A projectile is fired upward from the ground with an initial velocity of 300 feet per second. Neglecting air resistance, the hei

ght of the projectile at any time t can be described by the polynomial function P(t) = ­16t 2 + 300t

Answer: The polynomial that describes the projectile's height is:

P(t) = - ­16t*2 + 300t

For t = 1 second we have:

P(1) = - 16*1^2 + 300*1

P(1) = 284 ft

The height of the projectile after 1 second is 284 feet.

kodGreya [7K]

Answer:

9/34

Step-by-step explanation:

P(QnR) = P(Q) * P(R)

= 12/17 * 3/8

= 9/34

stepladder [879]
So first you would divide 3,600 by 420. You should get the answer of 8. Then multiply 8 by 12 to get the total number of gallon needed, which is 96 gallons.

Which of the following ordered pairs is a solution of x + 1/2y = 1?
pogonyaev

(-2,6)

for example  

x+1/2y=1  

the ordered pair i will use is the first one. (-2, 6)  

so  

(-2) + 1/2(6)=1  

from there it is a simple add/subtract and multiply/divide math problem.  

1/2(6)=3  

so  

(-2) + 3 = 1  

yes this ordered pair works for the solution meaning it is the answer.

Consider the line y = 1/4 - 5/4 x<br> Slope of a parallel line<br> Slope of a perpendicular line
gladu [14]

Answer:

parallel line slop2 = -5/4

perpendicular line slope = 4/5

Step-by-step explanation:

If 2 lines are parallel, they will have equal slopes.

Therefore, the slope of a line parallel to y = 1/4 - 5/4 x will be -5/4

If 2 lines are perpendicular, their slopes are negative reciprocals of each other.  So the slope of the perpendicular line = -1 ÷ -5/4 = 4/5
