Answer:

-87

Let's find the discriminant.

6x2+3x+4=0

Step 1: Find discriminant with a=6, b=3, c=4.

b2−4ac

=(3)2−4(6)(4)

=−87

For this case we have a quadratic equation of the form:

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

Where:

[tex]a = 6\\b = 3\\c = 4[/tex]

By definition, we have that the discriminant is given by:

[tex]D = b ^ 2-4 (a) (c)[/tex]

Substituting the values:

[tex]D = (3) ^ 2-4 (6) (4)\\D = 9-96\\D = -87[/tex]

Answer:

The discriminant of the given equation is:

[tex]D = -87[/tex]

Answer:

314 units²

Step-by-step explanation:

Centre of the circle = (0, 0)

Another point on the circle = (-6, -8)

[tex]\text {Radius = }\sqrt{(0 - (-6))^2 + (0- (-8))^2}[/tex]

[tex]\text {Radius = }\sqrt{6^2 + 8^2}[/tex]

[tex]\text {Radius = }\sqrt{100}[/tex]

[tex]\text {Radius = }10[/tex]

Area = π (10)² = 100π = 314 units²

Final answer:

The area of the circle is found by first calculating the radius using the distance formula, which is determined to be 10 units. Then, the area formula πr² is used to find that the area of the circle is 100π square units.

Explanation:

To find the area of the circle centered at the origin containing the point (-6, -8), we first need to determine the radius of the circle. The radius can be found using the distance formula for a point from the origin, which is √((-6)²+ (-8)²). After calculating the radius, we use the formula for the area of a circle, which is πr^2, to find the circle's area.

The distance from the origin to the point (-6, -8) is the radius (r) of the circle: r = √((-6)² + (-8)²) = √(36 + 64) = √100 = 10.

Now that we have the radius, we can calculate the area (A): A = πr² = π(10)² = 100π square units.

Answer:

B. 4 and 6 in

Step-by-step explanation:

The triangle inequality rule states: the length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides.

So for the first qualification, we can eliminate A, C, and D. Therefore the answer is B, 4 & 6 in

To check whether the given side-lengths can form a triangle, we have to use the Triangle Inequality Theorem. This theorem states that for any triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
Let's apply this theorem to each pair of side-lengths given in the options along with the third side of 10 inches:
Option A:
Sides are 3 in, 8 in, and 10 in. According to the Triangle Inequality Theorem, we need to check if:
- 3 + 8 > 10 (which is true, since 11 > 10)
- 3 + 10 > 8 (which is true, since 13 > 8)
- 8 + 10 > 3 (which is true, since 18 > 3)
Since all three conditions are satisfied, option A can form a triangle.
Option B:
Sides are 4 in, 6 in, and 10 in. According to the Triangle Inequality Theorem, we need to check if:
- 4 + 6 > 10 (which is not true, since 10 is not greater than 10)
- 4 + 10 > 6 (which is true, since 14 > 6)
- 6 + 10 > 4 (which is true, since 16 > 4)
Since not all conditions are satisfied (specifically, the sum of the two smaller sides is not greater than the third side), option B cannot form a triangle.
Option C:
Sides are 5 in, 15 in, and 10 in. According to the Triangle Inequality Theorem, we need to check if:
- 5 + 15 > 10 (which is true, since 20 > 10)
- 5 + 10 > 15 (which is not true, since 15 is not greater than 15)
- 15 + 10 > 5 (which is true, since 25 > 5)
Since not all conditions are satisfied, option C cannot form a triangle.
Option D:
Sides are 6 in, 18 in, and 10 in. According to the Triangle Inequality Theorem, we need to check if:
- 6 + 18 > 10 (which is true, since 24 > 10)
- 6 + 10 > 18 (which is not true, since 16 is not greater than 18)
- 18 + 10 > 6 (which is true, since 28 > 6)
Since not all conditions are satisfied, option D cannot form a triangle.
Therefore, the only option that satisfies the Triangle Inequality Theorem and thus can be the measures of the other two sides of the triangle with one side measuring 10 inches is:
Option A: 3 in & 8 in.

So 4 divided by the sum of x and 7 = 4 / (x + 7)

Answer

  4

-------

x + 7

Final answer:

The correct way to write the expression '4 divided by the sum of x and 7' is 4 / (x + 7), which is not represented in any of the given options.

