Answer:

20%

Step-by-step explanation:

  1. Set up a proportion: \frac{280}{1400} = \frac{x}{100}  
  2. Cross multiply, then divide: 280 × 100 = 28000, 28000 ÷ 1400 = 20
  3. So, 20% were satisfied with their car

5.3.24 A is a 3times3 matrix with two eigenvalues. Each eigenspace is​ one-dimensional. Is A​ diagonalizable? Why? Select the co
abruzzese [7]

Answer:

C. No. The sum of the dimensions of the eigenspaces equals nothing and the matrix has 3 columns. The sum of the dimensions of the eigenspace and the number of columns must be equal.

Step-by-step explanation:

Here the sum of dimensions of eigenspace is not equal to the number of columns, so therefore A is not diagonalizable.

write in point slope form the equation of a line through (-3, 8) and (7, 6). A. y-6=1/5(x-7), B. y-8=-1/5(x+3), C. y-8=1/5(x=3)
Anna [14]
First you have to find the slope, the slope formula is m = y2 - y1/ x2 - x1

m = y2 - y1/ x2 - x1       (-3, 8)  (7, 6)
m = 6 - 8/ 7 - (-3)
m = -2/10
m = -1/5

point-slope formula;
y - y1 = m(x - x1)            m = -1/5   (-3, 8)
y - 8 = -1/5(x - (-3)
y - 8 = -1/5(x + 3)

so the answer is, B.

hope this helps, God bless!

The horizontal distance between two towers is 70m. The angle of depression of the top of the first tower when seen from the top
lana66690 [7]
As shown in the image, we have a 30 degree angle and x, which is what we want. By doing tan30, we can find x, so tan30=x/70 and 70*tan30=x= 70*sqrt(3)/3. 120-x=height of first tower = 120-(70*sqrt(3)/3) = roughly 79.59
