tina solved a quadratic equation and found the solution to be -3/2 and 6 which of the following is equivalent to the quadratic equations that tina solved
Answer:
[tex]x^2-\dfrac{9}{2}x-9=0[/tex]
Step-by-step explanation:
The solutions of a quadratic equation are :
x = -3/2 and x = 6
or we can write it as :
[tex]x+\dfrac{3}{2}=0\ and\ x-6=0\\\\(x+\dfrac{3}{2})(x-6)=0[/tex]
Multiplying both values,
[tex](x+\dfrac{3}{2})(x-6)=0\\\\x^2-6x+\dfrac{3}{2}x-9=0\\\\x^2-\dfrac{9}{2}x-9=0[/tex]
Hence, the required quadratic equation is [tex]x^2-\dfrac{9}{2}x-9=0[/tex].

What is a Geometric progression?If in a sequence of terms, each succeeding term is generated by multiplying each preceding term with a constant value, then the series is referred to as a geometric progression. (GP), while the constant value is called the common ratio.
Conclusion: The nth term from the end of the GP with the last term l and common ratio r = l/ [r(n – 1)]. The sum of infinite, i.e. the sum of a GP with infinite terms is S∞= a/(1 – r) such that 0 < r < 1.
[tex]a_{n}[/tex] = 5[tex](3/4)^{n}[/tex]
[tex]S_{n}[/tex]= Σ[tex]a_{n}[/tex]
[tex]S_{n}[/tex] = ∑5[tex](3/4)^{n}[/tex]
= 5∑[tex](3/4)^{n}[/tex]
= 5 [ 3/4 + [tex](3/4)^{2}[/tex] + ......+ [tex](3/4)^{n}[/tex]]
=5 [ 3/4 * { 1- [tex](3/4)^{n}[/tex]} / 1 - 3/4 ]

The two circles shown above have radii of 8 in. and 2 in.
Answer:
1/4
Step-by-step explanation:
For the first circle 2 x 2in = 4 to find diameter
4 x 3.14 = 12.56
6in x 2 = 12
12 x 3.14 = 37.68
simplify
12.56/37.68
6.28/18.84
3.14/9.42
So the answer is 1/4 since 3.14 x 2 = 6.28
Also since the radius is 2 times longer
Answer:
D
Step-by-step explanation:
Circumference = 2 * pi * r
Circle A / Circle B = 2 * pi * 8 / 2 * pi * 2
You need to take note of the right side. The 2s cancel and so does pi
Circle A/ Circle B = 8/2
Circle A / Circle B = 4/1 = 4

Answer:
x = (1/4) +(1/8)e^2
Step-by-step explanation:
Undo what is done to x.
4ln(8x-2) +2 = 10
4ln(8x -2) = 8 . . . . . . . subtract 2
ln(8x -2) = 2 . . . . . . . . divide by 4
8x -2 = e^2 . . . . . . . . . take antilogs
8x = 2 +e^2 . . . . . . . . add 2

[tex]\\q\leq -4[/tex]
Step-by-step explanation:
I think what you're missing here is that there is a negative sign in front of the q. This means that whatever number you put in for q will be multiplied by negative 1. Positive numbers will become negative, and negative numbers will become positive.
If you substitute 9 for q you will get [tex]-9\geq 4[/tex], which is clearly not true, because -9 is way less than 4.
For writing the equation you divide both sides by -1. When you do this however, you must flip the inequality sign
[tex]-q\geq 4\\q\leq -4[/tex]
the > sign turned into <, and the q and 4 switched signs.

Which function is shown in the graph below? On a coordinate plane, a function is shown. The curve starts in quadrant 4 and curves up to quadrant 1. It goes through (0.5, negative 0.4), (1, 0), and (6, 1). y = log Subscript one-sixth Baseline x y = log Subscript 0.5 Baseline x y = log Subscript 1 Baseline x y = log Subscript 6 Baseline x
Answer:
c
Step-by-step explanation:
The y-values of the graph increases as the value of x increases, which
indicates that a characteristic of the base of the logarithm function.
Correct response:
The function that corresponds with the graph is; [tex]\underline{\mathrm{y = log_6 x}}[/tex]How can the function of a log graph be determined?The given points on the graph are;
The point where the graph starts = Quadrant 4
Direction of the graph = From quadrant 4 to quadrant 1
Points on the graph are;
(0.5, -0.4), (1, 0), and (6, 1)
The given options are;
[tex]y = \mathrm{log_{\frac{1}{6} } x}[/tex]
[tex]y = \mathrm{log_{0.5} x}[/tex]
[tex]y = \mathrm{log_1 x}[/tex]
[tex]y = \mathrm{log_{6} x}[/tex]
From the shape of the graph, in which, log x increases as x increases, therefore;
The base, b, of the logarithm is larger than 1, given that we have;
[tex]\mathbf{log_bx} = y[/tex]
[tex]\mathbf{b^y} = x[/tex]
From the given coordinate points, x increases as y increases, therefore;
b > 1
The possibly option is therefore, y = log₆x
Verifying, we have;
At x = -0.4, y = 0.5
[tex]b^y = x[/tex]
[tex]6 ^{(-0.4)}[/tex] ≈ 0.488
Therefore, the point (0.5, -0.4) is close to the graph of y = log₆x
At the point (1, 0), we have;
6⁰ = 1
Therefore, the point (1, 0), is on the graph of y = log₆x
At the point (6, 1), we have;
6¹ = 6
Therefore, the point (6, 1) is on the graph of y = log₆x
The function of the graph is therefore;

If the radius of a cylinder is 3 centimeters, then the area of one of the circular bases is 18.84 square centimeters. True False
Answer:
false
Step-by-step explanation:
Answer:
False
Step-by-step explanation:
To calculate the area of a circle you need to multiply the radius by itself, then multiply that number by [tex]\pi[/tex].
In this case, our radius is 3, so we multiply 3 × 3 × [tex]\pi[/tex] (which can be estimated as 3.14)
3×3 is 9
9×3.14 is 28.26
28.26≠18.84
So, the correct answer is false. Hope this helps ^.^

what is the sum of 5/12 and 4/9
Answer: 31/36
Step-by-step explanation:Add them up..5/12+4/5 you need to convert to a common denominator. Common denominator is 36; 15/36+16/36=31/36
Answer:
[tex]\frac{31}{36}[/tex]
Step-by-step explanation:
To get the sum you have to have the same denominator.
So you have to find out what can 12 and 9 go into without leaving a remainder which is 36.
Then you divide 36 by 12= 3 and 36 by 9= 4
Then you multiply 3 by 5= 15 and 4 by 4= 16
You add then up and you get 31
So 31/36 is the answer.
