pantera1 [17]

Answer:

-16

Step-by-step explanation:

k = 3

-2(3) + 5 = -1

k = 4

-2(4) + 5 = -3

k = 5

-2(5) + 5 = -5

k = 6

-2(6) + 5 = -7

(-1) + (-3) + (-5) + (-7)

= -16

two nascar cars are racing around a 2 mile track. one car can complete a lap in 48 seconds, and the other car can complete one l
Citrus2011 [14]
Let's assume that the faster car has a 2 mile "head start".
The faster car is 1.2 times faster (48/40) than the slower car.
It will take five 2 mile trips to "catch" the other car.
Five 2 mile trips will take 5 * 40 seconds = 200 seconds.

The population of a town grows exponentially. After 1 year, the population is 34,560. After 2 years, the population is 37,325. W
Vladimir [108]
Exponential growth has the form:

F=Ir^t, F=final amount, I=initial amount, r=rate, t=time.

First let's solve for the rate, r, using the points provided...

37325/34560=(Ir^2)/(Ir^1)

r≈1.08  

Now find the initial amount...

34560=I(1.08)^1

I=32000 so now we have the entire equation, using x and y...

y=32000(1.08)^x

umka21 [38]

Answer:

Following are the solution to the given question.

Step-by-step explanation:

Please find the graph file and its solution in the attachment.  

4x-15=3x+28\\\\4x-3x=28+15\\\\x=43\\\\

Similarly:

3y+5=2y+50\\\\3y-2y=-5+50\\\\y=45\\\\

For point 1:\to KR=4x-15= 4\times 43-15=172-15=157

For point 2: \to BR=2y+50= 2\times 43+50=86+50=136

For point 3:\to BE=KR=157

For point 4:\to Kf=BR=130

For point 5:\to ERK=KFB=180^{\circ} -\angle B-\angle ERB = 180^{\circ}-92^{\circ}-18^{\circ}=70^{\circ}
