Answer:

f(5) = 100

f(25) = 500

f(60) = 1200

Step-by-step explanation:

All you had to do was pulug in the f(x) into the x.

F(5) = 20 (5) = 100

f(25) = 20(25) = 500

f(60) = 20(60) = 1200

Answer:

w = 0.5 because if you mesure it with a ruler you’d get that answer.

The area of the mat with the painting will be equal to (W+10)(W+16) square inches.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

Given that the sides of the rectangle are 16 inches and 10 inches. The extra width of the mat is w inch on each side.

The total sides of the total painting and the mat will be,

Length = L + W=16 +W

Width = 10 + W= 10 +W

The area will be calculated as,

A = ( 16 + W ) ( 10 + W )

Therefore, the area of the mat with the painting will be equal to (W+10)(W+16) square inches.

Answer:

a. The number of people that receive the text in the fourth round are 10³ people

b. The total number of people that receive the text are 1.1111 × 10⁴ people

Step-by-step explanation:

a. The given information are;

The number of people the text is sent to in the first round = 1

In the second round, the number of people the text is sent to by people in the first round = 10

In the third round, the number people the text is sent to by the 10 people in the second round = 10 × 10 = 100 people = 10² people

In the fourth round, the number of people the text is sent to by the people in the third round = 100 × 10 = 1000 people = 10³ people

The number of people that receive the text in the fourth round = 10³ people

b. In the fifth round, the number of people, the people in the fourth round send the text to = 1000 × 10 = 10000 people = 10⁴ people

The total number of people that receive the text = 1 + 10 + 10² + 10³ + 10⁴ people =  11111 people = 1.1111 × 10⁴ people

Answer: 24.59 or 24.6

Step-by-step explanation: You do the formula A squared+ B squared= C squared. You substitute A and B because you already know them which will make it 11 squared+22 squared=24.6(rounded)

C is larger than both A and B remember that

So, the first blank is for what kind of angle it is: acute, obtuse, reflex, straight, or right. The second blank is for what the measure of the angle is. You can find that out by looking at the protractor. It should tell you what the measure of the angle is. You can read the protractor by looking at the numbers. The numbers are the degrees of incline the angle measures, which is what you're looking for.

Answer:

[tex]\displaystyle x_1=\frac{7+ \sqrt{85}}{6}\approx 2.70\\\displaystyle x_2=\frac{7- \sqrt{85}}{6}\approx -0.37[/tex]

Step-by-step explanation:

Quadratic Formula

Given the second-degree equation:

[tex]ax^2+bx+c=0[/tex]

The solutions of the equation can be obtained by applying the formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

The equation to solve is:

[tex]3x^2-7x-3=0[/tex]

Which means the values of the coefficients are: a=3, b=-7, c=-3. Substituting the values in the formula:

[tex]\displaystyle x=\frac{-(-7)\pm \sqrt{(-7)^2-4(3)(-3)}}{2(3)}[/tex]

[tex]\displaystyle x=\frac{7\pm \sqrt{49+36}}{6}[/tex]

[tex]\displaystyle x=\frac{7\pm \sqrt{85}}{6}[/tex]

There are two real solutions for this equation:

[tex]\displaystyle x_1=\frac{7+ \sqrt{85}}{6}[/tex]

[tex]\displaystyle x_2=\frac{7- \sqrt{85}}{6}[/tex]

The approximate values of both roots are:

[tex]x_1\approx 2.70[/tex]

[tex]x_2\approx -0.37[/tex]

Answer:

t = 9

Step-by-step explanation:

Here, we want to find the value of t

2(t-3)^2 -72 = 0

2(t-3)^2 = 72

divide both sides by 2

(t-3)^2 = 72/2

(t-3)^2 = 36

(t-3)^2 = 6^2

Since powers are equal, we equate base

t-3 = 6

t = 6 + 3

t = 9

Answer:

A. by the definition of perpendicular.

Explanation:

Indeed, in geometry, for lines to be termed as been perpendicular, it means that two lines met at a right angle (90 degrees).

