Try using Symbolab, I use it all the time it gives the correct answer and it gives good explanations.
Answer <u>(assuming it can be in slope-intercept form): </u>
y = x - 5
Step-by-step explanation:
1) First, find the slope of the equation. Use the slope formula,
, and substitute the x and y values of the given points into it. Then, solve:
2) Now that we know the slope and at least one point the line crosses through, we can write an equation of the line in point-slope form, or
. Substitute
,
, and
for real values.
Since
represents the slope, substitute 1 for it. Since
and
represent the x and y values of a point the line intersects, use any one of the given points (either one is fine, either way the equation will represent the same line) and substitute its x and y values into the equation. (I chose the point (6, 1), as seen below.) Finally, isolate y to put the equation in slope-intercept form.

Answer:
r = 3.5 * .5^(t/65); around 117.5 days
Step-by-step explanation:
r = remaining substance
t = time in days
The half life is 65 day, meaning the .5 must be put to a power of t/65.
The initial substance was 3.5, which we must substitute in.
After using logarithms to solve our new equation, we are left with t=(about)117.5 days for there to be less than 1 gram of substance remaining.
Answer:

Step-by-step explanation:
Given

Calculate the diameter
The area of a sector is:

Substitute values for Area and 

Divide both sides by 

Make
the subject



Take positive square roots of both sides



The diameter is then calculated as:
