Answer:
<h3>YES</h3>
Step-by-step explanation:
Given the position of the particle expressed using the expression;
x(t)= 5t^3 - 9t^2 + 7 where;
x moves along the positive x-axis
when t = 1
x(1) = 5(1)^3 - 9(1)^2 + 7
x(1) = 5 - 9 + 7
x(1) = -4 + 7
x(1) = 3
<em>Since the position of the particle is positive at t = 1, hence the particle is moving towards the right at time t = 1</em>

Step-by-step explanation:sorry if wrong
The window has a shape of a semi-circle (half of a circle).
We know the diameter d = 12 ft.
The area of a (complete) circle is given by the formula:
A = π × r²
The radius can be found by halving the diameter:
r = d ÷ 2
= 12 ÷ 2
= 6 ft
Therefore the area of the circle will be:
<span>A = π × r²
= 3.14 × 6</span>²
= <span>3.14 × 36
= 113.04 ft²
And the area of the semi-circle:
A = </span><span>113.04 </span>÷ 2
= 56.52 ft²
Hence, the area of the window will be 56.52 ft².
