Answer:

7**6

Step-by-step explanation:

The expression 7^6 ; can be interpreted as 7 raised to the power of 6 ; which is (7 * 7 * 7 * 7 * 7 * 7). To execute this expression using a computer or basic mathematical operation on a computer we use the power symbol which the computer understand this the double multiplication symbol (**)

Hence, 7^6 = (7**6)

What number divided by 6 leaves a remainder of 5, divided by 5 leaves a remainder of 4, divided by 4 leaves a remainder of 3, an

maria [59]

Answer:

59

Step-by-step explanation:

If a number is divided by $n$ and leaves a remainder $(n-1)$ , then the number $(n+1)$ will be completely divisible by $n$ .

Therefore, when we say a number $x$ , when divided by 6, it leaves a remainder 5, then ( $x+1$ ) will be a multiple of 6.

When we say a number $x$ , when divided by 5, it leaves a remainder 4, then ( $x+1$ ) will be a multiple of 5.

When we say a number $x$ , when divided by 4, it leaves a remainder 3, then ( $x+1$ ) will be a multiple of 4.

When we say a number $x$ , when divided by 3, it leaves a remainder 2, then ( $x+1$ ) will be a multiple of 3.

So, $x+1$ is a common multiple of 3, 4, 5 and 6.

Taking LCM of 3, 4, 5 and 6, we get 60.

So, the number 60 - 1 = 59 is the least such number.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by th

Blababa [14]

Answer:

Step-by-step explanation:

so when the height is zero, that's when the rocket hits the ground. The equation will have two zeros, but one would be for a negative time, or before the rocket is launched. so we only one the one after the rocket is launched.

use the quadratic formula to solve for x ( which is time)

-124 +- sqrt [ $124^{2}$ - 4*(-16)*(127) ] / 2 (-16)

-124 +- sqrt [15376 + 8128 ] / -32

-124 +- sqrt [23504 ] / -32

-124 +- 153.310 / -32

if we take the positive part it will become the negative time so skip that one try the negative part 1st

-124 - 153.310 / -32

-277.310 / -32

8.6659 seconds to hit the ground. ( time of flight) aka TOF

8.67 seconds ( rounded to nearest 100th)
