Answer:
a) <DXC and < CXB are complementary angles
b) Supplementary angles
<AXB and <DXB
<AXC and DXC
Step-by-step explanation:
Complementary angles: Two angles are complementary angles if their sum equals 90°
Supplementary angles: Two angles are Supplementary angles if their sum equals 180°
a) Name a pair of complementary angles
So, <DXC and < CXB are complementary angles
b) Name two Supplementary angles pair
<AXB and <DXB (their sum equals 180°)
<AXC and DXC ((their sum equals 180°))
Answer:
$6 more
Step-by-step explanation:
14 - 8 = 6 so she needs $6 more
5k-3+9+k=180
6k+6=180
6k=174
k= 174/6= 29
2(180-2h)+40=180
360-4h=140
4h=360-140=220
h=55
Answer: is in the picture
For this case we have the following equation:
y (t) = 35 * exp (3t) + 57
For 200 bacteria we have:
200 = 35 * exp (3t) + 57
Clearing t we have:
exp (3t) = (200-57) / 35
exp (3t) = 4.085714286
ln (exp (3t)) = ln (4.085714286)
3t = ln (4.085714286)
t = ln (4.085714286) / 3
t = 0.5 minutes
Answer:
the population will reach 200 bacteria at:
t = 0.5 minutes
or
t = ln (4.09) / 3
