Answer:
Step-by-step explanation:
f(x)=x+4(x^2+2x-3)=4x^2+9x-12
f'(x)=8x+9
f'(x)=0,gives x=-9/8
f(-5)=-5+4(-5-1)(-5+3)=-5+4*-6*-2=43
f(-9/8)=-9/8+4(-9/8-1)(-9/8+3)
=-9/8+4*-17/8*15/8
=-9/8-255/16
=-273/16=-17 1/16
f(5)=4*5^2+9*5-12=100+45-12=133
absolute maximum=133
absolute minimum=-17 1/16
5 and 6. square of 5 is 25 and square of 6 is 36. must be between 5 and 6
Interest = (Principal X rate X time)/100
Interest =421*9*4/100
Interest = 151.56 dollars
Answer:
<em>The surface area of square prism = 384 units squared</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<em>Given the square prism side 'a' = 8 units</em>
<em>The surface area of square prism = 2 a² + 4 a h</em>
Given square prism length , width and height also equal identical sides
The surface area of square prism = 2 a² + 4 a h
= 2(8)² + 4 (8)(8)
= 2(64) + 4(64)
= 384 units squared
<u><em>Final answer</em></u>:-
<em>The surface area of square prism = 384 units squared</em>
