You just have to plug in each thing:
So f(0):
3(0)^2 - 4 = -4
so its not A
f(-2) and f(2):
3(-2)^2 - 4
3(2)^2 -4
now we don't even have to calculate these, anything to the power of an even number is a positive number so -2^2 and 2^2 both equal 4
B is correct, so you can do the others if you want to check, but if B is true the others shouldn't be true.
Answer:
3.41<u>6</u>, bar above 6
Step-by-step explanation:
41/12 = 3.4166666666666
41/12 = 3 & 5/12
we can conclude that the last digit of the product of all the numbers between 11 and 29 is 0.
<h3>What is the last digit of the product of all the numbers between 11 and 29?</h3>
Here we want to find the last digit of the product between all the whole numbers larger than 11 and smaller than 29.
Then we have the product:
P = 12*13*14*15*16*17*18*19*20*21*22*23*24*25*26*27*28
Now, notice that there is a 20 there.
Any number times 20 will end with a zero, then:
P = 20*(12*13*14*15*16*17*18*19*21*22*23*24*25*26*27*28)
Only with that, we can conclude that the last digit of the product of all the numbers between 11 and 29 is 0.

Answer:
171
Step-by-step explanation:
180 - (5% × 180)
180 - 5% × 180
(1 - 5%) × 180
(100% - 5%) × 180
95% × 180
95 ÷ 100 × 180
95 × 180 ÷ 100
17,100 ÷ 100 = 171.
