What is true of the function g(x)=-2x^2+5?

astraxan [27]

Answer:

Step-by-step explanation:

Next time, please try to make your question more specific.

g(x)= -2x^2+5 is a modification of f(x) = x^2 (a parabola with vertex at (0, 0) and opening up).

If f(x) = x^2 is graphed, we can translate its shape up, down, right or left.

In g(x)= -2x^2+5, this graph has been translated up by 5 units, inverted (so that it now opens down), and vertically stretched by a factor of 2.

David takes out a 20year 70,000 loan from his bank 2010. The quadratic equation that approximates the year/loan balance relation

konstantin123 [22]

Answer:

2022

Step-by-step explanation:

The duration of the loan David takes = 20 year loan

The amount David takes as loan = 70,000

The year David takes the loan = 2010

The year/loan balance relationship is y = -98·x² - 1,531·x + 69,710 (We note that the proper constant for the loan balance should be approximately 70,000, therefore the added zero)

Where;

x = The number of yeas

y = The balance

The year his loan balance will be $37,234.7, is given as follows;

37,234.7 = -98·x² - 1,531·x + 69,710

-98·x² - 1,531·x + 69,710 - 37,234.7 = 0

-98·x² - 1,531·x + 32,475.3 = 0

Factorizing with a graphic calculator, gives;

-98·(x - 11.998)·(x + 27.62) = 0

∴ x = 11.998 ≈ 12 or -27.62

The number of years it takes for the loan balance to be $37,234.7 = 12 years

Given that he took the loan in 2010, the loan balance will be $37,234.7 in 2010 + 12 = 2022

Determine whether the geometric series 36 + 39.6 + 43.56 + ... converges or diverges, and identify the sum if it exists.

svet-max [94.6K]

Answer:

Diverges

There is no sum.

Step-by-step explanation:

A geometric series has a general formula of:

$\sum ar^n$

Where 'a' is the initial term, 'n' is the number of terms, and 'r' is the constant ratio. If |r| < 1 than the series converges, but if |r| > 1, than the series diverges.

In this problem, the initial term is a = 36, the ratio can be found by:

$r = \frac{39.6}{36}=\frac{43.56}{39.6}\\ r=1.1$

Since the ratio is r =1.1 and 1.1 > 1.0, the series diverges.

In a diverging series, it is not possible to determine the sum of infinite terms, since it would be infinite.
