Find the number of rectangles an and Squares in chess 8 by 8 board respectively.
Answer:
squares: 204
rectangle: 1,296
Step-by-step explanation:
Board Size: 8 x 8
The total number of squares is thus:
[tex]1^{2} + 2^{2} + ... + n^{2}[/tex]
sum = [tex]\frac{n(n + 1)(2n + 1)}{6}[/tex]
For a chess board, with n = 8,
sum = [tex]\frac{(8)((8) + 1)(2(8) + 1)}{6}[/tex]
sum = 204
the number of rectangles on a chess board,
to make a rectangle you need to pick any two of the vertical lines, and any two of the horizontal lines. There are 36 distinct pairs and the same number of vertical pairs, so the answer is 36 × 36 = 1,296.

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The triangle is shown in figure.
Now,
Since, We know that;
The sine rule is;
⇒ sin A / a = sin B / b = sin C / c
By given figure, we get;
⇒ sin 83° / x = sin 68° / 13
⇒ sin 83° × 13 / sin 68° = x
⇒ x = 0.99 × 13 / 0.92
⇒ x = 13.9

There are a rack of 14 billiard balls. Balls numbered 1 through 8 are solid-colored. Balls numbered 9 through 14 contain stripes. If one ball is selected at random, determine the odds against it being striped.
Answer:
3/7 / 42.8% chance
Step-by-step explanation:
There are 6 striped balls (9, 10, 11, 12, 13, 14) and 8 (1, 2, 3, 4, 5, 6, 7, 8) solid colored balls. So, 6 / 14 balls are striped.
(6 / 14 = 3 / 7)
this means that the probability of a ball being striped has the odds of 3/7
(3/7 = about 42.8% chance)

Photo is attached!!!!!! Pleaseeee help!!!
Answer:
1.) ∞
2.) -∞
3.) 0
4.) 0
Step-by-step explanation:
As you approach x = -2 from the left, the "y" values are going to infinity. You never actually get a "y" value that equals x = -2 because of the vertical asymptote.
As you approach x = -2 from the right, the "y" values are going to -infinity. You never actually get a "y" value because there is a vertical asymptote.
As you approach x = 2, both sides converge to y = 0. At this point, there is a smooth, uninterrupted line.
The actual "y" value at x = 2 is 0 because the function goes straight through this point. So, you can just read this point as usual.

The secant line can be used to approximate the derivative at a particular point on the graph by placing either the right or the left side of the secant line on that point. (Round your answer to the nearest integer.)
(a) Consider the point on the graph at t = 10 days and set one end of the secant line at this point. Set the other end of the secant line at the point that is 1 day earlier. What is the approximation of the slope of the graph at t = 10 days using this secant line?
(b) Consider again the point on the graph at t = 10 days. Set one end of the secant line at t = 10 days and the other end at the point that is 1 day later. What is the approximation of the slope of the graph at t = 10 days using this secant line?
The approximation of the slope of the graph at t = 10 days using this secant lines are 11750 and -11750, respectively.
How to determine the slope of the secant lines?(a) t = 10 days and a day earlier
This means that:
t = 10 and t = 9
The function is given as:
[tex]N(t) = 100000e^{\frac{-(t - 10)^2}{8}}[/tex]
Calculate N(10)
[tex]N(10) = 100000e^{\frac{-(10 - 10)^2}{8}}[/tex]
Evaluate
N(10) = 100000
Next, calculate N(9)
[tex]N(9) = 100000e^{\frac{-(9 - 10)^2}{8}}[/tex]
Evaluate
N(9) = 88249.6902585
The slope is then calculated using"
[tex]m = \frac{N(10) - N(9)}{10 - 9}[/tex]
This gives
[tex]m = \frac{100000 - 88249.6902585}{10 - 9}[/tex]
Evaluate
m = 11750.3097415
Approximate
m = 11750
(b) t = 10 days and a day later
This means that:
t = 10 and t = 100
The function is given as:
[tex]N(t) = 100000e^{\frac{-(t - 10)^2}{8}}[/tex]
In (a), we have:
N(10) = 100000
Next, calculate N(11)
[tex]N(9) = 100000e^{\frac{-(11 - 10)^2}{8}}[/tex]
Evaluate
N(11) = 88249.6902585
The slope is then calculated using:
[tex]m = \frac{N(11) - N(10)}{11 - 10}[/tex]
This gives
[tex]m = \frac{88249.6902585 - 100000}{11 - 10}[/tex]
Evaluate
m = -11750.3097415
Approximate
m = -11750
Hence, the approximation of the slope of the graph at t = 10 days using this secant lines are 11750 and -11750, respectively.

Based on the calculations, the sequence defined by the given function are 0.75, 1.1, 1.45, 1.80 and 2.15.
How to create the terms of the sequence?In this exercise, you're required to create the first five (5) terms of the sequence defined by the given function as follows:
For the first term, we have:
f(1) = 0.75
For the second term, we have:
f(2) = f(2-1) + 0.35
f(2) = 0.75 + 0.35
f(2) = 1.1.
For the third term, we have:
f(3) = f(3-1) + 0.35
f(3) = 1.1 + 0.35
f(3) = 1.45.
For the fourth term, we have:
f(4) = f(3-1) + 0.35
f(4) = 1.45 + 0.35
f(4) = 1.80.
For the fifth term, we have:
f(5) = f(3-1) + 0.35
f(5) = 1.80 + 0.35
f(5) = 2.15.

Diana put $8000 in a 10-year CD
paying 5% interest compounded
monthly. After 2 years, she
withdrew all her money, and as an
early withdrawal penalty, she paid
back all the interest she made
during the first year. How much
money was Diana left with?
Th amount of money that Diana is left with is $8,430.23.
How much is Diana left with?The first step is to determine the interest earned in the first year and the total amount that was made in the 2 years.
The formula used to determine the future value with monthly compounding is:
P(1 + r)^( n x m)
Where:
P = present value r = periodic interest rate n = number of years m = frequency of compoundingTotal amount made in 2 years = $8000 x ( 1 + 5% / 12)^(12 x 2) = 8839.53
Interest earned in the first year = [ $8000 x ( 1 + 5% / 12)^(12) ] - 8000 = $409.29
Amount she is left with = 8839.53 - $409.29 = $8430.23

compound interest is just an exponential sequence really, where the next value is some exponential amount of the previous.
hmmm that can happen in say, a bouncing ball, the 1st bounce is high, let it keep on boucing by itself and the next bounce is usually a compounded value of the previous one, since it's smaller it'd be a Decay type of equation.

Step-by-step explanation:
a) First bring all the fractions to a common denominator (I'm going to use 8th's). 5/8 is already simplified, 1/2=4/8, and 3/4=6/8. Then, simply add the numerators and leave the denominator: [tex]\frac{5+4+6}{8} =\frac{15}{8}[/tex]
Since this can not be simplified any further, your final answer is 15/8.
b) Start by bringing all the fractions to a common denominator (for this problem, we'll use 18th's). 2/3=12/18, 1/6=3/18, and 5/9=10/18. Then just add all the numerators and leave the denominator the same: [tex]\frac{12+3+10}{18} = \frac{25}{18}[/tex]
Since this cannot be simplified further either, your final answer is 25/18.
