Find sin X.
a. sin X= 4/5
b. sin X= 3/4
c. sin X= 3/5
d. sin X= 5/4
Answer:
sin X = 4/5
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin X = opp side/ hypotenuse
sin X = 36/45
= 4/5
Let's find the value of sin X,
→ opp/hyp
→ 36/45
→ 4/5
The required answer will be,
→ a. sin X= 4/5
So, option (a) is the answer.

Abel bought a mini hi-fi set for S600.
He sold it to Bob at a loss of 20%.
Bob sold it to Charles and made a profit of 5%. How much did Charles pay for it?
Answer:
$504
$600* .8 = $480
$480 * 1.05 = $504
Step-by-step explanation:
Answer:
Step-by-step explanation:
Abel:
Cost price = $ 600
Loss = 20%
Selling price = [tex]\frac{100-loss}{100}*Cost \ price[/tex]
[tex]= \frac{(100-20)}{100}*600\\\\=\frac{80}{100}*600[/tex]
= 80 * 6 = $ 480
Cost price for Bob = Selling price of Abel = $ 480
Bob's cost Price = $480
Selling price = [tex]\frac{100+Profit}{100}*CP\\\\[/tex]
[tex]= \frac{100+5}{100}*480\\=\frac{105}{100}*480[/tex]
= $ 504
Amount paid by Charles =$ 504

Answer:
108
Step-by-step explanation:
Surface area = total area of net
The net is made up of 2 unique shapes
A square with a side length of 6
The area of a square can be calculated by squaring the side length
6^2 = 36
The area of the square = 36
The net is also made up of 4 triangles
The triangles have a base length of 6 and a height of 6
The area of a triangle can be calculated by using the formula A = (bh) / 2
Where b = base length and h = height
If the triangles have a base length of 6 then b = 6 and if they have a height of 6 then h = 6
So A = 6*6/2
6 * 6 = 32
32/2 = 18
We then multiply that by 4 to get the area of all four triangles
18 * 4 = 72
Finally we add the areas together
72 + 36 = 108
The surface area is 108
According to the rational root theorem what are all potential rational roots of F(x)=9x^4-2x^2-3x+4
Answer:
The answer is
[tex]( + - )(1)( \frac{1}{3} )( \frac{1}{9} )(2)( \frac{2}{3} )( \frac{2}{9} )(4)( \frac{4}{3} )( \frac{4}{9} )[/tex]
Explanation:
Rational root theorem, also called rational root test, in algebra, theorem that for a polynomial equation in one variable with integer coefficients to have a solution (root) that is a rational number, the leading coefficient (the coefficient of the highest power) must be divisible by the denominator of the fraction and
and the constant term (the one without a variable) must be divisible by the numerator.
In f(x), the ratio is
[tex] \frac{4}{9} [/tex]
because 4 is the constant and 9 is leading term
So our factors are
[tex] \frac{4}{9} = \frac{ + - (1)(2)(4)}{ + - (1)(3)(9)} [/tex]

Answer:
2,5; 9,3; 3,1 i think hope it helps :)
Step-by-step explanation:
When crossing over the y axis the x values change their sign ex. -2,5 --> 2,5
What is reflection of (5, 15) across the x-axis?
Answer:
(5 , -15)
Step-by-step explanation:
When you are reflecting over the x-axis, you are flipping the sign of the y-coordinate.
If you are reflecting over the y-axis, then you are flipping the sign of the x-coordinate.
In this case, you are given the point (5 , 15), and you are reflecting over the x-axis, in which case, your answer will be: (5 , -15).
~
Answer:
Step-by-step explanation:
In this question, we are asked to find the point of reflection across the x-axis.
The easiest way to find reflection is to find the equal distance from the current point to the x-axis, then apply it reversely to find the reflected point.
The vertical point from (5, 15) to the x-axis is (5, 0).
Then, we need to find the distance from (5, 15) to (5, 0)
15 - 0 = 15 unitsAs we know the distance from (5, 15) to (5, 0) is 15 units, then we apply this to the other side of the x-axis by subtraction
0 - 15 = -15 unitsTherefore, the reflected point is (0, -15)

