Answer:
I dont know, check in calculator
Step-by-step explanation:
So the formula is I=p(1+r)t
6300(1+.08)power of 21
5 1/2 - 3 1/4
5 2/4 - 3 1/4
2 1/4 hours are still required
Just can decorate 2 full cakes. 6 divides by 3 is 2. So she decorated 2 per hour. If you do the work it’s 2 divided by 0.75 (3/4) you get 2 2/3. But that’s not a full 3 cakes so only 2. Glad to help!
S=2(4x+2x)+4x^2=4x^2+12x
4x^2+12x=7
4x^2+12x-7=0
D=12^2-4x4x(-7)=256
X1=(-12-16)/(2x4)=-3.5 impossible
X2=(-12+16)/(2x4)=0.5
A
Step-by-step explanation:
Standard form of a quadratic is f(x) = ax² + bx + c.
To convert to vertex form, the simplest method is to find the x-coordinate of the vertex using h = -b/(2a).
Then, plug back into the equation to find the y-coordinate of the vertex. k = f(h).
Finally, the leading coefficient is the same as the standard form, a.
f(x) = a(x − h)² + k
Another method is to complete the square.
