Rachel currently has $836 in a savings account that has earned 4. 5% annual compound interest for the past year. What was Rachel’s beginning balance one year ago if she has made no other deposits during the year?
Answers
Rachel's beginning balance one year ago was $800.
What is compound interest?Compound interest is applicable when there will be a change in the principle amount after the given time period.
For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.
Given that,
The current balance is $836 which is the result of compound interest of 4.5 % annually.
The original amount was a priciple amount P on which interest was applied and the final amount $836 made.
Compound interest formula;
A = P[ 1 + RT/100]^T
Where A is the final amount and T is the time period.
Here,
A = 836 , R = 4.5% and T = 1 year.
So,
836 = P[1 + 4.5/100]^1
P = 836/1.045 = $800
Hence "Rachel's beginning balance one year ago was $800".

Steps:
The Arithmetic Series formula is:
S = n( (a1 + an) / 2)
Take note that:
S = the sum of n terms
n = number of terms
a1 = the first term
an = the last term
We are given n, a1, an. Let’s solve for S.
S = 20( (18 + 28) / 2)
18 + 28 = 46
46 / 2 = 23
20 * 23 = 460
The depth of two lakes is measured at multiple spots. For the first lake, the mean depth is about 45 feet with a mean absolute deviation of 8 feet. For the second lake, the mean depth is about 60 feet with a mean absolute deviation of 27 feet.
Noah says the second lake is generally deeper than the first lake. Do you agree with Noah?
No, I do not agree with Noah because the second lake has greater variability with a higher MAD so even though the mean depth is deeper the data is very spread out away from that mean.
No, I do not agree with Noah. The MAD tells us how deep it is and the 1st MAD is more.
Yes, I agree with Noah. The MAD tells us how deep it is and the second MAD is more.

Which is a larger volume, a candle with a height of 6. 3 inches and a radius of 3. 1 inches, or a candle with both a height and a radius of 3. 9 inches?
Answers
H = height
R = Radius
A = area
Volume of a cylinder = A x H
Area of circle = Pi x (R^2)
Label the candles, Candle X and Candle Y
(X being the one with 3.1 inches and Y being the one with 3.9)
*CANDLE X*
3.1 x 3.1 = 9.61
9.61 x pi (3.14) = 30.1754
30.1754 x H (6.3) = 190.10502cm^3
*CANDLE Y*
3.9 x 3.9 = 15.21
15.21 x pi (3.14) = 47.7594
47.7594 x H (3.9) = 186.26166cm^3
CANDLE X HAS THE LARGER VOLUME BY 3.84336CM^3

Two theorems we are proving are:
Line drawn from the center of the circle to bisect a chord is perpendicular to it.Perpendicular drawn from the center of the circle to a chord, bisects it.How do we solve the given question?Part A: The image is attached
Part B:
Let there be a circle with the center at O. Let AC be a chord. Let OE be a radius of the chord such that OE bisects AC at B, that is, AB = BC.
To prove: A line drawn from the center of the circle to bisect a chord is perpendicular to it.
Construction: We join OA and OB.
Proof:
In ΔOAB and ΔOCB,
OA = OC (Radius of the same circle)
AB = BC (Given, at B, the chord is bisected)
OB = OB (common side)
∴ ΔOAB ≅ ΔOCB [SSS axiom]
∴ ∠OBA = ∠OBC [Common parts of Congruent triangles]
Let ∠OBA = ∠OBC = x.
Since AC is a straight line,
∠OBA + ∠OBC = 180° [Linear pair]
or, x + x = 180°
or, 2x = 180°
or, x = 90°.
∴ ∠OBA = ∠OBC = 90°.
So, we can say that OB ⊥ AC, hence the theorem is proved.
Part C: The image is attached
Part D:
Let there be a circle with the center at O. Let AC be a chord. Let OE be a radius of the chord such that OE is perpendicular to AC at B, that is, AB ⊥ BC.
To prove: A line drawn from the center of the circle perpendicular to the chord bisects it.
Construction: We join OA and OB.
Proof:
In ΔOAB and ΔOCB,
OA = OC (Radius of the same circle)
∠OBA = ∠OBC = 90° (∵ OB ⊥ AC)
OB = OB (common side)
∴ ΔOAB ≅ ΔOCB [RHS axiom]
∴ AB = AC [Common parts of Congruent triangles]
So, we can say that OE perpendicular to the chord AC bisects it, hence the theorem is proved.

Statement 2:
The domain of this relation is 3=< x =< 8.
Statement 3:
The range of this relation is {6, 7, 8, 10}
Answers
Answer:
Statement 1 - false
A function is one-to-one or many-to-one.
One-to-one means each value in the range (y-values) corresponds to exactly one value in the domain (x-values)
Many-to-one means some values in the range (y-values) correspond to more than one (many) value in the domain (x-values).
Therefore, as some y-values correspond to more than one x-value, this is a many-to-one function.
The true statement should be:
The relation is a function because some y-values correspond to more than one x-value.
Statement 2- true
The domain is the set of input values (x-values). Therefore, the domain is 3 ≤ x ≤ 8 as the smallest x-value is 3 and the highest x-value is 8.
Statement 3 - true
The range is the set of output values (y-values). Therefore, the range is {6, 7, 8, 10} as these are the y-values of the ordered pairs.

The total of Melinda's expenses for the week is $93.04 option (c) $91.94 is correct.
What is expenses?It is defined as the money spends on the utility, the amount of money is required to buy something in other words it is the outflow of money from the solely earners income or the money incurred by any organization.
Melinda kept a record of her spending for the week as follows:
The amount she spent money to put gas in the car = $25
The amount to buy a new shirt = $22.38
The amount to play putt-putt golf with some friends = $6.95
The amount to buy groceries = $38.71
To calculate the total expenses for the week, we must add all the expenses:
= $25+$22.38+$6.95+38.71
= $93.04
Thus, the total of Melinda's expenses for the week is $93.04 option (c) $91.94 is correct.

b) y=3x-22
c) y=3x+2
d) y=3x+22
Answers
Answer:
y = 3x -2
Step-by-step explanation:
General equation of a line in the slope intercept form is
y = mx + b ,
where m is the slope and b is the y-intercept ( where intercepts the y-axis)
y = 3x + b ,
because is given slope is m = 3
For point (x = -2, y = -8) we have
-8 = 3 (-2) + b
-8 = -6 + b
-8 + 6 = b
