One angle of a right triangle measures 60°. The side opposite this angle measures 15 inches.
Delicious77 [7]

Step-by-step explanation:

To solve this question I would use the sin rule.

The sin rule states that

\frac{a}{ \sin(a) }  =  \frac{b}{ \sin(b)  }

Therefore if you substitute in your numbers you get:

\frac{a}{ \sin(90) }  =  \frac{15}{ \sin(60) }

If you rearrange that you get:

a =  \frac{15}{ \sin(60) }  \times  \sin(90)

Therefore a = 17.3 Inches (to 3 sf)

This can also be done with basic trigonometry where you would get

\sin(60)  =  \frac{15}{h}

Rearranging to

h =  \frac{15}{ \sin(60) }

meaning the answer is 13.7 inches

The number of users on a website is 630 and is growing exponentially at a rate of 76% per year. Write a function to represent th
Dafna1 [17]

The exponential function that represents the number of users on the website after t is given by:

A(t) = 630(1.76)^t

The daily rate of change is of 20.82%.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the growth rate, as a decimal.

For this problem, the parameters are given as follows:

A(0) = 630, r = 0.76

Hence the equation that represents the number of users on the website after t is given by:

A(t) = 630(1.76)^t

An year has 365 days, hence the rate of change per day is given by:

76/365 = 0.2082 = 20.82%.

The daily rate of change is of 20.82%.

What is the radius of a circle with the equation x2 + y2 – 14x + 10y = 250?
ololo11 [35]
X2 + y2 - 14x + 10y = 250
x2 -14x + 49 - 49 + y2 + 10x + 25 - 25 = 250
(x - 7)^2 - 49 + (y+5)^2 - 25 = 250
(x-7)^2 + (y+5)^2 = 250 + 49 + 25
(x-7)^2 + (y+5)^2 = 324

Therefore the radius, r
r = 324^0.5
r = 18
