Step-by-step explanation:

we multiply 7×2

A component of the interval is x (π/4, 5π/4) when 5 sin(x) > 5 cos(x).

A relation in mathematics that compares two numbers or even other mathematical expressions in an unequal way is known as an inequality. When comparing two numbers on a number line, it is most frequently used to compare their sizes.

5 sin(x) > 5 cos(x)

To removing constant we divide both the side by 5:

5sin(x) > 5 cos(x)

sin(x) >  cos(x)

sin x > cos x;

sin x = cos x; tan x = 1; x = π/4 or x = 5π/4

sin x > cos x for x ∈ (π/4, 5π/4)

A component of the interval is x (π/4, 5π/4) when 5 sin(x) > 5 cos(x).

Answer:

Hello,

Step-by-step explanation:

1. We must decompose the conic into 2 lines.

[tex]f(x,y)=x^2-5xy+y^2+5x-2y+1=0\\\\We\ are\ going\ to\ find\ the\ center\\\\\left\{\begin{array}{ccc}\dfrac{ \partial{f} }{\partial{x} }&=&12x-5y+5=0\\\\\dfrac{ \partial{f} }{\partial{y} }&=&-5x+2y-2=0\\\end {array} \right.\\\\\\\left\{\begin{array}{ccc}x=0\\y=1\\\end {array} \right.\\\\We\ must\ find\ an\ other\ point\ of\ f(x,y).\\\\if\ y=0\ then\ x=\dfrac{-1}{2} \ or\ x=\dfrac{-1}{3}[/tex]

The 2 lines are: 2x-y+1=0 and 3x-y+1=0

Paralleles are y=2x and y=3x

Perpendiculars are x+2y=0 and x+3x=0

The graph of function f(x) = [tex]2^{x}[/tex] + 3 will be increases without bound As x increases without bound and As x decreases without bound, f(x) approaches the line y = 3 therefore option (C) and (D) will be correct.

A graph is a diametrical representation of any function between the dependent and independent variables.

The graph is easy to understand behavior of the graph.

Given the function,

f(x) = [tex]2^{x}[/tex] + 3

At x = 0 → f(0) = 2⁰ + 3 = 3

This is an exponential function as shown below which will be increasing as x increase while it will gain the value y = 3 as x decrease.

Hence "The graph of function f(x) = [tex]2^{x}[/tex] + 3 will be increases without bound As x increases without bound and As x decreases without bound, f(x) approaches the line y = 3".

Answer:

-8/3 < -2 1/2 < 9/2 < 4 3/4

Step-by-step explanation:

-2.667 < -2.5 < 4.5 < 4.75

Step-by-step explanation:

-282.02 its korrect now

Step-by-step explanation:

could it be that the equation is rather

-5 = (-8 + v)/3

?

that is a huge difference ...

to solve such an equation we keep transforming it (every change we make we have to do on both sides of the equation to keep the equality), until we have only the variable on one side, and everything else (which is then the solution) on the other side.

1st step : we get rid of the "/3" by multiplying both sides by 3.

that gives us

-5×3 = ((-8 + v)/3)×3 via the multiplication property.

2nd step : we simplify

-15 = -8 + v

3rd step : we get rid of the -8 on the side of the variable by adding 8 to both sides.

that gives us

-15 + 8 = -8 + 8 + v via the addition property.

4th step : we combine like terms (or simplify, if we can use it a second time) :

-7 = 0 + v

-7 = v

that's it.

Answer:

60

Step-by-step explanation:

divide 39 by 65%,

you will get
39 / ( 65/ 100)
= 39 * (100/65)
= 39 * (20 /13)
= 3*20
= 60

Step-by-step explanation:

In the equation y = mx + b for a straight line, the number m is called the slope of the line. In the equation y = mx + b for a straight line, the. number b is called the y-intercept of the line.

El grafico de la ecuación lineal se puede ver en la imagen al final.

