Which of the following terms does not describe a trapezoid? A. a parallelogram B. a polygon C. a quadrilateral D. a quadrangle

Answer:

60

Step-by-step explanation:

amount of money deposited for one week= $10

no. of weeks= 6

amount= 6*10=60

Jason will have saved $60 after 6 weeks by depositing $5 twice a week.

Jason deposits $5 into his savings account twice a week for 6 weeks. To calculate the total amount saved after 6 weeks, we can set up an equation where s stands for the amount of money saved:

s = number of deposits per week  * amount per deposit  * number of weeks

Plugging in the values we have:

s = 2 deposits/week * $5/deposit * 6 weeks

s = $60

Therefore, Jason will have saved $60 after 6 weeks.

Step-by-step explanation:

The formula of a volume of a prism:

[tex]V=BH[/tex]

B - base area

H - height

In the base we have the right triangle.

The formula of an area of a righ triangle

[tex]A=\dfrac{ab}{2}[/tex]

a, b - legs

We have a = 6.2m and b = 11m. Substitute:

[tex]B=\dfrac{(6.2)(11)}{2}=34.1\ m^2[/tex]

The height H = 9 m.

Substitute to the formula of a volume:

[tex]V=(34.1)(9)=306.9\ m^3[/tex]

to get the x coordinate increment

we subtract x coordinate D from F and would be (-6.5) - (-8.25)=1.75 and then divide it by two to get the increment of one step and that would be 1.75 / 2 =0.875

now we get the y coordinate increment

we subtract y coordinate D from F and would be (-7.5) - (-5.75)=-1.75 and then divide it by two to get the increment of one step and that would be -1.75 / 2 =-0.875

A = (D x coordinate - 1.75,D y coordinate +1.75) A=(-10,-4)

I = (H x coordinate + 0.875,d H coordinate -0.875)

I=(-3.875,-10.125)

Answer:

[tex](f+g)(x)=3^x+4x+8[/tex]

if [tex]f(x)=3^x+10[/tex] and [tex]g(x)=4x-2[/tex].

Step-by-step explanation:

We are given [tex]f(x)=3^x+10[/tex] and [tex]g(x)=4x-2[/tex].

We are asked to find [tex](f+g)(x)[/tex].

[tex](f+g)(x)[/tex] means [tex]f(x)+g(x)[/tex]

[tex](f+g)(x)=(3^x+10)+(4x-2)[/tex]

You only have one pair of like terms, that is the constants.

[tex](f+g)(x)=3^x+4x+10-2[/tex]

[tex](f+g)(x)=3^x+4x+8[/tex]

Answer:

(-3,2)

Step-by-step explanation:

When the point P(x,y) is reflected in the line [tex]x=k[/tex], the mapping is

[tex]P(x,y)\to P'(2k-x,y)[/tex].

The image of (1,2) after a  reflection about x = 6 is

[tex](1,2)\to (2\times6-1,2)[/tex].

[tex](1,2)\to (12-1,2)[/tex].

[tex](1,2)\to (11,2)[/tex].

When the resulting point is again reflected in the line x=4, we obtain

[tex](11,2)\to (2\times4-11,2)[/tex].

[tex](11,2)\to (8-11,2)[/tex].

[tex](11,2)\to (-3,2)[/tex].

Therefore the image of (1,2) after a

reflection about x = 6 followed by a

reflection about x = 4 is (-3,2)

Answer:

[tex]x^2-7x-10[/tex] is consider prime (also known as not factorable over the rationals)

Step-by-step explanation:

[tex]x^2-7x-10[/tex] is consider prime.

[tex]x^2-7x-10[/tex] comparing to [tex]ax^2+bx+c[/tex] gives you [tex]a=1,b=-7,c=-10[/tex].

Since a=1, all you have to do is find two numbers that multiply to be -10 and add up to be -7.

Here are all the integer pairs that multiply to be -10:

-1(10)

1(-10)

2(-5)

-2(5)

Now you will see none of those pairs adds to be -7:

-1+10=9

1+(-10)=-9

2+(-5)=-3

-2+5=3

So this is not factorable over the real numbers.

Now if you had something like [tex]x^2-7x+10[/tex], that would be a different story.  You can find two numbers that multiply to be 10 and add up to be -7.  Those numbers are -2 and -5 since -2(-5)=10 and -2+(-5)=-7. So the factored form of [tex]x^2-7x+10[/tex] is [tex](x-2)(x-5)[/tex].

Answer:

2x^2+3

Step-by-step explanation:

(3x^2 + 2x+4) - (x^2 +2x+1)

I'm going to rewrite this using distributive propery and without parenthesis:

3x^2 + 2x + 4 - x^2 - 2x - 1

Now I'm going to pair up any like terms by use of the commutative property.

