Answers

Answer 1

The dimension of Nul A = 0 and the dimension of Col A = 4. means that the matrix A has no solutions for the homogeneous equation A × x = 0, which means that its null space is trivial, and it has 4 linearly independent columns, which means that its column space is 4-dimensional.

In other words, it is the number of linearly independent vectors x that satisfy the equation Ax = 0.

The dimension of Col A, also known as the column space of the matrix A, is the dimension of the subspace spanned by the columns of the matrix A. In other words, it is the number of linearly independent columns of matrix A.

In general, it is not possible to determine the dimensions of Nul A and Col A of a matrix just by looking at its elements. In order to find the dimensions, we need to perform the row echelon form or reduced row echelon form of the matrix to find the rank and the nullity which is the difference in the number of columns and rank.

For the specific matrix A provided, the rank of the matrix is not provided, thus we can not determine the dimension of the Nul A and Col A.

suppose that the population of deer in a state is 16,000 and is growing 1%each year Predict population after 6 years

Answers

Answer:

16984

Step-by-step explanation:

Given

[tex]a = 16000[/tex] ---- Initial

[tex]r = 1\%[/tex] --- rate

Required

Determine the population after 6 years

To do this, we make use of the following exponential function

[tex]f(x) = a(r+1)^x[/tex]

Substitute values for a and r

[tex]f(x) = 16000(1\%+1)^x[/tex]

Express 1% and decimal

[tex]f(x) = 16000(0.01+1)^x[/tex]

[tex]f(x) = 16000(1.01)^x[/tex]

The population after 6 years is:

Substitute 6 for years

[tex]f(6) = 16000(1.01)^6[/tex]

[tex]f(6) = 16984.3224096[/tex]

[tex]f(6) = 16984[/tex] -- approximated

On one day, 4 chefs and 5 helpers earned $650.

On another day working the same number of hours
at the same rate of pay, 5 chefs and 6 helpers
earned $800.

How much does a chef earn each
day?

Answers

4c + 5h = 650 and

5c + 6h = 800 where c are chefs, h are helpers

Start by finding an expression for c

4c + 5h = 650
4c = 650 -5h
c = (650- 5h)/4

Then substitute that into the second equation and solve for a number value for h
5 (650-5h)/4 + 6h = 800
(3250-25h)/4 + 6h = 800
Multiply both sides by 4
3250-25h + 24h = 3200
-h = -50
h = 50

Take that 50 and substitute it into the expression we have for c to get a number value for c

C= 650-5(50)/4
C = 650-250/4
C = 400/4
C= 100

Check your first equations, substituting $50 for the helpers and $100 for the chefs.

4 (100) + 5(50) =
400 + 250 = 650

5(100) + 6(50) =
500 + 300 = 800

a hotel ballroom is decorated with tulips, roses and peonies. The ratio of the number of tulips to the number of roses in the ballroom. there are 575 stalks of flowers in the ballroom altogether. how many tulips are there​

Answers

Answer:

200 tulips

Step-by-step explanation:

The computation of the number of tulips are shown below:

Given that

Ratio of number of tulips to number of ratios is 2:3 we can write 8:12

And, the peonies to roses are 1:4 we can write as 3:12

So,

Tulips : Roses : Peonies

8:12:3

Now

Total units of flowers + 8 + 12 + 3

= 23

For tulips it would be

= 575 × 8 ÷ 23 units  

= 200 tulips

We notice that there is one set where all values are very close to the average . This is the set:

Find the length of MN:

MN²=(Yn-Ym)²+(Xn=Xm)²

MN²=(4-1)²+(3-1)²

MN²=3²+2²

MN²=9+4

MP=√13

Find the measures of all the angles listed and if the lines are parallel explain why?

Answers

Answer:

x= 110°

Step-by-step explanation:

if you continue drawing the top purple line you will have a triangle with three angles

70° ; is given

180-140= 40°; is the same angle as the supplement angle of 140° (complementary angles are congruent)

180-70-40 = 70°; because sum of angles in a triangle is 180°

So angle x= 180 -70 = 110 because are a linear pair

Answer:

110 deg

Step-by-step explanation:

The supplement of the 140 deg angle measures 40 deg.

Draw a line through the vertex where angle x is that is parallel to the other two lines. That line splits angle x into two angles, an upper angle and a lower angle.

By alternate interior angles, the lower angle that is part of angle x measures 70 deg. Also by alternate interior angles, the upper angle that is part of angle x  measures 40 deg.

x = 70 + 40 = 110

Answer: 110 deg
