I) HCF - use the smallest powers of each common factors
HCF (A,B) = 2^2 × 3^4 × 5^2
LCM - use the highest powers of each factors
LCM (A,B) = 2^4 × 3^6 × 5^2 × 7^2 × 11^16
ii) Add powers together.
A×B = 2^6 × 3^10 × 5^4 × 7^2 × 11^16
sqrt(A × B)
Divide powers by 2.
sqrt(A × B) = 2^3 × 3^5 × 5^2 × 7 × 11^8
iii) C = 3^7 × 5^2 × 7
Ck = (3^7 × 5^2 × 7) × k
B/c Ck should be a product that is a perfect cube, the powers of the products should be divisible by 3.
(3^7 × 5^2 × 7) × k = 3^9 × 5^3 × 7^3
k = (3^9 × 5^3 × 7^3) / (3^7 × 5^2 × 7)
k = 3^(9-7) × 5^(3-2) × 7^(3-1)
k = 3^2 × 5 × 7^2
Answer:
Step 3 is only wrong
<em>This</em><em> </em><em>is</em><em> </em><em>because</em><em> </em><em>the</em><em> </em><em>symbol</em><em> </em><em>changes</em><em> </em><em>when</em><em> </em><em>writing</em><em> </em><em>in</em><em> </em><em>a</em><em> </em><em>equation</em>
<em>Hope</em><em> </em><em>this is</em><em> </em><em>correct and</em><em> </em><em>helpful</em><em> </em>
HAVE A GOOD DAY!
Answer:7.36
Step-by-step explanation:This one is pretty easy. Add 4.75 to 1.65 which is 6.4 also 6.40. You can make a porportion out of it. 15/100=x/6.40. That way then you'll do
100x=69
96/100
0.96
so, with the meal it will = 7.36
Calculus 1?
To find concavity you must take the second derivative.
As you would to find your local maximums and minimums (critical points) in the first derivative by setting y' = 0, to find points of inflection you set acceleration, y" = 0.
Now that you know where the point in which the function is neither concave up or concave down (at the points of inflection) plug x-values between them into the second derivative for x. If y" is positive between those particular points will be concave up and if y" is negative it will be concave down between that interval.
For a better understanding you might find a good video on Youtube explaining this if you search "Points of Inflections" or "Concavity of a function".
Cheers.