En este caso queremos graficar la ecuación lineal:

5y - 15 = -4x

Para ello debemos encontrar dos puntos en la linea, y para hacer eso podemos evaluar en dos valores de x.

Sí x = 0 obtenemos:

5y - 15 = -4*0

5y = 15

y = 15/5 = 3

Sí x= 5 obtenemos:

5y - 15 = -4*5

5y = -20 + 15

5y = -5

y = -5/-5 = -1

Entonces solo tenemos los dos puntos (0, 3) y (5, 1), ahora debemos graficar estos en un eje de coordenadas y trazar una linea que pase por ambos, como en el ejemplo de abajo.

Step-by-step explanation:

A rule for subtracting polynomials

Steps

At the end of the expression is (7x²- 4x + 12) + -4x² - 2x + 1

At this point you combine like terms like you do with adding polynomials so ( 7x² + (-4x²) is 3x², (-4x) + (-2x) is (-6x), and 12 + 1 is 13) so the final answer would be 3x²-6x+13

Yes,  the moving boxes will fit in this volume.

The current volume of box :

Volume = height * width * depth

Volume = 12 * 9 * 2

Volume = 216 in³

Answer: -48

Step-by-step explanation:

k/3 + 16

find the roots by factoring

which leads to -48

k/3 + 16

To add or subtract expressions, expand them so their denominators are the same. Multiply 16 by 3/3.

                   k/3 + 16 × 3/3

Since k/3 and 16 × 3/3 have the same denominator, we join their numerators to add them.

                          k + 16 × 3/3

We perform the multiplications in k+16×3.

Blue whale is 15 times longer than otter.

To find how many times the blue whale is  longer than the otter, we will perform division. We will divide the length of blue whale by length of otter, which we will give us the desired result.

Now, performing calculation as per the above statements -

Number of times longer length = [tex]\frac{3*10^{4} }{2*10^{3} }[/tex]

Performing division of numbers. Also, as we know, on division the exponents are subtracted. Hence, subtracting the exponents to get the desired result.

Number of times longer length = 1.5*[tex]10^{4-3}[/tex]

The result will be -

Number of times longer length = 1.5*10

Performing multiplication -

Number of times longer length = 15

Hence, we get that blue whale is 15 times longer than otter.

If 1/2 cup of soup equals 120 milliliters, then there are 780 milliliters in

3 1/4 cups of soup.

A milliliter is a metric unit that is abbreviated as ml and is used to measure volumes for liquid and gas states. It is usually used to measure smaller volumes of liquids as it is equal to 1/1000 of a liter.

We can find the milliliters in 3 1/4 cups of soup as follows:

1/2 cup of soup = 120 milliliters

As 1/2 = 0.5

We can rewrite it as:

0.5 cup of soup = 120 milliliters

3 1/4 cups = 3.25 cups

Consider milliliters in 3 1/4 cups = x

Therefore,

0.5 cup = 120 ml

3.25 cups= x

Cross multiply to find x,

0.5 x = 120x3.25

0.5 x = 390

x= 390/0.5 = 780 milliliters

Hence it is found that 3 1/4 cups of soup is equal to 780 milliliters.

Answer:

1.5797 x 10^-4

Step-by-step explanation:

The area of the six-sided polygon = 220.5 square ft.

Given that the six-sided polygon consists of two isosceles triangles and a rectangle. So the total area to be cut will be equal to the sum of areas of the triangles and the rectangle.

First triangle has base = 15 ft and height = 15 ft

Area of a 1st triangle = 1/2 x base x height

                             = 1/2 x 15 x 15

                             = 112.5 square feet

Second triangle has base = 4 ft and height = 4 ft

Area of the 2nd triangle = 1/2 x base x height

                                        = 1/2 x 4 x 4

                                        = 8 square ft

The rectangle has length = 25 ft and width = 4 ft

Area of the rectangle = length x width

                                    = 25 x 4

                                    = 100 square ft

So the total area of the six-sided polygon = 112.5 + 8 + 100

                                                                      = 220.5 square ft.
