solve for r
A= 3r(to the 2 power) i couldn’t make it a small two

Solve For R A= 3r(to The 2 Power) I Couldnt Make It A Small Two

Answers

Answer 1

Answer:

r = [tex]\sqrt{\frac{a}{3}}[/tex]

Step-by-step explanation:

1. A = 3r²

(Divide 3 by both sides)

2. A/3 = r²

(Square root both sides)

√A/3 = r

Answer 2

On solving for 'r' we get -  r = [tex]\sqrt{\frac{A}{3} }[/tex].

We have the following expression -

[tex]$A=3r^{2}[/tex]

We have to solve for r.

Solve for x :  [tex]$x^{2} = 9[/tex]

On solving, we get -

x = [tex]$\pm\sqrt{9}[/tex]

x = [tex]$\pm3[/tex]

According to the question, we have -

[tex]$A=3r^{2}[/tex]

[tex]$r^{2} = \frac{A}{3}[/tex]

r = [tex]\pm\sqrt{\frac{A}{3} }[/tex]

Since, the area cannot be negative, therefore -

r = [tex]\sqrt{\frac{A}{3} }[/tex]

Hence, on solving for 'r' we get -  r = [tex]\sqrt{\frac{A}{3} }[/tex].

Determine the largest positive integer N such that 1005! is divisible by 10N.

Answers

9514 1404 393

Answer:

  N = 250

Step-by-step explanation:

The way your question is written, the answer is a number of 2582 digits, much too large to show here. We assume you actually want N such that 10^N is the largest power of 10 that will divide 1005!.

__

That factor is limited by the number of factors of 2 and 5 in 1005!. Of those, there are far more factors of 2, so the actual limit is the number of factors of 5 in 1005!.

Every 5th number is divisible by 5, so there are 1005/5 = 201 numbers divisible by 5 in 1005!.

Every 5th one of those is divisible by another factor of 5, so an additional 201/5 ≈ 40.

Every 5th one of those is divisible by another factor of 5, so an additional 40/5 = 8.

Finally, every 5th one of those has yet another factor of 5, so an additional 8/5 ≈ 1.

Then the total number of factors of 5 in 1005! is 201 +40 +8 + 1 = 250.

That is, the number 1005! will end in 250 zeros. It will be divisible by 10^250.

  N = 250

Step-by-step explanation:

Before we answer, the area of a Circle given it radius is

[tex]a = \pi r {}^{2} [/tex]

The area of a circle given it diameter is

[tex]a = \pi( \frac{d}{2} ) {}^{2} [/tex]

So let answers question 1-4.

1. The area is

[tex]1024\pi[/tex]

2. The area is

[tex]576\pi[/tex]

3.

[tex]1.225\pi[/tex]

4.

For the 5th problem, circumference is

[tex]\pi \times d[/tex]

where d is the diameter and

[tex]2\pi r[/tex]

where r is the radius.

A circumference of 100 m means the radius is 50 because

Let ABC be an isosceles triangle at A. Take point D on side AC, point E on side AB such that AD = AE a) Compare the angles ABD and ACE b) Let I be the intersection of BD and CE. What kind of triangle is ΔIBC? Why ?

Answers

9514 1404 393

Answer:

  a) they are congruent

  b) isosceles; ∠IBC≅∠ICB

Step-by-step explanation:

a) We are given that ΔABC is isosceles, such that AB≅AC. Points D and E are located so that AD≅AE. Of course, ∠A≅∠A, so ΔACE ≅ ΔABD by SAS. Then angles ABD and ACE are congruent by CPCTC.

__

b) Angle IBC is the difference between angle ABC and angle ABD. Angle ICB is the difference between angle ACB and angle ACE. These differences are between values that are the same, so the differences are the same. That means ∠IBC≅∠ICB, and ΔIBC is isosceles.

one can of cat food.
A $0.65
B $0.60
C $0.30
D$0.70

Answers

Answer:

B: $0.60

Step-by-step explanation:

4x+6=8.40

Answer:$0.60

Step-by-step explanation:

A bag a kibble is 6$

Subtract the cost for the kibble to the cost of all products.

  $8.40

-  $6.00  

  $2.40...  is the cost for all 4 cans of cat food.

Then divide $2.40 by 4... That will be B) $0.60

There are few kind of statistics: first of all - Mathematiсal statistics. This is quite a mathematical science.

Its applications widely used in many branches of science. First of all (for me) in measurement theory. When used correctly, there is no objection to this science and its methods.

The use in the so-called "social sciences", primarily in sociology, raises many questions: first and foremost - how representative is the "sample"? To what extent does the question asked by the respondent dictate the “correct” (expected) answer? And so on. Of course, this is not a statistic, but mostly a science-like hype, covering up the absence of objective methods.

If all the exponents are even, then the polynomial function is even.

Choice A has a mix of even and odd exponents here, so choice A is neither even nor odd. We can rule this out.Choice B is the same story as choice A. So we can rule that out as well.Choice C has all of its exponents even. Therefore function C is an even function, and it's the final answer.Choice D is the same story as choice A.

Answers

Answer:

h = 3 sqrt(21)

or

h = 13.75

Step-by-step explanation:

The perimeter of the rhombus is 60 feet. Like a square, all the sides of a rhombus are equal. Therefore your first step is to find FK which is a side.

FK = 60/4 = 15 feet.

Now you can use the Pythagorean Theorem.

a^2 + b^2 = c^2

a = 6

b = height or = h

c = 15

6^2 + b^2 = 15^2

36 + b^2 = 225

b^2 = 225 - 36

b^2 = 189

sqrt(b^2)= sqrt(189)

b = sqrt(3 * 3 * 3 * 7)  You can take out the square of 3 * 3 and make it 3.

b = 3 * sqrt(3*7)

b = 3 * sqrt(21)

The total cost of a desk and a stool is $86.50.
The stool costs $25.50 less than the desk.
How much does the stool cost?

Answers

Answer:

$30

Step-by-step explanation:

d + s= 86.50----------1

d - 25.50 = s

d - s=25.50------------2

1 - 2

(d-d) +(s-(-s))=86.50-25.50

2s=60

s=60/2=$30

The cost of a stool is $30.5 if the total cost of a desk and a stool is $86.50 and the stool costs $25.50 less than the desk.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The total cost of a desk and a stool is $86.50.

The stool costs $25.50 less than the desk.

Let the cost of the desk is $d

Let the cost of the stool is $s

d + s = 86.50
s = d - 25.50

The above two equations represent two linear equations in two variables.

By solving by substitution method:

Plug s = d - 25.50 in the first equation

d + d - 25.50 = 86.50

2d = 86.50 + 25.50

2d = 112

d = 112/2

d = $56

s = 86.50 - 56

s = $30.5

Thus, the cost of a stool is $30.5 if the total cost of a desk and a stool is $86.50 and the stool costs $25.50 less than the desk.
