Answer:

x = -0.5 or 6

Step-by-step explanation:

→ First find the first set of terms in brackets

( 2x + ? ) ( x - ? )

→ Find 2 numbers which multiply to give -6 and subtract to give -11 when multiplied by 2

( 2x + 1 ) ( x - 6 ) = 0

→ Now solve

x = -0.5 or 6

Answer:

x = 6 and -0.5

Step-by-step explanation:

Equation; 2x² - 11x - 6 = 0

a = 2

b = -11

c = -6

Substitute in the values of the equation for the quadratic formula;

-b ± [tex]\sqrt{b^2 - 4ac}[/tex] / 2a

-(-11) ± [tex]\sqrt{(-11)^2 - 4(2)(-6)}[/tex] / 2(2)

11 ± [tex]\sqrt{121+48}[/tex] / 4

11 ± 13 / 4

=> 11 + 13 / 4 = 6

=> 11 - 13 = -0.5

So;

x = 6 and -0.5

Answer:

The independent variable (IV) is the depths at the Altantic Ocean and the dependent variable (DV) is the water temperatures.

Step-by-step explanation:

The IV is what is changed between the groups of the study.

The DV is what is being measured for the groups.

You can say that the DV depends on the IV because changes and differences in the DV depends on the changes for the IV.

Answer:

h = 5

Step-by-step explanation:

6/8 - h/8 = 1/8

Multiply each side by 8 to clear the fractions

8*(6/8 - h/8) = 1/8*8

6 - h = 1

Subtract 6 from each side

6-h-6 = 1-6

-h = -5

Multiply each side by -1

h = 5

Answer:

[tex]h = 5[/tex]

Step-by-step explanation:

Solve the equations:

[tex] \frac{6}{8} - \frac{h}{8} = \frac{1}{8} [/tex]

Reduce fractions to the lowest term by canceling the greatest common factor:

[tex] \frac{3}{4} - \frac{h}{8} = \frac{1}{8} [/tex]

Rerreange unknown terms to the left side of the equation:

[tex] - \frac{h}{8} = \frac{1}{8} - \frac{3}{4} [/tex]

Find the common denominator and write the numerator above common denominator:

[tex] - \frac{h}{8} = \frac{1 - 6}{8} [/tex]

Calculate the sum or difference:

[tex] - \frac{h}{8} = \frac{ - 5}{8} [/tex]

Reduce the greatest common factor on both sides of the equation:

[tex] - h = - 5[/tex]

Divide both sides of the equation by the coefficient variable:

[tex]h = 5[/tex]

Step-by-step explanation:

When there is no linear term in the equation, the axis of symmetry is x=0.

__

The values 'a' and 'c' represent a vertical scale factor and a vertical translation, respectively. They do not change the axis of symmetry from that of the parent function, which is x=0.

Answer:

the probability that it will be either red or blue is 7/9

Step-by-step explanation:

There are 9 disks altogether.  Since there are 4 red disks, the probability that a red disk will be drawn is 4/9.  The probability that a blue disk will be drawn is 3/9.  These two events are independent of one another.

The probability that it will be either red or blue is that of the union of the two events.  Thus, we add together 4/9 and 3/9, obtaining 7/9

Given:

Center of the circle P = (-4,7)

Point on the circle = (-1,9).

To find:

The equation of the circle P.

Solution:

The standard form of a circle is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]                  ...(i)

Where, (h,k) is the center and r is the radius of the circle.

Center of the circle is at point (-4,7). So, [tex]h=-4,k=7[/tex].

The center passes through the point (-1,9). So, the distance between the point (-1,9) and the center (-4,7) is the radius.

