/tex]

[tex]{\rm{162 \: must \: be \: multiplied \: by \: 2 \: to \: make \: it \: a \: perfect \: square.}}[/tex]

Answer:

2

Step-by-step explanation:

[tex]\\ \rm\Rrightarrow \sqrt{162}[/tex]

[tex]\\ \rm\Rrightarrow \sqrt{2\times 3\times 3\times 3\times 3}[/tex]

Now there is one 2 left .

We need another 2

So we get

[tex]\\ \rm\Rrightarrow 2(3)(3)[/tex]

Answer:

  7.50

Step-by-step explanation:

To evaluate an expression for particular values of the variables, put those variable values in place of the corresponding variable and evaluate the resulting numerical expression according to the Order of Operations.

  [tex]2x^2 +\dfrac{y^2}{3}\qquad\text{for x=1.5 and y=3}\\\\=2(1.5)^2+\dfrac{3^2}{3}\\\\=2(2.25)+\dfrac{9}{3}=4.50+3=\boxed{7.50}[/tex]

I would say that statistics is a mathematical subject that allows you to explain scientific data. In a similar fashion, you could use mathematics to explain the various idea in physics as you can use statistics to interpret the results of experiments and the data collected.

Hope that helped!

Have a good day!

Answer:

3 pounds.

Step-by-step explanation:

I also want to say you know what's funny Raj is my initials my name is Rileigh andrew johnson. But anyway 3 pounds.

Because times 3 by 5=15 so our fraction is now 15/5

And now wil times 5 tintil we get to 15 for our whole number so 5 x 3 =15 so 3 is our whole number/ our answer 3 pounds.

I hope this helps have a awesome day  

Answer:

41

Step-by-step explanation:

a^2 + b ^2 =c^2

9^2 + 40^2 = c^2

81+ 1600 = c^2

1681= c^2

[tex]\sqrt{1681[/tex] = [tex]\sqrt{c^{2}[/tex]

41 = c

Answer:

6 hours.

Step-by-step explanation:

A day is 24 hours. So in this case, 3 quarters of a day will be 18 hours, half a day is 12 hours, and a quarter of a day will be 6 hours.

Answer:

6 hours

Step-by-step explanation:

1/4=6h

2/4=12h

3/4=18h

4/4=24h

Answer:

Unclear.

To find the perimeter you need all three sides of the triangle. You have only given two.

All you need to do is add up all three sides and you have your perimeter.

Formula: P=a+b+c

Answer:

Unknown unless you give the amount of cm for the last side

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:

A) At least 1 Right angle

Step-by-step explanation:

As you can seel all the shapes here have atleast 1 right angle, but all the shapes don't have all the things that the other answer choices are saying.

So hence, your answer is A) At least 1 Right Angle

Thanks!

Answer:

80

Step-by-step explanation:

After spending some time arranging the numbers in order, we get the sequential order as 8, 11, 23, 32, 34, 58, 58, 66, 83, 88.

Next, we need to find the range. The Range of a data set is the difference between the largest and smallest number.

Answer:

C (14 aq units)

Step-by-step explanation:

Area of a triangle = 1/2 x base x height

Base = MY = 4 UNITS

Height = AM = 7 UNITS

Area = 4 x 7 x 1/2 = 14

Answer:

Area=1/2×base×height

But base=4 units and height=7 units

So the area is

1/2×4×7

which is 14 sq units
