Answer:

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:

90degree because of O is center of circle and mAB come from radius

Step-by-step explanation:

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.

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

Part A: The right triangles are smiliar because If the lengths of the hypotenuse and a leg of a right triangle are proportional to the corresponding parts of another right triangle, then the triangles are similar.

Part B: 2z:2x or 2z/2x. You can write z/x as z:x. Then just multiply both sides by the same number to get an equivalent ratio. Let's multiply by 2. then the answer will be: 2z:2x or 2z/2x

Step-by-step explanation:

For the considered two right triangles, the evaluations for sub-parts of the problem are as follows:

Two triangles are similar if two corresponding angles of them are of same measure. It is because when two pairs of angles are similar, then as the third angle is fixed if two angles are fixed, thus, third angle pair also gets proved to be of same measure. This makes all three angles same and thus, those two triangles are scaled copies of each other. Thus, they're called similar.

Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle.

In a right angled triangle, two such angles are there which are not right angled(not of 90 degrees).

The slant side is called hypotenuse.

From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.

From that angle (suppose its measure is θ),

[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}\\\cos(\theta) = \dfrac{\text{Length of Base }}{\text{Length of Hypotenuse}}\\\\\tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}\\\\\cot(\theta) = \dfrac{\text{Length of base}}{\text{Length of perpendicular}}\\\\\sec(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of base}}\\\\\csc(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of perpendicular}}\\[/tex]

For the considered case of the specified two right angled triangles, we get the solutions to the parts given in the problem as:

Part 1: The right angled triangles have one angles as of 90 degrees. In the image given, it can be seen that the other angle is of [tex]\alpha[/tex] measures, which is also common in both the triangles.

Thus, two angle pairs in both the given triangles are of same measure. That makes both the specified triangles as a pair of similar triangles.

Part 2: The specified ratio is z/x. From the perspective of angle [tex]\alpha[/tex] , we see that z is serving as hypotenuse, and x is base, thus, the ratio z/x is sec([tex]\alpha[/tex] ) (as sec of an angle is ratio of hypotenuse to base)

Part 3: From the perspective of angle [tex]\alpha[/tex] , the perpendicular is the side 'y' and the base is side with length 'x' (we're considering first triangle here, as we can consider any one of them as both are similar).
Thus, we get tan of [tex]\alpha[/tex] as:

[tex]\tan(\alpha) = \dfrac{y}{x}[/tex]

Part 4: The values of the trigonometric ratios depend only on the angle(as they're functions of angles only) because they are ratio.

If a triangle is right angled, and has a specific angle, then whatever the side be, if that angle along with right angle is kept same, the triangles will be similar . That makes their sides a specific multiple of each other.

a side of one triangle = k times corresponding side of its similar triangle

where k is the scale factor, constant for one pair of similar triangles. Now when we will take their ratio, the value of k cancels out, leaving no difference between first triangle or second triangle, but only caring if they are similar or not(which depends on angles).

Thus, the trigonometric functions depend only on angles.

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
