Answer:

125600

Step-by-step explanation:

Please specify your answer better next time.

1. If you just want to replace all the "x" with 10, then it would be 403.140100

2. If x is a variable, then 4(10)(3.14)(10)(100)=125,600

What is a logarithms and give atleast two examples of it.

mart [117]

Step-by-step explanation:

Logarithm is basically the exponent - also called power - to which a base must be raised to produce a given number.

Mathematically, it can be displayed as:

$x$ is the logarithm of $n$ to the base $b$ , if $b^{x} = n$ , in which case we write

$x=\log _b\left(n\right)$

Lets take the first example,

$2^{4} = 16$

$x=\log _b\left(n\right)$

Therefore, 4 is the logarithm of 16 to base 2.

Lets take the second example,

$x=\log _2\:64$

$2^x=64$

$x = 6$

Logarithmic functions are basically inverse of exponents.

Here is how they are related to each other:

Logarithm → Exponent

$\log _b\left(n\right)=x\:$ → $n=b^x$

Logarithms are helpful in displaying large number.

−2(x−3)+4>3x−10 solve for x

GalinKa [24]

Answer: x<4

Step-by-step explanation:

−2(x−3) + 4 > 3x − 10

-2x + 6 + 4 > 3x - 10

-2x + 10 > 3x- 10

-5x > -10 - 10

-5x >-20 when divide a negative in an inequality, change the sign.

x< 4

For a certain automobile,

emmasim [6.3K]

Answer:

The answer is

a) 2,128 miles per gallon at 40,36 miles per hour

b) 1,388 miles per gallon at 60 miles per hour

Step-by-step explanation:

Let's find the extreme points of M(x) for 30≤x≤60. M(x) simplified by dividing to 7.8.

$M(x) = -1,92.10^-3x^2+0,155x-1$

To find extreme points we find tangent of M(x) and equal it to 0.

$M'(x) = -3,84.10^-3x+0,155=0$

therefore x= $\frac{-0,155}{-3,84.10^-^3} = 40,36$

This divides our x to 2 different range 30≤x≤40,36 and 40,36≤x≤60

Now we pick a number and investigate from the ranges

30≤x≤40,36 → x = 35 → M'(35) = 0,0206 which is > 0 and that means M is increasing

40,36≤x≤60 → x = 45 → M'(45) = -0,0178 which is < 0 and that means M is decreasing

Next let's look at critical points

x M(x) Before After Decision

30 1,922 - ↑ Local Minimum Point

40,36 2,128 ↑ ↓ Local Maximum Point

60 1,388 ↓ - Local Minimum Point

As we can see (30, 1,922) and (60, 1,388) are local minimum points and (40,36 , 2,128) is the local maximum point.

Since (60 , 1,388) is the lowest local minimum point it is the absolute minimum point and (40,36 , 2,128) is the absolute maximum point.
