Identify the initial amount a and the growth factor b In the exponential function f(x)=620•7.8x

2 answers:

6 0

Given:

f(x) = 620e^7.8x

The standard equation for an exponential function is f(x) = Aoe^bx

where Ao is the initial amount
b is the growth factor

so, in this case, the initial amount is 620 and the growth factor is 7.8

Answer:

y > 6x -100

Step-by-step explanation:

the slope intercept equation of the line is

y=mx+b

m is the slope = (y2-y1) / (x2-x1) so between the y-intercept (0,-100) and the given point (25, 50) we have m= -100-50/0-25 = -150/-25 = 6

y= 6x -100

now we have to figure the inequqlity part so take point (0, 0) that belongs to the solution and substitute in the equation

0 = 6*0 -100

0 = -100 for the equation to be true we have to make it 0 > -100, we also need to make it NOT greater or equal then because the line is doted not solid so the inequality is

y > 6x -100

Landon is saving up to buy a new jacket. He already has $70 and can save an additional $7 per week using money from his after sc

Alexeev081 [22]

For this case we have to:

Let "w" be the variable that represents the number of savings weeks.

We have that Landon's initial amount is $ 70.

We want to know how much money you have after 5 weeks, knowing that you save $ 7 each week, so be "y" the amount of money after "W" weeks:

$y = 70 + 7w$

After 5 weeks:

$y = 70 + 7 (5)\\y = 70 + 35\\y = 105\$

Answer $y = 70 + 7w\\y = 105$

If x+y=6 and xy =2find x³+y³(please help me fast with explanation also please) T^T

Maurinko [17]

Answer: x³+y³=180

Step-by-step explain: let's remember the formula x³+y³=(x+y)(x²-xy+y²) and also x³+y³=(x+y)³-3xy(x+y) then $\displaystyle\boldsymbol{ x^3+y^3=\underbrace{(x+y)^3}_{6}-3\underbrace{xy}_{2}\underbrace{(x+y)}_6}=\\\\6^3-3\cdot 2\cdot 6=216-36=180$

What is the solution set of -x^2-6<0 ?

natita [175]

Answer:

All real numbers

Step-by-step explanation:

Let's solve your inequality step-by-step.

−x2−6<0

Let's find the critical points of the inequality.

−x2−6=0

−x2−6+6=0+6(Add 6 to both sides)

−x2=6

−x2

−1

(Divide both sides by -1)

x2=−6

x=±√−6(Take square root)
