Answer:
Fifth Day (1024 pounds)
Step-by-step explanation:
For every subsequent day, he collected 4 times the previous day.
This increase is a ratio/product, therefore the sequence is a geometric sequence.
The nth term of a geometric sequence,
Where:
a=first term
r=common ratio
n=number of terms
Corey collected 4 pounds of newspaper on day 1., a=4
After day one he collected 4 times the amount and for every subsequent day, he collected 4 times the previous day. r=4
We want to determine on which day he will first collect over a 1000 pounds of new paper.
In order to apply law of indices, we look for the next term greater than 250 which is an index of 4.
Therefore on the fifth day, he will collect an amount over 1000 pounds, precisely 1024 pounds.
Write an equation for the line in slope-intercept form.
Answer:
y = –3x – 6
Step-by-step explanation:
We'll begin by obtaining the slope of the equation y = –3x – 2.
This can be obtained by comparing
y = –3x – 2 with y = mx + c
Thus, the slope (m) of the equation
y = –3x – 2 is –3.
Next, we shall determine the slope of the equation parallel to line with equation y = –3x – 2.
This is illustrated below:
For parallel lines, the slope are related as follow:
m1 = m2
m1 = –3
m2 = m1 = –3.
Finally, we shall determine the equation as follow:
Coordinate = (–3, –3)
x1 coordinate = –3
y1 coordinate = –3
Slope (m) = –3
y –y1 = m(x – x1)
y – (–3) = –3 (x – (–3))
y + 3 = –3 (x + 3)
y + 3 = –3x – 3
Rearrange
y = –3x – 3 – 3
y = –3x – 6
Thus, the equation parallel to the line is y = –3x – 6
The value of x is for the given trigonometric function is found as: x = 0.1303 + 1/15 *2nπ.
The given expression is:
16 cos(15x) + 8 = 2
On simplification:
cos(15x) = (2-8)/16
cos(15x) = -3/8
15x = arcos ( -3/8 )
15x = 2π - arcos ( -3/8 )
15x = arcos ( -3/8 ) + 2nπ ;or
15x = 2π - arcos ( -3/8 ) + 2nπ ; n ∈ Z
So,
15x = 1.955 + 2nπ
x = 1/15(1.955 + 2nπ)
x = 0.1303 + 1/15 *2nπ , n ∈ Z
Thus, the value of x is found as: x = 0.1303 + 1/15 *2nπ.
