Ben said that when you divide a positive decimal by a negative decimal, the answer will be less than 0.

1 answer:

3 0

I do believe that Ben's statement is always true because of the fact that when you divide a positive by a negative, or a negative by a positive, it will always equal a negative. For the equation 5.4/-6.8 the answer is -0.79411764705. And the equation -6.8/5.4 is equal to -1.25925925926. It will always equal to less then zero, except when you divide by zero.

mart [117]

Answer:

Part A

Each time you press F9 on your keyboard, you see an alternate life for Jacob, with his status for each age range shown as

either alive or dead. If the dead were first to appear for the age range of 75 to 76, for example, this would mean that Jacob

died between the ages of 75 and 76, or that he lived to be 75 years old.

Press F9 on your keyboard five times and see how long lacab lives in each of his alternate lives. How long did lacob live each

time?

Prove : (sec θ - tan θ )^2 = 1 - sin θ /1+sin θ

labwork [276]

$(sec x - tan x)^2 \\ \\ = sec^2x - 2 sec x tan x + tan^2 x \\ \\ =(1+tan^2 x) - 2 sec x tan x +tan^2 x \\ \\ =1 - 2 sec x tan x + 2 tan^2 x \\ \\ = 1 - 2tan x(sec x - tan x) \\ \\ =1 - \frac{2 sin x}{cos x} (\frac{1-sin x}{cos x}) \\ \\ = 1 - \frac{2 sin x (1-sin x)}{cos^2 x} \\ \\ =1 - \frac{2 sin x (1-sin x)}{1-sin^2 x} \\ \\ =1 - \frac{2 sin x (1-sin x)}{(1-sin x)(1+sin x)} \\ \\ =1-\frac{2 sin x}{1+sin x}$

How did the temperature change if :

Mkey [24]

<h3>Answer: Net Increase of 26%</h3>

===================================================

Explanation:

If it increases by 5%, then we use the multiplier 1.05

Think of it like saying 100% + 5% = 1 + 0.05 = 1.05

Similarly, an increase of 20% means we involve 1.20

Combine those multipliers to get: 1.05*1.20 = 1.26

This is a net increase of 26%

Interestingly, we get fairly close to 25% which is what many students might go for (since 5 + 20 = 25). This is a beginner's trap.

----------------

An example:

Let's say the temperature is 20 degrees Celsius (68 degrees Fahrenheit)

An increase of 5% means it moves to 1.05*20 = 21 degrees C

A 20% increase means we go to 1.20*21 = 25.2 degrees C

The shortcut would be to do a 26% increase to get 1.26*20 = 25.2 to help confirm we have the correct combined increase.

Answer:

AM = 4

Step-by-step explanation:

On each median the distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint, that is

AM = $\frac{1}{3}$ × 12 = 4
