Slope is equal to rise divided by one. If you know the horizontal distance (run) in the slope, how can you find the vertical dis

timama [110]

Answer:

By multiplying the run by the slope, we get the rise value

Step-by-step explanation:

Mathematically. we have

slope = rise/run

Now, given that we know the run and we have the value of the slope, how can we get the rise

To get the rise, we simply have to multiply the run by the value of the slope

Hence, multiplying the run by the value of the slope will give the value of the vertical distance which is the rise

Mark simplified 3/5 + 5/8 his work is shown below. Identify where he made his error.

iren2701 [21]

Answer:

Step 1

Step-by-step explanation:

Mark simplified 3/5 + 5/8 using the steps below:

Step 1: 3/5 * 8/5

Step 2: 3 * 8 / 5 * 5

Step 3: 24/5

Step 4: 4 4/5

Mark's error is in Step 1 where he changed the addition sign to multiplication sign.

The correct solution is:

$Step 1: \dfrac{3}{5}+ \dfrac{5}{8}\\Step 2: \dfrac{24+25}{40}\\Step 3: \dfrac{49}{40}\\Step 4: 1\dfrac{9}{40}$

Find the complex zeros of the following polynomial function.

GalinKa [24]

Answer:

$x=\frac{-1\pm\sqrt{3}i}{2}$

Step-by-step explanation:

$f(x)=x^3-1$

$0=x^3-1$

$0=(x^2+2x+1)(x-1)$

$x-1=0$

$x=1$ <-- Real Solution

$x^2+x+1=0$

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-2\pm\sqrt{2^2-4(1)(1)}}{2(1)}$

$x=\frac{-1\pm\sqrt{1^2-4(1)(1)}}{2(1)}$

$x=\frac{-1\pm\sqrt{1-4}}{2}$

$x=\frac{-1\pm\sqrt{-3}}{2}$

$x=\frac{-1\pm\sqrt{3}i}{2}$ <-- Complex Solutions

There is a part-to-whole relationship here.

2 customers : 8 minutes= ? customers : 30 minutes

2/8=x/30

Cross multiply:

8x=60

Divided both sides by 8:

x=60/8=7.5
