Answer:

h'(x) = -10x + 20

Step-by-step explanation:

To get the derivative of $ax^{n}$ , simply use the following formula:

$a(n)x^{n-1}$

We have the function, h(x) = -5x^2 + 20x

Using the formula, we get the derivative to be:

-10x + 20

so h'(x) = -10x + 20

Explain why you might want to write very large and very small numbers like the ones in the example problem in scientific notatio

slava [35]

Answer:

Extremely large and small numbers that have many zeros are long to write and take up a lot of room. So, by using scientific notation a number can be written shorter. For example, numbers such as 295,000,000,000 can be shortened to 2.95x $10^{11}$ . This is easier to write and understand. This is why the scientific notation is used over standard.

Find the value of c that makes each trinomial a perfect square<br> x^2-19x+c<br> Please Help! :)

tensa zangetsu [6.8K]

The value of c is $\frac{361}{4}$

Explanation:

Given that the trinomial is $x^2-19x+c$

We need to determine the value of c such that the trinomial is a perfect square.

The value of c can be determined using the formula,

$c=(\frac{b}{2})^2$

From the trinomial, the value of b is given by

$b=-19$

Substituting the value of b in the above formula, we have,

$c=(\frac{-19}{2} )^2$

Squaring both the numerator and denominator, we have,

$c=\frac{361}{4}$

Thus, the value of c is $\frac{361}{4}$ which makes the trinomial a perfect square.

14. A recipe calls for % cup brown sugar for

12345 [234]

Answer:

1 1/8 cup of brown sugar.

Step-by-step explanation:

Here is the correct question: A recipe calls for 3/4 cup brown sugar for each 2/3 cup white sugar. How many cups of brown sugar per cup of white sugar is this?

Given: 3/4 cup of brown sugar for each 2/3 cup of white sugar.

Finding requirement of brown sugar for 1 cup of white sugar.

∴ Each 2/3 cup of white sugar require 3/4 cup of brown sugar.

Now, 1 cup of white sugar require brown sugar = $\frac{\frac{3}{4} }{\frac{2}{3} } cups$

= $\frac{3}{4} \times \frac{3}{2} = \frac{9}{8} \ cup$

Thus, we can say $\frac{9}{8}$ = 1 1/8 cup of brown sugar is required per cup of white sugar.
