is the given function continuous at x=1?
[tex]f(x) = 2x {}^{2} - 3x + 1[/tex]
A. No since the value of the function at x = 1 is 4
B. No since the function is undefined at x=1
C. Yes since the function is defined at x=1
D. Yes since the value of the function at x=1 is 4
Answer:
The answer is "Option C".
Step-by-step explanation:
Given:
[tex]\to f(x)=2x^2-3x+1\\\\when \ x=1\\\\\to f(1)= 2(1)^2-3(1)+1\\\\\to f(1)= 2(1)-3+1\\\\\to f(1)= 2-3+1\\\\\to f(1)=-1+1\\\\\to f(1)=0[/tex]
That's why choice C is correct.

A sample prepared for a chemical measurement is completed correctly by 21% of the lab technicians, completed with minor error by 70% and completed with a major error by 9%. Round your answers to three decimal places (e.g. 98.765).(a) If a technician is selected randomly to complete the preparation, what is the probability it is completed without error?(b) What is the probability that it is completed with either a minor or major error?
Answer:
0.210 ; 0.790
Step-by-step explanation:
Given that:
Percentage of correct completion by technician = 21%
Percentage of minor error = 70%
Major error in chemical measurement of sample = 9%
A.) probability that a randomly selected technician completes preparation without error:
This is equal to the percentage of correct completion by technicians :
P(correct completion) = 21% = 0.210
B.) probability that it is completed with either a minor or major error :
P(completion with minor error) + P(completion with major error)
= 70% + 9%
= 0.70 + 0.09
= 0.790

To find:
The graph of the given function.
Solution:
The vertex form of a parabola is
[tex]y=(x-h)^2+k[/tex] ...(i)
Where, (h,k) is vertex of the parabola.
We have,
[tex]y=(x-4)^2+1[/tex] ...(ii)
From (i) and (ii), we get

In ΔSTU, u = 84 inches, s = 13 inches and ∠T=165°. Find the length of t, to the nearest inch.
Answer:
97
Step-by-step explanation:
I used the law of cosines: [tex]t^{2} =s^{2} +u^{2} -2tu cos (t)[/tex]
Let plug the numbers in : t^2=[tex]13^{2} +84^{2} -2(13)(84)cos (165)[/tex] which approx is 97 to the nearest inch.
The length of 't' is approximately 69 inches.
How to calculate the length?To find the length of t, we can use the Law of Cosines, which states that for any triangle with sides a, b, and c and opposite angles A, B, and C, respectively:
a²= b² + c² - 2bc cos(A)
In this case, we want to find the length of t, which is opposite to the given angle ∠T. We know that:
u = 84 inches (opposite to angle ∠U)
s = 13 inches (opposite to angle ∠S)
∠T = 165°
Let's substitute these values into the Law of Cosines:
t² = u²+ s²- 2us cos(T)
t²= (84)²+ (13)² - 2(84)(13) cos(165°)
t²= 7,056 + 169 - 2(84)(13)(cos(180°-15°))
t²= 7,225 - 2(84)(13)(cos(15°))
t²= 7,225 - 2(84)(13)(0.9659)
t²= 7,225 - 2,485.68
t² = 4,739.32
t ≈ 68.86
Rounding to the nearest inch, the length of t is approximately 69 inches.

There will be 21 yards in 63 feet of the measurement.
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.
Given that one yard is equal to three feet. There are 63 feet of measurement.
The value of 63 feet in yards will be calculated as:-
1 yard = 3 feet
1 feet = 1 / 3 yards
63 feet = ( 63 / 3 ) yards
63 feet = 21 yards
Therefore, there are 21 yards in 63 feet of the measurement.

PLEASE HELP ILL GIVE BRAINLIEST AND FOLLOW using y=mx+b form
Answer:
y=3x
Step-by-step explanation:
The equation of a line can be written as 'y=mx+b', where 'm' is the slope, 'b' is a number, and 'x' and 'y' represent the 'x' and 'y' co-ordinates of any point on the line.
To find the slope m, take two points (x₁,y₁) and (x₂,y₂) and use the formula
m= (y₂-y₁)/(x₂-x₁)
Our points are (1,3) and (2,6):
(6-3)/(2-1)=3/1=3
Now that we have found the slope, we can write the equation as
y=3x+b
To find b, sub in a point:
9=3(3)+b
9=9+b
b=0
So our equation is y=3x

Write the standard form of the equation of the circle below.
Center (0,-1) passes through the point (-1,-2)
Answer:
[tex]x^2+(y+1)^2=2[/tex]
Step-by-step explanation:
We use the formula for a circle with center at (0, -1), that goes through the (x, y) point (-1, -2):
[tex](x-0)^2 + (y-(-1))^2 = R^2\\Using \,\,\,point\,\,\,(-1, -2)\\(-1-0)^2+ (-2+1)^2 = 1 + 1 = 2 = R^2[/tex]
Therefore, the equation of this circle can be written as:
[tex]x^2+(y+1)^2=2[/tex]

16. A car leaves a parking lot and travels directly north for
6 miles. It then turns and travels 8 miles east. How many
miles is the car from the parking lot?
Answer:
The car is 10 miles from parking lot.
Step-by-step explanation:
Given that:
The car travels 6 miles north and 8 miles east.
This forms the two legs of a right angled triangle.
The distance from car to parking lot will be hypotenuse.
Using Pythagorean theorem;
[tex]a^2+b^2=c^2\\(6)^2+(8)^2= c^2\\c^2 = 36 + 64 \\c^2 = 100[/tex]
Taking square root on both sides
[tex]\sqrt{c^2}=\sqrt{100}\\c=10[/tex]
Hence,
The car is 10 miles from parking lot.
