Step-by-step explanation:

Answer:

[tex]x_1=4.158[/tex]

[tex]x_2=0.8416[/tex]

Step-by-step explanation:

For an equation of the form [tex]ax^2 +bx +c[/tex]

The quadratic formula is

[tex]\frac{-b\±\sqrt{b^2 -4ac}}{2a}[/tex]

In this case the equation is:

[tex]2x^2 - 10x + 7 = 0[/tex]

Then

[tex]a= 2\\b= -10\\c= 7[/tex]

Therefore, using the quadratic formula we have:

[tex]x=\frac{-(-10)\±\sqrt{(-10)^2 -4(2(7)}}{2(2)}[/tex]

[tex]x=\frac{5\±\sqrt{11}}{2}[/tex]

[tex]x_1=4.158[/tex]

[tex]x_2=0.8416[/tex]

ANSWER

[tex]x = \frac{ 5 }{2} - \frac{\sqrt {11} } {2} \: or \: x = \frac{ 5 }{2} + \frac{\sqrt {11} } {2} [/tex]

EXPLANATION

The given quadratic equation is:

[tex] 2{x}^{2} - 10x + 7 = 0[/tex]

Comparing this equation to

[tex] a{x}^{2} + bx + c = 0[/tex]

we have

a=2, b=-10 and c=7.

The solution is given by the quadratic formula;

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

We plug in the values to get,

[tex]x = \frac{ - - 10 \pm \sqrt{ {( - 10)}^{2} - 4(2)(7) } }{2(2)} [/tex]

This implies that

[tex]x = \frac{ 10 \pm \sqrt{ {100} - 56 } }{4} [/tex]

[tex]x = \frac{ 10 \pm \sqrt {44 } }{4} [/tex]

[tex]x = \frac{ 10 \pm 2\sqrt {11 } }{4} [/tex]

[tex]x = \frac{ 5 \pm \sqrt {11 } }{2}[/tex]

[tex]x = \frac{ 5 }{2} - \frac{\sqrt {11} } {2} \: or \: x = \frac{ 5 }{2} + \frac{\sqrt {11} } {2} [/tex]

Answer:

The area of the walls is [tex]2,160\ ft^{2}[/tex]

Step-by-step explanation:

we know that

The area of the walls is equal to the perimeter of the conference room multiplied by the height of the ceiling

so

[tex]A=2[40+50](12)=2,160\ ft^{2}[/tex]

Answer:

A = (1/2)(16 cm)(12 cm) = 96 cm^2

Step-by-step explanation:

Because this is a right triangle, we know that the leg lengths are 12 cm and 16 cm respectively, and that these legs are at right angles to one another.

We can assume that the base of this triangle is 16 cm and that the height is 12 cm.  Then, according to the area-of-a-triangle formula, A = (1/2)(base)(height), the area of this particular triangle is

A = (1/2)(16 cm)(12 cm) = 96 cm^2.

Answer:

A

Step-by-step explanation:

The hypotenuse is the longest side of a triangle, meaning the hypotenuse is 20 cm. The equation for the area of a triangle is base multiplied by height multiplied by one half. (1/2bh) 12 × 16 = 192. 192 × 1/2 = 96. The area of this triangle is 96 cm^2.

Final answer:

The sum 42 + 24 can be expressed as 24 + 42 using the commutative property of addition, or by decomposing into tens and units for easier mental calculation.

Explanation:

The student is asking for another way to express the sum 42 + 24. One way to approach this is by performing a common mathematical technique known as commutation (or the commutative property of addition), which states that numbers can be added in any order and the sum will remain the same.

So, another way to express 42 + 24 would be 24 + 42. You can also decompose the numbers into tens and units to simplify mental calculation: (40 + 20) + (2 + 4) = 60 + 6 = 66. This demonstrates that there are multiple ways to approach addition, making it easier to perform in my head. Thus, we affirm that mathematics indeed offers many paths to the same answer.

Answer:

110

Step-by-step explanation:

2=80 and 3=30

2+3=ac=110

Answer:

Option B. 110°

Step-by-step explanation:

In the given circle m ∠1 = 100°

m BC = 30°

Then we have to find the measure of m AC

Since ∠1 = 100°

and ∠1 + ∠2 = 180° [supplementary angles]

100 + ∠2 = 180°

∠2 = 180° - 100°

∠2 = 80°

Now we know ∠3 = 15°

and m AC = ∠2 + ∠3

m AC = 80 + 30 = 110°

Therefore, Option B. 110° will be he answer.

Answer:

17.6 ounces per 500 g

Step-by-step explanation:

Knowing one ounce equals 28.34 g, all we have to do is divide half a kilo (500 g) by the equivalent of an ounce to get the number of ounces in a kg.  So,

O = 500 g / 28.34g/ounce = 17.64 ounces

We round that to the nearest tenth... to get 17.6 ounces per 500 g

Converting between metric and imperial/US system is always complicated.

