-8x^2- [8x - 6x^2 - 8x)] - [7 + (-8x - 7)]

Answer: Approximately 3799 or 3800 cubic inches

Step-by-step explanation:

To find the volume of a cylinder I imagine I'm first finding the area of one of the circular "bases" (top or bottom) using the formula: Area = pi x radius squared. Once you have the area of a base, imagine you "stack" as many of them on top of each other until you get to the given height (here, it's 10 in. tall).

So . . . pi (3.14) x 11 (radius)^2 (3.14 x 11 squared) = 3.14 x 121 = 379.94 x 10 in. tall = 3799.4 cubic inches (in^3)

g(x) =f(x) +3

given f(x) =3x

i.e. g(x) =3x+3

For F(x) to be same as g(x)

3 must be added to f(x)

i.e. h(x) =3x+3

->h(x)= 3x +3(1)

-> h(x) = f(x) +f(1)

-> h(x) =f(x+1)

Hence Option (a) is your answer...

Hope it helps...

Answer:

A) h(x) =  f(x +1).

Step-by-step explanation:

Given : f(x) = 3x and g(x) = 3x + 3.

To find : Which transformation of f(x) will produce the same graph as g(x).

Solution : We have given

f(x) = 3x

For x = 1.

f(1) = 3 (1)

f(x) = 3.

Plug the value of f(x) =3x and f(1) = 3 in g(x).

g(x) = 3x + 3.

g(x) = f(x) + f(1).

We can write  f(x) + f(1) = f(x +1).

g(x) = f(x +1)

h(x) = f(x +1)

So, it is a new function produce the same graph as g(x).

h(x) =  f(x +1).

Therefore, A) h(x) =  f(x +1).

I think the answer is n-20- first choice.

ANSWER

n-20

EXPLANATION

The terms of the sequence are:

-19,-18,-17,-16,-15,...

The first term of the sequence is

a=-19 and the common difference is d=-18--19=1

The rule is given by:

f(n)=a+d(n-1)

f(n)=-19+1(n-1)

f(n)=-19+n-1

f(n)=n-20.

Therefore the rule for the given sequence is n-20.

C, Plus or minus 3

Step-by-step explanation:

to solve 3x² - 27 = 0, we want to get the x by itself, so lets add 27 to both sides.

3x² = 27 < divide both sides by 3 to get x alone

3x²/2 =x²

27/3 = 9

x² = 9 < we can use the square-root property and square both sides of the equation to get x alone. we use the ± because there are 2 possible solutions to a square rooted number

√x² = x

√9 = 3

x = ±3

ANSWER

[tex] \sqrt{5} [/tex]

EXPLANATION

The given points are (1,0) and (0,2).

We use the distance formula:

[tex]d = \sqrt{(x_2-x_1)^2 +(y_2-y_1)^2} [/tex]

We substitute the given points into the formula to get:

[tex]d = \sqrt{(0-1)^2 +(2-0)^2} [/tex]

We simplify to get:

[tex]d = \sqrt{1+4} [/tex]

[tex]d = \sqrt{5} [/tex]

Therefore the distance between the two points is √5 units.

since height to base ratio is tan73 so approx ratio is 3.27

The approximate height-to-base ratio is 3.27: 1

Given,

A 20-foot ladder is set up against a building so that the ladder makes an angle of 73° with the ground.

The height, h, is the vertical distance from the top of the ladder to the base of the building.

The base, b, is the horizontal distance from the bottom of the ladder to the base of the building.

We need to find what is the approximate height-to-base ratio.

Sin Ф = Perpendicular / Hypotenuse

Cos Ф = Base / Hypotenuse

Tan Ф = Perpendicular / Base

Find the height in the figure.

Sin 73 = h / 20 ft

Sin 73 = 0.9563

So,

0.9563 = h / 20 ft

h = 0.9563 x 20 ft

h = 19.126 ft

Find the base in the figure.

Cos 73 = b / 20 ft

Cos 73 = 0.2924

0.2924 = b / 20 ft

b = 0.2924 x 20 ft

b = 5.848 ft

Find the approximate height-to-base ratio.

= h : b

= 19.126 : 5.848

= 3.27 : 1

Thus the approximate height-to-base ratio is 3.27: 1

Answer:

The 3rd choice: 2/3 tank - 1/6 tank = 1/2 tank

Step-by-step explanation:

I assume those numbers are fractions.

The gas tank of Wendy’s car was 2/3 full. She used 1/6 of a tank of gas when driving to and from work. Which equation shows how full the gas tank is now?

We subtract 1/6 from 2/3. We need to use the common denominator 6.

2/3 - 1/6 = 4/6 - 1/6 = 3/6

Now we reduce 3/6.

2/3 - 1/6 = 1/2

Answer: 2/3 tank - 1/6 tank = 1/2 tank

The absolute value equation representing the word count for the scholarship essay is |w - 800| <= 50, ensuring that the essay will be between 750 and 850 words long.

