Use the given point on the terminal side of angle 0 to find the value of the trigonometric function indicated.

1 answer:

8 0

1 is tan 0 = -18/10 = -9/5
2 is tan 0 = 3/4

In general, an angle with a terminal side on the point (x, y) the tan of that line is the fraction y/x

What is 1/6x=4 in solving equations with rational coefficients

Debora [2.8K]

To solve an equation with a rational (fraction) coefficient you need to multiply both sides of the equation by the reciprocal (invert the fraction - flip it).

$\frac{1}{6}x =4$ The reciprocal of 1/6 is 6/1 or 6
$6( \frac{1}{6} x)= 6(4)$ The product of reciprocals equals 1
1x = 24
x = 24

A new car costs $8000 at full price. With a sales tax of 5.75%, how much will the car cost in total?

ioda

Answer:

$8460

Step-by-step explanation:

So for this problem we will use the base price of $8000 and add the additional cost of the 5.75% to find the total cost for the car.

So, to find the 5.75%, we simply multiply 8000 by .0575 to get 460.

So 8000 + 460 = 8460.

Thus, the total price of the car would be $8460.

Cheers.

A water balloon is tossed into the air with an upward velocity of 25 ft/s. Its height h(t) in ft after t seconds is given by the

iren2701 [21]

1) $h (t) = -16t^2 + 25t + 3 \\ \\h(t) = 0 \\ \\ 0 = -16t^2 + 25t + 3 \\ \\ quadratic \ formula \\ \\ a = -16 \ , \ b = 25 \ , c = 3 \\ \\ t = \frac{-25 \pm \sqrt{25^2-4(-16)(3)} }{2(-16)} \\ \\ \frac{-25 \pm \sqrt{625+192} }{-32} \\ \\ \frac{-25 \pm \sqrt{817} }{-32} \\ \\ \frac{-25 \pm 28.5832}{-32} \\ \\ t = \frac{-25 - 28.5832}{-32} \\ \\ t = \frac{-25 + 28.5832}{-32} \\ \\ \frac{53.5832}{32} \\ \\ \frac{53.5832}{32} \\ \\ 1.66447$

The water ballon will hit the ground after 1.66447 seconds.

--------

2) $t = 1 \\ \\ h(1) = -16(1)^2 + 25(1) + 3 \\ \\ -16 + 25 + 3 \\ \\ 12$

The height will be 12 feet if t = 1 second.
