Dima020 [189]2 years ago
5 0

Answer:

no

Step-by-step explanation:

14:8 = 14/8 = 7/4

28:10 = 28/10 = 14/5

PLS HELP. Find the first four terms of the recursive sequence defined by the following formula:
Gnoma [55]

Answer:

see explanation

Step-by-step explanation:

Given the recursive formula a_{n} = \frac{a_{n-1} }{4} and

a_{4} = 2 \frac{1}{4} = \frac{9}{4}, then

\frac{a_{3} }{4} = \frac{9}{4} ( multiply both sides by 4 )

a₃ = 4 × \frac{9}{4} = 9

\frac{a_{2} }{4} = 9 ( multiply both sides by 4 )

a₂ = 36

\frac{a_{1} }{4} = 36 ( multiply both sides by 4 )

a₁ = 144

The first 4 terms are

144, 36, 9, 2 \frac{1}{4}

What is the y-intercept of the line represented by y = 4x?​
Brut [27]

Answer: 0

Step-by-step explanation: In order to identify the <em>y-intercept</em> of this equation, we want to get this equation into slope-intercept form which is more commonly known as y = mx + b form.

The problem is our equation doesn't match up quite so well with the formula y = mx + b. Our slope or <em>m</em> which is represented by the coefficient of the <em>x</em> <em>term</em> is clearly +4 but what is our y-intercept or b?

Well y = 4x can be thought of as y = 4x + 0 so you can see that our b or y-intercept equals 0.

If 0.5% of a number is 250, find the number
kaheart [24]

0.5% or 1/2% of say "x" is 250, whilst "x" is the 100%.

\begin{array}{ccll} \%&amount\\ \cline{1-2} \frac{1}{2}&250\\[1em] 100&x \end{array}\implies \cfrac{~~ \frac{1}{2}~~}{100}=\cfrac{250}{x}\implies \cfrac{1}{200}=\cfrac{250}{x}\implies x = 50000
