A(1) = - 3 ;
a(2) = a(1) + ( 2 - 1 )d ;
3 = -3 + d ;
d = 6 ;
a(3) = a(1) + ( 3 - 1)d;
9 = - 3 + 2d ;
12 = 2d ;
d = 6 ;
a(4) = a(1) + ( 4 - 1 )d ;
15 = -3 + 3d ;
18 = 3d ;
d = 6 ;
Then, a(n) = - 3 + ( n- 1 )6 ;
a(n) = - 3 + 6n - 6 ;
a(n) = 6n - 9 is an explicit functin rule for the sequence -3, 3, 9, 15, ...
Answer:
125
Step-by-step explanation:
1,000/8 because all the outcomes are evenly likely
Answer: -43.3
Step-by-step explanation:
We will use the order of operations, sometimes called PEMDAS. <em>See attached for more information on this subject</em>.
Given:
8.7 - (1 + 3)³ + 6 · 2
Simplify parentheses:
8.7 - (4)³ + 6 · 2
Raise to the power of three:
8.7 - 64 + 6 · 2
Multiply:
8.7 - 64 + 12
Subtract:
-55.3 + 12
Add:
-43.3
Answer:
115°
Step-by-step explanation:
< SPQ = < QRS ( being opposite angles of parallelogram)
<SPQ = 115°
Hope it will help. ❤
The required expression will therefore be:
(3×18) + (5×6) + 4
Her total score is 88points :
From the question given, we are told that Samantha scored 3 points for each of 18 multiple choice questions, this means that the total points made here is expressed as:
(3 × 18) ...1
If she got 5 points for each of the 6 short response questions she answered
correctly, the total point made will be expressed as;
(5×6) ... 2
Total score for an additional 4 points for the bonus question will be "4"
Expression for her total score will be the sum of all the expression above as thus:
(3×18) + (5×6) + 4
Taking the sum, her score will be:
= (3×18) + (5×6) + 4
= 54 + 30 + 4
= 84 + 4
= 88 points
The required expression will therefore be:
(3×18) + (5×6) + 4
Her total score is 88points
