R+9
Because Jessica rode 9 miles more than Roger, you would add 9 to Roger's number making the expression r+9
Answer:
C
Step-by-step explanation:
Both lines start and end on x = 3
The lower line has a positive slope and a y- intercept of - 2
The lower line has an open circle at it's endpoint indicating it cannot equal 3
x - 2 for x < 3
The upper line has a positive slope and a y- intercept of - 1, if we project the line. The line has a closed circle at it's start indicating it can equal 3, thus
x - 1 for x ≥ 3
Hence
x - 1 if x ≥ 3
x - 2 if x < 3 → C
The rate a which the surface area, S, decreases is
The surface area is
S = 4πr²
where r = the radius at time t.
Therefore
When r = 3 cm, obtain
![\frac{dr}{dt}]_{r=3} = - \frac{1}{3} \, cm/s](https://tex.z-dn.net/?f=%20%5Cfrac%7Bdr%7D%7Bdt%7D%5D_%7Br%3D3%7D%20%3D%20-%20%5Cfrac%7B1%7D%7B3%7D%20%5C%2C%20cm%2Fs%20%20)
Answer: -1/3 cm/s (or -0.333 cm/s)
Answer:
50.5
Step-by-step explanation:
Sooo first we calculate edf. 11/2= 5.5, 5.5x5=27.5
And then we do the other part.9/5=4, and 4x11.5=46, and we need to cut that in half cuz it’s a triangle 46/2=23. We add up the rectangle and the triangle: 27.5+23=50.5
Answer:
1
Step-by-step explanation:
Your answer is 1 because hundredths position is the second number after the decimal other answers include.
Ten=3
Ones place=8
Tenths place=7
Thousandths place=6
Hundred thousandths=5
Hope it helps have a great day:)
