Step-by-step explanation:

Using the ratio equality for circles

$\frac{arc}{C}$ = $\frac{angleatcentre}{360}$

(a)

Note the angle at the centre of the shaded arc is 360° - 90° = 270°, thus

$\frac{45}{C}$ = $\frac{270}{360}$ = $\frac{3}{4}$ ( cross- multiply )

3C = 180 ( divide both sides by 3 )

C = 60 mm

(b)

Note the angle at the centre of the shaded arc is 360° - 135° = 225°, thus

$\frac{3.3}{C}$ = $\frac{225}{360}$ ( cross- multiply )

225C = 1188 ( divide both sides by 225 )

C = 5.28 cm

the price of a technology stock was $9.53 yesterday. Today, the price rose to $9.66. Find the percentage increase. Round your an

galben [10]

So, 9.66 - 9.53 will then be 0.13, so if we take 9.66 to be the 100%, what is 0.13 off of it in percentage then?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
9.66&100\\
0.13&p
\end{array}\implies \cfrac{9.66}{0.13}=\cfrac{100}{p}\implies p=\cfrac{0.13\cdot 100}{9.66}$

Select all the correct answers. Which statements are true about function g? NO LINKS!!!

Anna35 [415]

Answer:

A, B, E

Step-by-step explanation:

The attachment shows a graph of the function. It tends to infinity for x going to infinity in either direction. (A, B are true)

The right-side piece is cubic, not quadratic.

The U-shape tells you the function is decreasing on the left side.

The two function definitions have the same value at x=2, so the function has no discontinuities. It is continuous. (E is true)
