Answer:
- 8
Step-by-step explanation:
Evaluate f(1) and f(- 1) by substituting x = 1 and x = - 1 into f(x)
Given
f(x) = x² - 4x + 6, then
f(1) = 1² - 4(1) + 6 = 1 - 4 + 6 = 3
f(- 1) = (- 1)² - 4(- 1) + 6 = 1 + 4 + 6 = 11
Thus
f(1) - f(- 1) = 3 - 11 = - 8
Part A)
Section A : 4
Section B : 36
Part B) 9 times
because exponential function grows faster with larger x
First, convert 3 into a fraction with denominator 8.
(3 pizzas)(8/8 pizzas)=24/8 pizzas
Then, divide 24/8 pizzas by 2/8 pizzas per 1 person.
(24/8 pizzas)(2/8 pizzas/person)
Dividing by a fraction is the same as multiplying by the reciprocal:
(24/8)/(2/8)=(24/8)×(8/2) the 8s cancel and you are left with 24/2=12
3 pizzas will feed 12 people.
It's 3.01 sorry wrong question please forgive me
tanX is 12/5.
Given:
In a right triangle,
The length of the side <em>XY</em> = 13.
The length of the side <em>YZ</em> = 12.
The length of the side <em>XZ</em>= 5.
The objective is to find tan <em>X</em>.
In a right angled triangle the largest side is always hypotenuse.
Sinec tan <em>X</em> is required to solve, then, the side <em>YZ </em>is opposite side and the side <em>XZ</em> is adjacent side.
By the trigonometric ratios, the value of tan <em>X</em> can be calculated as,

Hence, the value of tanX is 12/5.
