A cyclist travels a distance of 837 1/2 feet in 25 seconds. The cyclist travels at a constant rate. What is the unit rate, in fe

wel

Answer:

$\boxed{33.5 \ \text{feet/second}}$

Step-by-step explanation:

To find the unit rate, we need to find out how much distance does the cyclist travel in 1 second. For that, we need to use the unitary method. A unitary method is a method that determines the unit rate of an object.

Note: Since the cyclist travels at a constant rate, unitary method can be used.

$\rightarrow 837 \dfrac{1}{2} \ \text{feet in 25 seconds}$

$\rightarrow 837.5 \ \text{feet} = 25 \ \text{seconds}$

Divide both sides by 25:

$\rightarrow \dfrac{837.5}{25} \ \text{feet} = \dfrac{25}{25} \ \text{seconds}$

$\rightarrow 33.5 \ \text{feet} = 1 \ \text{seconds}$

$\rightarrow \boxed{33.5 \ \text{feet/second}}$

Determine the mechanical energy of this object a 1kg pendulum at a height of 1-meter

Lemur [1.5K]

Answer:

Step-by-step explanation:

Mechanical energy (ME) is Kinetic energy + potential energy

Where

Kinetic Energy (KE) = 1/2 * m * v^2

where m is the mass (in kg) and v is the speed of the object (in m/s)

and

Potential Energy (PE) = m*g*h

Where m is the mass (in kg) and g is the gravitational constant (9.81 m/s) and h is the height (in meters)

Hence

ME = KE + PE (note the pendulum DOES NOT have any speed, so v = 0, and thus KE = 0)

So,

$ME=KE+PE\\ME=\frac{1}{2}mv^2+mgh\\ME=\frac{1}{2}(1)(0)^{2}+(1)(9.81)(1)\\ME=0+9.81\\ME=9.81$

Hence, Mechanical Energy is 9.8 Joules (rounded to 1 decimal place). Correct answer is A.

Calculate the slope between the points: (4, -9) and (5, 1)

12345 [234]

Answer:

The answer is A- m=10

Step-by-step explanation:

The way to find slope is known as "Rise over Run" meaning the increase of Y over the increase of X. The increase of Y is 10 because 1 - (-9) = 10. The increase of X is 1 because 5 - 4 = 1. 10 over 1, or 10 / 1, equals 10.

Elenna [48]

Answer:

scalene

Step-by-step explanation:

if a triangle has 3 different sides it's scalene if it has two sides that are the same it's isosceles and if all sides are the same it's an equilateral
