24/25

Answer:

The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2

Step-by-step explanation:

The functions given to us is:

f(x) = 3(x - 1)² + 2

As there is no limitation of x, all value of x are possible. So

Domain = All real numbers

For all values of x, the minimum value of y is 2 calculated at x = 1. The rest of the values are greater than 2. So,

Range = y ≥ 2

Simplifying the function:

f(x) = 3(x² + 1² - 2(x)(1)) + 2

f(x) = 3(x² - 2x + 1) +2

f(x) = 3x² - 6x + 3 + 2

f(x) = 3x² - 6x + 5    (ax² + bx + c)

where a = 3, b = -6, c = 5

x-coordinate of Vertex is given as:

Vertex(x) = -b/2a = 6/2(3)

Vertex(x) = 1

Substitute x=1 in the function, we get

Vertex(y) = 2

So Vertex is at (1,2)

Answer: A. The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2.

Step-by-step explanation:

I just took the test and A. is the correct answer!

Answer:

The sequence is an arithmetic sequence.

Common difference = 0.6

Step-by-step explanation:

Given

-2.8, -2.2, -1.6, -1.0

Required

State if it's an arithmetic progression

Also state its common difference

To know if a sequence is arithmetic or not, we simply check for common difference

Common difference is calculated by subtracting a lower term with its immediate higher time;

In other words

[tex]Common difference = T_2 - T_1 = T_3 - T_2 = T_4 - T_3 = ......[/tex]

Where T represent Term and the number represent their positions;

So, from the given above

[tex]T_1 = -2.8\\T_2 = -2.2\\T_3 = -1.6\\T_4 = -1.0[/tex]

Calculating [tex]T_2 - T_1[/tex]

[tex]T2 - T1 = -2.2 - (-2.8)\\T2 - T1 = -2.2 + 2.8\\T2 - T1 = 0.6\\[/tex]

Calculating [tex]T_3 - T_2[/tex]

[tex]T_3 - T_2 = -1.6 - (-2.2)\\T_3 - T_2 = -1.6 + 2.2\\T_3 - T_2 = 0.6[/tex]

Calculating [tex]T_4 - T_3[/tex]

[tex]T_4 - T_3 = -1.0 - (-1.6)\\T_4 - T_3 = -1.0 + 1.6\\T_4 - T_3 = 0.6[/tex]

Notice that all the above workings gave the same result;

This shows that the sequence is an arithmetic sequence.

The result of each workings above is the common difference

Common difference = 0.6

Answer:

≈ 7 hours

Step-by-step explanation:

Maria can do full job in 13 hours,

she can do 1/13 part of job in one hour

Felipe can do full job in 15 hours,

he can do 1/15 part of job in 1 hour

Together they can do:

to complete full job they need:

Answer:

7 hr 10 min 12 seconds

Step-by-step explanation:

Maria, an experienced shipping clerk, can fill a certain order in 13 hours. Felipe, a new clerk, needs 16 hours to do the same job. Working together, how long will it take them to fill the order?

------------------------

Maria rate = 1/13 job/hr

-----

Felipe rate = 1/16 job/hr

----

Together rate = 1/x job/hr

-------

Equation:

rate + rate = Together rate

1/13 + 1/16 = 1/x

----

16x + 13x = 13*16

------

29x = 13*16

Answer:1. 8.6  2. 9.4 3.8.5

Step-by-step explanation:

Answer: The first puppy would weigh: 8.6 ounces

The second puppy would weigh: 9.4 ounces

The third puppy would weigh: 8.5 ounces

Step-by-step explanation: The puppies weights were 6.5, 7.3, and 6.4 respectively. The question says each puppy gained 2.1 ounces

So just add 2.1 to each of the puppies weights:

6.5+2.1=8.6

7.3+2.1=9.4

6.4+2.1+8.5

Hope this helps :)

Answer:

the formula is V=BH

Step-by-step explanation:

if the prism is rectangular prism : it has three dimensions then V=length * height * width

V= L*H*W or V= base*H

or V=BH

in your question it does not show V=BH maybe it is misprint

The volume of the prism is V = Bh , where B is the base area and h is the height of the prism

A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.

The volume of a prism is the product of its base area and height

Volume of Prism = B x h

where B = base area of prism

h = height of prism

Given data ,

Identify the shape of the base of the prism: The base of the prism can be any polygon, such as a triangle, rectangle, or hexagon. It is important to identify the shape of the base because the formula for calculating the area of the base will depend on the shape.

Calculate the area of the base: Once the shape of the base has been identified, calculate the area of the base using the appropriate formula. For example, if the base is a rectangle, the area would be calculated as length x width.

Multiply the area of the base by the height of the prism: Once the area of the base has been calculated, multiply it by the height of the prism to get the volume. The height is the perpendicular distance between the two parallel bases of the prism.

