H=14 for this particular instance so:
14=2+29t-16t²
14-2=2-2+29t-16t²
12=29t-16t²
0=-16t²+29t-12
that's as factored as possible so you should use the quadratic formula for the rest and check for extraneous answers
Answer:
Therefore,the level of paint is rising when the bucket starts to overflow at a rate 
cm per minute.
Step-by-step explanation:
Given that, at a rate 4 cm³ per minute,a cylinder bucket is being filled with paint
It means the change of volume of paint in the cylinder is 4 cm³ per minutes.
i.e 
cm³ per minutes.
The radius of the cylinder is 20 cm which is constant with respect to time.
But the level of paint is rising with respect to time.
Let the level of paint be h at a time t.
The volume of the paint at a time t is
Differentiating with respect to t
Now putting the value of 
To find the rate of the level of paint is rising when the bucket starts to overflow i.e at the instant h= 70 cm.
Therefore, the level of paint is rising when the bucket starts to overflow at a rate cm per minute.
Answer:
Can we get a picture please
Step-by-step explanation:
No problem, that's why Brainly exists! :)
Karen is right, as every equilateral triangle has equal angles. The angles in every triangle must add up to 180°, and if all the angles are equal in an equilateral triangle, that must mean each angle is 60°. (180 ÷ 3 (because three sides in a triangle) = 60). Anything under 90° is acute, that means Karen is right because 60 < 90, and is therefore acute.
First we make the fractions homonym ( they must have the same denomitator)
0.6 = 6 / 10 7/9
6/10 = 6 * 9 / 10 * 9 = 54 / 90 7/9 = 7 * 10 / 9 * 10 = 70 / 90
The numbers which are between these numbers are ;
55 / 90 , 56 / 90 , 57 / 90 , 58 / 90 , 59 / 90, 60 / 90 , 61 / 90 , 62 / 90 , 63 / 90 , 64 / 90, 67 / 90 , 68 / 90 , 69 / 90
62 / 90 = 62 / 2 / 90 /2 = 31 / 45
So the right answer is B.
Hope that helps :)
