4 0

Answer:

< 6, - 2 >

Step-by-step explanation:

AB = b - a ( a and b are position vectors ), hence

The length of an object is measured as 65.8 centimeters what is this measurement in scentific notation
julsineya [31]

Answer:

6.58 x 10^1

Step-by-step explanation:

This is because the exponent 1 means that you have to move the decimal place in 6.58 to the right once which makes the standard form 65.8. And vice versa, if you move the decimal place to the left once in 65.8, then the answer is 6.58 x 10^1.

Find a basis for the orthogonal complement of the subspace of R4 spanned by the vectors. v1 = (1, 4, -5, 3), v2 = (4, 15, 0, 5),
Arlecino [84]

Answer:

W1 =  ( -75, 20, 1 , 0 )

W2 = ( 25, -7 , 0, 1 )

Step-by-step explanation:

attached  below is the remaining part of the solution

for a homogenous system of equation ; Ax = 0

x1 + 4x2 -5x3 + 3x4 = 0

-x2 + 20x3 -7x4 = 0         note: x3 and x4 are free variables

we can take x3 = 0 and x4 = 1 , hence ; x2 = -7

∴ x1 - 28 + 3 = 0 = x1 = 25

W2 = ( x1 ,x2, x3, x4 ) = ( 25, -7 , 0, 1 )

now lets take x3 = 1  and x4 = 0   hence x2 = 20 , x1 = -75

∴ W1 =  ( x1 , x2 , x3, x4 ) = ( -75, 20, 1 , 0 )

The quote for USD/CHF is listed as 1.4481/88. How many swiss francs does it cost to buy one dollar?
pychu [463]
Based on this quote, this answer is 60.77.

The ratio given in USD to CHF is 1.4481/88.  Since we want 1 USD, we divide both parts of the ratio by 1.4481:

1.4481 ÷ 1.4481 = 1

88 ÷ 1.4481 = 60.77

im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to t
deff fn [24]

Answer:

Step-by-step explanation: How do you find the 3rd angle of a triangle?

Image result for im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to the sum of the first two angles, find the measure of each angle.

The three angles of any triangle add up to 180 degrees. Since you know two angles (35 and 40), add them together, then subtract the total from 180 to determine the degree of the third angle.
