Answer:

C

Step-by-step explanation:

to find the zeros you look at what value you would fill in for x to make zero, so (x+3) would have a zero of -3 and (x-2) would have a zero of 2

Line j is parallel to line k. Find the m

Rufina [12.5K]

Answer:

- 8.14 = m = slope

Step-by-step explanation:

We know from the diagram that 8x-7 + 5x+18 = 180 so x = 13

so 8x -7 = 97

slope = tan 97 = -8.14

A rope 16 feet long is cut into two pieces. one piece is used to form a circle and the other used to form a square. find a funct

givi [52]

Circumference of Circle=C, =2(pi)(radius)
Radius of Circle=r
Side of square=x
f(x)=area of circle
g(r)=area of square
16 feet=C+4x
C=16-4x
2(pi)(r)=16-4x
2(pi)(r)=2(8-2x)
(pi)(r)=8-2x
r=(8-2x)/(pi)
x=(8-(pi)r)/2
f(x)=(pi)(r^2)
f(x)=(pi)((8-2x)/(pi))^2
f(x)=((8-2x)^2)/(pi)
f(x)=((64-32x+4x^2))/(pi)
g(r)=((8-(pi)r)/2)^2
g(r)=((64-16(pi)r+(pi)^2(r^2))/4

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the

sineoko [7]

Answer:

x = $34.45

Step-by-step explanation:

Solution:-

The company makes a profit of $y by selling widgets at a price of $x. The profit model is represented by a parabola ( quadratic ) equation as follows:

$y = -10x^2 + 689x -6775$

We are to determine the profit maximizing selling price ( x )

From the properties of a parabola equation of the form:

$y = ax^2 + bx + c$

The vertex ( turning point ) or maximum/minimum point is given as:

$x = -\frac{b}{2a} \\\\x = - \frac{689}{2*(-10)} = \frac{689}{20}\\\\x = 34.45$

The profit maximizing selling price of widgets would be x = $34.45.
