Which values represent the first two terms of the sequence a1=2 and an=-4(an-1)^2?

cricket20 [7]

<span>a1= (which is the first term.)
to find the 2nd term you plug in 2 for (an) in the formula given to you. =-4(2-1)^2 *remember an represents the term u are looking for *
now you start to solve it
-4(2-1)^2
-4 (1)^2 .
-4^2 = 16
so your first two terms are 2 and 16 .</span>

What is the value for y?<br> Enter your answer in the box.<br> y=

serious [3.7K]

Answer:

$y =112$

Step-by-step explanation:

Given

The attached triangle

Required

Find y

The attached triangle is isosceles; so:

$x - 5=34$

Also, we have:

$y + x - 5 + 34=180$ --- angles in a triangle

Substitute: $x - 5=34$

$y + 34 + 34=180$

Collect like terms

$y =- 34 - 34+180$

$y =112$

how many kilograms of pure water is to be added to 100 kilograms of a 30% saline solution to make it a 10% saline solution

Irina-Kira [14]

Answer:

200 kg

Step-by-step explanation:

If w is the amount of water added, then the concentration of the solution is ...

salt/solute = 100(0.30)/(100 +w) = 0.10

30 = 10 +0.10w . . . . . simplify

20 = 0.10w . . . . . . . . subtract 10

20/0.10 = w = 200 . . . . divide by 0.10

200 kg of water must be added to dilute the solution to 10%.

In 1990 the average family income was about $ 39 , 000 , and in 2010 it was about $ 70 , 768 . Let x = 0 represent 1990, x = 1 r

iren2701 [21]

Answer:

<em /> $f(x) = 1588.4x + 39000$ <em />

$f(15) = 62826$

Step-by-step explanation:

Given

In 1990; Income= $39000

In 2010; Income= $70768

Solving (a): An equation in form of f(x) = ax + b

First, we need to determine the slope, a

$a = \frac{y_2 - y_1}{x_2 - x_1}$

Taking y as income and x as year index.

When x = 0; y = 39000

When x = 20; y = 70768

Substitute these values in the above formula

$a = \frac{70768 - 39000}{20 - 0}$

$a = \frac{31768}{20}$

$a = 1588.4$

Next, is to determine the formula using:

$y - y_1 = a(x - x_1)$

<em>Considering :When x = 0; y = 39000, we have</em>

<em /> $y - 39000 = 1588.4(x - 0)$ <em />

<em /> $y - 39000 = 1588.4x$ <em />

<em>Make y the subject of formula</em>

<em /> $y = 1588.4x + 39000$ <em />

<em />

<em>Express y as a function of x</em>

<em /> $f(x) = 1588.4x + 39000$ <em />

Solving (b): Income in 2005

<em>In 2005, x = 15</em>

So:

$f(x) = 1588.4x + 39000$ becomes

$f(15) = 1588.4 * 15 + 39000$

$f(15) = 62826$
