A) write an explicit formula for the sequence 12, 16, 20, 24 B) Find the 11th term of the sequence *
Answer:
[tex]T_n = 8+ 4n[/tex]
[tex]T_{11} = 52[/tex]
Step-by-step explanation:
Given
[tex]Sequence: 12, 16, 20, 24[/tex]
Solving (a): Write a formula
The above sequence shows an arithmetic progression
Hence:
The formula can be calculated using:
[tex]T_n = a + (n - 1) d[/tex]
In this case:
[tex]a = First\ Term = 12[/tex]
Difference (d) is difference of 2 successive terms
So:
[tex]d = 16 - 12 = 20 - 16 = 24 - 20[/tex]
[tex]d = 4[/tex]
Substitute 4 for d and 12 for a in [tex]T_n = a + (n - 1) d[/tex]
[tex]T_n = 12 + (n - 1) * 4[/tex]
Open Bracket
[tex]T_n = 12 + 4n - 4[/tex]
Collect Like Terms
[tex]T_n = 12 - 4+ 4n[/tex]
[tex]T_n = 8+ 4n[/tex]
Hence, the explicit formula is: [tex]T_n = 8+ 4n[/tex]
Solving (b): 11th term
This implies that n = 11
Substitute 11 for n in: [tex]T_n = 8+ 4n[/tex]
[tex]T_{11} = 8+ 4 * 11[/tex]
[tex]T_{11} = 8+ 44[/tex]
[tex]T_{11} = 52[/tex]
Answer:
A) The explicit formula for the sequence is [tex]f(n) = 12+4\cdot n[/tex], [tex]n \in \mathbb{N}_{O}[/tex].
B) The 11th term of the sequence is 62.
Step-by-step explanation:
A) Let [tex]f(0) = 12[/tex], we notice that sequence observes an arithmetic progression, in which there is a difference of 4 between two consecutive elements. The formula for arithmetic progression is:
[tex]f(n) = f(0) +r\cdot n[/tex] (1)
Where:
[tex]f(0)[/tex] - First value of the sequence, dimensionless.
[tex]r[/tex] - Arithmetic increase rate, dimensionless.
[tex]n[/tex] - Term of the value in the sequence, dimensionless.
If we know that [tex]f(0) = 12[/tex] and [tex]r = 4[/tex], then the explicit formula for the sequence is:
[tex]f(n) = 12+4\cdot n[/tex], [tex]n \in \mathbb{N}_{O}[/tex]
B) If we know that [tex]f(n) = 12+4\cdot n[/tex] and [tex]n = 10[/tex], the 11th term of the sequence is:
[tex]f(10) = 12+4\cdot (10)[/tex]
[tex]f(10) = 62[/tex]
The 11th term of the sequence is 62.

Answer:
12.25Step-by-step explanation:
It is easy to notice that:
QA=QB=QCAs per triangle congruence theorem (two congruent sides and a right angle)
Since:
QB = x + 9 and QC = 5x - 4We have
x + 9 = 5x - 45x - x = 9 + 44x = 13x = 13/4x = 3.25QA = QB = QC = 3.25 + 9 = 12.25

Which value is a solution of the inequalityx∕5 + 2 ≤ 6?
A)
x = 49
B)
x = 15
C)
x = 37
D)
x = 21
Answer:
B
Step-by-step explanation
the answer comes to [tex]x\leq 20[/tex] and 15 is the only answer below 20
Answer:
B. x = 15
Step-by-step explanation:
Firstly we simplify the inequality, so we have x on the left side, and every number on the right side[tex]\frac{x}{5}+2\leq 6\\ \frac{x}{5}+2-(2)\leq 6-(2)[/tex] so we take away 2 on both sides[tex]\frac{x}{5}\leq 4[/tex] now this is the same as [tex]\frac{1}{5}*x\leq 4[/tex] Now we multiply by 5 on both sides [tex]5*\frac{1}{5}*x\leq 5*4[/tex] which is [tex]\frac{5}{5}*x \leq 20[/tex] which is simply [tex]x \leq 20[/tex] since 5 divide by 5 is 1 and 1 times x is xSo the inequality [tex]x \leq 20[/tex] means "every number for x that is less than or equal to 20"Now from the list, the only number that fits is 15. So that's our answerPLEASE HELP ME OUT FASTTTTT
Answer:
1 more slice
Step-by-step explanation:
1/2 of the pizza would be 4 since (8÷2=4)
So since we need 4 pizza slices to be gone in order to make 1/2 of the pizza...
and since we know that there are three slices missing....
the equation for this is 8-3=5 and we can't have 5 we need 4 so we need 1 more slice to be eaten

