What is the slope of a line passing through the points (1,-10) and (4,12)

1 answer:

4 0

You would start out with the equation (y2-y1) over (x2-x1). So to solve this problem it would be (12-(-10) over (4-1) and your answer would be 22/3.

If f(x) = -(1/x^3) and x takes on successive values from -10 to 0.1 ,

prohojiy [21]

Alright, this one is a little interesting... Let's perform some tests to figure out what is happening:
f(-10) = -(1/(-10)^3) = -(1/-1000) = 1/1000 (positive)
f(-5) = -(1/(-5)^3) = -(1/-125) = 1/125 (positive, bigger than the last one)
f(-1) = -(1/(-1)^3) = -(1/-1) = 1 (positive, bigger than the last one)
f(-0.1) = -(1/(-0.1)^3) = -(1/-0.001) = 1/0.001 = 1000 (positive, bigger than the last one)
f(0) = -(1/0^3) = undefined!
f(0.1) = -(1/(0.1)^3) = -(1/0.001) = -1/0.001 = -1000 (negative)
f(1) = -(1/1^3) = -(1/1) = -1 (negative, but bigger than last one)

It's a little confusing with the undefined part at x = 0. What I can say is this, it is increasing from -10 up to 0, something weird happens at 0 and it resets, and starts increasing from 0 up to 0.1.

I guess A would be the best answer?

Rounded to three decimal places, the value of the irrational number e is .A.3.142B.3.615C.2.718D.2.947

notka56 [123]

REQUIRED:

Round to 3 decimal placed the value of the irrational number e.

Step-by-step solution/explanation;

The letter e in mathematics is also known as the Eular's number and is a mathematical constant used in many calculations especially natural logarithms of numbers.

The value of the Eular's number is approximately;

$e\approx2.71828182846...$

It can continue till infinity, however approximations of this number is always used to avoid unnecessary complications.

Therefore, rounded to 3 decimal places, the value of e is now;

ANSWER:

$e\approx2.718$

Note that we take 3 digits aftre the decimal and then if the fourth digit after the decimal is 5 or greater than 5, we make it 1 and add that 1 to the third digit after the decimal. Otherwise we simply make it zero and cancel it along with all other digits after it.

The digit that follows 8 (third digit) is less than 5, therefore, we write it off along with all other digits after it, and we are left with the decimal point and then ...718.

Option C is the correct answer.

1. Which correspondence accurately describes the two congruent triangles shown here?

saul85 [17]

Traiangle ABE = triangle CBD this is wrote right

bc. to angle A corespond angle C
and to angle B corespond angle B
and to angle E corespond angle D

so and than you check this posted image these coresponding angles are congruent angles what mean that these two triangles are congruent
