Answer:
6 cm
Step-by-step explanation:
If you use Tangent-secant product (chapter reference), AB/AC = AD/AB so 4/2 = AD/4. AD = 8, CD = AD - AC = 8 - 2 = 6 cm.
Answer:
Jake
Step-by-step explanation:
The average rate of change is distance divided by time. You want both of their rates in feet per second. 60 feet divided by 10 seconds is 6 feet per second. 25 feet divided by 5 seconds is 5 feet per second. 6>5
122.5.
A=b x h/2. A=122.5 b=7
A x b=h
122.5 x 7 =122.5
Answer : The substances half life in days is, 5.6 days.
Step-by-step explanation :
Half life : It is defined as the amount of time taken by a radioactive material to decay to half of its original value.
All radioactive decays follow first order kinetics.
The relation between the half-life and rate constant is:
where,
k = rate constant = 0.1235 per days
= half-life
Now put all the given values in the above formula, we get:
Thus, the substances half life in days is, 5.6 days.
Answer:
Parallelogram Height = 6 cm * sine (60)
Height = 6 * 0.86603
Height = 5.19618
Parallelogram Area = Height * Side TH
Parallelogram Area = 5.19618 * 8
Parallelogram Area = 41.56944 square cm
