Answer:

The money he makes mowing lawn can be represented by a linear function.

The function can be represented in the slope-intercept form.

the equation of the function is y=500+10x

where

y=amount of money he has earned by mowing lawns.

x=number of lawn mowing clients he has.

Step-by-step explanation:

It can be represented by a linear function (straight line) because the <em>additional</em> amounts are proportional to the number of clients he has.

The equation is

y=500+10x

where

y=amount of money he has

x=number of lawn mowing client he has.

Georgia [21]

Answer:

$\approx 116 \: {cm}^{2}$

Step-by-step explanation:

Radius of the internal circle $r_1=2.3 \: cm$

Radius of the external circle $r_2=6.5 \: cm$

Area of the shaded region = Area of external circle - Area of internal circle.

$= \pi r_{2}^{2} - \pi r_{1}^{2} \\ \\ = \pi \{ r_{2}^{2} - r_{1}^{2} \} \\ \\ = \pi \{ (6.5)^{2} - (2.3)^{2} \}\\ \\ = 3.14\{ (6.5 + 2.3) (6.5 - 2.3) \}\\ \\ = 3.14\{8.8 \times 4.2 \}\\ \\ = 116.0544 \\ \\ \approx 116 \: {cm}^{2}$

James has mapped his seat and his teacher's seat on the coordinate plane at (0,10) and (–4,6). Find the distance between their s

wlad13 [49]

Answer:

Distance between their seats is 4√2 units.

Step-by-step explanation:

We are given that James mapped his seat and teacher's seat at (0,10) and (-4,6) on the coordinate plane.

So, distance between their seats= distance between the points (0,10) and (-4,6)

= $\sqrt{(-4-0)^{2}+(6-10)^{2}}$

= $\sqrt{(-4)^{2}+(-4)^{2}}=\sqrt{16+16}$

$=\sqrt{32}=4\sqrt{2}units$
