x^2 - 4x + 3 = 0
Answer:
the answer would be x=3,1
Answer:
After completing the square, we can say:
(x - 2)² = 1
If we solve for x, this tells us that x has a value of both 1 and 3.
Step-by-step explanation:
Given:
x² - 4x + 3 = 0
We can complete the square by adding 1 to both sides:
x² - 4x + 4 = 1
(x - 2)² = 1
We can then solve for x by saying:
(x - 2)² = 1
x - 2 = √1
x = 2 ± 1
x = 1, 3

Students at Garcia Middle School took a survey about their favorite school.The results showed that 182 students rated pizza as their favorite food. This number represented 68% of the number of students who took the survey.What was the total number of students that took the survey?
Answer:
267.64 students
Step-by-step explanation:
Let the total number of students that took the survey be represented as x
This number represented 68% of the number of students who took the survey.
The results showed that 182 students rated pizza as their favorite food.
Therefore:
68% × x = 182 Students
68/100 × x = 182
68x/100 = 182
Cross Multiply
68x = 182 × 100
x = 182 × 100/68
x= 267.64705882 students
Therefore, the total number of students that took the survey is Approximately 267. 64 students

The area of a typical eardrum is about 5.00 10-5 m2. (a) Calculate the average sound power incident on an eardrum at the threshold of pain, which corresponds to an intensity of 1.00 W/m2. 5e-5 Correct: Your answer is correct. W (b) How much energy is transferred to the eardrum exposed to this sound for 4.10 min
Answer:
5 * 10^-5 W
1.23 * 10^-2 J
Step-by-step explanation:
Given that :
Area = 5 * 10^-5 m²
Threshold of Pain = Intensity = 1.00 W/m2
Using the relation:
Intensity = power / Area
Hence,
Power = Intensity * Area
Power = 1 W/m² * 5 * 10^-5 m²
Power = 5 * 10^-5 W
Energy transferred to eardrum. Exposed for 4.10 minutes :
Using the relation :
Energy = Power * time
Energy = 5 * 10^-5 * (4.10 * 60 seconds)
Energy = 5 * 10^-5 W * 246 s
Energy = 0.0123
= 1.23 * 10^-2 J

Step-by-step explanation:
The formula for a area of the first semi circle is
[tex] \frac{1}{2} \times \pi {r}^{2} [/tex]
where r is the radius
Since 4 is the diameter, 2 is the radius
plug it in
[tex] \frac{1}{2} \times \pi {2}^{2} [/tex]
[tex] \frac{1}{2} \times 4\pi[/tex]
[tex]2\pi[/tex]
so the area of the first circle is 2
[tex]2\pi[/tex]
now let find the second circle
Since the semi circle is twice the area of AB the diameter is 8 so the radius is 4.
Put it in the equation.
[tex] \frac{1}{2} \times \pi {4}^{2} [/tex]
[tex] \frac{1}{2} \times \pi \times 16[/tex]
[tex]8\pi[/tex]
Now let find the third circle
Since it is twice the size of the second circle, the diameter is 16 and the radius is 8.
[tex] \frac{1}{2} \times \pi {8}^{2} [/tex]
[tex] \frac{1}{2} \times 64\pi[/tex]
[tex]32\pi[/tex]
Now let add the area of the semi circle
[tex]32\pi + 2\pi + 8\pi = 42\pi[/tex]
At 9AM a train traveling 60 miles per hour leaves Los Angeles for San Francisco, a distance of 400 miles. At noon a car traveling at an average speed of 40 miles per hour leaves San Francisco for Los Angeles. At what time will the two vehicles pass each other?
ANSWER PLS
Answer is in the picture:
At 2:02 PM the two vehicles pass each other.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
Given thta,
Los Angeles to San Francisco:
rate = 60 mph ; distance = x miles ; time = d/r = x/60 hrs
San Francisco to Los Angeles:
rate = 40 mph ; distance = 400-x ; time = d/r = (400-x)/40 hrs
So, equation is
x/60 = (400-x)/40 + 3
x/60 = (400-x)+120/40
40x = 60[(400-x)+120]
40x=24000-60x+7200
100x=31200
x=312 miles
Now, time = 312/60
= 5.2 hours
Clock time = 9+5.2
= 14.2 hours
= 2:02 PM
Therefore, at 2:02 PM the two vehicles pass each other.

Solve the system below.
y = x2
y = –2x + 15
Answer:
since,
y = 2x and y = –2x + 15
then,
2x = –2x + 15
or, 4x = 15
or, x = 15/4
or, x = 3.75
Also,
y= 2x
= 2*3.75
= 7.5
Hope it helped
All the best!!
Answer:
Step-by-step explanation:
[tex]x^{2} = -2x^{2} +15[/tex]
add [tex]2x^{2}[/tex] to both sides
[tex]3x^{2} = 15[/tex]
divide each side by 3
[tex]x^{2} =5[/tex]
square root each side [tex]\sqrt{x^2} =\sqrt{5}[/tex]
[tex]x= 2.23606794[/tex] or rounded to the nearest hundredth [tex]x=2.24[/tex] or x = ±[tex]\sqrt{5}[/tex]

Which of the following statements best compares the maximum value of the two functions?
The maximum value is the same for both functions.
Of(x) has a greater maximum value than g(x).
O g(x) has a greater maximum value than f(x).
The maximum values cannot be determined.
Answer:
x=67
Step-by-step explanation:
The correct statement is,
(B) f(x) has a greater maximum value than g(x).
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
Function f (x) is,
f (x) = - 8x² + 7
Now, First, we determine the maximum point of f(x).
f(x) is at maximum at the point of symmetry, i.e. where x = - b/a
Here, a = -8, b = 0
Hence, x = - 0 / - 8 = 0
So, We get;
f (0) = - 8 x 0 + 7 = 7
Thus,
The maximum point of f(x) is (0,7)
And, The maximum point of g(x) is (2,6)
Therefore, f(x) has a greater maximum value than g(x).
Hence3, The correct option is B.

Find the volume of triangular prism with the following dimensions. Round to the nearest whole number.
Triangle base= 7 ft.
triangle height= 4 ft
prism height: 8.5 ft
Answer:
124.0 ft^2
Step-by-step explanation:
let b = base of triangle = 7ft
h = height of triangle = 4ft
and
l = height of prism. = 8.5ft
We know,
volume of prism = area of triangular face of prizm × height of prizm
= 1/2 × b × h × l
= 1/2 × 7 × 4 × 8.5
= 7 × 2 × 8.5
