A lifeguard sitting in a tower 10ft off the ground spots swimmer in trouble at a 55 angle of depression. If the lifeguard tosses a ring in a 15ft rope to the swimmer, can the ring reach the swimmer? Finish solving the problem below to determine your answer
Answers
Based on the given parameters, the 15 ft rope will reach the swimmer
How to determine if the ring reach the swimmer?From the question, we have the following equation:
sin 55 = 10/x
Multiply both sides of the equation by x
x * sin 55 = 10/x * x
Evaluate the product
x * sin 55 = 10
Divide both sides by sin 55
x = 10/sin 55
Evaluate sin 55
x = 10/0.8192
Evaluate the quotient
x = 12.21
From the question, the lifeguard tosses a ring in a 15ft rope to the swimmer
15 is greater than 12.21
This means that the 15 ft rope will reach the swimmer
Hence, the 15 ft rope will reach the swimmer

Can 4(x+2)=10 equal 0
Answers
Answer:
x = 0.5
Step-by-step explanation:
The given expression is :
4(x+2) = 10
Using commutative property at LHS.
4x+8 = 10
Subtract 8 from both sides.
4x+8-8 = 10-8
4x = 2
x = (1/2) = 0.5
So, the value of x is equal to 0.5 instead of 0. Hence, the given expression cannot be equal to 0.

Solve and graph the inequality.
7n - 1 > 76
Answers
Answer:
n>11
Step-by-step explanation:
I don't know how to graph this answer, sorry!
The solution of the inequality 7n - 1 > 76 gives n < 11 along with the graph.
Given Inequality:
7n - 1 > 76
To solve the inequality add 1 on both side of inequality as
7n - 1 + 1 > 76 + 1
7n > 77
Now, divide the inequality by 7 as
7n/ 7 > 77/ 7
n > 11.
Therefore, the solution is n > 11.

Rule: multiply by 2 Pattern: 3,6,12,24,48 Observation: Observation = something similar about the numbers
Answers
Step-by-step explanation:
This numerical sequence corresponds to a geometric progression, which occurs when there is a multiplication of the sequence numbers for a common reason whose result will always be the successor number of the numerical sequence.
Like for example:
3,6,12,24,48
The common reason for the geometric progression is the number 2, so the first term of the sequence multiplied by 2 will be equal to the second term of the sequence and so on:
3x2 = 6
6x2 = 12
12x2 = 24
24x2 = 48
It is necessary to emphasize that the ratio of a geometric progression will always be constant and will always be a number other than zero.
