Answer:

B is correct graph.

Step-by-step explanation:

Given: A pizza is taken out of an oven and placed on a counter. The temperature, T, in degrees Fahrenheit, of the pizza after t minutes is modeled by the function, T=72+200e^{-0.045t}

We need to choose the correct graph.

First we make table of given model for different value of t. We will take some random value of t and solve for T

t should be greater than 0 because time is positive.

      t          T=72+200e^{-0.045t}

     0           T=72+200e^{-0.045\cdot 0}=272

     10          T=72+200e^{-0.045\cdot 10}=199.53

     20         T=72+200e^{-0.045\cdot 20}=153.32

     30         T=72+200e^{-0.045\cdot 30}=123.85

Plot the points on graph and match with correct option.

Please see the attachment for graph.

Hence, B is correct graph.

The lines graphed below are parallel.the slope of the slope of red line is 2/5 .what is the slope of the green line
Yuliya22 [10]

Answer:

\large\boxed{\text{the sloe}\ m=\dfrac{2}{3}}

Step-by-step explanation:

\text{Let}\\\\k:y=m_1x+b_1\\\\l:y=m_2x+b_2\\\\l\ \parallel\ k\iff m_1=m_2\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}

\text{We have the slope}\ m_1=\dfrac{2}{5}.\\\\\text{The slope of parallel line is the same:}\ m_2=\dfrac{2}{5}

Solve the following equation for a. Be sure to take into account whether a letter is
Zina [86]

Answer:

a = \frac{r-q}{g}

Step-by-step explanation:

Given

ga + q = r ( subtract q from both sides )

ga = r - q ( isolate a by dividing both sides by g )

a = \frac{r-q}{g}
