The solution of the given equation [tex](4)^{3\sqrt{x} -2}[/tex] + 1 = 9 will be x = 1.08.
What is a equation?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
Given is the following equation -
[tex](4)^{3\sqrt{x} -2}[/tex] + 1 = 9
The given equation is -
[tex](4)^{3\sqrt{x} -2}[/tex] + 1 = 9
[tex](4)^{3\sqrt{x} -2}[/tex] = 8
Assume 3[tex]\sqrt{x}[/tex] = n. Then, we can write the equation as -
(4)ⁿ ⁻ ² = 8
(4)ⁿ ÷ (4)² = 8
(4)ⁿ x 1/(4)² = 8
(4)ⁿ = 8 x 16
(2)²ⁿ = (2)³ x (2)⁴
2n = 3 + 4
2n = 7
n = 7/2
3[tex]\sqrt{x}[/tex] = 7/2
[tex]\sqrt{x}[/tex] = 7/6
x = 1.08
Therefore, the solution of the given equation [tex](4)^{3\sqrt{x} -2}[/tex] + 1 = 9 will be
x = 1.08.

What is the value of f(3) ?
Answer:
f(3)=-60
Step-by-step explanation:
f(3)=5*(3^2)-7(4*3 + 3)
f(3)=5*9 - 7*15
f(3)=45-105
f(3)=-60
Answer: -60
Step-by-step explanation:
f(3) means that you replace the input function of x with 3; So, your equation would look something like this:
5(3)^2 - 7(4(3) +3)
= 5(9) - 7(15)
= 45 - 105
= -60

Answer:
a. x = 8 yearsb. 52,000Step-by-step explanation:
company A = 28,000 + 3,000 (x)
company B = 36,000 + 2,000 (x)
where x = no. of years.
company A = company B28,000 + 3,000 (x) = 36,000 + 2000 (x)
3,000 (x) - 2,000 (x) = 36,000 - 28,000
1,000 (x) = 8,000
x = 8,000
1,000
x = 8 yearsplugin value of x = 8 into company A and Bcompany A = 28,000 + 3,000 (8)
company A = 52,000company B = 36,000 + 2,000 (8)
company B = 52,000Un hacendado a comprado doble numero de vacas que de bueyes, por cada vaca pago 70 dólares y por cada buey 85 dólares, si el importe de la compra fueron 2,700 dólares cuantas vacas y bueyes compro
Responder:
Número de bueyes = 12
Número de vacas = 24
Explicación paso a paso:
Dado que :
Número de vacas compradas = 2 veces el número de bueyes;
Sea número de bueyes = y
Número de vacas = 2 años
Costo de la vaca = 70
Costo de bueyes = 85
Costo total = 2700
Por lo tanto;
(2 años * 70) + (y * 85) = 2700
140 años + 85 años = 2700
225 años = 2700
225 años / 225 = 2700/225
y = 12
Número de bueyes = y = 12
Número de vacas = 2y = 2 * 12 = 24

Right.
Step-by-step explanation:
The answer is right on edge2020 I just took the test.
The direction in which the parabola will open is; To the right
What is the equation of a parabola?We are given;
The vertex of the parabola is at (0, 0)
Directrix of the parabola is x = -4
We know that when the vertex of the parabola is (0, 0) and the directrix is x = - a, the parabola will have the form;
y² = 4ax
Thus, we can conclude that the parabola opens towards the right.

Find three consecutive integers with a sum of -36. First, write an equation, then solve.
The graph of g is a horizontal stretch by a factor of 2 and a translation 2 units up, followed by a reflection in the y-axis of the graph of
f(3) = 8x2 - 6. Write a rule for g. Then identify the vertex.
The vertex is
Answer:
f(x)=8x^2-6
f(x) = a (x -h)2 + k
horizontal stretch by a factor of 2 -> 1/2 x
2 units up -> k = 2
reflection in y axis -> x value is negative
g(x) = 8*(1/2 x)2 - 6 + 2
g(x) = 2 x2 -4
Step-by-step explanation:
The vertex will be at g(x) = 2x² -4.
What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data. A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given that the graph of g is a horizontal stretch by a factor of 2 and a translation 2 units up, followed by a reflection in the y-axis of the graph of
f(3) = 8x² - 6.
f(x)=8x²-6
f(x) = a (x -h)2 + k
Horizontal stretch by a factor of 2 -> 1/2 x
2 units up -> k = 2
Reflection in y axis -> x value is negative.
g(x) = 8 x (1/2 x)² - 6 + 2
g(x) = 2x² -4
Therefore, the vertex will be at g(x) = 2x² -4.

The diagram shows a circle drawn inside a square.
The circle touches the edges of the square.
18 cm
Calculate the total shaded area.
Take it to be 3.142 and write down all the digits given by your calculator.
Answer:
69.498
Step-by-step explanation:
first find the area of the whole square (how i saw it), remember
it is made up of a circle drawn inside a square.
so we do the area of the square = 18²
= 324
next we find the circle which was drawn, the circle covers up the
whole shaded square.
diameter would be 18 as the length of the square was 18,
then we find the radius, 18/2 = 9
now we use πr²,
r would be the radius (9)
therefore it would be π(81) and we get 254.502
now we take away the area of the circle covering the square
from the area shaded in,
therefore 324 - 254.502
= 69.498

El entrenamiento que hace marco 10 dias antes de su carrera es constante. Diariamente corre 45 minutos a una velocidad de 30 km-h ¿Cuántos kilómetros ha corrido Marcos durante esos 10 dias?
Responder:
225 kilometros
Explicación paso a paso:
Dado que :
Velocidad de funcionamiento = 30 km / h
Duración = 45 minutos
Número de días = 10 días
Distancia total recorrida por día:
Duración en horas:
45 minutos / 60 = 0,75 hora (s)
Así, la distancia recorrida por día:
Tiempo de velocidad
30 km / h * 0,75 h = 22,5 km
Por lo tanto, la distancia total recorrida durante 10 días:
Distancia recorrida diariamente * 10
22,5 kilometros * 10 = 225 kilometros
