If T is the circumcenter of triangle MNP, find each measure.
Answers
Answer:
8). TN = 22 units ; 9). √165
Step-by-step explanation:
The circumcenter of a triangle is the point in the plane equidistant from the three vertices of the triangle.
8). 6x - 56 = 3x - 17
3x = 39
x = 13
TN = 22 units
9). 4x - 17 = x + 10
3x = 27
x = 9
TN = 19
RT = [tex]\sqrt{TN^2 - RN^2}[/tex]
RT = [tex]\sqrt{361-196}[/tex] = √165 ≈ 12.8 units
Applying the properties of circumcenter of a triangle and the Pythagorean Theorem, the measure of each given segments are calculated as:
8. TN = 22
9. RT = 12.8
Recall:
The point where the three perpendicular bisectors of a triangle meet is known as the circumcenter of the triangle.The perpendicular bisectors form right angles with each side it bisects. This means that there are two opposite right angles formed at point Q, S, and R.The circumcenter is also the point that is equidistant to all three vertices of the triangle. This means that, in the diagram given, MT, TN, and TP are equal.Pythagorean theorem can be used to solve for the missing side of a right triangle. It states that, if c is the hypotenuse (longest side that is directly opposite to the right triangle), and a and b are the two other smaller sides, therefore: [tex]c^2 = a^2 + b^2[/tex]8. Find TN
Given,
MT = 6x - 56TP = 3x - 17Thus,
6x - 56 = 3x - 17 (MT = TN = TP, because they are equidistant from the circumcenter, T.)
Combine like terms6x - 3x = 56 - 17
3x = 39
Divide both sides by 3x = 13
TN = TP = 3x - 17
TN = 3x - 17
Plug in the value of xTN = 3(13) - 17
TN = 22
9. Find RT
Given,
RN = 14TN = 4x - 17TP = x + 10Thus,
4x - 17 = x + 10 (TN = TP)
Combine like terms4x - x = 17 + 10
3x = 27
Divide both sides by 3x = 9
TN = 4x - 17
Plug in the value of xTN = 4(9) - 17
TN = 19
To find RT, apply the Pythagorean Theorem
[tex]RT = \sqrt{TN^2 - RN^2}[/tex]
Substitute[tex]RT = \sqrt{19^2 - 14^2}\\\\\mathbf{RT = 12.8}[/tex]
In summary, applying the properties of circumcenter of a triangle and the Pythagorean Theorem, the measure of each given segments are calculated as:
8. TN = 22
9. RT = 12.8

Answers
Answer:
Verduras= $100
Lacteos= $60
Menestras= $120
Frutas y verduras= $80
Limpieza= $40
Step-by-step explanation:
Presupuesto= $400
Primero determinamos la proporción a gastar en cada rubro:
Verduras= 0.25
Lacteos= 0.15
Menestras= 0.3
Frutas y verduras= 0.2
Total= 0.9
Limpieza= (1 - 0.9) = 0.1
Ahora, la cantidad de dinero:
Verduras= 0.25*400= $100
Lacteos= 0.15*400= $60
Menestras= 0.3*400= $120
Frutas y verduras= 0.2*400= $80

expand quadratic equation (2x-3)(x+4) = 0
Answers
Answer:
Step-by-step explanation:
Simplifying
(2x + -3)(x + -4) = 0
Reorder the terms:
(-3 + 2x)(x + -4) = 0
Reorder the terms:
(-3 + 2x)(-4 + x) = 0
Multiply (-3 + 2x) * (-4 + x)
(-3(-4 + x) + 2x * (-4 + x)) = 0
((-4 * -3 + x * -3) + 2x * (-4 + x)) = 0
((12 + -3x) + 2x * (-4 + x)) = 0
(12 + -3x + (-4 * 2x + x * 2x)) = 0
(12 + -3x + (-8x + 2x2)) = 0
Combine like terms: -3x + -8x = -11x
(12 + -11x + 2x2) = 0
Solving
12 + -11x + 2x2 = 0

Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + -2x = 0 + -3
Combine like terms: 3 + -3 = 0
0 + -2x = 0 + -3
-2x = 0 + -3
Combine like terms: 0 + -3 = -3
-2x = -3
Divide each side by '-2'.

Add '-4' to each side of the equation.
4 + -4 + -1x = 0 + -4
Combine like terms: 4 + -4 = 0
0 + -1x = 0 + -4

5. An airplane takes 4 hr to travel a distance of 4100 km. Another airplane travels at a speed
which is 200 km/hr less than first airplane. How long will it take to travel the same distance by
the second airplane?
Answers
Answer:
4.969696 hours
Step-by-step explanation:
The distance traveled is shown through the following equations
Distance = velocity * time
This means that
4100=velocity*4
This means that ariplane 1 travles at 1025 km/hr
We can then subtract 200 from this to find that airplane two travels at a speed of 825 km/hr
Now we need to find how long it takes for that plane to travel 4100
So using the same equation
4100=825*time
Divison will tell us that the answer is around 4.9696 hours which is pretty much 5
A triangle has side lengths of n, n – 3, and 2(n − 2). If the perimeter of the triangle is at least 37 units, what is the value of n?
OA.
n> 11
OB
n> 8
O C.
n > 10.5
OD
n > 7.5
Answers
Answer:
n = 11
Step-by-step explanation:
The side length of a triangle are n,n-3 and 2(n-2).
The perimeter of the triangle, P = 37 units
We need to find the value of n.
Perimeter = sum of all sides
n+n-3 +2(n-2) = 37
2n-3+2n-4 = 37
4n -7 = 37
4n = 37+7
4n = 44
n = 11
So, the value of n is 11.
Madelyn has already cycled 4 kilometers this year, plus she plans to cycle 2 kilometers during each trip to work. Write an equation that shows the relationship between the number of trips to work x and the total distance cycled y.
Answers
Answer: y = 4km + 2km*x
Step-by-step explanation:
We know that Madelyn already cycled 4km this year, so we start at that point.
Now, each time that she goes to work, she cycles 2 km in total.
Now, if she does x trips to work, then she cycles 2km x times, this means that in total she would cycle 2km*x
if we also count the 4km she already has, we have the linear equation:
y = 4km + 2km*x
This is the equation we wanted to get.

If x= -4 and y= -3 what does 3x - 2y equal
Answers
Answer:
-6
Step-by-step explanation:
3(-4) = -12
-2(-3)= 6
-12+6= -6
Answer:
-6
Step-by-step explanation:
If x = -4 and y = -3, the equation should be set up like this: 3(-4) - 2(-3). The rule is if you multiply a 1 positive number by 1 negative number, the answer will be negative.
3(-4) = -12
2(-3) = -6
Then, once you figure out the multiplication, finish up the equation by subtracting.
-12 - (-6) = -6

The value y of an investment x months after the money was invested is given according to the equation below. y = 25,000(1.16)-x As time goes on, does the value of the investment grow or decay?
Answers
Answer:
Decay
Step-by-step explanation:
The value, y of an investment x is given by:
y = 25000(1.16)^-x
x = number of month after investment
y = value of investment after x months
The function f(y) above is an exponential usually related in the form:
y = Ar^-x
Plugging values of x into the function :
After 1 month; x = 1
y = 25000(1.16)^-1 = 21551.724
After 2 month; x = 2
y = 25000(1.16)^-2 = 18579.072
After 3 month; x = 3
y = 25000(1.16)^-3 = 16016.441
Since y is decreasing with increasing value of x, then we have a decay
Answer:
Decay
