56 = h/9<br> k/5 - 10 = 3<br> 3t + 5 =2
uranmaximum [27]

Answer:

h = 504, k = 65, t = -1

Step-by-step explanation:

56 = h/9

h = 56 x 9

h = 504

k/5 - 10 = 3

k/5 = 3 + 10

k/5 = 13

k = 13 x 5

k = 65

3t + 5 = 2

3t = 2 - 5

3t = -3

t = -3/3

t = -1

stellarik [79]
260.

Subtract the nth number from the (n+1)st. You get 2, 4, 8, 14, ?
Do it again for that sequence. You get 2, 4, 6, ?
Maybe that sequence is 2, 4, 6, 8, 10, 12, 14, 16, 18, ...
If so, then the sequence "above" it is 2, 4, 8, 14, 22, 32, 44, 58, 74, ...
And the original sequence is 2, 4, 8, 16, 30, 52, 84, 128, 186, 260, ...

Find all the real fourth roots of 0.0001.
Viktor [21]

Answer:

-0.1 and 0.1

Step-by-step explanation:

A fourth root is a number which multiplied by itself 4 times gives 0.0001.

Since it is an even root and the result is positive, the answer must include both negative and positive values. This is true since a negative times a negative is a positive.

0.1*0.1*0.1*0.1 = 0.0001

So the real fourth roots are -0.1 and 0.1.
