Answer:

Step-by-step explanation:

Take the last number in the fraction ( the denominator ) and make a segment that long. Than, take the first number in the fraction ( the numerator ) and highlight, bolden, color, or do whatever needs to be done to make sure that the numerator's value stand out.

The formula of an area of a circle:

$A_O=\pi r^2$

We have

r = 1.8 m

π ≈ 3.14

Substitute:

$A_O=\pi\cdot1.8^2=3.24\pi\ m^2\approx3.24\cdot3.14=10.1736\ m^2\approx10.17\ m^2$

What is the slope of the line that contains the points (-4,2) and (6,-3)?-

schepotkina [342]

Answer:

Step-by-step explanation:

the formula is $\frac{y_{2}-y_{1} }{x_{2} -x_{1}}$

When we plug that in we get $\frac{-3-2}{6- (-4)} = \frac{-5}{10} = -\frac{1}{2}$

Hope this helps!

What is the answer to this question I am really having trouble ??

<h3>Answer: Choice B</h3><h3>y = x^2 + 7x + 1</h3>

======================================

Proof:

A quick way to confirm that choice B is the only answer is to eliminate the other non-answers.

If you plugged x = 1 into the equation for choice A, you would get

y = -x^2 + 7x + 1

y = -1^2 + 7(1) + 1

y = -1 + 7 + 1

y = 7

We get a result of 7, but we want 9 to be the actual output. So choice A is out.

-----------

Repeat for choice C. Plug in x = 1

y = x^2 - 7x + 1

y = 1^2 - 7(1) + 1

y = 1 - 7 + 1

y = -5

We can eliminate choice C (since again we want a result of y = 9)

-----------

Finally let's check choice D

y = x^2 - 7x - 1

y = 1^2 - 7(1) - 1

y = 1 - 7 - 1

y= -7

so choice D is off the list as well

-----------

The only thing left is choice B, so it must be the answer. It turns out that plugging x = 1 into this equation leads to y = 9 as shown below

y = x^2 + 7x + 1

y = 1^2 + 7(1) + 1

y = 1 + 7 + 1

y = 9

And the same applies to any other x value in the table (eg: plugging in x = 3 leads to y = 31, etc etc).
