Answer:

Step-by-step explanation:

a. This is a decay function, since the final value (A) gets smaller and smaller as the days pass by.

b. The bacteria is decreasing by 75% per day exponentially.

c. In order to calculate the amount of bacteria in a week we simply substitute the variable t for 7 (7 days in a week) and solve for A

A = 200(0.75)^7

A = 26.7 bacteria after 1 week

d. In order to calculate this we need to substitute the variable A with 100 and solve for t

100 = 200(0.75)^t   ... divide both side by 200

0.5 = 0.75^t

[tex]\frac{ln(0.5)}{ln(0.75)}[/tex] = t

2.4 = t

It will be half the initial amount after 2.4 days.

The answer is C.) y = 2x + 5

Answer:

[tex]\huge\boxed{\sf tan \ 28 = x / 14}[/tex]

Step-by-step explanation:

Since opposite and adjacent is given, we will use tan as trigonometric ratio.

Hence,

opposite = x , adjacent = 14 and [tex]\theta[/tex] = 28

So,

[tex]\sf tan \theta = opposite / adjacent[/tex]

tan 28 = x / 14

Answer:

Plug the x-values into the equation to get the y values. This will give you coordinates that you can graph a line with.

Step-by-step explanation:

For x = -5:  y = -3 - 2 * (-5) = 7, so the coordinates are (-5, 7)

For x = -2:  y = -3 - 2 * (-2) = 1, so the coordinates are (-2, 1)

(Etc.)

Then, plot these coordinates and draw a line through them to complete the graph.

Step-by-step explanation:

Given

Curve is

[tex]y=x^2-2x-4[/tex]

At the turning point of the curve, the slope will be zero.

Differentiate the curve

[tex]\Rightarrow y'=2x-2[/tex]

Substitute 0 for [tex]y'[/tex]

[tex]\Rightarrow 2x-2=0\\\Rightarrow x=1[/tex]

[tex]\therefore y=1^2-2\times 1-4=-5[/tex]

Answer:

D

Step-by-step explanation:

Here, we want to select the graph of the given exponential function values

Let us take a look at the y-intercept

At the y-intercept, the value of x is 0

The y-intercept for this particular equation is 1

This mean that the y-intercept value is 1

hence, the graph will touch the y-axis at the point y = 1

looking at the graphs , only the graph D provides this, and that should be our answer

Answer:

D (108)

Step-by-step explanation:

I did test

The volume of a square pyramid with a base area of 36 and a height of 9 cm is 108 cm. The correct option is B.

A pyramid is a polyhedron with triangular faces that meet at a common vertex and a polygonal base.

The name of the pyramid is determined by the shape of the base. A pyramid with a square base, for example, is called a square pyramid; a pyramid with a triangular base, a triangular pyramid; and so on.

The formula to find the volume of a square pyramid is given by:

V = (1/3) x base area x height

Substituting the given values, we get:

V = (1/3) x 36 x 9

V = 108

Thus, the correct option is B.

Answer:

x = -5, x = 1.5

Step-by-step explanation:

If the two expressions multiplied together is 0, that means that one of the expressions would have to equal 0. This gives us two possible answers. Our two equations are now:

x + 5 = 0

2x - 3 = 0

We will first solve the first one!

To isolate x, we subtract 5 from both sides to get:

x = -5

Onto the second one!

We begin to isolate x by adding 3 to both sides.

2x = 3

Now we divide both sides by 2.

x = 3/2 or 1.5

Answer:

x = 1

Step-by-step explanation:

[tex]\sqrt[3]{3x - 2} = 1[/tex]        Cube both sides of the equation

3x - 2 = 1

3x = 3

x = 1

Check:  [tex]\sqrt[3]{3(1) - 2} = \sqrt[3]{3 - 2} = \sqrt[3]{1} = 1[/tex]   Since x = 1 makes the original equation true, then x = 1 is the solution.

The correct solution for the given equation is x = 1.

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given is a cubic equation, [tex]\sqrt[3]{3x-2}[/tex] = 1

Solving for x,

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

Cubing both the sides,

([tex]\sqrt[3]{3x-2}[/tex])³ = 1

3x - 2 = 1

3x = 3

x = 1

Hence, the correct solution for the given equation is x = 1.
