Unit 0 algebra review functions graphing linear equations

1 answer:

AleksAgata [21]3 years ago

Linear Equations:

y = mx + b

The y will of course, be the y coordinate

The m, would be the slope

X, the x coordinate

B, the y intercept

I'm not really sure what your question is, but to graph these, first put a dot at the y intercept, or if there is none, just 0. Then, take the slope, and place a point accordingly, for example, if the slope was 1, then the line would move up one unit per every x coordinate, if that makes any sense. And then, connect the two, and draw the line.

Did that make any sense?

Answer:

A=152

K= -Ln(0.5)/14

Step-by-step explanation:

You can obtain two equations with the given information:

T(14 minutes) = 114◦C

T(28 minutes)=152◦C

Therefore, you have to replace t=14, T=114 and t=28, T=152 in the given equation:

$114=190-Ae^{-14k} (I) \\152=190-Ae^{-28k}(II)$

Applying the following property of exponentials numbers in (II):

$e^{a}.e^{b}=e^{a+b}$

Therefore $e^{-28k}$ can be written as $e^{-14k}.e^{-14k}$

$152=190-Ae^{-14k}.e^{14k}$

Replacing (I) in the previous equation:

$152=190-76e^{-14k}$

Solving for k:

Subtracting 190 both sides, dividing by -76:

$0.5=e^{-14k}$

Applying the base e logarithm both sides:

Ln(0.5)= -14k

Dividing by -14:

k= -Ln(0.5)/14

Replacing k in (I) and solving for A:

$Ae^{-14(-Ln(0.5)/14)}=76\\Ae^{Ln(0.5)} =76\\A(0.5)=76$

Dividing by 0.5

A=152
