Answer:

f(-3) = 44

Step-by-step explanation:

f(x) = 2x² - 5x + 11

Substitute the value.

f(-3) = 2(-3)² - 5(-3) + 11

Raise -3 to the power of 2.

f(-3) = 2(9) - 5(-3) + 11

Multiply 2 and 9.

f(-3) = 18 - 5(-3) + 11

Multiply -5 and -3.

f(-3) = 18 + 15 + 11

Add 18 and 15.

f(-3) = 33 + 11

Add 33 and 11.

f(-3) = 44

Select the polynomial that is a perfect square trinomial. 36x2 − 4x 16 16x2 − 8x 36 25x2 9x 4 4x2 20x 25.

Naya [18.7K]

The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.

The given polynomial is

$a) 36x^2-4x+16$

What is the form of perfect square polynomial?

$(ax+b)^2$

we solve this method by using perfect square method

add and subtract 1/9

$36x^2-4x+16+\frac{1}{9}-\frac{1}{9}$

factor 36

$\frac{143}{9}+36(x^2-\frac{x}{9}+\frac{1}{324} )$

Now complete the square

$\frac{143}{9}+36(x^2-\frac{1}{18})^2$

Therefore this is not perfect square trinomial.

Similarly for

$b) 16x^2-8x+36$

Complete square is,

$16(x-\frac{1}{4})^2+35$

This polynomial is also not perfect square trinomial.

$c) 25x^2+9x+4\\$

complete square is,

$25(x+\frac{9}{50})^2+\frac{319}{100}$

This polynomial is not perfect square trinomial.

$d)4x^2+20x+25\\$

complete square is,

$(2x+5)^2$

This polynomial is perfect square trinomial.

Therefore,

The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.

A deposit of $10,000 is made into an account that earns 6% interest. Use

Georgia [21]

Answer:

$19,000

Step-by-step explanation:

The balance is the sum of the principal amount and the interest it earns:

A = P + I

A = P + Prt

A = P(1 +rt)

A = $10,000(1 +.06×15)

A = $19,000 . . . balance after 15 years
