Natalka [10]4 years ago
3 0

Step-by-step explanation:

the mistake was made when the value of cos 3 pi over 2 was calculated.

tan(A-B)= ?since tan=sin/cos

<u>sin</u><u>(</u><u>A-B</u><u>)</u> = <u>sinAcosB-cosAsinB</u>

cos(A-B) cosAcosB+sinAsinB

divide by cos on the RHS

tan(A-B)= <u>tanA-tanB</u>

1+tanAtanB

I put a picture
Ksivusya [100]

Answer:

Yes, an arrow can be drawn from 10.3 so the relation is a function.

Step-by-step explanation:

Assuming the diagram on the left is the domain(the inputs) and the diagram on the right is the range(the outputs), yes, an arrow can be drawn from 10.3 and the relation will be a function.

The only time something isn't a function is if two different outputs had the same input. However, it's okay for two different inputs to have the same output.

In this problem, 10.3 is an input. If you drew an arrow from 10.3 to one of the values on the right, 10.3 would end up sharing an output with another input. This is allowed, and the relation would be classified as a function.

However, if you drew multiple arrows from 10.3 to different values on the right, then the relation would no longer be a function because 10.3, a single input, would have multiple outputs.

What is the slope and the y-intercept of f(x)= -2x+6
murzikaleks [220]

Answer:

slope = - 2 and y- intercept = 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 6 ← is in slope- intercept form

with slope m = - 2 and y- intercept c = 6

Step-by-step explanation:

as we know that

The number of ways to pick 5 numbers from 45  are

45C_5

\frac{45\times44\times43\times42\times41}{5\times4\times3\times2\times1}|

= 1,221,759.

There are 32 ways to pick a gold ball so total number of ways to get  6 matching numbers is

1221759×32

= 39,096,288
