The rate of growth in the exponential function is 1.98%

An exponential function is defined by the formula f(x) = aˣ, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.

To solve this problem, we have to model the growth in an exponential function.

Population in 1997 = 2.12 million

Population in 2006 = 2.53 million

Time = 9

Since this is an exponential growth function, we can write this as;

2.53 = 2.12(1 + r)⁹

where r = rate of growth

2.53 = 2.12(1 + r)⁹

r = 0.0198

r = 1.98%

The rate of growth is 1.98%

Answer:

Step-by-step explanation:

since you are rotating the image it shows y k j and l so it would be 5.5

Answer:

length is 4 units

width is 2 units

Perimeter is 12 units

Area is 8 sq units

Step-by-step explanation:

Since you have a graph of the points, you can see the shape is a rectangle. Count to find the measure of the length and width.

Perimeter is the distance all the way around the shape.

length + width + length + width

Or 2(length)+2(width)

= 2 + 4 + 2 + 4

= 12

Area is

length × width

= 4 × 2

= 8 sq units.

The correct application of the quotient rule is  f'(x) = [(3x - 2)2x - (x²+5)(3)]/[(3x - 2)]²

The derivative of a function f'(x) is the rate of change of the function with respect to a variable.

Since we have f(x) = (x²+5)/(3x-2), to find its derivative f'(x), we use the quotient rule.

Given a function f(x) = u(x)/v(x) then the derivative of f(x) which is f'(x) = [v(x)du(x)/dx - u(x)dv(x)/dx]/[v(x)]²

So, with f(x) = (x²+5)/(3x-2)

u(x) = (x²+5) and v(x) = (3x-2)

So, du(x)/dx = d(x²+5)/dx

= d(x²+5)/d(x²+5) × d(x²+5)/dx

= 2x

and

dv(x)/dx = d(3x - 2)/dx

= d3x/dx - d2dx

= 3 - 0

= 3

Since  f'(x) = [v(x)du(x)/dx - u(x)dv(x)/dx]/[v(x)]², substituting the values of the variables into the equation, we have that

f'(x) = [v(x)du(x)/dx - u(x)dv(x)/dx]/[v(x)]²

f'(x) = [(3x - 2)2x - (x²+5)(3)]/[(3x - 2)]²

So, the quotient rule is  f'(x) = [(3x - 2)2x - (x²+5)(3)]/[(3x - 2)]²

The time left before the fossil fuel reserves run out is 2000years(1significant figure)

A rate is a special ratio in which the two terms are in different units. For example, if a 14-ounce can of corn costs 69¢, the rate is 69¢ for 14 ounces. Rate can also be defined as the ratio of two unlike units.

The total metric tonnes of fossil fuel on earth is 2.1×10⁸.

The rate of usage is 1×10⁵ metric tone of fossil fuel per year

as been said rate = total metric tone of fuel/ number of years to use

1×10⁵= 2.1×10⁸/no of years

no of years = 2.1×10⁸/1×10⁵

no of years = 2.1×10³years= 2100years

to 1 significant figure = 2000years

therefore the number of years for the fossil fuel to run out is 2000years

a. Constant speed, C =  0. 19 miles/minutes

b. The fraction representing her constant speed is  1/x miles/minutes

c. The time it takes her to drive exactly 1 mile is 5. 38 minutes

The formula for calculating constant speed is expressed as;

Constant speed = total distance covered/ total time taken

From the information given, we have that;

Now, substitute the values into the formula

Constant speed = 1. 3 / 7

Divide the values

Constant speed = 0. 19 miles/minutes

When distance 1 mile, time taken = x minutes

Constant speed = 1/x miles/minutes

If 1. 3 miles = 7 minutes

Then, 1 mile = x

cross multiply

x = 7/1. 3

x = 5. 38 minutes

Hence, the constant speed is 0. 19 miles/minutes

Graph ii shows that 150 people preferred eating ice cream from a cone, while 60 people preferred eating ice cream from a cup. There was no association between age and preferred method of eating ice cream.

