<em>Greetings from Brasil...</em>

See the attached figure. The smaller the θ angle, the smaller the AB side will be. If the angle θ = 90º, then AB = 25. As θ < 90, then AB < 25

5X - 10 < 25

5X < 25 + 10

X < 35/5

X < 7

The AB side can be neither zero nor negative. So

5X - 10 > 0

5X > 10

X > 10/5

X > 2

What is the sum of the infinite geometric series 1 - 1/2 + 1/4 - 1/8 + 1/16

mina [271]

Answer: The answer is 11/16

Step-by-step explanation:

PEMDAS theres only addition and subtraction so we figure out this equation left to right.

1-1/2=1/2

1/2+1/4=3/4

3/4-1/8=5/8

5/8+1/16=11/16

I need help like RN!!!<br> what are the foci of the ellipse? graph the ellipse. 18x^2+36y^=648

Thepotemich [5.8K]

Hi,

$18x^2+36y^2=648\\

\Rightarrow ( \dfrac{x}{6})^2+( \dfrac{y}{3* \sqrt{2} } )^2=1\\

a=6,\ b=3* \sqrt{2}\\

c= \sqrt{a^2-b^2} = \sqrt{36-18} =3* \sqrt{2}\\

$
Center is (0,0)
Foci are (-3√2,0) and (3√2,0)

A ball is kicked into the air and follows the path described by h(t)= – 4.9t^2 + 6t + 0.6, where t is the time in seconds and h

miv72 [106K]

The maximum value can be determined by taking the derivative of the function.

(dh/dt) [h(t)] = h'(x) = -9.8t + 6

Set h'(x) = 0 to find the critical point

-9.8t + 6 = 0
-9.8t = -6
t = 6/9.8

Plug the time back into the function to find the height.

h(6/9.8) = -4.9(6/9.8)^2 + 6(6/9.8) + .6
= 2.4

And I don't understand your second question.

VashaNatasha [74]

Ahmad = 1/6
Barry = 1/2
Tara = 1 - 1/6 - 1/2 = 1/3

1/3 of the seashells = 76
3/3 of the seashells = 76 x 3
3/3 of the seashells = 228

----------------------------------------------------------------------------
Answer: They had 228 seashells altogether.
