As we know that
Fx = Fcos30.0deg
<span>60.0N = Fcos30.0deg </span>
<span>F = 60.0N/cos30.0deg </span>
<span>F = 69.3 N
</span><span> Fy = Fsin30.0deg </span>
<span>Fy = 69.3 N sin 30.0 deg </span>
<span>Fy = 34.6 N
</span>hope it helps

Step-by-step explanation:
tan θ=−4/7, and 270°<θ<360°
θ is in 4th quadrant
sec θ = 8.06 / 7 = 1.15

Step-by-step explanation:
Let X the random variable that represent the lenght time it takes to find a parking space at 9AM of a population, and for this case we know the distribution for X is given by:
Where
and
For this part we want to find a value a, such that we satisfy this condition:
(a)
(b)
As we can see on the figure attached the z value that satisfy the condition with 0.7 of the area on the left and 0.3 of the area on the right it's z=0.524
If we use condition (b) from previous we have this:
But we know which value of z satisfy the previous equation so then we can do this:
And if we solve for a we got
