Answer : domain: {x | x is a real number}; range: {y | y >- 8}
the domain and range of
For exponential function , there is no restriction for x
So domain is all real numbers
For exponential function ,
The range is y > b
The range of is y> -8
domain: {x | x is a real number}; range: {y | y > –8}
Answer/Step-by-step explanation:
The ratio of the enlargement to the original = A'E' to AE = A'E':AE = A'E'/AE
AE = 2.5
A'E' = 4
Ratio of the enlargement to the original = 4:2.5 = 1.6:1
To convert to percentage, divide 4 by 2.5 and multiply by 100.
Answer:
Jude is not correct
Step-by-step explanation:
The volume of a square pyramid is given as:
where a = base edge and h = height
Hence, the volume of the square pyramid with base edge of 7 in and height of 7 in is:
V = ≅
The volume of a cylinder is given as:
where r = radius and h = height
Hence, the volume of a cylinder with radius of 7 in and height of 7 in is:
V = ≅
Since their volumes are not equal, Jude is not correct.
Answer:
Height of the kite from the ground is 29.2 feet.
Step-by-step explanation:
For better explanation of the solution, see the figure attached :
The angle formed by the height of kite to that of the surface of the ground is right angle.
⇒ m∠ABC = 90°
Let angle of elevation be θ
Now, to find height of the kite : find length of AB
In right angled triangle ABC , using tan rule, we have
Hence, Height of the kite from the ground is 29.2 feet.
