Answer:

Option B, $3.27$

Step-by-step explanation:

Given -

The submerged vessel travel horizontal distance above the shipwrecked hull

$= 400$

$= 0.4$ kilometers

The vertical distance from the the shipwrecked hull to the ground is equal to $7$ kilometers

There forms a right angled triangle with

Base $= 7$ kilometer

Perpendicular $=$ 0.4 kilometer

Tan (angle) $= \frac{Perpendicular}{Base}$

Substituting the given values we get -

Angle of depression

$= tan^{-1}(\frac{0.4}{7})\\= 3.27$

Hence, option B is correct.

Which is the graph of x Greater-than-or-equal-to 98.6? A number line going from 95 to 103. A closed circle is at 98.6. Everythin

Afina-wow [57]

Answer:

The correct option is;

A. A number line that goes from 95 to 103. A closed circle is at 98.6. Everything to the right is shaded.

Step-by-step explanation:

To represent x greater-than-or-equal-to 98.6 on the number line we note that an open circle stands for either a less than or a greater than, while an open circle stands for either less than or equal to or greater than or equal to

The correct way to represent x greater than or equal to 98.6 on the number line, we indicate the point 98.6 with a closed circle and we shade everything in the region of the solution which is to the right of the closed circle

Therefore the correct option is A. A number line that goes from 95 to 103. A closed circle at is at 98.6. Everyting to the right is shaded.

The coordinates of the vertices of AJKL are J(-5, -1), K(0, 1), and L(2, -5).

dalvyx [7]

We need slope of all lines ?

J(-5,-1)
K(0,1)
L(2,-5)

Slope of JK:-

$\\ \sf\longmapsto m=\dfrac{1+1}{0+5}=\dfrac{2}{5}$

Slope of KL:-

$\\ \sf\longmapsto m=\dfrac{-5-1}{2-0}=\dfrac{-6}{0}=-3$

Slope of JL

$\\ \sf\longmapsto m=\dfrac{-5-1}{2+5}=\dfrac{-6}{7}$

I ready scientific notation help

Airida [17]

The required value is $2\times10^9$

Step-by-step explanation:

Weight of ants = $4\times10^{-3}$

Weight of elephant= $8\times10^6$

We need to find, the total weight of about how many ants equals to the weight of an oversized elephant.

The equation given is:

$4\times10^{-3} \times a = 8\times10^6$

We need to find a:

Solving:

$4\times10^{-3} \times a = 8\times10^6\\a=\frac{8\times10^6}{4\times10^{-3}}\\if \,\,10^a/10^-b \,\,then\,\, 10^{a+b}\\a=2\times10^{6+3} \\a=2\times10^9$

So, the required value is $2\times10^9$
