<u>Trigonometry</u>

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

  • a is a leg
  • b is another leg
  • c is the hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Identify</u>

Leg <em>a</em> = 7.5

Leg <em>b</em> = 10

Hypotenuse <em>c</em> = <em>c</em>

<em />

<u>Step 2: Solve for </u><em><u>c</u></em>

  1. Substitute in variables [Pythagorean Theorem]:                                              7.5² + 10² = c²
  2. Rewrite:                                                                                                             c² = 7.5² + 10²
  3. Evaluate exponents:                                                                                         c² = 56.25 + 100
  4. Add:                                                                                                                   c² = 156.25
  5. [Equality Property] Square root both sides:                                                    c = 12.5

The estimated answer to a multiplication problem is 800,000. Which of the following expressions could result in this answer? Exp
EastWind [94]

Answer:

8,146 x 121

Step-by-step explanation:

This is a problem in which you need to measure your understading of "orders of magnitude."

If the estimated answer is 800000 that means that we are looking at a multiplication in the "order of" 8*10^5

You need to look at the "orders of magnitude" of the things you're multiplying. In the first case, we have 8146*12 that would be "of the order of" 8*10^3 times 10^1. So the whole multiplication would "of the order of" 8*10^4 or near 80000

The correct answer, 8,146 x 121, is because it's "of the order of" 8*10^3 times 10^2 and the gives us the 8*10^5 we need.

yanalaym [24]

Answer:

Sn = n/2[2a + (n-1)d]

n=11

a=2

d=3

Sn= 11/2[2(2) + (11-1)3]

Sn= 11/2(34)

Sn = 11x17

=187.

(2,-4) and (6,2).<br> Find the mid point
Olin [163]

Answer:

The answer is

<h2>( 4 , - 1)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(2,-4) and (6,2)

The midpoint is

M = ( \frac{2 + 6}{ 2}  , \:  \frac{ - 4 + 2}{2} ) \\  = ( \frac{8}{2}  \: , \:  -  \frac{2}{2} )

We have the final answer as

<h3>( 4 , - 1)</h3>

Hope this helps you
