cert 22.2 U To 3. Draw an area diagram to find (0.36) (0.53). Label and organize your work so that it can be followed by others.
Masteriza [31]

The result of the product of (0.36) and (0.53) is 0.1908

<h3>How to determine the product</h3>

The product expression is given as:

(0.36) * (0.53)

Rewrite the product as follows:

(0.36) * (0.53) = (0.3 + 0.06) * (0.5 + 0.03)

Expand the product

(0.36) * (0.53) = 0.3 * (0.5 + 0.03)+ 0.06 * (0.5 + 0.03)

Expand

(0.36) * (0.53) = 0.15 + 0.009+ 0.03+ 0.0018

Evaluate the sum

(0.36) * (0.53) = 0.1908

See attachment for the area diagram of the product

Write the equation of the line in point-slope form. ASAP PLS !!!!
Vlad1618 [11]

Answer:

y - 1 = \frac{2}{3}(x - 3)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (3, 1) ← 2 points on the line

m = \frac{1+1}{3-0} = \frac{2}{3}

and using (a, b) = (3, 1 ) , then

y - 1 = \frac{2}{3} (x - 3)

F(x)=2x and g(x)=square root of x what is the domain of f(g(x))?
Dmitriy789 [7]

Answer:

x\ge 0

Step-by-step explanation:

The given functions are:

f(x)=2x


and


g(x)=\sqrt{x}


Now,

f(g(x))=f(\sqrt{x} )


f(g(x))=2\sqrt{x}

The domain refers to values of x for which f(g(x))=2\sqrt{x} is defined.


The  expression under the radical sign must not be negative.

The domain is

x\ge 0
