In triangle ABC, angle C is a right angle. Find the value of the trig function.
Find the tan(A) if c = 10 and b = 8
Answer:
[tex]tan(A) = \frac{3}{4}[/tex]
Step-by-step explanation:
Given
Right-angled triangle ABC
[tex]c = 10[/tex] [tex]b = 8[/tex]
Required
Calculated tan(A)
First, we calculate the length of a.
Since the triangle is right-angled at C, then c is the hypotenuse and side a is the opposite of A.
So, we have:
[tex]c^2 = a^2 + b^2[/tex]
[tex]10^2 = a^2 + 8^2[/tex]
[tex]100 = a^2 + 64[/tex]
[tex]a^2 = 100 - 64[/tex]
[tex]a^2 = 36[/tex]
Take square roots
[tex]a = 6[/tex]
So:
[tex]tan(A) = \frac{a}{b}[/tex]
[tex]tan(A) = \frac{6}{8}[/tex]
[tex]tan(A) = \frac{3}{4}[/tex]

Step-by-step explanation:
find the value of x (6x + 1) (9x-23)
Answer:
Step-by-step explanation:
Alright we are going to be using F.O.I.L
(6x + 1) (9x-23) Apply F.O.I.L
6x*9x+6x(-23)+1*9x+1*(-23) Remove parenthesis
6x*9x+6*23x+1*9x+1*23
Step 2
6x*9x+6*23x+1*9x+1*23
So you simplify
54x^2-129x-23
Your Simplified answer is 54x^2-129x-23
The value of expression x (6x + 1) (9x-23) is 54x³-129x²-23x.
What is an algebraic expression?An algebraic expression is consists of variables, numbers with various mathematical operations,
The given expression is,
x (6x + 1) (9x-23)
To solve this expression, Simplify bracket terms,
(6x + 1) (9x-23) = 54x²+9x-138x-23
= 54x²-129x-23
Further,
x (6x + 1) (9x-23) =x(54x²-129x-23)
= 54x³-129x²-23x
The expression x (6x + 1) (9x-23) can be solved as 54x³-129x²-23x.

If X is a normal random variable that has mean mu = 20 and standard deviation sigma = 2, the standardized value of X = 16 is
Answer:
The standardized value is -2
Step-by-step explanation:
Given
[tex]mu = 20[/tex] -- mean
[tex]\sigma = 2[/tex] --- standard deviation
Required
Determine the standardized value of X = 16
The standardized value (S) is calculated using:
[tex]S = \frac{X - mu}{\sigma}[/tex]
This gives:
[tex]S = \frac{16 - 20}{2}[/tex]
[tex]S = \frac{- 4}{2}[/tex]
[tex]S = -2[/tex]
The standardized value is -2
Solve for the variable indicated
-4x-8y=36 solve for x
Answer:
x = -2y - 9
Step-by-step explanation:
First isolate the variable by putting the x on a side by itself.
-4x=36+8y (8y becomes positive when it changes sides)
Then divide the entire equation by -4 to make the x stand alone.
x = -9 -2y
Some teachers prefer the variables at the beginning of the equations so it could also read
x = -2y - 9
Hello there!
Question:-
[tex]-4x-8y=36[/tex]
We need to find the value of x.
Solution:-
[tex]\sf \longmapsto-4x-8y=36[/tex]
Firstly, Add 8y to both sides :-
[tex]\sf \longmapsto \: - 4x - 8y+8y=36+8y[/tex]
On Simplification:-
As (-) and (+) equals to (-),It Will be 8y-8y.Answer would be 0.
[tex]\sf \longmapsto \: - 4x - 0 = 36 + 8y[/tex]
[tex]\sf \longmapsto \: - 4x = 8y + 36[/tex]
Then, Divide both sides by -4:-
[tex]\sf \longmapsto \: \dfrac{4x}{ - 4} = \dfrac{8y + 36}{ - 4} [/tex]
On Simplification:-
[tex]\sf \longmapsto \: x = - 2y - 9[/tex]
______________________________________
Henceforth the value of x is :-
[tex] \boxed{\tt \: x = - 2y - 9}[/tex]

I hope this helps!

The percentage of deaths occurred in 2004 is 27.77%.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
We have the table that contains the total number of deaths worldwide as a result of earthquakes from 2000 to 2012.
In 2004,
228802 deaths occurred.
And the total number of deaths = 823756
To find the percentage:
Let n be the required percentage.
228802 = n x 823756 / 100
n = 228802 x 100 / 823756
n = 27.77%
Therefore, the percentage is 27.77%.

a millipede has 14 more legs than a caterpillar. together they have 46 legs. how many legs does a caterpillar have?
Answer:
32
Step-by-step explanation:
46-14=32 so therefore, a Caterpillar has 32 legs.
The caterpillar has [tex]16[/tex] legs.
Millipede:The class Diplopoda, from which the word "millipede" is derived, is a group of arthropods that are distinguished by having two pairs of jointed legs on most body segments. Two single segments are joined to form each double-legged segment.Caterpillar:Members of the order Lepidoptera in the larval stage are known as caterpillars (the insect order comprising butterflies and moths).The word's use is arbitrary, as it is with most common names, as caterpillars are another term for sawfly larvae (suborder Symphyta).Larvae of symphylans and lepidopterans exhibit eruciform body forms.Solution -Let, the caterpillar's legs be [tex]x[/tex].
[tex]x+(x+14) = 46\\2x+14=46\\2x=46-14\\2x=32\\x=\frac{32}{2} \\x=16[/tex]
Therefore, the caterpillar has [tex]16[/tex] legs.

Thank you
Answer:
We can break this figure up into 3 rectangles. The 3x6 one, the 6x9 one, and the 15x12 one. Then, to find the area of the figure all we need to do is multiply and add them up. 3*6=18, 6*9=54, and 15*12=180. Then, we do 18+54+180= 252 sqaure inches, so your answer would be the first option.
