Answer:

Step-by-step explanation:

It is one of the two sums that go to infinity. The other two will end in some sort of sum even though r is > 1 in D and < -1 in B. The answer will likely be quite nasty in both of them, still they will end somewhere.

That leaves with A and C.

A: will converge somewhere - 1 <r <1 converges when that condition about r is true and you can get a sum.

C the one that does not converge anywhere. 4/3 raised to a large power gives a very large number which never gets smaller and the sum is indefinite getting larger and larger as i increases. C is your answer.

Answer:

a) acute angle

b) obtuse angle

c) right angle

d) reflex angle

e) straight line angle

f) acute angle

Step-by-step explanation:

Acute angle

angle that is smaller than 90°
0° < θ < 90°

Right angle

angle that is 90°
shaped of a "L"

Obtuse angle

angle that is greater than 90° but smaller than 180°
90° < θ < 180°

Straight line angle

angle that is 180°
drawn in a straight line

Reflex angle

angle than is greater than 180°
θ > 180°

What number must you add to complete the square x^-8x=39

notsponge [240]

Answer:

Given equation: $x^2-8x =39$

when we complete the square , we take half of the value of 8 , then square it, and added to the left sides, we get;

$x^2-8x+4^2 = 39 +4^2$

∵8 is the value $(\frac{8}{2})^2$

Notice that, we add this both sides so that it maintains the equality.

then;

$x^2-8x+4^2 = 39 +4^2$

$(x-4)^2 = 39 + 16$ [ $(a-b)^2 = a^2-2ab+b^2$ ]

Simplify:

$(x-4)^2 =55$

The number must be added to complete the square is, $4^2 = 16$

A line passes through 2, -1 and 4, 5 what is the equation

SVEN [57.7K]

y1 - y2 / x1 - x2

-1 - 5 / 2 - 4

-6/-2

y = mx + b

-1 = 3(2) + b

-1 = 6 + b

-7 = b

y = 3x - 7

Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> 500(1.075)120x = 100.000

Volgvan

Answer:

The solution is:

$x = 0.61$

Step-by-step explanation:

The first step to solve this equation is placing everything with the exponential to one side of the equality, and everything without the exponential to the other side. So

$500(1.075)^{120x} = 100000$
