If a bicyclist is traveling at a speed of 10 km/h, he will be late by 1 hour. If he will travel at a speed of 15 km/h, then he w

Svetllana [295]

Answer:

The speed should he travel to arrive on time is 12 km/h

Step-by-step explanation:

Given as :

Let the time taken by bicyclist = T h

If bicyclist travel with speed 10 km/h,

Then the time taken by him = ( T + 1 ) hours

Again

If bicyclist travel with speed 15 km/h ,

Then the time taken by him = ( T - 1 ) hours

Now Let The distance cover by bicyclist = D km = Speed × Time

So, As The distance cover is same for both case

∴ 10 × (T + 1 ) = 15 × (T - 1)

Or, 2 × (T + 1 ) = 3 × (T - 1)

Or, 2 T + 2 = 3 T - 3

Or, 3 +2 = 3 T - 2 T

∴ T = 5 hour

So, Distance cover by bicyclist = D = 10 × (5 + 1 )

Or, D = 60 km

So, new speed of bicyclist with time 5 hour and distance cover 60 km

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

Or, New Speed = $\frac{60}{5}$

∴ New Speed = 12 km/h

Hence The speed should he travel to arrive on time is 12 km/h Answer

verify that the fucntion satisfies the three hypotheses of rolles theorem on the given interval . then find all numbers c that s

Ghella [55]

The roots of the polynomial x^3 − 2x^2 − 4x + 2 are:

x1 = 0.42801

x2 = −1.51414

x3 = 3.08613

x1 and x2 are in the desired interval [-2, 2]

f'(x) = 3x^2 - 4x - 4

so we have:

3x^2 - 4x - 4 = 0

x = ( 4 +- √(16 + 48) )/6

x_1 = -4/6 = -0.66

x_ 2 = 2

According to Rolle's theorem, we have one point in between:

x1 = 0.42801 and x2 = −1.51414

where f'(x) = 0, and that is x_1 = -0.66

so we see that Rolle's theorem holds in our function.

(FIRST PERSON TO ANSWER GETS BRAINLIEST!!!) A student earned $2500.75 at his summer job making $12.50 per hour. Let h represent

laiz [17]

Answer:

$12.50 \space\ h = 2500.75$

Step-by-step explanation:

We know from the question that the student earned $12.50 per hour.

Using this information, we can say that if the student worked for h hours, they would make a total of 12.50 × h dollars.

We also know that the total money they earned is $2500.75.

∴ Therefore, we can set up the following equation:

$\boxed {12.50 \times h = 2500.75}$

From here, if we want to, we can find the number of hours worked by simply making h the subject of the equation and evaluating:

h = $\frac{2500.75}{12.50}$

= 200.6 hours
