Phantasy [73]

Answer:

$14 units$

Step-by-step explanation:

$Solution:-$

$A(5,1)B(7,1)$

$\sqrt{(x_{1}-x_{2} ) ^{2}(y_{2} -y_{1}x^{2} }$

$AB=\sqrt{(7-5)^{2} +(1-1)^{2} }$

$= \sqrt{2^{2} } =2$

$BC=\sqrt{7-7^{2}+(6-1)^{2} }$

$=\sqrt{5^{2} } =5$

$perimeter=2(AB)+2(BC)$

$= 2(2)+2(5)\\$

$= 4+10= 14$

hope it helps...

A biologist is studying the growth of a particular species of algae. She writes the fall inclusion to show the radius of the alg

horrorfan [7]

Answer:

Part A)

A reasonable domain to plot the growth function is:

$0\leq d \leq 12$

Part B)

The y-intercept represents that when the biologist started her study, the radius of the algae was five millimeters.

Part C)

The average rate of change from d = 4 to d = 11 was about 0.11. This means that from the 4th day to the 11th, the radius of the algae grew, on average, at a rate of 0.11 mm per day.

Step-by-step explanation:

The radius of the algae f(d) in millimeters after d days is given by the function:

$f(d)=5(1.02)^d$

Part A)

We know that the radius of the algae was approximately 6.34 mm when the biologist concluded her study. To find the reasonable domain, we can substitute 6.34 for f(d) and solve for d. Therefore:

$6.34=5(1.02)^d$

Divide both sides by five:

$(1.02)^d=1.268$

Take the log of both sides with base 1.02:

$\displaystyle d=\log_{1.02}1.268$

Using the Change of Base Property, evaluate for d:

$\displaystyle d=\frac{\log 1.268}{\log 1.02}=11.9903...\approx 12$

So, the biologist concluded her study after 12 days.

Therefore, a reasonable domain to plot the growth function is:

$0\leq d\leq 12$

Part 2)

The y-intercept of the function is when d = 0. Find the y-intercept:

$f(0)=5(1.02)^{(0)}=5(1)=5$

Since d represent the amount of days after the study had begun, the y-intercept represents the radius of the algae on the initial day.

So, when the biologist started her study, the radius of the algae was five millimeters.

Part 3)

To find the average rate of change for a nonlinear function, we find the slope between the two endpoints on the interval.

We want to find the average rate of change of f(d) from d = 4 to d = 11.

Find the endpoints:

$f(4)=5.4121...\text{ and } f(11)=6.2168...$

And find the slope between them:

$\displaystyle m=\frac{f(11)-f(4)}{11-4}=0.1149...\approx 0.11$

Since f(d) measures millimeters and d measures days, this tells us that, on average, the radius of the algae grew by about 0.11 mm per day from the 4th day to the 11th day.

Find the surface area of polyhedra Pls!! show how you got the surface area

quester [9]

Answer:

52.48

Step-by-step explanation:

find the cross sectional area which is the triangle

triangle = 1/2 x 8.2 x 6.4 = 26.24

then, use the area to multiply by the extended length of 2

26.24 x 2 = 52.48

Lynn is going to cover the floor with tiles.

Vlada [557]

Answer:

Please check explanations

Step-by-step explanation:

Firstly, we calculate the area of the floor

That is the product of the sides

= 300 * 540 = 162,000 cm^2

What is left is to calculate the area of a tile

Since the tile is also rectangular, the area of each tile will be;

60 * 30 = 1,800 cm^2

Since we have both areas, we can now get the number of tiles needed to cover the floor

We can get this by dividing the area of the floor by the area of a tile

This is;

162,000/1,800 = 90

This means that 90 tiles will cover the floor

The cost of a tile

is £4.25

The cost of 90 tiles will be ;

£4.25 * 90 = £382.5

from here, we can see that the £400 is more than £382.5

So we can conclude that she has enough to spend on tiles
