What are the two sides that form the right angle of a right triangle called?

Answers

right triangle
the long side (the diagonal side, the side oposite the right angle) is hypotnuse

the side ones ar the legs

answer is the legs
since the hyptonuse is oposite the right angle, it cannot help form it

answer is the legs

From the top of a lighthouse 180 feet high, the angle of depression of a boat is 23o. Find the distance from the boat to the foot of the lighthouse to the nearest foot. (The lighthouse was built at sea level.)

Answers

Answer:

The lighthouse is 424 feet away.

Step-by-step explanation:

There is no other way to do this but to use one of the 6 trigonometry functions.

Drawing

Draw a dotted horizontal line.

judge an angle that could be 23o. Let it slant downward from the left side of the dotted line.

Draw another horizontal line that represents sea level.

Join the left side of the dotted line to the last line you drew. The angle on your right is also 23o.

Function

You have 6 trig functions to choose from. You have the lighthouse height (180 feet) the angle on your right, and the length on the horizontal representing the distance from the lighthouse base to the boat.

You have an angle

You have an opposite side

You have a horizontal line (the adjacent side)

You want to use the tangent function.

Tan(23) = opposite / ad

Tan(23) = 180 / adjacent Multiply both sides by the adjacent

adjacent*Tan(23)= 180 Divide by Tan(23)

adjacent = 180/Tan(23)

adjacent = 180 / 0.42447

adjacent = 424 feet.

Hi my math teacher makes my life impossible and I have no clue how to do this thanks!

Answers

the answer is x^3 (when you have product of powers you just add them.).

Answer:

x3, because when you have the powers (in x6, the "6" is the power) then you add the powers. x3 + x6 = x9. So your answer is x3.

If the circumference is 12 pi what is the diameter

Answers

So,

The formula for the circumference of a circle:
$C = 2 \pi r\ or\ C = \pi D (diameter)$

We can now substitute the given values and solve for D.
$12 \pi = \pi D$

Divide both sides by pi.
$12 = D$

The diameter of the circle is 12 units.

well, since the equation for circumference is $2 \pi r^(2)$ and the diameter is double the radius, the diameter will end up being about 3.82

Baxter wants to make 1 1/2 time the recipe. Will he need more or less sugar than Violet needs if she doubles the recipe?

Answers

Baxter will need less since Violet will double the recipe. Double means Violet wants to make 2 times the recipe. 1 1/2 is less than 2.

Which of the following could represent the graph of f(x) = x4 + x3 – 8x2 – 12x?

Answers

The graph (B) represents the polynomial function f(x) = x⁴ + x³ – 8x² – 12x because the graph intersect at 0, -2, and 3option (B) is correct.

What is polynomial?

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

$\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n$

We have a polynomial function:

f(x) = x⁴ + x³ – 8x² – 12x

First, find the roots or zeros of the polynomial.

Using the factorization method:

We can write the above polynomial as:

f(x) = x(x³ + x² - 8x - 12)

f(x) = x(x + 2)(x + 2)(x - 3)

f(x) = x(x + 2)²(x - 3)

The zeros are:

x = 0

x = -2

x = 3

Thus, the graph (B) represents the polynomial function f(x) = x⁴ + x³ – 8x² – 12x because the graph intersect at 0, -2, and 3option (B) is correct.
