Solve each equation for x.a)x-1=0b)x+1=0 c)x²-1=0 d)x²+1=0

lesya692 [45]

Answer

given,

a) x-1=0

adding both side with 1

x = 1

b) x + 1 =0

subtracting both side by 1

x = -1

c) x²- 1 =0

x² = 1

taking square root

x = √1

x = 1

d) x²+ 1 =0

x² = -1

taking square root

x = √-1

x = i (iota)

Find csc0<br><br> Please Help!!!!!

<h3>Answer: -5/4</h3>

=======================================================

Explanation:

The terminal point is at (x,y) = (3,-4)

Apply the pythagorean theorem to find that x^2+y^2 = r^2 solves to r = 5. This is the length of the hypotenuse.

Then we can determine the cosecant of the angle theta using the formula below

csc(theta) = hypotenuse/opposite

csc(theta) = r/y

csc(theta) = 5/(-4)

csc(theta) = -5/4

Side note: csc = 1/sin

There are 10 students in a class. The teacher chooses 2 students to go to the

CaHeK987 [17]

Answer:

The number of ways in which students were chosen is 45 ways .

Step-by-step explanation:

Given as :

The number of students in a class = x = 10

The number of students chosen by teacher to go to library = y = 2

Let The number of ways in which students were chosen = n ways

<u>Now, According to question</u>

So, number of ways in which students were chosen = $_{y}^{x}\textrm{C}$

Or, n ways = $_{2}^{10}\textrm{C}$

Or, n = $\frac{\L 10}{\L( 10-2)\times \L 2}$

Or, n = $\frac{\L 10}{\L8\times \L 2}$

Or, n = $\frac{10\times 9\times \L 8}{\L 8\times \L 2}$

Or, n = $\frac{10\times 9}{2\times 1}$

Or, n = 5 × 9

i.e n = 45

So, The number of ways in which students were chosen = n = 45 ways

Hence,The number of ways in which students were chosen is 45 ways . Answer
