Answer:

y = x² + 3x - 40

Step-by-step explanation:

Given the zeros are x = - 8 and x = 5, then the factors are

(x + 8) and (x - 5) and

y = (x + 8)(x - 5) ← expand factors

y = x² - 5x + 8x - 40, hence

y = x² + 3x - 40 ← in standard form

0.580000 as a fraction

Paul [167]

Answer:

$\frac{58}{100}=\frac{29}{50}$

Step-by-step explanation:

Since this is mathematics, significant figures are not necessary. Thus, we can just take 0.58 and delete the 0s. Now, $0.58=\frac{58}{100}$ .

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule.

lubasha [3.4K]

Answer:

The answer is option C.

Step-by-step explanation:

The arithmetic sequence is given by

$A(n) = - 6 + (n - 1)( \frac{1}{5} )$

where n is the number of terms

For the first term

n = 1

So we have

$A(1) = - 6 + (1 - 1)( \frac{1}{5} )$

$= - 6 + (0)( \frac{1}{5} )$

$= - 6$

For the fourth term

n = 4

$A(4) = - 6 + (4 - 1)( \frac{1}{5} )$

$= - 6 + (3)( \frac{1}{5} )$

$= - 5 \frac{2}{5}$

For the tenth term

n = 10

$A(10) = - 6 + (10 - 1)( \frac{1}{5} )$

$= - 6 + (9)( \frac{1}{5} )$

$= - 4 \frac{1}{5}$

Hope this helps you

The function f(3) = 50.000(0.975)", where x represents the underwater

valentina_108 [34]

9514 1404 393

Answer:

316 lumens/m²

Step-by-step explanation:

We assume your intensity function is ...

f(x) = 50,000(0.975^x) . . . . x meters below the surface

Use 200 for x and do the arithmetic.

f(200) = 50,000(0.975^200) ≈ 316 . . . . lumens/m²
