Answer: 801.99

Step-by-step explanation:

603 + Percentage increase =

603 + (33% × 603) =

603 + 33% × 603 =

(1 + 33%) × 603 =

(100% + 33%) × 603 =

133% × 603 =

133 ÷ 100 × 603 =

133 × 603 ÷ 100 =

80,199 ÷ 100 =

801.99

Answer:

$801.99

Step-by-step explanation:

You first make 33% into a decimal which makes .33

Then multiply .33 by $603 which equals $198.99

Lastly add $198.99 to $603 and you get $801.99

Answer:

123,456.789

Step-by-step explanation:

The ten thousandth place is less than 5.

Answer:

123,456.789

Explanation:

Given: 123,456.789..........the last 3 digit after decimal place is thousands and 1 digit after decimal place is tenths.

Factorize both sides of the equation:

[tex]\dfrac x{\sqrt{x^2+1}} = x^4 - x[/tex]

[tex]\dfrac x{\sqrt{x^2+1}} = x(x^3-1)[/tex]

[tex]\dfrac x{\sqrt{x^2+1}} - x(x^3-1) = 0[/tex]

[tex]x \left(\dfrac1{\sqrt{x^2+1}} - (x^3 - 1)\right) = 0[/tex]

One immediate solution is then x = 0. This leaves us with

[tex]\dfrac1{\sqrt{x^2+1}} - (x^3 - 1) = 0[/tex]

or as we had earlier,

[tex]\dfrac1{\sqrt{x^2+1}} = x^3 - 1[/tex]

Take the square of both sides:

[tex]\dfrac1{x^2+1} = \left(x^3-1\right)^2[/tex]

[tex]\dfrac1{x^2+1} = x^6 - 2x^3 + 1[/tex]

Turn this into a polynomial equation:

[tex]1 = \left(x^2+1\right) \left(x^6-2x^3+1\right)[/tex]

Expand the right side and make it equal to zero:

[tex]1 = x^8 + x^6 - 2x^5 - 2x^3 + x^2 + 1[/tex]

[tex]0 = x^8 + x^6 - 2x^5 - 2x^3 + x^2[/tex]

Each term in the polynomial has a common factor of x². Factoring this out just gives x = 0 again as a solution.

[tex]0 = x^2 \left(x^6 + x^4 - 2x^3 - 2x + 1\right)[/tex]

[tex]0 = x^6 + x^4 - 2x^3 - 2x + 1[/tex]

You'll need a computer to solve the remain se.xtic equation. Solving over reals, you would find two solutions, x ≈ 0.438 and x ≈ 1.18, but only x ≈ 1.18 is valid.

It stands for :

Solving this question by bodmas rule :

[tex]\begin{gathered}\qquad{\sf{ = 9 + 6( {2}^{2} + 4)}}\\\\\qquad{\sf{ = 9 + 6(2 \times 2 + 4)}}\\\\\qquad{\sf{ = 9 + 6(4 + 4)}}\\\\\qquad{\sf{ = 9 + 6(8)}}\\\\\qquad{\sf{ = 9 + 6 \times 8}}\\\\\qquad{\sf{ = 9 + 48}}\\\\\qquad{\sf{ = 57}}\end{gathered}[/tex]

Answer:

what's the question? it could be both

Answer:

Exponential function: a*b^x

if B is less than 1, it is a decay function

if B is more than 1, then it is a growth function  

if B is 0, then the function neither decreases nor increases

Example 1: 100*0.14^x

The y-intercept is decreasing by 86%

Example 2: 3000*1.14^x

The y-intercept is increasing by 14%

Example 3: 400*0

The y-intercept is neither decreasing nor increasing

Going back to the function, a is the y-intercept, and b is the rate

Answer:

s=10

Step-by-step explanation:

Basically, the range rule-of-thumb is that the range is generally about four times the standard deviation.

First, we find the range:

Range=Maximum-Minimum

Range=100-60

Range=40

Next, divide the range by 4 to get the standard deviation

Range=4(Standard Deviation)

40=4(Standard Deviation)

10=Standard Deviation

Therefore, s=10, which is the standard deviation

Mean:-

Step-by-step explanation:

The average rate of change for the function f(x)= 3^x + 25 using the intervals of x=2 to x=6 is 6.75

The function is given as:

f(x) = 3^x + 25

The interval is given as:

x = 2 to 6

Start by calculating f(2) and f(6)

f(2) = 3^2 + 25 = 34

f(6) = 6^2 + 25 = 61

The average rate of change is then calculated as:

[tex]m = \frac{f(6) - f(2)}{6 -2}[/tex]

This gives

[tex]m = \frac{61 - 34}{6 -2}[/tex]

[tex]m = \frac{27}{4}[/tex]

m = 6.75

Hence, the average rate of change is 6.75

Linear algebra is the study of lines and planes, vector spaces and mappings that are required for linear transforms. It is a relatively young field of study, having initially been formalized in the 1800s in order to find unknowns in systems of linear equations

Answer:

Given :0.2x + 0.3y = 1.3

0.4x + 0.5y = 2.3

To Find solve using substitution method

Solution :

0.2x + 0.3y = 1.3

0.4x + 0.5y = 2.3 -2

Substitute the value of x from 1 in 2

0.4(1.3-0.3) +0.5y = 2.3

y = 3

0.2x + 0.3(3) = 1.3

0.2x = 1.3 0.9

X = 1.3-0.9 0.2

x = 2

So, x = 2 and y = 3

Answer:

[tex]y=5[/tex]

Step-by-step explanation:

Subtract 8 from both sides.

[tex]-1.2y=2-8[/tex]

Subtract 8 from 2 to get -6.

[tex]-1.2y=-6[/tex]

Divide both sides by -1.2.

y= [tex]\frac{-6}{-1.2}[/tex]

Expand [tex]\frac{-6}{-1.2}[/tex] by multiplying both numerator and the denominator by 10.

[tex]y=\frac{-60}{-12}[/tex]

Divide -60 by -12 to get 5.

Answer:

[tex]y=4(4)^x[/tex]

Step-by-step explanation:

Exponential functions are represented in the form [tex]y=a(b)^x[/tex], where a is the initial value and b is the multiplier.

Here, we see that when x = 0, y = 4. This means that 4 is our initial value, or a. You can look at the a variable almost being like the y-intercept of a graph.

Next, we must solve for b. We can do 16 ÷ 4 to find the slope, or multiplier of this function, because 16 is 1 input x-value up from 0. 16 ÷ 4 = 4.

So, we now have all the needed variables, so we plug them into the formula

[tex]y=a(b)^x[/tex]
