Mathematics
1 answer:
Marianna [84]3 years ago
8 0

Answer: The required derivative would be \dfrac{dy}{dx}=e^x

Step-by-step explanation:

Since we have given that

y=e^x-4

We need to find the derivative of the above function:

As we know that

\dfrac{d}{dx}e^x=e^x

and

derivative of constant term = 0

So, the derivative  w.r.t. x would be

\dfrac{dy}{dx}=e^x-0=e^x

Hence, the required derivative would be \dfrac{dy}{dx}=e^x

The formula for the circumference, C, of a circle with given radius, r, is C = 2nr.
LekaFEV [45]

Answer:

C. 22

Step-by-step explanation:

C = circumference

n (pi) = 22/7

r = 3 1 /2

Plug in the numbers for each variable.

C = 2x (22/7) x (3 1/2)

Change the mixed number inIto an improper fraction by multiplying 3 x 2 and adding the 1 which gives us 7 over 2 because 2 is our denominator  so, 3 1/2 = 7/2. It also helps to have 1 as the denominator for 2.

C = (2/1) x (22/7) x (7/2)

Lastly, just multiply the numerators across which give us 308 then multiply the denominators across which gives us 14, so then we divide 308 by 14 and get 22.

At the grocery store you choose to buy 4 items that cost: $2.69, $14.45, $8.05, and $13.95. Estimate the total cost of your groc
Travka [436]

Answer:

$39

Step-by-step explanation:

First, let's get the values of each number by <u>rounding them off to the nearest dollar before adding them</u>.

  • Remember that you have to <em>round off the number up</em> if it is being followed by a number<em> </em><u><em>equivalent to 5 and above.</em></u><em> </em>You have to <em>retain the number</em> if it is followed by a<u><em> number less than 5</em></u>.

1. $2.69 = $3

2. $14.45 = $14

3. $8.05 = $8

4. $13.95 = $14

Now that you have the rounded off numbers, you may add them.

Let's solve.

  • $3 + $14 + $8 + $14 = $39

The estimated total is $39.
