Answer:
C. Sin 75,5 = y/12
Step-by-step explanation:
This angle can be calculated using the law of sine:
sin(angle)=opposite cathete/hypothenuse
sin(angle)=wall/ladder
In this exercise we want to calculate the height of the ladder, so the equation is changed afterwards.
sin(angle)=wall/ladder
sin(75,5°)=12ft/y
The height y above the ground in feet is ; (C ) sin 75.5 = y / 12
Determine the equation that can be used to determine y
The ladder, the horizontal ground and the vertical height above the ground form a right angle triangle are ;
The vertical height y = opposite
Length of ladder = hypotenuse
Horizontal ground = adjacent.
According to trigonometry, sine of an angle is opposite/hypotenuse
sin 75.5 = y/12.
In conclusion, the height y above the ground in feet is sin 75.5 = y / 12.

-4 - y = -2x
A) y = 4x + 2
C) y = 2x - 4
B) y = -4x + 2
D) y = -2x + 2
Answer:
c

Answer:
The answer is -17.
Step-by-step explanation:
Well since the answer turns out to be a negative, one of the numbers has to be negative.(not all cases but for this one, yes)You have to add 12+5 and you get 17. This has to be a negative because the answer is a negative.

Find the value of a
Answer:
a=60
Step-by-step explanation:
since there are 6 total "a" values (2 angles worth just a, 2 angles worth 2 a)
you divide the total angle number by 6: 360/6=60
a=60
hope this helps!! <3
Please answer this much appreciated.
Answer:
a = [tex]\frac{h-r}{b}[/tex]
Step-by-step explanation:
Given
h = ab + r ( subtract r from both sides )
h - r = ab ( isolate a by dividing both sides by b )
[tex]\frac{h-r}{b}[/tex] = a
A triangle has sides with lengths of 42 millimeters, 43 millimeters, and 58 millimeters. Is it a
right triangle?
Answer:
No
Step-by-step explanation:
42 x 42 = 1764
43 x 43 = 1849
1764 + 1849 = 3613
and the sqaure roof of 3613 is 60.11
60.11 does not equal 58
so no it is not a right triangle

Question 1
Sione just landed a great job as an engineer where he will make $55,000 a year. The
company he will work for guarantees a 3% pay increase each year so it's employees
salaries keep up with inflation. At the end of the 1* year Slone will have made $55,000
dollars.
1. What is the recursive function that will represent this situation?
a. m(t) = m(t - 1) + 0.03, m(1) = 55000
b. m(t) = m(t-1). 0.03, m(1) - 55000
c. m(t) = m(t-1) + 1.03, m(1) - 55000
d. m(t) = m(t-1). 1.03, m(1) = 55000
Answer:
Option (d)
Step-by-step explanation:
If the current salary of Sione is represented by the function m(t - 1),
Next year his salary m(t) gets hike of 3%.
So, the next year salary of Sione will be represented by,
m(t) = m(t - 1) + 3% of m(t - 1)
= m(t - 1) + 0.03 × m(t - 1)
= m(t - 1)(1 + 0.03)
= 1.03m(t - 1)
Since, at the end of year 1 his salary was $55000,
Recursive function will be,
m(t) = 1.03m(t - 1) = 55000
Therefore, Option (d) will be the answer.

Suppose each day that you drive to work a traffic light that you encounter is either green with probability 3/8, red with probability 1/2, or yellow with probability 1/8, independent of the status of the light on any other day. If over the course of five days, G, Y, and R denote the number of times the light is found to be green, yellow, or red, respectively, what is the probability that P[G=2, Y=1, R=2] ? Also, what is the probability P[G=R]? [15%]. Hint: consider sequences possible in a five-day observations
Answer:
a
[tex]P(G = 2 , Y= 1 , R = 2) = 0.13184 [/tex]
b
[tex]P(G = R ) = 0.13919 [/tex]
Step-by-step explanation:
From the question we are told that
The probability of the traffic light being green is [tex]p_g = \frac{3}{8}[/tex]
The probability of the traffic light being red is [tex]p_r = \frac{1}{2}[/tex]
The probability of the traffic light being yellow is [tex]p_y = \frac{1}{8}[/tex]
The number of days of observation is n = 5
Generally the probability distribution function for a multinomial distribution is mathematically represented as
[tex]Pr( X_1 = x_1 \ and \ . . . \ and \ X_k =x_k) = \left \{ {{ \frac{n!}{x_1 ! , . . . x_k !} p_1^{x_1} * \cdots *p_k^{x_k} \ \ \ \ \ \ \ when \ \sum x_i = n } \atop {0 }\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ otherwise \ } \right[/tex]
Generally the probability that P[G=2, Y=1, R=2]
[tex]P(G = 2 , Y= 1 , R = 2) = \frac{5!}{ 2! * 1! * 2!} * [\frac{3}{8} ]^2 * [\frac{1}{8} ]^1 * [\frac{1}{2} ] ^2[/tex]
=> [tex]P(G = 2 , Y= 1 , R = 2) = 0.13184 [/tex]
Generally the probability that P[G=R] is mathematically represented as
[tex]P(G = R ) = P( G = 2 , Y = 1 , R = 2) + P( G = 0 , Y = 5 , R = 0)+ P( G = 1 , Y = 3 , R = 1)[/tex]
Here
[tex] P( G = 0 , Y = 5 , R = 0) = \frac{5!}{ 0! * 5! * 0!} * [\frac{3}{8} ]^0 * [\frac{1}{8} ]^5 * [\frac{1}{2} ] ^0[/tex]
[tex] P( G = 0 , Y = 5 , R = 0) = 0.0000305176 [/tex]
Also
[tex] P( G = 1 , Y = 3 , R = 1)= \frac{5!}{ 1! * 3! * 1!} * [\frac{3}{8} ]^1 * [\frac{1}{8} ]^3 * [\frac{1}{2} ] ^1[/tex]
[tex] P( G = 1 , Y = 3 , R = 1)= 0.0073242 [/tex]
[tex]P(G = R ) = 0.13184 + 0.0000305176+ 0.0073242 [/tex]
[tex]P(G = R ) = 0.13919 [/tex]
