Step-by-step explanation:
Please see the attached picture for the full solution.
<u>Pythagoras' Theorem</u>
• for right- angled triangles
• (hypotenuse)²= (side 1)² +(side 2)²
B. Obviously all the numbers have to do with one and it’s 30. If it’s wrong let me know !
Since t is the time after it dropped and h0 is the initial height, just substitute the things already given to you in the question
h = 1,200 - 16(2)²
h = 1,136
Therefore, the height of it then would be 1,136 feet above the ground
The statements A, B, D, and E are defined.
When we multiply matrices, the number of columns of the 1st matrix must equal the number of rows of the 2nd matrix.
<h3>What is the subtraction of the matrix?</h3>
When we add or subtract matrices, the number of rows and columns must be the same.
A) If C is 7x3 and A is 3x2, that means C has 3 columns and A has 3 rows. So C * A is defined.
B) When you transpose a matrix, the number of rows and columns are switched. So C^T has 3 rows and 7 columns. So C^T is defined.
C) B has 2 columns and C has 7 rows, so B * C is not defined.
D) Because A and B have the same number of rows and columns, we can add them. So A + B is defined.
E) B^T has 2 rows and 3 columns, and C^T has 3 rows and 7 columns. So B^T has the same number of columns as the number of rows as C^T. So B^T * C^T is defined.
F) C and A have different numbers of rows and columns, so C-A is not defined.

28.9
Step-by-step explanation:
Multiply the denominator by the number on the other side. This will give you 28.9 as t. To check your work, divide 28.9/8.5. This will give you 3.4.
