Find the largest open interval where the function is increasing. correct answer will get brainliest
Answers
Answer:
Correct answer: C. (1,∞)
Step-by-step explanation:
First Derivative
Given a real continuous function f(x), the first derivative f'(x) represents the slope of the tangent line for any value of x.
If the slope of the line is positive, then the function is increasing, if the slope of the line is negative, the function is decreasing.
The function to analyze is:
[tex]f(x)=x^2-2x+1[/tex]
Computing the first derivative:
[tex]f'(x)=2x-2[/tex]
The function will be increasing when:
[tex]2x-2>0[/tex]
Dividing by 2:
[tex]x-1>0[/tex]
Solving:
x > 1
This solution is represented by the interval (1,∞)
Correct answer: C. (1,∞)

15pts. Please Answer, Im Checking If I Am Correct Is It 8.40? A box of 100 sanitizing wipes costs $12 . How much does one wipe cost?

Answer:
$0.12
Step-by-step explanation:

what 198/28 as a mixed number?
Answers
Answer:
7 1/14
Step-by-step explanation:
198÷28 = 7.blablabla
Therefore, 7 is the integer
so you take 7 and multiply it by 28 = 196
198 - 196 = 2
Therefore, 2 is the remainder
The format for mixed numbers is Integer (remainder/denominator)
so the mixed fraction is 7 2/28
2/28 can be reduced to 1/14
Therefore the final answer is 7 1/14

What's the length of side AB in ∆ABC shown?
A. 5
B. √313
C. 6
D. √15
Answers
Answer:
The value of x = 5 units.
Step-by-step explanation:
Given the right-angled triangle ∆ABC with the following dimensions
AC = a = 12
BC = c = hypotenuse = 13
AB = b = x
Pythagorean Theorem
For a right-angled triangle with the sides, a and b the hypotenuse c is defined as:
[tex]c=\sqrt{a^2+b^2}[/tex]
Thus, using the Pythagorean Theorem to determine the value 'x',
[tex]b=\sqrt{c^2-a^2}[/tex]
as b = x, so
[tex]x=\sqrt{c^2-a^2}[/tex]
a = 12c = 13so
[tex]x=\sqrt{13^2-12^2}[/tex]
[tex]x=5[/tex]
Therefore, the value of x = 5 units.

Step-by-step explanation:
First, you would want to find the value of the original equation:
5(y + 2) + 4
Use order of operations and distribute the five.
5y + 10 + 4
5y +14
This is the value of the original equation
Now we can work through the other options, but because we already know the answer, lets see about that one.
5 x y + 5 x 2 + 4
Again, use order of operations.
Multiply first
5y + 10 + 4
and complete the equation
5y + 14, which equals our original equation.

7y=5y+36 and 3x-21=2x+4
Solve for y and then x
7y=5y+36
Subtract 5y on both sides to get
2y=36
Then divide by 2 on both sides to Get y=18
For 3x-21=2x+4,
Subtract 2x on both sides to obtain
x-21=4
Then add 21 to both sides to get

Step-by-step explanation:
simplify --- 2 5/8 = 21/8
flip 1/2 = 2/1
multiply 21/8 x 1/2
answer = 5 1/4
21/8 divided by 1/2 is 21/8×2/1 which is equal to [tex]5\frac{1}{3}[/tex].
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, are two fractions [tex]2\frac{5}{8} and \frac{1}{2}[/tex] which is,
21/8 divided by 1/2.
Now we can flip the divisor and make it a multiplier.
∴ (21/8×2/1).
= 42/8.
= [tex]5\frac{1}{3}[/tex].
