Only find the vertex and axis of symmetry
lara [203]

Answer:

vertex (5,2)

axis of symmetry: x=5

Step-by-step explanation:

vertex (h,k)

y = a(x - h)² + k

f(x)=(x-5)²+2        a = 1     h = 5      k = 2

vertex (5 , 2)

The axis of symmetry always passes through the vertex of the parabola. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

x = 5

Answer:

352x^2

Step-by-step explanation:

40\times 1.25x\times 2.20x\times 3.2040×1.25x×2.20x×3.20

(40)1.25x2.20x3.20

+ − .   ln > <

× ÷ /   log ≥ ≤

( )    logx = %

1 Take out the constants.

(40\times 1.25\times 2.20\times 3.20)xx(40×1.25×2.20×3.20)xx

2 Simplify  40\times 1.2540×1.25  to  5050.

(50\times 2.20\times 3.20)xx(50×2.20×3.20)xx

3 Simplify  50\times 2.2050×2.20  to  110110.

(110\times 3.20)xx(110×3.20)xx

4 Simplify  110\times 3.20110×3.20  to  352352.

352xx352xx

5 Use Product Rule: {x}^{a}{x}^{b}={x}^{a+b}x

Each length unit on the speedway diagram represents one-tenth of a mile. What is the area of the sector associated with turn A i
Alecsey [184]
We know that 
area of a circle=pi*r²
turn A
r=3 units------> 3*(1/10)----> 0.3 miles
area of a circle=3.142*0.3²-----> 0.28278 miles²

by proportion
0.28278/360°=A/90°------> A=90*0.28278/360------> A=0.0707 miles²

the answer is
0.0707 miles²
