How many terms are in the polynomial 10x^2 + 5x - 11

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)

__

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

__

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

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]

Answer:

This is a vertical angle theorem

Step-by-step explanation:

Vertical angles are a pair of opposite angles formed by intersecting lines. In the figure, ∠1 and ∠3 are vertical angles. ... Vertical angles are always congruent . So, in this figure, ∠1≅∠3 and ∠2≅∠4 .

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)

Answer:

3/5

Step-by-step explanation:

Cosine of A is adjacent/hypotenuse. The side adjacent to A is 18, and the hypotenuse is 30. 18/30 can be reduced to 3/5 by dividing the numerator and denominator by 6.

Hope this helps!

Answer:

y=13

Step-by-step explanation:

The pythagoram theorm states that a^2+b^2=c^2, c being the hypotenus

If we input the values from the triangle we get the equation

12^2+5^2=y^2

simplify

144+25=Y^2

169=y^2

To get the value of y, take the root of both sides

√169=√y^2

13=y

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

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.
