Answer:
34
Step-by-step explanation:
The angle x^2 + (x+12) + 100 will need to equal 180.
Therefore, set your formula
180 = 100+(x+12)+x
180 = 100+2x+12
180-100-12=2x
68=2x
68/2 = x
34 = x

Answer:
[tex]a_n_+_1 = a_n + 6[/tex]
Step-by-step explanation:
Recursive equations use the previous term as a base for the next. Because of this, the left side of the equation needs to be a representation of the next term. The right side of the equation consists of the current term plus, minus, times, or divided by a certain number. Therefore, your answer here is [tex]a_n_+_1 = a_n + 6[/tex].

a^2 - 2a+1/6 divided by (a^2-1)= _________
The denominator of the resulting fraction is

→6(a + 1)

Answers
9514 1404 393
Answer:
(b) 6(a+1)
Step-by-step explanation:
Common factors are cancelled from numerator and denominator.
[tex]\displaystyle\frac{a^2-2a+1}{6}\div(a^2-1)=\frac{(a-1)^2}{6}\cdot\frac{1}{(a-1)(a+1)}\\\\=\frac{(a-1)(a-1)}{6(a-1)(a+1)}=\boxed{\frac{a-1}{6(a+1)}}[/tex]
The denominator of the result is 6(a+1).
(cosA+cosB)²+(sinA+sinB)²=4cos²(A-B/2)
Answers
LHS = (cosA+cosB)²+(sinA+sinB)²
= (cos²A+2cosAcosB+cos²B)+
(sin²A+2sinAsinB+sin²B)
/* By algebraic identity:
(x+y)² = x²+2xy+y² */
Rearranging the terms, we get
= (cos²A+sin²A)+(cos²B+sin²B)+2(cosAcosB+sinAsinB)
= 1+1+2cos(A-B)
________________________
we know that,
i) cos²x + sin²x = 1
ii) cosxcosy+sinxsiny = sin(x-y)
________________________

Therefore,

Given the three sides of a triangle, classify
the triangle as acute, right, or obtuse.
11, 7, 4
A. acute
B. right
C. obtuse
Answers
Answer:
acute
Step-by-step explanation:
Given the 3 sides of a triangle a, b, c ( where c is the longest )
• If a² + b² = c² ⇒ right triangle
• If a² + b² > c² ⇒ acute angled triangle
• If a² + b² < c² ⇒ obtuse angled triangle
Here a = [tex]\sqrt{11}[/tex], b = [tex]\sqrt{7}[/tex] , c = 4
c² = 4² = 16
a² + b² = ([tex]\sqrt{11}[/tex] )² + ([tex]\sqrt{7}[/tex] )² = 11 + 7 = 18
Since a² + b² > c² then triangle is acute
whats the equation for this please help
Answers
Answer:
y = ⅓ x² - 3
Step-by-step explanation:
---------------
[tex]y = \frac{1}{3} {x}^{2} - 3[/tex]
Step-by-step explanation:
The general vertex form of the equation is
[tex]y = a {(x - h)}^{2} + k[/tex]
where (h, k) are the coordinates of the vertex and a is a constant. In your case, the vertex is located at (0, -3) so your equation becomes
[tex]y = a {x}^{2} - 3[/tex]
To find a, substitute the point (3, 0) into the equation
0 = a(3)^2 - 3 ---> a = 1/3
Therefore, the equation has the form
[tex]y = \frac{1}{3} {x}^{2} - 3[/tex]

Find the x- and y-intercept of the line.
2x + 3y = -18
Answers
Hi there!
»»————- ★ ————-««
I believe your answer is:
X - Intercept: (-9, 0)
Y - Intercept: (0, -6)
»»————- ★ ————-««
Here’s why:
The x and y-intercepts of a line is where a given function intercepts the x or y axes.
I have graphed the equation given on a program. The graph shows that the line passes through the points (0, -6) and (-9, 0).
Therefore:
[tex]\rightarrow\text{The x-intercept of the given equation is }\boxed{\text{(-9,0)}}.\\\\\rightarrow\text{The y-intercept of the given equation is }\boxed{\text{(0,-6)}}.[/tex]
See the graph attached below!
»»————- ★ ————-««
Another way to solve this problem is to do this algebraically.
[tex]\text{X-Intercept: Substitute the 'y' variable for zero and solve for 'x'.}\\\\2x + 3y = -18\\-------\\\rightarrow2x+3(0)=-18\\\\\rightarrow2x=-18\\\\\rightarrow\frac{2x=-18}{2}\\\\\rightarrow\boxed{x=-9}\\-------\\\boxed{\text{X-Intercept: (-9,0)}}[/tex]
----------------------------
[tex]\text{Y-Intercept: Substitute the 'x' variable for zero and solve for 'y'.}\\\\2x+3y=-18\\\-------\\\rightarrow2(0)+3y=-18\\\\\rightarrow3y=-18\\\\\rightarrow\frac{3y=-18}{3} \\\\\rightarrow\boxed{y=-6}\\\-----\\\\\boxed{\text{Y-Intercept: (0,-6)}}[/tex]

Which statement best describes the sequence defined by ?
The series diverges because it has a sum of 6.
The series converges because it has a sum of 3/4.
The series converges because it has a sum of 2.
The series diverges because it does not have a sum.
Answers
Answer:
well its not c so...
Step-by-step explanation:
that'll leave you w 3 others to choose from. sorry.
The series diverges because it does not have a sum option, fourth is correct.
What is the convergent of a series?A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums get closer and closer to a certain number.
We have an infinite series:
[tex]\rm \sum ^{\infty}_{n=1}\dfrac{3}{4}(2)^n[/tex]
[tex]\rm \sum ^{\infty}_{n=1}3(2)^{n-2}[/tex]
The above series is geometric series with first term 2 and the common ratio is 2.
Here 2>1
By the ratio test, the series is divergent.
Since the common ratio is greater than 1 the sum will be infinite.
Thus, the series diverges because it does not have a sum option, fourth is correct.
