Answer:
A = 9, B = 5, C = 3
the parabola opens upwards
y-intercept = 3
Step-by-step explanation:
Since the equation is f(x)=9x^2+5x+3, you can determine what a, b, and c are by associating it with a quadratics standard form, <u>ax^2+bx+c</u>. The numbers correspond with each letter in the skeletal equation.
To determine whether the parabola opens up or down, you can simply look at the a value. If <u>x > 0</u>, the the parabola will <u>open upwards</u>, whereas if <u>x < 0</u>, the parabola will <u>open downwards</u>.
To determine <u>y-intercept</u>, just plug in the value of 0 into x and solve for y.

Answer:
6 complete costumes
Step-by-step explanation:
he has 27/2 total fabric
1 costume requires 1 2/4 + 3/4 of fabric, which is 2 1/4
we divide 27/2 by 9/4
27/2 x 4/9 = 6
Answer:
Step-by-step explanation:
Root:
n≈0.00833333 m + 0.666667
Root for the variable n:
n≈-0.0833333 (-0.1 m - 8)
Derivative:
d/dm(0.1 m + 8 - 12 n) = 0.1
Indefinite integral:
integral(8 + 0.1 m - 12 n) dm = 0.05 m^2 - 12 m n + 8 m + constant
Definite integral over a disk of radius R:
integral integral_(m^2 + n^2<R^2)(0.1 m - 12 n + 8) dm dn = 8 π R^2 + 0
Definite integral over a square of edge length 2 L:
integral_(-L)^L integral_(-L)^L (8 + 0.1 m - 12 n) dn dm = 32 L^2 + 0