Use the properties of logarithms to prove log, 1000 = log2 10.
Given:
Consider the equation is:
[tex]\log_81000=\log_210[/tex]
To prove:
[tex]\log_81000=\log_210[/tex] by using the properties of logarithms.
Solution:
We have,
[tex]\log_81000=\log_210[/tex]
Taking left hand side (LHS), we get
[tex]LHS=\log_81000[/tex]
[tex]LHS=\dfrac{\log 1000}{\log 8}[/tex] [tex]\left[\because \log_ab=\dfrac{\log_x a}{\log_x b}\right][/tex]
[tex]LHS=\dfrac{\log (10)^3}{\log 2^3}[/tex]
[tex]LHS=\dfrac{3\log 10}{3\log 2}[/tex] [tex][\because \log x^n=n\log x][/tex]
[tex]LHS=\dfrac{\log 10}{\log 2}[/tex]
[tex]LHS=\log_210[/tex] [tex]\left[\because \log_ab=\dfrac{\log_x a}{\log_x b}\right][/tex]
[tex]LHS=RHS[/tex]
Hence proved.
A jar contains four yellow balls, six red balls, and eight blue balls. One ball is selected at random.
What is the probability that it is yellow?
Answer:
Step-by-step explanation:
We are trying to see how likely we are to pick a yellow ball. So out of the total number of balls, we have 4 yellow balls (numerator). The total number of balls is 18 and so the probability of picking a yellow ball is 4/18
Answer:
4/18
Step-by-step explanation:
1. you would first take all the number of colored balls and add them together
2. next, you would take the number of yellow balls/ to the total number of balls.
What are ways using coordinate geometry, that I could determine that this is a trapezoid?
One method to see it's a trapezoid is to find the slope of lines BC and AD.
The slope formula is
m = (y2-y1)/(x2-x1)
You should find that BC and AD both have the same slope (of -1), so that means the lines are parallel. That proves we have a trapezoid.
-----------------------
To prove this trapezoid is isosceles, you can use the distance formula
[tex]d = \sqrt{ \left(x_1-x_2\right)^2 + \left(y_1-y_2\right)^2}[/tex]
to find the lengths of AB and CD (the two non-parallel sides). You should find that AB = CD.
Because AB and CD are horizontal and vertical respectively, this means you can simply count out the spaces to find that AB and CD are 3 units each. For any other rotated version of this trapezoid, use the distance formula instead.

5 – 2x = 3 what is x?
Answer: x=1
Step-by-step explanation:
To solve for x, we want to isoate the variable.
5-2x=3 [subtract both sides by 5]
-2x=-2 [divide both sides by -2]
x=1
Now, we know that x=1.
Answer:
X = 1
Step-by-step explanation:
Add 2x to both sides of the equation
5-2x+2x=3+2x
5+0=3+2x
Subtract 3 from both sides of the equation
5-3=3-3+2x
2=0+2x
2x=2
x=2/2
X = 1

a + 1/a= p find a^3 + 1/a^3
(1) p^3 + 3p
(2) 3p
(3) p^3 - 3p
9514 1404 393
Answer:
(3) p^3 -3p
Step-by-step explanation:
(a +1/a) = p . . . . . . . given
(a +1/a)^3 = p^3 . . . . . . . . cube both sides
a^3 +3a^2(1/a) +3a(1/a)^2 +(1/a)^3 = p^3 . . . . . . expand
(a^3 +1/a^3) +3(a +1/a) = p^3 . . . . . . . . . . simplify, group
(a^3 +1/a^3) +3p = p^3 . . . . . . . . . . substitute p for a+1/a
(a^3 +1/a^3) = p^3 -3p . . . . . . subtract 3p from both sides

Which statement are true regarding undefinable terms in geometry
Answer:
A plane has an unlimited number of points.
Step-by-step explanation:
A plane has an unlimited number of points.
An exact solution represents a point's position on the coordinate plane (x, y).
Even though a point has no dimensionality, the second assertion is incorrect.
Because a linear has only one component, length, the third assertion is likewise incorrect.
a: A point has no length or width.
B: a point indicates a location in a coordinate plane.
E: a plane consists of an ifinite plans
F: a line consists of an infinite set of points.
