What is the value of the coefficient of the 5th term in the expansion of (a + b) ^6
a. 20
b. 6
c. 10
d. 15
Answer:
D. 15
Step-by-step explanation:
I assume you know what pascal's triangle is if this is the work you must complete. If not, I have attached it below.
Now, raising (a+b) to the 6th term would expand to this, based on Pascal's triangle
[tex]\left(a+b\right)^6 = \quad a^6+6a^5b+15a^4b^2+20a^3b^3+15a^2b^4+6ab^5+b^6[/tex]
Remember that terms are separated by addition or subtraction symbols.
The 5th term of this 7 term expansion would be 15a^2b^4. The coeffecient is 15 in this case.

x = –2
5x + 3y = 14
Answer: (-2, 8)
Explanation:
Plug x = -2 into the second equation. Isolate y.
5x+3y = 14
5(-2)+3y = 14
-10+3y = 14
3y = 14+10
3y = 24
y = 24/3
y = 8
We have x = -2 lead to y = 8.
Therefore, the ordered pair (x,y) = (-2,8) is the solution to this system.
Someone please help me! Which one is independent and dependent
Answer:
The top is independent
The bottom is dependent
Step-by-step explanation:
The top is independent because it does not rely on another variable. It is the "affector" and not dependent on it.
The bottom is dependent because it does rely on another variable. It is dependent on this other variable because it will be affected by any changes in that other variable.

By selling a television set for $421 Suzie incurred a loss of 6% . what is the cost price ?
Answer:
The cost price is $395.74 or $446.26
Step-by-step explanation:
When we do 421 times 0.06 (same thing as 6%) we get 25.26
We subtract 25.26 from 421 we get $395.74
If we add 25.26 to 421 we get $446.26

A parabola can be drawn given a focus of (5, -3)and a directrix of x=1. What can be said about the parabola?
Answer:
The parabola is a horizontal parabola and it faces to the right. The vertex is at (3, -3) (*Double check this because I don't have graph paper*) because the vertex is always the same distance from the directrix and the focus.

Number of Years Since 2009
Based on this information, which function best models the number of game consoles sold in
millions x years since 2009?
A 9(x) = 0.6(25.5)
09(x) = 25.5(0.6)
c g(x) - 6.12(25.5)
D 9(x) = 25.516 Y
The graph is an illustration of an exponential function
The equation of the graph is: [tex]y = 25.5 * 0.6^x[/tex]
How to determine the equation of the graphFrom the graph, we have the following ordered pairs
(x,y) = (0, 25.5), (1, 15.3) and (2, 9.18)
An exponential function is represented as:
[tex]y = ab^x[/tex]
When x = 0, we have:
[tex]25.5 = ab^0[/tex]
[tex]a = 25.5[/tex]
When x = 1, we have:
[tex]15.3 = ab^1[/tex]
[tex]15.3 = ab[/tex]
Substitute 25.5 for a
[tex]15.3 = 25.5b\\[/tex]
Solve for b
[tex]b = 0.6[/tex]
So, the exponential equation is:
[tex]y = 25.5 * 0.6^x[/tex]
Hence, the exponential equation of the graph is: [tex]y = 25.5 * 0.6^x[/tex]

g(x) =25.5(0.6)ˣ function best models the number of game consoles sold in millions x years since 2009?
From the given graph we can observe three ordered pairs which are (0, 25.5), (1, 15.3) and (2, 9.18).
We have to find the function which best models the number of game consoles sold in millions x years since 2009.
This we can find by using exponential function.
y=abˣ
When x = 0, we have:
a=25.5
When x=1, then y should be 15.3
15.3=ab
Substitute 25.5 for a
15.3=25.5b
Divide both sides by 25.5:
b=0.6
So the function is g(x)=25.5(0.6)ˣ

Write three rational numbers between −1 /5 and 1 /2
Answer:
-1/10, 2/10, and 4/10
Step-by-step explanation:
A rational number is a number that is in the form of p/q, where p and q are integers, and q is not equal to 0.
First, what is the lcm of 5 and 2? the lcm is 10, because that is the lowest number than can be divided separately by 5 and 2 and the results would still be a whole number.
We now need to find 3 rational numbers between -2/10 and 5/10. It's easy now that I've explained it, right?
-1/10, 2/10, and 4/10 are between -1/5 and 1/2 and are integers with the given explanation.

Are the two triangles similar? Why or why not?
Answer:
(c) Similar by AA~
Step-by-step explanation:
The outside segments are marked parallel, so the angles formed where the transversals meet them are congruent. That is ∠CBD ≅ ∠EDB, and ∠CED ≅ ∠ECB. (The vertical angles where the lines cross are congruent, as well.)
So, the angles in one triangle are congruent to the angles in the other triangle. The triangles are similar by the AA~ postulate.

What is an Algebraic Expression?An algebraic expression involves using numbers and variables to make statements.
Let the unknown number be represented as x. Therefore:
Twice the number is 2x
2x is 500 more than 6x is 2x = 6x + 500
Solve the algebraic equation to find the number (x):
2x = 6x + 500
2x - 6x = 500
-4x = 500
x = -500/4
x = -125
Thus, using algebraic expression, the number is calculated as: -125.
