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.

a wire 10cm long is cut into two pieces, one of length x and the other of length 10-x. Each piece is bent into the shape of square. find the value of x that minimizes the total rea of the two squres
Answers
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.

m∠RSU = (7x + 3)° and m∠UST = (11x − 21)°. If ∠RSU and ∠UST are complementary, what is the measure of each angle?
Answers
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.
What is the angle?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.

if f(x)=9-4x^2 Find
a) f(-2)
b) f(-3) f(3)
c) x such that f(x) = 0
Answers
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]

3. Una ciudad contrata un escultor para diseñar la escultura “El lápiz”. El diseño
que presenta para la escultura tiene forma y medidas que se muestran en la
imagen, donde la distancia del centro de la base del prisma a cada uno de sus
lados es de 3,4 m y su perímetro es de 24 m. La altura total de la escultura es 5
m. ¿Cuánto volumen de material es necesario para construir la escultura?
Answers
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:
P es el perimetro del hexágono (P = 24 m)a es la distancia del centro a uno de sus lados, apotema. (a = 3,4 m).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:
H es la altura de la pirámide.A(hex) es el área del hexágonoNosotros 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]

Suppose that g(x) = f(x) + 5. Which statement best compares the graph of

Answers
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.
What is vertical shifting?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.
