often denotes an angle, where
is conventionally used.
Adding
, where
is any integer, is the same as saying that
is equivalent to
etc.
This is the case because a complete revolution has an angle measure of
, which means that adding any multiple of
to a given angle results in the same angle.
Example:
If
, then
. This is also true if
, which gives
.
(13 * 17) /2 = 110.5
Explanation: b * h / 2
Answer:
sin75º=sin(30)º+45º)
=sin 30 cos 45+cos 30 sin 45
=1/2*√2/2+√3/2*√2/2
=√2/4+√6/4
=(√2+√6)/4
Check with calculator:
sin 75º≈0.9659
exact value=(√2+√6)/4≈0.9659
Here in an idea:
lets say his total is repreented with the variable t.
lets say the number of bags of apples is represented by a.
t = a + 2
unless there is missing info.
hope this helps!
Answer:
31.9secs
6,183.3m
Step-by-step explanation:
Given the equation that models the height expressed as;
h(t ) = -4.9t²+313t+269
At the the max g=height, the velocity is zero
dh/dt = 0
dh/dt = -9,8t+313
0 = -9.8t + 313
9.8t = 313
t = 313/9.8
t = 31.94secs
Hence it takes the rocket 31.9secs to reach the max height
Get the max height
Recall that h(t ) = -4.9t²+313t+269
h(31.9) = -4.9(31.9)²+313(31.9)+269
h(31.9) = -4,070.44+9,984.7+269
h(31.9) = 6,183.3m
Hence the maximum height reached is 6,183.3m
