33,300 is standard form of the given question .
What does basic math standard form mean?
Writing down extremely large or extremely small numbers simply is possible using standard form. 103 = 1000, so 4 × 103 = 4000 . Therefore, 4000 can be expressed as 4 103. Even bigger numbers can be easily recorded in standard form using this method. The conventional form of small numbers is also an option.Definition of Standard Form?
A standard form is a way of expressing a certain mathematical idea, such as an equation, number, or expression, in a way that adheres to a set of norms. The standard form is used to concisely represent very big or very small values. For instance, 4,500,000,000 years is how 4.5 billion years is written.Thirteen million, three hundred = 33,300
Two thousand, six hundred and forty = 2640

Answer:
y = -800x + 294000
286,000
Step-by-step explanation:
To write the equation, you need the slope and the y-intercept.
The slope is -800
You find the slope by the change in y over the change in x
[tex]\frac{288400 - 294000}{7 - 0}[/tex] = [tex]\frac{15600}{7}[/tex] = -800
Now we will find the y -intercept. I will use the slope and the point (0, 294,000) to find this. I could have used the other point given. They will both work.
slope (m) = -800
x = 0
y = 294000
y = mx + b
294000 = -800(0) = b
294000 = b
The equation is
y = mx + b
y = -800x + 294000
2014
y = -800x + 294000
y = -800(10) + 294000
y =-8000 + 294000
y = 286,000

three numbers have a sum of 180. the second number is 4 times the smallest number. the third number is 7 times the smallest number. what is the largest number?
Answer:
105
Step-by-step explanation:
Let x, y and z be the 3 numbers in the order first, second and third
x + y + z = 180
Second number y is 3 times the smallest number and third number z is 7 times the smallest number. So smallest number has to be x
so y = 4x
z = 7x
x + y + z = x + 4x + 7x = 180
12x = 180
x = 15
Largest number = 7 x 15 = 105

Length of Hypotenuse (c) Length of Other Leg (a) Did I Get Them Right?! ( Nope. Keep trying Reset
Looking at the triangle, the reference angle is 30 degrees. The hypotenuse of the triangle is c. The opposite side of the triangle is 7 and the adjacent side is a.
We would determine the hypotenuse, c by applying the sine trigonometric ratio which is expressed as
Sin# = opposite side/hypotenuse
Sin 30 = 7/c
cSin30 = 7
c = 7/Sin 30 = 7/0.5
c = 14
We would determine the adjacent side, a by applying the tangent trigonometric ratio which is expressed as
Tan# = opposite side/adjacent side
Tan 30 = 7/a
aTan30 = 7
a = 7/Tan 30 = 7/0.5774

which statement is true?
A. The output value of the function is 4 when the input value is -2
B. The output value of the function is 7 when the input value is 1
C. The output value of the function is 6 when the input value is x
D. The output value of the function is 8 when the input value is -2
The statement which is true is Option(D) The output value of the function is 8 when the input value is -2.
What do mathematical functions mean?An expression, rule, or regulation that establishes a relationship between one variable (the independent variable) and another variable (the dependent variable) is referred to as a function in mathematics.
Given function:
H(x) = -x + 6
In Option A, the input value is -2 so the output of the function will be,
H(x) = -x + 6 = -(-2) +6 = 2+ 6 = 8 ,which is not equal to the given output value 4.
Hence, the statement is false.
Similarly in Option B and C, the input values are 1 and x.
H(x) = -x + 6 = -1 +6 = 5 ≠ 7
H(x) = -x + 6 ≠ 6
The given output values are not equal to the output values calculated.
So both statements are false.
In Option D the input value is -2 and the output value is 8 which is a correct statement as calculated in Option A.

The mass of a human cell In scientific notation is 1X 10^10 kg.
What is Scientific notation?
Scientific notation is a means to express values that are either too big or too little to be conveniently stated in decimal form (typically would lead to a long string of digits). It is also known as the standard form in the UK and scientific form, standard index form, and standard form. Scientists, mathematicians, and especially engineers frequently utilize this base ten notation because it can make some mathematical operations simpler.In many professions, huge numbers are typically expressed using the normalized scientific form, unless an alternative normalization method, such as engineering notation, is preferred.Given that mass of a human cell= is 0.000000000001 kg

A demand function for a certain product is given by the equation q = 1200 - 5p, where p is the price in
dollars, and q is the quantity demanded. Find a function to represent the revenue generated by producing
and selling q items. Use this function to determine the quantity that maximizes revenue. What price
should be charged in order to maximize revenue?
A function to represent the relation is f = q × p, the quantity that maximizes value could only be when q = p, therefore p = 200 so, q = 200 too according to demand function q = 1200 - 5p.
What is demand function?In mathematics, the relationship between demand and its factors is represented by a demand function. The function demonstrates how elements like a product's own price, buyer income, and the cost of related products affect demand for a given good (substitutes and complements).
We can deduce from the equation how they influence a product's demand, whether positively or negatively, and how much.
A function for generated revenue is simply f = q × p
where f is the generated revenue and
q is the quantity and
p is the price.
The quantity that maximizes value could only be when q = p
Lets substitute the value of q in q = 1200 - 5p,
q + 5p = 1200
But q = p so
p + 5p = 1200
6p = 1200
p = 1200/6
p = 200
So when price is 200 the revenue will be maximized as the quantity is equal to as price.

The experimental probability of rolling such that the number is more than 3 is 0.44.
The proportion of outcomes where a specific event occurs in all trials, not in a hypothetical sample space but in a real experiment, is known as the empirical probability, relative frequency, or experimental probability of an event.
When a dies is rolled 200 times, the results are:
Frequency Outcome

Therefore,
The experimental probability that a number is more than 3 after rolling will be:
= The sum of outcome above 3 / total outcome
= ( 20 + 30 + 38 ) / ( 32 + 36 + 44 + 20 + 30 + 38 )

Dina pours 16-ounce containers juice into a dispenser with a capacity of 960 ounces. The function y = 16x modeled this situation. What is the range of the function ?
The range of the function, y = 16x, is 60, where y is 960.
What is the range of a function?The range of the function, y = 16x, are the possible values that x can assume to meet the value of y.
Usually, the range of a function is the output value.
Since the value of y = 960, the range of the function will be 60 (960/16).
The capacity of the dispenser = 960 ounces
The capacity of the juice containers = 16 ounces
The function that models the situation is y = 16x
Where y = 960
x = 60 (960/16)
Thus, the implication is that the range of the function or the number of 16-ounce containers that can fill the dispenser with a capacity of 960 ounces is 60.
