The complete question is
At cycle and sport customers can rent bikes, electric scooters, kayaks, canoes, or paddleboards by the hour. Ari is renting a bi ke, and meg is renting an electric scooter. Which expression represents the total cost for Ari to rent a bike for b hours and Meg to rent a scooter for s hours (Please answer ASAP) A. 9b + 10s B. 9 + 10 C. (9+b) + (10 + s) D. 9 + 10 x b + s
Solution
The price of renting a bike for one hour is $9
The price of renting a scooter for one hour is $10
Given -
Ari rents a bike for b hours and Meg rents a scooter for s hours
Total cost of renting a bike is 9 * b
Total cost of renting a scooter is 10* s
The total cost of renting both the bike and scooter is
9b + 10s
Hence, option A is correct

It is 2.4% lower than the goal It is 1.5% higher than the goal It is 1.8% higher than the goal It is 2.4% higher than the goal It is 7.1% higher than the goal
The average job satisfaction score is 1.5% higher than the goal.
To determine how the average job satisfaction score compares to the goal, we need to calculate the average job satisfaction score from the given data and compare it to the goal of 84%.
The average job satisfaction score can be calculated by taking the sum of the job satisfaction scores for each month and dividing it by the total number of months (6 in this case).
Sum of job satisfaction scores = 82 + 82 + 85 + 86 + 88 + 90 = 513
Average job satisfaction score = Sum of job satisfaction scores / Total number of months = 513 / 6 ≈ 85.5%
The average job satisfaction score is approximately 85.5%. Now we can compare it to the goal of 84%.
To calculate the difference between the average job satisfaction score and the goal:
Difference = Average job satisfaction score - Goal
Difference = 85.5% - 84% = 1.5%
Therefore, the average job satisfaction score is 1.5% higher than the goal.

Are there more phones that have between 200 and 249 songs stored on them than have between 150 and 199 songs?
If there are 1,000 phones in total and 100 of them have between 200 and 249 songs while 600 of them have between 150 and 199 songs, then there are more phones with between 150 and 199 songs.
We cannot determine whether there are more phones that have between 200 and 249 songs stored on them than have between 150 and 199 songs without additional information.
For example, if there are 1,000 phones in total and 500 of them have between 200 and 249 songs while 200 of them have between 150 and 199 songs, then there are more phones with between 200 and 249 songs. However, if there are 1,000 phones in total and 100 of them have between 200 and 249 songs while 600 of them have between 150 and 199 songs, then there are more phones with between 150 and 199 songs.

If you flip the coin 96 times,how many heads?
If this is a good coin meaning that the head has as many chances as being flipped as a tail then you can expect 48.
There are only two options per flip and thus both sides have an even chance of getting flipped. So each would have half the number of flips to be flipped.
Hope that helped!

How do you calculate the axis of symmetry?
To calculate the axis of symmetry, you must first identify the shape of the figure in question. The calculation for finding the axis of symmetry is different for each shape.
Rectangle: In a rectangle, the axis of symmetry is the midline, which runs vertically through the center of the figure. To calculate the axis of symmetry, divide the width of the rectangle in half and draw a line from the midpoint of the top side to the midpoint of the bottom side.
Parallelogram: In a parallelogram, the axis of symmetry is also the midline, which runs vertically through the center of the figure. To calculate the axis of symmetry, divide the width of the parallelogram in half and draw a line from the midpoint of the top side to the midpoint of the bottom side.
Axis of symmetry is a straight line that separates a two-dimensional figure into two mirror-image halves. The line runs vertically through the center of the figure and can be found in a variety of shapes, including rectangles, parallelograms, and parabolas.

Find the derivative of the function. Simplify and express the answer using positive exponents only.
g(x) = (2x4 + 9)^2 (x3 − 7x)^3
Finally, we can simplify by combining like terms and expressing the answer using positive exponents only: g'(x) = 32x³(2x⁴ + 9)(x⁹ − 21x⁷ + 147x⁵ − 343x³ + 343x) + (2x⁴ + 9)²(117882x² - 588x³ + 686x)².
What is derivative?In calculus, the derivative is a mathematical concept that describes how a function changes as its input (also known as the independent variable) changes. It measures the rate at which the function is changing at a specific point, which is the slope of the tangent line to the curve of the function at that point. The derivative of a function f(x) is denoted as f'(x) or df(x)/dx and represents the instantaneous rate of change of the function with respect to its input x. The derivative can be used to find the maximum and minimum values of a function, to calculate the slope of a curve, and to solve optimization problems in various fields such as physics, engineering, and economics.
Here,
We will use the chain rule and product rule to find the derivative of the function g(x) = (2x⁴ + 9)²(x³ − 7x)³:
g(x) = (2x⁴ + 9)² (x³ − 7x)³
g'(x) = 2(2x⁴ + 9)¹(8x³)(x³ − 7x)³ + (2x⁴ + 9)²(3x²-7)(3x²-7x)²
Simplifying this expression gives:
g'(x) = 16x³(2x⁴ + 9)(x³ − 7x)³ + (2x⁴ + 9)²(3x²-7)(3x²-7x)²
We can further simplify this expression by distributing the factors and combining like terms:
g'(x) = 32x³(2x⁴ + 9)(x⁹ − 21x⁷ + 147x⁵ − 343x³ + 343x) + (2x⁴ + 9)²(117882x² - 588x³ + 686x)²

Answer:
A. Y-68=-5(x-14)
Step-by-step explanation:
Mary is spending money at the average rate of $5 per day. After 14 days she has $68 left. The amount left depends on the number of days that have passed. write an equation for the situation
We find the equation using the point slope equation of a line. This is given as:
y - y1 = m(x-x1)
The slope intercept form will be
y = -5x + b
since the amount decreases by $5 per day...
Our slope is -5 so m=-5
We have a point (x1,y1) = (14, 68)
Hence, we have:
y-68 = -5(x-14)
Option A is correct
