I NEED HELP!

Mathematics
1 answer:
Butoxors [25]4 years ago
3 0

Answer:

Perimeter = 54.6 cm

Area = 173 cm²

Step-by-step explanation:

sin 30 = x/20

x = 10

cos 30 = y /20

y = 17.3

perimeter = 10 + 17.3 + 10 + 17.3 = 54.6 cm

area = 10 * 17.3 = 173 cm²

A police cruiser is traveling at 20.0 m/s when the officer spies a speeder. The cruiser accelerates at 3.0 m/s^2 for 5.0 seconds
Tema [17]

For the first 5.0 seconds, the cruiser covers a distance of

\left(20.0\dfrac{\rm m}{\rm s}\right)(5.0\,\mathrm s)+\dfrac12\left(3.0\dfrac{\rm m}{\mathrm s^2}\right)(5.0\,\mathrm s)^2=137.5\,\mathrm m

At this point, the cruiser will have achieved a velocity of

\left(20.0\dfrac{\rm m}{\rm s}\right)+\left(3.0\dfrac{\rm m}{\mathrm s^2}\right)(5.0\,\mathrm s)=35\dfrac{\rm m}{\rm s}

The cruiser will take

\left(35\dfrac{\rm m}{\rm s}\right)-\left(5.0\dfrac{\rm m}{\mathrm s^2}\right)t=0\implies t=7.0\,\mathrm s

to come to a stop as it decelerates. It will have covered a total distance of

(137.5\,\mathrm m)+\left(35\dfrac{\rm m}{\rm s}\right)(7.0\,\mathrm s)+\dfrac12\left(-5.0\dfrac{\rm m}{\mathrm s^2}\right)(7.0\,\mathrm s)^2=\boxed{260\,\mathrm m}

The function f(x) is a polynomial, while the function g(x) is a logarithmic function and the functions have the same range

<h3>The type of functions</h3>

The functions are given as:

f(x) = x³ + x² - 2x + 3

g(x) = log(x) + 2

The function f(x) is a polynomial, while the function g(x) is a logarithmic function.

<h3>The key features</h3>

For the polynomial function, we have:

  • Domain: -∞ < x < ∞
  • Range: -∞ < x < ∞
  • y-intercept = 3

For the logarithmic function, we have:

  • Domain: x > 0
  • Range: -∞ < x < ∞
  • y-intercept = undefined

By comparison, the functions have the same range
