Answer:
the first answer is correct answer
Hi there!

v = √2gh
Plug in the given velocity and acceleration due to gravity:
48 = √2(32)h
Square both sides:
2304 = 2(32)h
Simplify:
2304 = 64h
Divide both sides by 64:
h = 36 feet.
Answer:
option-A
option-D
Step-by-step explanation:
We are given a complex number as

we know that whenever we have

where
a is the real number
b is imaginary number
now, we can verify each statement
option-A:
we can see that
a=7
and
a is the real number
so, 7 will be real number
so, this is TRUE
option-B:
we know that

so, imaginary number is 
while it is mentioned square root 3 is the imaginary part of the number
so, this is FALSE
option-C:
We can see that coefficient of i is b
and

so, this is FALSE
option-D:
we know that
'a' and 'b' are sum of real and imaginary number
so, this is TRUE
Answer:
Step-by-step explanation:
The width = x
The length of the garden is three times the width => the length = 3x
The diagonal distance is five yards longer than the width=> the width=x+5
