Answer: 4/-3

Step-by-step explanation:

If the points are (7,1) and (4,5), you use those to find the slope, which is described at the change in y divided by the change in x. So:

(5-1)/(4-7)= 4/-3

On my sister's 15th birthday, she was 159 cm in height, having grown 6% since the year before. How tall was she the previous yea

Zarrin [17]

It means that her height in this year is $106\%x$ in regards to the last year, where x is her height in last year, so:

$159=106\%x$

$159=\frac{106}{100}x$

$159=\frac{53}{50}x$

$159*50=53x$

$159*50=53x$

$7950=53x$

$150=x$

If the area of a sector is 100 ft^2 and the radius of the circle is 22 ft what is the central angle measure for that sector and

ahrayia [7]

Answer:

$\displaystyle \theta=0.413\ rad$

Step-by-step explanation:

<u>Area of a Circular Sector</u>

Given a circle of radius r, the area of a circular sector defined by a central angle θ (in radians) is given by

$\displaystyle A=\frac{1}{2}r^2\theta$

And the length of the arc is:

$L=\theta r$

We know the area of the sector is 100 square feet and the radius is r=33 ft, thus:

$\displaystyle 100=\frac{1}{2}r^2\theta$

Solving for θ:

$\displaystyle \theta=\frac{200}{r^2}$

$\displaystyle \theta=\frac{200}{22^2}$

$\displaystyle \theta=0.413\ rad$

The arc length is:

$L=0.413* 22$

L= 9.086 feet
