Examine whether x-1 is a factor of the polynomial 4x³+3x²-4x+3​

Mathematics
1 answer:
Yuki888 [10]4 years ago
4 0

Answer:

x - 1 is not a factor.

Step-by-step explanation:

By the Factor theorem if  x - 1 is a factor then f1) = 0:

f(1) = 4*1^3 + 3*1^2 - 4*1 + 3

=  4 + 3 - 4 + 3

= 6 so it is not a factor.

Solar panels installed in a backyard have a cross section that is a right triangle. The diagram shows the approximate dimensions
Citrus2011 [14]

Answer:

About 4.2 ft

Explanation:

The area of the traingle can be calculated in two ways.

A=\frac{1}{2}\text{width}\cdot\text{length}

where width = 4.4 ft and length = 13.6 ft.

Putting in the values for width and length gives

\begin{gathered} A=\frac{1}{2}13.6\cdot4.4_{} \\ \boxed{A=29.92ft^2} \end{gathered}

The other way that the area can be calculated is

A=\frac{1}{2}\cdot\text{height}\cdot\text{base}

where height = vertical length and base = 14.3 ft; therefore.

\begin{gathered} A=\frac{1}{2}14.3h \\ A=7.15h \end{gathered}

This must equal the area of the triangle we found above; therefore,

A=29.92=7.15h29.92=7.15h

dividing both sides by 7.15 gives

h=\frac{29.92}{7.15}\boxed{h\approx4.2ft}

which is our answer!