Hence , by following these three steps, you can calculate the volume of a prism regardless of its shape, as long as you can identify the shape of the base and calculate its area.

Answer:

( f h ) (x)  = 6 x² - 1

Step-by-step explanation:

Step(i):-

Given f(x)   =  3 x - 4

         g (x)  = −x²+2 x−5

        h (x)  = 2 x² + 1

         j (x)    = 6 x + 2 - 8 x

        K (x)   = 3 x² - x + 7

Step(ii):-

( f h ) (x) = f ( h (x)) = f ( 2 x² + 1 )

                            =  3 (2 x² + 1 ) - 4

                            =  3 ((2 x² ) + 3 - 4

                           =   6 x² - 1

Final answer:-

∴ ( f h ) (x)  = 6 x² - 1

Answer:

The property of polynomial addition that says that the sum of two polynomial is always a polynomial is called closure property of addition or under addition.

Polynomials are closed under addition because when you add polynomials the letters and their exponents do no change, you just add the coefficients of the like terms (those with same letters raised to the same exponents), so the result will be other polynomial of the same kind, except for the terms that cancel (positive with negative) which does not change the fact that the result is still a polynomial.

In mathematics the closure property means that the result of an operation over a kind of "number" will result in a "number" of the same kind.

Answer:

4) 8^14

7) h^7

10) 29^8 over 10^8

Step-by-step explanation:

If the numbers have the same base, just add their exponents together. So 10 plus 4 is 14.

Same thing for the second problem, since you have the same base, just add the exponents together. 6 plus 1 is 7

The bases are the same so just add the exponents, 7 plus one is 8.

(-2.9)^8

Convert it into a fraction: -(29/10)^8

Raise the fraction to the power (8) and the numerator and denominator to that power: 29^8/10^8

Question:

What is the solution to the linear equation?

[tex]x - \frac{2}{3}x - \frac{1}{2} = \frac{1}{3} + \frac{5}{6}x[/tex]

Answer:

[tex]x = \frac{-5}{3}[/tex]

Step-by-step explanation:

Given

[tex]x - \frac{2}{3}x - \frac{1}{2} = \frac{1}{3} + \frac{5}{6}x[/tex]

Required

Simplify

[tex]x - \frac{2}{3}x - \frac{1}{2} = \frac{1}{3} + \frac{5}{6}x[/tex]

Add [tex]\frac{1}{2}[/tex] to both sides

[tex]x - \frac{2}{3}x - \frac{1}{2} + \frac{1}{2} = \frac{1}{3} + \frac{5}{6}x + \frac{1}{2}[/tex]

[tex]x - \frac{2}{3}x = \frac{1}{3} + \frac{5}{6}x + \frac{1}{2}[/tex]

Subtract [tex]\frac{5}{6}x[/tex] from both sides

[tex]x - \frac{2}{3}x - \frac{5}{6}x= \frac{1}{3} + \frac{5}{6}x + \frac{1}{2} - \frac{5}{6}x[/tex]

[tex]x - \frac{2}{3}x - \frac{5}{6}x= \frac{1}{3} + \frac{1}{2} + \frac{5}{6}x- \frac{5}{6}x[/tex]

[tex]x - \frac{2}{3}x - \frac{5}{6}x= \frac{1}{3} + \frac{1}{2}[/tex]

Take LCMs

[tex]\frac{6x - 4x -5x}{6}= \frac{2+3}{6}[/tex]

[tex]\frac{-3x}{6}= \frac{5}{6}[/tex]

Multiply both sides by 6

[tex]6 * \frac{-3x}{6}= \frac{5}{6} * 6[/tex]

[tex]-3x= 5[/tex]

Divide both sides by -3

[tex]\frac{-3x}{-3}= \frac{5}{-3}[/tex]

[tex]x = \frac{5}{-3}[/tex]

[tex]x = \frac{-5}{3}[/tex]

Answer:

A pair of intersecting straight lines which agrees with option A of the answers in the list

Step-by-step explanation:

Recall, how a cone is built, as the surface produced by a line (called the "generatrix") as it moves at a fixed angle pivoting around a fixed point that will become the "vertex" of the cone.

As a plane cuts the cone perpendicular to its base and passing through the vertex, it will just intersect the generatrix trajectory in exactly two locations.

Answer:

The constant 8 represents the height of the stack and hence the number of coasters.  (It represents the number of coasters.)

Step-by-step explanation:

The formula for finding the volume of a cylinder is

V = πr²h

If you we take π =3.14 and h = 1 cm, as given in the question, then we can rewrite the formula for the volume of one coaster as

V = 3.14 * r²

But the formula in this question is

V(r) = 8*3.14 * r² so this means that there are 8 coasters here hence the formula for one coaster being multiplied by 8.
