Gnom [1K]

Answer:

Step-by-step explanation:

-59 - 2 + 29 - 8 = -61 + 29 - 8

Here -59 & -2 have same sign, so add both

= -61 - 8 + 29

= - 69 + 29

-69 & 29 have different sign. so subtract and the answer will have the sign of the bigger number

= - 40

Suppose a city with population 100,000 has been growing at a rate of 8% per year. If this rate continues, find the population

Natalija [7]

Answer:

$370,002\ people$

Step-by-step explanation:

In this problem we have a exponential equation of the form

$y=a(b^x)$

where

y is the population of the city

x is the number of years

a is the initial value or y-intercept

b is the base

r is the rate of growth

b=(1+r)

we have

$a=100,000\ people\\r=8\%=8/100=0.08\\b=1+0.08=1.08$

substitute

$y=100,000(1.08^x)$

For x=17 years

substitute the value of x in the exponential equation and solve for y

$y=100,000(1.08^17)$

$y=370,002\ people$

I need help ........... here’s a picture of the question

cricket20 [7]

Answer:

The answer is B. m∠ POS + m∠ POR = 180

step-by-step explanation:

Because if you already know that m∠POQ equals 90 because it is a right angle

Then all you have to do is take 90 from 180 which is 90 then divide 90 by two which is 45

now you have the measurement for the two acute angles 45

which makes m∠POS = 45 and m∠QOR =45

NOW YOU HAVE TO ADD 90 AND 45 AND 45 ALL TOGETHER THEN YOU WILL HAVE 180