Explanation:

The expression 4 divided by the sum of x and 7 is written mathematically as 4 / (x + 7). None of the provided options A) 4 + 7 x, B) x 4 + 7, C) x + 7 4, or D) 4 x + 7 correctly represent this expression. The correct notation for division by a sum involves placing the sum in the denominator inside parentheses to ensure the correct order of operations is followed.

Answer:

# The transformation of f(x) to be g(x) is

- Reflected across the x-axis

- Translated 7 units to the left

- Translated 6 units up

# The transformation of f(x) to be g(x) is

- Reflected across the y-axis

- Translated 7 units down

Step-by-step explanation:

* Lets revise some transformation rules

* Lets talk about the transformation

- If the function f(x) reflected across the x-axis, then the new

 function g(x) = - f(x)

- If the function f(x) reflected across the y-axis, then the new

 function g(x) = f(-x)

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

* Lets solve the problems

# f(x) = 2^x ⇒ g(x) = -(2)^(x + 7) + 6

- There is a -ve sign in-front of the 2

∵ f(x) will be -f(x)

∴ f(x) will reflect across the x-axis ⇒ (1)

- The power x becomes x + 7

∵ -f(x) will be -f(x + 7)

∴ -f(x) will translate 7 units to the left ⇒ (2)

- after that -f(x + 7) add by 6

∴ -f(x + 7) will translate 6 units up ⇒ (3)

- From (1) , (2) , (3)

∴ The transformation of f(x) to be g(x) is

- Reflected across the x-axis

- Translated 7 units to the left

- Translated 6 units up

# f(x) = ㏒(x) ⇒ g(x) = ㏒(-x) - 7

- The (x) will be (-x)

∵ f(x) will be f(-x)

∴ f(x) will reflect across the y-axis ⇒ (1)

- after that f(-x) subtracted by 7

∴ f(-x) will translate 7 units down ⇒ (2)

- From (1) , (2)

∴ The transformation of f(x) to be g(x) is

- Reflected across the y-axis

- Translated 7 units down

Answer: b/t = 1/2  (or) 0.5

Step-by-step explanation:

a+b/ a =3

a+b =  3a

b = 3a-a

b = 2a

t+a/a = 5

t+a = 5a

t = 5a-a

t = 4a

b/t = 2a /4a

     = 1/2

The value of b/t is 1/2.

We have,

(a + b) / a = 3 ...(Equation 1)

(t + a) / a = 5 ...(Equation 2)

Let's solve Equation 1 for b:

(a + b) / a = 3

Multiplying both sides by a:

a + b = 3a

Subtracting a from both sides:

b = 3a - a

b = 2a ...(Equation 3)

Now, let's solve Equation 2 for t:

(t + a) / a = 5

Multiplying both sides by a:

t + a = 5a

Subtracting a from both sides:

t = 5a - a

t = 4a ...(Equation 4)

Now, let's substitute these values into the expression b/t:

b/t = (2a) / (4a)

b/t = 2a / 4a

b/t = 1/2

Therefore, the value of b/t is 1/2.

Step-by-step explanation:

To find this, we need to understand the combination formula.

If we have n items and we want to choose r at a time, we use the formula:

[tex]nCr=\frac{n!}{(n-r)!*r!}[/tex]

Where n! means n(n-1)(n-2)....

So we want 9C3, plugging them into the formula and doing some arithmetic, we have:

[tex]nCr=\frac{n!}{(n-r)!*r!}\\9C3=\frac{9!}{(9-3)!*3!}\\=\frac{9!}{6!*3!}\\=\frac{9*8*7*6!}{6!*3*2*1}\\=\frac{9*8*7}{3*2*1}\\=84[/tex]

Rearrange the data in ascending order

33, 36, 37, 38, 41, 42, 46, 49, 50, 50, 51, 52, 53, 54

The median is the middle value of the data or if there is no exact value at the middle then it is the average of the 2 values either side of the middle

Here the median is between 46 and 49

median = [tex]\frac{46+49}{2}[/tex] = 47.5

The upper quartile is the middle value of the data to the right of the median

[tex]Q_{3}[/tex] = 51

The lower quartile is the middle value of the data to the left of the median

[tex]Q_{1}[/tex] = 38

The minimum value = 33

The maximum value = 54

The lower quartile is the left side of the box plot

The upper quartile is the right side of the box plot

Step-by-step explanation:

Given that after dinner, your aunt serves slices of apple pie.

Central angle of a circle determines the area of the sector

Slice of apple pie here represents the sector area.

Area of a sector = [tex]\frac{x}{360} (\pi r^2)[/tex]

i.e. when central angle increases area also increases.

Comparing one radian and 60 degrees, we get
