Answer:
Zero solutions; there are no variables and thus there are no solutions
Step-by-step explanation:
We start out with the equation 9 (x - 3) + 15 = 9x - 11
Which simplifies to 9x - 27 + 15 = 9x - 11
The 9x terms cancel each other out, and we're left with 15 - 27 = -11
And we end up with -12 = -11, which is not true.
This tells us that the equation has zero solutions, because no matter what value we substitute for x, the equation will not be true.
Answer:
No solution
Step-by-step explanation:
9(x-3)+15= 9x-11
9x-27+15=9x-11
-15 on both sides
9x-27=9x-26
add 26 on both sides
9x -1=9x
add 1 on both sides
9x=9x+1
divide 9 on both sides
x=x+1/9
No solution
3. A scientist recorded the movement of a pendulum for 10 s. The scientist began recording when the pendulum was at its resting position. The pendulum then moved right (positive displacement) and left (negative displacement) several times. The pendulum took 4 s to swing to the right and the left and then return to its resting position. The pendulum’s furthest distance to either side was 6 in. Graph the function that represents the pendulum’s displacement as a function of time.
(a) Write an equation to represent the displacement of the pendulum as a function of time.
(b) Graph the function.

Cuatro meses después que se detuviera la publicidad, una compañia fabricante notifica que sus ventas han caido de 100.000 unidades por mes a 80.000. Si las ventas siguen un patron de decrecimiento exponencial, cuantas unidades habra despues de los siguientes dos meses?
Answer:
51,200 unidades
Step-by-step explanation:
Paso 1
Calculamos el porcentaje de disminución
= 100000 - 80000/100000 × 100
= 20000/100000 × 100
= 20%
Por lo tanto, el porcentaje de disminución cada mes = 20%
Paso 2
La fórmula de la disminución exponencial
y = a (1 - r) ^ t
a = 80.000
r = 20% = 0,2
t = tiempo en meses = 2
y = 80000 (1 - 0,2) ^ 2
y = 51.200 unidades
Usando una función exponencial, se encuentra que habra 71.554 unidades despues de los siguientes dos meses.
Una función exponencial decreciente tiene el siguiente formato:
[tex]A(t) = A(0)(1 - r)^t[/tex]
En que:
A(0) es la cuantia inicial.r es la tasa de desintegración.En este problema:
Inicialmente, 100000 unidades por mes, o sea, [tex]A(0) = 100000[/tex].Cuatro meses después, 80000 unidades por mes, o sea, cuando [tex]t = 4, A(t) = 80000[/tex], e esto es usado para encontrar r.[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]80000 = 100000(1 - r)^4[/tex]
[tex](1 - r)^4 = 0.8[/tex]
[tex]\sqrt[4]{(1 - r)^4} = \sqrt[4]{0.8}[/tex]
[tex]1 - r = 0.945742[/tex]
Por eso:
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]A(t) = 100000(0.945742)^t[/tex]
Apos el siguinte dos meses, hay el mes 6, por eso:
[tex]A(6) = 100000(0.945742)^6 = 71554[/tex]
Habra 71.554 unidades despues de los siguientes dos meses.

After swimming 60 feet below the surface of water, a whale swims up 30 feet. Use a number line to help you create an equation that shows the new location of the whale in relation to the water service.
A. The equation is -60 + (-30) = -90. The whale is 90 feet below the waters surface.
B. The equation is -60 + (-30) = -30. The whale is 30 feet below the water surface.
C. The equation is -60 + 30 = -30. The whale is 30 feet below the water surface.
D. The equation is -60 + 30 = -90. The whale is 90 feet below the water surface.
Answer:
C. The equation is -60 + 30 = -30. The whale is 30 feet below the water surface
Step-by-step explanation:
At the surface of the water in the swimming pool, the height of elevation is 0.
Thus, if you swim 60 ft below the surface, it means you are going in the negative direction when we consider a number line. Thus, distance = -60 ft
Now, when you swim back up by 30 ft, it is in the positive direction. Thus, total distance is now; -60 + 30 = -30 ft
Thus value denotes a negative direction and it means you are 30 ft below the surface of the water.

In ∆ABC,
∠A = 60°∠B = 60°BC = 12 units∠BDC = 90°To Find :Area of ∆ABC = ?Solution :As, we have :
∠A = 60°∠B = 60°So, By angle sum property of triangle :
∠A + ∠B + ∠C = 180°
[tex] \tt : \implies 60\degree + 60\degree + \angle C = 180\degree[/tex]
[tex] \tt : \implies 120\degree + \angle C = 180\degree[/tex]
[tex] \tt : \implies \angle C = 180\degree - 120\degree[/tex]
[tex] \tt : \implies \angle C = 60\degree[/tex]
Now, we have :
∠A = 60°∠B = 60°∠C = 60°As, all angles are of same length, therefore it is a equilateral triangle.
We know that sides of equilateral triangle are equal.
[tex] \tt : \implies AB = BC = AC[/tex]
Now, we have BC = 12 units.
Hence, all sides are of 12 units.
Now, we know that area of equilateral triangle is :
[tex] \large \underline{\boxed{\bf{Area_{(equilateral \: triangle)} = \dfrac{\sqrt{3}}{4} side^{2}}}}[/tex]
[tex] \tt : \implies Area = \dfrac{\sqrt{3}}{4} \times (12 \: units)^{2}[/tex]
[tex] \tt : \implies Area = \dfrac{\sqrt{3}}{\cancel{4}} \times \cancel{144} \: units^{2}[/tex]
[tex] \tt : \implies Area = \sqrt{3} \times 36 \: units^{2}[/tex]
[tex] \tt : \implies Area = 36\sqrt{3} units^{2}[/tex]
So, Area of given triangle is 36√3 units².

