We can factor the equation into:
(x-10)*(x-3)
Therefore the roots are:
X = 10
X = 3

Answer:

Option B and D are correct.

x = 3 and x = 10

Step-by-step explanation:

Given the functions:

f(x) =x^2-13x+30

Split the middle terms:

f(x) =x^2-10x-3x+30

Take out the common factor:

f(x) =x(x-10)-3(x-10)

⇒f(x) =(x-10)(x-3)

To find the zeroes of this function f(x).

Equate f(x) = 0

then;

(x-10)(x-3)=0

By zero product property: if ab=0 then a=0 or b = 0

then;

x-10 = 0 and x-3 = 0

⇒x = 10 and x = 3

Therefore, the zeros of the given function are: x = 10 and 3

10 1/16ft + 8 3/8ft +1/2 ft
Whitepunk [10]

Answer:

18 15/16 ft

Step-by-step explanation:

what is the request here ?

to do the additions and bring all to one summary result of ft ?

I base my answer on this assumption.

10 1/16 = 161/16

8 3/8 = 67/8

1/2 = 1/2

note let's bring everything to 16th, so that we can actually add them.

161/16

67/8 = 134/16

1/2 = 8/16

161/16 + 134/16 + 8/16 = 303/16 = 18 15/16

cross check :

add all whole numbers first, and then add the remaining fractions too (need to bring them to 16th too).

10 + 8 = 18

1/16 + 3/8 + 1/2 = 1/16 + 6/16 + 8/16 = 15/16

together, 18 15/16

yeah, it is the same.

A1,a2,a3....a30-each of these 30 sets has 5 elements.b1,b2,....bn-each of these n sets has 3 elements.union of a1,a2...a30=union
zzz [600]
 the number of elements in the union of the A sets is:5(30)−rAwhere r is the number of repeats.Likewise the number of elements in the B sets is:3n−rB
Each element in the union (in S) is repeated 10 times in A, which means if x was the real number of elements in A (not counting repeats) then 9 out of those 10 should be thrown away, or 9x.  Likewise on the B side, 8x of those elements should be thrown away. so now we have:150−9x=3n−8x⟺150−x=3n⟺50−x3=n
Now, to figure out what x is, we need to use the fact that the union of a group of sets contains every member of each set.  if every element in S is repeated 10 times, that means every element in the union of the A's is repeated 10 times.  This means that:150 /10=15is the number of elements in the the A's without repeats counted (same for the Bs as well).So now we have:50−15 /3=n⟺n=45
