What is the coefficient of the term x^2 when the expression below is simplified? (5x^2-x-1)-(-3x^2-2x-5)
Answer: 8
Step-by-step explanation:
Given:
(5x^2-x-1)-(-3x^2-2x-5)
Rewrite:
(5x² -x -1) - (-3x² -2x -5)
Distribute the negative:
5x² -x -1 + 3x² +2x +5
Reorder terms:
5x² + 3x² -x +2x -1 +5
Combine like terms:
8x² + x + 4
The coefficient of the x² term is 8,
8x² + x + 4

Answer:
part: 17 players = 1/4
whole: 68 players in all
percent: 17 players = 25%
Step-by-step explanation:
We'll use p as a variable for the total players, alright?
So, 25% of p usually gets called back.
This season, 17 is 25% of p OR you might say 17 = 1/4 of p
in other words, p/4 = 17
multiply each side by 4 (to get the variable alone)
p = 17 * 4
p = 68
______________
part/whole = percent/100
SUBSTITUTE!
17/68 = 25%
check!
(simplify) 1/4 = 25% true!

Answer: Given that MP \\NS , RS\\PQ and MR =NQ
MRN is a straight line with sum of angles equal to 180⁰ MQN is also a straight line triangle equal to 180⁰
Angle at R + 3 = Angle at Q +2 = 180⁰
Angle R is alternate to Q and angle 2 is alternate to 3 and both sets are equal
Therefore angle 1 is equal to 4 and this makes their third angles in the triangle equal.
Triangle MQP then becomes a perfect replica of NRS

Answer:
r=10%
I=1149.60
P=2874
t=(I×100)/(p×r)
(1149.60×100)/(2874×10)

Step-by-step explanation:
We start with our equation that the change of base formula was applied to:
[tex]\frac{log\frac{1}{4} }{log12}[/tex]
The change of base formula describes taking the base (b) of the logarithm and setting it as the denominator while taking the remaining number (a) and setting that as the numerator.
If we reverse the formula, we end up with the supplied answer.

Bella is building two wigwams for a school project on american indian tribes. she first builds two wooden frames, each in the shape of a cone with a base radius of 2 feet and a slant height of 5 feet. if bella wants to cover the frames in fabric, how many square feet of fabric will she need? (use 3.14 for pi and round to the nearest whole number. recall the formulas l a = pi r l and s a = pi r l pi r squared.) square inches
The amount of fabric needed = 2(surface area of the cone-shaped wooden frame) = 88 ft².
What is the surface Area of a Cone?Surface area of a cone = πr² + πrl
Given the following dimensions of the cone-shaped wooden frame:
Slant height (l) = 5 feetRadius (r) = 2 feetAmount of fabric needed = 2(surface area of the cone-shaped wooden frame) = 2(πr² + πrl)

In this problem you will compare the effects of different compounding periods on the interest an investment earns. Complete the table below using the values indicated. Show the formula you used, with the correct values, in the second column. In the third column, give the result, rounded to the nearest cent.
Principal: $1,000
APR: 4.5%
Time: 10 years
Find the equations for annually, quarterly, monthly and daily
Answer:
see attached
Step-by-step explanation:
You are asked to use the compound interest formula for different values of n, the number of times per year the interest is compounded.
__
The basic formula is ...
A = P(1 +r/n)^(nt)
for the amount in an account in which principal P earns interest at annual rate r compounded n times per year for t years.
The problem statement gives values for P, r, t, so we only need to compute the result for different values of n. With the given values filled in, the formula is ...
A = 1000(1 +0.045/n)^(10n)
Values of n to be used are ...
annually: n = 1quarterly: n = 4monthly: n = 12daily: n = 365The formula you will evaluate uses these values where 'n' is in the formula. Corresponding account balances are ...
annual compounding: $1552.97quarterly compounding: $1564.38monthly compounding: $1566.99daily compounding: 1568.27__
For repetitive evaluation of the same formula, we like a calculator or spreadsheet. Many calculators have the "time value of money" formulas pre-programmed. This is shown in the second attachment, where the value that varies is "C/Y", the number of compoundings per year.
