Eva8 [605]3 years ago
6 0
The answer is: 1 + 5a ; or, 5a + 1 .
______________________________
Given the expression:
______________________________
<span>1 + 10a − 5a ; 
________________
→ We identify the "like terms" ; 
___________________________
→ which are "10a" and ( "-5a") ;
____________________________
→ 10a </span>− 5a = 5a ; 
_________________________________
→ 1 + 5a ; is the most simplified; or write the expression as: 5a +1 .

A contract between a manufacturer and a consumer of light bulbs specifies that the mean lifetime of the bulbs must be at least 1
Alex17521 [72]

Answer:

Follows are the solution to the given points:

Step-by-step explanation:

In point a:

In this sense, describe what type of error I will be.

Type I error: to conclude that perhaps the mean bulb life would be less than three hours when it becomes (at least) 3 hours.

In point b:

Describe throughout this context what the Type II error becomes.

An error of type II: never assuming that its bulbs' mean lifetime is much less than 3 hours. three hours at least

In point c:

What error — type I and type II — would further impact the interaction between the manufacturer and the customer?

A Type II error is probably further problematic because it means that even the buyer will buy bulbs that do not last long.

Let x represent the regular price of any book in the store. Write an expression that can be used to find the sale price of any b
arsen [322]

Answer:

(a) The sale price of any book in the store is 0.70 <em>x</em>.

(b) The regular price of the book bought by Jerome was $12.80.

Step-by-step explanation:

The complete question is:

All books in a store are being discounted by 30%.  Let x represent the regular price of any book in the store. (a) Write an expression that can be used to find the sale price of any book in the store. (b) Jerome bought a book on sale at the store. The sale price of the book was $8.96. Write an equation to determine the regular price of the book Solve your equation to find the regular price of Jerome's book to the nearest cent.

Solution:

The regular price of any book in the store is denoted by, <em>x</em>.

(a)

The discount percentage is: <em>d</em>% = 30%.

The sales price of the book is:

Sales Price = Regular Price - Discount

            SP =x-(x\times 30\%)

                  =x-0.30x\\=0.70x

Thus, the sale price of any book in the store is 0.70 <em>x</em>.

(b)

The sales price f book bought by Jerome is, SP = $8.96.

Jerome bought the book at the same discount, i.e. 30%.

Compute the regular price of the book bought by Jerome as follows:

SP =x-(x\times 30\%)

8.96=0.70x

   x=\frac{8.96}{0.70}

      =12.80

Thus, the regular price of the book bought by Jerome was $12.80.

Write each expression as an algebraic​ (nontrigonometric) expression in​ u, u &gt; 0.
max2010maxim [7]

Answer:

\displaystyle \sin\left(2\sec^{-1}\left(\frac{u}{10}\right)\right)=\frac{20\sqrt{u^2-100}}{u^2}\text{ where } u>0

Step-by-step explanation:

We want to write the trignometric expression:

\displaystyle \sin\left(2\sec^{-1}\left(\frac{u}{10}\right)\right)\text{ where } u>0

As an algebraic equation.

First, we can focus on the inner expression. Let θ equal the expression:

\displaystyle \theta=\sec^{-1}\left(\frac{u}{10}\right)

Take the secant of both sides:

\displaystyle \sec(\theta)=\frac{u}{10}

Since secant is the ratio of the hypotenuse side to the adjacent side, this means that the opposite side is:

\displaystyle o=\sqrt{u^2-10^2}=\sqrt{u^2-100}

By substitutition:

\displaystyle= \sin(2\theta)

Using an double-angle identity:

=2\sin(\theta)\cos(\theta)

We know that the opposite side is √(u² -100), the adjacent side is 10, and the hypotenuse is u. Therefore:

\displaystyle =2\left(\frac{\sqrt{u^2-100}}{u}\right)\left(\frac{10}{u}\right)

Simplify. Therefore:

\displaystyle \sin\left(2\sec^{-1}\left(\frac{u}{10}\right)\right)=\frac{20\sqrt{u^2-100}}{u^2}\text{ where } u>0
