Answer:
∠ 3 = 110°
Step-by-step explanation:
The measure of the tangent- chord angle is half the the measure of its intercepted arc.
intercepted arc = 360° - 140° = 220°
∠ 3 = 0.5 × 220° = 110°
The measure of angle 3 is 110 degree.
What is Tangent?A line that touches a circle or an ellipse at just one point is said to be tangent in geometry. Assuming a line contacts the curve at P, "P" is referred to be the point of tangency. In other words, it is described as the line that, at that particular location, indicates the slope of a curve.
We have,
Arc= 140
As, The tangent-chord angle's measurement is equal to half of its intercepted arc's measurement.
So, the intercepted arc
= 360° - 140°
= 220°
Now, <3 = 1/2 × 220° = 110°
Thus, the measure of angle 3 is 110 degree.

5. Miguel has an after-school job. He works
between 15 and 25 hours each week and is paid
$12 per hour. What is an appropriate domain for
this scenario?
A. All real numbers such that 15
B. All real numbers such that 180 < x < 300
C. All real numbers
D. All real numbers such that x>0
Answer:
The domain is 15 ≤ x ≤ 25
Step-by-step explanation:
The given parameters are;
The number of hours Miguel works each week = Between 15 and 25 hours
The amount he is paid per hour = $12
Therefore, we have;
The domain is all real numbers, 'x', such that 15 ≤ x ≤ 25
The amount Miguel makes each week, 'y' is between; 12 × 15 ≤ A ≤ 12 × 25
Therefore the range is 180 ≤ y ≤ 300.

Find the value of x.
Answer:
x = 3
Step-by-step explanation:
Given 2 intersecting chords, then
The product of the parts of one chord is equal to the product of the parts of the other chord, that is
5x × x = 5 × 9
5x² = 45 ( divide both sides by 5 )
x² = 9 ( take the square root of both sides )
x = [tex]\sqrt{9}[/tex] = 3

Answer:
The measure of arc AC length is 90 degrees
Step-by-step explanation:
Here, we want to get the measure of the arc AC
From what we have, the angle at the middle facing this arc is a right angle
A right angle is of the size 90. degrees
with respect to the diagram, the angle at the center is equal to the measure of the arc facing it
Thus, we can conclude here in this case that the measure of arc AC is 90 degrees

what is the area in square inches of the trapezoid below.
Answer:
50 in²
Step-by-step explanation:
What is the area in square inches of the trapezoid below.
Area of a trapezoid = 1/2(b1 + b2) h
Where
b1 = First base = 8in
b2 = Second base = 12in
h = Height = 5in
Area of trapezoid = 1/2(8 + 12) × 5
= 1/2 × 20 × 5
= 50 in²
The area of the trapezoid is 50 square inches

Step-by-step explanation:
Consider the coordinates of A and A'
A (0, 0 ) and A' (5, 2 )
This represents a move of + 5 (0 → 5) units in the x- direction and a move of + 2 ( 0 → 2 ) units in the y- direction.
The figure is unchanged and must therefore be a translation with rule

2x - 8y = 6
-2x + 2y = 7
Add the two equations together by combining like terms:
2x + -2x = 0
-8y + 2y = -6y
and 6 + 7 = 13
So when you combine the terms you end up having:
-6y = 13
Now solve for y by dividing each side by -6:
y = 13/-6
Rewrite by moving the negative sign in front of the fraction to get
y = -13/6
The answer is C.
Solve for y in the two equations below using substitution.
2x - 8y = 6 -2x + 2y = 7____________________Solution :-Given Information :-Equation 1 ➢ 2x - 8y = 6 Equation 2 ➢ -2x + 2y = 7 To Find :-Solve for y in the two equations.Calculation :-Equation 1 ➢ 2x - 8y = 6
Equation 2 ➢ -2x + 2y = 7
Adding both equations together, by combining similar terms, We get,
2x + -2x = 0-8y + 2y = -6y6 + 7 = 13When we combine the terms, We get,
⇒ -6y = 13
Now, solving for y, by divide Right Hand Side & Left Hand Side by -6, We get,
⇒ y = [tex] \sf \frac{13}{-6} [/tex]
⇒ y = [tex] \sf \frac{-13}{6} [/tex]
∴ The value of y is [tex] \bf \frac{-13}{6} [/tex]

