Answer: (-2)

Step-by-step explanation: The international standard symbol for inch is in (see ISO 31-1, Annex A) but traditionally the distance is denoted by a double prime, which is often approximated by double quotes, and the foot by a prime, which is often approximated by an apostrophe. For example, three feet two inches can be written as 3′ 2″. Symbol: in or ″ (the double prime)

A moose population is growing exponentially following the pattern in the table shown below. Assuming that the pattern continues,

EleoNora [17]

Answer:

7,692 moose.

Explanation:

The table that shows the pattern for this question is:

Time (year) Population

0 40

1 62

2 96

3 149

4 231

A growing exponentially pattern may be modeled by a function of the form P(x) = P₀(r)ˣ.

Where P₀ represents the initial population (year = 0), r represents the multiplicative growing rate, and P(x0 represents the population at the year x.

Thus you must find both P₀ and r.

1) P₀ 

Using the first term of the sequence (0, 40) you get:

P(0) = 40 = P₀ (r)⁰ = P₀ (1) = P₀

Then, P₀ = 40

2) r

Take two consecutive terms of the sequence:

P(0) = 40 r⁰ = 40

P(1) = 40 r¹ = 40r = 62

P(1) / P(0) = 40r / 40 = 62/40

r = 62/40 = 1.55

You can verify that, for any other two consecutive terms you get the same result: 96/62 ≈ 149/96 ≈ 231/149 ≈ 1.55

3) Model

Thus, your model is P(x) = 40(1.55)ˣ

 4) Population of moose after 12 years

P(12) = 40 (1.55)¹² ≈ 7,692.019 ≈ 7,692, which is round to the nearest whole number.

A rectangle flower bed is 9 feet wide and 12 feet long .what is the length of the diagonal?

BigorU [14]

Answer:

15 feet

Step-by-step explanation:

The question talks about;

A rectangular flower bed whose dimensions are 12 ft by 9 ft

We are required to determine the length of the diagonal

To answer the question, we need to know the following;

All the angles in a rectangle are right angles
A diagonal divides a rectangle into two right-angled triangles
The dimensions of the rectangle acts as the legs of right angled triangle.

Therefore;

Using Pythagoras theorem;

a² + b² = c²

Where, c is the hypotenuse (in this case the diagonal)

a and b are the shorter sides of the right-angled triangle

Therefore;

c² = 12² + 9²

c² = 144 + 81

= 225

c = √225

= 15

Therefore, the length of the diagonal is 15 feet

Aliun [14]

Answer:

Step-by-step explanation:

So, this is a percentage problem.

Start off by finding how many students 0.28% is:

If 100% = 5780

0.01% = 0.578

Now:

0.01% = 0.578

0.28% = 16.184

The exercise tells you to round for a whole person, so 16.184 turns 17

And that's the answer!

What is the perimeter of the trapezoid graphed below?

Zanzabum

To get the perimeter of the trapezoid, we will add the lengths of the 4 sides together.
So, first we will need to get the length of each side.

Base of trapezoid = 8 - 2 = 4 units
The upper edge of the trapezoid = 6 - 4 = 2 units

Now, for the two side edges, we can note that they are both equal. So, we need to get only one length (as the other would be the same). I will get the length of the left side.
Coordinates of the start point are (2,4) which represent (x1,y1)
Coordinates of the end point are (4,9) which represent (x2,y2)
To get the distance between the two points, we will use the rule attached in the image below as follows:
distance = sqrt ((4-2)^2+(9-4)^2)
distance = √29
Therefore, each of the side edges equal √29 units

From the above, we can now easily get the perimeter as follows:
perimeter = 6 + 2 + √29 + √29
perimeter = 8 + 2√29 units

Based on the above calculations, the best choice would be:
D. 8 + 2√29 units
