Step-by-step explanation:

It represents the initial number of bacteria to start with. It can represent nothing else.

Step-by-step explanation:

Y is directly proportional to X" can be rewritten as a mathematical expression of the form Y = KX

"K" is the constant of proportionality and must be determined from the initial information.

If Y = 45 when X=140 means 45 = 140K

K = 45/140 = 0.32

Now that we know the value of K, we can use it to calculate the value of Y when X=70

Y = (0.32)(70) = 22.4

Your Answer is 11 inches by 2 inches

Step-by-step explanation:

Area of Rectangle: Area = Length * Width

Given information:

Put that into the Formula.

Area = Length * Width

22 in^2 = (2x - 1) * (x - 4)

Solve.

22 in^2 = (2x - 1) * (x - 4)

[tex]22 = (2x^2 - 9x + 4)\\2x^2 - 9x - 18 = 0[/tex]

Factor it.

(2x^2 - 9x - 18) = 0

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

[tex]x=-\frac{3}{2} ,6[/tex]

Plug that into the Length and Width to find the actually Length and Width.

Length:

[tex]2x - 1\\2*-\frac{3}{2}-1\\ -3-1\\-4\\[/tex]

Width:

[tex]x - 4\\-\frac{3}{2}-4\\ -\frac{11}{2}[/tex]

Area = Length * Width

Area = - 4* -11/2

Area = 22

Length:

[tex]2x - 1\\2*6-1\\ 12-1\\11\\[/tex]

Width:

[tex]x- 4\\6-4\\ 2[/tex]

Area = Length * Width

Area = 11 * 2

Area = 22 in^2

Answer:

The equation of the line in point-slope form is y - 2 = -4(x + 5).

Step-by-step explanation:

Use the point-slope equation: [tex]y-y_1=m(x-x_1)[/tex].

Substitute the point (-5, 2) and the slope m = -4 into the equation.

If we stop here, this is the equation of the line in point-slope form.

If  the confidence interval is 95%, the maximum number of employees who could have agreed is about  is 144.

First step

Confidence interval=(Population±Margin of error)

Confidence interval=(0.65±0.0675)

Confidence interval=(0.65-0.0675); (0.65+0.0675)

Confidence interval=0.5825; 0.7175

Second step

Maximum number= 0.7175×200

Maximum number=143.5

Maximum number=144 (Approximately)

A statistical question Len could ask is "How tall is a red kangaroo?"

Step-by-step explanation:

A statistical question is something that we can ask and test hypotheses about using collected data. There will not be a specific answer, but rather multiple answers and we can average them in a sampling distribution.

Let's examine each question:

"How tall is a red kangaroo?"

"Are there red kangaroos in Asia?"

"Are red kangaroos an endangered species?"

What is the tallest red kangaroo ever recorded?"

Answer: Choice C

7*r+7*4-3

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

Reason:

We use the distributive property to go from 7(r+4) to 7*r+7*4

Multiply the outer 7 by each term inside.

Then the -3 tags along without any changes to it

So we go from 7(r+4) - 3 to 7*r+7*4 - 3

This can be simplified further to 7r+25, but your teacher has chosen not to simplify at this time.

The area of the smallest circle with radius 3 is 28.27 unit². The area of the yellow ring and white ring is 28.27 unit² and 56.55 unit².

The area of the circle is the space occupied by it. It can be given as,

[tex]A=\pi r^2[/tex]

Here (r) is the radius of the circle.

In this diagram, three concentric circles' rectangle.

The radius of the smallest circle is 3.

[tex]r_1=3\rm\unit[/tex]

Thus, the area of it is,

[tex]A=\pi (3)^2\\A=28.27\rm\; unit^2[/tex]

Let suppose the mid-point of the rectangle is D. Here, OB is the diagonal of the rectangle in which,

[tex]OD=BD[/tex]  

The radius of the yellow ring's outer face from point O is,

[tex]r_3=OD+BD\\r_3=OD+OD\\r_3=2OD\\[/tex]

OD is the radius of the small circle, which is 3 units long. Thus,

[tex]r_3=2\times3\\r_3=6\rm\; units[/tex]

The line segment OC is the radius of the white circle from point O. In the triangle COB from the Pythagoras theorem, the radius r₂ of the middle circle is,

[tex]r_2=\sqrt{r_3^2-r_1^2}\\r_2=\sqrt{6^2-3^2}\\r_2=3\sqrt3[/tex]

Thus, the area of the yellow ring is,

[tex]A_y=\pi r_3^2-\pi r_2^2\\A_y=\pi (6)^2-\pi (3\sqrt{3})^2\\A_y=28.27\rm\; unit^2[/tex]

The area of white ring is,

[tex]A_w=\pi r_2^2-\pi r_1^2\\A_w=\pi (3\sqrt{3})^2-\pi (3)^2\\A_w=56.55\rm\; unit^2[/tex]

Hence, the area of the smallest circle with radius 3 is 28.27 unit². The area of the yellow ring and white ring is 28.27 unit² and 56.55 unit².

Step-by-step explanation:

The intersection is when both functions have same coordinates

Substitute to get

The y- coordinate is

So the intersection point is (1, 14)

Answer:

(1, 14)

Step-by-step explanation:

Given functions:

[tex]\begin{cases}f(x)=-2x+16\\g(x)=4x+10\end{cases}[/tex]

Substitute the function notation for y to create a system of equations:

[tex]\begin{cases}y=-2x+16\\y=4x+10\end{cases}[/tex]

To find the points of intersection of the given functions, solve the system of equations.

Multiply the first equation (function f(x)) by 2:

[tex]\implies 2y=-4x+32[/tex]

Add this to the second equation (function g(x)) to eliminate x:

[tex]\begin{array}{r l}4x+10 & = y\\+ \quad -4x+32 & = 2y\\\cline{1-2} 42 & = 3y\end{array}[/tex]

Solve for y:

[tex]\implies 3y=42[/tex]

[tex]\implies y=14[/tex]

Substitute the found value of y into one of the equations and solve for x:

[tex]\implies 4x+10=14[/tex]

[tex]\implies 4x=4[/tex]

[tex]\implies x=1[/tex]

Therefore, the point of intersection of the given functions is (1, 14).

Answer:

112 degrees

Step-by-step explanation:

180-68=112

Since they are supplementary they form a straight angle, or 180 degrees so the angle AED is 112

Answer:

112

Step-by-step explanation:

∠AED and 68 are Linear pair angles.

That is their sum will be equal to 180,

∠AED + 68 = 180

∠AED = 180 - 68

∠AED = 112

Step-by-step explanation:

the area (A) of the shaded region is calculated as

A = area of outer triangle - area of inner triangle

  = [tex]\frac{1}{2}[/tex] bh - [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

  = [tex]\frac{1}{2}[/tex] × 13 × 14 - [tex]\frac{1}{2}[/tex] × 8 × 8

Solution: x = 5; The slope is undefined.

The slope that is perpendicular to the x-axis is undefined.

Explanation:

Given point: (5,2)

Since the line is perpendicular to the x-axis, then, the line is vertical.

Hence, x = 5

Answer:

x = 5, the slope is undefined

Step-by-step explanation:

Hello!

To be perpendicular to the x-axis, the line has to intersect at a 90° angle, causing it to be a vertical line with an undefined slope.

This removes the two middle options, as they have a slope of 0.

Consequently, looking at the two options, y=2, and x=5, y=2 would give us a parallel line to the x-axis, as we are drawing a line through all points with a y-coordinate of 2.

The correct option is x=5.
