Where can you find the auto sum tool in excel

timofeeve [1]

Answer: How Autosum Excel works. Step 1: place the cursor below the column of numbers you want to sum (or to the left of the row of numbers you want to sum). Step 2: hold down the Alt key and then press the equals = sign while still holding Alt. Step 3: press Enter.

Explanation:To sum a column of numbers, select the cell immediately below the last number in the column. ...

AutoSum is in two locations: Home > AutoSum, and Formulas > AutoSum.

Once you create a formula, you can copy it to other cells instead of typing it over and over. ...

You can also use AutoSum on more than one cell at a time.

Hello, I need help with a calculus FRQ. My teacher has given a hint that this last part has to do with the intermediate value th

lesya [120]

Answer:

Yes, at a time t such that (√2)/2 ≤ t ≤ 2.

Explanation:

To answer the question

Therefore, where the domain of the function is the set of all real numbers x for which f(x) is a real number we have

For Chloe's velocity

$C(t) = t\times e^{4-t^2} \ for \ 0\leq t\leq 2$

Finding the boundaries of the function gives;

$0\times e^{4-0^2} = 0$ and $2\times e^{4-2^2} = 2$

At t = 1, we have $1\times e^{4-1^2} = e^{3} = 20.086$

We find the maximum point as follows;

$\frac{\mathrm{d} \left (t\times e^{4-t^2} \right )}{\mathrm{d} x}=0$

From which we have;

$\frac{\mathrm{} e^{4-t^2} - t\times e^{4-t^2} \times2\times t }{(e^{4-t^2} )^2}=0$

$e^{4-t^2} - t\times e^{4-t^2} \times2\times t }=0$

$e^{4-t^2}(1 - t\times2\times t })=0\\e^{4-t^2}(1 - 2\times t^2 })=0\\$

$e^{4-t^2}=0$ or $(1 - 2\times t^2 })=0$

∴ 1 = 2·t² and from which t = (√2)/2

Hence the function C(x) is decreasing from t = (√2)/2 to t = 2

For Brandon

For 0 ≤ t ≤ 1, 1 ≤ B(t) ≤8 and for 1 < t ≤ 2, 8 < B(t) ≤ 1.5

1 ≤ f(x) ≤ 1.5

Given that the function B(t) is differentiable, therefore, continuous, there exists a point at which the function C(t) and B(t) intersects given that;

For 0 ≤ t ≤ (√2)/2, 0 ≤ C(t) ≤ 23.416 for (√2)/2 < t ≤ 2, 23.416 > C(t) ≥ 2

and for 0 ≤ t ≤ 0 1 ≤ B(t) ≤ 8 and for 1 < t ≤ 2, 8 > B(t) ≥ 1.5

Therefore, the curves intersect at in between (√2)/2 ≤ t ≤ 2.

Ok so. What would you do if ur mom and dad said they ordered your x mas gifts online, buuuttt, that your gifts were not going to

vovangra [49]

Answer:

Well I wouldn’t worry about it. The item will come sooner or later and you probaly won’t use it as much, try to ignore the item and stop watching things and reviews of the item because being impatient for the item to come is just gonna make you think it’s coming slower. but late items are not as late as you think, even during this corona thing. Items that arriving from other countries should take about 1-2 weeks and if its in the same country, d_elivery should be 5-7 days Max. Even with corona, planes aren’t slowed down, they just cut the amount planes but not even by a quarter so plane‘s schedule should usually be on time and if delayed, it shouldn’t make you wait for another week, It should take about 2-3 days. So don’t trust the manufacturer if they
