"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.

The requied solution are (f+g)(x) = 10x² + 10 - 5x and (f-g)(x) = 10x² + 6 + 5x.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The functions are given in the question, as follows:

f(x) = 10x² + 8 and g(x) = 2 - 5x

To find (f+g)(x) we add f(x) and g(x) term by term.

(f+g)(x) = f(x) + g(x)

Substitute the values of given functions, and we get

(f+g)(x) = 10x² + 8 + (2 - 5x)

(f+g)(x) = 10x² + 10 - 5x

To find (f-g)(x) we subtract g(x) from f(x) term by term.

(f-g)(x) = f(x) + g(x)

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.

Step-by-step explanation:

The range of the f(x) is {- 4, 0, 4, 8, 12}

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}

The range of the f(x) can be calculated as follows

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

Therefore,

The range of the f(x) is {- 4, 0, 4, 8, 12}

The speed of the current is  7 miles per hour,

and the speed of the boat in still water is  2 miles per hour.

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

y = 2 miles per hour

speed of the boat is 7 miles per hour and the speed of the current is 2 miles per hour.

Hence boat's speed is  7 miles per hour and the current speed is 2 miles per hour.

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,

The height of the hat is 9.0 inches.

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

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
39/13 = 3

The area of the square is given by:

A = x^2 - 16x + 64

Remember that the area of a square of side length S is given by the formula:

A = S^2

Here we know that the side length is x - 8, then we can just replace that on the formula above to get:

A = (x - 8)^2

Now we can expand that:

A = (x - 8)^2 = (x - 8)*(x - 8)

A = x^2 - 16x + 64

That is the area.
