Please help I'm very confused on this!!

Mathematics
1 answer:
Effectus [21]3 years ago

Step-by-step explanation:

The formula for compound interest is

P = I (1 + r/n)^nt

where

P: the total amount of money in the account after a certain amount of time

I: the principal amount

r: the interest rate as a decimal

n: the number of times a year interest is compounded

t: the number of years passed

For Patrick:

P = 200 (1 + 0.02/12)^12*8

P = 200 (1 + 0.00166667)^96

P = 200 (1.00166667)^96

P = 200 * 1.00166667^96

P = $234.67

For Brooklyn:

P = 200 (1 + 0.04/4)^4*8

P = 200 (1 + 0.01)^32

P = 200 (1.01)^32

P = 200 * 1.01^32

P = $274.99

After 8 years, Patrick has $234.67 and Brooklyn has $274.99

Find the equation of a line in slope intercept form that is perpendicular to the line y = 2x + 6 through the point (10,4)
dalvyx [7]

The equation of the straight line is y = -1/6(x - 10) + 4

<h3>How to determine the line equation?</h3>

The equation is given as:

y = 2x + 6

Linear equations are represented as:

y = mx + c

Where:

Slope = m

So, we have:

m = 6

The slopes of perpendicular lines are represented as:

n = -1/m

So, we have:

n = -1/6

The equation is then represented as:

y = n(x - x1) + y1

This gives

y = -1/6(x - 10) + 4

Hence, the equation of the straight line is y = -1/6(x - 10) + 4

I need help with 5,6,7 please
AlladinOne [14]

Answer:

see explanation

Step-by-step explanation:

the arc length of a circle is calculated as

arc = circumference of circle × fraction of circle

(5)

circumference (C) is calculated as

C = 2πr ( r is the radius )

here diameter = 12 , then r = 12 ÷ 2 = 6

C = 2π × 6 = 12π ≈ 37.7 m ( to the nearest tenth )

(6)

JK = 2πr × \frac{75}{360}

    = 2π × 7 × \frac{5}{24}

    = 14π × \frac{5}{24}

    = \frac{14\pi (5)}{24} ≈ 9.2 in ( to the nearest tenth )

(7)

7.5 = 2πr × \frac{120}{360}

7.5 = 2πr × \frac{1}{3} ( multiply both sides by 3 to clear the fraction )

22.5 = 2πr ( divide both sides by 2π )

r = \frac{22.5}{2\pi } ≈ 3.6 ft
