Number 5 please I’m having trouble

Using exponential function concepts, it is found that it represents a decay of 19.4%.

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

In this problem, the function is:

[tex]A(x) = 5800(0.806)^x[/tex]

Since the rate of change is less than 1, it is a decay.

Then:

1 - r = 0.806.

r = 1 - 0.806 = 0.194.

The function represents a decay of 19.4%.

Answer:

25%

Step-by-step explanation:

find the differences between original price $4000 and the altered price $5000.

$5000 - $4000 = $1000

to find the tax percent charged, take the difference price, divide by the original price and multiply with 100, ( to find percentage, it is a must to multiply with 100 ).

1000/4000 x 100

= 25%

so you will get 25 %

Answer:

A) [tex]9 *l=54[/tex]

Step-by-step explanation:

The area of a rectangle is w*l=A, where w is the width and l is the length.

In this question, we are given 2 of the variables. We are told that the width is 9 and the area is 54. So, to find the equation that represents this situation, simply plug in the values.

Then, if needed we can find the length of the rectangle. Through the division property of equality, we know that dividing both sides of the equation maintains the equality of the equation. So, we can divide both sides by 9 to isolate the variable.

The slope is -7/2

Y = mx + b

m stands for the slope (numerical coefficient for x)

Answer:

1100 milliliters.

Step-by-step explanation:

First, separate the numbers 275, it will be 200, 70, and 5.

Second, multiply 4x200, it equals 800

Third, multiply 4x70, it equals 280

Fourth, multiply 4x5, it equals 20.

Fifth, add them all together one by one like 280+20=300, then add 280+800 which is 1100.

Given the following functions expressed as:
[tex]Y = - (x - 5)^2 + 3 \\y = -3(x - 6)^2 + x + 1[/tex]

Equating both expression will give

-(x-5)² + 3 = -3(x-6)² + x + 1

-(x-5)²  +3(x-6)² + 3 - x - 1 = 0
-(x-5)²  +3(x-6)² + 2 - x = 0

-(x² - 10x + 25) + 3(x²-12x + 36) + 2 - x = 0

x² + 10x - 25 + 3x² +36x + 108 + 2 - x = 0

4x² + 45x + 85 = 0

Factorize for the value of x

On factorizing, the value of x is 2.405

Function 1 and the slope is -4/7

=================================================

Explanation:

The slope of y = mx+b is m, which is the number to the left of x.

For function 1

y = (-4/7)x - 4

the slope here is m = -4/7 = -0.57 approximately

Let's use the slope formula to find the slope of function 2 given by the table of values.

Pick any two rows from that table. I'll pick the first two rows.

m = (y2-y1)/(x2 - x1)

m = (0.8 - 2)/(2 - 0)

m = -0.60

Comparing -0.57 and -0.60, we see that -0.57 is closer to zero on the number line. Meaning that function 1 has the less steep slope (i.e. more shallow slope). The further you go away from zero on the number line, in either direction, the slope will get steeper.

The domain of the provide function where the function is defined is x less than the number three.

Domain of a function is the set of all the possible input values which are valid for that function.

The function given in the problem is,

[tex]y=\ln\left(\dfrac{-x+3}{1}\right)[/tex]

The above function is the function of logarithm. For the logarithmic function, it is defined for all the real numbers except 0.

Thus, the function should be greater than zero as,

[tex]\left(\dfrac{-x+3}{1}\right) > 0\\(-x+3) > 0\\-x > -3[/tex]

Change the sign of both side, by changing the inequality,

[tex]x < 3[/tex]

Thus, the domain of the provide function where the function is defined is x less than the number three.
