Answer:

324

Step-by-step explanation:

All you're simply doing is adding 8 to each number up until the 41st term OR an easier way, using the arithmetic sequence formula as shown below in the red box:

an is the term you want to find, in this case: the 41st term.

a1 is the first term in the list of ordered numbers

n is the term position, in this case, the same as an

d is the difference whether if it's adding or subtracting.

Now match the numbers in the formula and solve using PEMDAS from left to right!

(Parenthesis, exponents, multiply, divide, add, subtract)

What is an equation in point-slope form of the line that passes through the point (6, −2) and has a slope of 3? A. y + 2 = 3(x −

Nostrana [21]

Answer:

answer A is correct because the formula of equation in point slope is

y-y1=m(x-x1)

where,(x1,y1)point is given that is (6,-2)

slope=m=3

Sin^2x/cos^2 + sinxcscx = sec^2x Identify it, please explain so I know how you did it, thanks

max2010maxim [7]

$\frac{sin^2x}{cos^2x} + sin x *cscx\\ tan^2x + \frac{sin x}{sin x} \\ tan^2x + 1\\ sec^2x$

$\frac{sin^2x}{cos^2x} = tan^2x$

$csc x = \frac{1}{sinx}$

$tan^2x + 1 = sec^2x$

The equation below can be used to find the length of a foot or forearm when you know one or the other. (length of the foot) = 0.

3241004551 [841]

This is child's play.

So, basically:
Y=Length of foot
X= Length of your forearm.
This is simple. Your equation is Y=0.860x + 3.302
So, if you have a forearm (x) that is 17 inches long, then plug in x as 17. This leaves you to evaluate for Y.
New equation: Y=0.860(17) +3.302
Work it out, you get: Y=14.62 + 3.302
Work that out, you get: Y= 17.922 inches long.
And of course, Y is the foot.

So, your answer: If the forearm is 17 inches long, then the foot is 17.922 inches long. Simple.

So, part 2:
Rate of change. Well, you need slope then, because that's the same thing.
Y=mx+b, Where m=slope
Your answer turns to be 0.860 inches per length of arm, for rate of change.

Skipping the data, as that's only something you'd know.

Yes, it is indeed a function. There can't be any exponents greater than 1 on the placeholder, and it's obviously not a straight line if you plug it in.

So yeah, it's a function.
