Answer:
1) The value of is 12.
2) The length of the diagonal is 49.
Step-by-step explanation:
1) If the glass is a rectangle, then both diagonal must have the same length, that is, the following equation must be solved:
(1)
We need some algebraic handling to determine the value of :
The value of is 12.
2) If we know that , then the length of the diagonal (
) is:
The length of the diagonal is 49.
Answer:
36°
Step-by-step explanation:
The computation of the measure of the angle is shown below:
As we know that
The trigonometric function in the right angle is
sinα = OS ÷ H
And,
cosα = AS ÷ H
Here
α represent the one of the angles
OS and AS represent the opposite sides
And, H represent the hypotenuse
So
sinx = 8.5 ÷ 14.5
x = arcsin = 8.5 ÷ 14.5
= 35.88
= 36 degrees
-x + y > 5 <em>add x to bot sides</em>
y > x + 5 → y = x + 5
for x = 0 → y = 0 + 5 = 5 → (0, 5)
for x = -5 → y = -5 + 5 = 0 → (-5, 0)
The dotted line (sign >, not ≥).
We shade above the line (y > ...).
Answer:
The matrix is not invertible.
Step-by-step explanation:
We are given the following matrix in the question:
Condition for invertible matrix:
A matrix is invertible if and only if the the determinant is non-zero.
We can find the determinant of the matrix as:
Since the determinant of the given matrix is zero, the given matrix is not invertible.
