Using the combination formula, it is found that if the first flag is orange then the number of different signals consisting of 4 flags is 364.
The order in which the flags are chosen is not important, hence, the combination formula is used to solve this question.
What is the combination formula?[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this problem, considering that the first flag is orange, 3 flags will be chosen from a set of the remaining 14, hence the number of signals is given by:
[tex]C_{14,3} = \frac{14!}{3!11!} = 364[/tex]

What is the center and radius of the circle given by x2 + y2 - 10x - 12y + 24 = 0?
Answer:
centre (5, 6 ) , r = [tex]\sqrt{37}[/tex]
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r the radius
given
x² + y² - 10x - 12y + 24 = 0 ( collect x and y terms together and subtract 24 from both sides )
x² - 10x + y² - 12y = - 24
using the method of completing the square
add ( half the coefficient of the x / y terms)² to both sides
x² + 2(- 5)x + 25 + y² + 2(- 6)y + 36 = - 24 + 25 + 36
(x - 5)² + (y - 6)² = 37 ← in standard form
with centre (h, k ) = (5, 6 ) and r = [tex]\sqrt{37}[/tex]

What is the sequence?
A sequence is a list of objects, typically numbers, in which order matters, repetition is allowed, and the same elements can appear multiple times at different positions in the sequence.
Here given sequence is
[tex]2,7, 12,...[/tex]
Here,
[tex]a=2[/tex]
[tex]d=a_2-a_1\\d=7-2\\d=5[/tex]
The general formula of the sequence is
[tex]a_n=a+(n-1)d[/tex]
where,
[tex]a_n=[/tex] nth term
[tex]a[/tex] is the first term
[tex]d[/tex] is the common difference

pay back? (Principal and interest).
The total amount accrued, principal plus interest, from simple interest on a principal of $25,000.00 at a rate of 15% per year for 6 years is $47,500.00.
Answer:
I = $22,500.00
A = $47,500.00
Simple interestGiven Data
Principal = $25000
Rate = 15%
Time = 6 years
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 15%/100 = 0.15 per year.
Solving our equation:
A = 25000(1 + (0.15 × 6)) = 47500
A = $47,500.00

Mike is building storage boxes. Each box will have a length of 5 feet, a width of 412 feet, and a height of 312 feet. A pint of paint covers 50 square feet.
How many pints of paint does Mike need to buy in order to paint 4 boxes?
9 pints
7 pints
6 pints
5 pints
Answer:
Step-by-step explanation:
The question contains typos as I believe the boxes should be 5x4.2x3.2 in dimensions instead.
Assuming that and all 6 faces of each storage boxes will be painted, the surface area of each box is:
= (5*4.2*2) + (4.2*3.2*2) + (3.2*5*2)
= 100.88 square feet
4 boxes will have a total surface area of
100.88*4
= 403.52 square feet
Each pint of paint covers 50 square feet so a total of
403.52/50 = 8.07 or
9 pints is needed.
What is the value of x? (angle bisector problem)
Answer:

According to angle bisector theorem we get the following ratio:
VT/KT = VY/KYSubstitute the lengths and solve for x:
77/87.5 = 22/(x - 22)77(x - 22) = 87.5*2277x - 77*22 = 192577x = 1925 + 169477x = 3619x = 3619/77x = 47Use angle bisector theorem
77/87.5=22/x-2277x-1694=192577x=3619x=3619/77x=47Find x. Perimeter.

What is the perimeter of this triangle?
Step-by-step explanation:
the distance of a vertex on the 2 outgoing sides to the touching points with the inscribed circle is the same for both sides.
and that applies to all 3 vertexes.
so, we know for the top left vertex the distance to both touching points is 4.
that means the distance to the touching points from the bottom left vertex is 7-4 = 3.
and that means that the distance to the touching points from the bottom right vertex is 16-3 = 13.
so, x = 13
it is the distance to one of the touching points for the bottom right vertex.
and the perimeter of the triangle is therefore
7 + 16 + (13 + 4) = 40
What is the area and circumference of the circle? diameter = 12 cm
Answer:
Circumference = 7.68 cm
Area = 113.04 cm²
Step-by-step explanation:
First, let us find the radius of the given circle.
d = 2r
r = d / 2
r = 12 / 2
r = 6 cm
And now, let us find the circumference of the circle using the below formula.
C = 2 π r
C = 2 × 3.14 × 6
C = 37.68 cm
And now let us find the area of the circle using the below formula.
A = π r²
A = 3.14 × 6 × 6
A = 113.04 cm²

help me!!Write a function using correct notation that models the value of each car.
Answer:
[tex]f(x) = 2000 * 1.05^x[/tex]
Step-by-step explanation:
The key to this question is interpreting the graph and then modelling it into an exponential function.
You are given 2 key characteristics of this graph. 1 characteristic being that it intercepts the y-axis at (0,2000), and another characteristic being that it goes through the point (1,2100)
Now refer to the standard form of an exponential function.
[tex]y = a * b^x[/tex]
Since you know that when x = 0, y = 2000, a must be 2000. Because [tex]b^0 = 1[/tex], 2000 * 1 = 2000
So you got your a value. Sub it into the equation and now you got.
[tex]y = 2000 * b^x[/tex]
You still need to solve for b, so this is where you do some algebra. Pick your key point, (1,2100), sub in those values for x and y, and solve for b.
[tex]2100 = 2000 * b^1\\\frac{2100}{2000} = b\\ 1.05 = b[/tex]
Now you have your a and b values. Now you can express using a function:
[tex]f(x) = 2000 * 1.05^x[/tex]
What is the circumference
Find the measure of the arc or angle indicated
Answer:
D) 130
Step-by-step explanation:
So there are three arc sections in this problem,
The first one is given: 158
To find the arc between S and R, you can use the angle of point T and double it.
So:
36 * 2 = 72
The second arc is 72
Now for the one that they want you to find, you have to add the two arcs that you have and substract it from 360, which is the angle of a whole circle
Like so:
360 - (158 + 72) = 130

130
