Answer:

  • x - 4

Step-by-step explanation:

  • V(x) = x³ - 8x² + 19x - 12

<u>The two of the dimensions given</u>

  • (x - 1) and (x - 3)

<u>and the third one is</u>

  • x + a

<u>Multiply the three dimensions to get the volume:</u>

  • (x - 1)(x - 3)(x + a) =
  • (x² - 4x + 3)(x + a) =
  • x³ - 4x² + 3x + ax² - 4ax + 3a =
  • x³ - (4 - a)x² + (3 - 4a)x + 3a

Comparing with the given function, we get a = - 4

<u>So the missing dimension is:</u>

  • x - 4

Answer:

  1.1.1  sin(241°) = -√t

  1.1.2  cos(61°) = √(1 -t)

Step-by-step explanation:

<u>Given</u>:

 sin(61°) = √t

<u>Find</u>:

  1.1.1  sin(241°)

  1.1.2  cos(61°)

<u>Solution</u>:

1.1.1  sin(180° +x) = -sin(x)

  sin(241°) = -sin(61°) = -√t

__

1.1.2  cos(x) = √(1-sin²(x))

  cos(61°) = √(1 -(√t)²) = √(1 -t)

Amy drives 300 miles from London to Newcastle.
WARRIOR [948]

Amy's average speed during her whole journey from London to Newcastle (300 miles) was 51.422 miles per hour.

<h3>How to calculate the average speed?</h3>

This is calculated by taking the total distance and dividing it into the total time.

<h3>What was Amy's average speed?</h3>

First part of ther journey: 165 miles at 60mph, which is equal to 2.75 hours

  • Time: distance/speed
  • Time: 165 miles/ 60 mph= 2.75 hours

Second part of her journey: 135 miles in 3.083 hours (3 hours and 5 minutes)

  • Total distance: 300 miles
  • Total time: 2.75 hours + 3.084 = 5.834

Average speed: 300 miles / 5.834 = 51.422 miles per hour
