Answer:
49° approx.Step-by-step explanation:
Step one:
given
The distance of the ship from the base= 1.3km
Height of the cliff= 150m= 1.5km
Step two:
Required
angle of depression
Applying SOH CAH TOA
The opposite is to the angle of depression is the height which is 1.5km
The distance of the ship from the foot of the cliff is the adjacent which is 1.3km

4x -2y = 2
2x +2y = 16
Answer:
x = 3
y = 5
Step-by-step explanation:
we can add these equations together
4x - 2y +2x + 2y = 18
6x = 18
x = 3
to find y
6 + 2y = 16
2y = 10
y = 5

Answer:
See below
Step-by-step explanation:
A > [tex]Sin^{2} x + cos^{2} x = 1 \\[/tex]
Divide both side by sin^2 x , and we get
[tex]\frac{sin^2 x}{sin^2 x} + \frac{cos^2 x}{ sin^2 x} = \frac{1}{sin^2 x}[/tex]
[tex]1+ cot^2 x= cosec^2 x[/tex]
Subtracting cosec^2 x from both sides we get
[tex]Cosec^2 x - cot^2 x = 1[/tex]
B>lets break tan θ into its components tan θ = sin θ / cos θ and cot θ = 1/ tan θ
Tan θ + cot θ= Sin θ/cos θ + cos θ/ sin θ = sin^2 θ + cos^2 θ / sin θ cos θ= 1/ sin θ cos θ = sec θ cosec θ
Answer:
Step-by-step explanation:
A >
Divide both side by sin^2 x , and we get
Subtracting cosec^2 x from both sides we get
B>lets break tan θ into its components tan θ = sin θ / cos θ and cot θ = 1/ tan θ
Tan θ + cot θ= Sin θ/cos θ + cos θ/ sin θ = sin^2 θ + cos^2 θ / sin θ cos θ= 1/ sin θ cos θ = sec θ cosec θ
Kermit flipped a coin 20 times. The coin landed on tails six times. Which best describes what would likely happen if Kermit flipped the coin another 80 times?
Answer:
24 of those times would be tails.
Step-by-step explanation:
Because if you flip it 20 times and it lands on tails 6 times, you just have to add 20+20 6+6 so then it's 40 flips and 12 tails. 60 times and 18 tails 8p times and 24 tails.

solve 70=-2.5x (one-step equation) what is this answer?
Answer:
Step by step and hope this helps
70=−2.5x
Step 1: Flip the equation.
−2.5x=70
Step 2: Divide both sides by -2.5.
−2.5x−2.5=70−2.5
x=−28

2r +9r + 10 = 0
Answer:
[tex]r= -\frac{10}{11}[/tex]
Step-by-step explanation:
[tex]2r+9r+10=0\\[/tex]
combine 2r and 9r
[tex]11r+10=0[/tex]
subtract 10 on both sides
[tex]11r=-10[/tex]
[tex]r= -\frac{10}{11}[/tex]
The ratio of the measures of the sides of a triangle is 21:8:14. The perimeter is 215 feet, find the length of each side
how can you find a common denominator for 1/3 and 1/5
Answer:
15
Step-by-step explanation:
What is the length of the shortest side if the perimeter of the rectangle is 56 inches?
Answer: Length of Shortest Side = 12 inches
Step-by-step explanation: Length of Shortest Side = L = 3x
Length of Longest Side = W = 5x-4
Condition:
2L+2W = Perimeter
2(3x)+2(5x-4) = 56
6x+10x-8 = 56
16x-8 = 56
Adding 8 to both sides
16x = 56+8
16x = 64
Dividing both sides by 14
=> x = 4
Now,
Length of the Shortest Side = L = 3(4) = 12 inches
Length of the Longest Side = W = 5(4)-4 = 16 inches

Solve for x:
7x + 5 + x - 3 + x = 5
Answer:
x=1/3
Step-by-step explanation:
9x+5-3=5
9x=3
x=1/3
Answer:
x=1/3
Step-by-step explanation:
7x + 5 + x - 3 + x = 5
-5 -5 (rewrite)
7x + x - 3 + x = 0
7x + x + x = 9x (collect like terms) (rewrite)
9x - 3 = 0
9x = 3
(divide both sides by 9)
x= 1/3

Form a polynomial in factored and standard from that has a degree of 3 and zeros: 2 - i, and
1.
Answer:
(x - 2 + i)(x - 2 - i)(x - 1)x^3 -5x^2 + 9x - 5Step-by-step explanation:
In order to have rational polynomial, it has to have 2 + i as third zero.
Polynomial in factored form:
(x - (2 - i))(x - (2 + i))(x - 1) =(x - 2 + i)(x - 2 - i)(x - 1)Polynomial in standard form:
(x^2 - 2x - ix - 2x + 4 +2i + ix - 2i -i^2)(x - 1) =(x^2 - 4x + 4 + 1)(x - 1) =(x^2 - 4x + 5)(x - 1) =x^3 - x^2 - 4x^2 + 4x + 5x - 5 =x^3 -5x^2 + 9x - 5Write the following linear function in slope intercept form.

If h(x)=|5x−17|, the value of h(3) is
h(3) = |5(3)-17|
h(3) = |15-17|
h(3) = |-2|
h(3) = 2 ---- | - a | = | a | -----------
Answer:
h(3)=2
Step-by-step explanation:
h(x)=l5x-17l
