Please help me right now.

spin [16.1K]

$\sum\limits_{k=1}^{\infty}12\left(0.7\right)^{k-1}$

The infinite geometric series is converges if |r| < 1.

We have r = 0.7 < 1, therefore our infinite geometric series is converges.

The sum S of an infinite geometric series with |r| < 1 is given by the formula :

$S=\dfrac{a_1}{1-r}$

We have:

$a_1=12(0.7)^{1-1}=12(0.7)^0=12\\\\r=0.7$

Substitute:

$S=\dfrac{12}{1-0.7}=\dfrac{12}{0.3}=40$

Answer: c. Converges, 40.

Answer:

140°

Step-by-step explanation:

$\because m\widehat{BG} = 360\degree - m\widehat{GCB} \\\therefore m\widehat{BG} = 360\degree - 300\degree \\\therefore m\widehat{BG} = 60\degree \\\because m\widehat{BGD} = m\widehat{BG} +m\widehat{GD}\\\therefore m\widehat{BGD} = 80\degree+60\degree\\\therefore m\widehat{BGD} = 140\degree\\\because m\angle BAD = m\widehat{BGD} \\\huge\purple {\boxed {\therefore m\angle BAD =140\degree}}$

Oxana [17]

Answer:

d. (-14) + (-8)

a. (-14) + 8

Step-by-step explanation:

(-14) - 8 is equal to (-14) + (-8) because we still add two negative values so the result wouldn't change.

(-14) - (-8) is equal to (-14) + 8 because there's two negative sign in front of 8 and two negative values multiplied makes a positive result.
