Find the 7th term of the arithmetic sequence given a12=29 and
a16=53
ara
Answer:
a7=-1
Step-by-step explanation:
Arithmetic Sequences
The arithmetic sequences can be identified because each term n is obtained by adding or subtracting a fixed number to the previous term n-1.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
We know: a12=29, a16=53, now we use the above equation for n=12 and n=16:
[tex]a_1+(12-1)r=29[/tex]
[tex]a_1+(16-1)r=53[/tex]
Simplifying both equations:
[tex]a_1+11r=29[/tex]
[tex]a_1+15r=53[/tex]
Subtracting:
[tex]4r=53-29=24[/tex]
Solving:
r=24/4
r=6
The 7th term can be found as 9 terms before the 16th:
[tex]a_7=a_{16}-9r[/tex]
[tex]a_7=53-9*6=53-54=-1[/tex]
Thus: a7=-1

which equation is y=(x+3)^2+(x+4)^2 rewritten in vertex form?
Answer:
[tex]y-1/2=2(x+7/2)^2[/tex]
Step-by-step explanation:
Equation of the Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y-k=a(x-h)^2[/tex]
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The given function is:
[tex]y=(x+3)^2+(x+4)^2[/tex]
Expanding the squares:
[tex]y=x^2+6x+9+x^2+8x+16[/tex]
Simplifying:
[tex]y=2x^2+14x+25[/tex]
Factoring 2 from the first two terms:
[tex]y=2(x^2+7x)+25[/tex]
The expression in parentheses must be completed to form the square of a binomial:
[tex]y=2(x^2+7x+49/4-49/4)+25[/tex]
Isolating the square of the binomial:
[tex]y=2(x^2+7x+49/4)-49/2+25[/tex]
Operating and Factoring:
[tex]y=2(x+7/2)^2+1/2[/tex]
Rearranging:
[tex]\boxed{y-1/2=2(x+7/2)^2}[/tex]
Comparing with the vertex form:
a=2, h=-7/2, k=1/2

In the function above, the slope will be multiplied by -9, and the y-value of the y-intercept will be increased by 2 units. Which of the following graphs best represents the new function? if u need the choice ill give them to u
Answer:
Step-by-step explanation:
I can give you the key points to look for without the graph. You'll have to do that.
New y intercept
The intercept increases by 2. Currently it is 2. The new y intercept is 2 + 2 = 4
The new Slope
The slope is multiplied by - 9. Currently it is (y2-y1)/(x2 - x1) = (2-0)/(0-6) = 2/-6= - 1/3
This is multiplied by - 9
-9*(-1/3) = 3
New equation
y = 3x + 4
x intercept.
The x intercept occurs when y = 0.
0 = 3x + 4
-4 = 3x
-4/3 = x

Rebecca writes 1/5 of a page in 1/14 minute. How many pages can she write in one minute? (fraction) pages per minute.
Answer:
She can write 2 pages and 4/5 extra.
Step-by-step explanation:
What you're going to do is multiply 14 by 1/5.
14/1 x 1/5 = 14/5
14/5 = 2 4/5

What is required of a proportional relationship that is not required of a general line relationship?
Answer:
Step-by-step explanation:
Pertains to y-intercept is then 0.
It introduces the relationship between two variables and is called correlation. Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)
If you are given the length of the hypotenuse and one leg, does it matter whether you solve for a or b? Explain.
Answer:
No because [tex]a^2 + b^2 = b^2 + a^2[/tex]
Step-by-step explanation:
No it does not matter if you were given a or b because with the equation a²+b²=c² as long as you can substitute in two values you can solve for the unknown value. For example if you had triangle STU having hypotenuse as 41 and value a as 9 you would substitute in the values resulting in the equation 9²+b²=41² then you would solve the exponents 81+b²=1681 then you would subtract 81 having the equation now as b²=1600 then you would √b²=√1600 resulting in
b=40
you could solve that equation the same way if you had b=40 and c=42

Answer:
∠ 1 = 149°, ∠ 2 = 31°
Step-by-step explanation:
∠ 1 and 31° are same-side interior angles and are supplementary, thus
∠ 1 = 180° - 31° = 149°
∠ 2 and 31° are alternate angles and congruent, thus
∠ 2 = 31°

Solve v +8 <3 or 8v <-40.
[tex]v + 8 < 3[/tex]
Subtract sides -8
[tex]v + 8 - 8 < 3 - 8[/tex]
[tex]v < - 5[/tex]
_________________________________
[tex]8v < - 40[/tex]
Divided sides by 8
[tex] \frac{8}{8}v < \frac{ - 40}{8} \\ [/tex]
[tex]v < - 5[/tex]
_________________________________
Done.... ♥️♥️♥️♥️♥️
The solution of the given inequality v +8 <3 or 8v <-40 is v < -5.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
A mathematical phrase in which the sides are not equal is referred to as being unequal.
Given the inequality,
v +8 < 3
Adding -8 on both sides
v + 8 - 8 < 3 - 8
v < -5
Or,
8v <-40
Divide 8 on both side
v < -5
Hence "The solution of the given inequality v +8 <3 or 8v <-40 is v < -5".
