Answer:
The domain of f is {x : x ∈ R, -7 ≤ x ≤ 7} ⇒ [-7, 7]
Step-by-step explanation:
<em>The domain of a function is </em><em>all the values of x</em><em> make the function defined</em>
In the given graph
∵ The graph drawn from x = -7 to x = 7 and from y = -6 to y = 4
→ That means the values of x started from -7 and ended at x = 7
∵ The coordinates of the starting point of the graph of f are (-7, -5)
∵ The coordinates of the ending point of the graph of f are (7, 3)
∴ -7 ≤ x ≤ 7
∵ Values of x are the domain of the function
∴ The domain of the function is -7 ≤ x ≤ 7
∴ The domain of f = {x : x ∈ R, -7 ≤ x ≤ 7} ⇒ [-7, 7]
Answer:
2 hrs and 21 mins I think
Step-by-step explanation:
I subtracted 328-147 and got 181 and since their is 60 mins in one hr I made it another hour and after I subtracted 81-60 and got 21 minutes. 2 hrs and 21 mins. Hope this makes sense.
Answer:
The answer to your question is V = 82.5 in³
Step-by-step explanation:
Data
V = BH
a = 2.75 in
side = 4
height = 3 in
Process
1.- Calculate the area of the base (B)
B = Pa/2
P = number of sides x length of a side
= 5 x 4
= 20 in
B = (20)(2.75)/2
B = 55/2
<u>B = 27.5 in</u>
2.- Calculate the volume of the prism
V = (27.5)(3)
<u>V = 82.5 in³</u>
Fencing means perimeter so that mean 2 times the length + 2 times the width.
Kelly has 240 feet of fencing and the width is 20 feet. So 240 = 2 lengths + 2 widths. So we have to multiply the width by 2 and subtract it from 240. 20x2 = 40. Now 240-40 = 200. So we are left with 200 feet of fencing for the length. Since we have to multiply the length by 2 in the perimeter, we can divide 200 by 2 to get the length. 200/2 = 100. So the length of the fence is 100 feet. Hope this helps and if so please leave a good rating and thanks and maybe even brainliest answer. Thank you I really appreciate it. Have a nice day!
