A line has a slope of 1/4.What is a slope parallel to it?What slope is perpendicular?

2 answers:

6 0

A slope parallel to it will have the same slope. So it will be 1/4.

A perpendicular slope will have the opposite reciprocal of the given slope. So it will be -4.

Answer:

The perpendicular slope will be -4.

Step-by-step explanation:

In order to find perpendicular slope, you first need to flip the fraction. So, 1/4 becomes 4/1 or 4. Then you negate it. So, 4 becomes -4.

Five bells begin to ring together and they ring at intervals of 3, 6, 10, 12 and 15 seconds, respectively. How many times will t

Evgen [1.6K]

Answer:

60 times will they ring together at the same second in one hour excluding the one at the end.

Step-by-step explanation:

Given : Five bells begin to ring together and they ring at intervals of 3, 6, 10, 12 and 15 seconds, respectively.

To find : How many times will they ring together at the same second in one hour excluding the one at the end?

Solution :

First we find the LCM of 3, 6, 10, 12 and 15.

2 | 3 6 10 12 15

2 | 3 3 5 6 15

3 | 3 3 5 3 15

5 | 1 1 5 1 5

| 1 1 1 1 1

$LCM(3, 6, 10, 12,15)=2\times 2\times 3\times 5$

$LCM(3, 6, 10, 12,15)=60$

So, the bells will ring together after every 60 seconds i.e. 1 minutes.

i.e. in 1 minute they rand together 1 time.

We know, 1 hour = 60 minutes

So, in 60 minute they rang together 60 times.

Therefore, 60 times will they ring together at the same second in one hour excluding the one at the end.

Use a table of function values to approximate an x-value in which the exponential function exceeds the polynomial function. In y

bekas [8.4K]

F(x) = 2^x; h(x) = x^3 + x + 8

Table

x f(x) = 2^x    h(x) = x^3 + x + 8

0 2^0 = 1 0 + 0 + 8 = 8

1 2^1 = 2    1^3 + 1 + 8 = 10

2 2^2 = 4     2^3 + 2 + 8 = 8 + 2 + 8 = 18

3 2^3 = 8       3^3 + 3 + 8 = 27 + 3 + 8 = 38

4    2^2 = 16    4^3 + 4 + 8 = 76

10    2^10 = 1024 10^3 +10 + 8 = 1018

9    2^9 =   512 9^3 + 9 + 8 = 729 + 9 + 8 = 746

Answer: an approximate value of 10

Can u please solve this question?

Lapatulllka [165]

Answer:

It is TRUE for all Real numbers, i.e. [x] = ]x+1[ for all x∈R.

Step-by-step explanation:

Let's write given statement as [ x ] = ] x+1 [

where [ x ] step function means next integer greater than or equal to x,

and ] y [ means last integer less than or equal to y.

Let's take an example of x = 2.5

So [ 2.5 ] = 3.

and ] 2.5 + 1 [ = ] 3.5 [ = 3.

Similarly, we can take any example of Real numbers like 3.7, 4.2, 5.6, 8.9 etc.

It is TRUE for all Real numbers, i.e. [x] = ]x+1[ for all x∈R.
