Given the following arithmetic sequence; starting with 107, which term has a value of -61?
107, 101, 95...-61
(show steps pls)
Answer:
Step-by-step explanation:
The pattern of this sequence is : From a term, we minus 6 to get to the next term
107 - 6 = 101
101 - 6 = 95
So on and so on.
The difference between 107 and -61 is : 107 - (-61) = 168
Everytime we go to the next term, we get 6 units closer to -61
So, -61 will be the 168 : 6 = 28th term of this arithmetic sequence.
The length of a rectangle is 2 centimeters less than its width. What are the dimensions of the rectangle if its area is 168 square centimeters
Given :
The length of a rectangle is 2 cm less than its width.Area of the rectangle is 168 cm²To Find :
The dimensions of the rectangle.Solution :
Let us assume the length of the rectangle as x cm and therefore the breadth will be (x + 2) cmWe know that,
[tex] \purple{ \boxed{\quad \bf Length \times Width = Area_{(rectangle)}}}[/tex]
Now, Putting the values in the formula :
[tex]{ \qquad \sf { \dashrightarrow{ x(x + 2)= 168 {cm}^{2} }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ {x}^{2} + 2x= 168 }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ {x}^{2} + 2x - 168=0 }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ {x}^{2} - 12x + 14x - 168 = 0 }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ {x}(x - 12) + 14(x - 12) = 0 }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ ({x}+ 14)(x - 12) = 0 }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ ({x}+ 14) = 0 }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ {x}= - 14 }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ ({x} - 12) = 0 }}}[/tex]
[tex]{ \qquad \sf { \dashrightarrow{ {x} = 12 }}}[/tex]
Whether x = (–14) or 12The length of the rectangle can never be negative so the length must be 12 cm .
Therefore, Width = (12 + 2) = 14 cm .

Step-by-step explanation:
sinΘ = [tex]\frac{6}{7}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]
This is a right triangle with hypotenuse 7 and opposite side 6
Use Pythagoras' identity to find the adjacent side a
a² + 6² = 7²
a² + 36 = 49 ( subtract 36 from both sides )
a² = 13 ( take square root of both sides )
a = [tex]\sqrt{13}[/tex]
Then
cosΘ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{\sqrt{13} }{7}[/tex] → B

Q10) abc + bca +cba is a monomial *

Step-by-step explanation:
Q1)
for x = 2, y = 1
-8x³y⁴/7 = -64/7
-8×2³×1⁴/7 = -8×8×1/7 = -64/7
true
Q2)
x/4 + x/6 - x/2 = 3/4
is x = -9 ?
bringing everything to 1/12 ...
3x/12 + 2x/12 - 6x/12 = 3×3/12
-x/12 = 9/12
-x = 9
x = -9
true
Q3)
can
1 - 2ab - (a² + b²) = 1 - 2ab - a² - b² be factored as
(1 + a - b)(1 + a + b)
let's multiply
(1 + a - b)(1 + a + b) =
= 1 + a + b + a + a² + ab - b - ab - b² =
= 1 + 2a + a² - b²
this is NOT the same as
1 - 2ab - a² - b²
false
Q4)
The horizontal distance of a point from the y-axis is called abscissa or x coordinate of the point.
3 is the y coordinate of (2, 3) and not the x coordinate.
false
Q5)
(7, 9) and (9, 7)
the x coordinates are different, and the y coordinate are different. so, they are definitely NOT the same point.
this would be like saying 5 hours and 3 minutes is the same as 3 hours and 5 minutes.
false
Q6)
now, this is tricky. there are 4 perfect cubes between 1 and 100 :
1×1×1 = 1
2×2×2 = 8
3×3×3 = 27
4×4×4 = 64
did your teacher mean "exactly 3 perfect cubes" ? because, since there are 4, there are also 3, of course (and 2, and 1).
and did "between 1 and 100" mean including the numbers 1 and 100, or excluding the numbers 1 and 100 ?
so, if excluding 1 and 100, then it is true.
if including 1 and 100 and asking for exactly 3, then it is false.
if including 1 and 100 and truly only asking for 3, then it is true.
Q7)
12³ = 12×12×12 = 144×12 = 1728
true
Q8)
(a+1)(a-1)(a²+1) = (a⁴ -1) ?
let's multiply
(a² + a - a - 1)(a² + 1) = (a²-1)(a²+1) = a⁴ - a² + a² - 1 = a⁴-1
true
Q9)
the areas of the 2 squares are
25a² and 25b²
the sum is
25a² + 25b² = 25(a² + b²)
but
25(a+b)(a-b) = 25(a² - b²)
this is NOT the same.
false
Q10)
abc + bca + cba
a monomial is, roughly speaking, a polynomial which has only one term.
but the given expression has 3 terms.
false

Step-by-step explanation:
Sally is counting the people and animals that live on her farm. She, her brother, and her parents together have 18 cows, 1 horse, 10 goats, and no chickens. Sally picks one at random. Help her determine the likelihood of selecting each type of animal
Using it's concept, it is found that there is a:
0.6207 = 62.07% probability of selecting a cow.0.0345 = 3.45% probability of selecting a horse.0.3448 = 34.48% probability of selecting a goat.0% probability of selecting a chicken.What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, there is a total of 18 + 1 + 10 + 0 = 29 animals, hence:
18/29 = 0.6207.
0.6207 = 62.07% probability of selecting a cow.
1/29 = 0.0345.
0.0345 = 3.45% probability of selecting a horse.
10/29 = 0.3448.
0.3448 = 34.48% probability of selecting a goat.
0/29 = 0.
0% probability of selecting a chicken.

Please, someone. Solve for x.
Combine the fractions on the left side:
9/(x + 2) + 2/(x - 2) = 1
9 (x - 2) / ((x + 2) (x - 2)) + 2 (x + 2) / ((x + 2) (x - 2)) = 1
(9x - 18) / ((x + 2) (x - 2)) + (2x + 4) / ((x + 2) (x - 2)) = 1
(9x - 18 + 2x + 4) / ((x + 2) (x - 2)) = 1
(11x - 14) / ((x + 2) (x - 2)) = 1
Recall the difference of squares identity,
a² - b² = (a + b) (a - b)
which lets us simplify the denominator on the left side as
(11x - 14) / (x² - 4) = 1
For any real numbers a and b, if a/b = 1, then a = b. This means
11x - 14 = x² - 4
which we can rearrange as
x² - 11x + 10 = 0
Factorize the left side:
(x - 10) (x - 1) = 0
Then
x - 10 = 0 or x - 1 = 0
x = 10 or x = 1