3x^2 - x^2 + 2x - 2x + 4 - 1

Now simplify:

2x^2 + 0 +3

2x^2+3

Answer:

The final value of subtraction is 2x² + 3

Step-by-step explanation:

It is given that (3x² + 2x + 4) - ( x² + 2x + 1)

To find the value of subtraction

(3x² + 2x + 4) - ( x² + 2x + 1) =  (3x² + 2x + 4 -  x² - 2x - 1)

 = 3x² - x² + 2x - 2x + 4 - 1

 = 2x² + 0 +3

 = 2x² + 3

Therefore the final value of subtraction is 2x² + 3

Answer:

[tex]8(2x^2 + x + 4)[/tex]

Step-by-step explanation:

Given:

We'd factor out 8:

[tex]8(2x^2 + x + 4)[/tex]

Our answer would be [tex]8(2x^2 + x + 4)[/tex]

The completely factored form of the expression 16x2 + 8x + 32 is 8(2x2 + x + 4), after factoring out the greatest common factor, 8.

The question asks for the completely factored form of the expression 16x2 + 8x + 32. To factor this expression completely, we look for a common factor in all the terms. Observing the coefficients (16, 8, and 32), we recognize that 8 is the greatest common factor (GCF). Factoring out the GCF, we get:

8(2x2 + x + 4).

This expression cannot be factored further since the quadratic inside the parentheses does not factor neatly over the integers. Thus, the completely factored form of 16x2 + 8x + 32 is 8(2x2 + x + 4).

The domain of the function in the mapping given is: A. {x | x = -5, -3, 1, 2, 6}.

The domain of a function includes all the possible values of x (input) in a function.

The corresponding set of y-values (output) is the range of the function.

The set of x-values in the mapping are, -5, -3, 1, 2, 6.

Therefore, the domain of the function in the mapping given is: A. {x | x = -5, -3, 1, 2, 6}.

For this case we have a function of the form [tex]y = f (x)[/tex]. Where:

[tex]f (x) = x-4[/tex]

By definition, the domain of a function is represented by the set of values of the independent variable, x, for which the value of the variable y can be calculated.

For its part, the range is represented by the values of "and".

So:

[tex]f (1) = 1-4 = -3\\f (5) = 5-4 = 1\\f (6) = 6-4 = 2[/tex]

Thus, the range is {-3,1,2}

Answer:

So I did most of you table for you:

First blank:4

Second blank:-4

Third blank:-8

Fourth blank: Left to you: Just plug in 6 into 1/2x^2-5x+4 (I will check)

Fifth blank: Left to you: Just plug in 8 into 1/2x^2-5x+4 (I will check)

The graph is D.

Step-by-step explanation:

So they have a table to fill in and they tell you in the first row what they want you to plug in

So the table is asking us to answer this:

What is h(0),h(2),h(4),h(6), and h(8).

h(0) means to replace x with 0 in [tex]\frac{1}{2} x^2-5x+4[/tex].

[tex]\frac{1}{2}(0)^2-5(0)+4[/tex]

[tex]0-0+4[/tex]

[tex]0+4[/tex]

[tex]4[/tex]

So the first blank is 4 since h(0)=4.

h(2) means to replace x with 2 in [tex]\frac{1}{2} x^2-5x+4[/tex].

[tex]\frac{1}{2} (2)^2-5(2)+4[/tex]

[tex]\frac{1}{2} (4)-10+4[/tex]

[tex]2-10+4[/tex]

[tex]-8+4[/tex]

[tex]-4[/tex]

So the second blank is -4 since h(2)=-4.

h(4) means to replace x with 4 in [tex]\frac{1}{2} x^2-5x+4[/tex].

[tex]\frac{1}{2}(4)^2-5(4)+4[/tex]

[tex]\frac{1}{2}(16)-20+4[/tex]

[tex]8-20+4[/tex]

[tex]-12+4[/tex]

[tex]-8[/tex]

So the third blank is -8 since h(4)=-8

Maybe you can try the last 2 blanks in the table part. That is try computing h(6) and h(8). I will check it for you.

Now the points I have so far are (0,4) from the h(0)=4, (2,-4) from the h(2)=-4, and (4,-8) from the h(4)=-8.

I'm looking for a graph that goes through these points (0,4) , (2,-4) , and (4,-8).

By the way the only graphs that are worth looking at is C and D because they are open up.  I know my curve for h(x)=1/2x^2-5x+4 should be a parabola open up because 1/2 is positive and 1/2 is the coefficient of x^2.

So Graph C has y-intercept (0,10) not (0,4) so Graph C is not right.

Graph D has y-intercept (0,4).  It also goes through (2,-4) and (4,-8).  

I don't know if you notice but the x-axis and y-axis are going up by two's in each graph.

Answer:

c.

Step-by-step explanation:

the most that can be factored out is -1.5,

-1.5 * w = -1.5w

-1.5 * -5 = 7.5

-1.5w + 7.5, so it's

-1.5(w-5)

Using the Pythagorean theorem c^2 = a^2 + b^2

Where c is the hypotenuse and a and b are the side lengths.

c^2 = 12^2 + 16^2

c^2 = 144 + 256

c^2 = 400

c = √400

c = 20

The hypotenuse is 20 units.

Answer:

Hypotenuse = 20 units.

Step-by-step explanation:

Using the Pythagoras theorem:

h^2 = 12^2 + 16^2

h^2 = 144 + 256 = 400

h = 20.
