Answer:
The correct answer is C- (X-5)Solution
Given -
polynomial p(x) = x³ - 23x² + 142x - 120
Now see the coefficients
coefficient of x³ is 1 x² is -23 x is 142 and then -120
when you'll add this coefficients
i.e.
1-23+142-120=0
When sum of the coefficient turn out 0 then x = 1
using x=1, x-1 = 0
devide the given polynomial p(x) = x³ - 23x² + 142x - 120 by x-1 you'll get rest two factors hence

Alejandro compra un terreno de 0,3 hm cuadrados y 0,9 dam al cuadrados ¿cuanto ha pagado por el terreno
Answer:
Si el metro cuadrado es a $ 50 Alejadro pagó por el terreno $195 000
Step-by-step explanation:
Ya que no se especifica un valor por unidad de área podemos suponer por ejemplo $ 50 / metro^2
Terreno:
0.3 hm^2
0.9 dam^2
1) Vamos convertir a la misma unidad de área las áreas del terreno para poder saber su costo.
-Hectómetro cuadrado
1 hm^2 = 10 000 m^2
Por lo tanto,
0.3 hm^2 * 10 000 m^2 / 1 hm^2 = 3000 m^2
-Decámetro cuadrado
1 dam^2 = 1 000 m^2
Por lo tanto,
0.9 dam^2 * 1 000 m^2 /1 dam^2 = 900 m^2
Así que el total del terreno es de 3900 m^2
2) Ahora podemos calcular el valor total del terreno
area* valor (por m^2)
3900 m^2 * $50/ m^2 = $195 000

In the figure below mPUR =77 and mST=74 Find mPR
Answer:
a)
The angle formed by intersecting chords is half of the sum of the intercepted arcs:
1/2(mST + mPR) = m∠PUR1.2(74° + mPR) = 77°74° + mPR = 2*77°mPR = 154° - 74°mPR = 80°b)
The angle formed by two tangents is the half of the difference of the intercepted arcs:
m∠PSR = 1/2(mPTR - mPR)m∠PSR = 1/2(247° - (360° - 247°))m∠PSR = 247° - 180°m∠PSR = 67°Find the areas of a circle whose diameter is 21 cm
Answer:
Your answer is 346.36059
Step-by-step explanation:
A = pi*r²
A = pi * 10.5²
A = pi * 110.25
A = 346.36059
We can write the the area of the circle as 110.25π square centimeter.
What is Area?Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -
V = ∫∫F(x, y) dx dy
Given is a circle whose diameter is 21 cm.
It is asked to find the area of a circle whose diameter is 21 cm.
It is given that the diameter of the circle is -
d = 21 cm
r = d/2 = 21/2
r = 10.5 cm
We know that the area of the circle as -
Area = πr²
Area = π x 10.5 x 10.5
Area = 110.25π
So, it can be concluded that the area of the circle is 110.25π square centimeter.
Therefore, we can write the the area of the circle as 110.25π square centimeter.

Answer:
3a. yes
3b. y= 75x
3c. 600 mi
3d. 10 inches
Step-by-step explanation:
3a: if you divide the y by the x, you'd get 75 everytime, meaning it's proportional.
3b: y would equal the amount of inches multiplied by 75, so y=75x
3c: you can use the equation and substitute the x for 8, so y=75(8), giving you 600 miles
3d: you can also use the equation in reverse, if the actual miles is 750, then this is your y, so it would look like 750=75x and to solve you'd divide, 750/75, giving you 10 inches

Find the distance between P and Q
9514 1404 393
Answer:
10
Step-by-step explanation:
The distance formula is useful.
d = √((x2 -x1)^2 +(y2 -y1)^2)
d = √((7 -1)^2 +(12 -4)^2) = √(6^2 +8^2) = √(36 +64) = √100
d = 10
The distance between P and Q is 10.

