If r is the radius of a circle and d is its diameter, which of the following is an
equivalent formula for the circumference C = 2 pie r?

A. C= pie d
B. C= 2 pie d
C. C=2 pie d^2
D. C = 2 pie rd

Answers

Answer 1

Answer:

A

Step-by-step explanation:

because r is 1/2 of d so you would have 1 d instead of 2 r

Can someone help me with this math problem? “Solve the equation for y, if it’s not already solved for. If already solved for, type already solved.”

the equation: 5x+3y=15

Answers

Answer:

y=(-5/3x)+5

Step-by-step explanation:

so you want to isolate the variable of y.

5x+3y=15

5x+3y-5x=15-5x

3y=-5x+15

3y/3=(-5x+15)/3

y=(-5/3x)+5

Answer: 6[tex]\sqrt{2}[/tex]

Step-by-step explanation: Because the angles are the same, 45 and 45 the other leg of the triangle is also 6.

From there we can use the Pythagorean Theorum to solve for x

6^2+6^2 = 72

so x is [tex]\sqrt{72}[/tex]

which simplifies to 6[tex]\sqrt{2}[/tex]

Answer:

6 rt 2

Step-by-step explanation:

you can use pythagorean theorem (a^2+b^2=c^2)

or since this is a 45, 45, 90 triangle the 2 equivalant sides are equal to each other and the hypotenues is also the legnth of the 2 sides times rt 2

In a unit circle, ø = 2pi radians What is the terminal point?
A. (0,1).
B. (0, -1)
C. (-1,0)
D. (1,0)

Answers

Answer:

The terminal point is (1, 0) D

Step-by-step explanation:

In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis

The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0 or 2π radians and cosФ = 1, sinФ = 0The terminal point on the positive part of the y-axis is (0, 1),which means Ф = [tex]\frac{\pi }{2}[/tex] radians and cosФ = 0, sinФ = 1The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = π radians and cosФ = -1, sinФ = 0The terminal point on the negative part of the y-axis is (0, -1),which means Ф = [tex]\frac{3\pi }{2}[/tex] radians and cosФ = 0, sinФ = -1

In a unit circle

Ф = 2π radians

→ By using the 1st rule above

The terminal point is (1, 0)

Answer:

(1,0)

L=x+1

H=2x-3

So, V= (x-1)(x-1)(2x-3)

Determine any data values that are missing from the table, assuming that the data represent a linear function.

Answers

Answer:

c. 14

Step-by-step explanation:

Let the missing y value be y2.

If the data represent a linear function, then:

[tex] \frac{6 - 2}{2 - 1} = \frac{y_2 - 6}{4 - 2} [/tex]

[tex] \frac{4}{1} = \frac{y_2 - 6}{2} [/tex]

[tex] 4 = \frac{y_2 - 6}{2} [/tex]

Multiply both sides by 2

[tex] 4 \times 2 = \frac{y_2 - 6}{2} \times 2 [/tex]

[tex] 8 = y_2 - 6 [/tex]

Add 6 to both sides

[tex] 8 + 6 = y_2 - 6 + 6 [/tex]

[tex] 14 = y_2 [/tex]

The missing value is 14

Answers

Answer:

  sometimes true

Step-by-step explanation:

The equation reduces to ...

  x^y·x^z = z^18

  x^(y+z) = z^18

This is not true in general, but is true for specific cases of x, y, and z. For example,

  4^(7+2) = 2^18 . . . . (x, y, z) = (4, 7, 2)

  4^(7+0) ≠ 0^18 . . . . (x, y, z) = (4, 7, 0)

The equation is sometimes true.

Javine says, "To multiply by 1000, I just add three zeros." Kian says, "I times by 10, then times by 10 and times by 10 again." Do you agree with Javine and Kian's methods for multiplying by 1000? Explain your thinking.

Answers

Answer:

Kian's method is correct.

Step-by-step explanation:

Javine says, "To multiply by 1000, I just add three zeros." He is incorrect.

Kian says, "I times by 10, then times by 10 and times by 10 again. When he multiply 1 by 10, it becomes 10. Then if he again multiply by 10, it becomes 10×10 = 100. And at last when he multiply again 10, it becomes 100×10 = 1000. It means Kian's methods for multiplying by 1000 is correct.
