The temperature inside a certain industrial machine at time t seconds after startup, for 0 < t < 10, is given by h(t) = 42
frutty [35]

Answer:

t= \frac{125}{38} s

Step-by-step explanation:

We are given the temperature inside the machine from startup until 10 seconds later, the formula is:

h(t)= 42 \cdot t +1 - 4\cdot t +2  (degrees \, C)

We want to know at what time t the temperature inside the machine will be equal to 128 °C.

So we set:

h(t)=128

42\cdot t+1-4\cdot t+2=128

Now, we rearrange the equation to keep terms with t on the left hand side and terms without t on the right hand side

42\cdot t-4\cdot t=128-1-2

and we simplify:

(42-4)\cdot t= 128-2-1= 125

38 \cdot t = 125

now it's easy to solve for t:

t=\frac{125}{38}

And thus we arrive to the solution.

Phil bought 700 shares of a company's stock for $9.29/share. He pays a broker a commission of $18 to buy and sell stock. After o
Zina [86]
It seems that you are looking for the yield of the shares of stocks after they were sold.
To solve, 
yield =( current total amount- previous total amount) / previous amountwherecurrent amount = $9.9/share*700share+ $18previous=$9.29/share*700 share
yield=[ (9.9*700)+18] -(9.29*700)/(9.29*700) x 100
yield= 6.8%
Shares of stocks yield = 6.8%
