Mathematics

5 0

A:

Width of the deck = 2x+3 units

Length of the deck = 5x+6 units

So area of rectangular deck = Length * width

= (5x+6)(2x+3)

Area = 10x^{2}+15x+12x+18

Area= 10x^{2}+27x+18 units square

As mentioned in part B, the area of the pool is 3x^{2}+7x+6 so the combined area of the deck and pool is

Area = area of rectangular deck + area of pool

= 13x^{2}+34x+24 unit square


B:

The area of only the deck is 10x^{2}+27x+18 unit square

Y = mx + b
slope(m) = -5/3
(0,1/3)...x = 0 and y = 1/3
now we sub and find b, the y int
1/3 = -5/3(0) + b
1/3 = b

so ur equation is : y = -5/3x + 1/3 <== slope intercept form

or if u need it in standard form : 
y = -5/3x + 1/3
5/3x + y = 1/3 ...multiply by 3
5x + 3y = 1 <== standard form

A professional baseball player hits a homerun on a .75kg baseball. The ball accelerated at a rate of 1200m/s2. How much force di
brilliants [131]

Answer:

The force the player hit the ball with is 900 N

Step-by-step explanation:

Given;

mass of the baseball, m = 0.75 kg

acceleration of the ball, a = 1200 m/s²

The force the player hit the ball with is given by the following equations;

F = ma (based on Newton's second law of motion)

where;

F is the applied force

m is mass of the baseball

a is the acceleration of the baseball

F = ma

F = (0.75 x 1200)

F = 900 N

Therefore, the force the player hit the ball with is 900 N
