We are given with the rate of change of the base, db/dt equal to 1 ft/ sec and the rate of change of the height of the triangle, dh/dt equal to 2 ft/sec. b is 10 ft and h is 70 ft. Area of triangle is equal to A= 0.5 bh The rate of change of the area is equal to dA/dt = 0.5 b dh/dt + 0.5 h db/dt. Substituting, dA= 0.5*10*2 + 0.5*70 * 1 equal to 45 ft2 / sec.
Answer:
Step-by-step explanation:
Given
For complex roots Discriminant should be zero
D<0
here
so 
so
9 ÷ 12 = 0.75
Let’s check our work: 0.75 x 12 = 9
Therefore, the answer is 0.75

Bad idea.. because the cloth will get hot and then make your water inside warm
Hello!
You can put in y for the first equation
2x - 3(x - 1) = -1
Distribute the -3
2x - 3x + 3 = -1
Combine like terms
-x + 3 = -1
Subtract 3 from both sides
-x = -4
Since x is negative we can multiply both sides by -1 to make x positive
x = 4
We can put x into the second equation to get y
y = 4 - 1
y = 3
The answers are x = 4 and y = 3
Hope this helps!
