Answer:
20 in^2
Step-by-step explanation:
The end is a trapezoid
The area of a trapezoid is
A = 1/2 (b1+b2) *h
where b1 =4 and b2 =6 and h =4
A = 1/2 (4+6) *4
A = 1/2 (10)*4
=20 in^2
It would be 19. Because...
Expression: $0.55n = $10.45
Work: 10.45 / 0.55 = 19 ounces
Proof: 19 x 0.55 = $10.45
Answer:
58 degrees
Step-by-step explanation:
i)
<u>Factor using completing square method</u>
ii)
<u>Find zeros of a function, f(x) = 0</u>
iii)
<u>In order to find vertex use the formulae : x = -b/2a</u>
Then find y:
coordinates: (8, 0)
iv) Sketched Below:
