Lewis checked the balance of his savings
account every month for 4 months. The
balances were $300, $410, $520, and
$630. Would a linear or exponential
function better represent the data?
Explain.
Answers
Answer:
Linear
Step-by-step explanation:
The balances each go up by $110
300 + 110 = 410
410 + 110 = 520
520 + 110 = 630

30.96 m^2
Step-by-step explanation:
Side length of the square is also the diameter of the semicircle so:
r = 0.5 * 12 m = 6 m
Since you want the area of the shaded area, you have to subtract the area of both semi circles from the area of the square:
Square Area - Semi Circle Area - Semi Circle Area = Shaded Region Area
(12 m * 12 m) - (0.5 * 3.14 * 6^2 m) - (0.5 * 3.14 * 6^2 m)
= 144 - 56.52 - 56.52
= 30.96 m^2

find the measure of all of the angles on the diagram
Answers
Answer:
Angle 1: 135*
Angle 2: 45*
Angle 3: 45*
Angle 4: 135*
Angle 5: 135*
Angle 6: 45*
Angle 7: 45*
Angle 8: 135*
Step-by-step explanation:
So we have angle 2, 45*, we can subtract 45 from 180 to get the angle for 1. Since everything is the same size as either 1 or 2 we can just plug in the bigger angle number we have for it, ex 4= 135 and so is 7.
If you don't understand something please don't hesitate to ask.
Answer:
Step-by-step explanation:
∠2 = 45
∠3 = ∠2 {Vertically opposite angles}
∠3 = 45
∠7 = ∠3 {Corresponding angles}
∠7 = ∠45
∠6 = ∠7 {Vertically opposite angles}
∠6 = 45
∠1 + ∠2 = 180 {Linear pair}
∠1 + 45 = 180
∠1 = 180 -45
∠1 = 135
∠4 =∠1 {Vertically opposite angles}
∠4 = 135
∠8 = ∠4 {Corresponding angles}
∠8 = 145
∠5 = ∠4 {Alternate interior angles}
∠5 = 145

Explanation:
x=a+b+4 and a is inversely proportional to y²; b is inverseley propotional to 1/y. when y = 2 x = 18 and when y = 1 x = -3. find x when y = 4
Answers
Answer:
When y = 4, x is equal to 39
Step-by-step explanation:
The given parameters are;
x = a + b + 4
a ∝ 1/y²
b ∝ 1/(1/y) = y
When y = 2, x = 18
When y = 1, x = -3
Therefore, we have;
a·y² = j
a = j/y²
b ∝ 1/(1/y)
∴ b ∝ y
b = k·y
When y = 2, x = 18, we have;
a = j/y² = j/2² = j/4
b = k·y = k·2
x = a + b + 4
∴ 18 = j/4 + k·2 + 4...(1)
When y = 1, x = -3, we have;
a = j/y² = j/1² = j
b = k·y = k·1 = k
x = a + b + 4
∴ -3 = j + k + 4...(2)
Making 'j', the subject of equation (1) and (2) gives;
From equation (1), we have;
18 = j/4 + k·2 + 4
∴ j = (18 - 4 - k·2) × 4 = 56 - 8·k
From equation (2), we have;
-3 = j + k + 4
∴ j = -3 - 4 - k = -7 - k
Equating the two values of 'j', gives;
56 - 8·k = -7 - k
56 + 7 = 8·k - k
63 = 7·k
k = 63/7 = 9
k = 9
From equation (2), we get;
-3 = j + k + 4
k = 9
∴ -3 = j + 9 + 4
j = -3 - 9 - 4 = -16
j = -16
When y = 4, we get;
x = a + b + 4
a = j/y²
b = k·y
∴ x = j/y² + k·y + 4
Plugging in the values of 'j', and 'k' and y = 4, gives;
x = (-16)/y² + 9·y + 4
∴ x = (-16)/4² + 9 × 4 + 4 = 39
x = 39
Therefore;
When y = 4, x = 39.
