Answer:

1) Missing Length: 20 m

Equation: c^2=16^2+12^2

2) Missing Length: 100√5 mm

Equation: c^2=100^2+200^2

Step-by-step explanation:

1) We can use Pythagorean Theorem to solve this triangle and find the length of the hypotenuse.

c^2=16^2+12^2

c^2=256+144

c^2=400

Luckily, 400 is a perfect square :)

c=20

So, the length of the hypotenuse is 20 cm.

2) Again, we can use the Pythagorean Theorem to find the missing length.

c^2=100^2+200^2

c^2=10000+40000

c^2=50000

c=\sqrt{50000}

But, we can still simplify the radical.

\sqrt{50000}

=100\sqrt{5}

So, the length of the missing length is 100√5 cm.

    ¹/₄                                        25%                                         0.25

    ¹/₂                                        50%                                           0.5

    ²/₃                                      66.6%                                        0.6

Fraction;

25/100 = 1/4

66.6/100 = 2/3

Percentage

1/5 * 100 = 20%

1/2 * 100 = 50%

Decimal

1/5 = 0.2

25/100 = 0.25

1/2 = 0.5

What is the equation of the line that goes through (-5,0) and (-4,4)
Tasya [4]

Answer:

y=4x+20

Step-by-step explanation:

To write an equation, use the slope-intercept equation:

y=mx+b

M is the slope and b is the y-intercept.

First, find the slope by using the slope formula for when you have two points:

\frac{y(2)-y(1)}{x(2)-x(1)}=\frac{rise}{run}

Rise over run is the change in the y-axis over the change in the x-axis. Substitute values:

(-5,0)(-4,4)\\(-5(x1),0(y1))\\(-4(x2),4(y2))\\\\\frac{4-0}{-4-(-5)}

Simplify parentheses (two negatives make a positive) and simplify:

\frac{4-0}{-4+5}\\\\\frac{4}{1}=4

The slope, m, is 4. Insert this information into the equation:

y=4x+b

Now, take one of the points and insert into the slope-intercept formula:

(-5,0)\\(-5(x),0(y))\\\\0=4(-5)+b

Solve for b, the y-intercept. Simplify multiplication:

0=-20+b

Add 20 to both sides and simplify:

0+20=-20+20+b\\20=b\\b=20

The y-intercept, b, is 20. Insert this value into the equation:

y=4x+20

Done.
