The equivalent radical expression for the exponential expression [tex]18^{1/2}[/tex] will be √18.

The positive number, when multiplied by itself, represents the square of the number.

Under the root of any number gives a number by which if we multiply by the same number then it will give us the same number.

For example √4 =2

If we multiply 2×2 then it gives us 4.

√x is also written as [tex]x^{1/2}[/tex]

So,

[tex]18^{1/2}[/tex]  ≡  √18 o will be the correct term in the radical expression.

The product of polynomial [tex](-2m^3+3m^2-m)(4m^2+m-5)[/tex] is [tex]\mathbf{-8m^5+10m^4+9m^3-16m^2+5m}[/tex]

Step-by-step explanation:

We need to find the standard form of polynomial that represents the product of [tex](-2m^3+3m^2-m)(4m^2+m-5)[/tex]

Finding the product of polynomial

[tex](-2m^3+3m^2-m)(4m^2+m-5)\\=-2m^3(4m^2+m-5)+3m^2(4m^2+m-5)-m(4m^2+m-5)\\=-8m^5-2m^4+10m^3+12m^4+3m^3-15m^2-4m^3-m^2+5m\\Combining\:like\:terms\\=-8m^5-2m^4+12m^4+10m^3+3m^3-4m^3-15m^2-m^2+5m\\=-8m^5+10m^4+9m^3-16m^2+5m\\[/tex]

f(m) = 5 + 0.5m is the algebraic expression that models the cost of taxi ride.

Here, we are given that the cost of taxi ride is 5 dollars plus 50 cents per mile.

This means that-

the fixed cost = $5

variable cost = 50 cents per mile = $0.5 per mile

Let the number of miles travelled be m

then the variable cost will be = $0.5m

The total cost is given as-

total cost = fixed cost + variable cost

total cost = 5 + 0.5m

⇒ f(m) = 5 + 0.5m

here, m = miles travelled

and f(m) = total cost of the taxi ride

Hence, f(m) = 5 + 0.5m is the algebraic expression that models the cost of taxi ride.

Answer:

The domain of the graph is all real numbers.

Step-by-step explanation:

The equation that is set for this problem is y = |x+2| − 4. When finding the domain and range of this function, the domain and range is:

Domain: (−∞,∞), {x|x∈ℝ}  ⇒ (The domain (x-values) is all real numbers

Range: [−4,∞), {y|y≥−4}  ⇒  (The range (y-values) need to be greater than or equal to −4)

So, according to this information and we look at the statements, out of the four, the correct option is “the domain of the graph is all real numbers”.

The number of calculations that a computer can perform in 10 seconds is 1050.

The exponential form of 1050 is 1.05 × 10³

Given,

The number of calculations that a computer can perform per second = 105

We have to find the number of calculations can it perform in 10 seconds.

That is,

Number calculations in 10 seconds = Number of calculations per second × 10

Number of calculations in 10 seconds = 105 × 10

Number of calculations in 10 seconds = 1050

That is, the number of calculations that a computer can perform in 10 seconds is 1050.

Answer:

Richard got a 90% score on his quiz! Therefore, he got 10% of the questions incorrect.

Step-by-step explanation:

The method I used to find this answer was simply taking the amount he had gotten, 36, and dividing it by the initial amount of questions- 40. From there, I got 0.9, which is the equivalent of 90%. 100% minus 90% is 10%, so he got 10% incorrect. Sorry for the mishap, I didn't pick up that it was meant to be the amount incorrect. :)

Answer:

100 divide by 40 you get 2.5 multiply by 4 you should get 10 percent

Answer:

None of the option match the answer

Step-by-step explanation:

6x° = (2x + 3)° + 77° (Exterior angle of a triangle = sum of two interior angle )

6x = 2x + 3 +77

subtract 2x from both sides

6x - 2x = 2x - 2x + 3 + 77

4x = 3 + 77

4x = 80

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Total number of members in the relay team = 3 members

Total distance covered by the 3 members of the relay team = 3/8 miles

Now the equation will be ,

The distance ran by each member of the team =
Total distance covered by the 3 members of the relay team / Total number of members in the relay team

So , The distance ran by each member of the team = ( 3/8 ) / 3

                                                                                     = 3/8 x 1/3

                                                                                     = 1/8 miles

Therefore ,  the distance ran by each member of the team is 1/8 miles

And , taking the sum of each person's distance , we get

1/8 + 1/8 + 1/8 = 3/8

which is the total distance covered by the 3 members

Hence , The distance ran by each person in the relay team is 1/8 miles

Step-by-step explanation:

The volume of a box in cubic inches = 13,824 cubic inches

The volume of a box in cubic feet = 8 cubic feet

The volume of a box = (length)(width)(height).

Give the following:

Length of the box = 8 feet

Width of the box = 4 feet

Height of the box = 3 inches

Convert the length and width to inches (1 foot = 12 inches)

Length of the box = 8 feet = (8)(12) = 96 inches

Width of the box = 4 feet = (4)(12) = 48 inches

Height of the box = 3 inches = 3/12 = 0.25 ft

The volume of a box in cubic inches = (96)(48)(3) = 13,824 cubic inches

The volume of a box in cubic feet = (8)(4)(0.25) = 8 cubic feet

Given the line

[tex]y=-x+2[/tex]

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

here

m is the slope and b is the intercept

Thus, the slope = -1

We know that the parallel lines have the same. Thus, the slope of the parallel line is: -1

Using point-slope of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = -1 and the point (4, 0)

[tex]y-0 = -1 (x-4)[/tex]

Writing in the slope-intercept form

[tex]y = -x+4[/tex]

Thus, the slope-intercept form of the equation of the line equation parallel to y=-x+ 2 will be:

ine is: y = -x-1

Given the assumed line

y = -x-1

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

here

m is the slope and b is the intercept

Thus, the slope = m = -1

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = -1

perpendicular slope = – 1/m = -1/-1 = 1

Using point-slope of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 1 and the point (4, 3)

[tex]y - 3 = 1 (x-4)[/tex]

Writing in the slope-intercept form

y-3 = x-4

y = x-4+3

Step-by-step explanation:

The two equations to set up to solve |2x−3|=11 are 2x − 3 = 11 and 2x − 3 = -11

Hence, option C)2x − 3 = 11 and 2x − 3 = -11 is the correct answer.

Given the equation in the question;

| 2x − 3 | = 11

To solve the equation, we have to remove the absolute value term and this will create the a ± on the right side of the equation.

Note that; |x| = ±x

Hence;

| 2x − 3 | = 11

2x − 3 = ±11

The solution of the equation is the result of both the positive and negative portions of the of the solution.

2x − 3 = 11 and 2x − 3 = -11

Therefore, the two equations to set up to solve |2x−3|=11 are 2x − 3 = 11 and 2x − 3 = -11

Hence, option C)2x − 3 = 11 and 2x − 3 = -11 is the correct answer.
