Answer: (a) 11.8
(b) 13
Step-by-step explanation:
Since George wants to put a string of lights around , it means we will have to consider the perimeter of the shape.
Perimeter of a rectangle is given by :
P = 2( L+B)
P = 2 ( 2.5 + 3.4)
P = 2 ( 5.9)
P = 11.8 meters
(b) Since he wants to put an addition to his wooden deck that is 0.6 meters longer , then the perimeter will be the perimeter of the first shape + 2(0.6). We used 2(0.6) because the two lengths of the rectangle must be considered
Therefore, we have
P = 11.8 meters + 2(0.6)
= 11. 8 + 1.2
= 13 meters
Therefore George needs 13 meters length of light
Answer:
y = 1/2x+1
Step-by-step explanation:
Slope = Δy/Δx
The difference is y increases by 1 and difference in x increases by 2. So the slope is 1/2.
Slope-intercept form: y=mx+b
We take point (0,1) and input into this equation.
1= 1/2×0 +b
1 = b
Take the derititve
f'(x)=3x^2+6x-24
set to zero
0=3(x^2+2x-8)
0=3(x-2)(x+4)
at x=2 and -4
those are where the min and max are
ok so
sign chart
to the lft of -4, the sign is positive
betweeen -4 and 2, the sign is negative
tothe right of 2 the sign is positive
max=sign changef from (+) to (-)
min=sign change from (-) to (+)
so max at x=-4 and min at x=2
find x=2, the value is -28
answer is C
2. 4th degree so quartic (qua, like quad or quadrilatal)
Rob Polanski is a tractor salesman. last week his total sales amounted to 38,642.00 and he received 2,704.94 in commission.Question: what is his rate of commission.=> 38 642 dollars = total sales he amounted.=> 2 704.94 dollars = total commision he receivedLet's find the unit rate base on the given data above.=2 704.94 / 38 642 = 0.07=> 0.07 * 100% = 7%<span>Thus, Rob received a 7% commision rate depending on the amount of his sales.</span>
