To find out what is the next term in this pattern we need to find the pattern which we need to add or subtract and in this case it will be add. lets do it:- 

0.3, 0.5, 0.7, 0.9, ___

0.9 - 0.7 = 0.2
0.2 + 0.7 = 0.9
0.7 - 0.5 = 0.2
0.2 + 0.5 = 0.7
0.5 - 0.3 = 0.2
0.2 + 0.3 = 0.5

So to add 0.2 is the pattern. lets do it:-

0.9 + 0.2 = 1.1
1.1 + 0.2 = 1.3
1.3 + 0.2 = 1.5
1.5 + 0.2 = 1.7
and on and on

So, the pattern with the new numbers will look like, 0.3, 0.5, 0.7, 0.9, 1.1, 1.3, 1.5, 1.7.

Hope I helped ya!!

The point (1, −1) is on the terminal side of angle θ, in standard position. What are the values of sine, cosine, and tangent of
Lilit [14]

Check the picture below.

\bf (\stackrel{a}{1}~,~\stackrel{b}{-1})\qquad \impliedby \textit{let's find the hypotenuse} \\\\\\ \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies c = \sqrt{a^2+b^2} \qquad \begin{cases} c=hypotenuse\\ a=adjacent\\ b=opposite\\ \end{cases} \\\\\\ c=\sqrt{1^2+(-1)^2}\implies c=\sqrt{2} \\\\[-0.35em] ~\dotfill

\bf sin(\theta ) \implies \cfrac{\stackrel{opposite}{-1}}{\stackrel{hypotenuse}{\sqrt{2}}}\implies \cfrac{-1}{\sqrt{2}}\cdot \cfrac{\sqrt{2}}{\sqrt{2}}\implies -\cfrac{\sqrt{2}}{(\sqrt{2})^2}\implies -\cfrac{\sqrt{2}}{2}

\bf cos(\theta ) \implies \cfrac{\stackrel{adjacent}{1}}{\stackrel{hypotenuse}{\sqrt{2}}}\implies \cfrac{1}{\sqrt{2}}\cdot \cfrac{\sqrt{2}}{\sqrt{2}}\implies \cfrac{\sqrt{2}}{(\sqrt{2})^2}\implies \cfrac{\sqrt{2}}{2} \\\\\\ tan(\theta ) = \cfrac{\stackrel{opposite}{-1}}{\stackrel{adjacent}{1}}\implies tan(\theta ) = -1

When two equal forces are inclined at an angle 2a their resultant is twice as great as
swat32

Step-by-step answer:

Referring to the attached diagram, the resultant of two forces each with magnitude F and inclined to each other at 2a equals

Ra = 2Fcos(a) ..............................(1)

Similarly, the resultant of two forces each with magnitude F and inclined to each other at 2b equals

Rb = 2Fcos(b)..............................(2)

We are given that

Ra = 2Rb  ....................................(3)

Substitute (1) & (2) in (3) gives

2Fcos(a) = 2(2Fcos(b))

Expand

2Fcos(a) = 4Fcos(b)

Simplify

cos(a) = 2 cos(b)   QED

Note: Please note that you might have a faster response if you posted this question in the physics or the (new) Engineering section.

Have a nice day!

Find the coordinates of the image of the point A(3, 9) for a dilation with the scale factor of 2/3
Ierofanga [76]

Answer:

A'(2, 6 )

Step-by-step explanation:

Assuming the dilatation is centred at the origin, then multiply each of the coordinates by \frac{2}{3}

A(3, 9 ) → A'( \frac{2}{3} (3), \frac{2}{3} (9) ) → A'(2, 6 )
