The values of a, b, h, and k, given the equation below;

Given

An ellipse has vertices along the major axis at (0, 8) and (0, –2).

The foci of the ellipse are located at (0, 7) and (0, –1).

It can be seen that the major axis is parallel to the y axis.

The major axis points are;

(h, k +a) = (0, 8)

(h, k -a) = (0, -2)

Here, k + a = 8

k - a = -2

Subtracting the equations;

k + a - k + a = 8 + 2

2a = 10

a = 10/2 = 5

The foci are;

(h, k +c) = (0, 7)

(h, k -c) = (0, -1)

Here, k + c = 7

k - c = -1

Subtracting the equations;

k + c -k + c = 7+ 1

2c = 8

c = 8/2 = 4

The foci are given by;

[tex]\rm c^2=a^2-b^2\\\\b=\sqrt{a^2-c^2} \\\\b = \sqrt{5^2-4^2}\\\\b = \sqrt{25-16} \\\\ b =\sqrt{9}\\\\ b=3[/tex]

The equation is;

[tex]\rm \dfrac{(x-h)^2}{b^2}+\dfrac{(x-k)^2}{a^2}=1\\\\ \dfrac{(x-0)^2}{3^2}+ \dfrac{(x-3)^2}{5^2}=1[/tex]

Answer:

D. 1 has a lower absolute value

Step-by-step explanation:

D is the answer because -4 is negative and can never be more than a positive number like 1.

Answer:

D

Step-by-step explanation:

because 1 have 1 absolute value and -4 have 4 absolute value

since 4 is greater than 1

so 1 have lower absolute value

Step-by-step explanation:

The 2 base angles of an isosceles triangle are congruent.

66° + 66° + 48° = 180° ( sum of angles in a triangle )

Thus the triangle is isosceles with base angles = 66° and vertex = 48°

Answer:

x= 1

Step-by-step explanation:

The value of y = -5x

Plug it in the equation of y + 4x = -1

So it becomes, -5x + 4x = -1

Combine like terms which are -5x and 4x which equals to -x

Eliminate the negative sign because x cannot be negative. Apply that to -1. It becomes 1.

Hope you find this helpful!

Answer:

Step-by-step explanation:

Equation 1: y = -5x

Equation 2: y + 4x = -1

Step 1. Substitute y in equation 2 using equation 1

You would get, -5x + 4x = -1

Step 2. Combine like terms

-x = -1

Step 3. Cross out the negatives

x = 1

Step 4. Substitute x in Equation 1 to get y

y = -5(1)

y = -5

Answer:

  a. length: 20-2x; width: 12-2x; height: x

  b. V = 4x^3 -64x^2 +240x

  c. cubic trinomial

  d. 262.7 cubic inches maximum for a 2.4 inch square

  e. 15 × 7 × 2.5 inches for 262.5 in³ volume

Step-by-step explanation:

If the square cut from each corner has side length x, the dimensions are ...

__

The volume is the product of length, width, and height.

  V = LWH

  V = (20 -2x)(12-2x)(x) = 4(x-10)(x-6)x = 4(x^2 -16x +60)x

  V = 4x^3 -64x^2 +240x

__

The volume function is a cubic trinomial.

__

The maximum volume will be found where the derivative of the volume function is zero.

  V' = 12x^2 -128x +240 = 0

  x^2 -32/3x +20 = 0 . . . . divide by 12

  (x -16/3)^2 = 76/9 . . . . . complete the square

  x = (16 -√76)/3 ≈ 2.4 . . . . size of the square

  V = 4(2.4)(10 -2.4)(6 -2.4) ≈ 262.7 . . . cubic inches

The maximum box volume is about 262.7 cubic inches when the square is about 2.4 inches on each side.

__

A graphing calculator shows there to be two solutions for a volume of 262.5 cubic inches. The rational solution is x = 2.5 inches. The box dimensions would be ...

Hi there!!

  If you need  X to be solved then the answer is X=Y over 5+3 and if your looking for the answer for Y then the answer is Y=5x−15

When you are solving for X you will need to use the distributive property so you can multiply 5 by X-3.

Y=5x-15. Once you've done that then you need to swap sides so all of the variables are on the same side as each other  (they need to be on the left side) 5x-15=Y.

Then you need to add 15 to both of the sides to make it look like this     ->5x=Y+15

When that's done you then need to divide both sides by 5 so it then looks like this when done.

5x over 5= Y+15 over 5

When you divide this by 5, it then undoes the multiplication by 5.

X= Y+15 over 5

Finally, you need to divide Y+15 by 5

X=Y over 5 plus 3

When solving for Y, all you will need to do is use the distributive property to multiply 5 by X-3.

Answer:

Step-by-step explanation:

The total amount is $2.41.

If the are 23 pennies, then the amount excluding the pennies is:

This amount comprises quarters, nickels and dimes.

Each of them is multiple of 5:

Any amount made by the combinations of these has to be multiple of 5 cents. But the sum is $2.18, which is not multiple of 5 cents.

It means Henry can't make it.

Answer:

1a) A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound.

1b)An ionic compound formed by acid-base reactions and without those ions is called a salt. Water is definitely one of the most important inorganic compounds to all living things. It is a compound comprised of two hydrogen atoms and one oxygen atom.

The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

2a)Regulates body temperature. Moistens tissues in the eyes, nose and mouth. Protects body organs and tissues. Carries nutrients and oxygen to cells.

2b)If a cell is seriously deprived of water,

this lack of water would most likely affect

the cell's enzymes because:

• The cytoplasm and plasma

membrane would not function

properly

Both the plant and animal cell needs

water in order to perform their basic

functions which include transport of

materials, waste distribution, production

of genetic information, and many more.

As a result of this, we can see that there

would be a serious problem if any

of these cells are deprived of water

which would lead to the cytoplasm and

plasma membrane to partially shut

down because they would not be able to

engage in protein synthesis and other

important functions.

3a)Carbohydrates provides energy rich for organic compounds made of elements carbon, hydrogen and oxygen. The lipids contain the element nitrogen. The carbohydrates contain the only elements carbon, hydrogen, and oxygen.

3b)Organic nitrogen occurs in many forms, including amino acids, proteins, nucleic acids, nucleotides, and urea.

3c)A carbohydrate has only Carbon, Hydrogen and Oxygen, with the hydrogen and oxygen in the ratio 2:1. A protein is made of amino acids. ... So without nitrogen atoms the compound can not be a protein.

Permutation and Combination form the principles of counting and they are applied in various situations.

A permutation is a count of the different arrangements which can be made from the given set of things. In permutation the details matter, as the order or sequence is important.

Here given that,

A blood bank needs 5 people to help with a blood drive. 10 people have volunteered.

Here, We get;

The different groups of 5 can be formed from the 10 volunteers is,

⇒ ¹⁰C₅

⇒ 10! /5! 5!

⇒ 10×9×8×7×6 / 5×4×3×2

⇒ 252

Thus, The different groups of 5 can be formed from the 10 volunteers is,

⇒ 252
