The answer is in point-slope formula. You have to take the two intercepts and get the slope. The slope would be 3. Then the point-slope formula is (y-y1)=m(x-x1). They have (y+?)=?(x+1). You have to look at the points that are given and plug them in the equation.
So, the final answer would be (y+2)=3(x+1).

a water sprinkler sends water out in in a circle .how large is the watered area if the the watering Patten is 23 ft

Dennis_Churaev [7]

I'm guessing you're saying that the sprinkler is shooting out 23 ft of water.

This would be the same as the radius of a circle, and we're trying to find the area. Use the formula.

$\sf A=\pi r^2$

Plug in what we know:

$\sf A=\pi (23^2)$

$\sf A=529\pi ft^2$

This is what they could be looking for, an exact value. If they want an approximation, we can input 3.14 for Pi:

$\sf A\approx 529(3.14)$

$\boxed{\sf A\approx 1661.06~ft^2}$

Answer:

Well according to the number line shown, it is in the negative area and if you see this it is near -6.5, all you need to do is count the spots until it hits the circle which is -6.8

Consider the following graph of two functions,S(1) + 8(2)Step 1 of 2: Finds (1) + 8(2)Enable Zoom/Pan8(x) = x2 - 2x - 1S(x) = -x

kumpel [21]

.Given:

$\begin{gathered} f(x)=-x+1 \\ g(x)=x^2-2x-1 \end{gathered}$

ToDetermine: The value of

$f(1)+g(2)$

Solution

$\begin{gathered} f(x)=-x+1 \\ f(1)=-1+1 \\ f(1)=0 \end{gathered}$ $\begin{gathered} g(x)=x^2-2x-1 \\ g(2)=(2)^2-2(2)-1 \\ g(2)=4-4-1 \\ g(2)=-1 \\ f(1)+g(2)=0+(-1) \\ f(1)+g(2)=-1 \end{gathered}$

Hence, f(1) + g(2) = -1
