Which matrix is equal to T + V

Mathematics
1 answer:
UkoKoshka [18]3 years ago
6 0

Answer:

A

Step-by-step explanation:

T11 + V11 = 0.1 + 3.2 = 3.3; T12 + V12 = -10.5

This line all by itself limits you to a and b. That's because both answers A and B begin with t11 + v11= 3.3. You just add them as you see them.  t12 + v12 = - 1.9 - 8.6 = -10.5

I'll finish off the addition, but you can see that A is right already.

t21 + v21 = 2.5 + 2.8 = 5.3;  t22 + v22 = 8.2 - 1.4 = 6.8

t31 + v31 = -7.8 - 2.3 = -10.1; t32 + v32 = 1.4 + 5.1 = 6.5

That's how these matrices  are added together.

What is the difference between the mean and the median of the following distribution?
Rudik [331]
First you find the median which is 4. The mean is calculated by the sum of the distribution divided by the amount of numbers in the distribution (20). The mean comes out to be 4.35. Subtract 4.35 from 4 and your answer is .35.

The side lengths of the following right triangle 15,20 and 25, as shown below. The altitude from the right angle splits the hypo
kompoz [17]

Answer:

h = 12

x = 9

y= 16

Step-by-step explanation:

Given

The attached triangle

Required

Find h, x and y

Let the base of the triangle be 15.

So, the area is:

A = \frac{1}{2} * 15 * 20

i.e\ height = 20

A = \frac{1}{2} * 300

A = 150

Let the base of the triangle be 25.

So, the area is:

A = \frac{1}{2}  * 25 * h

i.e\ height = h

A = \frac{1}{2}  * 25h

Substitute A = 150

\frac{1}{2}*25h = 150

Solve for h

h = \frac{150 *2}{25}

h = 6 *2

h = 12

Considering the smallest triangle

Hypotenuse = 15

So:

15^2 = h^2 + x^2

15^2 = 12^2 + x^2

This gives:

15^2 - 12^2 = x^2

81 = x^2

Take square roots

9 =x

x = 9

Solving for y

x + y = 25

y= 25 - x

y= 25 - 9

y= 16

The functions f(x) and g(x) are described below:
sesenic [268]

Suppose that the <u>function</u> f(x) is the <u>parrent</u> function and the<u> graph</u> of the function g(x)=f(x)-a can be obtained from the graph of the parrent function f(x) by <u>shifting down</u> a units.

Rewrite the expression for the function g(x) in the following way:

g(x)=32x-9=32x+8-8-9=32x+8-17=f(x)-17.

This shows that the shift down is made by 17 units.

Answer: 17 units
