Mathematics
1 answer:
lbvjy [14]3 years ago
7 0

Answer:

x=-1

Step-by-step explanation:

-3+75x<-75+3x

75x-3<-75+3x

75x-3<3x-7575x−3<3x−75

75x-3-3x<-75

72x-3<-75

72x<-75+3

72x<-72

x=-1

A student wanted to find the sum of all the even numbers from 1 to 100. He said:
murzikaleks [220]

Answer:

The statements are incorrect as: The sum of even numbers from 1 to 100(i.e. 2550) is not double\twice of the sum of odd numbers from 1 to 100(i.e. 2500).

Step-by-step explanation:

We know that sum of an Arithmetic Progression(A.P.) is given by:

where 'n' denotes the "number" of digits whose sum is to be determined, 'a' denotes the first digit of the series and '' denote last digit of the series.

Now the sum of even numbers i.e. 2+4+6+8+....+100 is given by the use of sum of the arithmetic progression since the series is an A.P. with a common difference of 2.

image with explanation

Hence, sum of even numbers from 1 to 100 is 2550.

Also the series of odd numbers is an A.P. with a common difference of 2.

sum of odd numbers from 1 to 100 is given by: 1+3+5+....+99

.

Hence, the sum of all the odd numbers from 1 to 100 is 2500.

Clearly the sum of even numbers from 1 to 100(i.e. 2550) is not double of the sum of odd numbers from 1 to 100(i.e. 2500).

Hence the statement is incorrect.

The mean of four numbers is 6. Three of them are 3.4,10.7and 7.8. what is the fourth number?​
Marianna [84]

Answer:

2.1

Step-by-step explanation:

Use the equation

Sum of elements = average x number of elements

sum = (6)(4)

sum = 24

Add up the numbers we know: 3.4 + 10.7 + 7.8 = 21.9

24 - 21.9 = 2.1

This means the fourth number is 2.1

How to do this?
Mandarinka [93]
This equation uses two properties of logarithms:

\ln(g^x) = x \ln(g)

\ln(a) + \ln(b) = \ln(ab)

So you could take the ln from left and right hand side in the equation, and get:

(2-x)ln 3 = x ln 5

then

2 ln 3 - x ln 3 - x ln 5 = 0 =>

x(ln 3 + ln 5) = 2 ln 3

so x = 2 ln 3 / (ln3 + ln5)

Now using the 1st property you can say 2 ln 3 is ln 3² = ln9
and using the 2nd property you can say ln3 + ln5 = ln15

so x= ln9 / ln15

Vector v has a direction of (5,3) find the direction angle for v to the nearest degree
Vesnalui [34]

Answer:

31^{\circ}

Step-by-step explanation:

We have been given that vector v has a direction of (5,3). We are asked to find direction angle for v to nearest degree.

We know that direction of vector with components (a,b) can be determined by \theta=\text{tan}^{-1}(\frac{b}{a}).

Upon substituting the components of given vector in above formula, we will get:

\theta=\text{tan}^{-1}(\frac{3}{5})

\theta=30.9637565^{\circ}

Upon rounding to nearest degree, we will get:

\theta\approx 31^{\circ}

Therefore, the direction angle for vector v is 31 degrees.
