F(x) = -4x^7 +x^3 -x^2 +5
a) It is a degree 7 polynomial, so will have 7 zeros (some may be repeated).
b) has 3 sign changes, so 1 or 3 positive real zeros. If odd powers have their signs reversed, the signs are changed to +--+, so there are 2 sign changes. There will be 0 or 2 negative real zeros.
____
There is actually 1 positive real zero and 0 negative real zeros. This means there are 3 conjugate pairs of complex zeros.
Answer:
<h2>416m^2</h2>
Step-by-step explanation:
<h3>Area = Length * Width</h3><h3>Volume = Length * Width * Height</h3>
<h3>As we all can see,from the question we were given the parameters for calculating volume instead of the ones for calculating "area"</h3>
<h3>But from the the parameters, we can calculate for the total surface area</h3>
<h3>Floor = 12m ×10m = 120m^2</h3>
<h3>Roof = 12m × 10m = 120m^2</h3>
<h3>Front and back walls (x2) = 10m × 4m ×2 = 80m^2</h3>
<h3>Side walls (x2) = 12m × 4m × 2 = 96m^2</h3><h3>Total surface area</h3>
<h3>= 120m^2 + 120m^2 + 80m^2 + 96m^2</h3>
<h3>= 416 m^2</h3>
