Fundamental theorem of calculus<br> <img src="https://tex.z-dn.net/?f=g%28s%29%3D%5Cint%5Climits%5Es_6%20%7B%28t-t%5E4%29%5E6%7D

Answer:

$\displaystyle g'(s) = (s-s^4)^6$

Step-by-step explanation:

The Fundamental Theorem of Calculus states that:
$\displaystyle \frac{d}{dx}\left[ \int_a^x f(t)\, dt \right] = f(x)$

Where <em>a</em> is some constant.

We can let:
$\displaystyle g(t) = (t-t^4)^6$

By substitution:

$\displaystyle g(s) = \int_6^s g(t)\, dt$

Taking the derivative of both sides results in:
$\displaystyle g'(s) = \frac{d}{ds}\left[ \int_6^s g(t)\, dt\right]$

Hence, by the Fundamental Theorem:

$\displaystyle \begin{aligned} g'(s) & = g(s) \\ \\ & = (s-s^4)^6\end{aligned}$

Deborah bought a computer for 25% off the list price. If the list price is $2,428, how much did Deborah spend? A. $607 B. $1,821

Softa [21]

Answer:

Option A, $\$607$

Step-by-step explanation:

Given: Deborah bought a computer for $25\%$ off the list price.

The list price is $\$2,428$ .

To find: The amount Deborah spent on the computer.

Solution: We have,

List price of the computer $=\$2,428$ .

Deborah bought the computer for $25\%$ off the list price.

The amount Deborah spent on the computer $=25\% \times 2,428$

$=\frac{25}{100}\times2428=\frac{2428}{4} =\$ 607$ .

So, Deborah spent $\$607$ on the computer.

Hence, option A is correct.

Will give brainliest-H(t)=-16t^2+28t

____ [38]

For this case we have the following equation:
H (t) = - 16t ^ 2 + 28t
When the dolphin finishes a jump, then the height is equal to zero.
We have then:
-16t ^ 2 + 28t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 1.75 s
Therefore, the dolphin takes 1.75 seconds to make a jump.
Answer:
it will take for the dolphin to make one jump about:
t = 1.75 s

explain how you could use the greatest common factor of 8 and 20 in the distributive property to write 8 + 20 as a product

GenaCL600 [577]

Answer: 4(5+2) or 4(2+5)

Step-by-step explanation:

8 = 2*2*2

20 = 2*2*5

4(5+2) = 20+8
