What is the length of segment SR?

A. y = 1x +4

B. y = -2x +4

C. y = -6

D. x = 1

We convert 2 into 6/3.

Now, we add the fraction part of the mixed number with 6/3
-> 5/3 + 6/3 = 11/3

So, it is equal to 4(11/3)

Now, we convert 11/3 into 3(2/3)
-> 4(11/3) = 4+3(2/3) = 7(2/3).

Step-by-step explanation:

The average velocity of the entire trip is 42.5 mph east

An object's average velocity is calculated by dividing its total displacement by its total travel time.

It measures how quickly an object shifts from one location to another.

It is a Vector magnitude

For one hour, an automobile travels 25.0 miles due east.

Then it continues for an extra hour and travels another 60.0 miles east.

We must determine his overall journey average speed.

He does the entire journey going straight east.

He travels a total distance of 25 + 60 = 85 miles east.

He takes an hour to get there from here and another hour to get there from there.

The total travel time is 1 + 1 = 2 hours.

Total displacement times total time equals the average velocity.

His average speed = 85 ÷ 2 = 42.5 miles/hour east

The average velocity of the entire trip is 42.5 mph east

If I throw a ball with an Initial velocity Vi=10 m/s with an angle Theta of 60 degrees above the Horizontal axis x, then the velocity Vx and Vy are; C. Vx= 5 m/s Vy=8.66 m/s

The formula to find the velocity of an object thrown at an angle is;

Horizontal velocity component; Vx = v_i*cosθ

Vertical velocity component; Vy = v_i*sinθ

where;

v_i is initial velocity

θ is angle at which object is thrown.

Now, we are given that;

Initial velocity; v_i = 10 m/s

Angle of throw; θ = 60°

Thus;

V_x = 10 * cos 60

V_x = 10 * 0.5

V_x = 5 m/s

V_y = 10 * sin 60

V_y = 10 * 0.8660

V_y = 8.66 m/s

Applying the triangle sum theorem, the value of w in the triangle is calculated as: w = 29.

The triangle sum theorem states that if we add up all the three interior angles of any given triangle, we will have a sum of 180 degrees.

This means that, irrespective of whatever triangle that is given, the sum of all the interior angles of such triangle will be equal to 180 degrees.

The diagram attached below shows the following interior angle measures of a triangle: 35°, 2w, and 3w.

To find the value of w in the triangle given, we have to create an equation using the triangle sum theorem that will enable us solve for the value of w.

Thus:

35 + 2w + 3w = 180° [according to the triangle sum theorem]

Combine like terms

35 + 5w = 180

Subtract both sides by 35

35 + 5w - 35 = 180 - 35 [subtraction property of equality]

5w = 145

Divide both sides by 5

5w/5 = 145/5 [division property of equality]

w = 29

Step-by-step explanation:

If radium-221 has half life of 30 seconds. To decay 86% of the the sample, it will take 85.09 seconds

The half life of the radium-221 = 30 seconds

To decay 86% of the sample

The equation of the half life N = [tex]N_0(\frac{1}{2} )^\frac{t}{t_1}[/tex]

Where N is the quantity of substance remaining

[tex]N_0[/tex] is the initial quantity of substance

t is the time elapsed

[tex]t_1[/tex] is the half life of the substance

Substitute the values in the equation

0.14[tex]N_0[/tex] = [tex]N_0(\frac{1}{2} )^\frac{t}{30}[/tex]

Cancel the [tex]N_0[/tex] from each side

0.14 = [tex](\frac{t}{30} )^\frac{t}{30}[/tex]

[tex]2^\frac{t}{30}=\frac{1}{0.14}\\ \frac{t}{30}=log_2\frac{1}{0.14}\\ t = 30log_2\frac{1}{0.14}[/tex]

t = 85.09 seconds

The height of the baseball thrown is 5 feet.

The function or equation for the height of the ball at a certain time t is given as:

h( t ) = - 16t² + 100t + 5

When the ball will reach the ground the height of the ball will be h = 0.

Therefore,

- 16t² + 100t + 5 = 0

Comparing the equation with general quadratic equation ax² + bx + c =0

Using the quadratic formula,

[tex]t=\frac{-b\pm \sqrt{b^{2} - 4ac } }{2a}[/tex]

[tex]t = \frac{-100\pm \sqrt{(100)^{2} - 4(-16)(5) } }{2(-16)}[/tex]

The rate of change of the area at the instant the radius is 10 ft is 376.99 ft² / min.

The rate of change describes how one quantity changes in relation to the change in another quantity.

If a circle has an initial radius of 50 ft and decreases at a rate of 2 ft/min, then the time it took the radius to become 10 ft is 20 min.

r = r₀ - (rate)(time)

10 ft = 50 ft - (2 ft/min)(time)

(2 ft/min)(time) = 40 ft

time = 20 min

Solve the rate of change in area by dividing the change in area after time = 20 min.

rate of change = change in area / change in time

rate of change = A(r = 50) - A(r = 10) / 20 min

rate of change = π(50² - 10²) / 20 mins
