12. A circle has a center at C(2,5) and a point on the circle has coordinates A(8, 13). Could the point B lie on
the same circle if lies at B(9.1)? Justify.
Answer:
No.
Step-by-step explanation:
A circle is defined as a figure in which all points are equidistant from the center, or C. In order to determine how far points A and B are from the center, we must first find the difference in positioning from (2,5) to each point and then use Pythagorean Theorem to calculate the length of the hypotenuse. Point A establishes that the radius of the circle must be 10 units, and Point Bis only about 8 units away.

Step-by-step explanation:
1. Find the area of the shaded sector.
2. Find the length of the arc defined by the sector.
Answer:
1. 150π sq.ft 2. 10π ft
Step-by-step explanation:
Part 1Equation: Area of a sector = [tex]\frac{x}{360}[/tex] × π[tex]r^{2}[/tex]
Where:
x = internal angle
r = radius of circle
Values from problem:
x = 60
r = 30
Plug values into equation:
Area of sector = [tex]\frac{60}{360}[/tex] × π[tex]30^{2}[/tex]
Simplify:
60 divided by 30 equals [tex]\frac{1}{6}[/tex] and 30 squared equals 900 so...
[tex]\frac{1}{6}[/tex] × 900π
900π divided by 6 equals 150π so...
[tex]\frac{900}{6}[/tex] × π = 150π
150π sq. ft
Part 2Equation: Arc length = [tex]\frac{x}{360}[/tex] × 2πr
Where:
x = internal angle
r = radius of circle
Values from Problem:
x = 60
r = 30
Plug values into equation:
Arc length = [tex]\frac{60}{360}[/tex] × 2π30
Simplify:
60 divided by 360 equals [tex]\frac{1}{6}[/tex], and 2π × 30 equals 60π so...
[tex]\frac{1}{6}[/tex] × 60π
60π divided by 6 is 10π
[tex]\frac{60}{6}[/tex]π = 10π
10π ft

Information is given about a polynomial f(x) whose coefficient are real numbers. Find the remaining zeros of f.
Degree 3; zeros: -2,4-i
Please help!
Answer:
Remaining zeros x= 4+i
Step-by-step explanation:
since complex roots always occur in conjugate pairs.
so if one root is 4-i the other one will be 4+i
Suppose y varies directly with x, and y=98 when x=14. Write the direct
variation equation that relates x and y.
===========================================================
Explanation:
Since y varies directly with x, this means y = kx for some constant k.
Plug in y = 98 and x = 14 to solve for k
y = kx
98 = k*14
98/14 = k
7 = k
k = 7
Therefore, y = kx updates to y = 7x which is the equation we're after.
Answer:
y = 7x
Step-by-step explanation:
The general formula for direct variation is y = kx, where k is the constant of proportionality. If y = 98 when x = 14, then k must be 98/14. or 7, and so
y = 7x is the desired direct variation equation.
how do I find the domian in exponential function
Answer:
For any exponential function, f(x) = abx, the domain is the set of all real numbers. For any exponential function, f(x) = abx, the range is the set of real numbers above or below the horizontal asymptote, y = d, but does not include d, the value of the asymptote.

19% of 288 i need help
Answer:
54.72
Step-by-step explanation:
multiply 19% by 0.01multiply 0.19 by 28819·0.01=0.19
0.19·288=54.72
Therefore, 19% of 288 will be 54.72.
Answer:
54.72
Step-by-step explanation:
% = per cent or per 100 so 19% can be written as 0.19
288 * 0.19 would get you 54.72

A student is conducting a probability experiment and wants to know the total number of outcomes for the experiment. The student's experiment is comprised of three events
• rolling a six-sided number cube • •flipping a coin
• rolling a six-sided number cube again
How many outcomes are possible in this experiment?
A. 14
B. 24
C. 72
D. 38
Answer:So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. So to get two 6s when rolling two dice, probability = 1/6 × 1/6 = 1/36 = 1 ÷ 36 = 0.0278, or 2.78 percent.
Step-by-step explanation:
Answer:
C.72
Step-by-step explanation:
rolling a six-sided number cube(6) x flipping a coin(2) x rolling a six-sided number cube again(6)= 72
6x6= 36
36 x 2 = 72
6x2=12
12 x 6 = 72

A spinner is divided into sections of equal size, some of which are red, some are blue, and the remaining are green. The probability of the arrow landing on a red section is 40%. The probability of the arrow landing on a blue section is 25%.
What is the probability of the arrow landing on a green section?
Group of answer choices
35%
65%
25%
50%
Answer:
35%
Step-by-step explanation:
X=the probability of the arrow landing on a green section.
Equation:
40+25+ x = 100
65 +x = 100
(65-65) + x = 100-65
X= 35

Answer:
Step-by-step explanation:
Slope of line passing through (x₁, y₁) and (x₂, y₂) = (y₂-y₁)/(x₂-x₁)
Slope of line passing through (9, 7) and (2, 9) = (9-7)/(2-9) = -2/7
Answer:
The slope is [tex] - \frac{2}{7} [/tex]

Step-by-step explanation:
☆Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

☆We need to find the slope . So just plug in according to the slope formula!
[tex]m = \frac{9 - 7}{2- 9} = \frac{ \: \: 2}{ - 7} = - \frac{2}{7} [/tex]
