snail travels at a rate of 2.37 feet per minute. write a route to describe the function how far will the snail travel in six min

Alex

F(x)=2.37ft*(X)
if x=6
then you multiply the amount of feet per minute which is 2.37 by 6
2.37*6=14.22
so your answer would be 14.22

Find the area of the shaded figure. To do so, subtract the area of the smaller

Vikentia [17]

Answer:

x⁴ - 8x² + 9

Step-by-step explanation:

The Area of the smallest square is A1 = x . x = x²

The Area of the second square is A2 = ( x² - 3 )(x² - 3)

A2 = x⁴ - 3x² - 3x² + 9

A2 = x⁴ - 6x² + 9

The Area of the Shaded shape is A2 - A1

x⁴ - 6x² + 9 - x²

x⁴ - 8x² + 9

Answer:

x ≈ 77°, y = 103°

Step-by-step explanation:

Using the Sine rule in Δ BCD

$\frac{2.9}{sin45}$ = $\frac{4}{sinx}$ ( cross- multiply )

2.9sinx° = 4sin45° ( divide both sides by 2.9 )

sinx° = $\frac{4sin45}{2.9}$ , thus

x = $sin^{-1}$ ( $\frac{4sin45}{2.9}$ ) ≈ 77° ( to the nearest degree )

Since AC and DC are congruent then Δ ACD is isosceles.

Thus the base angles are congruent, that is

∠ ADC = ∠ CAD = y°

x and y are adjacent angles and supplementary, thus

x + y = 180, that is

77 + y = 180 ( subtract 77 from both sides )

y = 103°
