A wooden board 100 centimeters long is cut into two pieces. One piece is 16 centimeters longer than the other. What are the leng

Bezzdna [24]

x = the length of one piece

y = the length of the other piece

the total length is 100 cm this means

x + y = 100

one piece is 16 inches longer than the other

first we need to convert inches to cm:

1 in = 2.54 cm

16 in = 2.54*16 = 40.64

now we can write

x = y + 40.64

by solving the system of equations

x + y = 100

x = y + 40.64

we find

x = 70.32 cm

y = 29.68 cm

the lengths of the two pieces are 70.32 cm and 29.68 cm.

Question 3 (4 MARKS) Find the equation of the tangents to the curve of the function with rule y = x^2 at the points where x = a

Arte-miy333 [17]

Answer:

(0 , -a²)

Step-by-step explanation:

tangent at x = a and x = -a

y = x² (a , a²) and (-a , a²) must be on the curve and tangent to curve

gradient dy/dx = 2x

slope (m) at x = a is <u>2a</u> and slope (m') at x=-a is<u> -2a</u>

line1: (y - a²) / (x - a) = 2a

y - a² = 2a (x - a) y = 2ax - a² ... (1)

line2: (y - a²) / (x + a) = - 2a y = -2ax- a² ... (2)

(1) - (2): 4ax = 0 a≠0 x = 0

y = - a²

I wish I did it right, or ....
