Answer:
([tex]\frac{1}{2}[/tex], [tex]\frac{-1}{2}[/tex])
Step-by-step explanation:
Use the midpoint formula to solve.
1) Given 2 points: ([tex]x_{1}[/tex], [tex]y_1[/tex]) and ([tex]x_2[/tex], [tex]y_2[/tex])
The midpoint formula would be ([tex]\frac{x_1+x_2}{2}[/tex], [tex]\frac{y_1+y_2}{2}[/tex]).
2) Based on this, we can easily find the midpoint of AB.
-3 would be [tex]x_1\\[/tex] -5 would be [tex]y_1[/tex] 4 would be [tex]x_2[/tex] the next 4 would be [tex]y_2[/tex]3) With this information, we can solve for the midpoint.
([tex]\frac{-3+4}{2}[/tex], [tex]\frac{-5+4}{2}[/tex]) --> ([tex]\frac{1}{2}[/tex], [tex]\frac{-1}{2}[/tex]) --> This is your answer.
I need to find the equation of the graphed line.
Answer:
y=-x-7
Step-by-step explanation:
So the line goes down one unit for every unit it goes to the left.
Slope is rise over run which would be -1/1 (simplify to -1)
The line crosses the y axis at -7
So to put it in slope-intercept form (y=mx+b) it would be y=-1x-7
You don't have to include the one in -1x because its the same as saying -x
Answer: 20-w33

Answer:
Period = pi
Angular frequency = 2
Amplitude = 5
Midline is the line y = 3
Step-by-step explanation:
A sinusoidal wave is written in the general form as:
f(x) = A*cos(w*x) + C
Where:
- A is the amplitude.
- w is the angular frequency, this is equal to 2*pi/T
where T is the period.
- y = C is the midline.
Then in the equation:
f(x) = 5*cos(2*x) + 3
- 5 is the amplitude.
- 2 is the angular frequency (in the image is called frequency, but this quantity must be in radians/time, while the normal frequency is only in Hz)
- We know that the angular frequency is equal to 2*pi/T, whit this eqation we can find the period:
2 = 2*pi/T
T = 2*pi/2 = pi
pi is the period.
- y = 3 is the midline.

, 9
Then DO
Answer:
The length of segment [tex]\overline{DO}[/tex] is [tex]\displaystyle \frac{24}{5}[/tex].
Step-by-step explanation:
Start by verifying that [tex]\triangle DAB \sim \triangle MEB[/tex], and that [tex]\triangle DOA \sim \triangle BOC[/tex].
Both [tex]\triangle DAB[/tex] and [tex]\triangle MEB[/tex] contain the angle [tex]\angle DBA[/tex]. Hence, another pair of equal angles will be sufficient to prove [tex]\triangle DAB \sim \triangle MEB[/tex] by the angle-angle similarity postulate.
Notice that because [tex]\overline{AD} \; \| \; \overline{EF}[/tex], the corresponding angles next to those two lines would be equal: [tex]\angle MEB = \angle DAB[/tex]. Both [tex]\angle MEB[/tex] is in [tex]\rm \triangle MEB[/tex] whereas [tex]\angle DAB[/tex] is in [tex]\triangle DAB[/tex].
Hence, [tex]\triangle DAB \sim \triangle MEB[/tex] by the angle-angle similarity postulate.
Notice how [tex]\angle DOA[/tex] in [tex]\triangle DOA[/tex] and [tex]\angle BOC[/tex] in [tex]\triangle BOC[/tex] are two vertically opposite angles (and are thus equal to one another.) That is: [tex]\angle DOA = \angle BOC[/tex].
Because [tex]\overline{AD} \| \overline{BC}[/tex], the alternate interior angles [tex]\angle DAO[/tex] and [tex]\angle BCO[/tex] are also equal to one another. That is: [tex]\angle DAO = \angle BCO[/tex]
Hence, [tex]\triangle DOA \sim \triangle BOC[/tex], also by the angle-angle similarity postulate.
Notice that [tex]\triangle DAB \sim \triangle MEB[/tex] implies that:[tex]\begin{aligned} & \frac{\left| \overline{BM} \right|}{\left| \overline{BD} \right|} \\ &= \frac{\left|\overline{EB}\right|}{\left|\overline{AB}\right|} && (\triangle MEB \sim \triangle DAB) \\ &= \frac{\left|\overline{EB}\right|}{\left|\overline{AE}\right| + \left|\overline{EB}\right|} \\ &= \frac{\left|\overline{EB}\right|}{2\, \left|\overline{EB}\right| + \left|\overline{EB}\right|} && (\text{given that $\left|\overline{AB}\right| = 2\,\left|\overline{EB}\right|$})\\ &= \frac{1}{3}\end{aligned}[/tex].
Therefore:
[tex]\begin{aligned}&\left|\overline{BD}\right|\\ &= 3\, \left|\overline{BM}\right| \\ &= 12\end{aligned}[/tex].
Similarly, [tex]\triangle DOA \sim \triangle BOC[/tex] implies that:
[tex]\begin{aligned} \frac{\left| \overline{DO} \right|}{\left| \overline{BO} \right|} &= \frac{\left|\overline{AD}\right|}{\left|\overline{BC}\right|} && (\triangle DOA \sim \triangle BOC) \\ &= \frac{6}{9} = \frac{2}{3}\end{aligned}[/tex].
Therefore, [tex]\displaystyle \left|\overline{BO}\right|= \frac{3}{2}\, \left|\overline{DO}\right|[/tex].
[tex]\begin{aligned} \frac{\left| \overline{DO} \right|}{\left| \overline{BD} \right|} &= \frac{\left| \overline{DO} \right|}{\left| \overline{BO} \right| + \left| \overline{DO} \right|} \\ &= \frac{\left| \overline{DO} \right|}{(3/2)\, \left| \overline{DO} \right| + \left| \overline{DO} \right|} = \frac{2}{5}\end{aligned}[/tex].
It was already found that [tex]\left|\overline{BD}\right| = 12[/tex]. Therefore:
[tex]\displaystyle \left|\overline{DO}\right| = \frac{2}{5}\, \left|\overline{BD}\right| = \frac{24}{5} = 4.8[/tex].
Your car needs new brakes. You call a dealership and a local mechanic for prices. Cost of parts Labor cost per hour Dealership $24 $99 Local mechanic $45 $89 a. After how many hours are the total costs the same at both places
Answer:
The indifference point is 2.1 hours.
Step-by-step explanation:
First, we need to calculate the total cost for each option:
Dealership:
Total cost= 24 + 99x
Local mechanic:
Total cost= 45 + 89x
x= number of hours
Now, we need to equal both formulas and isolate x:
24 + 99x = 45 + 89x
10x = 21
x= 2.1
The indifference point is 2.1 hours.
Prove:
Total cost= 24 + 99*2.1= $231.9
Total cost= 45 + 89*2.1= $231.9
Joey is 13 years and 5 months old. His friend Suzy is 4,860 days old.
Who is older?
How many months old is the older person?
Answer:
The Joey is older as he is 13 years and 5 months old
Also the difference is of 2 months 8 days approx
Step-by-step explanation:
The computation is shown below:
Given that
Joey is 13 years and 5 months old
And his friend Suzy is 4,860 days old i.e. 13 years and 3 months old + 22 days
So as we can see that
The Joey is older as he is 13 years and 5 months old
Also the difference is of 2 months 8 days approx
So the same is to be considered and relevant

