Answer:
L = 315 cm2 ; S = 399.9 cm2
Step-by-step explanation:
Lateral area;
3 × (½)(14)(15)
315 cm²
Surface area:
315 + (½)(14)(14)sin(60)
399.8704896 cm²
Answer:
(z-9-3b)/9
Step-by-step explanation:
(z-9-3b)/9
Add 4
.. 5e^(2x) = 15
Divide by 5
.. e^(2x) = 3
Take the natural log
.. 2x = ln(3)
Divide by 2
.. x = ln(3)/2 . . . . . . . . . corresponds to the 3rd selection
To find the sum of an infinite geometric series having ratios with an absolute value less than one, use the formula, S=a11−r, where a1 is the first term and r is the common ratio.
Answer:
Lets name the first set A and the second one B.
<u>The union:</u>
- A∪B = {-7,0}∪{-3,5} = {-7, -3, 0, 5}
<u>The intersection:</u>
- A∩B = {-7,0}∩{-3,5} = ∅ as no common elements
