Answer:
90
Step-by-step explanation:
The first term = 6* 2^0 = 6
The second term = 6 * 2^ (2-1) = 6*2 = 12
The third term = 6* 2^(3-1) = 6*2^2 = 6*4 = 24
The fourth term = 6* 2^(4-1) = 6* 2^3 = 6*8 = 48
S4 is the sum of the 1st four terms
S4 = 6+ 12+24+ 48 = 90
8)
is -0.896 radians
9) length of arc is 41.91 cm
Solution:
8)
Given that,

is in quadrant 4
To find: 
From given,

Thus value of
is -51.34 degrees
Convert degrees to radians

Thus
is -0.896 radians
9)
From given,
radius = 15.4 cm

<em><u>The length of arc when angle in radians is:</u></em>

Thus length of arc is 41.91 cm
Answer:
$1.69
Step-by-step explanation:
Half a dollar = $0.50
Eight dimes = $0.80
Six nickels = $0.30
Nine pennies = $0.09
Total = $0.50 + $0.80 + $0.30 + $0.09 = $1.69

Answer:
x = √76
Step-by-step explanation:
in upper triangle :
7² - 3² =40 so the third side of the upper triangle is : √40
in the biggest triangle :
(3+3)² + 40 = 76 so the another side of the biggest triangle is : √76
