Answer:
11.55
Step-by-step explanation:
SOH CAH TOA reminds you ...
Tan = Opposite/Adjacent
The angle at lower left is the complement of 60°, so is 30°. Then the side x satisfies the equation ...
tan(30°) = x/20
Multiplying by 20 gives ...
20·tan(30°) = x ≈ 11.55
Answer:
3.2ft long shadow
Step-by-step explanation:
In this problem we are given a ratio between the tree/shadow and woman/shadow therefore we are given 3 values and 1 unknown then we can use the Rule of Three to calculate the length of the shadow which we will refer to as x. The Rule of Three simply multiplies the diagonal values and divides by the third value in order to get the missing unknown like so...
55ft tall <======> 32ft long shadow
5.5ft tall <======> x ft long shadow
(5.5 * 32) / 55 = 3.2ft long shadow
Finally, we can see that the woman's shadow would be a 3.2ft long shadow
2 is the estimated product the exact answer is 2.83
Answer:
No solution
Step-by-step explanation:
Answer:
The cost of tuition fee after 4 years is $15,149.72.
Step-by-step explanation:
Exponential function:
A= the amount after n years
P= Initial amount
r= rate of increasing
n= time in years
The cost of tuition at a college is $12,000. It is increasing at the rate of 6% each year.
Here, P= $12,000, r= 6%= 0.06, n= 4 years.
=$15,149.72
The cost of tuition fee after 4 years is $15,149.72.
