Answer:
Step-by-step explanation:
With reference < H
perpendicular (p) = 12
base (b) = 5
so now
tangent of < H
= p / b
= 12 / 5
hope it helps :)
5 red, 3 blue, 7 white.....total of 15
probability of 1st drawn being red : 5/15 reduces to 1/3
without replacement
probability of 2nd being red : 4/14 reduces to 2/7
probability of both : 1/3 * 2/7 = 2/21 <==
Answer:
The graph in the attached figure
see the explanation
Step-by-step explanation:
we have
![y=\sqrt{-x-3}](https://tex.z-dn.net/?f=y%3D%5Csqrt%7B-x-3%7D)
we know that
The radicand must be greater than or equal to zero
so
![(-x-3)\geq 0](https://tex.z-dn.net/?f=%28-x-3%29%5Cgeq%200)
solve for x
Adds 3 both sides
![-x\geq 0+3](https://tex.z-dn.net/?f=-x%5Cgeq%200%2B3)
![-x\geq 3](https://tex.z-dn.net/?f=-x%5Cgeq%203)
Multiply by -1 both sides
Remember that, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
![x\leq -3](https://tex.z-dn.net/?f=x%5Cleq%20-3)
so
The domain of the function is the interval (-∞,-3]
For x=-3 ---> the value of y=0
The range is the interval {0,∞)
therefore
The graph in the attached figure
Answer:
1.
A slope is a surface of which one end or side is at a higher level than another; a rising or falling surface.
"he slithered helplessly down the slope"
Some real life examples of slope include: in building roads one must figure out how steep the road will be. skiers/snowboarders need to consider the slopes of hills in order to judge the dangers, speeds, etc. when constructing wheelchair ramps, slope is a major consideration.
20 raise the power 7
Step-by-step explanation:
Which clearly means 20 × itself 7 times