Graph ii is a table that shows the distribution of responses to the survey about preferred method of eating ice cream. The table shows that out of the 210 people surveyed, 70 were adults and 140 were children. Of the 210 people surveyed, 150 indicated the cone as the preferred method of eating ice cream, while 60 indicated the cup as the preferred method. This table indicates that there is no association between age and preferred method of eating ice cream, as the responses were evenly distributed between adults and children. This information can be used to determine the preferences of customers at the ice-cream store and can help inform decisions about how to serve the ice cream. For example, the store may choose to provide more cones than cups based on the survey results. Additionally, this table can be used to compare the preferences of different demographic groups, although in this case the survey showed that there was no association between age and preferred method of eating ice cream.

Lower estimate obtained would be = 35.4 liters

Upper estimate obtained would be = 35.4 liters

What is Estimate?

Estimation finds an estimate or approximation.

An approximation is a value, amount, or size closest to the true value found by rounding off.

To find upper and lower estimates for the total quantity of erupted materials after six seconds using six equal subintervals, we can use the left endpoints and the right endpoints of the subintervals to find the estimates.

The lower estimate is obtained by using the left endpoints of the subintervals to estimate the value of r(t) at each subinterval. Since there are six subintervals, we have:

lower estimate = (28 + 18 + 34 + 48 + 54 + 60) * (6/6) = 324 tons

The upper estimate is obtained by using the right endpoints of the subintervals to estimate the value of r(t) at each subinterval. We have:

upper estimate = (18 + 34 + 48 + 54 + 60 + 60) * (6/6) = 324 tons

To use the midpoint rule to estimate Q(6) using three equal subintervals, we need to find the midpoints of the subintervals. The subintervals are [0,2], [2,4], and [4,6]. The midpoints are 1, 3, and 5. The value of r(t) at these points is 18, 48, and 54 respectively. The midpoint rule estimate is given by:

Q(6) = (18 + 48 + 54) * (6/3) = 180 tons

To find lower and upper estimates for the total amount of oil leaked over the interval [0, 10] using five equal subintervals, we can again use the left endpoints and the right endpoints of the subintervals to find the estimates. The lower estimate is obtained by using the left endpoints of the subintervals to estimate the value of r(t) at each subinterval. The upper estimate is obtained by using the right endpoints of the subintervals to estimate the value of r(t) at each subinterval.

The subintervals are [0,2], [2,4], [4,6], [6,8], and [8,10]. The left endpoints are 0, 2, 4, 6, and 8, and the right endpoints are 2, 4, 6, 8, and 10. The lower estimate is obtained by using the left endpoints:

lower estimate = (8.6 + 7.5 + 6.7 + 6.4 + 5.7) * (10/5) = 35.4 liters

The upper estimate is obtained by using the right endpoints:

upper estimate = (7.5 + 6.7 + 6.4 + 5.7 + 5.1) * (10/5) = 35.4 liters

Hence, The Lower estimate obtained would be = 35.4 liters and

When you start from the given set of rules and conditions and determine must be true you are using c) Deductive reasoning.

In deductive reasoning, conclusions are reached based on premises that are typically taken to be true. It employs a logical premise to arrive at a logical conclusion and is also known as "deductive logic." The term "top-down reasoning" is frequently used to describe deductive reasoning. If something is presumptively true and a different object is connected to the first presumption, then the original truth must also apply to the second. Syllogism is one of the most popular forms of deductive reasoning. A major and a minor assertion coming together to make a logical conclusion is referred to as a syllogism. The fact that the two statements are true indicates that the assertion will probably be true for all further premises belonging to that category.

The average would be 50. Everyone ought to guess 33 if they are all aware of this. However, if I know that everyone correctly predicted 33, then 33 is the average, and should seek 2/3*33=22. This logic continues until everyone should correctly guess 0.

People actually don't think this way, but I disagree that you should guess between 5 and 10, which I believe is too low. depending on who you play with, as a group of game theorists might get a lower average than a group of people from the average population.) In a real-world setting, you need to consider how many iterations the others will make. You should guess 22 if you think they will only do one, which would result in everyone guessing 33.
