Answer:

y= -1x+7

Step-by-step explanation:

I believe this is the correct answer. The graph starts at 7 which is the y-intercept. And starts declining my -1

Answer:

y= -9/8x + 7

Step-by-step explanation:

You can use the equation y=mx+b or point slope form y-y1=m(x-x1)

Suppose a soccer goalie punted the ball in such a way as to kick the ball as far as possible down the field. The height of the b
Alexxx [7]

Answer:

57.98 yards

Step-by-step explanation:

When the ball is on the ground, the height is y=0, therefore:

y=-0.017x^2+0.98x+0.33

0=-0.017x^2+0.98x+0.33

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

x=\frac{-0.98\pm\sqrt{0.98^2-4(-0.017)(0.33)}}{2(-0.017)}

x_1=57.98184919

x_2=-0.3347903693

Since distance cannot be negative, the ball landed 57.98 yards down the field from where the goalie kicked the ball.

A pendulum clock is a clock that uses a swinging weight (a pendulum) as its
Gnoma [55]

Answer: x(t) = 5cm*cos(t*pi/2s)

Step-by-step explanation:

This is a sinusoidal equation, so we can write this as:

x(t) = A*cos(c*t + p)  + B

where B is the axis around the movement, as the resting position is x = 0, we have B = 0

so x(t) = A*cos(c*t + p)

A is the amplitude of the oscilation, c is the frequency and p is a phase.

We know that when t = 0s, we have x(2s) = 5cm

if this is the maximum displacement, then knowing that the maximum of the cosine is cos(0) = 1

then we must have that p = 0

x(0s) = A*cos(0) = 5cm

then we have A = 5cm

Now, when t = 2s, we have:

x(2s) = 5cm*cos(2s*c) = -5cm

then 2s*c is the minimum of the cos(x) function, this is:

cos(pi) = -1

then 2s*c = pi

c = pi/2s.

then our function is:

x(t) = 5cm*cos(t*pi/2s)

For r=2+3sintheta find dy/dx and the slope of the tangent line to the curve
brilliants [131]
F(x)=2+3sin(theta)
f'(x)=3cos(theta)

To find the slope you need the value of theta. The general formula is:

y-f(xo)=f'(xo)-(x-xo)
