Which of the following is a binomial with degree 2?

A)2x^3 + xy

B)2xy^2

C)3x + 3x^2

D)2 + 5x-3x^3

Answer:

A)21

Step-by-step explanation:

Make them equal to each other, since they're congruent:

6x+2=128

Subtract 2 from both sides to get the x-term alone:

6x=126

Divide both sides by 6 to get x alone:

x=21

Answer:

No it will not form a right triangle it will form a SSS triangle

Step-by-step explanation:

The zeros of the quadratic function f(x) = 2x² + 8x – 3 is x = -2 - √11/4 and x = -2 + √11/4

A quadratic function is in the form:

y = ax² + bx + c

Given that:

f(x) = 2x² + 8x - 3, hence:

The zero is at:

2x² + 8x - 3 = 0

2x² + 8x = 3

Dividing through by 2:

x² + 4x = 3/2

add to both sides 4:

(x + 2)² = 3/2 + 4

(x + 2)² = 11/4

x + 2 = ±√11/4

x = -2 ±√11/4

The zeros of the quadratic function f(x) = 2x² + 8x – 3 is x = -2 - √11/4 and x = -2 + √11/4

Step-by-step explanation:

I got it right on edge

Step-by-step explanation:

l = length

w = width

l/w = 5/2

l = 5w/2

l×w = 1000ft²

(5w/2)×w = 1000

5w²/2 = 1000

5w² = 2000

w² = 400

w = 20ft

l = 5w/2 = 5×20/2 = 5×10 = 50ft

the length is 50ft.

the width is 20ft.

The trajectory of your message illustrates a quadratic function

The equation of the trajectory of the message is [tex]y = -\frac 15(x - 17)^2 + 20[/tex]

The trajectory graph (see attachment) is a quadratic function that passes through the following points:

(x,y) = (7,0) and (27,0)

And the vertex is:

(h,b) = (17,20)

A quadratic function is represented as:

[tex]y = a(x - h)^2 + b[/tex]

So, we have:

[tex]y = a(x - 17)^2 + 20[/tex]

Substitute (7,0) for (x,y)

[tex]0 = a(7 - 17)^2 + 20[/tex]

Evaluate

[tex]0 = 100a + 20[/tex]

Collect like terms

[tex]100a = -20[/tex]

Divide both sides by 100

[tex]a = -\frac 15[/tex]

Recall that:

[tex]y = a(x - 17)^2 + 20[/tex]

So, we have:

[tex]y = -\frac 15(x - 17)^2 + 20[/tex]

Hence, the equation of the trajectory of the message is [tex]y = -\frac 15(x - 17)^2 + 20[/tex]

Step-by-step explanation:

this is unclear.

did this mean the left and the right sides are the same length (and parallel)?

it seems then they are 2 congruent triangles and the whole shape a parallelogram.

remember, the sum of all 3 angles in any triangle is always 180°.

so,

angle 1 = 180 - 70 - 60 = 50°

the congruence principle then makes angle 3 = angle 1 = 50°.

and then angle 2 must be 70°, as 70° + angle 3 = angle 1 + angle 2.

if I misunderstood, then angle 3 and then angle 2 can't be determined.

In the question, we are informed:

2 1/2 cups sugar for the cake and 1 1/4 cup sugar for the vanilla icing are called for in Mr. Smith's recipe.

1st step

We total the amount of sugar he'll require.

1 1/4 + 2 1/2

(1/2 + 1/4) + (2 + 1)

= 3 + (2 Plus a quarter)

a total of 3 3/4 cups of sugar

2nd Step

How many 1/4 cup sugar scoops does he require?

This can be calculated as follows:

1/4 cup sugar 3 3/4 cup sugar

= 15/4 x 1/4 = 15/4 x 1/4 = 15/4 x 1/4 =

= 15/4/4 = 15/4/4 = 15/4/4 = 15/4/4 = 15/4

15 

As a result, he'll require 15, 1/4 cup sugar scoops.

Answer:

c) time using table; cost

Step-by-step explanation:

An independent quantity is the variable that can be controlled and changed. A dependent quantity is not controlled and is based on the changes to the independent quantity.

First, decide which quantity can be controlled. In this situation, the player gets to choose the amount of time for which they play. This means that the time using the table must be the independent quantity because it is controlled by the player.

The cost cannot be controlled. It is solely based on the amount of time played. This means that the cost is the dependent quantity in this situation.

The probability for a person to receive the newspaper at least one day per week is 83 %. Then the correct option is D.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

A local newspaper compiles data on the number of days, X, people in a neighborhood receive the newspaper.

The table will be

  X               P(X)

  0               0.17

  1                0.16

  2               0.14

  5               0.12

  7               0.41

We are asked the probability for a person to receive the newspaper at least one day per week. Then the probability will be

Probability = 0.16 + 0.14 + 0.12 + 0.41

Probability = 0.83

Probability = 83 %

There are different types of quadrilaterals, for example: square, rectangle, rhombus and trapezoid.  Each type is defined accordingly to its length of sides and angles. For example, the rhombus has diagonals bisect each other at 90°.

Here you can use the area of the rhombus that is:  [tex]A_{rhombus}=\frac{d1*d2}{2}[/tex], where:

d1 = length of diagonal 1

d2 = length of diagonal 2

Applying the previous formula, you will have:

Answer:

16.8

Step-by-step explanation:

The scale factor is a ratio. The surface area of the real ramp is 16.80 ft².

The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.

As we know that the height of the real ramp is 1.2 feet, while the height of the drawing is 6 cm, therefore, the scale factor can be written as,

[tex]\rm Scale\ factor = \dfrac{\text{Area of Image}}{\text{Area of pre-image}}=\dfrac{1.2 \ feet}{6\ cm} = 0.2[/tex]

Now, the area of the pre-image can be written as,

[tex]\rm \text{Area of pre-image} = 2triangles+ 2 rectangle + 1 rectangle\ at\ base[/tex]

                             [tex]= 2(0.5 \times 6 \times 16) + 2(10 \times 9) + (16 \times 9)\\\\= 2(48)+2(90)+144\\\\= 96 + 180 + 144\\\\ = 420\ cm^2[/tex]

Further, the area of the actual ramp can be written as,

[tex]{\text{Area of pre-image}} \times \rm Scale\ factor = \text{Area of Image}\\\\ \text{Area of Image}= 420 \times (0.2)^2 \\\\ \text{Area of Image}= 16.8\ ft^2[/tex]

Hence, the surface area of the real ramp is 16.80 ft².

The cost of the rectangular deck is: $0.08 per square foot.

Area of rectangular shape = length × width

The deck is rectangular.

Thus:

Cost of the deck per square foot = area of rectangular deck/total cost of deck.

Area of rectangular deck = 8.25 × 12.5 = 103.125

Cost of the deck per square foot = 103.125/1,270 = 0.08

Therefore, the cost of the rectangular deck is: $0.08 per square foot.
