[tex]\\ \rm\bull\rightarrowtail y=18[/tex]
Answer:
36 -18
18
Step-by-step explanation:
This is slightly confusing, since the question says "find the y coordinate if x = -4" yet underneath if appears they want x = -6 !
If x = -6
Substitute -6 into the equation in place of x
⇒ y = 1 × (-6)² + 3(-6)
Apply the rule (-a)² = a² and a(-b) = -ab:
⇒ y = 1 × (6)² + -3×6
⇒ y = 1 × 36 + -18
Using order of operations, carry out the multiplication first:
⇒ y = 36 + -18
Then the addition (subtraction)
⇒ y = 36 - 18
⇒ y = 18

Hypotenuse
→ Identify a formula without hypotenuse in it
T = O ÷ A
→ Rearrange formula to find assigned length
Opposite = Tan ÷ Adjacent
→ Substitute in the numbers
tan ( 43 ) ÷ 56 = 52.22
What is the answer
Answers
Answer:
B
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
Given the following arithmetic sequence; starting with 107, which term has a value of -61?
107, 101, 95...-61
(show steps pls)
Answers
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.

Answer:
a. geometric
b. an = 2(2)^n-1 or an = 2^n
c. an+1 = an x 2
Step-by-step explanation:
The sequence, 2, 4, 8, 16, 32,...
a. The sequence is geometric because there is a common ratio in the numbers of the sequence. Each number is made by multiplying the common ratio and the previous number.
b. The explicit formula that can be used to find any term is an = 2(2)^n-1 or an = 2^n
Note: the variable n and number 1 is written in italics to show that it should be in subscript
an = a1 (r)n-1
With the common ratio of n being 2 and first number being 2, we have:
an = 2(2)^n-1
or
an = 2^n
c. The recursive formula for the sequence is an+1 = an x 2
an+1 = an x r
Plugging in the values, we have
an+1 = an x 2

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
Answers
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:
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)

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

For any real numbers a and b, if a/b = 1, then a = b. This means
