Which formula represents calculating the slope?

k0ka [10]

C. All of the above. Both formulas represents in calculating the slope.

Step-by-step explanation:

The slope(m) can be identified by the formula rise over run.

i.e. $m=\frac{rise}{run}$ .

Rise is how much the line gone vertically ( y-axis) from the origin.

Run is how much the line gone horizontally (x-axis) from its origin.

∴ Rise = $y_{2} - y_{1}$

And Run = $x_{2} - x_{1}$ .

⇒ $m=\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ .

Thus both equations can be used to find the slope of the line intercept.

If the points are given you can chose them yourself from the graph. Just consider any two points on the line.

Does this sum converge: show steps

ehidna [41]

Answer:

Yes

Step-by-step explanation:

$\sum_{n=1}^{\infty} e^{-\sqrt{n} } \\\sum_{n=1}^{\infty} (\frac{1}{e})^{\sqrt{n} }$

If we say u = √n, then:

$\sum_{u=1}^{\infty} (\frac{1}{e})^{u}$

This is a geometric series. Since |1/e| < 1, the series converges.

Abby borrowed $3,000 at 12 3/4% on Sept. 10. The loan is to be due on Jan. 29. Assuring the loan is based on ordinary interest,

Your approach is the ideal approach...
the bone of contention here is the value of T... 

it simply depends on the definition given... some people use 360, others use 365... so it depends on which style your class (or book) uses...

Which of the following is not an integer?

In-s [12.5K]

Answer:

$-\frac{54}{7}$

Step-by-step explanation:

The first number is $\sqrt{\frac{64}{4} }$

We simplify to get: $\sqrt{\frac{64}{4} }=\sqrt{16}=4$

The second number is $-\frac{54}{7}$ .

This number can be rewritten as $7 \frac{5}{7}=7.714285714287$

This is not an integer

The third number is $(\frac{-25}{5})^2$

We simplify to get: $(\frac{-25}{5})^2=(-5)^2=25$

This is also an integer.

The correct answer is $-\frac{54}{7}$ .
