Where are your choices

Analyze the graph of the function f(x) to complete the statement. <br>

ExtremeBDS [4]

Answer:

Step-by-step explanation:

What they are asking for here is where the y-values are negative in interval format. Intervals are x things only, no y's allowed. So the interval of (-infinity, -3) indicates an x value of negative infinity to an x value of -3. The y's are negative from an x value of negative infinity to an x-value of -3, then again from an x value of almost -1 to an x value of almost positive 1. So your choice is the last one listed there.

Find the dimension of the subspace spanned by the given vectors. [Start 3 By 1 Matrix 1st Row 1st Column 1 2nd Row 1st Column ne

vladimir1956 [14]

Answer:

Step-by-step explanation:

Given the following column vectors

(1, -2, 0), (-1, 3, 1), (2, 1, 5) and (-1, 1, 1)

Before we can get the dimension of the vector, the following steps must be followed;

Step 1:

We need to transform the vectors given into a matrix form and then reduce the resulting matrix.

Step 2:

Then we generated the basis of the matrix (new set of column vectors from the reduced matrix).

Step3:

The total number of column vectors generated will be equivalent to the dimension of the vectors.

The dimension spanned by the set of vectors is 4

Can some body help me with this

Volgvan

Answer:

1 is 11

3 is 12

5 is the same answer as 3

Step-by-step explanation:

for #1 the angle is 90 degrees and its asking to find x you can set up the equation by sayin 46+4x=90 you substract 46 by 46 and subtract 90 by 46 then you will get 4x=44 dived 4 on each side and you will get x = 11

for #3 the angle is equal to 180 you set up the eqation by saying 36+12x=180 you subtract 36 by itself and 180 by 36 then you will get 144 now your equation is 12x = 144 now divide 12x by 12 and 144 by 12 and you will get x = 12

What number should be added to both sides in order to solve x^2 -8x=0

GREYUIT [131]

Answer:

Step-by-step explanation:

x^2 -8x=0

rewrite in this form and add 16 to both sides:

x² + 2(- 4)x + 16 = 0 + 16

(x - 4)² = 16 ( take square root of both sides )

x - 4 = ± 4

x = 4 ± 4

x=8 , x= 0
