The answer is x^2/3y^3 hopefully this is correct
A) because when they are equal it means that their y has the same value, which means their intersection point.
B) You should take all integers from (-2, 2) which are: -2, -1, 0, 1, 2 and put them one by one in the example:
x = -2
y1 = 4^-(-2) = 4^2 = 16
y2 = 2^(-(-2) + 1) = 2^(2+1) = 2^3 = 8
y1 ≠ y2 => so x=-2 isn't our answer
-------------------------------------------------------
x = -1
y1 = 4^-(-1) = 4^1 = 4
y2 = 2^(-(-1) + 1) = 2^(1+1) = 2^2 = 4
y1 = y2 => so our answer will be x = -1
-------------------------------------------------------
x = 0
y1 = 4^-(0) = 4^0 = 1
y2 = 2^(-(0) + 1) = 2^(0+1) = 2^1 = 2
y1 ≠ y2 => so x=0 isn't our answer
--------------------------------------------------------------
x = 1
y1 = 4^-(1) = 4^(-1) = 1/4
y2 = 2^(-(1) + 1) = 2^(-1+1) = 2^0 = 1
y1 ≠ y2 => so x=1 isn't our answer
--------------------------------------------------------------
x = 2
y1 = 4^-(2) = 4^(-2) = 1/16
y2 = 2^(-(2) + 1) = 2^(-2+1) = 2^(-1) = 1/2
y1 ≠ y2 => so x=2 isn't our answer
Which means that our final answer is: x=-1
C) You should draw both graphics, and their intersection point (x) will be the answer.
I hope it helped.
Answer: 2√10 - √30
explanation:
ok so they’re asking for the difference between the lengths of the sides of each cube. they have different SA’s (surface areas). all you gotta do is plug in the SA in the given equation to find the length of the side and THEN you subtract the answers and thats how you find the difference between the sides.
given:
s = √(SA/6)
SA1 = 240 m^2
SA2 = 180 m^2
S1 = √(240/6) = 2√10 or 6.32
S2 = √(180/6) = √30 or 5.47
s1 -s2 = 2√10 - √30
<span>Students could also give the answers as green to blue, blue to green, truck , car to truck, blue to total, and green to total.Some students may write part to part ratios. When the class comes back together, this could be a good time to discuss why a part to whole ratio is more useful when comparing statements that include percents. Students may need to be reminded that percents are a form of a part to whole comparison where the whole is 100.hoose different pairs of small groups to post diagrams and explain how the diagram helped them to see the relationship between the fractions, percents, and decimals.</span>
Answer:
The cost of the 7.5 lbs of walnuts be $2.16 .
Step-by-step explanation:
As given
It costs $3.45 to buy lb of chopped walnuts.
i.e
Now calculate the cost of one pound .
Now calculated the cost of the 7.5 lbs of walnuts .
Cost of 7.5 lbs of walnuts = 7.5 × 0.2875
= $2.16 (Approx)
Therefore the cost of the 7.5 lbs of walnuts be $2.16 .
