Answer:
this may be wrond but I think it is -12 m/s
Step-by-step explanation:
The product of side length and altitude is area. The area remains the same regardless of how you measure it.
From the first side and altitude,
.. area = side*altitude = (4.2 cm)*(3.6 cm) = 15.12 cm^2
From the second side and altitude
.. area = side*altitude
.. 15.12 cm^2 = side*(2.4 cm)
.. side = (15.12 cm^2)/(2.4 cm) = 6.3 cm
The perimeter is the sum of the measures of all sides. Opposite sides are of equal measure.
.. perimeter = 2*(4.2 cm +6.3 cm) = 21.0 cm
Answer:
A
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 3, 5 ] , thus
f(b) = f(5) = - 26 ← value of y for x = 5 from table
f(a) = f(3) = - 10 ← value of y for x = 3 from table
average rate of change = = = - 8 → A
Answer:
47 strands
12 strands
Step-by-step explanation:
Given that:
Perimeter of a room = 48 feets
Number of rooms = 4
Strands of light to be used = 50 in
Converting the perimeter of a room to inches :
1 foot = 12 inches
48 feets = (12 * 48) = 576 inches
Total perimeter of the rooms in inches ;
576 inches * 4 = 2304 inches
Strands of 50 in light required for the 4 rooms;
2304 inches / 50 inches
= 46.08
= about 47 strands
Strands of light per room :
46.08 / 4
= 11.52 (about 12 strands)
= 12 strands
(Any number greater than zero) raised to the zero power = ' 1 '.
