15h - 4 = 6
Two step problem

Answers

Answer 1

Answer:

h = 10/15

Step-by-step explanation:

Isolate the variable, h. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 4 to both sides of the equation:

15h - 4 (+4) = 6 (+4)

15h = 6 + 4

15h = 10

Next, divide 15 from both sides of the equation:

(15h)/15 = (10)/15

h = 10/15 or 0.667 (rounded)

Solve the trigonometric equation for all values: -7 < or equal to x < 7 Question: Cot 1/2x-1=0

Answers

Answer:

x =90

Step-by-step explanation:

Cot 1/2x-1=0

Add 1 to both sides

Cot 1/2x = 0+1

Cot 1/2x = 1

1/tan1/2x = 1

Tan 1/2x = 1

1/2x = arctan1

1/2x =45

x = 45×2

x = 90

Hence the value of x is 90

Which is a zero of the function f(x) = 2x – 6?
2

-3

-6

3

Answers

The answer is 3 because it is

Answer and explanation:

The answer is actually -3. We already know f(x)/y is equal to 0, so the equation is then simplified to 0 = 2x - 6. You do inverse operation, so then -6 = 2x. Then -6 divided by 2 is -3. So -3 = x. Therefore, the zero of the function f(x) = 2x – 6 is -3.

A farmer has a field in the shape of a semicircle of diameter 50 m. First,
calculate the length of the semicircle to 1 decimal place.
50 m

Answers

Answer:

157.1 m

Step-by-step explanation:

Here, we want to calculate the length of the semi-circle

This simply refers to the circumference of the semi-circle

Mathematically, the circumference is half that of a full circle

The circumference of a full circle is;

C = pi * d

For half circle or semi-circle;

It is ;

C = (pi * d)/2

D = 50 m

The circumference is thus;

C = 50 * 3.142

C = 157.1 m

A cell is enclosed by a plasma membrane, which forms a selective barrier that allows nutrients to enter and waste products to leave. The interior of the cell is organized into many specialized compartments, or organelles, each surrounded by a separate membrane. One major organelle, the nucleus, contains the genetic information necessary for cell growth and reproduction. Each cell contains only one nucleus, whereas other types of organelles are present in multiple copies in the cellular contents, or cytoplasm. Organelles include mitochondria, which are responsible for the energy transactions necessary for cell survival; lysosomes, which digest unwanted materials within the cell; and the endoplasmic reticulum and the Golgi apparatus, which play important roles in the internal organization of the cell by synthesizing selected molecules and then processing, sorting, and directing them to their proper locations. In addition, plant cells contain chloroplasts, which are responsible for photosynthesis, whereby the energy of sunlight is used to convert molecules of carbon dioxide (CO2) and water (H2O) into carbohydrates. Between all these organelles is the space in the cytoplasm called the cytosol.From http://www.britannica.com/EBchecked/topic/101396/cell)Cell Description #2Under the microscope, a cell looks a lot like a fried egg: It has a white (the cytoplasm) that's full of water and proteins to keep it fed, and a yolk (the nucleus) that holds all the genetic information that makes you you. The cytoplasm buzzes like a New York City street. It's crammed full of molecules and vessels endlessly shuttling enzymes and sugars from one part of the cell to another, pumping water, nutrients, and oxygen in and out of the cell. All the while, little cytoplasmic factories work 24/7, cranking out sugars, fats, proteins, and energy to keep the whole thing running and feed the nucleusthe brains of the operation. Inside every nucleus within each cell in your body, there's an identical copy of your entire genome. That genome tells cells when to grow and divide and makes sure they do their jobs, whether that's controlling your heartbeat or helping your brain understand the words on this page.From The Immortal Life of Henrietta Lacks, p. 3Thats the story posting the questions for it right now During the Gilded Age, technological innovations led to greater wealth and more leisure time, resulting in 25.
