Answer:

tan x

Step-by-step explanation:

(tan-x)[sec(pi/2)-x] (sin-x)

We know that tan (-x) = - tan (x)  and sin (-x) = - sin (x)

-(tanx)[sec(pi/2)-x] -(sinx)

(tanx)[sec(pi/2)-x] (sinx)

Using the identity sec = 1/ cos

sec ( pi/2 -x) =1/cos ( pi /2 -x)

We know that cos (s-t)=cos (s) cos(t) + sin (s) sin (t)

1/ ( cos  pi/2  cos x + sin pi/2 sin x) = 1/(0 cos x - 1 sinx) = 1 / sinx

Replacing into the equation

Composite functions
g(d) = 2d - 5
h(d) = -4d +3
Find (hºg)(d)

Answers

Answer:

[tex](h\circ g)(d)=-8d +23[/tex]

Step-by-step explanation:

Composite Function

Given g(d) and h(d) real functions, the composite function named (hog)(d) is defined as:

[tex](h\circ g)(d)=h(g(x))[/tex]

For practical purposes, it can be found by substituting g into h.

The functions g and h are given as:

[tex]g(d) = 2d - 5[/tex]

[tex]h(d) = -4d +3[/tex]

Substituting g into h:

[tex](h\circ g)(d)=-4(2d - 5) +3[/tex]

Operating:

[tex](h\circ g)(d)=-8d +20 +3[/tex]

[tex]\boxed{(h\circ g)(d)=-8d +23}[/tex]

The 7th grade class experienced a 15% decrease in enrollment.Last year,the 7th grade class had 280 students. How many how many students are enrolled in the 7th grade this year?

Answers

Answer: 238

Step-by-step explanation: 10% of 280 is 28. 1% of 280 is 2.8. Multiply 2.8 times 5 and you get 14. Add 10% and 5% (28+14) and you get 15% which is 42. Subtract 42 from 280 and you get 238.

Answer:

232 students are enrolled this year.

Step-by-step explanation:

Since 15% of the enrollment of the previous year is gone, you must take 15% of the total number of students and subtract that from the total number of students.

[tex]280*0.15=42[/tex]

This tells us that the 15% decrease means there are 42 fewer students enrolled this year. Now you would just subtract 42 from 280.

280 - 42 = 232

Stephanie took a science exam that had two parts. Part 1: She got 16 questions correct, which was 45 of the number of part 1 questions. Part 2: She got 16 questions correct, which was 23 of the number of part 2 questions. What was the total number of questions on Stephanie's exam?

Answers

Given :

Stephanie took a science exam that had two parts. Part 1: She got 16 questions correct, which was 4/5 of the number of part 1 questions. Part 2: She got 16 questions correct, which was 2/3 of the number of part 2 questions.

To Find :

The total number of questions on Stephanie's exam.

Solution :

Let, number of questions in Part 1 is x :

[tex]16=\dfrac{4}{5}x\\\\x=20[/tex]

Let, number of questions in Part 2 is y :

[tex]16=\dfrac{2}{3}y\\\\y=24[/tex]

Therefore, total number of questions on Stephanie's exam are 20 + 40 = 60.

Hence, this is the required solution.

A concentrated cleaning solution must be mixed with water in a container that allows users to spray onto the surfaces they need to clean. Pam’s mom asked her to add 30 ounces of cleaning concentrate into the sprayer and then add water to fill the sprayer. Her father told her that the sprayer must contain 20% cleaning concentrate and 80% water.


a. How many ounces does the sprayer hold?
ounces

b. How much water was added to the sprayer?
ounces

Answers

Answer: The sprayer can hold 150 ounces, and Pam needs to add 120 ounces of water.

Step-by-step explanation:

The data that we know is:

We must use 30 oz of cleaning concentrate.

The end product must be 80% water and 20% cleaning concentrate.

This means that:

Mass of water/total mass in the sprayer = 0.8

mass of cleaning concentrate/total mass in the sprayer = 0.2

Then, let's define the variables:

X = ounces that the sprayer can hold.

Y = ounces of water added.

Then we have the equations:

30oz + X = Y.

30oz/Y = 0.20

X/Y = 0.80

From the second equation we can find the value of Y.

30oz = 0.20*Y

30oz/0.20 = Y = 150oz.

Then the sprayer can hold 150 ounces.

Now from the third equation we have:

X/Y = 0.8

We know that Y = 150oz

Then:

X/150oz = 0.8

X = 0.8*150oz = 120 oz.

Then the water that must be added is 120 ounces.

How do horizontal and vertical translations each affect the coordinates of the points on a figure.

Answers

Answer:

Hi there!

Your answer is:

Perform the translation:

x-10

y-3

Step-by-step explanation:

A translation is how many units X moved left/right and how many units Y moved up/down!

In your case, X went left and Y went down! This means there was  a DECREASE in both of these values!

We can determine this by choosing one point and counting how many units it moved.

Lets use the point on figure 1 at (2,5)

Where did it move on figure 2? (-8, 2)

How many units left did it go? 10!

How many units down did it go? 3!

Rigid transformations is preservative of the distance between pairs of points on the figure. Horizontal and vertical translations are rigid motion transformation such that the shape and size of the figure do not change;

The sequence of translation used to move Figure 1 onto Figure 2 is T₍₋₁₀, ₋₃₎

Translate Figure 1, ten units left and three units down to move Figure 1 onto Figure 2

The reason the above sequence is correct is as follows:

Given that translations are rigid motion, we have;

The sequence of translation that will move a point on Figure 1 to the corresponding point on Figure 2 is the same as the sequence of translation used to move Figure 1 to Figure 2

The coordinates of the point on the top right corner of Figure 1 is (6, 8)

The coordinates of the corresponding point in Figure 2 is (-4, 5)

The sequence of translation, T, is given by the difference of the coordinates as follows;

The sequence of translation is T₍₍₍₋₄₎ ₋ ₆₎, ₍₅ ₋ ₈₎₎ = T₍₋₁₀, ₋₃₎

Therefore, the sequence of translation are;

1) Shift Figure 1,  10 units to the left then 2)  Shift Figure 1, 3 units down to move Figure 1 to Figure 2

Una empresa comercial vende automóviles cuyo precio es de S/. 60 000, con una cuota inicial del 20%, para cancelar el saldo en 30 meses de plazo.calcula la cuota fija mensual que se pagará seda empresa cobra una tasa de interés simple del 12% semestralmente

Answers

Responder:

2560

Explicación paso a paso:

Dado lo siguiente:

Precio del automóvil = 60000

Cuota inicial = 20% del precio = (0.2 * 60000 = 12,000

Saldo = (60000 - 12000) = 48000

La empresa cobra un interés simple del 12% cada 6 meses

Periodo de pago = 30 meses / 6 = 5 periodos

Interés simple: p * r * t

= 48000 * 0,12 * 5 = 28800

Por lo tanto, monto total a reembolsar, incluidos los intereses:

Balance + 28800; 48000 + 28800 = 76800

El reembolso mensual es fijo;

Por lo tanto,

76800/30 = 2560
