672 cm³
Step-by-step explanation:
10x7x9=630
2x3x7=42
630+42=672
Answer:
Step-by-step explanation:
cot(x)=cos(x)/sin(x)
sin(x) + cos(x) * cos(x)/sin(x) = 1/f(x)
(sin^2 + cos^(x))/sin(x) = 1 / f(x)
1 / sin(x) = 1 / f(x)
Taking the reciprocal of both sides, we get
sin(x) = f(x)
Answer:
0.375 second and 3.5 second
Step-by-step explanation:
The position can be modeled by a quadratic function
. We are tasked to find the time when a ball reaches a height of 27 feet. Therefore, let h = 27:

Solve for t:

Since the equation is quite complicated and more time-consuming to solve, i'll skip the factoring or quadratic part:

After done solving the equation, you'll get t = 0.375 and 3.5 seconds. These solutions are valid since both are positive values and time can only be positive.
Hence, it'll take 0.375 and 3.5 seconds for a ball to reach 27 feet.
Area= bh/2
2/5 = (b(6/5))/2
4/5 = b(6/5)
4/6 = b
The answers are:
P ' = (-4,-7)
Q ' = (-8,-7)
R ' = (-3,3)
------------------------------------------------------------------------------------
All you do is swap the x and y coordinates of the given points P, Q and R
The general rule is (x,y) ---> (y,x)
So that's why something like P = (-7,-4) becomes P ' = (-4,-7) when we reflect over the line y = x. The other points are handled the same way.
