first we have to find the slope Y2-Y1/ X2- X1
7-(-1)=8
5-(-4)=9 slope= 8/9
Poin slope form ------- Y-Y =M(X-X)
Y+7= 8/9 (X+5) or
Y-1= 8/9 (X-4)
Answer: B. Vertex
Step-by-step explanation: APEX
Answer: lt will take 28.09 years for the account value to reach $37800
Step-by-step explanation:
Hi, to answer this question we have to apply the compounded interest formula:
A = P (1 + r) t
Where:
A = Future value of investment (principal + interest)
P = Principal Amount
r = Annual Nominal Interest Rate (decimal form)
Replacing with the values given
37800= 9600 (1+0.05)^t
Solving for t (years)
37800/9600 = 1.05^t
3.9375 = 1.05^t
log 3.9375 = log 1.05^t
log 3.9375 = t (log 1.05)
log 3.9375/log 1.05 = t
t = 28.09 years
Answer:9810
Step-by-step explanation:
S.I. = PRT/100
9000 ×4.5 × 2/100
S.I = 810
Amount after 2 years = 9000+810
= 9810