Answer:
The value of x = 20.05
Step-by-step explanation:
As we know that the sum of the angles in a triangle is 180°.
From the diagram, we can say that the sum of the angles A, B, and C must be 180°.
so the equation of the sum of the angles of a triangle will be:
[tex]A+B+C=180^{\circ }[/tex]
As
[tex]A=43\frac{1}{4}^{\circ }[/tex]
[tex]B=5x^{\circ }[/tex]
[tex]C^{\circ }=36.5^{\circ }[/tex]
Substituting the values in the equation of the sum of the angles of a triangle to find the value of x.
[tex]A+B+C=180^{\circ }[/tex]
[tex]43\frac{1}{4}+5x+36.5=180[/tex]
[tex]\frac{173}{4}+5x+36.5=180[/tex] ∵ [tex]43\frac{1}{4}=\frac{173}{4}[/tex]
Subtract [tex]\frac{173}{4}+36.5[/tex] from both sides
[tex]\frac{173}{4}+5x+36.5-\left(\frac{173}{4}+36.5\right)=180-\left(\frac{173}{4}+36.5\right)[/tex]
[tex]5x=100.25[/tex]
[tex]\frac{5x}{5}=\frac{100.25}{5}[/tex]
[tex]x=20.05[/tex]
Therefore, the value of x = 20.05
VERIFICATION:
[tex]A+B+C=180^{\circ }[/tex]
[tex]43\frac{1}{4}+5x+36.5=180[/tex]
[tex]43\frac{1}{4}+5\left(20.05\right)+36.5=180[/tex]
[tex]180=180[/tex]

Y=-x-6 with slope graph Please help me answer this
Answer: the slope of the graph is -1
Step-by-step explanation: because x has a coefficient of negative 1 but if you wanted to graph this line, you have to be careful since you go down 1 unit and right 1unit. The line is descending since it has a negative slope so technically the slope is -1/1 but we can just say it’s -1

George purchases a sack of apples, a bunch of bananas, a cantaloupe, and a carton of dates for $20. If a carton of dates costs twice as much as a sack of apples and the price of a cantaloupe is equal to the price of a sack of apples minus a bunch of bananas, how much would it cost George to purchase a bunch of bananas and a cantaloupe?
9514 1404 393
Answer:
$5
Step-by-step explanation:
Let the variables A, B, C, D represent a sack of apples, a bunch of bananas, a cantaloupe, and a carton of dates, respectively. Then the problem statement gives rise to 3 equations:
A +B +C +D = 20
D = 2A
C = A -B
Substituting the last two equations into the first gives ...
A +B + (A -B) +2A = 20
4A = 20 . . . simplify
A = 5 . . . . . divide by 4
Substituting this into the last equation, we have ...
C = 5 -B
B + C = 5 . . . . add B
The cost to purchase a bunch of bananas and a cantaloupe is $5.

Answer:
(-1, 1)
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationSolving systems of equations by graphingStep-by-step explanation:
Step 1: Define systems
3 + 2x - y = 0
-3 - 7y = 10x
Step 2: Rewrite systems
3 + 2x - y = 0
Add y to both sides: 3 + 2x = yStep 3: Redefine systems
y = 2x + 3
-3 - 7y = 10x
Step 4: Solve for x
Substitution
Substitute in y: -3 - 7(2x + 3) = 10xDistribute -7: -3 - 14x - 21 = 10xCombine like terms: -14x - 24 = 10xAdd 14x on both sides: -24 = 24xDivide 24 on both sides: -1 = xRewrite: x = -1Step 5: Solve for y
Define original equation: -3 - 7y = 10xSubstitute in x: -3 - 7y = 10(-1)Multiply: -3 - 7y = -10Add 3 to both sides: -7y = -7Divide -7 on both sides: y = 1Step 6: Graph

George the Pigeon travels the same distance of 72 miles
in 4 hours against the wind as he does traveling 3 hours
with the wind in the local skies. What is the speed of
George the Pigeon in still air and the speed of the wind?
Answer:
The speed of George the Pigeon in still air = 21 miles/hr
The speed of air = 3 miles/hr
Step-by-step explanation:
Let the speed of George the Pigeon in still air = [tex]u[/tex] miles/hr
Let the speed of air = [tex]v[/tex] miles/hr
Distance traveled = 72 miles
Relative speed against the wind = [tex](u-v)[/tex] miles/hr
Time taken against the wind = 4 hours
Relative speed with the wind = [tex](u+v)[/tex] miles/hr
Time taken against the wind = 3 hours
Using the formula:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
[tex]u-v=\dfrac{72}{4}\\\Rightarrow u-v=18 ..... (1)[/tex]
[tex]u+v=\dfrac{72}{3}\\\Rightarrow u+v=24 ..... (2)[/tex]
Adding (1) and (2):
[tex]2u=42\\\Rightarrow u = 21\ miles/hr[/tex]
By equation (1):
[tex]v = 21-18\\\Rightarrow v = 3\ miles/hr[/tex]
Therefore, the answer is:
The speed of George the Pigeon in still air = 21 miles/hr
The speed of air = 3 miles/hr
