It's three thousand and fifty
Consider the attached figure. All the triangles shown are similar, so
CB/CA = CD/CB
30/50 = projection/30
projection = 30^2/50
projection = 18
Answer:
1. 10n
2. 3x^2z^2
3. 2(9n^3 - 3n^2 + 3n - 1)
4. (Put the same thing)
5. There are no common factors so it is completely factored out.
Step-by-step explanation:
For 1, you gotta find the gcf of the numbers and the variables. So, the common factor of 90, 70, 70, and -80 is 10. Nothing else greater than 10 divides these numbers. For the variables, only "n" is the GCF, as there is one "n" and all the other numbers have n^2 and etc.
For 2, same thing, you have to find the gcf for the numbers and the variables.
3. same thing ;-; (gcf is 2 btw, nothing divides the variables because 2 has no "n".
4. theres nothing that divides the numbers or the variables. So, the gcf is just 1.
Answer:
214
Step-by-step explanation:
35% of 214= 74.9
=75( rounded to while number)
<h3><u>Question:</u></h3>
f(x) = 3x^2 + 4x – 8.
How many zeros does this have?
<h3><u>Answer:</u></h3>
The given function has two zeros
<h3><u>Solution:</u></h3>
According to the "Fundamental Theorem of Algebra", a polynomial of degree "n" has "n" zeroes
Regardless of odd or even, any polynomial of positive order can have a maximum number of zeros equal to its order. For example, a cubic function can have as many as three zeros, but no more. This is known as the fundamental theorem of algebra.
The degree is the value of the greatest exponent of any term (except the constant ) in the polynomial.
Your function is second degree polynomial, so it has two zeroes.
These can be a mix of rational, irrational, and complex zeroes.
