What is the length of the arc shown in red?

professor190 [17]

Answer:

≈ 18.8 cm

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

The central angle is equal to the arc subtending it, that is 60°

arc = 2πr × $\frac{60}{360}$

= 2π × 18 × $\frac{1}{6}$

= 36π × $\frac{1}{6}$

= 6π ≈ 18.8 cm ( to 1 dec. place )

What is the general form of the equation of the line shown?

Nostrana [21]

Hey There!

The formula of the general form equation is

0 = Ax + By + C

As we look at the answer choices we see that the last choice best represents the correct answer.

x + y + 2 = 0

Best matches the formula given and therefore that would be the correct answer.

Thus, the answer would be x + y + 2 = 0

Graph f(x) = 2x^4+3 <br> let x = 0, 1, and 2.<br> please show your work

mestny [16]

Sub those points for x
f(x) is the y

(x,y)

so for x=0
f(0)=2(0)^4+3
f(0)=0+3
f(0)=3
(0,3) is a opint

for x=1
f(1)=2(1)^4+3
f(1)=2(1)+3
f(1)=2+3
f(1)=5
(1,5) is another point

for x=2
f(2)=2(2^4)+3
f(2)=2(16)+3
f(2)=32+3
f(2)=35
(2,35) is another point

points are
(0,3)
(1,5)
(2,35)
