Answer:
[tex]Area = 45.82m^2[/tex]
Step-by-step explanation:
Given
[tex]d = 10m[/tex] --- diameter
[tex]\theta = 210^\circ[/tex]
Required
Determine the area of the sector
The ares of the sector is calculated as:
[tex]Area = \frac{\theta}{360} * \pi r^2[/tex]
Where
[tex]r = \frac{d}{2}[/tex]
This gives:
[tex]r = \frac{10m}{2} = 5m[/tex]
So, we have:
[tex]Area = \frac{210}{360} * 3.142 * 5^2[/tex]
[tex]Area = \frac{210}{360} * 78.55[/tex]
[tex]Area = \frac{210 * 78.55}{360}[/tex]
[tex]Area = \frac{16495.5}{360}[/tex]
[tex]Area = 45.82m^2[/tex]

if one zero of the following polynomial 8x^2-13x-4k is the reciprocal of the other, then find k
Answer:
k = -2
Step-by-step explanation:
2 way to solve:
1st: 8x²-13x-4k = 8(x²-(13/8)x-(k/2))
if 2 roots: a and 1/a
8(x-a)(x-1/a) = 8(x²-(13/8)x-(k/2))
x²-(a+1/a)x+1 = x²-(13/8)x-(k/2)
1 = -(k/2)
k = -2
2nd: 2 roots of 8x²-13x-4k x=(-b±√b²-4ac)/2a
x = (13±√169-4*8*(-4k))/16 = (13±√169+128k)/16
(13+(√169+128k))/16 = 16/ (13-(√169+128k)) ... root1=1/root2
(13+(√169+128k))*(13-(√169+128k)) = 16*16
13² - (√169+128k)² = 256
169-169-128k = 256
-128k = 256
k = -2

Equivalent fractions

Equivalent fractions always have the same
when modeled, but can have different
.
Every fraction has
equivalent fractions.
Equivalent fractions are fractions that represent the same value or amount, despite having different numerators and denominators.
In other words, equivalent fractions have the same ratio or proportion, but may be written in different forms.
For example, the fractions 1/2 and 2/4 are equivalent fractions because they represent the same amount, which is half of a whole.
Also, 3/5 and 6/10 are equivalent fractions because they both represent three-fifths or 60% of a whole.

Swimming Pool On a certain hot summer's day, 334 people used the public swimming pool. The daily prices are $1.50 for children and $2.00 for adults. The
receipts for admission totaled $588.00. How many children and how many adults swam at the public pool that day ?
Answer: 160 children and 174 adults
Step-by-step explanation:
Let x represent the children and y represent the adults.
Create two equations:
x+y=334
1.50x+2y=588
Subtract 1.50x from the equation, then divide by 2:
y=294 - 0.75x
Plug it into the first equation then solve.
x+294-0.75x=334
x=160
Subtract 160 from 334 to get y:
y=174
A gallon of paint can cover 360 square feet. The radius of a standandard NBA basketball is 4.75 inches. How many basketballs will the paint cover? ( note 144 square inches in 1 square foot )
===========================================================
Explanation:
We're told that 1 square foot is 144 square inches (this is from 12*12 = 144, since 12 inches = 1 ft).
So because of this, 360 square feet converts to 360*144 = 51,840 square inches.
One gallon of paint can cover 51,840 square inches.
Now let's find the surface area of the sphere, aka ball.
It has a radius of r = 4.75 inches, so,
SA = 4*pi*r^2
SA = 4*pi*(4.75)^2
SA = 90.25pi
SA = 283.528736986479 which is approximate
The surface area of one ball is roughly 283.528736986479 square inches.
Divide the amount of area the paint can cover over the surface area of one basketball:
(51,840)/(283.528736986479) = 182.838609415709
This rounds down to 182. We round down because we won't have enough paint to cover the 183rd basketball.
One gallon of paint can cover 182 basketballs.

In a sequence of numbers, a4=6, a5=10, a6=14, a7=18, and a8=22. Which recursive rule can be used to find the nth term of the sequence, an?

