Are (2,9) and (-3,-6) both on the line y = 4x + 6? If not, find an equation for the line that does pass through both points.

igor_vitrenko [27]

Answer:

no, y=3x+3

Step-by-step explanation:

plug both points into the equations:

9=4*2 +6 -> 9=8+6, doesn't work
-6=4(-3)+6 -> -6=-6, works

one works but the other doesn't so now we find a line through both points

use the formula (y_2-y_1)/(x_2-x_1) to find the slope:

(-6-9)/(-3-2)=-15/-5=3

y=3x+b, plug in a point to find b:

9=3(2)+b
9=6+b
b=3
y=3x+3

What is the area of a 320 ft semicircle?

Sever21 [200]

Answer: they do not have enough info but I will try my best to answer if im wrong its not my fault so please add more info

Solution

2. I know that for a Semi-Circle Area = 320 . From this find out Area of the Semi-Circle.

Solution:

Here Area=320(Given)

Area=

πr2

r2=

Area⋅2

r2=

320⋅2

r=14.2701

Diameter(d)=2r

=2⋅14.2701

=28.5402

Circumference=πr

⋅14.2701

=44.849

Perimeter=πr+2r

⋅14.2701+2⋅14.2701

=44.849+28.5402

=89.6979

The circle below has center k , and its radius is 3 cm Given that m∠LKM =70° , find the length of the major arcLNM

Veseljchak [2.6K]

The length of the major arc LNM is $\frac{29}{6}\pi \ cm$

<h3><u>Length of an arc</u></h3>

From the question,

We are to determine the value of the length of the major arc LNM

The length of the major arc LNM can be calculated using the formula

$Length \ of \ major\ arc \ LNM = \frac{Reflex \$

Where r is the radius

First, we will determine the value of the reflex ∠LKM

Reflex ∠LKM + ∠LKM = 360° (<em>Sum of angles at a point</em>)

From the given information,

∠LKM = 70°

Then,

Reflex ∠LKM + 70° = 360°

Reflex ∠LKM = 360° - 70°

Reflex ∠LKM = 290°

Also, from the question

r = 3 cm

Now, putting the parameters into the formula, we get

$Length \ of \ major\ arc \ LNM = \frac{290 ^\circ }{360 ^\circ} \times 2\pi \times 3$

Then,

$Length \ of \ major\ arc \ LNM = \frac{1740\pi}{360}$

$Length \ of \ major\ arc \ LNM = \frac{29}{6} \pi \ cm$

Hence, the length of the major arc LNM is $\frac{29}{6}\pi \ cm$
