In the given image, [tex]a_{23}[/tex] is 5. The correct option is the first option 5

From the question, we are to determine which entry in the given matrix represents [tex]a_{23}[/tex]

NOTE: For any entry denoted as [tex]a_{mn}[/tex], it represents the entry in the m-th row and n-th column.

Thus,  

 [tex]a_{23}[/tex] represents the entry in the 2nd row and 3rd column.

In the given image, the entry in the 2nd row and 3rd column is 5.

Hence, in the given image, [tex]a_{23}[/tex] is 5. The correct option is the first option 5

The correct answer is option D. which is the angle x will be 38 degrees.

The measure of the angle created when two chords collide inside a circle is one-half the sum of the arcs intercepted by the angle and its vertical angle.

Here we have a measure of arc AB = 58 and the measure of arc CD = 18, So what is the value of x?

The value of x will be calculated by using the angle of arc theorem.

x  =  Sum of the arcs / 2

x  = ( 58 + 18 ) / 2

x  = ( 38 degrees )

Therefore the correct answer is option D. which is the angle x will be 38 degrees.

Answer:

  (b)  $6,769

Step-by-step explanation:

The value in the account can be found by using the compound interest formula:

  A = P(1 +r/n)^(nt)

where P is the principal invested, r is the annual rate, n is the number of times per year interest is compounded, and t is the number of years.

__

Using the given values in the formula, we have ...

  P = 5600, r = 0.019, n = 4, t = 10

  A = 5600(1 +0.019/4)^(4·10) = 5600×1.00475^40 ≈ 6768.752

The amount in the account at the end of 10 years was about $6,769.

Any number multiplied by 2 is even, therefore 2(2n + 16) is even.

If 2(2n + 16) is even, then adding 1 to this makes it odd.

A function assigns the value of each element of one set to the other specific element of another set.

The time at which the ball will hit the ground is,

h(t) = −16t² + 10t + 6

0 = -16t² + 10t + 6

8t² - 8t + 3t - 3= 0

8t(t-1)+3(t-1) = 0

(8t+3)(t-1)=0

t = -0.375, 1

Hence, the ball hit the ground at 1 second, while the function in intercept form can be written as h(t) = (−8t − 3)(2t − 2).
