A boat that costs $8550 decreases in value by 12% per year. How much will the boat be worth after 3 years?

You have to take $8,550 times 0.12 (12%) to find out the number it is being decreased by.
8,550 x 0.12 = 1,026
And then, you have to subtract 1,026 from 8,550 three times for three years and your answer becomes 5,472.
$5,472

QUESTION POSTED AT 23/09/2019 - 04:25 AM

You are given the table below. x 4 8 12 16 20 f(x) 11 25 16 9 31 Use the table and n = 4 to estimate the following. Because the data is not monotone (only increasing or only decreasing), you should sketch a possible graph and draw the rectangles. 20 (integral) f(x)dx 4

Solution:

X      4      8       12       16          20

F(x)   11      25      16       9           31

A function is said to be increasing if , x_{1}> x_{2}, then f(x_{1})>f(x_{2}) {\text{and decreasing if } x_{1}> x_{2}, then f(x_{1})<f(x_{2}).

As you can see from the table given as x increases , f(x) increases as well as decreases.

So it is increasing as well as decreasing function.

Now plotting the graph on two dimensional coordinate plane and drawn perpendicular from these points on X axis.

\int_{4}^{20}f(x)dx=\int_{4}^{8}f(x)dx+\int_{8}^{12}f(x)dx+\int_{12}^{16}f(x)dx+\int_{16}^{20}f(x)dx

Equation of line joining two points (x_{1},y_{1}), and (x_{2},y_{2}) is \frac{y-y_{1}}{x-x_{1}}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Equation of line joining two points (4,11) and (8,25) is

4(y-11)=14(x-4)

4 y -44 = 14 x -56

4 y = 14 x -12

y= \frac{7x}{2}-3 --------(1)

Area under line (1) is

\int_{4}^{8}f(x)dx=\int_{4}^{8}(\frac{7x}{2}-3) dx=\frac{7x^2}{4}-3x\left \{ {{x=8} \atop {x=4}} \right. =112-24-28+12=72

Equation of line joining (8,25) and (12,16) is

4(y-25 )= -9(x-8)

4 y - 100= -9 x + 72

4 y = -9 x + 172

y = \frac{-9x}{4} +43--------(2)

Area under line 2 is

\int_{8}^{12}f(x)dx=\int_{8}^{12}(\frac{-9x}{4} +43)dx=\left \{ {{x=12} \atop {x=8}}   \frac{-9x^2}{8} +43x = -162 +516+72-344=82

Equation of line joining (12,16) and (16,9) is

-4(y-16) = 7(x-12)

-4 y + 64= 7 x -84

-4 y = 7 x -148

y = \frac{-7x}{4} +37-----------(3)

Area under the line 3 is

\int_{12}^{16}f(x)dx=\int_{12}^{16}(\frac{-7 x}{4} +37)dx=\left \{ {{x=16} \atop {x=12}}   \frac{-7x^2}{8} +37 x = -224 +592+126-444=50

Equation of line joining (16,9) and (20,31) is

4(y-9) = 22(x-16)

4 y - 36 = 22 x - 352

4 y = 22 x - 316

y= \frac{11x}{2}-79---------(4)

Area under the line 4 is

\int_{16}^{20}f(x)dx=\int_{16}^{20}(\frac{11 x}{2} -79)dx

=\left \{ {{x=20} \atop {x=16}}   \frac{11x^2}{4} -79 x = 1100-1580-704+1264=2364-2284=80


Total Area = Area under the line (1+2+3+4)

=\int_{4}^{20}f(x)dx=\int_{4}^{8}f(x)dx+\int_{8}^{12}f(x)dx+\int_{12}^{16}f(x)dx+\int_{16}^{20}f(x)dx

= 72 +82+50+80

= 284 square units

You can find area using the formual of area of trapezoid which is = \frac{1}{2}[Sum of parallel sides]× [perpendicular distance between them]

We want to figure out how much area the paint covered,

So,

9* 10 = area of the wall

adding the other 46 we can assume that the paint covered,

QUESTION POSTED AT 23/09/2019 - 04:20 AM

Gerald is conducting an experiment with 3 possible outcomes. Kasey is conducting an experiment with 20 possible outcomes. Which statement best relates the sample space to the number of trials needed to produce results similar to their predicted outcomes? Gerald will need to conduct more trials than Kasey because there are fewer possible outcomes in his experiment. Gerald will need to conduct fewer trials than Kasey because there are fewer possible outcomes in his experiment. Gerald will need to conduct more trials because he needs to make up for the difference in the number of possible outcomes. Gerald will need to conduct fewer trials because experimental and theoretical results in experiments with small numbers of possible outcomes are the same.

Explanation with reason

As, there are 3 possible outcomes when Gerald is conducting an experiment, so the probability of each possible outcome is \frac{1}{3}, and to get it equal to Experimental probability, he needs more trials,to get the better result but less than Kasey because There are 20 possible outcomes in the experiment done by Kasey, probability of each possible outcome is \frac{1}{20}, and to get the result equal to experimental probability ,he needs more trials than Gerald.

Option B : Gerald will need to conduct fewer trials than Kasey because there are fewer possible outcomes in his experiment.

is true statement, describing Gerald and Kasey.

Jose wanted to ride his bicycle for a distance of 12 miles, but it broke down after he went only 25% of his distance. How many miles did Jose travel on his bike before it broke down?

Answer: Jose traveled 3 miles on his bike before it broke down.

Step-by-step explanation:

Given : Jose wanted to ride his bicycle for a distance = 12 miles

Cycle broke down after he went only 25% of his distance i.e = \frac{25}{100}\times 12miles=3miles

Thus Jose travelled for 3 miles before his bike broke down and he still has (12-3)= 9 miles of his distance to cover.

Thus  Jose traveled 3 miles on his bike before it broke down.

One way to remember that polynomial functions and exponential functions are different is to contrast the polynomial function y=x^2 and the exponential function y=2x. tell at least three ways they are different

A polynomial function is a relation between one variable to another variable with some restrictions to limit its behavior. In simpler terms, a polynomial function is simply a subset of functions altogether. Polynomial functions are special in that they contain zero discontinuities in their behavior, have distinct  features have end behaviors that approach infinity. These functions are excellent for demonstrating real life situations, such as banking trends.
