(72-61-2)-(572-31+4)

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

3*10=30

40+30=70

Answer:

70

Step-by-step explanation:

First find the area of the bottom rectangle

13 -10 = 3

A = 3*10 = 30

Then find the area of the top rectangle

A = 10 *4 = 40

Add the areas together

30+40= 70

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.

Answer:

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.

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:

Let M = Maggie's age

B = Brother's age

Then  M + B = 32

B = 2M - 7        

Then   M + 2M - 7 = 32

3M= 39 = 13

M= 13

Maggie is 13.

1040 litros de leche

Step-by-step explanation:

65 x 16 =1040

The cow will give 260 liters of milk in 16 days.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have a cow that gives 65 liters of milk in 4 days.

Assume that it gives [x] liters of milk in 16 days.

Now, in 4 days, it gives 65 liters of milk.

Then, in 1 day she would give (65/4) liters of milk.

Then, in 16 days -

x/16 = 65/4

x = (65 x 16)/4

x = 65 x 4

x = 260 liters

Therefore, the cow will give 260 liters of milk in 16 days.

Refer to the question statement translated into english below -

A cow gives 65 liters of milk in 4 days, how many liters should it give in 16 days? If its production is constant.

Refer to the solution in the Spanish language below -

Tenemos una vaca que da 65 litros de leche en 4 días.

Suponga que da [x] litros de leche en 16 días.

Ahora, en 4 días da 65 litros de leche.

Luego, en 1 día daría (65/4) litros de leche.

Luego, en 16 días -

x/16 = 65/4

x = (65 x 16)/4

x = 65 x 4

x = 260 litros

Por tanto, la vaca dará 260 litros de leche en 16 días.

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.

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

x-3y-7=0

Step-by-step explanation:
