13. Find PS. 39 Р \76° R 28° S
1 answer:
Answer:
21.38
Step-by-step explanation:
Find the diagram attached
In order to get PS, we need to get the length of QS first
According to triangle QRS;
QS =opposite
QR = 39(adjacent)
Using SOH CAH TOA
Tan theta = opp/adj
Tan 28 = QS/39
QS = 39tan28
QS = 39(0.5317)
QS = 20.74
Get PS
sin theta = QS/PS
sin 76 = 20.74/PS
PS = 20.74/sin76
PS = 20.74/0.9703
PS = 21.38
Hence the length of PS is 21.38

Answer:
An Inverse variation states that a relationship between two variables in which the product is always constant.
If one of the variable increases then the other decreases in proportion so that the product is unchanged.
if y is inversely proportional to x, then the equation is of the form
, where k is constant.
As per the given condition, A constant force acts upon an object, the acceleration of the object varies inversely with it's mass.
i.e,
By definition of inverse variation;
. ......[1] ,where F is the constant force.
It is given that an object has mass(m)= 4kg and the acceleration of an object(a) = 14
Substitute these in [1] to find the constant force F;
or
Now, if the same force acts upon the another object whose mass (m) = 7 kg then calculate acceleration.
[1]⇒
therefore, the acceleration of an another object is,
