Find the distance between the points (0,-8) and (3,2). Round your answer to the nearest hundredth.
Reil [10]

Answer:

10.44

Step-by-step explanation:

First plot each of the points on to a graph at their respective positions.

Following that create a 90° triangle out of the points. This will create a 3 by 10 triangle. (3 to 0 is 3) (-8 to 2 is a difference of 10)

You can then use the pythagorean theorem a^{2} +b^{2} = c^{2}.

Insert the lengths of each of the sides that we got earlier which would be 3 and 10 into the equation. 3^{2} + 10^{2} = c^{2}

Since we want to find the hypotenuse which is equal to c we work the equation to 9+100 = c^{2} which in turn is 109 = c^{2}

Then take the square root of 109 to remove the square from the c to get c = 10.44

Explain how you can use division to simplify a complex fraction.
PolarNik [594]
Reduce the final answer if needed (or reduce when you multiply).  A mixed number should be converted to an improper fraction (heavier on top) before simplifying. Change the numerator and denominator to single fractions<span> by creating a common denominator</span>

In ΔGHI, the measure of ∠I=90°, the measure of ∠G=62°, and GH = 96 feet. Find the length of IG to the nearest tenth of a foot.
alexandr402 [8]

Answer:

45.1feet

Step-by-step explanation:

Given the following

∠I=90°

∠G=62°, and

GH = 96 feet = Hypotenuse

Required

IG = Adjacent side

Using the SOH CAH TOA identity

Cos theta = Adj/hyp

Cos 62 =IG/96

IG = 96cos62

IG = 96(0.4695)

IG = 45.1feet

Hence the length of IG to the nearest tenth is 45.1feet