To represent the word count requirements for the scholarship essay using an absolute value equation, you can consider the midpoint of the word limit, which is the average between the minimum and maximum word count. This midpoint is at 800 words since (750 + 850) / 2 equals 800. Now, you can state the absolute difference from this midpoint that is allowed on either side of 800, which is 50 words, since 850 - 800 equals 50 and 800 - 750 equals 50. Therefore, the absolute value equation that represents the number of words (w) the scholarship essay should be is |w - 800| <= 50. This equation tells us that the word count can be 50 words fewer or 50 words greater than 800, perfectly capturing the range of 750 to 850 words.

Answer:

b = √c²-a²

Step-by-step explanation:

b² = c² - a²

b = √c²-a²

The Pythagorean theorem, denoted as a² + b² = c², can be rearranged as b = √(c² - a²) to solve for one of the sides of a right triangle. Once the lengths for a and c are known, they can be substituted into the formula to find the length of b.

The Pythagorean theorem, a key geometric principle, can be used to solve for one of the sides in a right triangle given the lengths of the other two. Usually, it's denoted as a² + b² = c², where a and b are the lengths of the triangle's legs, and c is the length of the hypotenuse. In the question, you want to solve for b.

First, let's isolate b in the formula. Rewrite the formula as b² = c² - a². To find the length of b, take the square root of both sides, resulting in b = √(c² - a²).

Now, once you have the values for a and c, you can substitute them into the formula to find b. This application of the Pythagorean theorem can be very useful in various situations where you have a right triangle, and you know the lengths of two of its sides but need to find the length of the third side.

Set B: (-1, -6), (0, 2), (1, 2), (3, 6)

Set C: (2, 1), (4, 2), (2, 3), (8, 4)

Now we need to state about which of the following sets of ordered pairs represent a function.

We know that a function can't have repeated values in domain that is x-value can't repeat.

we see that set C has repeated x-value "2".

Then set C is not a function.

Hence correct choice is:

d. Set A and Set B

Answer:

A and B represent functions.

Step-by-step explanation:

In a function, any input (x-) value may have only one associated y value.  If the same input appears more than once, we know immediately that the data do not represent a function.

A:  The inputs are unique:  {5, 4, 3, 2} so this is a function.

B:   The inputs are unique:  {-1, 0, 1, 3}, so this is a function.

C:   2 is used twice as input, so this is not a function.

Hey there! :)

-7x - 4y = -8

To find the slope, we must turn this equation into slope-intercept form.

Slope-intercept form is : y=mx+b ; where m=slope, b=y-intercept

To get here, we must isolate y by adding 7x to both sides of our original equation.

-7x + 7x - 4y = 7x - 8

Simplify!

-4y = 7x - 8

Then, divide both sides by -4.

-4y ÷ -4y = (7x - 8) ÷ -4y

Simplify!

y = -7/4x + 2

Congrats, we got y isolated! Now, review the slope-intercept form equation to figure out what our slope & y-intercept are.

After reviewing our slope intercept form equation, we can come to the conclusion that -7/4 is our slope because it's in the "m" value slot, and 2 is our y-intercept because it's in the "b" spot.

So, our answer is :

Slope = -7/4

Y-intercept = 2

The volume of water in a conical water reservoir can be calculated using the formula for the volume of a cone, substituting the values for the radius and height of the water.

In this problem, we are trying to calculate the volume of water in a water reservoir that is shaped as a right circular cone. We are told that this cone has a depth of 21ft and a radius of 7ft, while the water in the cone has a depth of x ft and a radius of 3ft.

In order to solve this problem, we first need to understand that the volume V of a cone is calculated using the formula, V = 1/3πr²h, where r is the radius and h is the height of the cone. This formula can be applied to determine the volume of water in the cone.

Substituting the given values into the formula, the volume of the water would be as follows: V = 1/3 * π * (3ft)² * x ft.

Answer: Third option

[tex]u = -\frac{5\sqrt{29}}{29}i -\frac{2\sqrt{29}}{29}j[/tex]

Step-by-step explanation:

A unit vector [tex]u[/tex] is a vector that has magnitude 1.

To find a unit vector in the direction of the vector v we must first calculate the magnitude of v and then divide the vector v by its magnitude

The vector v is:

v = -5i - 2j

The magnitude of the vector is:

[tex]| v | =\sqrt{(-5)^2 +(-2)^2}\\\\|v|= \sqrt{29}[/tex]

Now we divide the vector v by its magnitude

[tex]u = \frac{1}{\sqrt{29}}v[/tex]

[tex]u = -\frac{5}{\sqrt{29}}i -\frac{2}{\sqrt{29}}j[/tex]

Simplifying we have to

[tex]u = -\frac{5\sqrt{29}}{29}i -\frac{2\sqrt{29}}{29}j[/tex]

Final answer:

To find the unit vector u in the direction of v = -5i - 2j, compute the magnitude of v and then divide each component of v by this magnitude. The result is u = (-5/√(29))i + (-2/√(29))j.

Explanation:

The question involves finding a unit vector in the direction of a given vector v = -5i - 2j. A unit vector is a vector with a magnitude of 1 that points in the direction of a given vector. To find the unit vector u in the direction of v, we first calculate the magnitude of v and then divide each component of v by its magnitude.

Upon calculating, the magnitude of v is sqrt(29), so the unit vector is u = (-5/√(29))i + (-2/√(29))j.
