x^2-12x-6=-65 solve for x
Answer:
x
Step-by-step explanation:
x
Answer:
x = 6 + 4.796i and x = 6 - 4.796i
Step-by-step explanation:
For this problem, we will simply apply the quadratic formula to find the values of x. The quadratic formula is as follows:
x = [-b +/- sqrt(b^2 - 4ac)] / 2a
Using the formula let's find the values of x.
x^2 - 12x - 6 = -65
x^2 - 12x - 6 + 65 = -65 + 65
x^2 - 12x + 59 = 0
The coefficient of x^2 is a, the coefficient of x is b, and the constant 59 is c.
Hence, for our formula we have the following values:
a = 1
b = -12
c = 59
x = [-b +/- sqrt(b^2 - 4ac)] / 2a
x = [-(-12) +/- sqrt( (-12)^2 - 4(1)(59) ) ] / 2(1)
x = [ 12 +/- sqrt ( 144 - 236 ) ] / 2
x = [ 12 +/- sqrt ( -92 ) ] / 2
x = [ 12 +/- sqrt ( -4 * 23 ) ] / 2
x = [ 12 +/- 2i sqrt(23) ] / 2
x = 6 +/- i sqrt(23)
Hence from the formula, we have two possible values for x, both complex solutions. Note, i is an imaginary number.
x = 6 + i sqrt(23) and x = 6 - i sqrt(23)
x = 6 + 4.796i and x = 6 - 4.796i

The radius of a circles is 5.24 ft. Determine the circumference of the circle.
Answer:
32,82 ft
Step-by-step explanation:
The formula for the circumference of a circle of radius r is C = 2πr.
In this case the circumference is C = 2π(5.24 ft), or approximately
32,82 ft

Zoé compró 3 quesos de 3/5 cada uno. ¿cuántos Kilogramos de queso tiene en total?
Answer:
W = 1.8 kg
Step-by-step explanation:
Zoé bought 3 cheeses, 3/5 each. How many Kilograms of cheese does he have in total?
Weight of each cheese is 3/5 kg. Zoe bought 3 cheeses. We need to find the weight of cheese in total.
To find weight of 3 cheeses, we will multiply 3 by 3/5 such that:
[tex]W=3\times \dfrac{3}{5}\\\\W=1.8\ kg[/tex]
So, the weight of cheese in total is 1.8 kg.
Logan earned $8
for each dog he walked last summer. This summer, he raised his fee to $9
per dog. Express the change in Logan’s fees as a percent. Round to the nearest tenth of a percent
Answer: 11.11%
Step-by-step explanation: Since he earned 8 dollars for each dog last summer, and he now raised it to 9 dollars per dog, we can make the subtract 9/9 - 8/9, which would equal 1/9. 1 is 11.111% of 9, so that's the answer.
What are the two question that you want to ask to clarify the process of translating real life situation to rational function
Answer and Step-by-step explanation:
The rational function is the function that can be written in terms of ratio that contains two polynomial functions in which the denominator is not equivalent to zero
Now the two questions that should be asked which are as follows:
1. Translate real life to rational functions.
2. Process for translate to real life to rational functions
These two questions should be asked
The two question that I want to ask to clarify the process of translating real life situation to rational function are
How can I tell if a function is rational or not?How do rational functions apply in real life situationFor better understanding, lets explain what rational function means.
Rational function is simply known to be the function of the form f(x)= p(x)/q(x) where p(x) and q(x) are polynomial and q(x) cannot equal zero or simply say it is a function gotten when we divides one polynomial by another. in real life, rational functions are often used in modeling more complex equations in science and engineering.From the above we can therefore say that the answer The two question that I want to ask to clarify the process of translating real life situation to rational function are

Whats x solve 1/3x-2/3=-18
Answer:
[tex]x=-52[/tex]
Step-by-step explanation:
multiple everything by 3 to get rid of the fractions
[tex]3(1/3x-2/3=-18)\\1x-2=-54\\[/tex]
rewrite
[tex]x-2=-54[/tex]
add 2 to both sides
[tex]x-2+2=-54+2\\x=-52[/tex]
Answer:
[tex]x=-52[/tex]
Step-by-step explanation:
[tex]\frac{1}{3} x-\frac{2}{3} =-18[/tex]
Add [tex]\frac{2}{3}[/tex] to both sides of the equation:
[tex]\frac{1}{3} x=-18 +\frac{2}{3}[/tex]
Simplify [tex]-18+\frac{2}{3}[/tex] by multiplying [tex]-18[/tex] in fraction form [tex]-\frac{18}{1}[/tex] to get a common denominator so you can add the two fractions:
[tex]-\frac{18}{1}[/tex] × [tex]\frac{3}{3}=-\frac{54}{3}[/tex]
Now add the two fractions:
[tex]-\frac{54}{3} +\frac{2}{3} =-\frac{52}{3}[/tex]
Now write the simplified equation:
[tex]\frac{1}{3} x=-\frac{52}{3}[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]\frac{1}{3}[/tex]:
[tex]x=-\frac{52}{3}[/tex] ÷ [tex]\frac{1}{3}[/tex]
Use the reciprocal of the dividend ([tex]\frac{1}{3}[/tex]), and multiply by your divisor:
[tex]x=-\frac{52}{3}[/tex] × [tex]\frac{3}{1}[/tex]
[tex]x=-\frac{156}{3}[/tex]
Simplify the fraction by dividing [tex]-156[/tex] into [tex]3[/tex]:
[tex]x=-52[/tex]
Write the number four hundred thirty-eight million,eight hundred thousand is standard form
Answer:

The number 438 million comes first, so put 438 and then a comma.
The number 800 thousand is next, so put 800 and then a comma.
There is no number for the hundreds, tens, and ones place, so put 000 with no comma after, like this.

Considering the given matrix, it is found that the number of solutions of the system of equations is given by:
B. 1.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
The matrix form of the system can also be written as:
[tex]\left[\begin{array}{cc}1&0\\0&1\end{array}\right]\left[\begin{array}{c}x\\y\end{array}\right] = \left[\begin{array}{c}5\\6\end{array}\right][/tex]

Find the value of P(A) + P(B)?
Train A is traveling at 70 mph to a destination 200 miles away. Train B will leave 20 minutes after train A. Train B will leave from Train A's destination and will head in Train A's direction. If Train B will be going at a speed 32 of Train A's, how long after Train A left will it take before Train B arrives at Train A's starting point? Round your answer to the nearest tenth of an hour
Answer:
The answer is "2.2 h"
Step-by-step explanation:
Speed of Train B:
[tex]= \frac{3}{2} \times 70 \ mph \\\\= 105 \ mph[/tex]
Train B is then moving on:
[tex]= \frac{200 \ miles}{ 105 \ mph} \\\\= 1.905 \ h\\[/tex]
Then it takes Train A to the left:
[tex]\to 1.905\ h + 20 \ min \\\\= 1.905 \ h +0.333 \ h \\\\= 2.238 \ h[/tex]
To get train B to the reference point of train A = 2.2 h

What is Center, Incenter and Circumcenter of the triangle?
Incenter I, whose point is equidistant from the triangle's sides, and circumcenter O, whose point is equidistant from each of the triangle's vertices. A triangle center is a point in the plane that resembles the centers of squares and circles in some ways, meaning that it is roughly in the centers of the figure.
Given: Three towns are linked by three straight roads.
Loretta Adman has created a three-sided billboard that she wants to position as close as possible to all three roads.
