3
Step-by-step explanation:
distance formula
Answer:
A is correct
Step-by-step explanation:
What we need to do here is to multiply all the roots together
The roots are;
3, √5 and -√5
Let’s have them in form of a sum
if x = 3, then the root is x-3
If x = √5, then the root is x-√5
If x = -√5, then the root is x+ √5
Now we need to multiply all these together to arrive at the original polynomial
Let’s start by using the roots
(x-√5)(x+ √5)
we can use the difference of 2 squares here and we arrive at (x^2 -5)
So finally, the polynomial would be;
(x^2-5)(x-3)
= x(x^2-5) -3(x^2-5)
= x^3-5x-3x^2+15
By rearranging, we have;
x^3-3x^2-5x+15
Answer:
3 3/8 cups of flour
Step-by-step explanation:
So, we know that 2 1/4 is the normal amount of flour you would use in the recipe. but you don't want to do normal. You want to make 1 1/2 times more than you usually do.
To do this, first figure out what half of 2 1/4 is.
(2 1/4) /2 = 1 1/8
Then, because you are looking to use 1 1/2 times more flour, simply add the 1 1/8 to the 2 1/4
You end up using 3 3/8 cups of flour.
Answer:
0.63
Step-by-step explanation:
M: The selected dog is a male. P(M) = 24/40 = 0.6
B: The selected dog is a boxer. P(B) = 22/40 = 0.55
M and B: 14/40 = 0.35
P(M/B) = 0.35 / 0.55 = 0.63
The answer is 36 (Don't mind the comment, I forget you could edit the answer)
36 / 4 = 9
36 + 4 = 40
40 / 5 = 8
