What is a parabolic mirror?

This is also known as  paraboloid or paraboloidal reflector. It is a kind of  dish or a mirror that is said to have a reflective surface which is often used to take in or project any kind of energy e.g., light, sound, etc.

For the above question, the formula is:

y² = 2px

The focus is (p/2, 0)

x- 10 = u

y2 = 20u

So, the focus for U  =  ( [tex]\frac{20}{4}[/tex]; 0)

The focus for x =  ( [tex]\frac{20}{4}[/tex]; 10, 0)

= 5 , 10, 0

= (15, 0)

The area of the triangle below is 25.5 square inches. What is the length of the base?

Answers

Answer:

Step-by-step explanation

i have a triangle area calculator lol..

The length of the base of the triangle is B = 8.5 inches

What is a Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the area of the triangle be A = 25.5 inches²

Let the height of the triangle be H = 6 inches

Let the base of the triangle be B

Now , area of the triangle = ( 1/2 ) x Length x Base

On simplifying , we get

25.5 = ( 1/2 ) x ( 6 ) x ( B )

On simplifying , we get

3B = 25.5

Divide by 3 on both sides , we get

B = 8.5 inches

Hence , the base of triangle is B = 8.5 inches

Now solve for y

[tex]x=2y+1\\x-1=2y+1-1\\x-1=2y\\\frac{x-1}{2} =\frac{2y}{2}\\\frac{x-1}{2} =y[/tex]

Answers

Answer:

y = -x+10

Step-by-step explanation:

We have a point at ( 2,8) and a point at ( 4,6)

We can find the slope using

m = ( y2-y1)/(x2-x1)

   = ( 6-8)/ ( 4-2)

   = -2/2

  = -1

The slope is -1

We can see that it intercepts the y axis at 10 ( x=0 point)

Using the slope intercept form  y = mx+b  where m is the slope and b is the y intercept

y = -x+10

The angle of elevation to a nearby tree from a point on the ground is measured to be 66^{\circ} ∘ . How tall is the tree if the point on the ground is 68 feet from the tree? Round your answer to the nearest tenth of a foot if necessary.

Answers

By comparing with a right triangle, we will see that the height of the tree is 62.12ft

How tall is the tree?

We can compare the situation with a right triangle. Such that the hypotenuse measures 68 ft, and an angle measures 66°.

We want to get the height of the tree, which would be the opposite cathetus, then we can use the relation:

Sin(a) = (opposite cathetus)/hypotenuse.

Sin(66°) = H/68ft

Tan(66°)*68ft = H = 62.12ft

The height of the tree is 62.12ft

Let's first look only at the numerator: 5x^2 - 5

Consider this question: What do both terms have in common?

The answer is 5, both terms contain a 5, so we can factor it out.

5(x^2 - 1)

Now let's look at the denominator, considering the same question: 3x^2 + 3x

This time, both terms contain a 3 and an x.

3x(x^2 + 1)

Now we are here: [ 5(x^2 - 1) ] / [ 3x(x + 1) ]

In the numerator, the binomial factors out into (x + 1)(x - 1). There is also an (x + 1) in the denominator, so those to binomials cancel out. That leaves us with the following expression:

5(x - 1) / 3x

Answer:

-y = x-1 is a fairly simple equation at least with real integers.

I hope to help you understand the process of solving it so you can apply the thinking to increasingly difficult equations. If this equation is difficult for you, I will try to explain it simply.

let's try a simple trick. If you want to solve for y, then it's helpful to remove the negative from it.

that means you need to do the same thing to the x side, but since x is already positive it needs to change to -x to balance things out.

the equation now reads y = -x+1 because we have reversed the negative and positive values on both sides of the equation.

I hope this helps simplify the thinking behind solving an equation of this nature. The two previous answers above this one are both correct, but may be just a tad more complex than you need at this moment.

We first solve everything in the parenthesis. So: (7 -5) = 2 and (20 - 19) = 1. Now we change the equation:

3[(2)2 +(1)2] + 14

Then we multiply inside the brackets: 2 x 2 = 4 and 1 x 2 = 2. So the equation now looks like this:

3[ 4 + 2] + 14

Now we add:

3{6} + 14:

Measure of dispersion

Mean is the ratio of the sum of data to the ample size. Median is the middle number after rearrangement while the mode is the most occurring number.

Given the sequence of numbers in order of size as 5, _, _, _, _ 24

Since 2 number falls in the middle and the median is 14, hence:

x +y/2 = 14

Since 8 is the mode, we can assume x = 8 in order to determine "y" as shown

8+y/2 = 14
8+y = 28
y = 16

The sequence of numbers will become 5, 8, 8, 16, _ 24 (8 was repeated twice being the mode)

The last unknown number can then be any value between 16 and 24. Using 22 as the last unknown value, the remaining four cards that could be on the card are 8, 8, 16 and 22

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the percentage be represented as A

Now , the equation will be

The time be represented as p = 45 minutes

The value of p = 3/4 hours

The value of q = 3 hours

So , the percentage is A = ( p/q ) x 100

Substituting the values in the equation , we get

The percentage A = ( 3/4 ) / 3 x 100

On simplifying the equation , we get

The percentage A = ( 3/12 ) x 100

The percentage A = ( 1/4 ) x 100

The percentage A = 25 %

Hence , the percentage is 25 %
