Plot the complex number 5i and find its absolute value

cupoosta [38]

Check the picture below.

$\bf 5i\implies \stackrel{a}{0}~~\stackrel{b}{+5}i\implies \stackrel{\stackrel{absolute~value}{modulus}}{r=\sqrt{a^2+b^2}}\implies r=\sqrt{0^2+5^2}\implies r=5$

(0,-1)(5-2)what is the slope

ruslelena [56]

The formula of a slope m:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (0, -1) and (5, -2). Substitute:

$m=\dfrac{-2-(-1)}{5-0}=\dfrac{-2+1}{5}=-\dfrac{1}{5}$

<h3>Answer: The slope = -1/5</h3>

Taylor and Anya are friends who live 63 miles apart. Sometimes on a Saturday, they ride toward each other's houses on their bike

amid [387]

Answer:

Anya rode at 8.5 miles per hour.

Step-by-step explanation:

We have been given that Taylor and Anya live 63 miles apart. One day they left their houses at 8 am and met at 11 am riding toward each other. Taylor rode at 12.5 miles per hour.

We can see that Taylor and Anya met after 3 hours as 11-8=3. This means that both rode their cycles for 3 hours.

Let us find distance covered by Taylor.

$\text{Distance}=\text{Speed*Time}$

$\text{Distance covered by Taylor}=12.5\frac{\text{Miles}}{\text{hour}}*3\text{ hours}}$

$\text{Distance covered by Taylor}=12.5*3\text{ Miles}$

$\text{Distance covered by Taylor}=37.5\text{ Miles}$

Therefore, Taylor covered 37.5 miles in 3 hours.

Let us find distance covered by Anya in 3 hours by subtracting distance covered by Taylor from total distance of 63 miles.

$\text{Distance covered by Anya in 3 hours}=(63-37.5)\text{ Miles}$

$\text{Distance covered by Anya in 3 hours}=25.5\text{ Miles}$

Now let us find speed at which Anya rode bike.

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

$\text{Speed at which Anya rode the bike}=\frac{25.5\text{ Miles}}{3\text{ Hour}}$

$\text{Speed at which Anya rode the bike}=8.5\frac{\text{ Miles}}{\text{ Hour}}$

Therefore, Anya rode the bike at the speed of 8.5 miles per hour.
