Answer:
21
Step-by-step explanation:
f(x) = 2x^2 + 3
f(-3) = 2(-3)^2 + 3
f(-3) = 2(9) + 3
f(-3) = 18 + 3
f(-3) = 21
Answer:
Step-by-step explanation:
5y + 6y + 7y = 18y......any numbers that add(or subtract) to equal 18, stick them before the y....
or it could be : 10y + 10y - 2y = 18y or 5y + 10y + 3y or 30y - 20y + 8y....I could go on forever...lol
250.6 is your number
The "6" in .6 right after the decimal is the tenths place
So right after the tenths place is the hundredths place
But as you can see in 250.6, there is no hundredths place you can see so it is 0
250.60 is the same as 250.6
So 250.6 is already rounded to the nearest hundredths
Answer:
The derivative of any constant number is 0.
So,
Differentiating with respect to "x",
d f(x)/dx
=d 25/dx
=0
Answer:
Part A: Triangles GCB and PBE
Part B: They're similar because they have the same internal angles.
Part C:
250/400 = BE/450
112500/400 = BE
BE = 281.25 ft
250/400 = PE/350
87500/400 = PE
PE = 218.75 ft
