Answer:
20 questions
Step-by-step explanation:
Well, 10% of 50 is 5, and 5 x 4 = 20. Another way is 50 x .4
Step-by-step explanation:
yes it is . becoz if you kbow the 5 is to 8 means it is an irrational number
The line that has the steeper slope is line b

Answer: ds/dt = 11</h3>
================================================
Work Shown:
Before we can use derivatives, we need to find the value of s when (x,y) = (15,20)
s^2 = x^2+y^2
s^2 = 15^2+20^2
s^2 = 225+400
s^2 = 625
s = sqrt(625)
s = 25
-----------
Now we can apply the derivative to both sides to get the following. Don't forget to use the chain rule.
s^2 = x^2 + y^2
d/dt[s^2] = d/dt[x^2 + y^2]
d/dt[s^2] = d/dt[x^2] + d/dt[y^2]
2s*ds/dt = 2x*dx/dt + 2y*dy/dt
2(25)*ds/dt = 2(15)*5 + 2(20)*(10)
50*ds/dt = 150 + 400
50*ds/dt = 550
ds/dt = 550/50
ds/dt = 11
-----------
Side note: The information t = 40 is never used. It's just extra info.
The exterior angle is ∠3 and ∠BAC is 78°
Step-by-step explanation:
An exterior angle is one formed by one side of a triangle and extension of an adjacent side of the triangle.The sum of two non-adjacent interior angles will equal the measure of the exterior angle of the triangle.
In finding the value of ∠BAC first find ∠BCA (180°-113°=67°) ⇒sum of angles formed in a straight line add up to 180°
∠BAC= 180°-(∠ABC +∠BCA)⇒sum of angles in a triangle
∠BAC=180°-(35°+67°)
∠BAC=180°-102°=78°
