sinx-1 evaluates to s-1

<span>tanx+secx evaluates to t+sHere, you are trying to multiply two binomials together. To work this problem, we'll use the "F.O.I.L." method. First, we'll multiply the two First terms, the s and t together. Second, we'll multiply the two Outer terms, the s and s together. Third, we'll multiply the two Inner terms, the -1 and t together. Lastly, we'll multiply the two Last terms, the -1 and s together. The correct answer is st + s^2 - t - sThank you for posting your question. I hope that this answer helped you.

Course Grade You were 6 points shy of a B in yo

Oksanka [162]

The point total possible for the given course is equal to 500.

What is a Percent?

A ratio whose second term is 100 is known as a percent.
Parts per hundred are used in percentages.
The mathematical representation of percent is %.
The percent formula is given as, $x=p \times b$ , where b is the base number, x is the number being compared to b, and p is the percent in decimal form.

In the question, it is given that you were 6 points shy of a B and the current total points you have is 394.

So, the total number of points you require for a B is calculated as,

$394+6=400$

So, the value of x is 400.

It is given that you need 80% of the course total for a B.

$\implies p=\frac{80}{100}\\ \implies p=0.8$

Here, we have to find the base number (b).

We have, x = 80% of b

$\implies x=0.8 \times b\\\implies 400= 0.8 \times b\\\implies x=\frac{400}{0.8}$

Simplifying, we get

$x=500$

Therefore, 500 points were possible in the course.

What will an investment of 6000 Euro at 7% p.a compound interest amount to after 5 years if the interest is compounded:

Over [174]

S = P[1 + (r / m)]^(m * t)

S = ?

P = 6000 euro

r = 0.07

m = 12

t = 5

S = 6000[1 + (0.07 / 12)]^(12 * 5)

S = 6000(1.00583)^(60)

S = 6000(1.4176...)

<span>S = 8505.75 euro
