Answer:
t = 9.08 sec
Explanation :
This requires the use of the kinematic equations.
u = initial velocity = 21.8 m/s
v = final velocity = 0
t = time = what we're trying to find.
So we use the equation that relates d, u, v and t. This is
d = distance = 99m
d = 
and since v = 0 this reduces to d = 
which rearranges to t = 
t = 
=9.08 seconds
t = 9.08 sec
Answer:
No, diagonal of square C is 70.71ft
Step-by-step explanation:
Given in the question that length of one square = 5 ft
Length of Square C = 10 small squares
1 square = 5 ft
10 square = 5ft * 10
= 50 ft
As we know that in a square all side are of equal length and make an angle of 90° at each corner.
So, by using pythagorus theorem
Diagonal of square² = side² + side²
Diagonal of square² = 2side²
Diagonal of square = √(2side²)
Diagonal of square = √2 (side)
where side = 50 ft
Diagonal of square = √2 (50)
Diagonal of square = 70.71 ft
14 red flowers so d because it says 4:7 so there is 8 yellow and 14 red so so fine the lowest common multiple thin divide both by same LCM and git your answer <span />
Answer:
x = 18 and y = 6√10
Step-by-step explanation:
First using pythagoras theorem on the small triangle
h² = 6² + 2²
h² = 36 + 4
h² = 40
h= √40
h = √4 * 10
h = 2√10
Using the similarity theorem;
y/2√10 = 6/2
y/√10 = 6
y = 6√10
To get x we will use the pythagoras theorem
y² = x²+6²
(6√10)² = x² + 36
360 = x² + 36
x² = 360 - 36
x² = 324
x = 18
Hence x = 18 and y = 6√10
This is the best i could find
