Write an explicit formula for a-n, then term of the sequence 36, 39, 42,....
Answer:
a^n = 36 + (n-1) * 3
Step-by-step explanation:
Explicit formula for arithmetic sequences: a^n = a^1 + (n-1) * d
In this case, a^1 = 36 and common difference/d = 3
So...
a^n = 36 + (n-1) * 3 is the explicit formula for this sequence.

Factorise x cubed - x
Answer:
= x(x+1)(x-1)
Step-by-step explanation:
Given the expression x³ - x
On factorizing
x³ - x
= x(x²-1)
Using difference of two square
a² - b² = (a+b) (a-b)
x² - 1
= x² - 1²
= (x+1)(x-1)
The complete factor
x³ - x
= x(x²-1)
= x(x+1)(x-1)

if you spent 6 hours a week studying for English and 2.5 hours studying for math what is the ratio of time spent studying in math to studying for English ?
Answer: If you spend 7 hours a week studying for English, and 4.5 hours studying for math what is the ratio of time spent studying math to studying English?
Math: English
4.5: 7 Now you divide both sides by 4.5 to get 1 on one side
1: 1.555556
So the ratio of time spent studying math to english is 1 to 1.555556. Hope I helped

the winning candidate in an election receives 0.64 of the votes. there are 100 voters. how many votes does the winning candidate receive?
Answer:
64
Step-by-step explanation:
.64 = Sixty-four hundredths or 64/100
That is 64% or 64 voters out of 100
Twelve is not equal to negative four
Ok?? thx for the points
Hi there!
Twelve is not equal to negative four.
So we know that all of the factors of twelve is 1,2,3,4,6, and 12 itself...
None of these are actually -4 since -4 doesn’t equal to 12.
Think about this... when your trying to multiply or add...
[tex]-4+-4=0[/tex]
[tex]0+-4=-4[/tex]
[tex]-4[/tex]·[tex]-4=16[/tex]
If you keep on multiplying or adding it, it’ll always stay the same...
So like always, twelve isn’t equailvalent to -4.

Find the area of these shapes!! Will mark brainliest for right answer
Answer:
for first one
total area =l×b+1/2×b×h=6×4+1/2×2×6=30cm²
Step-by-step explanation:
for second one
total area =l×b+1/2×b×h=7×5+1/2×7×2=35+7=42m²
In the figure above, are <3 and <7 alternate interior angles,
same-side interior angles, corresponding angles, or alternate
exterior angles?
Answer:
Corresponding angles
Step-by-step explanation:
<3 and <7 lie on the same side of the transversal line. Each angle also is located on the outside of each parallel lines cut across by the transversal.
Therefore, <3 and <7 are corresponding angles.

Answer:
Row D
Step-by-step explanation:
y = 2x - 3
if x = 10
y = 2 * 10 - 3
= 20 - 3
= 17
so row d is incorrect.

(I NEED HELP ASAP) What is solution to the inequality: -8x - 15 ≥ 9
Answer:
x ≤ −3
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
CALCULUS: For an object whose velocity in ft/sec is given by v(t) = sin(t), what is its distance, in feet, travelled on the interval t = 1 to t = 5?
A. 0.45
B. 2.82
C. 0.03
The linked answer is wrong because that integral gives you the net displacement of the object, not the total distance.
To get the distance, you have to integrate the speed (as opposed to velocity), which involves integrating the absolute value of the velocity function.
[tex]\mathrm{distance} = \displaystyle\int_1^5 |\sin(t)| \,\mathrm dt[/tex]
By definition of absolute value,
[tex]|\sin(t)|=\begin{cases}\sin(t)&\text{for }\sin(t)\ge0\\-\sin(t)&\text{for }\sin(t)<0\end{cases}[/tex]
Over this particular integration interval,
• sin(t ) ≥ 0 for 1 ≤ t < π, and
• sin(t ) < 0 for π < t ≤ 5
so you end up splitting the integral at t = π as
[tex]\mathrm{distance} = \displaystyle\int_1^\pi \sin(t)\,\mathrm dt + \int_\pi^5 (-\sin(t))\,\mathrm dt[/tex]
Now compute the distance:
[tex]\mathrm{distance} = -\cos(t)\bigg|_1^\pi + \cos(t)\bigg|_\pi^5[/tex]
[tex]\mathrm{distance} = -(\cos(\pi) - \cos(1)) + (\cos(5) - \cos(\pi))[/tex]
[tex]\mathrm{distance} = -2\cos(\pi) + \cos(1) + \cos(5) \approx 2.82[/tex]
making B the correct answer.

