Answer:

f'(x) = 7

Step-by-step explanation:

This is a basic derivative problem. The first derivative of f(x) would multiply the 7 by the power of x (which is one) and get rid of the 8. So, all you have left is 7 times 1 and your answer would be 7.

Answer:

x=-8/7 or -1.1428

Step-by-step explanation:

The roots (zeros) are the x

values where the graph intersects the x-axis. To find the roots (zeros), replace f(x) with 0 and solve for x

thelma wants to find the equation of a line that passes through the point (2,2) and is perpendicular to the line y=1/2x+5

d1i1m1o1n [39]

<span>perpendicular slope :

m1 * m2 = -1

1/2 * m2 = -1

m2 = -2

y = -2x + b

2 = -4 +b

b = 6

y = -2x + 6

Turn over into vertex form

y=-30t²+450t-790
y=-30(t²-15x+79/3)

Solving

y=-30[(t-15/2)²-359/12]

Open brackets

y=-30(t-15/2)²+1795/2

Accurating

y=-30(t-7.5)²+897..5

Compare to Vertex form y=a(x-h)²+k

Vertex

(h,k)=7.5,897.5

Max profit is $897.5

ticket price should be $7.5
