If T is the circumcenter of triangle MNP, find each measure.
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

Su restaurante: "Hola hijo, este sábado tenemos que hacer las compras de la semana. Nuestro presupuesto es S/ 400 y acordamos distribuirlos así con tu mamá: 25 % en verduras, 15 % en lácteos, 30 % en menestras, 20 % en frutas y el resto en artículos de limpieza. ¿Podrías ayudarnos diciéndonos cuánto dinero utilizaremos para cada cosa? 1
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
Limpieza= 0.1*400= $40

~AH1807Linnett is planning a concert and needs to tell the bands that are playing how big the stage is. The stage has a width of 32 ft. And a depth of 17 ft. What is the area of the triangular stage below, in square feet?
Answer:
272 ft²
Step-by-step explanation:
Given that:
Width = 32 = length of base ; depth = 17 = height
Area of triangle :
A = 0.5 * base * height
A = 0.5 * 17 * 32
A = 272 ft²
Area of triangular stage = 272 ft²

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.
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
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

expand quadratic equation (2x-3)(x+4) = 0
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

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

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?
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

write an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4
Answer:
We conclude that an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4 will be:
[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]
Step-by-step explanation:
Given the line
y+2x=4
converting into the slope-intercept form y = mx+b where m is the slope
y = -2x+4
comparing with the slope-intercept form
Thus, the slope is: m = -2
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = -2
The slope of the new line perpendicular to the given line = – 1/m
= -1/-2 = 1/2
Using the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 1/2 and the point (-3, 5)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-5=\frac{1}{2}\left(x-\left(-3\right)\right)[/tex]
[tex]y-5=\frac{1}{2}\left(x+3\right)[/tex]
Add 5 to both sides
[tex]y-5+5=\frac{1}{2}\left(x+3\right)+5[/tex]
[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]
Therefore, we conclude that an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4 will be:
[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]
