Which of the following inequalities does the graph represent?

Mathematics
1 answer:
Romashka-Z-Leto [24]3 years ago
4 0

For this case we must indicate the inequality represented in the graph.

It is noted that we have a closed point at -1, so the inequality at that point contains equality and is represented by "[". On the other hand, we observe an open point at +3, so inequality does not include equality (does not include +3) and is represented as ")".

So, the interval of the graph is:

[-1,3)

This is equivalent to:

-1 \leq t

Answer:

Option B

Two ships leave the same port in different directions, forming a 120° angle between them. One ship travels 70 mi. and the other
kondaur [170]

Answer : Distance between the ships to the nearest miles = 106.03 ≈ 106 mi.

Explanation :

Since we have shown in the figure below :

a=70 mi.

b=52 mi.

c=x mi.

\text{Since two ships leaves the same port in different directions forming a }120\textdegree\text{angle between them.}

So, we use the cosine rule , which states that

 c^2=a^2+b^2-2ab.cosC\\\\x^2=70^2+52^2-2\times 70\times 52\times cos(120\textdegree)\\\\x^2=4900+2704-7280\times (-0.5)\\\\x^2=7604+3640\\\\x^2=11244\\\\x=\sqrt{11244}\\\\x=106.03

So, c = x= 106.03 mi.

Hence, distance between the ships to the nearest miles = 106.03 ≈ 106 mi.

Help me with number 2 I need help fast with the right answer with showing work
Anvisha [2.4K]

Volume of a cylinder is defined as:

v = volume

r = radius

h = height.

V = \pi(r^2)h

In this problem,

v = 1,356.48 in^3

r = 6 in

h = ?

Plug our numbers into the volume formula above.

1,356.48 in^3 = \pi(6^2)h

Divide both sides by \pi(6^2) to isolate variable h

12.0 = h

The height of the cylinder is 12.0 inches
