Answer:

a. Jake told the negative value of the expression which cannot be equivalent to the original expression.

b. 10 - $\frac{\textbf{3}}{\textbf{7}}$ g

Step-by-step explanation:

a. The given expression is: $\frac{-3}{7}g + 10$

Multiplying through out by -, we get:

$- 10 + \frac{3}{7}g$ which was the expression given by Jake. Since, it is the negative of the original one, they cannot be equivalent.

b. $-\frac{3}{7}g + 10 = 10 - \frac{3}{7}g$

$= \frac{70 - 3g}{7}$

Hence, the answer.

Determine if the statement is always, sometimes or never true.

Romashka-Z-Leto [24]

Let

x--------> the measure of the adjacent interior angle

y--------> the measure of an exterior angle at the vertex of a polygon

we know that

The measure of the adjacent interior angle and the measure of an exterior angle at the vertex of a polygon are supplementary angles

$x+y=180$ °

Examples

case 1)

In a square

$x=90$ °

$y=180-90=90$ °

$x=y$

In this case

The measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle

case 2)

an equilateral triangle

$x=60$ °

$y=180-60=120$ °

$x\neq y$

In this case

The measure of an exterior angle at the vertex of a polygon is not equals the measure of the adjacent interior angle

therefore

the answer is

sometimes

Answer:

a) V_avg = 32 ft/s

b) V_avg = -30 ft/s

c) See explanation

Step-by-step explanation:

Given:

- The displacement function is given:

S(t) = -16t^2 + 64t + 80

Find:

a. Find the balls average velocity between the time it was thrown and 2 seconds later

b. Find the ball’s average velocity between 2 and 4 seconds after it was thrown

c. What do the signs in your answers to parts (a) and (b) mean in terms of the direction of the ball’s motion?

Solution:

- The average velocity of an object is the displacement over time, and it is expressed as follows:

V_avg = ( S_2 - S_1 ) / dt

- Evaluate S(2), S(0), and S(4):

S(2) = -16*2^2 +64*2 +80

S(2) = 144 ft

S(0) = -16*0^2 +64*0 +80

S(0) = 80 ft

S(4) = -16*4^2 +64*4 +80

S(4) = 80 ft

- For part a. Compute V_avg:

V_avg = ( S(2) - S(0) ) / 2

V_avg = (144 - 80) / 2

V_avg = 32 ft/s

- For part b. Compute V_avg:

V_avg = ( S(4) - S(2) ) / 2

V_avg = (80 - 140) / 2

V_avg = -30 ft/s

- We see that the signs of the Velocity have changed. The coordinate axis up against gravity was chosen to positive. While a negative access is in favor of the gravity. Hence, from the signs we can see that the ball is going down towards ground in motion from t = 2 s to t = 4 s.
