Answer:

Option A is the correct option.

Step-by-step explanation:

${a}^{2} + {b}^{2} - 2ab \: \cos \: c \: = {c}^{2} \\ a = 4 \\ b = 5 \\ c = 2 \\ \\ 2ab \: cos \: c = {a}^{2} + {b}^{2} - {c}^{2} \\ \: \: \: \: \: \: \: \: = {(4)}^{2} + {(5)}^{2} - {(2)}^{2} \\ \: \: \: \: \: \: \: \: = 16 + 25 - 4 \\ \: \: \: \: \: \: = 41 - 4 \\ \: \: \: \: \: \: = 37$

Hope this helps...

Good luck on your assignment...

If 1 centimeter on the scale drawing represents 2 feet, what will be the diameter of Clarise's fish pond?

alexandr402 [8]

Okie, so, each cm that measures across the pond is equivalent to 2ft
1cm=2ft
so if we have 3 cm
we would do 3x2
3x2=6

The diameter of the pond is 6 ft<span />

The vertex of this parabola is at (-4,-1).When the y-value is 0,the x-value is 2.What is the coefficient of the squared term in

densk [106]

Answer:

1/36

Step-by-step explanation:

When the coefficient is 1, the function has zeros at -3 and -5, one horizontal unit from the vertex. You want to move the zero to (2, 0), which is 6 units from the vertex. To achieve a horizontal stretch by a factor of 6, the value of x in the function must be replaced by x/6. That would make the coefficient of x^2 be (1/6)^2 = 1/36.

The coefficient of the squared term is 1/36.
