Answer:
7/3
Step-by-step explanation:
f(x) = 3x^2 + 2x + 1, [0, 2]
f(0)=1
f(2)=17
f'(c)=f(2)-f(0)/2-1
f'(c)=17-1/1=16
f'(c)= 6x+2
6x+2=16
6x=16-2
6x=14
x=14/6
x=7/3
1. Shifts up 9
2. Shifts down 2
3. Reflect over x-axis and shifts left 5
4. Shifts right 4 and down 1
5. Vertical compression of 1/3 and shifts up 2
6. Reflect over x-axis, vertical stretch of 2, and shifts left 4
7. f(x)=-(x-3)^2+7
Sales tax = 5%
Sales Tax = $2
⇒ 5% is equal to $2
------------------------------------------------------------
Find 1%:
------------------------------------------------------------
5% = $2
1% = $2 ÷ 5
1% = $0.40
------------------------------------------------------------
Find 100% (Cost of the meal):
------------------------------------------------------------
100% = $0.40 x 100
100% = $40
------------------------------------------------------------
Find tips:
------------------------------------------------------------
15% tips = 15% x $40
15% tips = 0.15 x 40
15% tips = $6
------------------------------------------------------------
Find total cost:
------------------------------------------------------------
Total cost = $40 + $2 + $6 = $48
------------------------------------------------------------
Answer: $48
------------------------------------------------------------
Answer:
Option D
Step-by-step explanation:
(8x^2-9y^2-4x) +(x^2-3y^2-7x)
8x^2+x^2-9y^2-3y^2-4x-7x
9x^2-12y^2-11x