Which expression is equivalent to Oy-3?
O 3ty-1)
O 3(3-1)
O 9(y-3)
O 9(3y-3)
Answer:
3(3y-1)
Step-by-step explanation:
To find out which expression is equivalent, expand and simplify the options listed to see which one equals 9y-3.
Let's try the second option. To simplify the expression, use the distributive property. So, multiply each term in the parentheses by 3:
[tex]3(3y-1)\\= 9y-3[/tex]
Thus, the answer would be the second option.
Anyone know the answer to this?
2n^2/6^2+10n-1

During a scuba dive, Lainey descended to a point 23 feet below the ocean surface. She continued her
descent at a rate of 23 feet per minute. Enter an inequality you could solve to find the number of minutes
she can continue to descend if she does not want to reach a point more than 97 feet below the ocean
surface. Use t to represent the variable for the minutes Lainey can continue to descend.
The inequality is
t (select)
t (23) ≤ 97 - 23
The minus 23 at the back represents the feet she already descended before what the question wants us to calculate
≤ is used instead of < because it states more than, not "equal or more than" (meaning 97 sharp is fine)
3.3(x + 1.2) = 40.26
Answer: x=11
Step-by-step explanation:
Answer:
x = 11
Step-by-step explanation:
3.3(x + 1.2) = 40.26
Distribute the 3.3 across the parentheses.
3.3x + 3.96 = 40.26
Combine the constants by subtracting 3.96 from both sides
3.3x = 36.3
Isolate the variable by dividing both sides by 3.3
x = 11
Check your work by plugging x = 11 into the original equation.
3.3(11 + 1.2) = 40.26
3.3(12.2) = 40.26
40.26 = 40.26
Your answer is correct.
Hope this helps!
Q11.
The diagram shows a trapezium.
x-4
Diagram NOT
accurately drawn
2x
x + 5
All the measurements are in centimetres.
The area of the trapezium is 351 cm2.
(a) Show that 2x2 + x - 351 = 0
Answer:
Step-by-step explanation:
The area of a trapezium is given as;
Area = [tex]\frac{1}{2}[/tex](a + b)h
where: a is the length of the upper side, b is the length of its base and h is its height.
This implies that; a = x - 4, b = x + 5, h = 2x and area = 351
Thus,
351 = [tex]\frac{1}{2}[/tex]((x - 4) + (x + 50)) 2x
= (x - 4 + x + 5) x
531 = (2x + 1) x
= 2[tex]x^{2}[/tex] + x
So that;
2[tex]x^{2}[/tex] + x - 531 = 0
This gives a quadratic equation.
A zookeeper is monitoring the supply of grain and hay that she has to feed the
animals for the week. She currently has eight pounds of hay. One pound of hay
feeds the animals for three days. The grain that she has to feed the animals is
shown in the graph below. Given the rate at which the zookeeper is giving the
animals hay and grain, on which day will she have the same amount of grain and hay remaining?
Answer: Day 6
Step-by-step explanation: Every 3 days 1 pound of hay is used every day 1 pound of grain is used. There are 10 pounds of grain and 8 pounds of hay. On the 6th day there are 6 pounds of hay left and 6 pounds of grain left.

8kg ham costs $12/kg. find the cost per pound.
Answer:
The cost per pound is: $5.45 per pound
Step-by-step explanation:
Given
8kg ham costs $12/kg
To determine
Find the cost per pound
As
1 kg = 2.2 pounds
Weight of 8kg in ponds = 8 × 2.2 = 17.6 ponds
Cost of ham/pound = $12/2.2 pounds
= $5.45 per pound
Thus, the cost per pound is: $5.45 per pound
