.......

Step-by-step explanation:

hopefully it is clear and understandable

:)

Step-by-step explanation:

m∠RSU + m∠UST = 90° (as complementary angles)

(7x + 3)° + (11x − 21)° =90°

18x -18° = 90°

18x = 108°

x = 6

so, m∠RSU = (7x + 3)° = 7(6)+3 = 45°

and m∠UST = (11x − 21)° = 11(6) -21 = 45°

The required measures of the angles ∠RSU and ∠UST are 31° and 23° respectively.

The angle can be defined as the one line inclined over another line. Also the angles are measured in radian or degrees.

The sum of the complementary angles is 90.
So,
∠RSU + ∠UST = 90
7x +3 + 11x - 21 = 90
18x - 18 = 90
18 (x - 1) = 90
x - 1 = 90 / 18
x - 1 = 5
x = 4

Required measures of the angles,|

1) m∠RSU = (7x + 3)°
m∠RSU = (7 * 4+ 3)°|

m∠RSU = 31°

2)  m∠UST = (11x − 21)°.
    m∠UST = (11 * 4 − 21)°
    m∠UST = (44 − 21)°
     m∠UST =  23°

Thus, the required measures of the angles ∠RSU and ∠UST are 31° and 23° respectively.

Answer:

B

Step-by-step explanation:

The correct statement is, the graph of g(x) is the graph of f(x) shifted 5 units up.

In geometry, a vertical shift otherwise known as vertical translation, is a translation of a geometric object in a direction parallel to the vertical axis of the Cartesian coordinate system. In simpler terms, it is a shift in which a plane figure moves vertically.

Given that g(x) = f(x) + 5. We need to find that which statement best compares the graph of g(x) with the graph of f(x),

So,

If f is any function of x, then the graph of the function f(x) + c, may be obtained by a vertical translation of the graph of f(x) by distance c.

For this reason, the function f(x) + c is sometimes called a vertical translate of f(x).

Hence, the correct statement is, the graph of g(x) is the graph of f(x) shifted 5 units up.

Answer:

yes the number is divisible by 4 in which we get 171143 without any decimal but if we try to divide it by 8 then we get

85571.5 with decimal include

Answer:

see explanation

Step-by-step explanation:

(a)

To evaluate f(- 2) substitute x = - 2 into f(x) , that is

f(- 2) = 9 - 4(- 2)² = 9 - 4(4) = 9 - 16 = - 7

(b)

Similarly substitute x = - 3 and x = 3 into f(x)

f(- 3) = 9 - 4(- 3)² = 9 - 4(9) = 9 - 36 = - 27

f(3) = 9 - 4(3)² = 9 - 4(9) = 9 - 36 = - 27

(c)

let f(x) = 0 , then

9 - 4x² = 0 ( add 4x² to both sides )

9 = 4x² ( divide both sides by 4 )

[tex]\frac{9}{4}[/tex] = x² ( take the square root of both sides )

± [tex]\sqrt{\frac{9}{4} }[/tex] = x

± [tex]\frac{\sqrt{9} }{\sqrt{4} }[/tex] = x

± [tex]\frac{3}{2}[/tex] = x

That is x = - [tex]\frac{3}{2}[/tex] or x = [tex]\frac{3}{2}[/tex]

Answer:

-2

Step-by-step explanation:

brackets first

12 - 9 = 3

Then square it

3^2 = 9

Now multiply by 2

9*2 = 18

finally get - 5 * 4 = - 20

and put them both together

18 - 20 = - 2

El volumen de material requerido para la construcción de la escultura es:

[tex]V_{tot}=122,26\: m^{3}[/tex]

Esta escultura esta compuesta de dos volúmenes, un prisma de base hexagonal y una pirámide de base hexagonal. Calculemos el volumen de cada figura por separado, para luego sumarlos.

Prisma

La ecuacion del área de un hexágono está dada por:

[tex]A_{hex}=\frac{P*a}{2}[/tex]

Donde:

Entonces el área será:

[tex]A_{hex}=\frac{24*3,4}{2}[/tex]

[tex]A_{hex}=40,8\: m^{2}[/tex]

Ahara, el volumen de un prisma de base hexagonal está dada por:

[tex]V_{prisma}=A_{hex}*h[/tex]

h es la altura del prisma, en nuestro caso h = 2 m.

Entonces:

[tex]V_{prisma}=40,8*2[/tex]

[tex]V_{prisma}=81,6\: m^{3}[/tex]

Pirámide

El volumen de una pirámide de base hexagonal está dado por:

[tex]V_{piramide}=\frac{A_{hex}*H}{3}[/tex]

Donde:

Nosotros tenemos la apotema del volumen 4,53 m, por lo tanto podremos calcular H usadon el teorema de pitagoras.

