Find the greatest common factor of 14, 20, and 25.

Answers

Answer 1
Answer: 14=2                       20=2                            25=5
 7=7                        10=2                              5=5  
 1=1                         5=5                               1=1        
so the one for 14     1=1                                so the answer for 25
would be 2*7           so the answer for 20      would be 5*5
                                would be 2*2*5 or 4*5

the reason that i did not put the one into the math problems is because anything times one is its self so i hope that this helps

What are the period and amplitude of the function?A) period 3, amplitude 1.5
B) period 3, amplitude 3
C) period 4, amplitude 1.5
D) period 4, amplitude 3

Answers

Answer:

Option: A is the correct answer.

      A)  Period: 3 , amplitude : 1.5

Step-by-step explanation:

We know that Period of a function is the smallest value such that the function repeats after a fixed time.

and also the amplitude of the function is the height above or below the mid-line.

After looking at the graph we see that the period of the function is: 3

Since the function is repeating itself after every x=3.

Also, the mid-line of the function is: y= -0.5.

Hence, the height above the mid-line is: 1+0.5 = 1.5

        Hence, amplitude= 1.5

period 3, amplitude 1.5

How do you solve 4x^2-12x=7 algebraically

Answers

(if you don't wanna read all this the answer is at the bottom btw)

move the 7 over to equate the equation to 0

4x^2 - 12x -7 = 0

(ok now you have a (4), b (-12), and c (-7) here you can either use the quadratic formula to solve it or factor the equation)

to factor it, you have to multiply a and c (4*-7 = -28) and find two numbers that multiply to -28 and add to -12

the numbers are -14 and 2. sub those into the equation in place of b

4x^2 + 2x - 14x - 7 = 0

find the lcd of the first two terms and the last two terms to factor them

2x(2x + 1) - 7(2x+1) = 0
(2x -7) (2x+1) = 0
(x-7/2)(x+1/2) = 0

to find the two x values you need to find what values make the equation equal 0 on both sides.

so x is 7/2 or -1/2

The amount of time needed to complete a certain road trip, t, varies inversely with the speed of avehicle, s. At a speed of 68 miles per hour, the trip will be complete in 15 hours. What would the
speed of the car have to be to complete the trip in 17 hours?

Answers

The speed of car must be 60mile/hour, so that the trip will complete in 17 hours.

What is speed?

The rate of change of position of an object in any direction is called speed.

How do you calculate speed when distance and time is given?

speed = (distance)/(time)

According to the given question

At a speed of 68 miles per hour, the trip will be complete in 15 hours.

⇒ Total distance covered in 15 hours = 68 × 15 = 1,020 miles  

( because, distance = speed × time)

Therefore, the speed of car to complete the trip in 17 hours

= (1020)/(17) =60miles/hr

Hence, the speed of car must be 60mile/hour, so that the trip will complete in 17 hours.

Answer:

x = 60

Step-by-step explanation:

t = (k)/(x)

15 = k/68

k=1020

~~~~~~~~~~~

17 = 1020/x

x = 1020/17

x = 60
