Answer:

As per the given statement: A forest ranger wants to determine the radius of the trunk of a tree. She measures the circumference to be 8.6 feet.

Shape of the trunk of a tree is circle.

Use the circumference formula:

C = 2\pi r

where C is the circumference of a circle and r is the radius of a circle.

Solve for r;

Given: C = 8.6 feet and use \pi = 3.14

Substitute the given value we get;

8.6 = 2 \times 3.14 \times r

Simplify:

8.6 = 6.28r

Divide both sides by 6.28 we get;

r = 1.6942675 feet

Therefore, the trunk's radius to the nearest tenth foot is, 1.4 ft

Question
1.Wanda took out a personal loan for $5,000 at 9% simple interest. How much interest will she pay after 5 years? (SHOW YOUR WORK) 2.Suppose she pays off the loan in 1 years instead of 5 years. How much money will she save in interest? (SHOW YOUR WORK)
Solution 1
1.) First, you use the formula for finding the simple interest, which is I = Prt

I = PRT
I = 5,000 x 0.09 x 5
I = 450 x 5
I = $2,250

2.) Since it says 1 year instead of 5, you multiply 450 by 1. So she only pays $450. To get how much money she'll save in interest, you subtract 2,250 by 450, which equals 1,800. So, she'll save $1,800 in interest.

Solution 1
So the given is 4.6 cm and you're trying to find the amount of km.
GIVEN: 2 cm = 1 km
4.6/2 = 2.3 km
Solution 2

2.3

since 2 cm=1k you divide by 2

Question
Which expression gives the distance between the points (5, 1) and (9, -6)?
Solution 1

Answer:

d = \sqrt{65}\text{ units}

Step-by-step explanation:

Let (x_1,x_2) and (y_1, y_2) be the two points.

We have to find the distance between the two points.

The distance Formula:

d = \sqrt{(x_1 - y_1)^2 + (x_2 - y_2)^2}

Here, we are given (x_1,x_2) = (5,1) and  (y_1, y_2)  = (9,-6)

Then, the distance between these two points is given by:

d = \sqrt{(5 - 9)^2 + (1- (-6))^2}

d = \sqrt{(-4)^2 + (7)^2}

d = \sqrt{16 + 49}

d = \sqrt{65}

Thus, the distance between the given point is \sqrt{65}\text{ units}.

Solution 2
So the distance formula: d = rad (x2 - x1)^2 + (y2 - y1)^2
it doesn't matter what order you do, you just have to make sure it's a y coordinate for y and an x coordinate for x.
rad (9-5)^2 + ((-6)-1)^2
rad 4^2 + (-7)^2
rad 16 + 49
rad 65
