Im really stuck on this one

Brums [2.3K]

Answer:

See below

Step-by-step explanation:

The first one IS decay...as 'x' increases the function decreases

the second and third are NOT ...as 'x' increases the value increases

radioactive decay IS decay (obviously)

the one with e^2x is not ....it grows exponentially as x grows

and finally the last one is decay because as x gets larger the value of y gets smaller

Answer:

Every day, 43% percent of people are added from the total number of people who receive the email

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

$P(t)=a(1+r)^t$

where

P(t) is the total number of people who receive the email

t is the time in days

a is the initial value

r is the rate of change

we have

$P(t)=6(1.43)^t$

$a=6$ ---> initial number of people who receive the email

$(1+r)=1.43$

solve for r

$r=1.43-1\\r=0.43$

Convert to percentage

$0.43(100)=43\%$

The daily percent change in the number of people who receive the email. every day is 43%

therefore

Every day, 43% percent of people are added from the total number of people who receive the email

An item is regularly priced at $40. It is on sale for 30% off the regular price. What is the sale price?

morpeh [17]

40$ - 100% (full price)

x$ - 70% (100-30=70%)

40 * 70 = 100x

2800 = 100x

x = 28

Answer 28$

40$ = 100%

then 1% = 40/100 = 0.4$

so 70% will be 0.4 * 70 = 28$

Sarah said that 0.00001 is bigger than 0.001 because the first number has more digits to the right of the decimal point. Is Sara

stepan [7]

Sarah would be incorrect, because the more numbers after the decimal, the smaller the number would be, because it is further away from the number one.

Which systems of equations has a solution of approximately -2,7 , -1,2

Yakvenalex [24]

The point of intersection you are concerned with is the left-most of those of the graphed lines. Thus you want the two equatons that both have x-intercepts that are negative. Since the x-coefficient is positive in every case, this will mean the right-side constants of these equations both need to be negative. The appropriate choice is ...
A. 4x - 5y = -5 and 3x + 10y = -20
