Answer:2

Step-by-step explanation: cot2θ+cosec2θ

= $\frac{cot^{2}\theta }{2cot\theta} +\frac{1}{sin^{2}\theta }$

= $\frac{2^{2}-1 }{2*2} \\$ $\frac{1}{2cot\theta}$ /1+cot²θ

= $\frac{4-1}{4} +\frac{1+2^{2} }{2*2}$

= $\frac{3}{4} +\frac{5}{4}$

= $\frac{8}{4}$

= $2$

Write an equation in standard form for a line that passes through (2,2) and (0,-3).

asambeis [7]

So,

The standard form is:
y = mx + b

First, we find "m," the slope. Subtract the y-coordinates from each other. Do likewise with the x-coordinates.

2 - -3 = 5
2 - 0 = 2

Slope = 5/2

$y= \frac{5}{2} x+b$

Now, we can substitute the second solution into this equation for x and y and solve for "b."

$-3= \frac{5}{2} *0+b$

$-3= b$

Now we have our complete equation.

$y= \frac{5}{2} x-3$

Determine the equation from the table listed below Will give Brainly

yanalaym [24]

Answer:

It's c) y = 15x +200

Step-by-step explanation:

First divide the total cost by the number of students using two values of the table:

1500/100 = 15

This is the number that multiply x in the equation.

In the options given, there is just one equation that have 15 multipling x, so that must be the answer

Twenty-seven minus of a number (x) is not more than 36. What is the number? A. x > 42 B. x ≥ -6 C. x < 3 D. x ≤ -6

natali 33 [55]

Answer:

Step-by-step explanation:

since it hints that it is less than we can see that B gives it to us also it can't be A cuz 42 is greater than 36

so it is B

Use the formula v = u + at to find the velocity when the initial velocity is 3 m/s the acceleration is 1.5 m/s the time is 7 s

vichka [17]

$answer \\ 13.5 \: m/s \\ given \\ initial \: velocity(u) = \: 3 \: m/s \\ acceleration(a) = 1.5 \: m/s ^2\\ time(t) = 7 \: second \\ now \\ v = u + at \\ or \: v = 3 + 1.5 \times 7 \\ \: or \: v = 3 + 10.5 \\ v = 13.5 \: m/s \\ hope \: it \: helps$