Put the following equation of a line into slope-intercept form, simplifying all fractions.
2x+8y=24
Answer:
y = - [tex]\frac{1}{4}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
2x + 8y = 24 ( subtract 2x from both sides )
8y = - 2x + 24 ( divide all terms by 8 )

A restaurant makes pizzas with 6-inch diameters ad 12-inch diameters. Which of the following statement is true?
The area of the 12-inch pizza is twice the area of the 6- inch pizza
The area of the 12-inch pizza is three times the area of the 6-inch pizza
the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza
the area of the 6-inch pizza is 1/6 the area of the 12-inch pizza
Answer:
The correct option is c: the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza.
Step-by-step explanation:
The area (A) of each pizza is given by:
[tex] A = \pi r^{2} [/tex]
Where:
r: is the radius
For the 12-inch pizza we have:
[tex] A_{12} = \pi (\frac{12 inch}{2})^{2} = 113.1 inch [/tex]
And for the 6-inch pizza we have:
[tex] A_{6} = \pi (\frac{6 inch}{2})^{2} = 28.3 inch [/tex]
The ratio between A₆ and A₁₂ is:
[tex] \frac{A_{6}}{A_{12}} = \frac{28.3 inch}{113.1 inch} = 0.25 = \frac{1}{4} [/tex]
Hence:
[tex] A_{6} = \frac{A_{12}}{4} [/tex]
Therefore, the correct option is c: the area of the 6-inch pizza is 1/4 the area of the 12-inch pizza.
I hope it helps you!
The area of the 6-inch pizza is 1/4 the area of the 12-inch pizza
Given that;Diameter of pizza A = 12 inch
Diameter of pizza B = 6 inch
Computation:Ration of Area of Pizza A to B = [πr1²] / [πr2²]
Ration of Area of Pizza A to B = [(12/2)²] / [(6/2)²]
Ration of Area of Pizza A to B = [(6)²] / [(3)²]
Ration of Area of Pizza A to B = 36 / 9
Ration of Area of Pizza A to B = 4:1
So,
Option "C" is the correct answer of the following question.

Find the sum of the first 33 terms of the following series, to the nearest
integer.
2,8, 14, ...
Answer:
3234
Step-by-step explanation:
The series is arithmetic with a common difference = d = 6
First we need to find the 33rd term. Use the formula [tex]a_{n} = a_{1} + (n - 1)d[/tex] where n = 33 and [tex]a_{1} = 2[/tex]
[tex]a_{33} = 2 + (33 - 1)6 = 2 + 32(6) = 194[/tex]
Now the formula for the sum of an arithmetic series is [tex]S_{n} = \frac{n(a_{1} + a_{n} )}{2}[/tex]
So, [tex]S_{33} = \frac{33(2 + 194)}{2}[/tex]
= [tex]\frac{33(196)}{2}[/tex]
= 3234

Renee bought 7 potatoes at the supermarket. The shortest diameter of each, in centimeters, is shown below
Answer:
2, 3, 4
Step-by-step explanation:
Renee bought 7 potatoes at the supermarket. The shortest diameter of each,
in centimeters, is shown below.
2, 3, 4, 4, 6, 6, 7
After Renee used one potato to make dinner, the median diameter of the remaining potatoes was 5 centimeters. Which of these could be the diameter, in centimeters, of the potato Reneetsed?
Solution:
The median of a group of numbers is the middle number when the group of numbers are arranged in a sorted manner, either ascending or descending.
The median of an even group of numbers, is gotten by taken the average of the two innermost numbers.
Given that the diameter of the potato as:
2, 3, 4, 4, 6, 6, 7
Given that after removing one potato, the median of the remaining potatoes was 5 centimeters.
After removing one potato, the remaining would just be 6. 6 is an even number, hence the median would be the average of the 2 middle numbers.
To get 5 cm, it has to be the average between 4 and 6. This is only possible when a potato of diameter 2,3 or 4 is removed.
If potato with diameter 2 is removed, the remaining is 3, 4, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
If potato with diameter 3 is removed, the remaining is 2, 4, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
If potato with diameter 4 is removed, the remaining is 2, 3, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
