A certain forest covers an area of 1700 km^2. Suppose that each year this area decreases by 3.25%. What will the area be after 6
Olenka [21]

y= 1700 (1- .0325) ^15

= 1700(.9675) ^15

=1700(.60920660)

= 1035.65 km

Name one possible cross section of a sphere
Lisa [10]
A "cross section" is basically the two-dimensional face that you get when you cut a three-dimensional figure a certain way.  For example, imagine you're buttering your bread.  When you cut a pat of butter off, what shape is left on the butter?  A square!

So, imagine cutting a ball in half.  What shape is left?  A circle!

Answer: circle

Answer:

Part 1) m∠1 =(1/2)[arc SP+arc QR]

Part 2) PR^{2} =PS*PT

Part 3) PQ=PR

Part 4) m∠QPT=(1/2)[arc QT-arc QS]

Step-by-step explanation:

Part 1)

we know that

The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.

we have

m∠1 -----> is the inner angle

The arcs that comprise it and its opposite are arc SP and arc QR

so

m∠1 =(1/2)[arc SP+arc QR]

Part 2)

we know that

The <u>Intersecting Secant-Tangent Theorem,</u> states that the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.

so

In this problem we have that

PR^{2} =PS*PT

Part 3)

we know that

The <u>Tangent-Tangent Theorem</u>  states that if from one external point, two tangents are drawn to a circle then they have equal tangent segments

so

In this problem

PQ=PR

Part 4)

we know that

The measurement of the outer angle is the semi-difference of the arcs it encompasses.

In this problem

m∠QPT -----> is the outer angle

The arcs that it encompasses are arc QT and arc QS

therefore

m∠QPT=(1/2)[arc QT-arc QS]
