The general form of quadratic equation is ax²+bx+c =0,
where x = (-b±√(b²-4ac))/2a
The equation is x²-10x+4.75=0
Here, a=1, b= -10, c=4.75
Hence, x= (10±√(100-19))/2
x=(10+8)/2, x= (10-8)/2
x=9, x=1

Final answer:
The quadratic trinomial x² - 10x + 4.75 is solved using the quadratic formula. The coefficients identified are a=1, b=-10, and c=4.75, and when substituted into the formula, it yields solutions x = 7 and x = 3.
Explanation:
Solving a Quadratic Equation Using the Quadratic Formula
To solve the quadratic trinomial x2−10x + 4.75 using the quadratic formula, 'x' equals minus 'b', plus-or-minus the square root of 'b' squared minus four 'a' 'c', all over two 'a', we first identify the coefficients a, b, and c from the trinomial, which are in the standard form of ax2 + bx + c = 0.
Identifying coefficients: a = 1 (the coefficient of x²), b = -10 (the coefficient of x), c = 4.75 (the constant term).
Plugging the coefficients into the quadratic formula: x = −(-10) ± √((-10)2 − 4(1)(4.75)) / (2(1)).
Calculating the discriminant: Calculate b2 − 4ac which is 100 − 19.
Square root step: Take the square root of the discriminant, which is √81.
Final calculation: Compute the two possible values for x which are x = 5 + √81 / 2 and x = 5 − √81 / 2.
Solution: The roots are x = 5 + 9/2 and x = 5 − 9/2, simplifying to x = 7 and x = 3.
The final answer for the roots of the equation x² − 10x + 4.75 = 0 using the quadratic formula are x = 7 and x = 3.
The circumference of a circle is 80ft. What is the area of the circle? (Rounded to the nearest square foot)
Answer:
A≈509.3ft^2
Step-by-step explanation:
You find the Area of a Circle with formula A=πr^2
Down below is an example of how you can do so.
So for you problem you are given the circumference of the circle divide 80 by 2 to get 40. 40/3.14=12.73...
A=3.14*12.73...^2
12.73*12.73=162.05...
3.14*162.05=508.84...
Rounded off Area = 509.3

Answer:
[tex]\frac{13\pi}{9}[/tex]radian
Step-by-step explanation:
We are given that
[tex]\theta=260^{\circ}[/tex]
We have to convert angle into radian.
We know that
Radian measure=[tex]\frac{\pi}{180}\times degree\;measure[/tex]
Using the formula then we get
Radian measure=[tex]\frac{\pi}{180}\times 260[/tex]
Radian measure=[tex]\frac{13\pi}{9}[/tex]radian
Hence, 260 degree=[tex]\frac{13\pi}{9}[/tex]radian

Answer:
a= 1
b= 3
c= 1
d=2
e= 6
f= 8
Step-by-step explanation:
Plug the x value into the equation above the letter that you solve for.
This would give
a = 2^0 = 1 (since any number to the zero power is 1)
b = 3* 2^0 = 2 (we already know what 2^0 is we just have to multiply it with 3)
c= 2^ (3*0) = 2^0= 1 (when 3x is saying that you multiply the x value by zero then raise 2 to what that equals. any number times zero is zero and any number raised to the zero power is 1.
d= 2^1 = 2 (any number to the first power is that number)
e= 3* 2^1(we already know the value of 2^1 is we just have to multiply it with 3)
f= 2^(3*1)= 2^3 = 8 ( same rules as with c just multiply x, which equals 1 in this case with 3. 1 times any number is that number so you get 3. then raise 2 to the 3rd power which is 8.

Answer
7,0
Step-by-step explanation:
Substitute -6y+7 into problem one where the x is
distribute the 2 and subtract the 9 y and you will get

The second wrestler weighed more at the beginning of the diet and gained weight faster.
Explanation:The first wrestler weighed 95 kilograms at the beginning of the diet, while the second wrestler weighed 101.75 kilograms. Therefore, the second wrestler weighed more at the beginning of the diet. To determine which wrestler gained weight faster, we can compare the rates at which they gained weight. The first wrestler gained 4.5 kilograms in 6 months, while the second wrestler gained 8.75 kilograms in the same time period. Therefore, the second wrestler gained weight faster.

A bag has 24 marbles: 6 green, 6 red, and 12 blue. Lucy reaches in the bag and picks out 1 marble. Answer the following:
What is the total number of marbles?
What is half the total number of marbles?
Name an event that is impossible:
Name an event that is certain:
Name an event that is as likely as not:
Name an event that is more likely than not:
Name an event that is unlikely:
Final answer:
The bag has 24 marbles, with 12 marbles constituting half of the total. An impossible event would be drawing a marble color not present in the bag, while a certain event is the act of drawing a marble itself. A likely event is drawing a blue marble due to its greater number in the bag.
Explanation:
The total number of marbles in the bag is 24 marbles. Half the total number of marbles would be 12 marbles.
An impossible event would be Lucy picking out a marble that is not green, red, or blue since those are the only colors available in the bag.
A certain event is Lucy picking a marble from the bag, as there are marbles to be picked.
An event that is as likely as not is Lucy picking out a red marble since the probability of picking a red marble is 6 out of 24, which simplifies to 1 out of 4.
An event more likely than not is Lucy picking out a blue marble, given there are 12 blue marbles out of 24.
An unlikely event is Lucy picking out a green marble since there are only 6 green marbles out of 24.

Answer:
The volume of a pyramid is 1243.5 cubic inches.
Step-by-step explanation:
Given : A pyramid with a square base, where the side length of the base is 18.5 in and the height of the pyramid is 10.9 in.
To find : The volume of a pyramid ?
Solution :

What is the value of log Subscript 3 Baseline 81?
2

4
5
Answer:
4
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]
Given
[tex]log_{3}[/tex] 81 = n, then
81 = [tex]3^{n}[/tex]
Note that 81 = [tex]3^{4}[/tex] , thus
[tex]3^{4}[/tex] = [tex]3^{n}[/tex]
Since the bases are equal then equate the exponents
n = 4
The value of log Subscript 3 Baseline 81 (i.e Log₃ 81) obtained is 4
Data obtained from the question Log₃ 81 =? How to determine the value of Log₃ 81Let Log₃ 81 be equal to n i.e
Log₃ 81 = n
The value of n can be obtained as follow:
Log₃ 81 = n
81 = 3ⁿ
Express 81 in index form with 3 as the base
3⁴ = 3ⁿ
Cancel out 3
n = 4
From the calculation made above, we can conclude that the value of log Subscript 3 Baseline 81 (i.e Log₃ 81) is 4
