well, looking at the picture, coming from the right, namely lim -> 3⁺

starts off at 0 when x = 5, then as "x" moves to the left, it starts to go down and down and down, we have a dashed lilne at that section, namely is an asymptote, so there's a vertical asymptote at x = 3, which means that line keeps on going down to -∞.

now, coming from the left, namely lim -> 3⁻, starts off at 2 as "x" moves to the right it is going down and down and down towards the asymptotic line, so then coming from the left the limit is also -∞.

so one can say that \bf \lim\limits_{x\to 3}~ f(x) = -\infty, or it does not exist.

Answer:

7.3 feet

Step-by-step explanation:

osK=

hypotenuse

adjacent

​

=

35

x

​

\cos 78=\frac{x}{35}

cos78=

35

x

​

35\cos 78=x

35cos78=x

Cross multiply.

x=7.2769\approx \mathbf{7.3}\text{ feet}

x=7.2769≈7.3 feet

Type into calculator and round to the nearest tenth of a foot.

Soloha48 [4]

Answer:

13.73 sq mm

Step-by-step explanation:

Area of Square - Area of Circle = Area of Shaded Region

if radius of circle is 4 then diameter is 8

the diameter is the same as the length of each side of the square

so area of square = 8² or 64

Area of Circle = 16π

64 - 16π ≈ 13.73
