The molarity of the resulting solution is 3.99 × 10⁻⁴ M. The correct option is the third option 3.99 × 10⁻⁴ M
Molarity of a solutionFrom the question, we are to determine the molarity of the resulting solution
From the given information,
Number of moles = 5.99 × 10⁻⁶ mol
Volume = 1.50 × 10⁻² L
Using the formula,
Molarity = Number moles / Volume
∴ Molarity = (5.99 × 10⁻⁶) / (1.50 × 10⁻²)
Molarity = 3.99 × 10⁻⁴ M
Hence, the molarity of the resulting solution is 3.99 × 10⁻⁴ M. The correct option is the third option 3.99 × 10⁻⁴ M

The measure of the side RS from the figure is 4.6 units
Midpoint theorem of a trapezium
The given figures are trapezoid. Given the following parameters
PQ = 4RS
We need to determine how PR is equivalent to 4.6
Since PQ = 18.4 from the diagram, hence;
18.4 = 4RS
RS = 18.4/4
RS = 4.6 units
Hence the measure of the side RS from the figure is 4.6 units

find the value of x
Answer:
x=5
\
Step-by-step explanation:
Answer:
x = 0
Step-by-step explanation:
Line segment UV and line segment VW together form line segment UW.
UV + VW = UW
(5 + x) + (6) = (2x + 11)
5 + x + 6 = 2x + 11
x + 11 = 2x + 11
x + 11 - 11 = 2x + 11 - 11
x = 2x
x - x = 2x - x
0 = x
You can also verify the result by substituting x with our result 0.
5 + x + 6 = 2x + 11
5 + (0) + 6 = 2(0) + 11
11 + 0 = 0 + 11
11 = 11
Left side of the equation is the same as the right side of the equation, therefore the result x = 0 is correct.
Consider the equation. Which graph shows a line that is perpendicular to the line defined by the given equation? A.

In a linear graph line diagram, A line passes through (2, minus 4) and (0.5, 2) which intersects the x-axis at 1 unit and the y-axis at minus 4 units.
The graph second represents the line that is perpendicular to the line y = 4x - 2 option (B) is correct.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

The complete question is:
Consider the equation y = 4x - 2 Which graph shows a line that is perpendicular to the line defined by the given equation?
Please refer to the attached picture.
The given line:
y = 4x - 2
The slope of the line m = 4
The slope of the line which is perpendicular to the above line:
M = -1/4 = -0.25

If 1-cosA = 1/2 , Then find the value of sinA.
Step-by-step explanation:
Given :
1- cosA = 1/2
or, CosA = 1 -1/2
Therefore ; CosA = 1/2 = b/h
According to the Pythagoras theorem,
P = root under h^2 - b^2
= root under (2)^2 - (1)^2
= root under 4 -1
= root 3
Again,
SinA = P/h
= root 3 / 2

Answer:
Step-by-step explanation:
Ok so you are given the values of the slope-intercept form with m being the slope and b being the y-intercept. So since b is equal to -1 you want to plot a point at (0, -1) since that is the y-intercept (when x = 0). The next thing you want to do is look at the slope, which is essentially saying each time x increases by 5 the y-value decreases by 4 or in other words rise/run which is negative which is why you're going down. So from the point (0, -1) go forward 5 units and go down 4 units which should lead you to (5, -5) and the third point you can plot is by going backwards instead of forwards. So instead of every time x increases by 5 y decreases by 4 you're going to do the inverse. Every time x decreases by 5, y is going to increase by 4. So by doing this from the y-intercept (0, -1) you should go backwards 5 units and up 4 units which should lead you to (-5, 3). And then now just draw a line that goes through all those three points. Hope that helps :)
Which graph represent f of x equals square root of the quantity x plus 2 end quantity minus 3?

The graph of the function:
[tex]f(x) = \sqrt{x + 2} - 3[/tex]
Is the last graph (bottom graph of the second image).
Which graph represents the given function?
Here we have the function:
[tex]f(x) = \sqrt{x + 2} - 3[/tex]
Remember that the argument of a square root must be zero or larger, then the minimum of the domain is the value of x such that:
x + 2 = 0
x = -2
Then the function starts at:
[tex]f(-2) = \sqrt{-2 + 2} - 3 = -3[/tex]
Then the graph should start at (-3, 2).
We can also identify another point by evaluating in x = 2.
[tex]f(2) = \sqrt{2 + 2} - 3 =2 - 3 = -1[/tex]
So the function also passes through (2, - 1).
Notice that the only graph that contains these two points is the last graph (the bottom graph on the second image), so that is the correct option.

The function is h(t) = 7/4 cos π/3 t + 9/4,
What is function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
As, h(t) = x cos π/3 t +y
when t= 0, h(t) = 4
when t= 3, h(t) = 0.5
So,
x cos π/3 *0 +y=4
x cos π/3 *3 +y=0.5
and, x+ y = 4, -x+ y =0.5
Now,
2y= 4.5
y= 9/4
and, x= 4-9/4= 7/4.

Simultaneous equation find x and y
Answer:
x = 27, y = 6
Step-by-step explanation:
x - 2y = 15
x - 4y = 3 (rearranged the orginal equation)
x - 2y = 15
- x - 4y = 3
___________
2y = 12
y = 6
Plug this value in any original equation
x - 2(6) = 15
x = 27
x and y of the simultaneous equation are 27 and 6 respectively.
Given,
x - 2y = 15
x - 3 = 4y
Here,
Equations:
x - 2y = 15
Rearranged the original equation
x - 4y = 3
Now subtract both equations,
x - 2y = 15
x - 4y = 3
⇒2y = 12
y = 6
Plug this value in any original equation
x - 2(6) = 15
x = 27
Thus the solution of system of equation is x = 27 and y = 6.

The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. The height of the triangle is 6.2172 cm.
What is Sine (Sinθ)?The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,
Sin(θ) = Perpendicular/Hypotenuse
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The hypotenuse is the longest side of the triangle.
In the given diagram let the centre of the circle be represented by O, while the point at which line segment h and the circle intersect be represented by B. Also, the point at which the 90° angle is formed is represented by A.
Now, in the ΔABO, for the ∠AOB, the sine ratio of the trigonometric function can be written as,
sin(θ) = perpendicular / Hypotenuse
sin(51°) = AB / OB
sin(51°) = h/ 8 cm
8cm × sin(51°) = h
h = 6.2172 cm
Hence, the height of the triangle is 6.2172 cm.
