which of the following options correctly describe scientific notation? select all that apply. multiple select question. one digit is present to the right of the decimal point in all cases. the exponent can be a positive or negative integer. the number must be a positive integer. one digit is present to the left of the decimal point in all cases.
"At least one digit is present to the left of the decimal point in all cases" and "the exponent can be a positive or negative integer" are the correct option for the given question.
Decimal numbers, also known as base-10 numbers. They use a system of digits from 0 to 9 and a decimal point to represent values. The decimal point separates the integer part of the number from the fractional part.
For example, in the decimal number 56.36, 56 is the integer part and 36 is the fractional part.
Hence, at least one digit is present to the left of the decimal point in all cases.
In scientific notation, the exponent is used to represent very large or very small numbers. The number is written in the form of a x [tex]10^n[/tex] where 'a' is a decimal number between 1 and 10 (inclusive) and 'n' is an integer (positive or negative) exponent.
Say, for example, 0.00006 can be written as 6 x [tex]10^{-5}[/tex] where 6 is the coefficient and -5 is the exponent.

Sally is 54 years old and her mother is 80, how many years ago was Sally’s mother times her age?
Answer: 41 years ago, when Sally was 13 and her mother was 39.
Answer: 41 years
Step-by-step explanation:
I reckon the question is asking when her mother was 3 times her age.
S = 54
M = 80
54 - 41 = 13
80 - 41 = 39

A party hat is in the shape of a cone with dimensions shown.
Find the height of the hat. Round to the nearest tenth.
4.3 in.
10 in.
The height of the hat is 9.0 inches.
How to find the height of a cone?A party hat is in the shape of a cone with dimensions shown . Therefore, the height of the cone can be found as follows:
The radius of the cone is 4.3 inches and the slanted height of the cone is 10 inches.
Therefore, Pythagoras's theorem can be used to find the height of the cone. The radius and the slanted height of the cone forms a right angle triangle.
Therefore,
10² - 4.3² = h²
h² = 100 - 18.49
h² = 81.51
square both sides
h = √81.51
h = 9.02828887442
h = 9.0 inches
Therefore,
height of the hat = 9.0 inches

The probability of successful region is =241/2500 Option b is correct.
Since √x=12, 12 ≤√x<13 and thus 144 ≤ x < 169.
The successful region is when 120 ≤ 10√x < 121 in which case 12 ≤√x< 12.1
Thus, the successful region is when

The successful region consists of a 2.41 long segment, while the total possibilities region is 25 wide. Thus, the probability is

cara is ordering mushrooms for her restaurant. the graph shows the cost, y, of ordering x pounds of mushrooms what is the equation of the line what is the cost of ordering 6 pounds of mushrooms? iready quiz derive linear equations
Answer: Based on the information provided, it appears that the graph represents a linear equation, which is a straight line. The equation of a straight line can be represented in the form y = mx + b, where m is the slope of the line and b is the y-intercept.
To find the equation of the line, we need two points on the line. We can use the points (x1, y1) and (x2, y2) to calculate the slope of the line, m, using the formula:
m = (y2 - y1) / (x2 - x1)
Without knowing the coordinates of the points on the graph it is not possible to give the equation of the line.
To find the cost of ordering 6 pounds of mushrooms, we would substitute 6 for x in the equation of the line and solve for y.
y = mx + b
y = m(6) + b
Without the equation of the line, it's not possible to find the cost of ordering 6 pounds of mushrooms.

For the given condition number of laps "l" is the independent variable.
What are Variables?A symbol (often a letter) is used in mathematics to represent an unknowable numerical value in an equation or algebraic statement. A variable can be defined as a quantity that is changeable and not fixed. Variables are crucial since they make up a significant portion of algebra.
Given The amount of time, t, to finish a race and the number of laps, I,
there are two types of variables,
dependent and independent variables,
In an algebraic equation, an independent variable is one whose values are not impacted by changes. When there are two variables in an algebraic equation, x and y, and each value of x depends on every other value of y, x is an independent variable, and y is a dependent variable.
for the given condition,
the time taken to finish the race directly varies with the number of laps,
so time is dependent on the number of laps and a number of laps "l" is the independent variable.
Hence the independent variable is the number of laps, "l".

Range of the function:A collection of numbers that represent every possible value of x is said to be the function's domain. The set of numbers that a function can produce is known as its range.
To find the range of a function substitute the domine values into the given function f(x).
Here we have
Give domain of f(x) = 4x + 4; { -2, -1, 0, 1, 2}

Take x = -2 => f(x) = 4(-2) + 4 = -8 + 4 = - 4
Take x = -1 => f(x) = 4(-1) + 4 = - 4 + 4 = 0
Take x = 0 => f(x) = 4(0) + 4 = 0 + 4 = 4
Take x = 1 => f(x) = 4(1) + 4 = 4 + 4 = 8
Take x = 2 => f(x) = 4(2) + 4 = 8 + 4 = 12

The speed of the current is 7 miles per hour,

What is speed?The distance that an object travels in relation to the amount of time it takes to do so can be used to define speed. In other terms, it is a measurement of an object's motion's speed without direction Velocities are what we get when speed and direction are combined.
Given A boat travels 10 miles upstream in 2 hours. Going downstream, it can travel 18 miles in the same amount of time.
let the speed of the boat and current be x and y,
for downstream,
x + y = D₁/t₁
D₁ = distance traveled in downstream = 18 miles
t₁ = time taken = 2 hours
x + y = 18/2
x + y = 9 .........(1)
for upstream,
x - y = D₂/t₂
D₂ = distance traveled in upstream = 10 miles
t₂ = t₁ = time taken = 2 hours
x - y = 10/2
x - y = 5 .......(2)
adding both equations
x + y + x - y = 9 + 5
2x = 14
x = 7 miles per hour
and x + y = 9
7 + y = 9
y = 9 - 7

of course, quadratic equations don't always come with the coefficients labeled , , and . for example, assuming the solutions are real and , the larger solution of -bx^2 c^2x a^3
The equation -bx2 + c2x + a3 has a larger solution of x = (-c + sqrt(c2 - 4ab))/2a.
We must first move the constants to the right side of the equation in order to find the solution to the equation
-bx2 + c2x + a3 = 0.
As a result, we have the equation -bx2 + c2x = -a3. The result is x2 - (c2/b)x = -a3/b after dividing both sides by -b. The quadratic formula can be used to resolve this quadratic equation. x = (-c + sqrt(c2 - 4ab))/2a is the equation's more complex solution. We enter the coefficient values into the quadratic formula to verify this. The broader solution is
x = (-4 + sqrt(4 - 24))/4 = (-4 + sqrt(-20))/4 = (-4 + 25)/4 = 0.55 - 1,
