What is the initial value of the exponential function shown on the graph? a. 0, b. 1, c. 2, d. 4

Answer:

x =2968

Step-by-step explanation:

7277+x=10245

Subtract 7277 from each side

7277-7277+x=10245-7277

x =2968

Answer:

x = 2968

Step-by-step explanation:

7277 + x = 10245

-7277         -7277 (Subtract 7277 from both sides to leave x by itself)

_____________

           x  = 2968

Answer:

-294

Step-by-step explanation:

Answer:

An interesting experiment is given. We need to address various questions based on our knowledge of calculus.

Step 2

Part (a)

Time taken for the radius to grow to 2 cm = t1 = r/0.5 = 2/0.5 = 4 hours

Time taken for the radius to become 0 = t2 and the same can be obtained by solving:

r = 2 - √t2 = 0

Hence, t2 = 22 = 4 hours

Hence, the time duration of the entire experiment (from the introduction of the bacteria until its disappearance) = t1 + t2 = 4 + 4 = 8 hours

Step 3

Part (b)

r(t) = 0.5t for 0 ≤ t ≤ 4

and

r(t) = 2 - √(t - 4) for t > 2

Step-by-step explanation:

Answer:

A. y=-1/4x

Step-by-step explanation:

We have the information 3y=12x-9, the lines are perpendicular, and the new line passes through (-4,1). First, you want to put the original equation into slope intercept form by isolating the y, to do this we need to divide everything by 3 to get y=4x-3. The slopes of perpendicular lines are negative reciprocals so you need to find the negative reciprocal of 4, so flip it to 1/4 and multiply by -1, we get the slope of the new line as -1/4. So far we have the equation y=-1/4x+b. We are given a point on the line, (-4,1), we can plug these into the equation as x and y to solve for the y-intercept, b. You set it up as 1=-1/4(-4)+b. First you multiply to get 1=1+b, then you subtract 1 from both sides to isolate the variable and you get b=0. Then you can use b to complete your equation with y=-1/4x, or letter A.

Answer:

Letter E represents the maximum of the data set on the box-plot.

Step-by-step explanation:

We now that in the given box-plot we have:

Letter A represents the minimum value of the data set.

Also in the given box of the whisker-box plot the lower value in the box represents the lower quartile or first quartile i.e. i.e. letter B.

Also, the middle value in the box-plot represents the middle quartile or median of the data i.e. i.e. letter C.

And the maximum value on the box represents the upper quartile i.e. i.e. letter D.

The maximum value of the data set is represented by letter E.

E is your correct answer cause that's the maximum range in that data there is no other range going past it.
