Answer:

12 miles

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

let x be the distance from the Park to the Library, then

x² + 5² = 13²

x² + 25 = 169 ( subtract 25 from both sides )

x² = 144 ( take the square root of both sides )

x = \sqrt{144} = 12

Answer:

12 mi.

Step-by-step explanation:

a^2+b^2=c^2

c is the hypotenuse (the line across the right angle) and a and b are the other sides.

a=5

c=13

Plug into the equation

5^2+b^2=13^2

b^2=169-25

b^2=144

b=12

What is the graph of y=-(x-2)^3-5
natulia [17]
When x=0,
y=-(0-2)^3-5
y=3

When y=0,
(x-2)^3=5
x-2= +/- 5^1/3
x= +/- 5^1/3 +2
x= 3.70997 or x=0.29002

To find the turning point at y, substitute the information that you have found above.

y=-(3.70997-2)^3-5
y=-9.99994

Find the mid-point next as mid-point is also the turning point.

(3.70997+0.29002)÷2=1.999995

Hence, Turning point is (1.999995, 9.99994)

Plot a graph using turning point, y value and the 2-x values.

WORTH 49 POINTS! How far away is -5 to |-5|?
diamong [38]

|-5| is equivalent to 5, since that is how far -5 is from 0.

So, the question is simplified to: How far away is -5 from 5?

We get 5-(-5)=10.


Remember, absolute value is always positive (expect for 0) and the distance between two numbers is always positive (expect for 0).

I Need help! If you help me you'll get 10 points!!
natka813 [3]

To solve this problem you must apply the proccedure shown below:

1. You have that the number of innings are expressed as a mixed number in the exercise:

102^{\frac{2}{3} }

2. If you want to write it as a decimal, you can convert the fraction as a decimal by dividing the numerator by the denominator and then, you must add this to the whole number part:

102+\frac{2}{3}=102+0.67=102.67

The answer is: 102.67
