Sin =9/15 . Find tan 0

Mathematics
1 answer:
ELEN [110]3 years ago
3 0

Answer:

c. 9/12

Step by step explanation.

Given: sin = 9/15

and,

sin =  \frac{opp.}{hyp.}

tan =  \frac{opp.}{adj.}

thus, find adj. side

by using Pythagoras theorem

{c }^{2} =   {a}^{2}  +  {b}^{2}

then,

let adj. side be a^

{a}^{2}  =  {c}^{2}  -  {b }^{2} \\  {a}^{2}   =  {15 }^{2}  -  {9}^{2}  \\  {a}^{2}  = 144 \\ a = 12

thus,

adj. side is 12

then,

tan of the angle = 9/12

What is the domain and range of g(x)= -|x+2| -1
solmaris [256]

g(x)= -|x+2| -1


The domain is the input values, or x values

it is all real number


The range is the output values, or g(x)

the absolute value at is smallest is 0

0-1 is -1  this is the max since the absolute value is multiplied by -1

g(x) <=-1

the output is less than or equal to -1

A child’s wading pool has a diameter of 5 feet and a height of 2 feet. How much water would it take to fill the pool?
Svetradugi [14.3K]

Answer:

12.5π or ≈39.27

Step-by-step explanation:

The formula for finding the volume is V=πr^2*d (where h is the height and r is  the radius).

Plug in the values: V=π(2.5)^2*2 (Diameter=2*Radius)

Solve: V=6.25π*2

V=12.5π

V≈39.27

John made a rectangle pen for his dog using 28 feet of fencing. If the width of the pen is 2 feet more than one-half the length,
kati45 [8]
Okay, so you know that the perimeter of the pen is 28 feet. Now we need the separate side lengths.

P = 28 ft.
Length = x
Width = (1/2)x + 2

So now we can plug in the little equations of length and width into a perimeter formula:
 2(x) + 2((1/2)x + 2) = 28
Distribute the 2's and solve as needed.
2x + x + 4 = 28
3x + 4 = 28
3x = 24
x = 8

To find the width, just plug in 8 for x in our little equation:
(1/2)(8) + 2
= 6

So, the length is 8 feet and the width is 6 feet.