Distance formula:

[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using the distance formula, we get

[tex]r=\sqrt{(-4-(-1))^2+(7-9)^2}[/tex]

[tex]r=\sqrt{(-3)^2+(-2)^2}[/tex]

[tex]r=\sqrt{9+4}[/tex]

[tex]r=\sqrt{13}[/tex]

Substituting [tex]h=-4,k=7[/tex] and [tex]r=\sqrt{13}[/tex] in (i), we get

[tex](x-(-4))^2+(y-7)^2=(\sqrt{13})^2[/tex]

[tex](x+4)^2+(y-7)^2=13[/tex]

Therefore, the equation of the circle P is [tex](x+4)^2+(y-7)^2=13[/tex].

The equation of the circle P  is (x +4)² + (y-7)² = 13

The standard equation for a circle is

(x - h)² +(y-k)² = r²

here the centre of the circle is (h,k) and r is the radius

It is given that

Circle P is graphed in the coordinate plane with centre (- 4, 7)

The equation can be written as

(x +4)² + (y-7)² = r²

It is also given that

Circle P contains the point (-1,9)

Therefore

( -1 +4)² + (9-7)² = r²

3² + 2² = r²

r² = 9+4 = 13

r = √13

Therefore the equation of the circle P  is

(x +4)² + (y-7)² = 13

Answer:A

Step-by-step explanation:

Step-by-step explanation:

First of all, we'll have to eliminate 4/8 and 3/7 because they're both 1/2 or smaller and 5/9 is bigger than 1/2.

That leaves 7/13 and 6/10. 6/10=54/90    and 5/9 is 50/90.

So 6/10 is the correct answer

Answer:

f(x) approaches positive infinity.

g(x) approaches negative infinity.

the y-intercept of f(x) is less than the y-intercept of g(x).

Step-by-step explanation:

the highest power of x in f(x) is 3, and it has a positive sign. so, the bigger x the more the x³ part will dominate.

therefore, with x going to positive infinity, also f(x) goes to positive infinity.

the graph of g(x) clearly dives down never to come back up or flatten out. so, with x going to positive infinity, g(x) goes to negative infinity.

the y-intercept of f(x) = f(0).

that means the functional value when x=0.

so, for x=0 this means

y = 2×0³ - 3×0² + 5×0 + 7 = 7

the graph of g(x) shows that g(0) is 8.

so f(0) is less than g(0).

As x approaches positive infinity, f(x) approaches positive infinity and g(x) approaches negative infinity. The y-intercept of the function f is 7 and the y-intercept of function g is 8. #SPJ5

Polynomials are algebraic expressions whose form is described below:

[tex]y = \sum \limits_{i = 0}^{n} c_{i}\cdot x^{i}[/tex]     (1)

Where [tex]c_{i}[/tex] is the i-th coefficient of the polynomial.

In this question we have two polynomials in two distinct presentations, an analytical and a graphical one, whose behaviors must be analyzed to fill the blanks of the paragraph given. The complete paragraph is shown below:

Answer:

BC = 17.1

m<B = 6.7 deg

m<C = 83.3 deg

Step-by-step explanation:

Find BC

a^2 + b^2 = c^2

AC^2 + AB^2 = BC^2

2^2 + 17^2 = BC^2

4 + 289 = BC^2

BC^2 = 293

BC = sqrt(293)

BC = 17.1

Find <B

tan B = opp/adj

tan B = 2/17

B = tan^-1 2/17

B = 6.7 deg

Find <C

m<A + m<B + m<C = 180

90 + 6.7 + m<C = 180

m<C = 180 - 90 - 6.7

m<C = 83.3

Answer:

The answer should be 93.

Step-by-step explanation:

So this took a lot of work to figure out, I did not solve it normally.

What i first did was add 75, 80, and 92 to get = 247. 247/3 was only 82, but in the equation you said the score on her next quiz, which means I would need to divide by 4.

But that was not possible with the numbers I had.

i started adding numbers to see if I would get the mean of 85, and eventually I added 93. to get 340, which I divided by 4 (the number of quizzes that were taken) to get the mean of 85.

so yeah, I made it more complicated than it need to be, but that's the answer lol
