Answer:

Step-by-step explanation:

Area of two circles = 2*πr² = 2*3.14 * 6 * 6 = 226.08 square units

Area of rectangle = length * width = 24 * 12 = 288 square units

Area of shaded region = Area of rectangle - area of two circles

= 288 - 226.08

= 61.92

= 62 square units

Answer:

$h(t) = 0.75t^2 + 4t + 12$

Step-by-step explanation:

The equation given calculates the derivative of the height in relation to the time, that is, the rate of change of the height. To find the equation for the height, we need to integrate this equation:

$dh/dt = 1.5t + 4$

Multiplying both sides by 'dt', we have:

$dh = (1.5t + 4)dt$

Using the integral in both sides:

$\int dh = \int (1.5t + 4) dt$

$h = 0.75t^2 + 4t + h(0)$

$h = 0.75t^2 + 4t + 12$

So the height after t years is represented by this equation:

$h(t) = 0.75t^2 + 4t + 12$

Solving equations:<br><br> (a) 5x - 9 = 3x + 3<br><br> (b) x + 6 = 34 - x

Jet001 [13]

Answer:

a) 5x - 9 = 3x + 3

5x - 3x = 3 + 9

2x = 12

x = 12 / 2

x = 6

b) x + 6 = 34 - x

x + x = 34 - 6

2x = 28

x = 28 / 2

x = 14

To divide fractions, you multiply by the reciprocal of the second fraction.

kicyunya [14]

This is true.

Example:

= 8/9 ÷ 7/3
to divide fractions, multiply by the reciprocal/inverse of 7/3

= 8/9 * 3/7

= (8*3)/(9*7)
multiply numerators; multiply denominators

= 24/63
simplify

= 8/21

ANSWER: This is (A) true

Hope this helps! :)

Complete the comparison: 2+7>? a. 9+4 b. 7+3 c. 10-2 d. 8+2

Zina [86]

The answer is c because 2+7=9 and 10-2=8 and 9 is greater than 8 so 2+7>10-2
