Answer:
78
Step-by-step explanation:
Step 1: Substitute -3 for x
6(2x^2 - 5)
6(2(-3)^2 - 5)
6(2(9) - 5)
6(18 - 5)
6(13)
78
Answer: 78
Answer:
?=78
Step-by-step explanation:
You plug in -3 for x. -3^2 is 9. Multiply 2*9 and subtract 5 from that. Get 13. Multiply 6 and 13 to get 78
Answer:
The depth of the lake baykal would be 5,315 feet
Step-by-step explanation:
Given,
The depth of the crater lake = 1,932 feet,
According to the question,
The lake baykal is 3,383 feet deeper than the crater lake,
Therefore, the depth of the lake baykal = depth of crater lake + 3383
= 1932 + 3383
= 5315 feet
Answer:
V =384 pi units ^3
or
V =1205.76 units ^3
Step-by-step explanation:
Volume of a cylinder is given by
V = pi r^2 h
where r is the radius and h is the height
V = pi (8)^2 *6
V = pi (64)*6
V =384 pi units ^3 (exact answer)
or is we used 3.14 for pi
V = (3.14) * 384
V =1205.76 units ^3
Answer: 1206.37
Step-by-step explanation:
Multiply the pie times the radius and height
3.14 * 8^2 * 6
