X equals 9 add 1 and makes 91 iii
Answer:
Look at explanation.
Step-by-step explanation:
For the first four, take the first term and add the common difference to it to get the second term. Then add the common difference to the second term to get the third term, and so on until the 5th term. If the common difference is negative, you subtract it instead of adding it.
Step-by-step explanation:
The volume of a hemisphere is given by :
Taking differentiation,
So,
Put r = 21 m and dr = 0.03 cm = 0.0003 m
Hence, this is the required solution.
50. since n_1/4<1 the equation is not true. it has no solution.
48. same thing since 45 <= z the equation is not true.
The two triangles are similar. <span>When two </span>figures<span> are </span>similar<span>, the ratios of the lengths of their corresponding sides are equal. We use this fact in order to calculate the height of the bigger triangle. We do as follows:
QP / SL = MN / SL+SR
25 / SL = 35 / SL + 13
SL = 32.5
Area = height x base / 2
Area = SL x MN / 2
Area = 32.5 x 35 / 2 = 568.75
