Answer:

1 3/7

Step-by-step explanation:

Lay out the two fractions into a problem and then switch 6/15 into 15/6 after that, multiply 4/7 and 6/15, simplify the numbers. Your answer should be 30/21 as a improper fraction. Turn it into a mixed number and it should be 1 3/7

A car was driving for 4 hours and covered 225 miles. A high-speed train is ten times as fast as this car. Find the train's speed

Lubov Fominskaja [6]

Answer:

562.5 mph

Step-by-step explanation:

First, let's find how fast the car is going in miles per hour. We do this by dividing the miles by how many hours it took:

225/4 = 56.25

The car was going 56.25 mph

A high-speed train is ten times faster than this car so you multiply 56.25 by 10

(10)(56.25) = 562.5

The train's speed is 562.5 mph

<em>Hope this helps!</em>

Car is moving on a circle on a plane. At time t (seconds), its x-coordinate is given by x(t) = 10 sin(200t + 3) + 30 while its y

Aleks [24]

Answer:

we have centre of circle as (30,40) and radius = 1

Step-by-step explanation:

Given that a car is moving on a circle on a plane.

At time t (seconds),

$x(t) = 10 sin(200t + 3) + 30$

and

$y(t) = 10 cos(200t + 3) + 40$

$x-30 = 10 sin(200t + 3) \\y-40 = 10 cos(200t + 3) + 40$

when we square and add both the equations we get

$(x-30)^2 + (y-40)^2 = 1$

(since sin square + cos square = 1 always)

i.e. we have centre of circle as (30,40) and radius = 1

The difference quotient of the function that has been presented to us will turn out to be 5.

<h3>How can I calculate the quotient of differences?</h3>

In this step, we wish to determine the difference quotient for the function that was supplied.

To begin, keep in mind that the difference quotient may be calculated by:

Lim h->0 $\frac{f(x+h)-f(x)}{h}$

Now, for the purpose of the function, we need this:

Then we will have:

$\begin{aligned}&\lim _{h \rightarrow 0} \frac{j(x+h)-j(x)}{h} \\&\lim _{h \rightarrow 0} \frac{5 *(x+h)-3-5 * x+3}{h} \\&\lim _{h \rightarrow 0} \frac{5 x+5 h-3-5 x+3}{h} \\&\lim _{h \rightarrow 0} \frac{5 h}{h}=5\end{aligned}$

j(x) = 5x - 3

Then the following will be true:

Therefore, 5 is the value of the difference quotient for j(x) is %
