In 1996 an outbreak of a disease affected 10 people in a large community. By 1997, the number of those infected had grown to 40. Find an exponential growth function that fits the data.

Answers

Answer 1

Answer: The initial population is 18 and 1 year(t=1) later it is 38

Step-by-step explanation:

38 = 18 * e^(1*k), where k is the growth rate

e^(1*k) = 38/18

Take the natural log(ln) of both sides of the = k = ln(38/18) = 0.747

P(t) = 18 * e^(0.747*t), where P(t) is the population affected at time t(years since 1996)

An 8ft length of 4 inch wide crown molding costs $15. How much will it cost to buy 72 ft of crown molding?

Answers

Answer:

Answer: $70

 

EXPLANATION

 

Step-by-step explanation:

Given, for a 4 inch wide crown molding:

8 ft length costs $14

Cost of 40 ft length = ?

 

8 ft length costs $14

To find the cost of 1 ft length,

Divide through by 8

8ft/8 length costs $14/8

1ft costs $1.75

 

Now, to find the cost of 40 ft length

1ft costs $1.75

1 ft x 40 would cost $1.75

40 ft would cost $70

 

Therefore, it would cost $70 to buy 40 ft of crown molding

Simply the expression by combining the like terms:
-6j + 4 + 2j - 1

Answers

Answer:

-4j + 3 or 3 - 4j

Step-by-step explanation:

you can combine the terms in any order that you want, but i'm going to begin with the j terms.

first, identify the like terms.

-6j + 4 + 2j - 1

then combine the like terms.

-6j + 2j = -4j

now identify the next set of like terms.

-6j + 4 + 2j - 1

combine those like terms.

4 - 1 = 3

after combining the first set of like terms, you're left with: -4j

after combining the second set of like terms, you're left with: 3

therefore the simplified expression is -4j + 3 or 3 - 4j. rearranging those terms doesn't change the answer, so it doesn't matter what order you write it in.

i hope this helps!! have a great rest of your day :)

Which sign makes the statement true? 1 ​

Answers

The sign that makes the statement true is < (less than): 1/3 < 2/3.

What is inequality?

In mathematics, an inequality is a mathematical expression that shows the relationship between two values or quantities, usually indicating which value is greater than, less than, or equal to the other. Inequalities are represented by the symbols < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to). For example, x < y means x is less than y, and x ≥ y means x is greater than or equal to y. Inequalities can also involve variables, and can be solved to find the range of values that make the inequality true.

Here,

The statement 1/3 < 2/3 means that the value of 1/3 is less than the value of 2/3. In other words, when we compare the two fractions, we find that 2/3 is larger than 1/3.

To understand this better, we can think of a whole object (e.g. a pizza) that we want to divide into three equal parts. If we take only one of those parts, that would be represented by the fraction 1/3. On the other hand, if we take two of those equal parts, that would be represented by the fraction 2/3. Therefore, 2/3 is a larger fraction than 1/3, which is why the sign < (less than) makes the statement true.

Answers

Answer:

m∠b = m∠r

Step-by-step explanation:

The triangle was reflected across line m.

A reflection is a rigid transformation. A rigid transformation does not change the measurement or size of a shape, so the pre-image and the image are congruent.

The angles on the pre-image corresponds to the angles on the image. This also is for line segments.

This means (for angle measurements):

Angle A is congruent to Angle P

Angle C is congruent to Angle S

Angle B is congruent to Angle R

Find m∠Z.

Answers

Answer:

m∠Z= 23°

Step-by-step explanation:

if they're equal, as are their angles

124°+33°= 157°

180°-157°= 23°

m∠Z = 23°

The triangles are congruent. Therefore,

ΔXYZ ≅ ΔMNL

∠Y ≅ ∠N

Therefore,

∠Y = 124°

Sum of angles in a triangle = 180°

33 + 124 + m∠Z = 180°

157 +  m∠Z  = 180°

m∠Z = 180 - 157

What is the area of a square?

A square is a four sided quadrilateral with all of the side having equal lengths. The total internal angle of a square is 360° with each side perpendicular to each other.

A square is a 4 sided polygon where all the sides are of equal length.

The area of the square is the square of any one of its side

Let a be the side of the square

Area of the square = a²

Given data ,

Let the area of the square be represented as A

Now , the value of A is

Area of the square = a²

The exact value of the side length of a square with an area of 95 square units can be found by taking the square root of 95.

√95 ≈ 9.74679434481 (approximate value)

  V = πr²h

Here, we have r=2h and V=3000 ft³. Putting these numbers into the formula and solving for h, we get ...

  3000 ft³ = π(2h)²h

  (3000 ft³)/(4π) = h³ . . . . . divide by the coefficient of h³
