Answer:

\red{{7}^{15} }

Step-by-step explanation:

We know that,

{x}^{a}  \times  {x}^{b}  =  {x}^{a + b}  \\ ( {x}^{a} ) ^{b}  =  {x}^{ab}

Accordingly,

( {7}^{5} ) ^{3}  \\  {7}^{5 \times 3}  \\  {7}^{15}

. Megan is standing 300ft from the Eiffel Tower. The Eiffel Tower is 900 ft tall.
MAVERICK [17]

9514 1404 393

Answer:

  about 71.6°

Step-by-step explanation:

The relevant trig function is ...

  Tan = Opposite/Adjacent

Here, the "opposite" side of the right triangle is the height of the tower. The "adjacent" side is the distance to the tower. Then if the angle is x, we have ...

  tan(x) = 900/300 = 3

  x = arctan(3) ≈ 71.6°

Megan's angle of elevation is about 71.6°.

Answer:

x = 85°

Step-by-step explanation:

Because the sum of the angles in a triangle is 180°, we can find ∠CDB.

180° - ∠CBD - ∠BCD = ∠CDB.

180° - 35° - 50° =

180° - 85° =

95°

So, ∠CDB is 95°

Then, because a line has 180°, we can find ∠CDA.

180° - ∠CDB = ∠CDA.

180° - 95° = 85°

So, x = 85°

Use the T-table below to determine 3 solutions to this equation: y = 2x
Jet001 [13]
The table is attached as a figure

The given equation is ⇒⇒⇒⇒ y = 2x
To solve this equation, we need to pick numbers from the table then this number will be substituted into the equation to find y
we need 3 solutions . so, we need to pick 3 numbers of x
From the table, let us choose x = 0
y = 2x
y = 2 * (0)
y = 0

From the table, let choose second value of x such as x = 1
y = 2 * (1)
y = 2

From the table, let choose third value of x such as x = -1
y = 2 * (-1)
y = -2

So, the picked three solutions are
y = 0  at   x = 0
y = -2  at  x = -1
y = 2 at  x = 1
