1. A rabbit can hop 6 feet in 2 seconds and 12 feet in 4 seconds. If the number of feet varies directly with the time the rabbit

kykrilka [37]

Answer: The rabbit is hopping at 3 feet/ sec in speed

Step-by-step explanation:

Step 1

Let the The number of feet of the rabbit be expressed as N

AND time rabbit spends hopping can be expressed as t

From the question, The number of feet varies directly with the time rabbit spends hopping can be expressed as

N α t

Let us introduce a constant of proportionality ,S which represents speed in this case, we now have that

N = St

STEP 2 -- SOLVING

If the rabbit hop 6 feet in 2 seconds, Then speed =

N = St

6= S X2

S = 6/ 2

S = 3

also

If the rabbit hop 12 feet in 4 seconds, Then speed =

N = St

12= S X 4

S = 12/ 4

S = 3

Also recall

that Speed = Distance / time

Pluging the values in the first case,

speed = 6 feet/ 2 secconds = 3 feet/ seconds

in the second case

Speed= 12 feet/ 4 second s= 3 feet/ secs.

The function y= 15.35 (1.0279)^t represents the value y(in dollars) of a share of stock after t days. Identify the initial amoun

Answer:

initial amount: $15.35
growth: 2.79% per day

Step-by-step explanation:

The coefficient is the initial amount: $15.35.

The growth factor is the base of the exponential term: 1.0279. The growth rate is 1 less than this: 1.0279 -1 = 0.0279 = 2.79%. It is positive, so represents a growth of 2.79% per day.

How do we get an<br> equation in slope-intercept form?

Viefleur [7K]

Answer:

y = mx + b

Step-by-step explanation:

1. m is the slope (lesson on slope ) mnemonic : 'm' means 'move'

2. b is the y -intercept ( lesson on the y-intercept ) mnemonic : 'b' means where the line begins.

Find the equation for a parabola with its focus at (0, 3) and a directrix of y = -3.

Elanso [62]

The equation of the parabola is $y=\frac{1}{24} x^2+3$

None of the given options is correct

Given:

Focus: (0, 3)

Directrix: y = -3

Note that:

f - k = k - (-3)

f - 3 = 3 + 3

f = 6 + 3

f = 9

The equation of the parabola is of the form:

$y=\frac{1}{4(f-k)} (x-h)^2+k$

Substitute f = 9, k = 3, h = 0 into the equation

$y=\frac{1}{24} (x-0)^2+3\\\\y=\frac{1}{24}x^2+3$

The equation of the parabola is $y=\frac{1}{24} x^2+3$
