A baseball player hits a pitched ball when it is 4 ft above the ground. The initial upward velocity is 80 ft/s. How

iren [92.7K]

Answer:

t=+4.06

Step-by-step explanation:

when the baseball hits the ground, the height will be 0.

h=0we are given that h=−16t2+64t+4.

this means that the height is 0 when −16t2+64t+4=0.−16t2+64t+4=0divide both sides by 4:−4t2+16t+1=04=0−4t2+16t+1=0 can be solved using the quadratic formula:t=−b±√b2−4ac2a, where at2+bt+c=0.at2+bt+c=−4t2+16t+1a=−4,b=16,c=1t=−b+√b2−4ac2aor−b−√b2−4ac2a−b+√b2−4ac2a=−16+√272−8=−0.06..−b−√b2−4ac2a=−16−√272−8=4.06 (3s.f.)we have 2 values for t:−0.06 and 4.06.

since time cannot be negative, only the positive value can be taken.

this is 4.06, to 3 significant figures.the time taken is 4.06 seconds.

A billiard ball is struck by a cue. It travels 100 cm before ricocheting off a rail and traveling another 100 cm into a corner p

Airida [17]

Answer:

76.53 cm

Step-by-step explanation:

From the question, the triangle formed has 2 sides and an included angle ;

Angle, θ = C = 45°

We use cosine rule :

Taking the side to find as c

a = 100 ; b = 100

From cosine rule :

c = sqrt(a² + b² - 2abCosC)

c = sqrt(100² + 100² - 2(100*100)Cos45

c = sqrt(10000 + 10000 - 20000 * 0.7071067)

c = sqrt(20000 - 14142.135)

c = sqrt(5857.865)

c = 76.536690

c = 76.53 cm

Indicate the equation of the given line in standard form. The line with slope 9/7 and containing the midpoint of the segment who

professor190 [17]

Given parameters:

Coordinates of end points = (2, -3) and (-6,5).

Slope of line = $\frac{9}{7}$

Unknown:

Equation of the line with the given slope = ?

Solution:

Let us find the coordinates of the mid-point of the line given.

Since the end points are (2, -3) and (-6,5);

Midpoint;

x, y = $\frac{x_{1} + x_{2} }{2}$ , $\frac{y_{1} + y_{2} }{2}$

x, y = $\frac{2 + (-6)}{2}$ , $\frac{-3 + 5}{2}$ = -2 , 1

The coordinate of the mid point = -2,1

Equation of a line is;

y = mx + c

x and y are the coordinates

m is the slope

c is the y intercept

We need to find c in order to fully develop our equation;

y = mx + c

y = 1 , x = -2 and m = $\frac{9}{7}$

So,

1 = $\frac{9}{7}$ x (-2) + c

c = 1 + $\frac{18}{7}$ = $\frac{25}{7}$

Now, the equation of the line is;

y = -2x + $\frac{25}{7}$

Multiply through by 7,

7y = -14x + 25

The equation of the line is 7y = -14x + 25
