Solve 6x2 – 2x + 1 = 0) using the Quadratic Formula.
Answer:
decimal form
x = 6.5
exact form
x = 13/2
mixed number form
x = 6 1/2
For the given quadratic equation 6x² – 2x + 1 = 0, the value of x will be 1/6+i√5/6 and 1/6-i√5/6.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation. The quadratic formula, using square roots, factoring, and completing the square are the four ways to solve a quadratic equation.
It is given that the quadratic equation is,
6x² – 2x + 1 = 0
Apply arithmetic operations in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
[tex]x_{1,\:2}=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\cdot \:6\cdot \:1}}{2\cdot \:6} \\\\\ \\\ x_{1,\:2}=\frac{-\left(-2\right)\pm \:2\sqrt{5}i}{2\cdot \:6} \\\\\\\ x_1=\frac{-\left(-2\right)+2\sqrt{5}i}{2\cdot \:6},\:x_2=\frac{-\left(-2\right)-2\sqrt{5}i}{2\cdot \:6}\\\ \\\\x=\frac{1}{6}+i\frac{\sqrt{5}}{6},\:x=\frac{1}{6}-i\frac{\sqrt{5}}{6}[/tex]
Thus, for the given quadratic equation 6x² – 2x + 1 = 0, the value of x will be 1/6+i√5/6 and 1/6-i√5/6.

Camilla is creating gift baskets with scented soaps and bottles of bubble bath. She has 20 scented soaps and 15 bottles of bubble bath. If she wants all the gift baskets identical without any items left over, what is the greatest number of gift baskets Camilla can make?
Answer:
5 gift baskets
Step-by-step explanation:
We solve this question using the method of Greatest Common Factor
We are told in the question that She has 20 scented soaps and 15 bottles of bubble bath
Hence, we find the factors of 15 and 20
The factors of 15 are: 1, 3, 5, 15
The factors of 20 are: 1, 2, 4, 5, 10, 20
Then the greatest common factor is 5.
Hence, the greatest number of gift baskets Camilla can make is 5 gift baskets
A car travels at a constant speed of 58 miles per hour. Which equation can be used to find m, the total number of miles the car travels, in h hours?
Answer:
58xH=M
Step-by-step explanation:
here is an example car traveles 58mph how many miles in 3 hours
58x3=174mph
The required equation that represents the number of miles the car traveled in h hours is m = 58h.
Given that,
A car travels at a constant speed of 58 miles per hour. Which equation can be used to find m, the total number of miles the car travels, in h hours is to be determined.
Distance is defined as the object traveling at a particular speed in time from one point to another.
Here,
As, per the question,
Distance = speed × time
From the given,
Distance = m
Speed = 58 mile / hour
Time = h (in hours)
So,
m = 58 × h
m = 58h
Thus, the required equation that represents the number of miles the car traveled in h hours is m = 58h.

Jeremy bought a $60 pair of sneakers on sale for 15% off. Then, he used a coupon that gave him an additional 10% off. Can Jeremy find the cost of the sneakers by adding the percents? Why or why not?
Answer:
Jeremy find the cost of the sneakers by solving for the values of the 10% in dollars and subtracting the dollar amount from the cost of the sneaker
Step-by-step explanation:
Step one:
given data
cost of sneakers= $60
Required
the cost of the sneaker after the two discounts
Actually, the two percents given are the discount of the sale.
the first discount is
15%= 15/100*60
=0.15*60
=$9
The second is 10% coupon
10/100*60
=0.1*60
=$6
The total discounts = 9+6= $15
The cost of the sneakers= 60-15= $45
Jeremy find the cost of the sneakers by solving for the values of the 10% in dollars and subtracting the dollar amount from the cost of the sneaker
which function is equivalent to h(x)=10x^(2+9x-1)
Answer:
h(x) = (10x - 1)(x + 1)
Step-by-step explanation:
Given
h(x) = 10x²+9x-1
Required
Get its equivalent
To do this, we simply factorize h(x)
We have that:
h(x) = 10x²+9x-1
Expand
h(x) = 10x² + 10x - x - 1
Factorize
h(x) = 10x(x + 1) -1(x + 1)
This gives:
h(x) = (10x - 1)(x + 1)
Hence, the equivalent of h(x) = 10x²+9x-1 is h(x) = (10x - 1)(x + 1)
Answer: h(x) = (x+1) (10x-1)

Answer:
Step-by-step explanation:
let each angle=A
A+A+A=180
3A=180
A=180/3=60°
as the angles are equal so sides are equal.
16+y=46
y=46-16=30
applying sine formula
[tex]\frac{30}{sin z} =\frac{46}{sin~80} \\sin~z=\frac{30}{46} \times ~sin~80=\frac{15}{23} \times sin ~80\\z=sin^{-1}( \frac{15}{23} \times sin ~80) \approx~39.96^\circ \approx40^\circ[/tex]
z+x=60
40+x=60
x=60-40=20°

A roller skating rink charges a flat rate of $5 to rent skates, plus $2.50 per hour to skate. You rent skates and skate for 3 hours. If you pay with a $20.00 bill, how much change do you get back?
Answer:
$7.50
Step-by-step explanation:
First, you multiply 3 and $2.50 (because you skate for 3 hours and it's $2.50 per HOUR to skate) 3 x 2.50 is $7.50 plus the flat rate of $5 is $12.50. So, your total altogether would be $12.50. So if you pay that total with $20, you have to subtract 12.50 from 20. 20 - 12.50 is $7.50. Your change will be $7.50. I hope this is correct! So sorry if it isn't!
Answer:
7.5
Step-by-step explanation:
First, you multiply 2.50 x 3. The answer to that is 7.50. Add on the renting skates, that is 12.50. Then, you subtract 12.50 from 20.00. The answer is 7.5.

Jerry gets price quotes from two different pool cleaning services for the cost of cleaning the pool. Company A charges $7 plus an additional $3 per hour. Company B charges $10 plus an additional $2 per hour. The total price quote for each company is the same amount. How many hours do the companies estimate it will take to clean the pool?
Answer:
3 hoursStep-by-step explanation:
Step one:
given data
price quotes from Company A
charges= $7
additional charges per hour= $3
let the number of hours be x
and the total be y
the linear function for the total is
y=3x+7
price quotes from Company B
charges= $10
additional charges per hour= $2
let the number of hours be x
and the total be y
the linear function for the total is
y=2x+10
if the total quote is the same , then
3x+7=2x+10
solve for x, collect like terms
3x-2x=10-7
x=3 hours

Enter your answers in alphabetical order.
Answer:
The additional information to show ΔABC ≅ ΔDEF by ASA is [tex]\overline {AB}[/tex] ≅ [tex]\overline {DE}[/tex]
Step-by-step explanation:
The given parameters in the figure are;
Angle m∠BAC is congruent to angle m∠FDE
Angle m∠ABC is congruent to angle m∠FED
Therefore, in order to show that ΔABC is congruent to ΔDEF, by the Angle-Side-Angle (ASA) rule of congruency, the additional information is the congruency of the included sides between the given angles as follows;
The additional information to show ΔABC ≅ ΔDEF by ASA is [tex]\overline {AB}[/tex] is congruent to [tex]\overline {DE}[/tex] which can be written as [tex]\overline {AB}[/tex] ≅ [tex]\overline {DE}[/tex].