[tex]4,53^{2}=a^{2}+H^{2}[/tex]

[tex]4,53^{2}=3,4^{2}+H^{2}[/tex]

[tex]H=2,99\: m[/tex]

Por lo tanto el volumen de la pirámide será:

[tex]V_{piramide}=\frac{40,8*2,99}{3}[/tex]

[tex]V_{piramide}=40,66\: m^{3}[/tex]

El volumen total del material necesario será:

[tex]V_{tot}=V_{prisma}+V_{piramide}[/tex]

[tex]V_{tot}=81,6+40,7=122,26\: m^{3}[/tex]

Step-by-step explanation:

Further explanation

We at present undergo the following operations: addition, subtraction, multiplication, and division. When given an expression sometimes we confuse operations which must take precedence.

In the 1500s the rules of the order of operation were issued. The "order" of these operations states which processes take precedence (as a priority) before which other operations.

The priority of operations is:

Brackets (simplify in it)

Exponent

Multiplication and Division (from left to right)

Addition and Reduction (from left to right)

Answer:

The value of x that minimizes the total area of the two squares is x = 5.

Step-by-step explanation:

A wire 10 centimeters long is cut into two pieces, with one piece measuring x centimeters and the other (10 - x) centimeters.

Each piece is bend into the shape of a square, and we want to find the value of x that minimizes the total area of the two squares.

If x is bend into a square with four equivalent sides, then each side measure:

[tex]\displaystyle A = \frac{x}{4}[/tex]

Likewise, each side of the second square will measure:

[tex]\displaystyle A = \frac{10-x}{4}[/tex]

The area of a square is its side squared. Hence, the area of both squares will be given by:

[tex]\displaystyle T = \left( \frac{x}{4}\right) ^2 + \left(\frac{10-x}{4}\right)^2[/tex]

Simplify:

[tex]\displaystyle \begin{aligned} T &= \frac{x^2}{16} + \frac{x^2 - 20x + 100}{16} \\ \\ &=\frac{2x^2-20x+100}{16}\\ \\ &= \frac{1}{8}x^2-\frac{5}{4}x+\frac{25}{4} \end{aligned}[/tex]

Since this is a quadratic with a positive leading coefficient, the minimum value will occur at the vertex point.

Recall that the x-coordinate of the vertex is given by:

[tex]\displaystyle x = -\frac{b}{2a}[/tex]

In this case, a = 1/8 and b = - 5/4. Hence:

[tex]\displaystyle x = -\frac{\left(-\dfrac{5}{4}\right)}{2\left(\dfrac{1}{8}\right)} = 5[/tex]

In conclusion, the value of x that minimizes the total area of the two squares is x = 5.

Answer:

567

Step-by-step explanation:

It is going to be arithmetical sequence, a1=6

d=3, n=18

Sn= (2a1+d(n-1))/2*n= (2*6+3*17)/2*18= 63*9=567

The arrangement of fruits trees in the farm is modeled after an arithmetic progression, thus, there are 567 fruit trees in the farm.

The number of fruits trees in the farm represents an arithmetic progression as each row of trees in the farm increases by 3 more than the one after it.

The number of trees is calculated using the arithmetic formula as follows:

[tex]S_n = \frac{2a + d(n - 1)}{2}× n[/tex]

where

Substituting the values

[tex]S_n = \frac{2 \times 6 + 3(18 - 1)}{2}× 18 = 567[/tex]

Therefore, there are 567 fruit trees in the farm.

Answer:

No solution

Step-by-step explanation:

Distribute the right side of the equation.

This will make it 3/8f+1/2=3/8f - 18

And, since 3/8f plus 1/2 will never equal the same thing as 3/8f minus 18, there are no solutions

Answer and Step-by-step explanation:

First, distribute the 6 to the [tex]\frac{1}{16} f[/tex] and -3.

[tex]\frac{3}{8} f + \frac{1}{2} = \frac{6}{16} f - 18\\\\\frac{3}{8} f + \frac{1}{2} = \frac{3}{8} f - 18[/tex]

If you were to subtract [tex]\frac{3}{8} f[/tex] from both sides of the equation, you would be left with [tex]\frac{1}{2} = -18[/tex], which isn't correct.

This means that there are NO solutions to this equation, or no value of f that will make both sides of the equation equal to each other.

Answer:

Rachel will make 30 free-throws!

Step-by-step explanation:

Hello!

I came up with this solution with some easy mental math! If you weren't aware, 60% of 50 is a whole number! Meaning that 60% of 50 is 30. You could even double 50 to make it 100, everyone knows that dealing with percentages with the number 100 make them a whole lot easier!

Back to what I was saying, if you used 100, you would also have to take 60% of 100, which is 60. And then have to divide 60 by 2 because you doubled the 50! Giving you 30 free-throws, which is the correct answer!

Hope this helped! Let me know if you have any further questions! :)
