Answers
Answer:
DC = 1332.95 feet
Step-by-step explanation:
From the figure attached,
Let the measure of DC = h ft
And measure of side BC = a ft
By applying tangent ratio in ΔBCD,
tan(56°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{DC}{BC}[/tex]
= [tex]\frac{h}{a}[/tex]
h = a[tan(56°)] --------(1)
By applying tangent rule in ΔACD,
tan(22°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(22°) = [tex]\frac{DC}{BC+AC}[/tex]
= [tex]\frac{h}{a+2400}[/tex]
h = (a + 2400)tan(22°) ------- (2)
Equating the values of h from equations (1) and (2),
a[tan(56°)] = (a + 2400)tan(22°)
a[tan(56°) - tan(22°)] = 2400[tan(22°)]
1.0785a = 968.6629
a = 899.085 ft
From equation (1),
h = 899.085[tan(56°)]
h = 1332.948
h ≈ 1332.95 ft

A ship sails 9 km due West, then 5 km due South.
Find the bearing of the ship from its initial position.
Give your answer correct to 2 decimal places.
Answers
Answer:
10.29 km
Step-by-step explanation:
Given that,
A ship sails 9 km due West, then 5 km due South.
We need to find the distance of the ship from its initial position. Let the distance be d. We can find it as follows :
[tex]d=\sqrt{9^2+5^2} \\\\d=10.29\ km[/tex]
So, the required distance of the ship from its initial position is equal to 10.29 km.
What is the value of 9x^2 + 13x – 15, if x = 2
Answers
Step-by-step explanation:
Given,
[tex]9 {x}^{2} + 13x - 15[/tex]
and
[tex]x = 2[/tex]
Substitute x = 2 into expression.
[tex]9 {x}^{2} + 13x - 15 = 9( {2}^{2} ) + 13(2) - 15 \\ = 9(4) + 26 - 15 \\ = 36 + 26 - 15 \\ = 62 - 15 \\ = 47[/tex]
Answer:

What is the simple interest earned on an $4,350 investment for 5 years at a rate of 2%?
Answers
Hey!
A = $4,785.00
I = A - P = $435.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year.
Solving our equation:
A = 4350(1 + (0.02 × 5)) = 4785
A = $4,785.00
The total amount accrued, principal plus interest, from simple interest on a principal of $4,350.00 at a rate of 2% per year for 5 years is $4,785.00.
