Answer:
ok
Step-by-step explanation:
Interest I = PRT /100
P = $ 1000
R = 5.5% per annum
T = 18 months = 18 /12 = 1.5 years.
I = 1000 * 5.5 * 1.5 /100
I = $ 82.5
Amount = P + I = 1000 + 82.5 = 1082.5.
Hence the it would have grown to $1082.5
Answer:
The top left answer is correct.
Step-by-step explanation:
If you take each ordered pair and put them in the form y/x. The top left corner is the only one where all of the equations are equivalent.
7/1 = 21/3 = 35/5 = 49/7
2x^2 - 5x + 12 = 0
Factoring out the leading coefficient:
2(x^2 - 5/2 x) + 12 = 0
Completing the square:
2[(x - 5/4)^2 - 25/16] + 12 = 0
2(x - 5/4)^2 - 25/8 + 12 = 0
2(x - 5/4)^2 + 71/8 = 0
q = 71/8
Answer:
Step-by-step explanation:
See the attached figure.
y₁ = 25x and y₂ =x²
The intersection between y₁ and y₂
25x = x²
x² - 25x = 0
x(x-25) = 0
x = 0 or x =25
y = 0 or y =25² = 625
The points of intersection (0,0) and (25,625)
To find the volume of the solid obtained by rotating about the y-axis the region bounded by y₁ and y₂
y₁ = 25x ⇒ x₁ = y/25 ⇒ x₁² = y²/625
y₂ =x² ⇒ x₂ = √y ⇒ x₂² = y
v = ∫A(y) dy = π ∫ (x₂² - x₁²) dy
∴ V =
