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]

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.

Step-by-step explanation:

If you divide 32 by 8, you get 4. And since she already drank a glass of water, you subtract 1 from 4, and you are left with 3.

Answer: 24.59 or 24.6

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

Answer:

yes

Step-by-step explanation:

its 62

Answer:

Yes 372 is divisible by 6.

Step 1:

Start by setting it up with the divisor 6 on the left side and the dividend 372 on the right side like this:

Step 2:

The divisor (6) goes into the first digit of the dividend (3), 0 time(s). Therefore, put 0 on top:

Step 3:

Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend.

Step 4:

Subtract the result in the previous step from the first digit of the dividend (3 - 0 = 3) and write the answer below.

Step 5:

Move down the 2nd digit of the dividend (7) like this:

Step 6:

The divisor (6) goes into the bottom number (37), 6 time(s). Therefore, put 6 on top:

Step 7:

Multiply the divisor by the result in the previous step (6 x 6 = 36) and write that answer at the bottom:

Step 8:

Subtract the result in the previous step from the number written above it. (37 - 36 = 1) and write the answer at the bottom.

Step 9:

Move down the last digit of the dividend (2) like this:

Step 10:

The divisor (6) goes into the bottom number (12), 2 time(s). Therefore put 2 on top:

Step 11:

Multiply the divisor by the result in the previous step (6 x 2 = 12) and write the answer at the bottom:

Step 12:

Subtract the result in the previous step from the number written above it. (12 - 12 = 0) and write the answer at the bottom.

Given:

The endpoints of MN are located at M (-4, 4) and N (2,-2).

Point P divides the line segment MN such that MP: PN = 2: 1

To find:

The coordinates of point P.

Solution:

Section formula: If a point divides a line segment in m:n, then coordinates of that point are

[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

Point P divides the line segment MN in 2:1. So,

[tex]P=\left(\dfrac{2(2)+1(-4)}{2+1},\dfrac{2(-2)+1(4)}{2+1}\right)[/tex]

[tex]P=\left(\dfrac{4-4}{3},\dfrac{-4+4}{3}\right)[/tex]

[tex]P=\left(\dfrac{0}{3},\dfrac{0}{3}\right)[/tex]

[tex]P=(0,0)[/tex]

Therefore, the coordinates of the point P are (0,0).

Step-by-step explanation:

The number of possible numbers that can take the place of the first two digits = 9 possible numbers each

The number of possible numbers that can take the place of the 3rd to the 9th digits = 10 possible numbers each

The number of possible numbers that can take the place of the 10th digits = 9 possible numbers each

The total number of possible numbers is given as follows;

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]

So, the value of p is 11.2

Answer:

(a) Segments AB and De are not congruent since their lengths are not equal.

(b) Yes, you get the same result. In both cases you must take the absolute value of the difference of the coordinates giving you the same result no matter in which order you subtract the coordinates of the points.

Step-by-step explanation:

(a)

To find the distance between any two points on the number line, take the absolute value of the difference of the coordinates of the points.

The coordinate of point P is p. The coordinate of point Q is q. PQ or QP, the distance between points P and Q, is:

PQ = QP = |p - q| = |q - p|

It does not make a difference in which order you find the diffeence of the coordinates.

Look at points A and B.

Point A has coordinate -2.

Point B has coordinate 3.

AB = |-2 - 3| = |-5| = 5

Now look at points D and E.

Point D has coordinate 10.

Point E has coordinate 14.

DE = |10 - 14| = |-4| = 4

AB = 5; DE = 4

Answer: The lengths of segments AB and DE are not equal, so the segments are not congruent.

(b)

The coordinate of point A is -2.

The coordinate of point C is 5.

AC = |-2 - 5| = |-7| = 7

If you subtract -2 from 5, and then take the absolute value, you get:

AC = |5 - (-2)| = |5 + 2| = |7| = 7

Again you get 7. The order in which you subtract the coordinates of the points does not affect the result since you take the absolute value of the difference in both cases.

AC =

Answer:

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.

D) y=5x-0.2. The first point (5,4) yields to:

4=5*5-0.2=24.8 Incorrect.

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
