with some functions, the value of the

dependent variable decreases as the value of the

independent variable increases. What is a real-world

example of this ?

12. 5x² - 180 = 0

5x² = 0 + 180

5x² = 180

x² = 180/5

x² = 36

x = √36

x = 6

13. 3x² - 100 = 332

3x² = 332 + 100

3x² = 432

x² = 432/3

x² = 144

x = √144

x = 12

14. ⅔x² - 8 = 16

⅔x² = 16 + 8

⅔x² = 24

2x² = 24 × 3

2x² = 72

x² = 72/2

x² = 36

x = √36

x = 6

15. ½x² - 5 = 5

½x² = 5 + 5

½x² = 10

x² = 10 × 2

x² = 20

x = √20

16. x² + 1 = 3x² - 13

1 + 13 = 3x² - x²

14 = 2x²

14/2 = x²

7 = x²

√7 = x

17. 2(x² + 4) = 10

2x² + 8 = 10

2x² = 10 - 8

2x² = 2

x² = 2/2

x² = 1

x = √1

x = 1

18. 3(x² - 1) = 9

3x² - 3 = 9

3x² = 9 + 3

3x² = 12

x² = 12/3

x² = 4

x = √4

x = 2

19. 2(x + 3)² = 8

2(x² + 3² + 2×x×3) = 8

2(x² + 9 + 6x) = 8

2x² + 18 + 12x = 8

2x² + 12x = 8 - 18

2x² + 12x = -10

2(x² + 6x) = -10

x² + 6x = -10/2

x(x + 6) = -5

x + 6 = -5/x

6 = -5/x - x

6 = -5/x - x²/x

6 = (-5 -x²)/x

6x = -5 - x²

Good Luck!

Answer:

0.243

Step-by-step explanation:

Given that :

Probability of success (p) = 76% = 0.76

Number of free throws (n) = 10

Probability of making 7 free throws = r

Using binomial distribution :

nCr * p^r * (1 - p)^(n-r)

10C7 * 0.76^7 * (1 - 0.76)^(10 - 7)

10C7 * 0.76^7 * 0.24^3

120 * 0.14645 * 0.013824

= 0.24294

Hence probability of making 7 free throws from 10 is 0.243

Answer:

Adam has to pay £173.40

Step-by-step explanation:

If you take 15 percent off of 80 you get 68 and if you multiply that by 2 then you will get 136. And 15 percent off of 40 is 34. Then you add 34 to 136 and you get 170. And 2 percent of 170 is 3.40. You add that to 170 and you get £173.40.

Step-by-step explanation:

Quadratic Equation

If the roots of a quadratic equation are known, we can form the equation as follows:

[tex]f(x)=a(x-x_1)(x-x_2)[/tex]

where x1 and x2 are the known roots, and a is the leading coefficient.

We are given the roots as x1=1 and x2=-6, and the leading coefficient as a=5, thus:

[tex]f(x)=5(x-1)(x+6)[/tex]

Operating:

[tex]f(x)=5(x^2-x+6x-6)[/tex]

Simplifying:

[tex]f(x)=5(x^2+5x-6)[/tex]

Multiplying:

[tex]\mathbf{f(x)=5x^2+25x-30}[/tex]

Answer:

You can put this solution on YOUR website!

the inequality is 500 - 25x >= 200

this insures that he will have at least 200 at the end of the summer.

subtract 200 from both sides of that inequality and add 25x to both sides of that inequality to get 500 - 200 >= 25x

simplify to get 300 >= 25x

divide both sides of that equation by 25 to get 300 / 25 >= x

simplify to get 12 >= x

12 >= x means x <= 12.

when x is smaller than or equal to 12, he will be guaranteed to have at least 200 in the account at the end of the summer.

when x = 12, what is left in the account is 500 - 25 * 12 = 200.

when x = 11, what is left in the account is 500 - 25 * 11 = 225.

when x = 13, what is left in the account is 500 - 25 * 13 = 175.

the maximum number of weeks he can withdraw money from his account is 12.

Answer:

I believe it it 13 miles per hour.

Step-by-step explanation:

       We know that an object travels 270 miles, so the rate is 270 miles.

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

                                                      6 hours

1 mile = 5,280 feet                                            1 day = 24 hours

5,280 x 270 = 425,600                                    1 hour = 3600 seconds

270 miles = 425,600 feet                                 3600 x 6 = 21,600

                                                                           3600 x 24 = 86,400

  Fraction:                                                                  Fraction:

425,600 feet        4,256 ft                                      21,600 sec           1

     -------          =       -----                                             ------------   =     --------  hour

 5,280 feet            528 ft                                        86,400 sec           4

4,256/528 ÷ 1/4 = 4,256/528 x 4/1 (reciprocal) = 17,024/528 = 439/33 = 13

Answer:

A. y + 1 = -3(x - 4)

Step-by-step explanation:

If the equations are perpendicular, then that means they have the same slope, just with the opposite sign. In this case, the given equation's slope is 3, which means that the other equation's slope is -3. Now that we know the slope and one point, we can write the equation in point-slope form:

y - y1 = m(x - x1)

y - (-1) = -3(x - 4)

y + 1 = -3(x - 4)

The equation in point-slope form is answer choice A. y + 1 = -3(x - 4).

Answer:

1536 and 6144

Step-by-step explanation:

you are multiplying by 4

I hope this helps you to understands better

The next two-term of the sequence is 1536 and 6144 and the multiplicity is 4

Given the sequence of numbers expressed as 6, 24, 96, 384, ...

The given sequence is a geometric sequence. The nth term of the sequence is expressed as;

[tex]T_n = ar^{n-1}[/tex]

a is the first term

r is the common ratio or multiplicity

n is the number of terms

Given the following parameters

a = 6

r = 24/6 = 96/24 = 4

n = 5 and 6 (5th and 6th term)

For the fifth term;

[tex]T_{5} = 6(4)^{5-1}\\T_5=6(4)^4\\T_5 = 1536[/tex]

For the sixth term;

[tex]T_{6} = 6(4)^{6-1}\\T_6=6(4)^5\\T_6 = 6144[/tex]

Hence the next two-term of the sequence is 1536 and 6144 and the multiplicity is 4

Step-by-step explanation:

g/b = 6/5

g = (6/5)b

g + b = 33

---

g + b = 33

(6/5)b + b = 33

(6/5)b + (5/5)b = 33

(11/5)b = 33

b = 33(5/11)

Answer:

18 girls

Step-by-step explanation:

Because you have to add the 5 and 6 to get 11. And then you divide the total amount of students (33) by the 11 you got earlier which you get a 3 from.Then you multiply the 3 times the number of girls (6) to get 18 girls. And you would multiply the 3 times the 5 if you wanted to find the number of boys in the art class.

Answer:

Step-by-step explanation:

The measure of angle 1 is equal to the measure of angle 2, its proved by using the theorem angle of tangency using arc measure.

Let A be a point on a circle and B be the point where a tangent (passing through B and C) intersects the circle. Then, the angle of tangency ∠ABC is half of the measure of the arc AB formed on the same side.

Given that, Arc AB= Arc CD in circle P.

Here, Arc AB= 1/2 ×m∠1 ------(i)

Arc CD= 1/2 ×m∠2 ------(ii)

Equation (i) and (ii) are equal, we get

1/2 ×m∠1=1/2 ×m∠2

m∠1=m∠2

Hence, proved.
