Find the slope of DE and FG

Mathematics
1 answer:
Pavlova-9 [17]3 years ago
7 0

Answer:

Part 1) The slope of DE is m=\frac{c}{a+b}

Part 2) The slope of FG is m=\frac{c}{a+b}

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

step 1

Find the slope of DE

we have

D(-a-b,c) and E(0,2c)

substitute in the formula

m=\frac{2c-c}{0-(-a-b)}

m=\frac{c}{a+b}

step 2

Find the slope of FG

we have

F(a+b,c) and G(0,0)

substitute in the formula

m=\frac{0-c}{0-(a+b)}

m=\frac{-c}{-(a+b)}

Simplify the sign minus

m=\frac{c}{a+b}

Note The slope of DE is equal to the slope of FG. therefore DE and FG are parallel

schepotkina [342]

Answer:

depreciation to be allocated to A = 2800tons x $0.600 /ton

        = $1680

Step-by-step explanation:

  • First calculate the amount of depreciation/ton
  • depreciation per ton = $125,000/208,000 = $0.600 /ton
  • Hence depreciation to be allocated to A = 2800tons x $0.600 /ton

        = $1680

Use the product property of roots to choose the expression equivalent to 3√5x*3√25x^2?
nignag [31]

Answer: \sqrt[3]{125x^3}.


Step-by-step explanation: Given radical expression

\sqrt[3]{5x} \times \sqrt[3]{25x^2}.

According to the product property of roots.

\sqrt[n]{a} \times \sqrt[n]{b} = \sqrt[n]{a \times b}

On applying above rule, we get

\sqrt[3]{5x} \times \sqrt[3]{25x^2} = \sqrt[3]{5x \times 25x^2}

5 × 25 = 125 and

x \times x^2 = x^3

Therefore,

\sqrt[3]{5x \times 25x^2}= \sqrt[3]{125x^3}

<h3>So, the correct option would be second option \sqrt[3]{125x^3}.</h3>

Professor Vinculum investigated the migration season of the Bulbul bird from their natural wetlands to a warmer climate. He foun
coldgirl [10]

The population of the Bulbul birds at the start of the migration season is 1800.

<h3>Exponential function</h3>

An exponential function is given by:

y = abˣ

Let y, x are variables, a is the initial value and b is the multiplication factor.

Let P be the population of the bird t days since the start of the migration season.

P=1350+400(1.25)^{-t}\\\\At\ the\ start\ of\ the\ season(t=0):\\\\P=1350+400(1.25)^{-0}\\\\P=1350+450=1800

The population of the Bulbul birds at the start of the migration season is 1800.
