2. Which size is the better buy?The family size is the better buy.
Answer:
-63
Step-by-step explanation:
To find the discriminant, you just need to apply the square root part of the quadratic formula:
Sqrt (b^2 - 4ac)
Sqrt (9 - 4 x 1 x 18)
Sqrt (-63)
The number inside of the square root would be the discriminant.
A negative discriminant means that the quadratic would result in imaginary solutions.
We can use SOH CAH TOA to solve this :)
We’re going to use Cosine because the angle and sides given are Adjacent and Hypotenuse- which goes with the CAH part of SOH CAH TOA.
Cos(18) = x/25
Multiply both sides by 25
25cos(18) = X = 23.776
So x = 23.776 cm
I hope this Helps!
Answer:
They had 7,618.8 subscribers last year.
Let me know if this helped :)
Step-by-step explanation:
We need to find 40% of 12,698
To do that, we need to multiply 12,698 by the decimal form of 40%.
12,698*0.40=5,079.2
Then, we need to subtract 5,079.2 from the amount of subscribers we had this year.
12,698-5,079.2= 7,618.8
C. Exactly one unique triangle exists with the given side lengths.
<u>Step-by-step explanation:</u>
A triangle consists of three sides, depending on the measurement of the sides, naming of the triangles can be varied.
If all the three sides are equal in length, it is said to be an equilateral triangle. Only one triangle can be formed using the measures of 7 in, 7 in, 7 in, that is all the three sides are same in measurement of 7 inches.
So, Exactly one unique triangle can be produced with the given side lengths.
