Answer:
C
Step-by-step explanation:
First, let us try the first on:
sqrt (5^2+4^2)=sqrt 41 so it can't be A
Second one:
sqrt (6^2+7^2)=sqrt 85, no
Third one:
sqrt (8^2+6^2)=sqrt 100 = 10, so it is C
Answer:
in one angle there is 90 degres
Since 8 students take both, that leaves only 4 students who take Algebra I alone.
Likewise since 8 students take both, that leaves 10 who only take Algebra 2
So out of the 60, twenty two are taking either Alg I Alg Ii or both.
That leaves 38 people who are not taking either.
b. 38
You can set this up using a 2 circle venn diagram. Just be sure to put the 8 who take both in first.
This function is a quadratic whose coefficients are a=0.06, b= -7.2, c = 390.
Because a is +, the graph is a parabola that opens up and has a minimum. Your job is to find the value of b at this minimum (at the vertex). It is
b = -(-7.2) / [2(0.06)], or b = 60.
Production costs will be minimized if the number of bats made is 60.
