A rocket is launched from the ground and travels in a straight path. The angle of inclination of the rocket's path is 1.2 radian

gladu [14]

Answer:

a) $S=2.57$

b) $H=203.2yard$

c) $X=121.79yards$

Step-by-step explanation:

From the question we are told that:

Angle $\theta=1.2=68.755^o$

Generally the equation for Slope is mathematically given by

$S=tan \theta$

$S=tan 68.755$

$S=2.57$

Given the right Angle triangle with horizontal distance $x=85yard$

Generally the equation for Height traveled is mathematically given by

$H=tan\theta*x$

$H=2.57*85$

$H=218.45$

$H=203.2yard$

Generally the equation for Horizontal Distance traveled at 313 height traveled is mathematically given by

$X=\frac{313}{tan65.75}$

$X=\frac{313}{2.57}$

$X=121.79yards$

Is the function in the table linear or nonlinear and why? x y 0,−100 and 1,-50 and 2,0 and 3,100 and 4,150. (A)The function is n

Studentka2010 [4]

Answer:

The correct option is c.

Step-by-step explanation:

Linear function: The rate of change of a linear function is always constant.

Non-Linear function: The rate of change of a non-linear function is not constant.

From the given coordinate pairs it is noticed that the function is passing through the points (0,-100), (1,-50), (2,0), (3,100) and (4,150).

$m=\frac{y_2-y_1}{x_2-x_1}$

The slope of function for points (0,-100) and (1,-50) is

$m_1=\frac{-50-(-100)}{1-0}=50$

The slope of function for points (2,0) and (3,100) is

$m_2=\frac{100-0}{3-2}=100$

Since the slopes of function are different, therefore the given function is non-linear.

The function is not linear because the rate of change is not constant and option c is correct.

You have decided to purchase a car for $25,625. The credit union requires a 10% down payment and will finance the balance

swat32

Answer:

Total purchase = $28498.685

In cent = 2849868.5 cent.

Step-by-step explanation:

Given : You have decided to purchase a car for 175.13.

To find : What is the total purchase price of the car including tax, license, and title?

Solution :

Price of car = $25,625

Sales tax = 7.5% = 0.075

The total purchase price of the car including tax is

T=25625\times 0.075=\$1921.875T=25625×0.075=$1921.875

Title charges are $175.13.

The credit union requires a 10% down payment and will finance the balance with a 9% annual interest loan for 36 months.

10% down payment on price of car

25625\times 0.10=2562.525625×0.10=2562.5

25625-2562.5=23062.525625−2562.5=23062.5

The amount will be $23062.5

Now, we find the monthly payment,

Monthly payment, M=\frac{\text{Amount}}{\text{Discount factor}}M=

Discount factor

Amount

Discount factor D=\frac{1-(1+i)^{-n}}{i}D=

1−(1+i)

−n

Rate = 9%=0.09

i=\frac{0.09}{12}=0.0075i=

0.09

=0.0075

Time n=36 month

Now, put all the values we get,

D=\frac{1-(1+i)^{-n}}{i}D=

1−(1+i)

−n

D=\frac{1-(1+0.0075)^{-36}}{0.0075}D=

0.0075

1−(1+0.0075)

−36

D=\frac{1-(1.0075)^{-36}}{0.0075}D=

0.0075

1−(1.0075)

−36

D=\frac{0.2358}{0.0075}D=

0.0075

0.2358

D=31.44D=31.44

Monthly payment, M=\frac{\text{Amount}}{\text{Discount factor}}M=

Discount factor

Amount

M=\frac{23062.5}{31.44}M=

31.44

23062.5

M=733.38M=733.38

Monthly payment is $733.38

For 36 months the payment is 733.38\times 36=26401.68733.38×36=26401.68

Licence = $26401.68

The total purchase price of the car including tax, license, and title

Total purchase = 1921.875 +1921.875+175.13 +$26401.68

Total purchase = $28498.685

1 dollar = 100 cent

$28498.685 = 2849868.5 cent.
