Answer:

The figure can be separated into a right angled triangle and a rectangle

Step-by-step explanation:

To find the base of the triangle, you subtract 4/3 ft from 5 ft...hence, the base is 3.67 ft

Area of the triangle = 1/2 (Base x Perpendicular height)

= 1/2(3.67 x 2)

= 3.67ft^2

Area of rectangle = Length x Width

= 4/3 x 1/3

= 0.44ft^2

Total area = area of rectangle + area of triangle

= 0.44ft^2 + 3.67ft^2

= 4.114ft^2

Find the factorization of the polynomial

makvit [3.9K]

There is only one real root, at x=-2, so the polynomial describing this parabola has factors of (x+2) with multiplicity 2. The y-intercept tells you the vertical stretch is 1.

The factorization is y = (x +2)².

I need help finding if it’s either SOH, CAH or TOA and the indicated side of the triangle, thank you!

Answer:

$\huge\boxed{IJ \approx 2.01}$

Step-by-step explanation:

In order to find the side mentioned (IJ), we need to use SOH CAH TOA.

SOH CAH TOA is an acronym to help us remember what sin, cos, and tan mean. It stands for:

Sin = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tan = Opposite / Adjacent

Since we know the measure of angle K (42) and we know one of the sides, we can use this to find the missing length.

Since the side given to us is the hypotenuse, and we're looking for the side opposite of the angle (IJ), the only possible one to use would be SIN as it includes Opposite and Hypotenuse.

Our equation is now this: $\text{sin(42)} = \frac{x}{3}$
