Citrus2011 [14]2 years ago
5 0

Answer:

y = 2.5x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2.5 and c = - 8 , then

y = 2.5x - 8 ← equation of line

Find the 6th term of a geometric sequence with t1=5 and r = -1/2
Hoochie [10]
In this item, we are to calculated for the 6th term of the geometric sequence given the initial value and the common ratio. This can be calculated through the equation,
   
                 An = (A₀)(r)ⁿ ⁻ ¹ 
where An is the nth term, A₀ is the first term (in this item is referred to as t₀), r is the common ratio, and n is the number of terms. 

Substitute the known values to the equation,

                   An = (5)(-1/2)⁶ ⁻ ¹
                   An = -5/32

Hence, the answer to this item is the third choice, -5/32.

2. Let's pretend I'd give you a penny today, two pennies
gizmo_the_mogwai [7]
Answer:
-f(n+1) = f(n) x 2
-on the 10th day you'd receive $512
-this function works by taking the output of the last input and multiplying it by 2 to find the new output.
-i'd rather take 40 days of this money scheme.

example of use:
f(10) = f(9) x 2
output of f(9) is 256 so f(10) = 256 x 2

Help me with these questions circled
Vaselesa [24]
61.

40 ==> 100 %
x   ==> 15 %

15*40/100 = 6.

Therefore, merely 6 students received C grades.

62.

23 500 ==> 100%
x          ==> 42 %

42*23500/100 = 9870

Therefore 9870 people in the town are over 45 years of age.

You continue wth this method and you'll find for the 63, 64, 65.

In maths, you have to understand what you're doing dude ^^.

Whatever the answer for 64 and 65 are 

64.

21.50*20/100 = 4.3

65. 

250 ==> 100 %
45 ==> x %

x = 45*100/250 = 18 %

i will let you do the 63 alone, give me what you have found in the comments, i'll verify your answer.

Hope this helps !
