You must use the formula for the circumference of a circle which is 19*3.14. That is the distance the wheel travels in one revolution.

B(1)= 160, b(n) = b(n-1) * 0.5 for n (g/e) 2 determine the first 4 items in a sequence given this recursive formula.

Paul [167]

Answer:

160

80

40

20

Step-by-step explanation:

You start with the first term that is given which would be

b(1)=<u><em>160</em></u>

That would be our first term, then we multiply by 0.5 which would be 1/2

which gives us 80 as it is a division

You take the next term that we have found (80) and then we do the same thing, multiply by 0.5 (1/2)

Write an equation for the proportional relationship. Can you compare these two tables?

Viktor [21]

Answer:

Y=1.88x

Step-by-step explanation:

x1=2 x2=3, y1=3.76 y2=5.64

(2, 3.76) (3, 5.64)

m(slope) =5.64-3.76/3-2

m=1.88

y-3.76=1.88(x-2)

y-3.76=1.88x-3.76

Y=1.88x

The vertex of this parabola is at (2, -4). When the y-value is -3, the x-value is -3. What is the coefficient of the squared ter

lyudmila [28]

Answer:

The squared term is 1/25

Step-by-step explanation:

The parabola equation in the vertex form is

$y = a \times (x - h)^2 + k$

where point (h,k) is the vertex and a is the squared term. In this case h = 2 and k = -4. On the other hand, we know that y = -3 and x = -3 are in the parabola. Replacing these values in the formula gives

$-3 = a \times (-3 - 2)^2 - 4$

Solving for a

$-3 + 4 = a \times (-5)^2$

$1 = a \times 25$

$a = \frac{1}{25}$
