The main idea is using the Pythagorean formula to find the length of line segment 
.
Alr so you use the formula 
is already given and is 
and 
is 
So using algebraic rules you'll get 
as:
Now using the formula: 
, you can find the area of tri ABD and CBD which would be 
and 
so add them up and you get 
!
Answer:
400
Step-by-step explanation:
Looking at the number 433, we have to look at the number in the tens place (in this case, 3) to determine if we will round down to 400, or up to 500.
Because the number 3 is less than 5, we will round down to 400.
4$-20%
X$-100%
X=4·100:20=400:20=20
Answer : He paid for the meal 20$.
Answer:
1760 Hz
Explanation:
The equation for the displacement has the following general formula:
d = A sin(wt)
where:
A is the amplitude
w is the angular frequency
the given equation is:
d = 0.6 sin(3520πt)
We can note that:
w = 3520 π rad/sec
Now,
w = 2πf where f is the frequency
Therefore:
3520π = 2π*frequency
This means that:
frequency = 1760 Hz
Hope this helps :)
