The slope PV is:
m = -4Step-by-step explanation:
Given
P(2, 4)V(3, 0)Determining the slope of PV
(x₁, y₁) = (2, 4)
(x₂, y₂) = (3, 0)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [0 - 4] / [3 - 2]
= -4 / 1
= -4
Thus, the slope PV is:

Bacteria growth. A colony of bacteria is grown under ideal conditions in a laboratory so that the population increases exponentially with time. At the end of 3 h there are 10,000 bacteria. At the end of 5 h there are 40,000 bacteria. How many bacteria were present initially
Answer:
1250 bacteria
Step-by-step explanation:
The formula for Exponential Growth is given as:
P(t)= Poe^rt
Where
P(t) = Population after time t
Po = Initial Population
r = growth rate
t = time
Hence, solving for the above question , we have to find Po
Making Po the subject of the formula
Po = P(t)/e^rt
Step 1
Find the Exponential growth rate
At the end of 3 h there are 10,000 bacteria.
Hence:
Po = 10000/e^3r.... Equation 1
At the end of 5 h there are 40,000 bacteria.
Po = 40000/e^5r..... Equation 2
Equating both equations together,
10000/e^3r = 40000/e^5r
Hence:
e^5r/e^3r = 40000/10000
e^2r = 4
Take the In of both sides
In (e^2r) =In 4
2r= In 4
r = In 4/2
r = In 2
Step 2
Solve for Po(Initial Population)
Using Equation 2
Po = 40000/e^5r..... Equation 2
r = In2
Po = 40000/e^5 × In 2
Po = 40000/2⁵
Po = 1250 bacteria.
Therefore, they was 1250 bacteria initially

Your friend used the proportion 40/100 = 80/? To find 40% of 80 and says that the answer is 200. Complete the explanation as to why your friend is incorrect and find the correct answer.
Answer: See explanation
Step-by-step explanation:
My friends calculation is wrong. 40% of 80 is not 200. It is:
= 40% of 80
= 40/100 × 80
= 0.4 × 80
= 32
He should have represented the missing number by x. Therefore,
40/100 = 80/x
Cross multiply
(40 × x) = (80 × 100)
40x = 8000
x = 8000/40
x = 200

Step-by-step explanation:
A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?
Answer:
31.25 kg of flour is needed to make 50 cakes
Step-by-step explanation:
A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?
We can find it by using unitary method i.e first find quantity of flour needed for 1 cake and then we can find quantity of flour needed for 50 cakes.
Flour needed to make 4 cakes = 2.5 kg
Flour needed to make 1 cake = [tex]\frac{2.5}{4}[/tex] kg
Flour needed to make 50 cakes = [tex]\frac{2.5}{4}\times 50[/tex]
= 31.25 kg
So, 31.25 kg of flour is needed to make 50 cakes

The figure shows ST
intersecting plane A at point V. a right angle. Points P, R, and
Q also lie in the plane.
Which statements are true based on the figure? Select all that apply.
Answer:
A,B,E,F those the answer i have EOC review packet done
Step-by-step explanation:
Points, lines and planes are undefined terms in geometry.
The true statements are:
(c) V lies on line ST(d) ST is perpendicular to plane A(e) ST is perpendicular to RVFirst, we test each option to determine the true and false options.
(a) S, V and U are collinear
Points that are collinear are on the same line
S, V and U are not collinear, because they are not on the same line.
Hence, (a) is false
(b) Q, S, T and U are coplanar
Points that are coplanar are on the same plane
Q, S, T and U are not coplanar, because they are not on the same plane.
Hence, (b) is false
(c) V lies on line ST
Point V is the point of intersection of line ST and plane A
This means that point V lies on line ST and plane A
Hence, (c) is true
(d) ST is perpendicular to plane A
Line ST intersects with plane A at point V at 90 degrees.
Perpendicular lines and planes meet at 90 degrees
Hence, (d) is true
(e) ST is perpendicular to RV
Because line ST intersects with plane A at point V at 90 degrees.
Any line drawn from point V would be perpendicular to line ST
Hence, (e) is true
(f) P, R and Q are collinear
Points that are collinear are on the same line
P, R and Q are not collinear, because they are not on the same line.
Hence, (f) is false

The trainers at Atlantis Aquarium perform shows about sea life. Yesterday, they performed 4 shows in 2 hours. Today, they will perform 6 shows. If they perform shows at the same rate, how many hours will the trainers spend performing shows today?
Answer:
3 hours
Step-by-step explanation:
Number of shows : Time taken
= 4 : 2
Today, they will perform 6 shows.
Number of shows : Time taken
= 6 : x
Equate both ratios to find x
4 : 2 = 6 : x
4/2 = 6/x
Cross product
4 * x = 2 * 6
4x = 12
x = 12/4
x = 3 hours
The trainers will spend 3 hours performing shows today
