The sequence below shows a certain company's expected net worth, in millions of dollars, after 1, 2, 3, and 4 years (and so on). 14.5, 13.1, 11.7, 10.3,...
Which function models the nth
term of this sequence, for n = 1, 2, 3, 4, ...?
A
B
f(n) = 14.5 – 1.4(n − 1)
f(n) = 14.5 + 1.4(n − 1)
f(n) = 14.5 – 1.4n
f(n) = 14.5 + 1.4n
D

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
