Find the value of n that satisfies 2(n+1)! + 6n! = 3(n+1), where $n! = n\cdot (n-1)\cdot (n-2) \cdots 2\cdot 1$.
Answer:
[tex]n = 5[/tex]
Step-by-step explanation:
Given
[tex]2(n+1)! + 6n! = 3(n+1)![/tex]
Required
Find n
Simplify (n + 1)!
[tex]2(n+1)*n! + 6n! = 3(n+1)*n![/tex]
Factorize
[tex]n![2(n+1) + 6] = 3(n+1)*n![/tex]
Divide both sides by n!
[tex]2(n+1) + 6 = 3(n+1)[/tex]
Open brackets
[tex]2n + 2 + 6 = 3n + 3[/tex]
[tex]2n + 8 = 3n + 3[/tex]
Collect like terms
[tex]2n - 3n = 3 -8[/tex]
[tex]-n =-5[/tex]
Multiply both sides by -1
[tex]n = 5[/tex]

__x+6 = 2(-3x + 1) + x - 16
Answer:
-5
Step-by-step explanation:
-5x+6 = 2(-3x + 1) + x - 16
-5x+6 = -6x + 2 + x - 16
-5x+6 = -5x -14
+6≠-14⇒x∈Ф

(−1+√5)/2
Answer:
Square root: sqrt(5) = √ 5 = 2.23606798
Add: -1 + the result of step No. 1 = -1 + 2.23606798 = 1.23606798
Divide: the result of step No. 2 / 2 = 1.23606798 / 2 = 0.61803399nation:
Find the area of the following figure.
252 [tex]cm^{2}[/tex]
400 [tex]cm^{2}[/tex]
312 [tex]cm^{2}[/tex]
300 [tex]cm^{2}[/tex]
Answer:
312 cm²
Step-by-step explanation:
The figure is composed of a rectangle and 2 congruent triangles
area of rectangle = 16 × 12 = 192 cm²
area of 2 triangles = 2 × [tex]\frac{1}{2}[/tex] × 12 × 10 = 12 × 10 = 120 cm²
Area of figure = 192 + 120 = 312 cm²
A truck that can carry no more than 7600 lb is being used to transport refrigerators and upright pianos each refrigerator weighs 250lb and each piano weighs 425 lb. Write and graph an inequality to show how many refrigerators and how many pianos the truck could carry. Will 13 refrigerators and 11 pianos overload the truck? Explain.
Answer:
Step-by-step explanation:
7600 ≥ 250r+425p
7600 ≥ 250(13)+425(11)
7600 ≥ 3,250+4675
7600≥7925
This statement is incorrect. Therefore no, the truck cannot transport that load

Answer:
168 sq inches
Step-by-step explanation:
SA = 2(1.5x6) + 2(1.5x10) + 2(6x10)
= 2(9) + 2(15) + 2(60)
= 18+30+120
= 168 sq inches
Find the gradient of the line passing through the points (4a,-a) and (6a,5a)
Answer:
The gradient of the line passing through the points (4·a, -a) and (6·a, 5·a) is 3
Step-by-step explanation:
The gradient of a (straight) line given the 'x' and 'y' coordinates of two points on the line, (x₁, y₁), and (x₂, y₂) can be found using the following formula;
[tex]The \ gradient \ of \ a \ line, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
The coordinates of two points on the given line are;
(4·a, -a), and (6·a, 5·a)
Therefore, we get;
[tex]The \ gradient \ of \ the \ line =\dfrac{5\cdot a-(-a)}{6 \cdot a-4 \cdot a} = \dfrac{6\cdot a}{2 \cdot a} = 3[/tex]
The gradient of the line = 3.

Show that f(x) = x^2 and g(x) = 1000x^2 grow at the same rate.
Answer:
You do not use the first derivative to find the rate you need to take the limit ratio as x approaches positive infinity. We use positive and not negative infinity because our function is increasing and not decreasing. The ratio ends up being 1/1000 meaning that this a finite non zero number. Which proves that they grow at the same rate

Which statement is true if a tenth data point of 45 is added to the data set?
А
The mean and median will both increase.
B
The mean will increase and the median will decrease.
с

D

SED
Answer:
C.
Step-by-step explanation:
Reorder the data set, from least to greatest.
3, 5, 7, 8, 9, 9, 10, 11, 12
Mean: 8.2 -> you get this by adding up all the numbers in the data set by how many numbers in the data set. For example, 3+5+7+8+9+9+10+11+12= 74 divide by 9 (the numbers in the data set) = 8.2 (repeated infinitely).
Median: 9 -> you get this by finding the number in the middle of the data set, which is why you have to reorder the data set for the beginning to make this easier.
Mean (with 45): 11.9 -> 119 when you add up all the numbers, then divide by 10 because that's have many numbers in the new data set.
Median (with 45): 9 -> When there are two numbers in the middle of the data set, add them up and divide by two. For example, 9+9=18/2= 9
Answer: C.
what is the a, b, and c of the following quadratic y = - 4x ^ 2 + 5x - 3
Answer:
A = -4
B = 5
C = -3
Step-by-step explanation:
Standard form of a quadratic equation is y = Ax² + Bx + C
In the quadratic y = -4x² + 5x - 3, we can use this standard form to find A, B, and C.
Since -4 is the coefficient to x², A is -4.
Since 5 is the coefficient to x, B is 5.
Lastly, since -3 is the last term, C is -3.
So, the answer is:
A = -4
B = 5
C = -3
The are of a rectangular trampoline is 112ft. The length of the trampoline is 6ft greater than the width of the trampoline. This situation can be represented by the equation x^2+6x-112=0 what is the width of the trampoline in feet
Answer:
8cm
Step-by-step explanation:
let x = width
x^2+6x-112=0
we would solve this using the factorization method
the factors of -112x^2 that would add up to 6x are 14x 8x
x^2 - 8x + 14x - 112 = 0
factorise
x(x - 8) + 14(x - 8) = 0
x+ 14 = 0
x - 8 = 0
x = 8
the width is 8cm
x = -14
