Answer: y=12/5 and P=120

Step-by-step explanation:

Set (10y-4)=(5y+8) which makes y=12/5

Substitute y in for both PS and QR to get 20 and 20

If PQ=2PS, then 2(20)=40. Do the same for SR to also get 40

40+40+20+20=120

oksano4ka [1.4K]

Answer:

\red{{7}^{15} }

Step-by-step explanation:

We know that,

{x}^{a}  \times  {x}^{b}  =  {x}^{a + b}  \\ ( {x}^{a} ) ^{b}  =  {x}^{ab}

Accordingly,

( {7}^{5} ) ^{3}  \\  {7}^{5 \times 3}  \\  {7}^{15}

\\ \sf\longmapsto (5+2)x+2=16

\\ \sf\longmapsto 7x+2=16

\\ \sf\longmapsto 7x=16-2

\\ \sf\longmapsto 7x=14

\\ \sf\longmapsto x=\dfrac{14}{7}

\\ \sf\longmapsto x=2

in 2012, the population of a city was 63,000. by 2017, the population was reduced to approximately 54,100. identify any equation
Akimi4 [234]

Answer:

<em></em>f(x) = 63000(0.97)^x<em></em>

<em></em>

Step-by-step explanation:

Given

f(0) = 63000 ---x = 0, in 2012

f(5) = 54100 -- x = 5, in 2017

Required

Select all possible equations

Because there is a reduction in the population, as time increases; the rate must be less than 1.

An exponential function is represented as:

f(x) = ab^x

Where

b = rate

rate > 1 in options (a) and (b) i.e. 1.03

This implies that (a) and (b) cannot be true

For option (c), we have:

f(x) = 63000(0.97)^x

Set x = 0

f(0) = 63000(0.97)^0 = 63000*1=63000\\

Set x = 5

f(5) = 63000(0.97)^5 = 63000*0.8587=54098.1 \approx 54100

<em>This is true because the calculated values of f(0) and f(5) correspond to the given values</em>

For option (d), we have:

f(x) = 52477(0.97)^x

Set x = 0

f(0) = 52477(0.97)^0 - 52477* 1 = 52477

<em>This is false because the calculated value of f(0) does not correspond to the given value</em>

For option (e), we have:

f(x) = 63000(0.97)^\frac{1}{5x}

Set x = 0

f(0) = 63000(0.97)^\frac{1}{5*0} = 63000(0.97)^\frac{1}{0} =undefined

<em>This is false because the f(x) is not undefined at x = 0</em>

For option (f), we have:

f(x) = 52477(0.97)^{5x

Set x = 0

f(0) = 52477(0.97)^{5*0} = 52477(0.97)^0 =52477*1= 52477

<em>This is false because the calculated value of f(0) does not correspond to the given value</em>

<em>From the computations above, only (c) </em>f(x) = 63000(0.97)^x<em> is true</em>

Help Meh por Favor
Alona [7]

Answer:

option: A and Option: B are correct.

Step-by-step explanation:

We are given a scatter plot we are asked to find which of the given statements hold true such that it's ranges describe the cluster in the scatter plot.

Clearly from the scatter plot we could see that:

The most of the points are between 6-12 years of experience in the scatter plot.

also the earnings are between $40,000 and $60,000 that covers most of the data.

Hence, option A. ( A.  between 6 and 12 years of experience) and Option B ( B.

between $40,000 and $60,000 ) are correct.
