The answer is going to be D -6

r=1/2

Sn=a(1-r^n)/1-r

S(infinite sign) = a/1-r

S(infinite sign) = -3/1-1/2

S(infinite sign) = -3/1/2

S(infinite sign) = -3/1/1*2/2-1/2

S(infinite sign) = -3/1*2/2-1/2

S(infinite sign) = -3(3*2)

S(infinite sign) = -1*6

S(infinite sign) = -6

Kristen needs to earn $320 in commission this week. She earns 8%
muminat
She needs to sell $4,000 worth of merchandise.

If she needs to earn $320, and she earns 8% commission, you’re looking for what 8% of original amount equals $320.

X = original amount
8% = .08
$320 = amount needed

X * .08 = $320.
X = $320/.08
X= $4,000

Kristen needs to sell $4,000 worth of merchandise at an 8% commission rate to earn $320.

What is the value of a for the exponential function in the graph represented in the form of f(x)=a(b^x)
Rina8888 [55]

<em><u>Note: The complete question, along with the graph, is attached below.</u></em>

<em><u /></em>

Answer:

The value of a = 3

Step-by-step explanation:

Given the function

f\left(x\right)=a\left(b^x\right)

From the attached graph, it is clear that

at x = 0,

f\left(0\right)=a\left(b^0\right)

\:f\left(0\right)\:=\:a\:\times \:1         ∵ b^0=1

f\left(0\right)=a

Thus

When x = 0, the y-intercept will be:

f\left(0\right)=a

From the attached figure, it is clear that

at x = 0, the value of y = 3

so

putting y = 3 in the equation

f\left(0\right)=a

3 = a            ∵ f\left(0\right)=y=3

Therefore, the value of a = 3