a1=−6; an=4an−1
Common difference
a_5-a_410-64Equation
a_n=a+(n-1)4a_5=a+16a=10-16a=-6Option B
Answer:
[tex]\begin{cases} \sf a_1=-6 \\ \sf a_n=a_{n-1}+4 \end{cases}[/tex]
Step-by-step explanation:
Given:
a₄ = 6a₅ = 10a₆ = 14a₇ = 18a₈ = 22From inspection of the given terms, it is evident that there is a common difference between consecutive terms. Therefore, this is an arithmetic sequence.
A recursive formula for an arithmetic sequence allows you to find the nth term of the sequence provided you know the value of the previous term in the sequence.
From inspection of the sequence, we can see that each term is found by adding 4 to the previous term. Therefore, the recursive formula is:
[tex]\sf a_n=a_{n-1}+4[/tex]
A recursive rule comprises the recursive formula together with the 1st term a₁. To find the 1st term, keep subtracting 4 from each term:
[tex]\begin{aligned} \sf a_3 & = \sf a_4 - 4\\ & = \sf 6 - 4\\ & = \sf 2\end{aligned}[/tex]
[tex]\begin{aligned} \sf a_2 & = \sf a_3 - 4\\ & = \sf 2-4 \\ & = \sf -2\end{aligned}[/tex]
[tex]\begin{aligned} \sf a_1 & = \sf a_2 - 4\\ & = \sf -2-4 \\ & = \sf -6\end{aligned}[/tex]
Therefore, the recursive rule that can be used to find the nth term of the sequence is:
[tex]\begin{cases} \sf a_1=-6 \\ \sf a_n=a_{n-1}+4 \end{cases}[/tex]

Find a Quadratic equation whose roots are 1.5+√2 and 1.5-√2
Answer:
x² - 3x + 0.25 = 0
Step-by-step explanation:
Given a root x = a then the corresponding factor is (x - a)
Given roots x = 1.5 + [tex]\sqrt{2}[/tex] and x = 1.5 - [tex]\sqrt{2}[/tex] then the factors are
(x - (1.5 + [tex]\sqrt{2}[/tex] ) ) and (x - (1.5 - [tex]\sqrt{2}[/tex] ) ) , that is
(x - 1.5 - [tex]\sqrt{2}[/tex] ) and (x - 1.5 + [tex]\sqrt{2}[/tex] )
The equation is then the product of the factors
(x - 1.5 - [tex]\sqrt{2}[/tex] )(x - 1.5 + [tex]\sqrt{2}[/tex] ) = 0 ← expand factors using FOIL
(x - 1.5)² - ([tex]\sqrt{2}[/tex] )² = 0
x² - 3x + 2.25 - 2 = 0
x² - 3x + 0.25 = 0

Blin and Alex raised a total of $240,000 for a charity. If Blin raised $60,000 more than Alex did, how much money did Blin raise?
Answer:
180000
Step-by-step explanation:
Solve
Given: Both Raised $240,000, Blin raised $60,000 more than Alex
To find: How much money Blin raised
Firstly, since two people raised that amount, divide the amount by 2 of them
240,000 ÷ 2 = 120,000
Nextly, subtract 60,000 from Alex's share; because Brin has more so Alex has less, less means subtract.
120,000 - 60,000 = 60,000
Now, Add that amount to Brin's share; again, Brin has more so Alex has less, less means subtract.
60000 + 120,000 = 180,000
Therefore, Brin raised $180,000
Confirm: 180,000 + 60,000 = 240,000
(For your information, Alex has $60,000)

Which of the following statements are true about the graph of f(x) = 6(x + 1)2 -9?
Check all of the boxes that apply.
a. The vertex is (1, -9).
b. The graph opens upward.
c. The graph is obtained by shifting the graph of f(x) = 6(x + 1)2 up 9 units.
d. The graph is steeper than the graph of f(x) = x2.
e. The graph is the same as the graph of f(x) = 6x2 + 12x - 3.
Answer:
Step-by-step explanation:
a. The vertex is (1, -9). False. The vertex is (-1, -9).
b. The graph opens upward. True. That coefficient '6' is positive.
c. The graph is obtained by shifting the graph of f(x) = 6(x + 1)2 up 9 units. False. It's DOWN 9 units.
d. The graph is steeper than the graph of f(x) = x^2. True. The given function increases 6 times faster than does x^2.
e. The graph is the same as the graph of f(x) = 6x2 + 12x - 3.
Let's put f(x) = 6(x + 1)^2 -9 into standard form. Expanding the first term, we get f(x) = 6(x^2 + 2x + 1) - 9, or f(x) = 6x^2 + 12x + 6 - 9. YES, TRUE

Answer:
The missing numbers are 12 and 39 respectively
Step-by-step explanation:
From the table, we can see that the ratio of the left column to the right is 3/5
So at any point in time, the values on a particular row of the table must conform
to this ratio
In other light, we have to multiply what we have on the left by 5/3 to get what’s on the right
and we have to multiply what we have on the right by 3/5 to get what’s on the left
We have this as follows;
20 * 3/5 = 12
