(Help please, Subject: Properties of exponents) Organisms A and B start out with the same population size.
Organism A's population doubles every day. After 5 days, the population stops
growing and a virus cuts it in half every day for 3 days.
Organism B's population grows at the same rate but is not infected with the virus.
After 8 days, how much larger is organism B's population than organism A's
population? Answer the questions td find out.
1. By what factor does organism A's population grow in the first five days? Express
your answer as an exponential expression.
Write your answer in the space below.
Answer:
1. 252N = ( x x )N
2. Factor =
Step-by-step explanation:
Let the starting population size for organisms A and B be represented by N.
For organism A;
Day 0: N
Day 1: 2N
Day 2: N
Day 3: N
Day 4: N
Day 5: N
Day 6: N
Day 7: N
Day 8: N
For organism B;
Day 0: N
Day 1: 2N
Day 2: N
Day 3: N
Day 4: N
Day 5: N
Day 6: N
Day 7: N
Day 8: N
1. After the eight days, organism B's population is larger than organism A's population by;
N - N = 256N - 4N
= 252N
= ( x x )N
2. Organism A's population grows by .

Which of the following statements must be true?
A. The measure of angle AGB is greater than the measure of angle ADE.
B. The measure of angle AGB is greater than the measure of angle AED.
C. Segment AE and Segment AB have the same length.
D. The ratio of AG to AE is the same as the ratio of AB to AD.
Answer:
D
Step-by-step explanation:
....iam not sure but i think its a because the other impossible
Answer:
The answer is D.
Step-by-step explanation:
For A- I don't think it's greater, I think they are the same.
For B- I don't think it's greater, I think they are the same.
For C- Segment AE is longer than Segment AB.
So D seems like the more logical answer.

The expression ax²+bx+c is divisible by x-1, has a
remainder of 2 when divided by x+1 and has a remainder of 8 and when divided by x-2 find the values of a, b, and c and
factorise completely.
Answer:
(x - 1)(3x + 2)
Step-by-step explanation:
By the Remainder theorem
Given expression is divisible by x - 1 then f(1) = 0
when divided by (x + 1) then f(- 1) = 2
when divided by x - 2 then f(2) = 8
Substitute x = 1, x = - 1, x = 2 into the expression , that is
a + b + c = 0 → (1)
a - b + c = 2 → (2)
4a + 2b + c = 8 → (3)
Subtract (1) from (2) to eliminate a and c
- 2b = 2 ( divide both sides by - 2 )
b = - 1
Subtract (1) from (3) to eliminate c
3a + b = 8 ← substitute b = - 1
3a - 1 = 8 ( add 1 to both sides )
3a = 9 ( divide both sides by 3 )
a = 3
Substitute a = 3, b = - 1 into (1) and evaluate for c
3 - 1 + c = 0
2 + c = 0 ( subtract 2 from both sides )
c = - 2
Then a = 3, b = - 1, c = - 2
Thus
ax² + bx + c
= 3x² - x - 2
= (x - 1)(3x + 2) ← in factored form
Solve for C.

Answer:
the sum of interior angles of a quadrilateral = 360 degree
Step-by-step explanation:
therefore,
let the angle C be X

314 + X = 360°
X = 360 - 314 = 46°

Answer: 37ft^2
Step-by-step explanation:
Create two separate figures. A full square 3x3 and a rectangle 7x4.
The 7ft line on the right minus 3 ft (because we are cutting out that section of the figure) = 4ft
Area of 3x3 square = 3^2 = 9ft^2
Area of 7x4 rectangle = 7x4 = 28ft^2

3. The trapezoid below contains a square and two right triangles. Find the perimeter of the trapezoid.
Answer:
Perimeter of trapezoid = 25.66 cm
Step-by-step explanation:
Trapezoid ABCD contains two triangles ΔABF, ΔCDE and a square with side length 4 cm.
By applying Pythagoras theorem in ΔABF,
AB² = BF² + AF²
AB² = 4² + 3²
AB = [tex]\sqrt{16+9}[/tex]
AB = 5 cm
Similarly, By applying Pythagoras theorem in ΔCDE,
CD² = DE² + CE²
CD² = 4² + 4²
CD = [tex]\sqrt{32}[/tex]
CD =5.66 cm
Perimeter of the given trapezoid = AB + BC + CD + AD
= 5 + 4 + 5.66 + (3 + 4 + 4)
= 25.66 cm

Find PQ
Answer:
PQ = 29
Step-by-step explanation:
Lengths of the two tangents from a external point to the circle is equal
14x - 13 = 8x + 5 {add 13 to both sides}
14x = 8x + 5 + 13
14x = 8x + 18
14x - 8x = 18
6x = 18
x = 18/6
x = 3
PQ = 14*3 - 13
= 42 - 13
= 29

Which equation represents a line passing through the point (8, 9) with a slope of 3?
The equation of a line passing through the point (8, 9) with a slope of 3 is y = 3x - 15.
What is the equation of a line passing through two given points in 2-dimensional plane?Suppose the given points are [tex](x_1, y_1) and (x_2, y_2),[/tex]
then the equation of the straight line joining both two points is given by
[tex](y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)[/tex]
We have been given a line passing through the point (8, 9) with a slope of 3.
then the equation of the straight line joining both two points is given by
[tex](y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)[/tex]
Its slope would be:
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
m = 3
Therefore, the equation of the straight line
[tex](y - 9) = 3 (x -8)\\\\y - 9 = 3x - 24\\\\y = 3x -15[/tex]
Hence, the equation of a line passing through the point (8, 9) with a slope of 3 is y = 3x - 15.

Answer:

Step-by-step explanation:
A restaurant is making table cloths for their four round tables. Each table is a circle with a radius of 2 ft. Each table cloth needs to be 20% larger than the table surface.
How many whole table cloths can the restaurant get out of a piece of fabric with an area of 64 ft²?
Please help!!
Answer:
4
Step-by-step explanation:
Since it gives us the amount of area of material to use we know we want to find how many times we can divide it into tablecloths. So now we need to find how much each tablecloth is.
so first it tells us that each table has a radius of 2 ft, so we find the area using that. area of a circle is [tex]\pi r^2[/tex] so plugging in 2 ft we get 4π square feet or 12.56.
It also says that each tablecloth needs to be 20% bigger, so we find what 20% larger than 4π is. to do this you do 4pi*1.2 = 4.8π = 15.072 square feet.
Now, how many tablecloths with areas of 15.072 square feet can be made from 64 square feet. Hopefully it's obvious you divide. so 64/15.072 = 4.25
Since we want whole tablecloths and that .25 is a remainder, 4 whole tablecloths can be made.
