Let logp/n=5 and logm/n=9

Mathematics
1 answer:
lorasvet [3.4K]3 years ago

Answer:

we know that

log (P/N) = log P - log N

so

log P - log N = 5----------------> equation 1

log (M/N) = log M - log N  

so

log M - log N = 9 ------------------> equation 2  

If you subtract equation 2 from equation 1,

you have

log M - log P = 4  

That means that log (M/P) = 4 ----> 10^4 = M/P ---> M = 10000P

the answer is

the relationship between P and M is  

M = 10000P

18.<br> Where does the graph of y = –2x2 + 6x cross the x-axis?
algol13

Answer:

(0,0) and (3,0)

Step-by-step explanation:

When you graph y= -2x^2+6x it turns out to be a parabola. So, that means that  this parabola actually crosses two points on the x-axis; (0,0) and (3,0)

Hope this helps!

A water sprinkler has a range of 5 meters as shown. The jet of water from the sprinkler sweeps out at an angle of 85° as the noz
damaskus [11]

Take a look at the attachment below. It may help!

With this sector we can create a proportion to find the area watered by the sprinkler. 85 degrees over a total 360 degrees would be simplified to the following -

17 / 72 = ( About ) 4.235

Thus, we can calculate the area of the circle with a range of 5 meters radius, and divide by about 4.235 to receive the area watered by the sprinkler, or the area of the sector -

Area( Full Circle ) = \pi r^2,\\Area( Full Circle ) = \pi * ( 5 )^2,\\Area( Full Circle ) = 25\pi,\\\\Area( Full Circle ) = ( About ) 78.5

__________________________

Area( Watered By Sprinkler ) / Area( Sector ) = 78.5 / 4.235,\\Area( Watered By Sprinkler ) / Area( Sector ) = ( About ) 18.5

<u><em>The solution should be about 18.5 meters^2</em></u>

Express 0.9534 as a fraction
Solnce55 [7]
Express 0.9534 as a fraction

<span>0.9534 × 10 × 10 × 10 × 10 = 9534
</span><span>1 × 10 × 10 × 10 × 10 = 10000
</span>9534/10000

Divide by GCF:-

GCF = 2

9534 ÷ 2 = 4767
1000 ÷ 2 = 500
4767/500
^^^Improper fraction
Convert to mixed number:-

4767 ÷ 500 = <span>9.534

500 × 9 = 4500</span>

<span>4767 - 4500 =  267</span>

<span>9 = whole number</span>
<span>267 = </span>numerator
<span>500 = </span>denominator
<span>
9 267/500
 
0.9534 = 9537/10000 = 4767/1000 = 9 267/500 </span><span />
