Tan(35)=ck/cd
0.7= ck/3
ck=2.1
Tan(65)=cj/cd
2.1=cj/3
cj=6.3
jk=6.3-2.1=4.2
Answer: $5000; $2000
Step-by-step explanation:
Simolw interest is calculated as: PRT/100
where,
P = principal
R = rate
T = time
Let the money in the 4-yr cd be represented by y.
Since rate = 5.2%
Simple interest = (y × 5.2 × 4)/100
Since he invested $3000 less in a 18-month CD, Let the money in the 18-month CD be represented by (y - $3000).
Then, S.I = [(y - $3000) × 3 × 1.5]/100
The total interest = $1130
We then equate the two simple interest together. This will be:
= (y × 5.2 × 4)/100 + (y - $3000) × 3 × 1.5]/100 = $1130
0.208y + 0.045(y - $3000) = $1130
0.208y + 0.045y - $135 = $1130
0.253y = $1130 + $135
0.253y = $1265
y = $1265/0.253
y = $5000
The money invested in 4-yr CD = $5000
The money invested in the 18-month CD = $5000 - $3000 = $2000
Answer:
r = 3.75
Step-by-step explanation:
Using Pythagoras' identity in the right triangle ABC
AC² = BC² + AB²
(r + 6)² = r² + 9²
r² + 12r + 36 = r² + 81 ( subtract r² from both sides )
12r + 36 = 81 ( subtract 36 from both sides )
12r = 45 ( divide both sides by 12 )
r = 3.75

Answer:
A - Difference in tides for location C is 6.9 feet and high tide for location A is 8.2 feet.
B - Value of low tide in location D is -0.64 feet.
Step-by-step explanation:
Part A: We are given,
The table showing the difference between high and low tides.
The difference in tides for location C = 7.34 - 0.44 = 6.9
So, the difference in tides for location C is 6.9 feet.
Also, i.e. i.e. i.e. x = 8.2
So, the high tide for location A is 8.2 feet.
Part 2: We are given, the mean of the low tides for the 4 locations is -0.54
Let, 'x' feet be the value of the low ride in location D.
That is,
That is,
That is,
That is,
That is,
That is, x = -0.64 feet
Hence, the value of low tide in location D is -0.64 feet.
