Answer:
a) -2/5
b) No sum
Step-by-step explanation:
The sum will only exist if the magnitude of the base is less than 1. For first term a1 and common ratio r, the infinite sum is ...
S = a1/(1 -r)
__
a)The first term is -2/3, and the common ratio is -2/3. The infinite sum is ...
S = (-2/3)/(1 -(-2/3)) = (-2/3)/(5/3) = -2/5
__
b)The common ratio (-4) has a magnitude larger than 1. There is No Sum.

Additional comment
The "infinite sum" of the first series can be calculated by most calculators using fewer than 100 terms. The 100th term will have a value on the order of 2.5×10^-18, so will be beyond the ability of most calculators with 16-digit precision to properly add it to the sum. The attachment shows the output from one such calculator.
As we see from the above sum formula, for rational values of a1 and r, the resulting sum will be a rational number. Often, there will be little error by having a calculator compute the "exact" value of the infinite sum using a suitable finite-length series. Some calculators may be more trustworthy than others in this regard. YMMV

y = x -4
y = -x + 6
What is the solution for this system of equations?
(1,5)
(6, – 4)
(-4, 6)
(5, 1)
Step-by-step explanation:
y = x - 4
y = -x + 6
x - 4 = -x + 6
x + x = 6 + 4
2x = 10
x = 10/2 = 5
y = x - 4
y = 5 - 4
y = 1
Solution = (5,1)

what are the zeros of the polynomial function ? f(x) = 2x (x-2) (1-x)
Answer:
The zeros are 0 ,2, and 1
Step-by-step explanation:
f (x) = 2x (x - 2) (1 - x)
set f(x) equal to y
y = 2x (x - 2) (1 - x)
solve when y is 0 because when y is 0 then it is an x-intercept
0 = 2x (x - 2) (1 - x)
separate all of the equations out
0 = 2x
0 = (x - 2)
0 = (1 - x)
solve for x for each equation
0 = 2x
divide both sides by 20/2 = 0 and 2x/2 = x0 = xx = 00 = (x - 2)
add 2 to both sides0 + 2 = 2 and (x - 2) + 2 = x2 = xx = 20 = (1 - x)
subtract 1 from both sides0 - 1 = -1 and (1 - x) - 1 = -x-1 = - xmultiply both sides by -1-1 · -1 = 1 and -x · -1 = x1 = xx = 1I need help fast plz

9 3/10 - 5 3/4 as a mixed number in simplest form
Answer:
71/20 or 3 [tex]\frac{11}{20}[/tex]
Step-by-step explanation:
→ 9 [tex]\frac{3}{10}[/tex] = 9 * 10 + 3 / 10
9[tex]\frac{3}{10}[/tex] = 93/10
→ 5 [tex]\frac{3}{4}[/tex] = 5 * 4 + 3 / 4
5 [tex]\frac{3}{4}[/tex] = 23/4
Making the denominators alike;
93 * 4/ 10 * 4 = 372/40
23 * 10 / 4 * 10 = 230/40
93/10 - 23/4 = 372/40 - 230/40
= 142/40
= 71 / 20 (simplifying by dividing both by 2) OR 3 [tex]\frac{11}{20}[/tex]

Find the value of t and u.
Answe xplanation:
You can treat x and 2x+1 just as though they are real numbers.
So f(2x+1) = 3(2x+1) - 5 = 6x + 3 - 5 = 6x - 2
In the above, I made use of something called the distributive law which says that if a,b and c are real numbers, then a(b+c) = ab + ac. pls get it in here

the diagonals of a rhombus are 16 cm and 12cm. find its length
Answer:
l=10 cm
Step-by-step explanation:
In a rhombus, the diagonals are cut into identical lines at the intersection.
This way, I found the measures of the halves of the diagonals in a right triangle, knowing that the diagonals of the rhombus are perpendicular on each other.
I calculated that AO = AC/2= 8, and that BO=BD/2= 6, and then I applied pytagora's theorem in a quarter of the rhombus, which is the right triangle AOB, to find the length of a side

Answer:
The sector for 126 rubies would measure 126 degrees.
Step-by-step explanation:
First, a pie-chart is a circle, and there are 360 degrees in a circle. Because there are 320 total gemstones, 1 gemstone maps to 1.125 degrees. That is, 1.125 degrees per gemstone.
[tex]360\div320=1.125[/tex]
Knowing that, you can calculate the degrees in the pie-chart for any given number of gemstones. Just multiply the gemstones by 1.125.
[tex]112\times1.125=126[/tex]
The sector for 112 rubies would measure 126 degrees.
If you want to be extra sure, you can calculate that for all types of gemstones and add them up:
[tex]32\times1.125=36\\112\times1.125=126\\96\times1.125=108\\64\times1.125=72\\16\times1.125=18\\36+126+108+72+18=360[/tex]
That confirms they all add up to 360 degrees.

Ann works as a tutor for $9 an hour and as a waitress for $8 an hour. This month, she worked a combined total of 94 hours at her two jobs.
Lett be the number of hours Ann worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month.
Answer:
Ann earned $752+x in a month
If you take t as hours he worked as tutor then ,
Money earned will be $752+t
Answer:
earnings = 752 +t
Step-by-step explanation:
If Ann worked t hours as a tutor, then she worked (94-t) hours as a waitress. Her total wages were ...
earnings = waitress wages + tutor wages
earnings = 8(94 -t) + 9(t)
earnings = 752 +t . . . . . . . simplify

Write a function that represents the relationship between X and y shown in the graph below
Answer:
y = 3x - 10
Step-by-step explanation:
Find the slope of the line by calculating the Rise/Run between any two points. I picked (-2,-16) and (4,2).
The Rise is = (2-(-16))=18
The Run is = (4 -(-2)) = 6
Rise/Run is 18/6 = 3. The slope is three:
y = 3x + b
b is the y-intercept, the value of y when x=0. b is - 10 in this graph.
y = 3x - 10 is the line of this graph.
