Answer is $330.63 because 15% of 287.5 is 43.125 then you add 47.125 to 287.5 and get 330.63

For each sequence,find the first 4 terms and the 10th term<br> a) n+5<br> b)2n-1

dsp73

Answer:

a)6,7,8,9 and 10th term is 15.

b)1,3,5,7 and 10th term is 19.

Step-by-step explanation:

Given a) n+5

b)2n-1

Solution for a) n+5

Taking the value of n is 1 we get the first term of the sequence;

$n+5=1+5=6$

Similarly taking the value of n 2,3,4 we get;

$2+5=7\\3+5=8\\4+5=9$

And for 10th term we take the value of n is 10 and get;

$n+5=10+5=15$

So the solution for 1st sequence is 6,7,8,9 and 10th term is 15.

Solution for b)2n-1

Taking the value of n is 1 we get the first term of the sequence;

$2n-1=2\times1-1=2-1=1$

Similarly taking the value of n 2,3,4 we get;

$2n-1=2\times2-1=4-1=3\\2\times3-1=6-1=5\\2\times4-1=8-1=7$

And for 10th term we take the value of n is 10 and get;

$2n-1=2\times10-1=20-1=19$

So the solution for 2nd sequence is 1,3,5,7 and 10th term is 19.

Hey there! :D

Your answer could be to multiply the quotient by the dividend.

Give the slope of each line and then determine whether the two lines are parallel,perpendicular,or neither Parallel nor perpendi

MAVERICK [17]

First, put the equations into slope-intercept form(y = mx + b):
$4x+5y=15\\5y=-4x+15\\y=\frac{-4}{5}x+3\\\\ 12x+15y=0 \\15y=-12x\\ y= \frac{-12}{15}x=\frac{-4}{5}x\\
y=\frac{-4}{5}x$
Since slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept, the slope of the line(value of m) determines whether the lines are parallel or perpendicular.
Parallel lines have the same slope, and since $\frac{-4}{5}=\frac{-4}{5}$ , the lines are parallel. Also, because the m's aren't the same, the lines aren't identical.

Your answer is parallel.

Given: sin = 4/5 and cos x = -5/13 ; evaluate the following expression. Cos 2x

Nitella [24]

For every possible angle $x$ , the fundamental law of trigonometric states that

$\sin^2(x)+\cos^2(x) = 1$

In your case, the inputs you provided would lead to

$\dfrac{16}{25}+\dfrac{25}{169} = \dfrac{3329}{4225} \approx 0.8 \neq 1$

So, it is not possible that, for a certain angle x, we have

$\sin(x) = \dfrac{4}{5},\quad \cos(x) = -\dfrac{5}{13}$
