Answer:

(4,-3)

Step-by-step explanation:

If you graph this point, then it will be in the 3rd quadrant.

A 180 degree rotation will put it in the 1st quadrant.

And the extra 90 degrees will put in in the 4th quadrant, so we know that in (x,y), x is positive, and y is negative. then if you theoretically rotate it, since you are rotating it 90 degrees, 3 times, you will have to switch the x and y, since 3 is an odd number. so the final answer is (4,-3).

Answer:

(4, -3)

Step-by-step explanation:

270° clockwise = (360-270) = 90° counterclockwise

When rotating 90° counterclockwise (x, y)----> (-y, x)

(-3, -4) ---> (-(-4)), -3) =(4, -3)

A business was valued at £17000 at the start of 2011. In 6 years, the value of this business was raised to £186000. This is equi

NemiM [27]

The business was valued at £17000 at the start of 2011. In 6 years, the value of this business was raised to £186000. This is equivalent to a yearly increase of 49.0%.

Given that, A=£17000, P=£186000, r=x%, t=6 years

<h3>What is compound interest?</h3>

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.

We know that, $A=P(1+\frac{r}{100} )^{n}$

Wow, $186000=17000(1+\frac{x}{100} )^{6}$

⇒ $10.94=(1+\frac{x}{100} )^{6}$

⇒ $1.4891=1+\frac{x}{100}$

⇒ $0.4891=\frac{x}{100}$

⇒x=48.91%~49.0%

Therefore, the value of x is 49.0%.

The Perimeter Of A Rectanglular Garden Is 84 Feet . The Length Of The Garden Is Twice The Width . What Is The Width Of The Garde

nalin [4]

$\bf \stackrel{\textit{perimeter of a rectangle}}{P=2L+2W\implies 2(L+W)}~~
\begin{cases}
L=length\\
W=width\\
--------\\
P=84\\
L=\stackrel{\textit{twice the width}}{2W}
\end{cases}
\\\\\\
84=2(L+W)\implies \cfrac{84}{2}=L+W\implies 42=L+W
\\\\\\
42=(2W)+W\implies 42=3W\implies \cfrac{42}{3}=W\implies 14=W$
