We have the height h(t) as

h(t) = -16t² + 1024

16t² is how far we've fallen as a function of time; since we started 1024 feet up the height is 1024-16t².

Answer: the distance the brush falls in t seconds, first choice

A boutique handmade umbrella factory currently sells 37500 umbrellas per year at a cost of 7 dollars each. In the previous year

slega [8]

Answer:

$302,500

Step-by-step explanation:

If cost (C) = $7, then Sales (S) = 37,500 units

If cost (C) = $15, then Sales (S) = 17,500 units

The slope of the linear relationship between units sold and cost is:

$m=\frac{37,500-17,500}{7-15}\\m= -2,500$

The linear equation that describes this relationship is:

$s-s_0 =m(c-c_0)\\s-17500 =-2500(c-15)\\s(c)=-2500c + 55,000$

The revenue function is given by:

$R(c) = c*s(c)\\R(c)=-2500c^2 + 55,000c$

The cost at which the derivative of the revenue equals zero is the cost that yields the maximum revenue.

$\frac{d(R(c))}{dc}=0 =-5000c + 55,000\\c=\$11$

The optimal cost is $11, therefore, the maximum revenue is:

$R(11)=-2500*11^2 + 55,000*11\\R(11)=\$ 302,500$

What are the y and x intercepts of y-4=7(x-6)

umka2103 [35]

Answer:

y-intercept= (0,-38)

x-intercept= (38/7,0)

Step-by-step explanation:

y=mx+b

m=slope

b=y-intercept

y-4=7(x-6)

y=7x-38

x-intercept= (38/7,0)

y-intercept= (0,-38)
