The answer is 93 It’s 1209 divided by 13 not 13 divide by 1209 ;) hope this helps ! Because when we’re dividing the number get smaller and when we multiplying the number gets bigger , have a nice day !
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).
Answer:
1.40f
Step-by-step explanation:
Amount of snowfall in February = f cm
1) Amount of snowfall in March = 40% more snowfall than in February
= Amount of snowfall in February + 40% of snowfall in February
= f + 40% of f
2) 40% is converted into decimal as 0.40 and the term 'of' translates to a multiplication mathematically
So, we get
Amount of snowfall in March = f + 0.40*f
3) Simplifying the above expression, we get
f+0.40f
= f (1+0.40) [factor out the f from both the terms]
= f(1.40)
Amount of snowfall in March = 1.40f
T = k/r where k is the constant of variation
substituting:-
6 = k / 5
multiplying both sides by 5:
30 = k
canstant of variation = 30
-6b - 12 + 8
-6b - 4
If b is entered incorrectly and should be -6b - 4. Then the answer is b. Else the answer is none of the above
