Answer:
cos x = 0.5
Step-by-step explanation:
Using the trigonometric identity
cot x = 
Given
sin x cot x = 0.5, then
sin x × = 0.5 ← cancel sin x on numerator/ denominator
cos x = 0.5
Answer:
it takes approximately 11 years and 3 months (11.4 years) for Belinda's investments to double.
Step-by-step explanation:
To calculate the time it takes for Belinda's money to double, we will use the simple interest formula as shown below:
Simple interest = P × R × T
where:
P = principal = $800
R = Rate in decimal = 8.75% = 0.0875
T = time = ???
simple interest = $800 ( her money doubles)
∴ 800 = 800 × 0.0875 × t
800 = 70 × t
∴ t = 800 ÷ 70 = 11.4 years. (11 years and 3 months)
Therefore after approximately 11 years and 3 months, Belinda's investments doubles
The statement that is true about the dot plots is: Range for Week 1 equals range for Week 2.
<h3>What is the Range of a Data Set?</h3>
Range is simply the difference between the highest data point and the lowest data point in a data set.
Range for Week 1:
Range = 89 - 62
= 27
Range for Week 2:
Range = 89 - 62
= 27
The sentence of median and mean doesn't satisfy the situation.
Hence, Range for Week 1 equals range for Week 2.
