Answer:

we get rectangular coordinates,

x= \frac{3}{2}

y =  \frac{-3√3}{2}

Step-by-step explanation:

We have given,

Polar coordinates ,P = (r , θ) = (3 , \frac{-pi}{3} )

We nee to find rectangular coordinates:

Since , x =rcosθ  and y =  rsinθ

i.e x = 3cos(frac{-pi}{3}[/tex]) = 3×\frac{1}{2} = \frac{3}{2}

And y = 3sin(frac{-pi}{3}[/tex]) = 3×\frac{-√3}{2} = \frac{-3√3}{2}

Hence we get rectangular coordinates,

x= \frac{3}{2}

y =  \frac{-3√3}{2}

If a swimmer swims 85.4 yards in 5 minutes, how many meters will he/ she swim in 70 seconds
DaniilM [7]

Distance swam in 5 minutes = 85.4 yards

Since, 1 min = 60 seconds and 1 yard = 0.91 meter

5 minutes = 5 \times 60 = 300 seconds

85.4 yards = 85.4 \times 0.91 = 77.7 meters

So, Distance swam in 300 seconds = 77.7 meters

Now, we will use unitary method to determine the distance swam in 70 seconds.

Distance swam in 1 second = 77.7 \div 300 = 0.26 meter

So, Distance swam in 70 seconds = 70 \times 0.26

= 18.2 meters

Therefore, the swimmer took 70 seconds to cover the distance of 18.2 meters.

The table below shows randy breuers height in inches leading into his teen years. The graph below displays a scatter plot of the
-Dominant- [34]
The least-square regression line has a slope of:

m=(nΣxy-ΣyΣx)/(nΣx²-ΣxΣx)

and a y-intercept of:

b=(Σy-mΣx)/n

In this case: n=7, Σxy=4899, Σy=391, Σx=85, Σx²=1153 so

m=(7(4899)-391*85)/(7(1153)-85*85))=1058/846

b=(391*846-85*1058)/(7*846)=34408/846

So the line of best fit is:

y=(1058x+34408)/846  and if we approximated this as your answers see to have done....

y=1.25x+40.67

Julie spends $5.46 at the store. Micah spends 5 times as much as Julie. Jeremy spends $6.69 more than Micah. How much money did
eduard

Answer:

Julie spent $5.46. Micah spent $27.30. Jeremy spent $33.99.

Step-by-step explanation:

Julie spent $5.46

Micah spent 5 times more than Julie, so multiply $5.46 by 5, which totals $27.30.

Jeremy spent $6.69 more than Micah, so add $6.69 to $27.30 to equal $33.99.
