Susan drove to visit a friend. She drove 345

padilas [110]

Answer:

$Average\ Speed = 60 mi/hr$

Step-by-step explanation:

Given

$Distance = 345\ miles$

$Time = 5\ hours\ 45\ minutes$

Required

Determine the average speed

This is calculated as thus:

$Average\ Speed = \frac{Distance}{Time}$

Convert time to hour:

$Time = 5\ hours\ 45\ minutes$

$Time = 5\ hours + \frac{45}{60}\ hour$

$Time = 5\ hours + \frac{3}{4}\ hour$

$Time = \frac{20 + 3}{4}\ hours$

$Time = \frac{23}{4}\ hours$

$Time = 5.75\ hours$

$Average\ Speed = \frac{Distance}{Time}$

$Average\ Speed = \frac{345}{5.75}$

$Average\ Speed = 60 mi/hr$

The parabola y=x2y=x^2 y=x 2 y, equals, x, squared is scaled vertically by a factor of 110\dfrac{1}{10} 10 1 start fraction, 1

sweet [91]

Question is not well presented

The parabola y=x² is scaled vertically by a factor of 1/10.

What is the equation of the new parabola?

Answer:

The equation of the new parabola is 0.1x²

Step-by-step explanation:

Given

Parabola: y = x²

Scale = 1/10 = 0.1

The interpretation of this question is that; there's a need to scale the graph in ratio 1:10.

I.e; 1 unit on the parabola is being represented by 10 unit on the scale

So, x (on the new parabola) = 1/10 of old x.

So, the new equation of the parabola = 1/10x²

New equation = 0.1x²

Hence, the equation of the new parabola is calculated as 0.1x²

Identify the variation as direct, inverse, joint or combined. A = r²

myrzilka [38]

Answer : Direct Variation

Question :

Identify the variation as direct, inverse, joint or combined. A = $\pi r^2$

We know direct variation is y = kx

Where k is the constant of proportionality

When value of x increases then y also increases. when x value decreases then y value decreases.

The value of y depends on value of x It means y is directly proportional to x.

Hence A = $\pi r^2$ is a direct variation.
