Answer:
Step-by-step explanation:
Projectile motion is a form of motion in which an object or particle (called a projectile) is thrown
near the earth's surface, and it moves along a curved path under the action of gravity only.
In projectile motion, the horizontal motion and the vertical motion are independent of each
other; that is, neither motion affects the other.
The horizontal component of the velocity of the object remains unchanged throughout the
motion. The vertical component of the velocity increases linearly, because the acceleration due to
gravity is constant (g=9.81 m/s2
).
= 0 cos
0 = 0 sin
To find the time of flight, determine the time the projectile takes to reach maximum height.
The time of flight is just double the maximum-height time.
Start with the equation:
= 0 + = 0 −
At maximum height,
= 0
The time to reach maximum height is

<span>Given that Tamara's annual salary is $48,000 means that his monthly salary is $48,000 / 12 = $4,000. For Tamara to make $6,000 this month, she needs to make an additional $2,000 from commissions in addition to her salary. Given that she earns 4% commision on all sales, let the sale she needs to make to get $2,000 be S, then 4 / 100 x S = 2000 this gives 0.04S = 2000 giving that S = 2000 / 0.04 = 50,000. Therefore, Tamara needs to make a sales of $50,000 to be able to earn $6,000 this month.</span>
Answer:
Yes, the graph represents a proportional relationship. No, the graph does not represent a proportional relationship. It is a straight line, but it does not intersect the point (0, 0).
(x,y)
(-1,4)
y=4
the equation is y=4 because the slope is actually undefined
y=2 is paralell to y=4
euation is y=4
Answer:
$3.98
Step-by-step explanation:
To answer this, we can use simple division and multiplication.
Using the example of 2 pounds is equal to $7.96:
If 2 pounds = $7.96, then...
1 pound = ($7.96) divided by 2
1 pound = $3.98
Using the example of half a pound is equal to $1.99:
If 0.5 pounds = $1.99, then...
1 pound = ($1.99) x 2
1 pound = $3.98
