Answer:

the scale factor is 3

Step-by-step explanation:

The scale factor is 3

The width of A is 1, the width of B is 3

the length of A is 3, the length of B is 9 so the scale factor from A to B is 3 so yeah the scale factor is 3 theres the answer

galben [10]

Answer:

t \leq 18.67\ years

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=?\ years\\ P=\$4,500\\ A=\$7,020\\r=0.03

The inequality that represented this situation is

P(1+rt) \leq A

substitute the values and solve for t

4,500(1+0.03t) \leq 7,020

(0.03t) \leq (7,020/4,500)-1

t \leq [(7,020/4,500)-1]/0.03

t \leq 18.67\ years

At a high school, 18% of the students play football and 6% of the students play football and baseball. What is the probability t
hjlf
We are given the fact that he plays football, so the probability of his being a football player is 100%.
We know that 1/3 of the football players also play baseball, so the probability that he is also a baseball player is 1/3.

Calculate the correlation coefficient for the given data below:
Rasek [7]

The correlation coefficient of the data provided is -0.52.

<h3>What is the correlation coefficient?</h3>

Correlation is a measure that is used in statistics to determine the linear relationship that exists between two variables. Correlation can be positive, negative or zero.

Positive correlation is when two variables move in the same direction. Negative correlation is when two variables move in opposite directions. Zero correlation is when there is no relationship between the variables.

Correlation can be determined using a financial calculator. When the financial calculator is used, the correlation coefficient is -0.52

Find a particular solution to the nonhomogeneous differential equation y'' + 4 y = cos(2x) + sin(2x).
alukav5142 [94]
The characteristic solution follows from solving the characteristic equation,

r^2+4=0\implies r=\pm2i

so that

y_c=C_1\cos2x+C_2\sin2x

A guess for the particular solution may be a\cos2x+b\sin2x, but this is already contained within the characteristic solution. We require a set of linearly independent solutions, so we can look to

y_p=ax\cos2x+bx\sin2x

which has second derivative

{y_p}''=(-4ax+4b)\cos2x+(-4bx-4a)\sin2x

Substituting into the ODE, you have

y''+4y=\cos2x+\sin2x
\implies4b\cos2x-4a\sin2x=\cos2x+\sin2x
\implies\begin{cases}4b=1\\-4a=1\end{cases}\implies a=-\dfrac14,b=\dfrac14

Therefore the particular solution is

y_p=-\dfrac14x\cos2x+\dfrac14x\sin2x

Note that you could have made a more precise guess of

y_p=(a_1x+a_0)\cos2x+(b_1x+b_0)\sin2x

but, of course, any solution of the form a_0\cos2x+b_0\sin2x is already accounted for within y_c.

There are eight furlongs in a mile and two weeks in a fortnight. If I travel 2800 furlongs in a fortnight, how many miles per da
katrin2010 [14]
Hello there! So, a fortnight is two weeks and two weeks is 14 days. You traveled 2,800 furlongs in two weeks. First off, let's divide the number of furlongs by the amount per mile. 2,800/8 is 350. That's 350 miles in two weeks. Now, we can divide 350 by 14 to find the amount traveled in 14 days. 350/14 is 25. There. You traveled 25 miles per day.
