Answer:
C 200
Step-by-step explanation:
It does not appear to be LINEAR so
Start with :
pulse rate = y = 73e^kx
sub in x = .7 when y = 155
155 = 73 e^(.7 * k)
ln ( 155/73) = .7k
.75296567 = .7k
k = 1.07567
for x = 0.9 :
pulse rate = y = 73 e^(1.07567 * .9) = ~ 192 so I expect answer is 200
9^5×4^3
9 has to multiply itself 5 times and 4 has to multiply itself 3 times
Y=-4x-5
-21=-4(4)+b
-21=-16+b
b=-5
y=-4x-5
