Given the function f(x) graphed on the coordinate plane 15

Draw an area model that demonstrates that the quotient of 2080 and 40 is 52.

Scrat [10]

Area model is used to illustrate multiplication and division operations.

See attachment for the area model

The equation can be represented as:

$\frac{2080}{40} = 52$

Express 2080 as 1200 + 800 + 80

$\frac{1200 + 800 + 80}{40}=52$

Express as

$\frac{1200 + 800 + 80}{40}=\frac{1200}{40} + \frac{800}{40} + \frac{80}{40}$

Divide

$\frac{1200 + 800 + 80}{40}= 30 + 20 + 2$

2018 copper penny struck at the Philadelphia mint in 1794 was sold for 345000 rate of return

vodomira [7]

Answer:

The rate of return is 8%.

Step-by-step explanation:

The time span from 1794 to 2018 is (2018 - 1794) = 224 years.

Now, a penny i.e. 0.01 pounds of money as a principal gets the final sum of 345000 pounds after 224 years.

Here we have to calculate the rate of return if the interest is compounded yearly.

Using the formula of compound interest of r% APR, we get

$345000 = 0.01 (1 + \frac{r}{100})^{224}$

⇒ 1 + 0.01r = 1.08

⇒ 0.01r = 0.08

⇒ r = 8% (Answer)

Find a polynomial with the following zeros. HELPPPP ASAPPP

Pavlova-9 [17]

Answer:

x³ - 4x² + 2x + 4 = 0

Here's how I solved this:

You start off by rewriting the zeros into factors:

1 - √3 → x = 1 - √3 → (x - 1 - √3)

2 → x = 2 → (x - 2)

1 + √3 → x = 1 + √3 → (x - 1 + √3)

Now you want to multiply the factors together:

(x - 1 - √3) · (x - 2) · (x - 1 + √3)

- Multiply the first two factors together -

(x - 1 - √3) · (x - 2)

↓

(x · x - x · 2 - √3 · x + √3 · 2 - x + 2)

- Combine like terms and simplify -

(x · x - x · 2 - √3 · x + √3 · 2 - x + 2)

↓

(x² - 3x - √3 · x + 2√3 + 2)

- Now multiply the third factor -

(x² - 3x - √3 · x + 2√3 + 2)(x - 1 + √3)

↓

(x² · x + x² · √3 - x² - 3x · x - 3x · √3 + 3x - √3 · xx - √3 · x · √3 +√3 · x + 2 · √3 · x + 2 · √3 · √3 - 2 · √3 + 2x + 2 · √3 - 2)

↓

(x³ + x² · √3 - x² - 3x² - 3x · √3 + 3x - √3 + 3x - √3 * x² - x · 3 + √3 · x + 2 · √3 · x + 2 · 3 - 2 × √3 + 2x + 2 √3 - 2)

- Combine like terms and simplify -

(x³ + x² · √3 - x² - 3x² - 3x · √3 + 3x - √3 + 3x - √3 * x² - x · 3 + √3 · x + 2 · √3 · x + 2 · 3 - 2 × √3 + 2x + 2 √3 - 2)

↓

x³ - 4x² + 2x + 4

--------------------------------------------------------------------------------------------------------------

And there we get our solution: x³ - 4x² + 2x + 4

What is the area of the right triangle shown below?

Hatshy [7]

Answer:

1.5

Step-by-step explanation:

base x height x 0.5

Pythagorean theorem: c^2 - a^2 = b^2

b = square root of (2.5)^2 - (1.5)^2

= 2

b = height

area = 0.5 x 1.5 x 2 = 1.5
