Given:

Speed of Juan = 16 mph

Time traveled = 7 hours

To find:

Total distance traveled

Steps:

Total distance traveled is equal to speed into time traveled,

Total distance = Speed × time traveled

Total distance = 16 × 7

Total distance = 112 miles

Therefore Juan traveled 112 miles in 7 hours at the speed of 16 mph

Happy to help :)

Answer:

112 Miles

Step-by-step explanation:

16 (per hour) for 7 hours

16x7 (we Multiple the speed [since its per hour] the number of hours.)

112

A denotes an mn matrix. Determine whether the statement is true or false. Justify your answer. The row space of AT is the same a

ziro4ka [17]

Answer: true

Step-by-step explanation:

For an m*n matrix, the column space of A will be a space formed by the lineal combination of all the columns of A.

column space = a1*c1 + a2*c2 + ...

where a1, a2, ... are scalars, and c1 is the vector of column 1.

Then we should write:

Column space = a1*(A₁₁, A₂₁, A₃₁, ...) + a2*(A₁₂, A₂₂, A₃₂, ...) + ...

Now, the transpose is defined as:

[At]₁₃ = A₃₁

Here i used the element with subindex 3 and 1, but is the same for every subindex.

Notice that if A is m*n, then [At] is n*m

Now, the row space of [At] will be, same as before.

Row space = b1*r1 + b2*r2 + ...

Where b1, b2, ... are scalars and the r's are the vector of each row.

= b1*( [At]₁₁ , [At]₁₂, [At]₁₃, ...) + b2*([At]₂₁, [At]₂₂, [At]₂₃, ...) + ...

Now we replace each term of the transpose by the associated element in the original matrix.

= b1*( A₁₁, A₂₁, A₃₁, ...) + b2*(A₂₁, A₂₂, ...) + ....

If we take:

b1 = a1, b2 = a2, b3 = a3, ...

We will have that the row space of [At] is the same as the column space of A.

Someone answer quick please for brainliest !

Rina8888 [55]

Answer:

The equation of the line is

$y = - \frac{1}{2} x + \frac{5}{2}$

Step-by-step explanation:

Equation of a line is

$y = mx + c$

Where m is the slope

c is the y intercept

y = 2x + 3

Comparing with the above formula

m is 2

Since the lines are perpendicular the slope of the other line is the negative inverse of the original line .

That's

m = - 1/2

Equation of the line using point (1,2) and slope - 1/2 is

y - 2 = -1/2(x - 1)

y - 2 = -1/2x + 1/2

y = -1/2x + 1/2 + 2

The final answer is

$y = - \frac{1}{2} x + \frac{5}{2}$

Hope this helps you.

What is the volume of the sphere?

Eddi Din [679]

V = 4/3 * pi * r^3
V= 4/3 3.14 * 3^3
V = 4/3 *3.14 * 27
27 * 3.14 = 84.78
V = 4/3 * 84.78 = 113.04
V = 113.04
