Let
y ----> total charge in a month
x ----> number of minutes
so
Plan A
y=0.21x+11
Plan B
y=0.10x+20
Equate both equations
0.21x+11=0.10x+20
solve for x
0.21x-0.10x=20-11
0.11x=9
x=9/0.11
x=81.82 minutes

Given y=x^2-2x-9 in standard form is y=(x+a)+b in vertexform, use completing the square to find a and b.
y = (x - 1)² - 10 is the vertex form of the equation y = x² - 2x - 9.
Given, y = x² - 2x - 9
The equation is already in standard form : y = ax² + bx + c
where a=1, b=-2 and c=-9 according to the equation y = x² - 2x - 9.
The vertex form of parabola is: y = a (x - h)² + k
The "a" in y = ax² + bx + c equation and the "a" in equation y = a (x - h)² + k are the same attributes of a parabola, therefore, substitute 1 for "a" in equation y = a (x - h)² + k: y = (x - h)² + k.
"h" is the x coordinate of the axis of the vertex: h = [tex]\frac{-b}{2a}[/tex]
Substitute in the values: h = - ( -2 ) ÷ 2(1)
∴ h = 1
Then, Substitute the value of h into the y = (x - h)² + k.
y = (x - 1)² + k.
Using the coordinates x and y from the above equations,
k = 1² - 2(1) - 9
k = 10
Now, Substitute the value of k into the equation y = (x - 1)² + k.
y = (x - 1)² - 10.

The height h in feet that a pole vaulter can reach can be estimated using
the formula h = 20, where v is the velocity of the athlete in feet per second.
If the height for a women's pole vault is about 9.8 feet, about how fast was
the holder running? How far will the pole vaulter run in 2 seconds?
Using the numeric value of functions, it is found that the pole vaulter will run 50 feet farther in 2 seconds.
How to find the numeric value of a function/expression?To find the numeric value of a function, we replace each instance of the variable by the desired value.
The formula for the velocity is given as;
v=8√h
where h is the height.
we have the height is of h = 9.8,
hence:
v = 8√(9.8) = 25 feet per second.
The holder was running at the rate of 25 feet per second.
Then, within two seconds, the distance is given as;
d = 25 x 2 = 50 feet.
Hence, The pole vaulter will run 50 feet farther in 2 seconds.

Step-by-step explanation:
I just put in the calculator.
for the following exercises, find the lengths of the missing sides if side a is opposite angle a, side b is opposite angle b, and side c is the hypotenuse.
Using relations in a right triangle and the Pythagorean Theorem, it is found that the missing side lengths are as follows:
a = 14.4.c = 15.24.What are the relations in a right triangle?There are three relations in a right triangle, given as follows:
The sine of an angle of the triangle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle of the triangle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle of the triangle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.For this problem, we have that:
tan(A) = b/a.
Hence:
5/12 = 6/a
Applying cross multiplication, the side a is found as follows:
5a = 72
a = 72/5
a = 14.4.
What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, stating that the hypotenuse squared is the sum of the legs squared, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
Hence the hypotenuse c is given as follows:
c² = 5² + 14.4²
c = sqrt(5² + 14.4²)
c = 15.24.

a) f is strictly increasing function then f is one to one
b) f: R-> R such that f(x) = x^n where n is even is not one to one
suppose that f is strictly increasing function
we have to prove that f is one to one
let us assume f(x1) = f(x2)
we have to prove x1=x2
since f is strictly increasing function
then x2>x1 and x1> x2
this implies that x1=x2
and Hence f is one to one function
b) f:R->R such that f(x) = x^ n where n is even is not one to one
because f(1)= f( -1)
but -1 is not equal to 1 therefore f is not one to one function

At what speed should you enter an expressway? Question 1 options: 70mph 35mph the prevailing 10 miles below the freeway traffic
At a speed of 10 mph below the freeway traffic one should enter the expressway.
The speed of an object, also known as v in kinematics, is a scalar quantity that depends on the magnitude of the change in that object's position over time or the magnitude of the change in that object's position per unit of time.
The instantaneous speed serves as the upper bound of the average speed as the duration of the time period gets closer to 0. The average speed of an object over a given period is calculated by dividing its total distance traveled over that time by its duration. Velocity and speed are not the same thing.Now of the given options since the respective speeds on various expressways are different it is tangible than to enter an expressway one must use less speed than the speed of the traffic on the expressway.

Answer step by step and give brief explanation for 20 points will also mark as brainliest
We need to know about fraction to solve this problem. The amount Reshma spent on comic books is Rs 165 and the amount that is left with her is Rs 495.
We can solve this problem by calculating what 1/4th of 660 will be. In this question we know that Reshma spends 1/4th of her pocket money on comic books out of Rs 660. We can think of 660 being divided in 4 parts equally and that Reshma spends one part of it. The amount that will be left with Reshma is the rest three parts.
Reshma spends= 1/4x660=165
Amount left= 660-165=495
Therefore the amount Reshma spends on comic books is Rs 165 and the amount that is left with her is Rs 495.

A graph of the linear equation (3x + 2y = 6) in standard form is shown in the image attached below.
What is a graph?A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
In Mathematics, the graph of any proportional relationship such as a linear equation is characterized by a straight line as shown in the image attached below.
Next, we would rewrite the linear equation in standard form as follows:
3x + 2y = 6
2y = 3x + 6
Dividing all through by 2, we have:
2y/2 = 3x/2 + 6/2
