What does the figurative language in this

sentence suggest about the narrator?

He feels that people should have used better tools

to help them detect advanced life forms on other

planets.

He sympathizes with people for not apprehending

that there was advanced life on other planets.

He is unable to believe that there could be any

form of life more advanced than humans.

Answer: 13.89 in ==> B

Step-by-step explanation:

A=area of rectangle, l=length, w=width

A=l*w

108.35=7.8*w

108.35/7.8=7.8w/7.8

w=108.35/7.8

w=13.891 ==> w=13.89 in==> B

In linear equation, there was 235 jars with 0.5 kg almond and 276 jars with 0.25 kg almonds.

What are a definition and an example of a linear equation?

Let the number of 250g=0.25  kg jars be x and that of 500g=0.5 kg jams be y;

therefore:

total number of jars was

x+y=511

x=511-y..........i

total amount kg was:

0.25x+0.5y=186.5....ii

substituting i in ii

0.25(511-y)+0.5y=186.5

127.75-0.25y+0.5y=186.5

solving for y we get:

0.25y=186.5-127.75

0.25y=58.75

y=58.75/0.25

y=235 jars

and

x=511-x

=511-235

=276

hence , there was 235 jars with 0.5 kg almond and 276 jars with 0.25 kg almonds.

Answer:

Typically when solving an equation with one variable, your objective is to isolate the variable on one side of the equation. This can be done adding/subtracting number to cancel them out on one side. You can also multiply/divide coefficients in order to isolate a variable.

Example:

Add -4 to both sides to isolate the variable.

Simplify.

Divide both sides by 2 to isolate the variable on one side.

Step-by-step explanation:

we get f(-4)= -52 and f(3)=4

suppose f(x)= -2x^2+6x+4

we have to compute f( -4)  and  f(3)

The value of f(-4) is found by substituting -4 into the equation per variable, solving and simplifying as needed, to get the answer.

f(x)= -2x^2+6x+4

we have to compute f( -4)  

then f( -4)= -2(-4)^2+6(-4) +4

               = -32-24+4

               = -52

similarly ,The value of f(3) is found by substituting 3 into the equation per variable, solving and simplifying as needed, to get the answer.

f(x)= -2x^2+6x+4

we have to compute f( 3)  

then f( 3)= -2(3)^2+6(3) +4

               = -18+18+4

               =4

Hence we get f(-4)= -52 and f(3)=4

Each logarithm as the quotient of two common logarithms is :

[tex]\frac{log\\ 8}{log \\3}[/tex]

In, mathematics a logarithmic equation is inverse of exponential equation. That means, we can easily convert the logarithmic equation into exponential equation and vice versa. The basic form of the logarithm function can be written as  .

   [tex]log_ax=N[/tex]

where, a is the base of function or equation

           x define expression

Mathematically, if  [tex]a^N=x[/tex]  is an exponential function then, this can be converted to logarithmic function as  [tex]log_ax=N[/tex].

There are many formulas that are given to us for solving several simple and complex problems based on logarithmic functions and logarithmic equations.

Answer:

  (x +3)² +(y -4)² = 9

Step-by-step explanation:

You want the equation of a circle with center (-3, 4) and radius 3.

The equation of a circle with center (h, k) and radius r is ...

  (x -h)² +(y -k)² = r²

You have a circle with center (h, k) = (-3, 4) and radius r = 3. Using these values in the above equation, we find the circle equation to be ...

  (x -(-3))² +(y -4)² = 3²

  (x +3)² +(y -4)² = 9

According to the box-and-whisker plot,

5)The 25th quartile = 60

6)The 75th quartile = 100

7)The range = 40

Box-and-whisker plot allows us to determine the mean, the largest or the lowest number in the data set as well as the quartiles in the data.

In this case, from the given figure,

Median is equal to = 80,

The range is equal to = 110-40

We can subtract the value,

So we can write,

The range is equal to = 70.

The 25th quartile is equal to = 60

The 75th quartile is equal to = 100.

The range is equal to = 100-60

We can subtract the value,

So we can write,

The range is equal to = 40. 

So,

Then,

The median=80

The range=70

Therefore,

According to the box-and-whisker plot,

The value of the function f(x) + 1 is 3x + 3

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The functions are given as

f(x) = 3x + 2

g(x) =x^2 - x

To calculate the value of the function f(x) + 1, we use the following definitions:

New function = f(x) + 1

Substitute f(x) = 3x + 2 in New function = f(x) + 1

So, we have

New function = 3x + 2 + 1

Evaluate the sum

So, we have

New function = 3x + 3

Rewrite as

So, we have

f(x) + 1 = 3x + 3

Hence, the value of the function f(x) + 1 is 3x + 3

The situation in which a function behaves differently over different parts of its domain is modeled by considering it to be a piecewise function.

What is Mathematical function ?

Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable

Such a situation can be explained through an example:

f(x) =   { x, for x > 0

        {     1, for x = 0

        { -x, for x < 0

now, when we take x value less than 0, say x= -1

   thus, f(x)= f(-1)= -(-1) = 1 , here we used f(x) given x<0

now, when we take x value more than 0, say x= 1

   thus, f(x)= f(1)= (1) = 1, here we used f(x) given x>0

now, when we take x =  0,

   thus, f(x)= f(0)= 1, here we used f(x) given x=0

this is how we model piecewise function, we  use f(x) as per the value of x. Following image shows plotted answer for this example.

Since inequalities given are exclusive of 0, we leave the dot at the origin unfilled. Now, for x = 0. Since the value is constant at f(x) =1, we pointed a point at (0,1)

=log (7/t²)^1/s

The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number.

Based on the logarithm base, the logarithmic functions are broadly divided into two types. There are common and natural logarithms. Common logarithms are based on the number 10, while natural logarithms are based on the base "e." The power to which a number must be raised in order to obtain another number is known as a logarithm (see Section 3 of this Math Review for more about exponents).

= x² + 8x + 3x + 24

= x² +11x + 24

Let us now test the equivalency .

(x+8) (x+3) = (1+8)(1+3) = (9)(4) = 36

x² +11x + 24 = (1)² + 11(1) + 24 = 36
