Find the initial amount a and the decay factor b in the exponential function y=5.05^x

kvasek [131]

Answer:

$a = 5$

$b = .05$

Step-by-step explanation:

Given

$y = 5\ .05^x$

Required

Determine a and b

An exponential function is represented as:

$y =ab^x$

By comparing: $y =ab^x$ with $y = 5\ .05^x$

$a = 5$

$b = .05$

248 miles per hour = x meters per second. Round to the nearest hundredth.

Alja [10]

Answer:

Step-by-step explanation:

This problem is based on unit conversion from miles per hour to meter per second.'

From tables 1 mph= 0.44704 m/s

Given 248 mph to be converted to meters per second.

hence we have

1 mph= 0.44704 m/s

248 mph= x

cross multiplying we have

x= 110.86592 m/s

to the nearest hundreth we have

What would be the equation of the cannonball’s path if it was launched with the same velocity, but from the ground instead?

natita [175]

The quadratic equation cannonball’s path if it was launched with the same velocity, but from the ground instead would be given by:

$h(t) = -4.9t^2 + 19.8t$

<h3>What is the quadratic equation for the height of a projectile?</h3>

Considering the gravity, it is modeled by:

$h(t) = -4.9t^2 + v_0t + h_0$

In which:

$v_0$ is the initial velocity.

$h_0$ is the initial height.

For this problem, we want:

The same initial velocity, hence $v_0 = 19.8$ .

Launched from the ground, hence $h_0 = 0$ .

Then, the equation is:

$h(t) = -4.9t^2 + 19.8t$

Tell which term you would add or subtract on both sides side of the equation so that the variable is only on one side. 3y + 1 =

Pachacha [2.7K]

You would add 6 to both sides, leaving the equation to say 3y+7=4y
