Answer: The figure drawn by Alan is a rhombus.
Step-by-step explanation:
Given: Allan drew a polygon with 4 sides and 4 angles with two properties:-
- All four sides are equal.
- None of the angles are right angles.
We know that only a rhombus is a flat shape with 4 equal straight sides and 4 angles .All sides have equal length. Its angles need not to be right angle.
Therefore, the figure drawn by Alan is a rhombus.
Answer:
Step-by-step explanation:
We have the product, 
.
It is known that,
'When we multiply a scalar with a matrix, the scalar is multiplied by each element of the matrix'.
So, we get,
.
⇒ 
⇒
So, the resulting product is .

Answer:
$45
Step-by-step explanation:
We are given the following information;
- Money invested (Principal) is $300
- Rate of interest is 5% per annum
- Time the money is invested is 3 years
We need to determine the amount of interest the money will earn after three years.
- Simple interest is calculated by the formula;
- Simple interest =(PRT) ÷ 100, Where P is the principal amount, R is the rate of interest and T is the time.
Therefore, in this case;
Simple interest = ($300 × 5 × 3) ÷ 100
= $45
Thus, the money invested earned a simple interest of $45
Answer:
A. 0
Step-by-step explanation:
The value of the discriminant is ...
b² -4ac = (-3)² -4(1)(4) = 9 - 16 = -7
The negative discriminant means the roots will be complex.
There are 0 real solutions.
