The correct answer to the question above is (c.) are. The verb "are" agrees with its subject in the sentence above that says: "Your friends or their guest ARE cooking meal." That is because cooking is present and the friends and the guests are plural.
25 times 18 times 6 would be best
For this answer you will have to use the order of operations, aka PEMDAS.
P-Parenthesis
E-Exponents
M-Multiplication
D-Division
A-Addition
S-Subtraction
This is a very easy question because there aren't any exponents.
We can first look at the Parenthesis because that is what comes first in PEMDAS.
(17+5) All we have to do is 17+5= 22
Then we can do multiplication...
so we have 22 times .5 which equals 11.
Lastly, we will do subtraction because there is no addition....
50-11= 39
Our answer will be 39.
multiply total weight by unit cost
8.8 x 2.09 = 17.765 = $17.77
Step-by-step explanation:
Q6
answer A, as x² is the regular parabolic curve up. and x²-3 just shifts this curve down by 3 units. and that is what we need, as the extreme point of the curve is a bit below the x-axis, and therefore has a negative y value.
Q7
answer C, as this curve is the complete opposite of the curve in Q6.
it is the regular parabolic curve but down. that means -x².
but the extreme point is a bit above the x-axis (and has therefore a positive y value). -x²+3 shifts the parabolic curve up by 3 units.
Q8
answer A again. the functional values are only positive (the whole curve is above the x-axis). so, C and D are therefore wrong.
and between A and B we need to remember, that a negative exponent means 1/...
in case of B 1/(2^x).
and that would mean for large positive x we would get very small values for y.
but we see the opposite. for large x we also get large y.
so, it is 2^x (answer A).
