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:

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

Substitute the given value we get;

Simplify:

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.)Â 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.

Question
On a map with a scale of 2 cm = 1km, the distance from Beau's house to the beach is 4.6 centimeters. What is the actual distance?
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
Choose the correct simplification of the expression (7m3 n) 2. 14m5n3 14m6n2 49m5n3 49m6n2
Solution 1
For this case we have the following expression:
Â (7m ^ 3n) ^ 2
Â By power properties we can rewrite the expression as:
Â ((7 ^ 2) (m ^ (3 * 2)) (n ^ 2))
Â Then, simplifying we have:
Â (49 (m ^ 6) (n ^ 2))
Â
the correct simplification of the expression is:
Â
(49 (m ^ 6) (n ^ 2))

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

Step-by-step explanation:

Let and be the two points.

We have to find the distance between the two points.

The distance Formula:

Here, we are given = (5,1) and Â  Â = (9,-6)

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

Thus, the distance between the given point is .

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.
