Answer:

27in

Step-by-step explanation:

So, perimeter means we add all the sides together, as opposed to area, where we multiply them together.

9 - 5 = 4.

So the perimeter of the triangle would be:

3+4+ $\sqrt{3^2+4^2}$ =12

5 + 5 + 4 +1 (the 1 is from 4 -3) = 15

15 + 12 = 27

A submarine was traveling along the surface of the ocean and decides to dive. If the dive angle is 28° with the horizontal surfa

Alex_Xolod [135]

Answer:

1.5 nautical miles

Step-by-step explanation:

See the attached diagram.

The submarine starts to dive at point A and diving along AB.

If the distance traveled underwater i.e. AB = 1.7 Nautical miles and C is the point directly above its current position at B.

Then Δ ABC is a right triangle having ∠ BAC = 28° {Given}

So, using trigonometry we can write

$\cos 28 = \frac{AC}{AB} = \frac{AC}{1.7}$

⇒ $AC = 1.7 \times \cos 28 = 1.5$ nautical miles.

Therefore, the surface distance that the submarine travels is 1.5 nautical miles. (Answer)

In ΔUVW, w = 44 cm, u = 83 cm and ∠V=141°. Find the area of ΔUVW, to the nearest square centimeter.

Tema [17]

Answer:

$Area \approx 1149\ cm^2$

Step-by-step explanation:

<u>Given that:</u>

ΔUVW,

Side w = 44 cm, (It is the side opposite to $\angle W$ )

Side u = 83 cm (It is the side opposite to $\angle U$ )

and ∠V=141°

Please refer to the attached image with labeling of the triangle with the dimensions given.

Area of a triangle with two sides given and angle between the two sides can be formulated as:

$A = \dfrac{1}{2}\times a\times b\times sinC$

Where a and b are the two sides and

$\angle C$ is the angle between the sides a and b

Here we have a = w = 44cm

b = u = 44cm

and ∠C= ∠V=141

Putting the values to find the area:

$A = \dfrac{1}{2}\times 44\times 83\times sin141\\\Rightarrow A = \dfrac{1}{2} \times 3652 \times sin141\\\Rightarrow A =1826 \times 0.629\\\Rightarrow A \approx 1149\ cm^2$

So, the <em>area </em>of given triangle to the nearest square centimetre is:

$Area \approx 1149\ cm^2$

please help. will give brainliest! review the table of values for function p(x). what is lim (x -14) p(x), if it exists? (table

Lubov Fominskaja [6]

Answer:

DNE

Step-by-step explanation:

The the given table, we have;

As x approaches -14 from the left, at x = -14.001, p(x) = 1.96

$\lim \limits _{x \to -14^{-}} p(x) = 1.96$

As x approaches -14 from the right, at x = -13.999, p(x) = 1.97

$\lim \limits _{x \to -14^{+}} p(x) = 1.97$

The value of p(x) when x = -14 is $\lim \limits _{x \to -14} p(x)$ = Undefined, or is not definable, therefore, p(x) Does Not Exist (DNE) when x = -14, and we have;

$\lim \limits _{x \to -14} p(x)$ Does Not Exist, DNE.
