Answer: 7 years
Step-by-step explanation:
Given the formula for simple interest as
Principal × Rate × Time
To find Time is therefore 100 × Interest/ Principal x Rate
From the above question,
Principal is given as 600;
Interest is 294 and
Rate is 7%
Slot the values into the formula:
100 × 294/ 600 x 7
= 29400/4200
=7
Therefore, Time (T) is 7 years

The answer that you have written for 4 and 5 is correct
Answer:
K = 12
Step-by-step explanation:
10 Cos 30° – 3 Tan 60°
The above expression can be simplified as follow:
10 Cos 30° – 3 Tan 60°
Recall:
Cos 30° = √3/2
Tan 60° = √3
Therefore,
10 Cos 30° – 3 Tan 60°
10 (√3/2) – 3(√3)
5√3 – 3√3
(5 – 3) √3
2√3
To write the above expression 2√3 in the form √K, we simply do the following:
2√3
Find a number, such that the square root of the number will result to 2. The number is 4 as shown below
√4 = 2
Next, replace 2 with √4 in the expression above
2√3
= √4 × √3
= √(4 × 3)
= √12
Therefore,
2√3 = √12
Comparing √12 with √K,
√12 = √K
K = 12
Answer: B) False
A counter-example would be the cubic polynomial y = x^3 which doesn't have a max or a min. The graph stretches forever in both directions (up and down) indicating that the range is the set of all real numbers.
