Our math team had m students last year, but this year it has already n students! By what percent did the number of students grow

AlekseyPX

For this case we are going to assume the following:
m: whole number greater than zero.
n: integer greater than zero.
Where,
n> m
According to these assumptions, the percentage of growth is given by the following formula:
$(n / m) * 100 - 100$
Answer:
the number of students did grow by:
$(n / m) * 100 - 100$

Cos²x + sin^2x/cscx-cot^2x

Anna [14]

Answer:

Step-by-step explanation:

I am assuming you want to simplify this.

cos^2 x + sin^2 x = 1 and

csc^2 x = 1 + cot^2 x so csc^2x - cot^2 x = 1

So the answer is 1/1 = 1.

Please help finding the remaining roots

shusha [124]

Answer:

x = 3, x = - $\frac{7}{2}$

Step-by-step explanation:

Since x = 2 is a root then (x - 2) is a factor

2x³ - 3x² - 23x + 42 ÷ (x - 2)

= (x - 2)(2x² + x - 21)

solve 2x² + x - 21 = 0 for remaining roots

(2x + 7)(x - 3) = 0

equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

2x + 7 = 0 ⇒ x = - $\frac{7}{2}$
