Answer:

-(-x² + 50x - 9); x² -50x + 9

Step-by-step explanation:

You find the opposite of a polynomial P by changing the sign of every term in P.

P = -x² + 50x - 9

One way to get -P is to put a negative sign in front of the whole expression.

-P = -(-x² + 50x - 9)

Another way is to distribute the -1 inside the parentheses.

-P = x² -50x + 9

40% of the groups budget was spent on activities. If $64,000 was spent on the activities, what was the full budget? solve with t

Andre45 [30]

Answer:

The full budget has a total value of $160,000

Step-by-step explanation:

This is a simple ratio problem and can be solved using the Rule of Three property. The Rule of Three is used to compare two ratios and find the missing part. In this case the ratios would be the following.

$\frac{64,000}{40 percent} = \frac{x}{100 percent}$

$\frac{64,000 * 100 percent}{40 percent} = \frac{x}$

$\frac{6,400,000}{40 percent} = \frac{x}$

$160,000= \frac{x}$

So now we know that 100% (The full budget) has a total value of $160,000.

Integral Calculation

Tatiana [17]

Answer:

$\frac{4}{3(e^2+1)}$

Step-by-step explanation:

We want to evaluate:

$\int\limits^1_{-1} {\frac{x^2+1}{e^2+1} } \, dx$

This is the same as:

$\frac{2}{e^2+1} \int\limits^1_{0} {x^2+1} \, dx$

We integrate to obtain:

$\frac{2}{e^2+1} (\frac{x^3}{3}+x)|_0^1$

We evaluate to obtain:

$\frac{2}{e^2+1} (\frac{1^3}{3}+1)=\frac{4}{3(e^2+1)}$
