We assume you intend

D(h)=35e^{-0.15h}

You want to evaluate this function for h=0 and h=8.

D(0)=35e^{0}=35\\D(8)=35e^{-0.15\cdot 8}\approx 10.54

The amount injected was 35 milligrams; 8 hours later 10.54 milligrams remained.

HELP PLEASE If L is the line through the point (-3,5) having a slope of 2/3 . Complete the equation of L
nalin [4]

point slope form  (y-y1) = m(x-x1)

y-5=(2/3)(x-(-3))

y-5=(2/3)(x+3)                    add 5 to each side and distribute

y= 2/3x +2/3 *3 +5

y = (2/3)x +2 +5  

y = (2/3) + 7

Write the given rate as a fraction in simplest form. 12 cups for every 39 people O 39/12 cups per person O 13/4 cups per person
Nata [24]

Answer:

4/13 cups per person

Step - by - step explanation:

Write the given rate as a fraction in simplest form. 12 cups for every 39 people

O 39/12 cups per person

O 13/4 cups per person

0 4/13 cups per person

O 12/39 cups per person

There are 39 people

12 cups are available

Determine the number of cups per person

Cups per person = 12 cups / 39 people

= 12/39 cups per person

Divide both numerator and denominator by 3

= 4/13 cups per person

Cups per person as a fraction in simplest form = 4/13 cups per person

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by th
Blababa [14]

Answer:

Step-by-step explanation:

so when the height is zero, that's when the rocket hits the ground.  The equation will have two zeros,  but one would be for a negative time,  or before the rocket is launched.    so we only one the one after the rocket is launched.

use the quadratic formula to solve for  x  ( which is time)

-124 +- sqrt [ 124^{2} - 4*(-16)*(127) ] / 2 (-16)

-124 +- sqrt [15376 + 8128 ] / -32

-124 +- sqrt [23504 ] / -32

-124 +- 153.310 / -32

if we take the positive part it will become the negative time so skip that one try the negative part 1st

-124 - 153.310 / -32

-277.310 / -32

8.6659 seconds to hit the ground.    ( time of flight)  aka   TOF

8.67 seconds  ( rounded to nearest 100th)