I hope it helps ❤❤A swimming pool containing 2000l of water is 1/16 full. How many litres of water is required to make the pool half full
Answer: 16,000 litres
Step-by-step explanation:
1/16 of the pool is 2000l
8/16 full is 1/2 of the pool full
1/16 = 2000
8/16 = x
Cross multiply
1/16x = 2000 × 8/16
1/16x = 1000
Multiply both sides by 16
x = 16000
To make the pool half full, 16,000 litres is required.
16000 liters of water is required to make the pool half full.
What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Suppose we have two ratio p : q and r : s.
If both these ratios are proportional, then we can write it as p: q : : r : s.
This is same as p : q = r : s or p/q = r/s
Given that,
A swimming pool containing 2000l of water is 1/16 full.
We have to calculate the amount of water required to make the pool half full.
Let x be the liter of water required to make the pool half full.
Using proportional concept,
2000 : 1/16 = x : 1/2
This can be written as,
2000 / (1/16) = x / (1/2)
2000 × 16 = 2 x
x = (2000 × 16) / 2
x = 16000
Hence it would require 16000 liters of water to make half full pool.

A triangular prism, with bases consisting of equilateral triangles of side length s, has height h and a volume of 250. If the surface area of the prism includes the areas of all the sides and the bases, what value of s minimizes the surface area of the prism
Answer:
10
Step-by-step explanation:
The required value of s to minimize the surface area of the prism is given as 10.
What is a triangular prism?A triangular prism has 2 triangles as their top and bottom and three other faces as rectangles. The volume of the prism is given as the product of its height and base area.
The given problem can be solved as follows,
The expression for the volume of the prism is given as,
V = √3/4 × s²h
Substitute V = 250 to obtain,
250 = √3/4 × s²h
⇒ s²h = 1000/√3 (1)
And, the expression for the surface area is given by,
A = 3 × sh + √3/4s²
Substitute h = 1000/(√3s²) in the above equation to obtain,
A = 1000√3/s + √3/4s²
In order to get the minimum area differentiate A with respect to s and equate it to zero to get,
dA/ds = 0
⇒ √3/2s - 500√3/s² = 0
⇒ s = 10
Hence, in order to minimize the area the the value of s is obtained as 10.
