Find 0.1 more than a number and 0.1 less than a number. Find 0.01 more than a number and 0.01 less than a number. Find 0.001 mor
viktelen [127]

Answer:

Okay so our number in this example is going to be 23 because it is my favorite.

So you start of by saying okay

23+0.1

and that would equal 23.1

and then you would think

23-0.1

and that would equal 22.9

and then you would do the same thing just move a place

so 23+0.001

and that would equal 23.001

and then you subtract it

so 23-0.001

and that would equal 22.999

hope this helped :)

A direct variation function contains the points (–9, –3) and (–12, –4). Which equation represents the function?
katen-ka-za [31]

Answer:

\displaystyle y = \frac{1}{3}x

Step-by-step explanation:

First, find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:

\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{3 - 4}{9 - 12} = \frac{1}{3}

Then plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope</em><em> </em><em>Formula</em><em> </em>since you get it done much swiftly that way. It does not matter which ordered pair you choose:

−4 = ⅓[−12] + b

−4

\displaystyle ±0 = b \\ \\ y = \frac{1}{3}x

_______________________________________________

−3 = ⅓[−9] + b

−3

\displaystyle ±0 = b \\ \\ y = \frac{1}{3}x

**You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

I am joyous to assist you anytime.

Simplify the expression.
Marizza181 [45]
\bf \textit{Cofunction Identities}&#10;\\ \quad \\&#10;sin\left(\frac{\pi}{2}-{{ \theta}}\right)=cos({{ \theta}})\qquad &#10;\boxed{cos\left(\frac{\pi}{2}-{{ \theta}}\right)=sin({{ \theta}})}&#10;\\ \quad \\ \quad \\&#10;tan\left(\frac{\pi}{2}-{{ \theta}}\right)=cot({{ \theta}})\qquad &#10;cot\left(\frac{\pi}{2}-{{ \theta}}\right)=tan({{ \theta}})&#10;\\ \quad \\ \quad \\&#10;sec\left(\frac{\pi}{2}-{{ \theta}}\right)=csc({{ \theta}})\qquad &#10;csc\left(\frac{\pi}{2}-{{ \theta}}\right)=sec({{ \theta}})

\bf \\\\&#10;-------------------------------\\\\&#10;sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta )&#10;\\\\\\&#10;\boxed{cos(\theta )=\sqrt{1-sin^2(\theta )}}

\bf \\\\&#10;-------------------------------\\\\&#10;\cfrac{cos^2\left(\frac{\pi }{2}-x  \right)}{\sqrt{1-sin^2(x)}}\implies \cfrac{\left[ cos\left(\frac{\pi }{2}-x    \right)\right]^2}{cos(x)}\implies \cfrac{[sin(x)]^2}{cos(x)}\implies \cfrac{sin(x)sin(x)}{cos(x)}&#10;\\\\\\&#10;sin(x)\cdot \cfrac{sin(x)}{cos(x)}\implies sin(x)tan(x)

Can someone help me with both questions I will mark u brilliant
allsm [11]

1. First, he will be climbing 10,000 feet from where he is right now. 10,000 / 1,000 = 10.

-3.6 x 10 = 36 degree decrease.

25 - 36 = -11

At 12,000 feet, the temperature will be -11.

2.  First, we need to do 8.80 x 7 = 61.6

61.6 / 4 = 15.4

61.6 - 15.4 = 46.2

He has $26.20 left.

Hope this helps!
