This is how I would do it;
Convert to minutes 3/5 *60 = 36
Convert this to decimal 2/5 = 0.4
Then;
if it takes 36 mnts to paint 0.4yd^
in 60 mnts x yd^
___________________
60 x 0.4 / 36 = 0.66666667
convert back to fraction = 2/3 yd^ in 1hr
Answer:
about 28
Step-by-step explanation:
<span>they appear to be using the (2x) as the variable;
so,
</span><span>e^(t) + t^2 ;
now fill in the interval [0,2x]
e^(2x) + (2x)^2 -e^(0)
D{t} [e(2x) +4x^2 - 1]
2e^(2x) + 8x</span>
Answer:
32
Step-by-step explanation:
f(x)= 3(x-2)² + 5
Let x = -1
f(-1)= 3(-1-2)² + 5
Parentheses first
f(-1) = 3(-3)^2 +5
Exponents
f(-1)= 3*9 + 5
Multiply
f(-1) = 27+5
Add
f(-1) = 32
