A technology start-up company has had 5 different CEOs since it was founded. The tenures of these CEOs – the number of months that they held the position – are given in the table below. These 5 CEOs are the population you are interested in.
Answer:
9 sq. units
Step-by-step explanation:
dimensions of rectangle are (7-3),(8-3)
or 4,5
area of rectangle=4×5=20
area of bottom Δ=1/2×4×2=4
area of top Δ=1/2×3×3=9/2
area of right triangle=1/2 ×5×1=5/2
area of Δ HIJ=20-(4+9/2+5/2)
=20-(4+14/2)
=20-(4+7)
=9 sq. units.
or area of triangle =1/2
| 3 5 |
| 7 3 |
|6 8 |
|3 5 |
=1/2[(9-35)+(56-18)+(30-24)]
=1/2[-26+38+6]
=1/2[-26+44]
=1/2(18)
=9 sq. units.
F(x)=7x+9
f´(x)=7
f´(6)=7
answer: f´(6)=7
f´(x)=Lim x⇒0 (f(x+h)-f(x)) / h
f´(6)=lim x⇒ 0 (7(6+h)+9 -(7*6+9)) / h
=lim x⇒0 ( 42+7h+9-42-9) /h
=lim x⇒0 (7h/h)=7
answer: f´(6)=7
Answer:
a) He calculated the area, not the circumference. The equation for the area of a circle is πr², while the equation for the circumference is 2πr.
b) He would need at least 3 quarts of paint. 200.96/75≈2.68 He would need that approximately 2.68 quarts of paint, but I suppose the question is asking you the least amount of whole number quarts of paint. The answer for that would then be 3.