solve for y. -5(6+7y)= -5(6+y)
Answer:
y = 0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−5(6+7y)=−5(6+y)
(−5) (6) + (−5) (7y) = (−5) (6) + (−5) (y) (Distribute)
−30 + − 35y = −30 + −5y
−35y − 30 = −5y −30
Step 2: Add 5y to both sides.
−35y − 30 + 5y = −5y −30 + 5y
−30y −30 = −30
Step 3: Add 30 to both sides.
−30y − 30 + 30 = −30 + 30
−30y = 0
Step 4: Divide both sides by -30.
−30y /−30 = 0 /−30
A radio station signal covers a circular area out from the signal tower. It gets weaker the farther away your are. The local station WDHS (at location (0,0)) sends it signal out with a coverage radius of 5 miles. 1) Will we hear it better at Zaxby's (2,-4), McDonalds (4, -4), or Dunkin' (-3,3). Show work to support your decision and explain your reasoning. 2) Are any of these location outside the range of the radio station? If so, which one(s). Defend your decision mathematically.
Answer:
1. We would hear better at Dunkin's since its distance from the radio station is the shortest.
2. McDonald's is out of range of the radio station since its distance is greater than the range of the radio station.
Step-by-step explanation:
1) Will we hear it better at Zaxby's (2,-4), McDonalds (4, -4), or Dunkin' (-3,3). Show work to support your decision and explain your reasoning.
We need to find the distance of each point from the tower.
The shorter the distance from the radio station the better the signal.
The distance between two points (x₁, y₁) and (x₂, y₂) is given by d = √[(x₂ - x₁)² + (y₂ - y₁)²].
With (x₁, y₁) = (0, 0) the location of local station WDHS
For Zaxby's distance located at (2, -4) = (x₂, y₂)
So, d₁ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(2 - 0)² + (-4 - 0)²]
= √[(2)² + (-4)²]
= √[4 + 16]
= √20
= √(5 × 4)
= √5 × √4
= 2√5
= 4.47 miles
For McDonald's distance located at (4, -4) = (x₂, y₂)
So, d₂ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(4 - 0)² + (-4 - 0)²]
= √[(4)² + (-4)²]
= √[16 + 16]
= √32
= √(16 × 2)
= √16 × √2
= 4√2
= 5.66 miles
For Dunkin's distance located at (-3, 3) = (x₂, y₂)
So, d₃ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(-3 - 0)² + (-3 - 0)²]
= √[(-3)² + (-3)²]
= √[9 + 9]
= √18
= √(9 × 2)
= √9 × √2
= 3√2
= 4.24 miles
Since Dunkin's distance, d₃ = 4.24 is the least distance from the radio station and is within range of 5 miles, we would hear better at Dunkin's.
2) Are any of these location outside the range of the radio station? If so, which one(s). Defend your decision mathematically.
The radio station is outside of range if its distance is greater than 5 miles. That is, d > 5 miles.
So, we calculate the distance of each point from the radio station.
With (x₁, y₁) = (0, 0) the location of local station WDHS
For Zaxby's distance located at (2, -4) = (x₂, y₂)
So, d₁ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(2 - 0)² + (-4 - 0)²]
= √[(2)² + (-4)²]
= √[4 + 16]
= √20
= √(5 × 4)
= √5 × √4
= 2√5
= 4.47 miles
For McDonald's distance located at (4, -4) = (x₂, y₂)
So, d₂ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(4 - 0)² + (-4 - 0)²]
= √[(4)² + (-4)²]
= √[16 + 16]
= √32
= √(16 × 2)
= √16 × √2
= 4√2
= 5.66 miles
For Dunkin's distance located at (-3, 3) = (x₂, y₂)
So, d₃ = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(-3 - 0)² + (-3 - 0)²]
= √[(-3)² + (-3)²]
= √[9 + 9]
= √18
= √(9 × 2)
= √9 × √2
= 3√2
= 4.24 miles
So, for each of the distances calculated above, only McDonald's distance, d₂ = 5.66 miles > 5 miles.
So, McDonald's is out of range of the radio station.
If a radius of a circle is 30 inches then it’s diameter is what? Please help ty!

21. identify the secant that intersects OA.
=============================================================
Explanation:
A secant line cuts the circle so that part of the line is inside the circle, and the rest (or majority) of the line is outside the circle. In other words, the secant line intersects the circle at exactly two points.
This is in contrast to a tangent line that only touches the circle at exactly one point. Line L is the tangent line in this case.
Segment DC is a diameter of the circle as it goes through the center, and this segments endpoints are on the circle's edge. The segments AD and AC are radii of the circle.
