<u>Answer:</u>
100
<u>Step-by-step explanation:</u>
Given :
Terms ( n ) = 100
First term ( a ) = 100
Series = > 100 + 98 + 96 .......
Common difference ( d ) = 98 - 100 = > - 2
We know sum formula:
S_n = ( n / 2 ) ( 2 a + ( n - 1 ) d )
= > S_100 = ( 100 / 2 ) ( 200 + ( 100 - 1 ) - 2 )
= > S_100 = 50 ( 200 - 198 )
= > S_100 = 50 ( 2 )
= > S_100 = 100
Therefore, sum of first 100 terms is 100.
2 (x + 2) + 2 (7) = 32
2x + 4 + 14 = 32
2x + 18 = 32
2x = 32 - 18
2x = 14
2x ÷ 2 = 14 ÷ 2
x = 7
y = 8.6 * cos(44.25)=
6.1602
Rounded to nearest hundredth = 6.16

The answer is
<h2>

</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question
slope / m = 4/7
y intercept / c = 3
Substitute the values into the above formula
We have the equation as

<u>Answer:</u>
1.95 cubic feet
<u>Step-by-step explanation:</u>
We are given that Emily stores her jewelry in a cube and the cube has a side length of
feet.
feet in an decimal form is 1.25 feet.
We know that,
<em>volume of a cube = s
</em>
where <em>s</em> is the side length of the cube.
So substituting this value of side length of cube in the formula to get:
Volume of cube =
= 1.95 feet
