A child releases a balloon from a height of 9.2 feet above the ground. It begins to rise at a steady rate of 3.8 feet per second. Let t be the time the balloon has been rising in seconds since it was let go. (a) How high is the balloon above the ground after 10 seconds?

circumference divided by 3.141592654 then timesthe radius twice

step-by-step explanation:

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
