I need questions 10 , 13 , 15 , and 16 solved with steps and graph
10. |x - 4| - 4 = 1/2x
⇒ Multiplying by 2,
2 |x - 4| - 8 = x
So, x - 4 = (x + 8)/2
= -(x + 8)/2
When,
x - 4 = (x + 8)/2
2x - 8 = x + 8 (Multiplying by 2)
2x - x = 8 + 8 (Adding 8 and subtracting x to both sides)
x = 16
When,
x - 4 = - (x + 8)/2
2x - 8 = -x - 8 (Multiplying by 2)
2x + x = -8 + 8 (Adding 8 and x to both sides)
3x = 0
x = 0
Hence, the solution is x = 16 and x = 0.
13. (3/4)x = 2x - 10
⇒ Subtract 2x from both sides.
-5x/4 = -10
Multiply both sides by 4/(-5).
(-5x/4)×4/(-5) = -10 × 4/(-5).
x = 8 is the solution of the equation.
15. x² - 7x - 8 > 0
⇒ Solve the quadratic equation by splitting the middle term,
x² - 8x + x - 8 > 0
x(x - 8) + 1(x -8) > 0
(x + 1)(x- 8) > 0
-1 and 8 are the critical points of the inequality.
x < -1 and x > 8 are the solutions of the inequality which are represented by the shaded red region in the graph.
16. x - 5 > - 2x + 4
⇒ Adding 2x to both sides.
3x - 5 > 4
Adding 5 to both sides.
3x > 9
Divide both sides by 3.
x > 3 is the required solution represented by blue shade region in the graph.

Given sin 60degrees √ 3/2 find cos 60°
cos 60°
Step-by-step explanation:
if I understand you correctly, then you got
sin(60°) = sqrt(3/2)
and now we have to find cos(60°) based on that.
but : sin(60°) = sqrt(3/4) = sqrt(3)/2
I will continue with that.
one major observation with the trigonometric functions in a norm circle (radius = 1) is that sine and cosine are the legs of a right-angled triangle.
the radius at the angle is the Hypotenuse.
and so, Pythagoras applies
c² = a² + b²
c is the Hypotenuse, a and b are the legs.
so,
radius² = sin²(x) + cos²(x)
and because radius = 1
1² = 1 = sin²(x) + cos²(x)
in our case
1 = sin²(60) + cos²(60)
1 = (sqrt(3)/2)² + cos²(60) = 3/4 + cos²(60)
cos²(60) = 1 - 3/4 = 1/4
cos(60) = sqrt(1/4) = 1/2

Find the price elasticity of the demand function as a function of p.
1. q=D(p)=600-3p
A)E(p)= p/p-200
B)E(p)= p/600-3p
C)E(p)= p/200-p
D)E(p)= p(200-p)
The price elasticity of the demand function as a function of p is C. E(p)= p/200-p
How to illustrate the information?It should be noted that the price elasticity of demand simply means the ratio of the percentage change in quantity demanded to the percentage change in price.
In this case, the function is given as:
q = D(p) = 600-3p
Differentiate with respect to p
D'(p) = 3
The elasticity of demand will be:
= (P / 600 - 3p) × (-3)
= P / (200 - P)
In conclusion, the correct option is C.

If you spend 1 hours a week studying for English and 3.5 hours studying for math what is the ratio of time spent studying in math to studying for English?
The ratio of time spent studying math to studying English is 7:2.
According to the question,
We have the following information:
One spends 1 hour a week to study English and 3.5 hours to study math.
Now, we know that the ratio can be simply understood as the division.
So, we will divide the number of hours devoted to math by the number of hours devoted to English.
Ratio of time spent studying math to studying English = 3.5/1
Ratio of time spent studying math to studying English = 35/10
(Now, we will convert this fraction into the simplest form by dividing both the numerator and denominator of the fraction by 5.)
Ratio of time spent studying math to studying English = 7/2
Ratio of time spent studying math to studying English = 7:2

The number of hours it takes for ice to melt varies inversely with the air temperature. A block of ice melts in 2.5 hours whenthe temperature is 54 degrees.How long would it take for the same block of ice to melt if the temperature was 45 degrees?

vera wants to prove that any rectangle is also a parallelogram
We are given a rectangle ABCD
Recall that a rectangle is a quadrilateral in which all angles are right angles (90°)
Each pair of interior angles are supplementary. The two right angles add to a straight angle which means that the opposite sides of a rectangle are parallel.
In quadrilateral ABCD, if m∠A = m∠B = m∠C = m∠D = 90° then AB || DC and AD || BC
Hence, a rectangle is also a parallelogram.

Here, we want to check the correct statement
Basically from the diagram, it is confirmed that what we have is a 30-60-90 triangle
Now, for a 30-60-90 degrees triangle, the side lengths are in a particular ratio
From the diagram, MO faces the right angle and thus, it is the longest side and the hypotenuse
Now, let us take a look at the ratio of the sides in both submissions
For a 30-60-90 degrees triangle, the ratio of the sides is;

From Kellie's statement we can see MO is twice NO
From Eddie's statement, we can also see that MO is twice NO
Lastly, we can also see in both that dividing MN by NO yields the root of 3 in both statemets which confirms the existence of the theoretical ratio
