Answer:A
Step-by-step explanation:
Quite sure
Step-by-step explanation:
First find the angle BAC
BAC= 180 -(90+50) ( interior angle of triangle is 180)
BAC= 180- 140
= 40 degrees
sin 40= opposite/ hypotaneus
sin 40 = 2/ hyp
0.6427 = 2/ hyp
hypotaneus = 2/ 0.6427
hypotaneus = 3.1118
AB= 3.1118
to nearest hundredth = 3.11
Answer:
(a) i believe it is $10
(b)I believe it is 98 people
Step-by-step explanation:
(a) we are trying to find "?" for this explanation. I came up with the equation 60=6 x ?. The 60 shows us the total amount of dollars that the 6 shares went down. We need to find the amount. of dollars that went down for 1 stock. So we divide 60 by 6. and get 10.
(b) we are trying to find "?" for this explanation. I came up with the equation
?=7 x 14. All you have to so is multiply 7 by 14 and you get 98.
Hope this helps :)
The area of the square increasing at 30 
The rate of change function is defined as the rate at which one quantity is changing with respect to another quantity. In simple terms, in the rate of change, the amount of change in one item is divided by the corresponding amount of change in another
Let the side of a square be x.
So,
Area of square = 
A =
Differentiating with respect to time we get,
dA/dt = 2x dx/dt
When area = 9 
the side becomes 3 cm
At x = 3cm and dx/dt = 5 cm/s (Given)
dA/dt = 2.3.5 = 30
Thus the area of the square increasing at 30
