Answer:

To round up 1.16 to the nearest term is 1.2.

You have to round up the 6 so has to be added to 1.

The answer is 1.2

You want to round to the tenths, and the tenths spot is taken by a 1.
So, you use the 6 (in the hundredths spot) and since it is over 5, you boost it up.
The 1 will now become a 2, so the answer is 1.2.
A helpful phrase I use is “five or above, give it a shove. Four or below, keep it low.”

Write each expression as an algebraic (nontrigonometric) expression in u, u > 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:

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

THESE ARE SEPARATE QUESTIONS THAT I DECIDED TO COMBINE:

saul85 [17]

1). Her walking pace is (1.75 miles) / (50 minutes).

If you want it in units of (miles per hour), do it like this:

   (1.75 miles / 50 minutes) x (60 minutes / 1 hour)

   = ( 1.75 x 60 / 50 ) miles per hour.

2). The average change was

   (30 - 45) degrees / (5 minutes) .

I'm sure you can do the division and make an integer out of that.

3). Each bracelet cost $3.10.
Caroline bought five of them, so she spent $3.10 five times.
Either do the multiplication, or else write down $3.10 five times
and do the addition.

4). In order to factor the expression, the two terms would need
to have some common factor ... both terms need either a power
of 'x', or they need two numbers that have a common factor.
They don't both have an 'x', and 13 and 10 have no common factor.

5). Todd earned 'T' dollars.
Twice what Todd earned is 2T .
$350 more than that is 2T+350 .
The question says that 2,500 is exactly that amount,
so you can write
      2T + 350 = 2,500

Subtract 350 from each side:    2T    = 2,150

Divide each side by 2: (you can finish it now)
