Is (4, 5) a solution to 2y – 3x = -7?

Answers

Answer: no

because when (4;5) is a solution to 2y - 3x = -7

=> 2y - 3x = -7 passes through (4;5)

but when x = 4; y = 5 => 2.5 - 3.4 = -2 (unreasonable)

=> (4;5) isnt a solution

Write an algebraic expression for the phrase: 6 more than the product of 8 and n. ???

Answers

the product of 8 and n is 8•n, which can also be written as 8n. 6 more than that means you are adding 6, so your expression is

8n+6

The  algebraic expression for the phrase 6 more than the product of 8 and n can be dissected into terms. The term of the phrase the product of 8 and n is 8n. 6 more than this is equal to 6 + 8n. hence the answer to this problem is 6 + 8n. 

A ball is thrown vertically upwards from a height of 6 feet with an initial velocity of 40 feet per second. How high will the ball go? Note that the acceleration of the ball is given by feet per (second)2. Round your answer to the four decimal places.

Answers

Answer:

The maximum height that the ball reaches is sf = 31 feet from the ground

Step-by-step explanation:

Solution:-

- A ball is thrown vertically upwards from an initial elevation of si = 6 feet from the ground.

- The velocity with which the ball was thrown up, vi = 40 ft/s

- We can determine the maximum height of the ball when it is thrown vertically up by using the 3rd kinematic equation of motion.

                      vf^2 - vi^2 = 2*g*( sf - si )

Where,

vf : The final velocity of the ball, for maximum height it is = 0

sf : The final height of the ball from the ground

g : Gravitational constant = -32 ft/s^2

                      0 - 40^2 = -2*32*( sf - 6 )

                      sf - 6 = 25

                      sf = 31 feet

- The maximum height that the ball reaches is sf = 31 feet from the ground.
