Answer:
Done
Step-by-step explanation:
Ok
Cube has 6 faces/planes :)
Answer:
4 batches:
cups
7 batches:
cups
Step-by-step explanation:
If he uses 2/3 cup of flour for <u>each</u> batch, then that is 2/3 four times, or 2/3 · 4.
× ![\frac{4}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B1%7D)
=
= ![2\frac{2}{3}](https://tex.z-dn.net/?f=2%5Cfrac%7B2%7D%7B3%7D)
If he makes three more, than that will be 7 batches in total. We can multiply 2/3 by 3 to find out how much will be needed for those extra three, then add that product to
.
× ![\frac{3}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B1%7D)
=
= 2
= ![4\frac{2}{3}](https://tex.z-dn.net/?f=4%5Cfrac%7B2%7D%7B3%7D)
Thus,
and
are the answers.
hope this helps!
Answer:
Standard Form: y = 4(x-1)(x+5)
Step-by-step explanation:
4 is the leading coefficient, so it should go in front. When making a standard quadratic equation, you must do the opposite for each of the roots (negative to positive, positive to negative.)
if you’re asking for a general form quadratic equation, then sorry, I am unable to help you with that :(
For any circle with Cartesian equation
![(x-a)^2 + (y-b)^2 = r^2](https://tex.z-dn.net/?f=%28x-a%29%5E2%20%2B%20%28y-b%29%5E2%20%3D%20r%5E2)
,
we have that the centre of the circle is
![(a,b)](https://tex.z-dn.net/?f=%28a%2Cb%29)
, and the radius of the circle is
![r](https://tex.z-dn.net/?f=r)
.
So in the case that
![(x-5)^2 + y^2 = 38](https://tex.z-dn.net/?f=%28x-5%29%5E2%20%2B%20y%5E2%20%3D%2038)
,
we essentially have that
![a = 5, b = 0, r^2 = 38](https://tex.z-dn.net/?f=a%20%3D%205%2C%20b%20%3D%200%2C%20r%5E2%20%3D%2038)
.
So the centre of the circle is
![(5,0)](https://tex.z-dn.net/?f=%285%2C0%29)
, and the radius is
![\sqrt{38}](https://tex.z-dn.net/?f=%5Csqrt%7B38%7D)
.
