Answer:

$F = 1.8C + 32$

Step-by-step explanation:

Given

The attached table

Required

The relationship between both temperatures

<em>This implies that we calculate the table equation</em>

First, we calculate the slope (m)

$m = \frac{F_2 - F_1}{C_2 - C_1}$

Where:

$(C_1,F_1) = (0,32)$

$(C_2,F_2) = (20,68)$

So, we have:

$m = \frac{68 - 32}{20 - 0}$

$m = \frac{36}{20}$

$m = 1.8$

The equation is then calculated using:

$F = m(C - C_1) + F_1$

This gives:

$F = 1.8(C - 0) + 32$

$F = 1.8(C ) + 32$

$F = 1.8C + 32$

What is the area of the sector of the circle below, if the radius is 5 m. and the central angle < AOB measures 88 °. (round a

MariettaO [177]

Answer:

b 19.2

Step-by-step explanation:

a = $\pi$ $r^{2}$ for a circle. We do not want to find the area for a whole circle. We only want to find the area for part of a circle. a hole circle is 360 degrees.

a = $\frac{88}{360}$ $\pi$ $r^{2}$

a = $\frac{88}{360}$ $\pi$ ( $5^{2}$ )

a = 19.2 rounded.
