A circles radius is 13 meters what is the circles area using 3.14 rounded to the nearest tenth

Answers

Answer 1

Answer:

530.7

Step-by-step explanation:

A circle's area is defined as πr²

You would substitute 13 in for r (the radius) and use 3.14 as your given value for pi, leaving you with this:

3.14×13²

When you calculate this, it should return a value of 530.66, which rounded to the nearest tenth is 530.7

-
3

Answers

Answer:

(0,-4)

Step-by-step explanation:

Given

[tex]f(x) = x^\frac{1}{3} - 4[/tex]

Required

Determine the critical numbers

[tex]f(x) = x^\frac{1}{3} - 4[/tex]

Differentiate:

[tex]f'(x) = \frac{1}{3}x^{\frac{1}{3} - 1}[/tex]

[tex]f'(x) = \frac{1}{3}x^{-\frac{2}{3}}[/tex]

Equate to 0

[tex]f'(x) = \frac{1}{3}x^{-\frac{2}{3}} = 0[/tex]

[tex]\frac{1}{3}x^{-\frac{2}{3}} = 0[/tex]

Multiply through by 3

[tex]3 * \frac{1}{3}x^{-\frac{2}{3}} = 0*3[/tex]

[tex]x^{-\frac{2}{3}} = 0[/tex]

[tex]x = 0[/tex]

Substitute 0 for x in [tex]f(x) = x^\frac{1}{3} - 4[/tex]

[tex]f(0) = 0^\frac{1}{3} - 4[/tex]

[tex]f(0) = 0- 4[/tex]

[tex]f(0) = - 4[/tex]

Hence, the critical point is: (0,-4)

If 6(2x+1) is equal to -36-2x, what is the value of 3x

Answers

6(2x + 1) = -36 - 2x
12x + 6 = -36 - 2x
12x + 2x = -36-6
14x = -42
X = -3

Answer:

The value of 3x is -9

Step-by-step explanation:

Given Equation

[tex]6(2x + 1) = - 36 - 2x[/tex]

Step 1

Distribute 6 in the expression.

[tex]12x + 6 = - 36 - 2x[/tex]

Step 2

Combine like terms and solve the equation for x-term

[tex]12x + 2x = - 36 - 6 \\ 14x= - 42 \\ x = \frac{ - 42}{14} \longrightarrow \frac{ - 3}{1} \\ x = - 3[/tex]

But we want to know what is the value of 3x.

Step 3

Substitute the value of -3 in 3x.

[tex]3x = 3( - 3) \\ 3x = - 9[/tex]

Hence, the value of 3x is -9

A new secretary has been given n computer passwords, only one of which will permit access to a computer file. Because the secretary has no idea which password is correct, he chooses one of the passwords at random and tries it. If the password is incorrect, he discards it and randomly selects another password from among those remaining, proceeding in this manner until he finds the correct password. What is the probability that he obtains the correct password on the second try? The third try?

Answers

Answer:

The answer is "[tex]\bold{\frac{1}{n}}[/tex]"

Step-by-step explanation:

Although n passwords were available and any time a wrong password is deactivated. Throughout the second try, if the secretary finds the right password, its input during the first attempt should be incorrect. Therefore, the likelihood is:

[tex]\to Pr= \frac{n-1}{n} \times \frac{1}{n-1} =\frac{1}{n}[/tex]

If n passwords were accessible and any time the wrong password is deactivated. Unless the delegate finds the right password on the three trials, the input should be incorrect during the first and second trials. Consequently, the likelihood is:

[tex]\to Pr= \frac{n-1}{n} \times \frac{n-2}{n-1} \times \frac{1}{n-2} =\frac{1}{n}[/tex]

2.1n -5.31 = 18
Question : Find n
Pls Answer !!

Answers

Answer:

n = 11.1

Step-by-step explanation:

2.1n = 18 + 5.31

2.1n = 23.31

n = 23.31 / 2.1

n = 11.1

Hope that helps!!!!

2.1n-5.31=18
+5.31=+5.31
2.1n= 23.31
23.31/2.1 = 11.1
n=11.1

To check answer plug 11.1 in to the spot of n & multiply it by 2.1 then subtract from 5.31 and you should get 18 .

the measure of ZF?

Answers

Answer:

63° is the answer according to me

The value of measure of angle F is,

⇒ ∠ F = 63°

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

Triangle ABC and DEF are congruent.

Hence, Their corresponding angles are same.

So, We get;

⇒ ∠ A = ∠X

⇒ ∠B = ∠Y

⇒ ∠C = ∠Z

Here, ∠C = 63°

Hence, The value of measure of angle F is,

⇒ ∠ F = 63°

Thus, The value of measure of angle F is,

⇒ ∠ F = 63°
