Sonny run 4.5 km everyday. One day after he ran 2.5 km, he felt very sick. He walked 0.3 meters before a friend gave him a ride

MAXImum [283]

2 km

4.5km - 2.5km = 2km. The 0.3m is negligible unless it means kilometers. If it is indeed kilometers, it is 1.7km.

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (4, -2)

Point (-1, 8)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{8+2}{-1-4}$
[Fraction] Add/Subtract: $\displaystyle m=\frac{10}{-5}$
[Fraction] Divide: $\displaystyle m=-2$

A garden has the shape of a circular sector such that its straight sides measure 50 feet in length and the central angle is 132°

SOVA2 [1]

Answer:

215 ft

Step-by-step explanation:

The length of the surrounding fence is equal to the perimeter of the garden. That is the sum of the lengths of the straight sides and the curved arc. The arc length is given by the formula ...

s = r·θ . . . . . where θ is the central angle in radians

<h3>arc length</h3>

There are π radians in 180°, so the arc will have a measure in radians of ...

θ = 132° × (π/180°) = 11/15π ≈ 2.3038 . . . . radians

Then the length of the curved side of the garden is ...

s = (50 ft)(2.3038 radian) ≈ 115.2 ft

<h3>perimeter</h3>

The fence length is the sum of the arc length and the two radii:

perimeter = 115.2 ft + 2×50 ft = 215.2 ft

About 215 feet of fencing are needed to enclose the garden.
