In 2001, a company marketed 730,000 units of its product. In 2001 its yearly volume was 50% of its volume for 2004. The 2004 vol
kotykmax [81]

Answer:

4000 units

Step-by-step explanation:

In 2001 the total number of marketed units= 730,000

If this number represents 50% of what was marketed in 2004, then the total number of units marketed in 2004 was:

(100/50)× 730,000=1460000

To get the number for each of the 365 days in 2004 we divide the total for 2004 by 365

1460000/365= 4000 units

The function f(t)=−16t2+88t+12 represents the height (in feet) of a pumpkin t seconds after it is launched from a catapult. when
givi [52]

Answer:

2.75 seconds and 133 feet

Step-by-step explanation:

We require to find the coordinates of the vertex of the parabola

the t coordinate ( time ) for a quadratic in standard form is

t_{vertex} = - \frac{b}{2a}

with a = - 16 and b = 88

t = - \frac{88}{-32} = 2.75 seconds ← time taken to reach max

to find the max height evaluate f(2.75 )

f(2.75 ) = - 16( 2.75)² + 88(2.75) + 12 = - 121 + 242 + 12 = 133 feet

Suppose a family has a gross annual income of ​$36,000, What is the maximum amount the family should spend each month on a mortg
Talja [164]

Answer:

Step-by-step explanation:

Ok, if they make $36,000 every year, that means the maximum they can spend is $36,000.

If the mortgage is a monthly payment, and there are 12 months in a year, that means we will split the $36,000 over 12 different payments. To do that we will divide the 36,000 by 12

36,000 / 12 = $3,000

That means the most they can spend on mortgage is $3,000 per month.