From the attached image we could see that Segment PR is perpendicular to segment QS as it touches or meets with segment QS which follows the definition of perpendicular. Also, Angle QRP is a right angle because it is exactly 90 degrees.

a. the domain is the horizontal extent, (-∞, ∞)

b. the range is the vertical extent, [-4, ∞)

c. the function is increasing where it goes up to the right, (2, ∞)

d. the function is decreasing where it goes down to the right, (-∞, 2)

e. the function is positive where it is above the x-axis, (-∞, 0) ∪ (4, ∞)

f. the function is negative where it is below the x-axis, (0, 4)

g. the function extends to ∞, so has no maximum value

h. the vertex is the low point, or minimum value, -4

i. the function increases from -4 to 0 on the interval [2, 4] so has an average rate of change of (0 -(-4))/(4 -2) = 4/2 = 2

Answer:

[tex]\frac{x}{5}[/tex] > 22

x = > 110

Step-by-step explanation:

This is the answer because:

1) The quotient of x and 5 means the answer to a division problem. Therefore, it's [tex]\frac{x}{5}[/tex]

2) Greater than 22 means the quotient has to be anything greater than 22. Therefore it is > 22

3) Finally, x is equal to anything greater than 110 because 22 x 5 is 110. Therefore, x has to equal anything greater than 110

The final answer is:

[tex]\frac{x}{5}[/tex] > 22

x = > 110

Area = length x width.

Divide the area by the length of find the width.

Width = 375/25 = 15 feet.

The perimeter is the sum

Of the 4 sides.

Perimeter = 25 + 25 + 15 + 15 = 80 feet.

The perimeter of a rectangle is 80 feet.

Given that, the length of a rectangle=25 feet and area of the rectangle=375 square feet.

We need to find the perimeter of a rectangle.

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

We know that, the area of a rectangle=length×width

Now, the area of a rectangle=25×width

⇒375=25×width

⇒Width=15 feet

So, perimeter = 2(25+15).

=80 feet

Therefore, the perimeter of a rectangle is 80 feet.

Answer:

p = 11.2

Step-by-step explanation:

Given equation is :

2.6(5.5p – 12.4) = 127.92

Using the distributive property :

14.3p - 32.24 = 127.92

Using addition property :

14.3p - 32.24 + 32.24= 127.92 + 32.24 (adding 32.24 to the both sides)

14.3p = 160.16

Using division property :

[tex]p=\dfrac{160.16}{14.3}\\\\p=11.2[/tex]

y=-0.2x+5. Correct choice: A)

Step-by-step explanation:

Modeling With Equations

Let's call x the number of minutes and y the distance from home. The correct model should meet both conditions:

After 5 minutes, Ye is 4 miles from home. This is the ordered pair (5,4)

After 15 minutes, Ye is 2 miles from home. This is the ordered pair (15,2)

A) y=-0.2x+5. Testing the first point (5,4): y=-0.2*5+5=4. Correct

Testing the second point (15,2): y=-0.2*15+5=2. Correct

This is the correct choice.

B) y=11/7x-27/7. Testing the first point: (5,4) y=11/7*5-27/7=4. Correct

Testing the second point (15,2). y=11/7*15-27/7=138/7. Incorrect

Incorrect choice.

C) This equation is equal to the choice B), thus this one is incorrect.

Answer:

720 possible arrangements.

Step-by-step explanation:

The possible arrangement of the cars, given that the three cars of the same color are kept together is 4320.

The combination is a way of selecting items from a collection where the order of selection does not matter.

We have,

Number of cars = 8

Number of cars that are the same in color = 3

Cars that are the same in color can be arranged = 3!

There are 8 cars such that,

1 2 3 4 5 6 7 8

Three cars of the same color are taken out and we have,

1  2  3  4  5

We see that there are six spaces = 6!

where we can put the same color cars together so,

The possible arrangement of the cars, given that the three cars of the same color are kept together:

= 3! x 6!

= 3 x 2 x 1  x 6 x 5 x 4 x 3 x 2 x 1

= 4320

Thus,

The possible arrangement of the cars, given that the three cars of the same color are kept together is 4320.
