Answer:
132.7 feet.
Step-by-step explanation:
tan 37 = height of cliff / distance of the ship
= 100/d
d = 100/tan37
= 132.7 feet.
. If a = 120°, find the measure of angles b, c and d.
Explain your reasoning.
Find the measure of the missing angles.
133°
b =
C=
Answer:
<b = 133
<c = 47
Step-by-step explanation:
<b and 133 are vertical angles and vertical angles are equal
<c and 133 form a straight line so they add to 180
<c+133 = 180
<c = 180-133
<c =47

Factor the following expression completely. 16x^5-x^3
Answer:
x³ (4x + 1)(4x - 1)
Step-by-step explanation:
Answer:
x^3 (4x-1)(4x+1)
Step-by-step explanation:
16x^5-x^3
Factor out x^3
16* x^2*x^3 - x^3
x^3(16x^2 -1)
The term inside the parentheses is the difference of squares
a^2 - b^2 = (a-b)(a+b)
x^3 ( (4x)^2 -1^2)
x^3 (4x-1)(4x+1)
What is the volume of a sphere with a radius of 49.5 in, rounded to the nearest tenth of a cubic inch?
Answer:
Below
Step-by-step explanation:
To find the volume of a sphere you can use this formula!
V = 4/3πr^3
Plugging in the values....
V = 4/3π(49.5)^3
V = 5.08047 × 10^5
V = 5.1 x 10^5 in^3
If you wanted to write this is standard form it would be
V = 508047 in^3

Function that is similar to exponential.
Option (A) is correct.
What is exponential decay?Exponential decay describes the process of reducing an amount by a consistent percentage rate over a period of time. It can be expressed by the formula [tex]y=a(1-b)^{x}[/tex] wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.
We can observe that

The cityscape bike path is 2 2/3 times longer than the bay view bike path. What is the length of the cityscape bike path?
The complete version of the question is attached below :
The length of Cityscape Bike Path is [tex]3 \frac{1}{9} miles[/tex]
Given that :
Cityscape Bike Path is [tex]2 \frac{2}{3}[/tex]
times longer than Bay View Bike Path
Length of Bay View Bike Path = [tex] \frac{7}{6} miles[/tex]
Hence, to compute the length of Cityscape Bike Path :
Cityscape Bike Path = [tex]2 \frac{2}{3} \times [/tex] Length of Bay View Bike Path
Therefore, length of Cityscape Bike Path =
[tex]2 \frac{2}{3} \times \frac{7}{6} [/tex]
Length of Cityscape Bike Path =
[tex] \frac{8}{3} \times \frac{7}{6} = \frac{56}{18} = 3 \frac{1}{9} miles[/tex]
Hence, the length of Cityscape Bike Path is [tex]3 \frac{1}{9} miles[/tex]

Help with this question please!
Answer:
Step-by-step explanation:
6cos^2(x) + 7cos(x) +2 = 0
Call cos(x) = y to change this to something a little bit more familiar.
6y^2 + 7y + 2 =0
This equation is a quadratic. Solve it first. Then we'll go back to solving for cos(x)
This equation factors into 2 possible answers
(3y + 2)(2y + 1) = 0
3y + 2 = 0
3y = - 2
y = - 2/3
2y + 1 = 0
2y = - 1
y = - 1/2
Now let's start with
cos(x) = - 1/2
That means that x is in quadrant two or three.
cos-1(1/2) = 60 degrees.
Quad 2: x = 180 - 60 = 120
Quad 3: x = 180 + 60 = 240
Now cos(x) = - 2/3
cos-1(2/3) = 48.19
Quad 2: x = 180 - 48.19 = 131.81
Quad 3: x = 180 + 48.19 = 228.19

if 4 is a root of x^2- kx+12=0 , then the value of k and the other roots are what?
Answer:
k=7
Other root=3
Step-by-step explanation:
If x=4 is a root of the given equation, then it satisfies the given equation.
4^2-k(4)+12=0
We can solve this equation for k.
16-4k+12=0
28-4k=0
28=4k
28/4=k
7=k
So the equation is x^2-7x+12=0
Factor form is (x-3)(x-4)=0 since-3(-4)=12 and -3+-4=-7.
This implies x=3 and x=4 are roots.

what is the one solution for the linear equations y=3x-5 and y=-3x+7
Answer:
y=1 and x=2
Step-by-step explanation:
Add the two linear equation and you will have 2y=2, y=1. Plugging this in any equation, we have x=2
Answer:
The solution is (2,1)
Step-by-step explanation:
Set the two equations equal
y=3x-5 and y=-3x+7
3x-5 = -3x+7
Add 3x to each side
3x-5+3x = -3x+7+3x
6x-5 = 7
Add 5 to each side
6x-5+5 = 7+5
6x = 12
Divide by 6
6x/6 = 12/6
x=2
Now find y
y =3x-5
y=3(2)-5
y = 6-5
y=1
The solution is (2,1)

Triangle says the sum of any 2 sides is bigger than the third.
Assume a,b,c are side measurements of a triangle.
So if you know two sides a and b then the third number, c, is such that |b-a|<c<a+b.
So just add the given numbers and find the positive difference.

Domain is [tex]x \ge d[/tex]
You'll check the box labeled "x", the box labeled [tex]\ge[/tex] and the box labeled "d". So you'll have 3 boxes checked.
=======================================================
Explanation:
We cannot have a negative number under the square root, and get some real number output. For example, the result of [tex]\sqrt{-4}[/tex] isn't a real number.
That means we need to have the "x-d" under the square root to be 0 or larger.
[tex]x-d \ge 0\\\\x-d+d \ge 0+d\\\\x \ge d[/tex]
The domain is [tex]x \ge d[/tex] telling us that x = d is the smallest x value we can plug in
So that's why we check off the box labeled "x", the box labeled [tex]\ge[/tex] and the box labeled "d" as shown below.
