Answer:

C

Step-by-step explanation:

Use the distance formula.

We have the points (0,0) and (8,sqrt17)

This basically means sqrt(8^2+sqrt(17)^2)

Which amounts to

sqrt(64+17)

Which is

sqrt(81)

Which is 9.

Find the value of the following expression (2^8 • 3^-5 • 6^0) write your answer in simplified form show all your steps Help Fast
vitfil [10]
{( {2}^{8} \times {3}^{ - 5} \times {6}^{0} })^{ - 2} \\ = \frac{1}{ {( {2}^{8} \times {3}^{ - 5} \times {6}^{0} })^{2} } \\ = \frac{1}{ {(256 \times \frac{1}{ {3}^{5} } \times 1 })^{2} } \\ = \frac{1}{ {(256 \times \frac{1}{243} \times 1 })^{2} } \\ = \frac{1}{ ({ \frac{256}{243} })^{2} } \\ = \frac{1}{ \frac{ {256}^{2} }{ {243}^{2} } } \\ = \frac{1}{ \frac{65536}{59049} } \\ = \frac{59049}{65536}
The answer is 59049/65539

Solve. −3/5x +1/5 > 7/20
Reika [66]
-3/5x + 1/5 > 7/20
-3/5x > 7/20 - 1/5
-3/5x > 7/20 - 4/20
-3/5x > 3/20
x < 3/20 * - 5/3
x < -15/60 reduces to -1/4

Explain why S = {(5, 4, -2), (-15, -12, 6), (10, 8, -4)} is NOT a basis for R^3 (1 point Sis linearly dependent and spans R3 S i
earnstyle [38]

S would be a basis for \mathbb R^3 if

(1) the vectors in S are independent, and

(2) the vectors span \mathbb R^3.

  • Linear independence requires that c_1=c_2=c_3=0 is the only solution to

c_1(5,4,-2)+c_2(-15,-12,6)+c_3(10,8,-4)=(0,0,0)

These vectors are not linearly independent because if c_1=3, c_2=1, and c_3=0, we have

3(5,4,-2)+(-15,-12,6)=(15-15,12-12,-6+6)=(0,0,0)

so S is not a basis for \mathbb R^3.
