A baseball is thrown up in the air. The table shows the heights y (in feet) of the baseball after x seconds.
lawyer [12517]

Answer:

Alright, we can express the baseball's motion with an equation like:

h(x) = a*x^2 + b*x + c

Here, x denotes time, while h(x) indicates height.

Let’s construct this:

The acceleration is:

a(t) = a

For velocity, integrating over time results in:

v(x) = a*x + v0

Where v0 signifies the initial vertical velocity.

Subsequently, we can determine position or height by integrating once more:

h(x) = a*x^2 + v0*x + h0

Here, h0 is the initial height.

<pthus our="" equation="" is:="">

h(x) = a*x^2 + v0*x + h0.

<pexamining the="" table:="">

When x = 0s, h(0s) = 6ft

<pthus:>

h(0s) = a*0s^2 + v0*0s + h0 = 6ft

            h0 = 6ft.

It’s also noted that:

h(2s) = h(4s)

<pthe symmetry="" of="" the="" quadratic="" function="" implies="" that="" axis="" lies="" between="" and="" located="" at="" x="3s.&lt;/p"><pin a="" standard="" quadratic="" function:="">

a*x^2 + b*x + c

The symmetry line is given by:

x = -b/2a

<pin this="" instance:="">

b = v0

a = a

<ptherefore we="" derive:="">

3s  = -v0/(2*a)

v0 = -3s*(2a)

<phaving gathered="" all="" necessary="" data="" for="" our="" equation="" we="" can="" express="" it="" as:="">

h(x) = a*x^2 - 6s*a*x + 6ft

<pnext focusing="" on="" just="" one="" variable="" we="" know="" that="" at="" x="2s," h=""><pso:>

h(2s) = 22ft = a*(2s)^2 - 6s*a*2s + 6ft

<pthus our="" resulting="" equation="" reads:="">

h(x) = (-2ft/s^2)*x^2 + (12ft/s)*x + 6ft

b) The height after 5 seconds is expressed as:

h(5s) =  (-2ft/s^2)*(5s)^2 + (12ft/s)*5s + 6ft = 16ft

Three ships, A, B, and C, are anchored in the atlantic ocean. The distance from A to B is 36.318 miles, from B to C is 37.674 mi
Leona [12618]

Let's sketch the triangle.

The sides are a= 37.674 miles

b= 11.164 miles

c= 36.318 miles

We'll apply the cosine rule for angle calculations

(since the sine law cannot be employed without knowing any angle measurements).

The cosine law is given by

c^{2} = a^{2} +b^{2} -2ab cos C

Substituting the values results in

(36.318)^{2} = (37.674)^{2} + (11.164)^{2} - 2(37.674)(11.164). Cos C

1318.997 = 1419.33 + 124.634 - 841.184. Cos C

1318.997 = 1543.964 - 841.184. Cos C

841.184. Cos C = 1543.964-1318.997

841.184. Cos C = 224.967

Cos C = \frac{224.967}{841.184}

cos C = 0.267

C = 74.48°

We can find angle A using the sine law

\frac{a}{SinA} = \frac{c}{Sin C}

\frac{37.674}{Sin A} = \frac{36.318}{Sin 74.48}

Sin A = \frac{37.674. sin 74.48}{36.318}

Sin A = \frac{37.674 X 0.963}{36.318}

Sin A = 0.998

A= sin^{-1} (0.998)

A = 87.38°

The third angle B can be determined by calculating 180° minus the sum of angles A and C

B = 180-(74.48 + 87.38)

B = 180 - 161.86

B = 18.14°

Thus, we have calculated all three angles (as shown in the attached figure).
