1. what is the area of the board shown on the scale drawing? explain how you found the area.2. how can Adam use the scale factor

bixtya [17]

Answer:

1. 1800 square cm.

2. See below

3. 45000 square cm.

Explanation:

Part 1

The dimensions of the drawing are 36cm by 50cm.

$\begin{gathered} \text{The area of the board}=36\times50 \\ =1800\operatorname{cm}^2 \end{gathered}$

Part 2

Given a scale factor, k

If the area of the scale drawing is A; then we can find the area of the actual board by multiplying the area of the scale drawing by the square of k.

Part 3

$\begin{gathered} \text{Area of the scale drawing}=1800\operatorname{cm}^2 \\ \text{Scale Factor,k=5} \end{gathered}$

Therefore, the area of the actual drawing will be:

$\begin{gathered} 1800\times5^2 \\ =45,000\operatorname{cm}^2 \end{gathered}$

Find the equation of the line, where P is a point on the graph of the line. m=2/3 , P(3,5)

Liula [17]

Answer:

The answer is

$y = \frac{2}{3} x + 3$

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To write an equation of a line given a point and slope we have

y - y1 = m( x - x1)

where (x1 , y1 ) is the point and m is the slope

Equation of the line using point P(3 , 5) and m = 2/3 is

$y - 5 = \frac{2}{3} (x - 3)$

$y - 5 = \frac{2}{3} x - 2$

$y = \frac{2}{3} x + 5 - 2$

We have the final answer as

$y = \frac{2}{3} x + 3$

Hope this helps you

The formula κ(x)= f′′(x) 1+f′(x)23/2 expresses the curvature of a twice-differentiable plane curve as a function of x. Use thi

Katyanochek1 [597]

Answer:

K(x) = $\frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }$ ( curvature function)

Step-by-step explanation:

considering the Given function

F(x) = $-5x^2$

first Determine the value of F'(x)

F'(x) = $\frac{d(-5x^2)}{dy}$

F'(x) = -10x

next we Determine the value of F"(x)

F"(x) = $\frac{d(-10x)}{dy}$

F" (x) = -10

To find the curvature function we have to insert the values above into the given formula

K(x) $= \frac{|f"(x)|}{[1 +( f'(x)^2)]^{\frac{3}{2} } }$

K(x) = $\frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }$ ( curvature function)

One half of the difference of a number and three will result in two thirds of the difference of the number and eight

cupoosta [38]

1/2(x - 3) = 2/3(x - 8)

Distributive property on both sides.

0.5x - 1.5 = 0.7x -5.3

Add 5.3 to both sides.

0.5x + 3.8 = 0.7x

Subtract 0.5x from both sides.

3.8 = 0.2x

Multiply both sides by 5.

x = 19 (This is your answer.)

Let me know if you have any other questions. :)
