I think that it is a 50 / 50 chance it will land on head or tails.

( hoped this helped) :)

Proabably. 5 because if there is 2 sides on a coin then you should divide 10÷2 which is 5.

- If the contact time between bat and ball is 3.00 10-3 s, calculate the average force between the ball and bat during contact. ... now that we have dp we divide it by 3 x 10^-3 s. ... therefore the average force ( or impulse) between the ball and the bat during contact is 12000 N.

Use the change of variables s=x+3y, t=y to find the area of the ellipse x2+6xy+10y2≤1.

MArishka [77]

$t=y\implies s=x+3t\implies x=s-3t$

Then

$x^2+6xy+10y^2=(s-3t)^2+6(s-3t)t+10t^2=s^2+t^2\le1$

which is a disk of radius 1, hence with area $\pi$ .

Answer:

x = 54
angle ACD = 124°

Step-by-step explanation:

The rule is that the exterior angle (ACD) is equal to the sum of the remote interior angles (the two marked angles on the right).

You are expected to use this relation to write and solve an equation.

exterior angle = angle D + angle B

(2x +16) = 58 + (x+12)

2x +16 = x +70

x + 16 = 70

x = 54

Then angle ACD is ...

angle ACD = (2x +16)° = (2·54 +16)°

angle ACD = 124°

Ayaan travels 90 miles at an average speed of 60 mph.

lawyer [7]

Step-by-step explanation:

Speed = distance / time

Thereafter,

Distance :-

90 miles + 40 miles = 130 miles

Time :-

90 / 60 + 59 = 60.5 mph

Average Speed :-

130 / 60.5 = 2.148
