Hi can u plzz help me with these thank you!!!

Answer:

1.

Radius = 5ft

Circumference = 31.4\ ft

2.

Perimeter = 25.12\ ft

Step-by-step explanation:

Solving (1):

Given

Diameter = 10ft

Required

Determine the radius and circumference

Radius is calculated as follows:

Radius = \frac{1}{2} * Diameter

Radius = \frac{1}{2} * 10ft

Radius = 5ft

The circumference is calculated using:

Circumference = 2 * \pi * Radius

Circumference = 2 * 3.14 * 5ft

Circumference = 31.4\ ft

Solving (2):

Given

R = 4ft

Assume that the window is circular, the perimeter is calculated as follows:

Perimeter = 2 * \pi * R

Perimeter = 2 * 3.14 * 4ft

Perimeter = 25.12\ ft

An investment of $100 is now valued at $149.18 the interest rate is 8% compounded continuously about how long has the money been
deff fn [24]

question: An investment of $100 is now valued at $149.18 the interest rate is 8% per year, compounded continuously about how long has the money been invested

Answer:

5.2 years

Step-by-step explanation:

Applying

A = P(1+R/100)ⁿ.......................... Equation 1

Where A = amount, P = principle, R = rate, n = time.

From the question,

Given: A = $149.18, P = $100, R = 8%

Substitute these values into equation 1 and solve for n

149.18 = 100(1+8/100)ⁿ

149.18/100 = (1+8/100)ⁿ

1.4918 = (1+0.08)ⁿ

1.4918 = (1.08)ⁿ

Taking the Logarithm of both side

Log(1.4918) = Log(1.08)ⁿ

Log(1.4918) = nLog(1.08)

n = Log(1.4918)/Log(1.08)

n = 0.1737/0.0334

n = 5.2 years.

The value of y in the system of equations is:
nirvana33 [79]
Y=1
Explanation:
You have to plug 2+x into the y of the first equation. After you solve that you should get-1 as the answer for x so you plug -1 into the x of the second equation and the value of y would be 1.
