Answer 2

Answer:

Answer:

Basic Formulas

sin θ = Opposite Side/Hypotenuse.

cos θ = Adjacent Side/Hypotenuse.

tan θ = Opposite Side/Adjacent Side.

sec θ = Hypotenuse/Adjacent Side.

cosec θ = Hypotenuse/Opposite Side.

cot θ = Adjacent Side/Opposite side.

Hope this helps :)

Find the domain of the following function:

\[ y=\sqrt{x} \]
\[y= \sqrt{x+3} \]

Answers

Firstly we have to determine the domain of the function $y=√(x)$

The domain of the function is the set of values for which the function is real and defined.

In the function $y=√(x)$ we can clearly observe that for the negative values of x , the value of y will not be real.

So, the domain for this function is $[0,\infty )$ or $x\geq 0$ .

The second function is $y=√((x+3))$

In this function we can clearly observe that for the values of x less than -3, the function is not real.

So, the domain for this function is $[-3,\infty )$ or $x\geq -3$

$y=√(x)$

As we know, the square root of negative numbers.

Hence, the x must be a positive value and greater than 0.

So, x:x∈[0,∞)

$y=√(x+3)$

$x+3\geq 0$

subtracting 3 from both sides

$x\geq -3$

x:x∈[-3,∞)

For the data in the table does y vary directly with x? If it does write an equation for the direct variation X Y
16 4
32 16
48 36

A)yes; y=2x
B)yes; y=1/4x
C)yes; y=1/8x
D) No; y does not vary directly with x

Answers

Answer:

D) No; y does not vary directly with x.

Step-by-step explanation:

We can affirm that y varies directly with x, that is, that y is directly proportional to x if they fulfill the following condition.

y/x = k

where,

k is a constant number

We have 3 ordered pairs:

a) (16, 4)

b) (32, 16)

c) (48, 36)

If we perform y/x for each ordered pair,

a) 4/16 = 0.25

b) 16/32 = 0.50

c) 36/48 = 0.75

Since y/x is not constant, y does not vary directly with x.

I think the answer is D because when I try to solve them they don't equal each other

The speed of a space shuttle orbiting the earth is 28,325mph.How many miles does the space shuttle travel in 5 days?

Answers

In one day, there is 24 hours, so in 5 days, there is 120 hours.
As you've got this information, you've then got to multiply the two numbers together.
28,325*120= 3399000
Therefore, the space shutt;e travels 3,399,000 miles in 5 days
Hope this helps :)

First to find out the hours times 24 (as there are 24 hours in a day) by the number of days
24x5=120
Then times the hours by the speed
28,325*120=3399000
that will be the amount of miles it will have travelled in the time
