Option: A is the correct answer.

         The number of weeds is decreasing by a multiplicative rate.

Step-by-step explanation:

Clear;y from the scatter plot we could observe that with the increasing value of one variable the other variable is decreasing.

Hence, The number of weeds is decreasing.

Also as we could see that the line of best fit is a curve and not a line Hence, the number of weeds are not decreasing by a additive rate  ( since the rate or a slope of a line is constant) it is decreasing by a multiplicative rate.

<span>Given
∠FHJ = 60°
</span><span>∠FGH =  28°

</span>∠FHG = 180 - ∠FHJ
∠FHG = 180 - 60
∠FHG = 120


∠HFG = 180 - (28 + 120)

Uta invests an amount into a compound interest investment account that pays 6% a year. After six years, she withdraws her total
AnnZ [28]

Answer: $352.48

Step-by-step explanation:

Hi, to answer this question we have to apply the formula:

A = P (1 + r)^t

Where  

A: total balance after invest

P: principal amount invested

r = interest rate (in decimal form)

t = time (years)

Replacing with the values given:

500= P (1+0.06)^6

Solving for P:

500 = P (1.06)^6

500 / ( (1.06)^6)=P

500 / 1.4185 =P

$352.48= P
