Answer:

When we stand our muscles are working a little bit, and if we're moving around, our muscles are working even more, so we sit down to take a little bit of a break, but the problem starts when we sit down for too long. ... If we sit for too long, it's not good for our heart.

A garden hose emits 9 quarts of water in 6 seconds how much did the water emit in 10seconds

jarptica [38.1K]

Answer:

In 10 seconds, the garden hose will emit 15 quarts of water.

Step-by-step explanation:

The amount of water emitted by the garden hose over time can be expressed as a ratio: 9/6, or 9 quarts of water for every 6 seconds of time. We can then simplify this ratio to 3/2, or 3 quarts of water for every 2 seconds of time. Since the ratio will remain constant, or the same, over time, we can set up an equivalent ratio, or fraction to find the amount of water emitted in 10 seconds: 3/2 = x/10. We look at the denominators and see that 2 x 5 = 10. In order to make the ratios equivalent, we would also multiply the numerator by 5: 3 x 5 = 15, which gives us the amount of water emitted in 10 seconds.

The focus of a parabola is (−5,−1) and the directrix is y=−3.

Bingel [31]

$(x+5)^2=4(y+2)$

the equation for a parabola with focus (h, k+p) and directrix y=k-p is
$(x-h)^2=4p(y-k)$

so using your directrix y=-3, and knowing directrix is y=k-p, you have
-3=k-p.
similarly, knowing the focus is defined by (h,k+p) and your focus is (-5,-1)
you have the equation -1=k+p.

you now have a system of equations
$-3=k-p \\ -1=k+p$
which you can solve using any method, I will use elimination.
adding down
$-4=2k \\ -2=k$
you now have k and can find p using either equation.
$-3=k-p \\ -3=-2-p \\ -1=-p \\ 1=p$ .

now you plug those in, getting the answer
$(x+5)^2=4(y+2)$