[tex]f(8)=0[/tex]
To find:
The all of the zeros of f(x) algebraically.
Solution:
We have, [tex]f(8)=0[/tex] is means 8 is a zero of given function and (x-8) is a factor of given function.
The function is:
[tex]f(x)=x^3-4x^2-37x+40[/tex]
Spittle the middle terms in such a way so that we get (x-8) as a common factor.
[tex]f(x)=x^3-8x^2+4x^2-32x-5x+40[/tex]
[tex]f(x)=x^2(x-8)+4x(x-8)-5(x-8)[/tex]
[tex]f(x)=(x^2+4x-5)(x-8)[/tex]
Spittle the middle term of the quadratic expression, we get
[tex]f(x)=(x^2+5x-x-5)(x-8)[/tex]
[tex]f(x)=(x(x+5)-1(x+5))(x-8)[/tex]
[tex]f(x)=(x+5)(x-1)(x-8)[/tex]
For zeros, [tex]f(x)=0[/tex].
[tex](x+5)(x-1)(x-8)=0[/tex]
[tex](x+5)=0\text{ and }(x-1)=0\text{ and }(x-8)=0[/tex]
[tex]x=-5\text{ and }x=1\text{ and }x=8[/tex]
Therefore, the all zeros of the given function are -5, 1 and 8.

Answer:
y = 5x -2
Step-by-step explanation:
The slope is given by the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (8 -3)/(2 -1) = 5
The y-intercept is given by the formula:
b = y -mx
b = 3 -5(1) = -2
Then the slope-intercept form equation is ...
y = mx +b
y = 5x -2 . . . . . . . . using the m and b we found above

are white and the other 2 pairs are red. If
Jeff grabs for one pair quickly and without
looking, what's the probability that he will grab
a red pair of socks? Write your answer as a
percent.
Answer: 40% chance
Sample space: 3 white 2 red, 5 pairs
2/5 probability, as a percent would be 40% chance
The probability that Jeff will grab a red pair of socks is 0.4.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Three pairs are white and the other 2 pairs are red. Therefore, the probability that Jeff will grab a red pair of socks is,
Probability = 2/5 = 0.4
Hence, the probability that Jeff will grab a red pair of socks is 0.4.

.Un recipiente cilíndrico de 5cm de radio y 10cm de altura se llena de agua. Si la masa del recipiente lleno es de 2kg, ¿cuál es la masa del recipiente vacío?
Answer:
La masa del recipiente vacío es 1,2146 kg.
Step-by-step explanation:
La densidad se define como la propiedad que tiene la materia, ya sean sólidos, líquidos o gases, para comprimirse en un espacio determinado. En otras palabras, la densidad es una magnitud que permite medir la cantidad de masa que hay en determinado volumen de una sustancia. Entonces, la expresión para el cálculo de la densidad es el cociente entre la masa de un cuerpo y el volumen que ocupa:
[tex]densidad= \frac{masa}{volumen}[/tex]
Entonces la masa puede ser expresada como:
masa= densidad*volumen
En este caso:
densidad del agua= 1000 [tex]\frac{kg}{m^{3} }[/tex]volumen del recipiente cilíndrico= π*radio²*altura= π*(5 cm)²* 10 cm= π*(0,05 m)²*0,1 m= 7,854*10⁻⁴ m³Reemplazando:
masa= 1000 [tex]\frac{kg}{m^{3} }[/tex] * 7,854*10⁻⁴ m³
masa=0.7854 kg
Si la masa del recipiente lleno es de 2 kg, entonces se le resta la masa de agua calculada:
2 kg - 0,7854 kg= 1,2146 kg
Entonces, la masa del recipiente vacío es 1,2146 kg.
