Genrish500 [490]3 years ago
3 0


6:45a to 7:45  = 1 hour

7:45 to 8:45  = 2 hours

8:45 to 9:45  = 3 hours

9:45 to 10:45 =  4 hours

10:45 to 11:45  = 5 hours

11:45 to 12:45  = 6 hours

12:45 to 1:45  =  7 hours

1:45 to 2:45  = 8 hours

2:45 to 3:00  = 8 hours and 15 minutes

then just add the 28 minutes to the 15 minutes

28 + 15 = 43

6:45a to 3:28p = 8 hours and 43 minutes.

Hope this helps.

Which best describes the transformation that occurs from the graph of f(x)=x^2 to g(x)=(x-2)^2+3?? ​
Leokris [45]

answer right 2, up 3

any function with the following form is a transformation from f(x) = x²

g(x) = (x – a)² + b

were a moves the function to the right when a is a positive number and to the left when its a negative number, and b moves the function up when b is positive and down when its negative.

then for a=2 positive and b=3 positive, we have

right 2, up 3

"Trigonometric Models" (50 POINTS)<br> Is my graph right?
ch4aika [34]

Answer:

Yes, this graph is absolutely right for the function y = 2\sin(2x)-3.

Step-by-step explanation:

firstly we will calculate amplitude, period, phase shift, and vertical shift.

Use the standard form a\sin(bx-c)+d to calculate the values of amplitude, period, phase shift, vertical shift.

here a = 2

     b = 2

     c = 0

    d = -3

Amplitude = |a|  = 2

period = \frac{2\pi}{|b|}

           = \frac{2\pi}{2} = \pi

phase shift = \frac{c}{b} = 0

and vertical shift = d = -3

so, by using this information, if we plot the graph then the graph obtained will be same as the given graph.

A country's population in 1994 was 182 million. In 2002 it was 186 million. Estimate the population in 2004 using the exponentia
iogann1982 [59]
\bf =ae^{kt}\qquad &#10;\begin{cases}&#10;1994\impliedby \textit{year 0, starting point}\\&#10;t=0\qquad P=182&#10;\end{cases}\implies 182=ae^{k0}&#10;\\\\\\&#10;182=a\cdot e^0\implies 182=a\cdot 1\implies 182=a&#10;\\\\\\&#10;thus\qquad P=182e^{kt}\\\\&#10;-------------------------------\\\\

\bf P=182e^{kt}\qquad &#10;\begin{cases}&#10;2002\impliedby \textit{8 years later}\\&#10;t=8\qquad P=186&#10;\end{cases}\implies 186=182e^{k8}&#10;\\\\\\&#10;\cfrac{186}{182}=e^{8k}\implies ln\left( \frac{93}{91} \right)=ln(e^{8k})\implies ln\left( \frac{93}{91} \right)=8k&#10;\\\\\\&#10;\cfrac{ln\left( \frac{93}{91} \right)}{8}=k\implies 0.0027\approx k\implies \boxed{P=182e^{0.0027t}}

what's the population in 2004?  well,  from 1994 to 2004 is 10 years later, so t = 10

plug that in, to get P for 2004

Ann is going on vacation. Ann dog food for a pet sitter to feed her dog Maggie while she's away she leaves 24 cans of wet food a
docker41 [41]
1/4x = 24 for cans
Multiply both sides by 4 (the multiplicative inverse of 1/4)
x = 96 days

3/4x = 38 for dry food
Multiply both sides by 4
3x = 152
x = 50.666667

So I would say Ann can be gone 50 days before Maggie runs out of food. I don’t think they would count the 2/3 of a day. She will run out of dry food before canned food.
