Step-by-step explanation:

Answer:

a=6

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

a^2 + 8^2 = 10^2

a^2 + 64= 100

a^2 +64-64 = 100-64

a^2 = 36

Take the square root of each side

sqrt(a^2) = sqrt(36)

a = 6

Answer:

a = 6

Step-by-step explanation:

According to the question,

Using Pythagorean theorem

( a )² + ( b )² = ( c )²

( a )² + ( 8 )² = ( 10 )²

evaluate the exponent

a ² + 64 = 100

subtract 64 from each side

a ² + 64 - 64 = 100 - 64

a ² = 36

Take the square root of each side

√a² = √36

a = 6

Answer:

The area of the shaded region is 240 ft.

Step-by-step explanation:

Area Formula: A = L * H

First, find the area of the WHOLE shape. (300 = 25 * 12)

Next, find the area of the WHITE section. (60 = 5 * 12)

Lastly, subtract the area of the entire shape to the area of the white section. (300 - 60 = 240)

Your final answer should be 240 ft. Hope this helps! :D

Answer:

Part A)

A reasonable domain to plot the growth function is:

[tex]0\leq d \leq 12[/tex]

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:

[tex]f(d)=5(1.02)^d[/tex]

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:

[tex]6.34=5(1.02)^d[/tex]

Divide both sides by five:

[tex](1.02)^d=1.268[/tex]

Take the log of both sides with base 1.02:

[tex]\displaystyle d=\log_{1.02}1.268[/tex]

Using the Change of Base Property, evaluate for d:

[tex]\displaystyle d=\frac{\log 1.268}{\log 1.02}=11.9903...\approx 12[/tex]

So, the biologist concluded her study after 12 days.

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

[tex]0\leq d\leq 12[/tex]

Part 2)

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

[tex]f(0)=5(1.02)^{(0)}=5(1)=5[/tex]

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:

[tex]f(4)=5.4121...\text{ and } f(11)=6.2168...[/tex]

And find the slope between them:

[tex]\displaystyle m=\frac{f(11)-f(4)}{11-4}=0.1149...\approx 0.11[/tex]

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.

Explanation:

A linear pair of angles is where they are both adjacent and supplementary.

Adjacent angles share a common line or ray. In this case, they share ray FE.

Supplementary angles add to 180. So they combine to a straight angle.

Answer:

I am pretty sure it's 495

Step-by-step explanation:

The context of this problem makes me think that the order in which the sites are in does not matter

if that's the case we can solve this using combinations

the combinations formula is as follows:

ACB= [tex]\frac{A!}{(A-B)!*B!}[/tex]

so 12C4= [tex]\frac{12!}{(12-4)!*4!}=495[/tex]

Answer:

So B has the greatest value of slope.

Step-by-step explanation:

A has a negative slope, so A is out.

B, C and D all have positive slopes.

B has a greater slope than C, so C is out.

B has a finite slope, and D has a "slope" of infinite, but much of the time it does not count, because we do not make calculations with infinite slopes, and infinity is not a number (value).

So B has the greatest value of slope.

Use the vertical line test to determine if it is a function

Since a vertical line touches more than one point on the graph, it is not a function

Answer:

33.48

Step-by-step explanation:

Find the diagram attached

Opposite  = 32

Hypotnuse = 58

Sin theta = opposite/hypotenuse

Sin theta = 32/58

Sin theta = 0.5517

theta = arcsin(0.5517)

theta = 33.48

Hence the value of x to the nearest tenth is 33.48

Solution given:

let age of Jailah be x and grandfather's age be y

according to the question

x=¼y-5.....(1)

x=12...........(2)

Now substituting value of x in equation 1

12 =¼y-5

12+5=¼y

17=¼y

doing crisscrossed multiplication

17*4=y

y=68

Jailah’s grandfather is 68 years old.

Answer:

x- 3y -7 =0

Step-by-step explanation:

Point slope form is

y-y1 = m(x-x1)  where m is the slope

y - -2 = 1/3 (x-1)

y+2 = 1/3 (x-1)

Multiply each side by 3 to get rid of the fraction

3y +6 = x-1

Subtract 3x from each side

6 = x-3y -1

Subtract 6 from each side

0=x -3y -7

x- 3y -7 =0

The general form is

Ax +by +C = 0  where A , B C are integers and A > 0

Answer:

x-3y-7=0

Step-by-step explanation:

[tex]y=\frac{1}{3} x+c\\-2=\frac{1}{3}\times 1+c\\c=-\frac{7}{3} \\y=\frac{1}{3} x-\frac{7}{3}\\\\3y=x-7, 0=x-3y-7[/tex]
