Answer:

Step-by-step explanation:

Circumference = 2×pi×radius

6pi=2×pi×radius

6pi/pi=2radius

2radius=6

Since 2radius=diameter

Therefore diameter=6 units

Which equation is the inverse of y = 7x2 – 10?

MrRissso [65]

we have

$y=7x^{2}-10$

To find the inverse

Step 1

Exchanges the variables, x for y and y for x

$x=7y^{2}-10$

Step 2

Isolate the variable y

$x=7y^{2}-10$

$7y^{2}=x+10$

$y^{2}= \frac{x+10}{7}$

Square Root both sides

$y=(+/-)\sqrt{\frac{x+10}{7}}$

Step 3

Let

$f(x)^{-1}=y$

$f(x)^{-1}=(+/-)\sqrt{\frac{x+10}{7}}$

therefore

<u>the answer is</u>

The inverse is

$f(x)^{-1}=(+/-)\sqrt{\frac{x+10}{7}}$

I have no idea how to do this! Can somebody please help me out a little?

Two equivalent forms:

x1, y2

Explain: x1 creates the shape of the polynomial and y1 sharpens it, to make it look more realistic and more rounded.

This is the last one for the morning and may be some later

kompoz [17]

Answer:

A is correct Please brainliest me

Thus, also saying that it is equivalent.

Step-by-step explanation:

The expression stated- (3m+1-m)

It also states to give a equal amount

What is equalevent expression?- Equivalent expression are those expression that looks different but are same.

For example, 2+2 is 4 and 1 plus 3 is 4

it is different expression but the same answer.

The Expression- 3m+1-m

Simplify. How?- By adding LIKE terms.

Here- 3m+ 1 - m = (3-1) m + 1

see the same.

To conclude, 3-1) m + 1 = 2m + 1

If you’d wanna write in another way, it would be 2m + 1 can be written as m + m + 2 - 1

so a is correct

Please help it’s the last question

Mrac [35]

Answer:

$y=$ $-\frac{5}{6}x - 1$ is the answer

Step-by-step explanation:

Equation of the line: y = 6/5x + 1

= 5y = 6x + 5

= 6x - 5y + 5

Equation of the perpendicular line: bx - ay + k = 0

= -5x -6y + k = 0

Equation passes through (6,-6),

-5(6) -6(-6) + k = 0

-30 + 36 + k = 0

6 + k = 0

k = -6

Substituting,

-5x -6y + k = 0

-5x -6y -6 = 0

-6y = 5x + 6

$y=$ $-\frac{5}{6}x - 1$ (Slope-Intercept form)
