Answer:

y-int = +5

Step-by-step explanation:

Sum and Diff is just saying add up all like terms then plug in 0 into the x terms to get y. It's actually a lot easier than you think.

Suppose Neil Armstrong decided to throw a golf ball into the air while he was standing on the
lawyer [7]

Answer:

At 7 seconds the instantaneous rate of change of the function s(t) with time which is the velocity is -11.18 m/s

Step-by-step explanation:

The given information on the height can be written as follows;

s(t) = -2.72·t² + 26.9·t + 6

Where;

s = The height (displacement) of the golf ball

t = The time taken during the motion of the golf ball

The velocity is found by finding the derivative of the displacement s as follows;

v = d(s(t))/dt = d(-2.72·t² + 26.9·t + 6)/dt = 2×(-2.72)×t + 26.9

When t = 7, v = 2×(-2.72)×7 + 26.9 = -11.18 m/s

Therefore the ball is coming down with 11.18 m/s speed at 7 seconds.

The sum of the angle measures of the polygon is 540°. Write and solve an equation to find the value of 2.
kifflom [539]

Answer:

x = 29°

The angles are  137° , 116° , 96° , 44° and 147°

Step-by-step explanation:

The sum of the angles of the polygon is given as 540°. The angles are given as 5x – 8°,  4x° , 96° , 44°, 5x + 2. Therefore, the value of x can be found as follows

5x – 8° + 4x°  + 96° + 44° + 5x + 2° = 540°

collect like terms

5x + 4x + 5x - 8 + 96 + 44 + 2 = 540°

14x + 134 = 540°

14x = 540 - 134

14x = 406

divide both sides by 14

x = 406/14

x = 29°

Therefore, the angles are as follows

29 × 5 - 8 = 137°

29 × 4 = 116°

96°

44°

5 × 29 + 2 = 147°

Which of the following describes the correct process for solving the equation 2x − 4 = 20 and arrives at the correct solution? A
Gelneren [198K]

Answer:

<u>The correct answer is A. Add 4 to both sides, and then divide by 2. The solution is x = 12.</u>

Step-by-step explanation:

1. For solving the question and understand which of the statements matches with the solution, let's proceed with the equation:

2x − 4 = 20

2x  - 4 + 4 = 20 + 4 (Adding 4 at both sides)

2x = 24

2x/2 = 24/2 (Dividing by 2 at both sides)

x = 12

<u>The correct answer is A. Add 4 to both sides, and then divide by 2. The solution is x = 12.</u>
