Answer:

  4 1/6 miles per hour

Step-by-step explanation:

6 minutes is 1/10 hour, so Sara's speed is ...

  speed = distance/time

  speed = (5/12 mi)/(1/10 h) = 50/12 mi/h

  speed = 4 1/6 mi/h

Sara's speed is 4 1/6 miles per hour.

Find three consecutive positive integers such that the square of the first is equal to the Third
Anna71 [15]
3 consecutive positive integers : x, x + 1, x + 2

x^2 = x + 2
x^2 - x - 2 = 0
(x + 1)(x - 2) = 0

x + 1 = 0
x = -1....this is an extraneous solution that does not work

x - 2 = 0
x = 2

check...
square of the first = third
x^2 = x + 2
2^2 = 2 + 2
4 = 4 (correct)

so ur 3 integers are 2,3, and 4

A person places $82100 in an investment account earning an annual rate of 4.3%, compounded continuously. Using the formula V = P
SVETLANKA909090 [29]

Answer:

$89,472.58

Step-by-step explanation:

P = $82100

r = 4.3% = 4.3/100 = 0.043

T = 2 years

V = P × e^rt

V = 82100 × e^(0.043 × 2)

V = 82100 × e^(0.086)

V = 82100 × 1.0898

V = 89,472.58

The interest after 2 years is $89,472.58
