2(2x^2-2x+5) and 2(40x^2-5x+4)

Step-by-step explanation:

Answer:

4x^2−4x+10 = 2(2x^2−2x+5)

2x^2+5x-82x^2+5x−8 = 2(−40x^2+5x−4)

Step-by-step explanation:

4x^2−4x+10

Factor 4x^2−4x+10

4x^2−4x+10

=2(2x^2−2x+5)

2x^2+5x-82x^2+5x−8

Factor 2x^2+5x−82x^2+5x−8

−80x^2+10x−8

=2(−40x^2+5x−4)

Answer:

In terms of x, the area is given by: [tex]A = 4x^2 - 9[/tex].

If x = 30 units, the area will be of 3591 units squared.

Step-by-step explanation:

Area of a parallelogram:

The area of a parallelogram of base b and height h is given by:

[tex]A = bh[/tex]

In this question:

We have that [tex]b = 2x + 3, h = 2x - 3[/tex].

So

[tex]A = (2x + 3)(2x - 3) = 4x^2 - 6x + 6x - 9 = 4x^2 - 9[/tex]

In terms of x, the area is given by: [tex]A = 4x^2 - 9[/tex]

If x = 30 units:

[tex]A = 4*30^2 - 9 = 4*900 - 9 = 3600 - 9 = 3591[/tex]

If x = 30 units, the area will be of 3591 units squared.

Answer:

The side length is approximately 13.2 inches

Step-by-step explanation:

Given

[tex]Volume = 2300in^3[/tex]

Shape: Cube

Required

Determine the side length

Represent each side with x.

So, we have:

[tex]Volume = x^3[/tex]

Substitute 2300 for Volume

[tex]2300 = x^3[/tex]

Take cube roots of both sides

[tex]\sqrt[3]{2300} = x[/tex]

[tex]x = \sqrt[3]{2300}[/tex]

[tex]x = 13.2\ in[/tex] -- approximated

Answer:

5/11

Step-by-step explanation:

P(atleast 1 red) = 1 - P(no red)

P(atleast 1 red) = 1 - [(6/11)(5/11) + (6/11)(6/11)]

P(atleast 1 red) = 5/11

Answer:

3 hours

Step-by-step explanation:

The difference between the initial temperature and the temperature after an hour is an increase of 5 degrees. Since we need to calculate the time it would take for the temperature to rise to 60 degrees we need to find the difference in degrees from the current temperature to 60 degrees.

60 - 45 = 15 degrees

Since 1 hour equals an increase of 5 degrees we need to divide 15 by 5 to calculate how many hours before the temperature increases to 60 degrees

15 / 5 = 3 hours

It will take 3 hours for the temperature to rise to 60 degrees.

Represent time with x, and the temperature with y.

So, the given parameters can be represented using the following ordered pairs

(x,y) = (0,40) (1, 45), (x,60)

Start by calculating the slope using:

[tex]m = \frac{y_2-y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{45 -40}{1-0}[/tex]

[tex]m = 5[/tex]

Calculate the slope again, using a different set of points.

So, we have:

[tex]m = \frac{60 - 45}{x - 1}[/tex]

This gives

[tex]m = \frac{15}{x}[/tex]

Multiply both sides by x

[tex]mx = 15[/tex]

Divide both sides by m

[tex]x = \frac{15}m[/tex]

Substitute 5 for m

[tex]x = \frac{15}5[/tex]

[tex]x = 3[/tex]

Hence, it will take 3 hours for the temperature to rise to 60 degrees.

Answer:

The answer is D

Step-by-step explanation:

The measure of the height of the pole (h) will be;

⇒ h = 24 ft.

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

We have to given that;

The length of the wire which connects the top of a utility pole to a point on the ground = 25 foot

And, A point on the ground located 7 feet away from the base of the pole.

Now,

Let the height of the pole = h

So, We can apply the Pythagoras theorem as;

⇒ 25² = h² + 7²

⇒ 625 = h² + 49

⇒ h² = 625 - 49

⇒ h² = 576

⇒ h = √576

⇒ h = 24 ft.

Thus, The height of the pole = 24 ft.

Answer:

x = 79.799

Step-by-step explanation:

Apply trigonometric ratio formula to find x.

Thus, find the adjacent side of each triangle using 40° and 65° as reference angles respectively.

✔️Adjacent length of the triangle with reference angle 40°:

tan (40) = 110/adj

adj*tan(40) = 110

Adjacent length = 110/tan(40)

Adjacent length = 131.093 (nearest thousandth)

✔️Adjacent length of the triangle with reference angle 65°:

tan (65) = 110/adj

adj*tan(65) = 110

Adjacent length = 110/tan(65)

Adjacent length = 51.294 (nearest thousandth)

✔️Find x:

x = 131.093 - 51.294

x = 79.799

Answer:

-20 12

Step-by-step explanation:

The new mean of candies = 20 and the standard deviation is 12.

Given that,
Guests at a picnic try to guess the number of candies in a jar.
Mean  = 85,  standard deviation = 12
the jar actually holds 105 candies,
Want to convert each guess to its error, that is, we'll subtract 105 from each guess.

The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.

Statistics is the study of mathematics that deals with relations between comprehensive data.

Since,

Mean  = 85,
jar actually holds 105 candies
New mean = 105 - 85
                = 20
Since,

When a certain value is subtracted from all the values standard deviation still remains the same.,so
Standard deviation = 12

Thus, the new mean of candies = 20, and the standard deviation is 12.

Answer:

a=0, b=7, c=3

Step-by-step explanation:

Addition

The following addition is shown, where a,b, and c are unknown:

 2.14a

+ 1.b25

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

  c.865

We'll determine the values of the unknown variables by following the rules of addition.

The last column shows a+5=5. Since a cannot be greater than 9, thus a must be 0.

a = 0

This sum produces no carry.

Now we have 4 + 2 = 6

This is already correct and no variable needs to be calculated

Now we have 1 + b = 8. This leads to b=8-1=7

b = 7

This sum produces no carry.

Finally: 2 + 1 = c. This implies that

c=3

Substituting in the addition:

 2.140

+ 1.725
