mestny [16]

The expressions of the number of radians can be expressed in the ways below.

<h3>How to write the expressions</h3>

The radius = 1.9 km

The angular speed = 3.1 radians per hour

a. The expression of t from the number of radians

θ = π/2 + 3.1t

<h3>b. Expression from the East</h3>

x = rcosθ

= 1.9cos(π/2 + 3.1t)km

<h3>c. Expression from the north of the center</h3>

= rsinθ

= 1.9sin((π/2 + 3.1t)km

Find the coordinates of the centroid of triangle RST. SHOW YOUR WORK so I can see if the answer makes sense (no links)
zimovet [89]

Note the coordinates of each point: R(-4, 5), S(5, 1), T(2, -3).

The centroid is the point whose coordinates are the average of the coordinates of R, S, and T.

<em>x</em>-coordinate: (-4 + 5 + 2)/3 = 3/3 = 1

<em>y</em>-coordinate: (5 + 1 - 3)/3 = 3/3 = 1

So the centroid is (1, 1).

​Together, teammates Pedro and Ricky got 2673 base hits last season. Pedro had 277 more hits than Ricky. How many hits did each
ioda

Answer:

Pedro got 1520 base hits and Ricky got 1243.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of base hits that Pedro got.

y is the number of base hits that Ricky got.

Pedro and Ricky got 2673 base hits last season.

This means that x + y = 2763

Pedro had 277 more hits than Ricky.

This means that x = y + 277

Replacing in the first equation

x + y = 2763

y + 277 + y = 2763

2y = 2486

y = \frac{2486}{2}

y = 1243

x = y + 277 = 1243 + 277 = 1520

Pedro got 1520 base hits and Ricky got 1243.

Find the distance between the points -18 and -42. Show your work for full credit. (2 points.)
Masja [62]

Answer:

-24

Step-by-step explanation:

Easy way: 42 - 18 = 24, then translate it to negative 24 because your numbers are negative.

A little bit harder way: -42 + (-18) or -42 + 18 = -24
