I think you need to use the SoHCaHToA method here.
S means sin
C means cos
T means tan
O means opposite
H means hypotenuse
A means adjacent
The hypotenuse is the longest side in a right angled triangle.
The adjacent is the side between the angle and the right angle.
The opposite is the side that is left.
If you have the value of the opposite cross all of the o's out. The same with the other sides. If only one type of letter is crossed out, cross out the type of letter that stands for the length you want to find. The part of the word with two crosses tells you what function to use (sin, cos or tan)
In this example, the function used will be sin.
sinx°=o÷h
cosx°=a÷h
tanx°=o÷a
since we are using sin, the formula we will use is :
sinx°=o÷h
Then you plug in what you know.
sin30°=30÷h
h=30÷sin30°
h=60ft
If there was a case when you needed to work out an angle, inverse sin, or cos, or tan would be used.
Answer:
Step-by-step explanation:
First digit 2,3,4,5 = 4 different digits.
Second digit 2,3,4,5 = 4 different digits.
Third digit = 1,2,3,6,7,9 = 6 different digits.
Total number of possibilities = 4*4*6 = 96
Answer:
Step-by-step explanation:
If a given variable varies inversely with another variable, an increase in the value of the given variable would cause a corresponding decrease in the value of the other variable. Also, a decrease in the value of the given variable would cause a corresponding increase in the value of the other variable.
If y varies inversely with x, we would introduce a cost of variation, k so that the expression becomes
y = k/x
When y = 0.25, x = 8
Substituting into the expression above, it becomes
0.25 = k/8
k = 0.25 × 8
k = 2
The inverse variation function is
y = 2/x
A) 43,000
10^3 is the same as 10,000
multiply 10,000 by 4.3=43,000
hopes this helps
False.
To determine the standard deviation (and the same is true for the mean) you need to know how many times each number was repeated.