Answer:

0.5 kilograms (kg) is equal to 17.6 ounces

Step-by-step explanation:

We have

                    1 kg = 35.274 ounces

                   0.5 kg = 0.5 x 35.274 = 17.637 ounces

Rounding to nearest tenth

              0.5 kg = 17.637 ounces   = 17.64 ounces = 17.6 ounces

So we have 0.5 kilograms (kg) is equal to 17.6 ounces

Final answer:

To find the simplified form of the quadratic equation at² + bt + c = 0 with constants a = 4.90, b = -14.3, and c = -20.0, we use the quadratic formula to calculate the discriminant and then the two possible solutions for t.

Explanation:

The original expression provided: [tex](m^3/4c^5)-4[/tex] does not match the information given about quadratic equations. Instead, here's how we would solve a quadratic equation using the provided constants:

A quadratic equation is of the form at² + bt + c = 0. Given constants a = 4.90, b = -14.3, and c = -20.0, the solutions to the quadratic equation can be found using the quadratic formula, which is t = (-b ± √(b²-4ac)) / (2a).

To find the solutions for the given quadratic equation, plug in the values for a, b, and c into the quadratic formula:

Answer:

Third Option

[tex]f(x) = 4x,\ g(x)=\frac{1}{4}x[/tex]

Step-by-step explanation:

For a function f(x) it is satisfied that the range of f(x) is equal to the domain of its inverse function. In the same way the domain of f(x) is equal to the range of its inverse.

Therefore, to verify which pair of functions are inverse to each other, perform the composition of both functions and you must obtain

[tex]f(g(x)) = x[/tex]  and   [tex]g(f(x)) = x[/tex]

For the first option we have:

[tex]f(x) = x,\ g(x)=-x[/tex]

Then

[tex]f(g(x)) = (-x) = -x[/tex]  They are not inverse functions

For the second option we have:

[tex]f(x) = 2x,\ g(x)=-\frac{1}{2}x[/tex]

Then

[tex]f(g(x)) = 2(-\frac{1}{2}x) = -x[/tex]  They are not inverse functions

For the third option we have:

[tex]f(x) = 4x,\ g(x)=\frac{1}{4}x[/tex]

Then

[tex]f(g(x)) = 4(\frac{1}{4}x) = x[/tex]

[tex]g(f(x)) = \frac{1}{4}(4x) = x[/tex] They are inverse functions

For the fourth option we have:

[tex]f(x) = -8x,\ g(x)=8x[/tex]

Then

[tex]f(g(x)) = -8(8x) = -64x[/tex]  They are not inverse functions

In the given geometric series, the common ratio is 5. The value of n, which indicates the term number, is found to be 4 by setting up and solving an equation based on the general formula for the nth term in a geometric series.

The series presented is a geometric series. In a geometric series, each term is multiplied by a common ratio to get the next term. In this case, the common ratio is 5 because each term is obtained by multiplying the previous term by 5.

In a geometric series, the general formula for the nth term is a * r^(n-1), where a is the first term and r is the common ratio. Hence, let's set up the nth term equation and solve for n.

500 = 4 * 5^(n-1)

When we solve the equation, we find that the value of n is 4.

Answer:

(4, 11)

Step-by-step explanation:

Given the 2 equations

y = 5x - 9 → (1)

y = x² - 3x + 7 → (2)

Substitute y = x² - 3x + 7 = 5x - 9 ( subtract 5x - 9 from both sides )

x² - 8x + 16 = 0 ← quadratic equation in standard form

(x - 4)² = 0 ← in factored form as a perfect square, so

x - 4 = 0 ⇒ x = 4

Substitute x = 4 into (1) for corresponding value of y

y = 20 - 9 = 11

Solution (x, y) → (4, 11)

Answer:

The equation would be:

(X+1)^2 + (y-1)^2 = 9

This is the equation of the circle in general form.  

[tex]\[ x^2 + y^2 + 2x - 2y - 7 = 0 \][/tex]

or

[tex]\[ (x + 1)^2 + (y - 1)^2 = 9 \][/tex]

To write the equation of a circle in general form, you start with the standard form of the circle's equation, which is:

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

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

From the information provided:

- The center of the circle is \( (-1, 1) \)

- The radius of the circle is \( 3 \) units

Let's substitute these values into the standard form:

[tex]\[ (x - (-1))^2 + (y - 1)^2 = 3^2 \][/tex]

[tex]\[ (x + 1)^2 + (y - 1)^2 = 9 \][/tex]

Now, to write it in general form, you'll expand the equation and combine like terms:

Step 1: Expand the squares

[tex]\[ (x + 1)^2 = x^2 + 2x(1) + 1^2 \][/tex]

[tex]\[ (y - 1)^2 = y^2 - 2y(1) + 1^2 \][/tex]

Step 2: Write the expanded form

[tex]\[ x^2 + 2x + 1 + y^2 - 2y + 1 = 9 \][/tex]

Step 3: Combine like terms

[tex]\[ x^2 + y^2 + 2x - 2y + 1 + 1 = 9 \][/tex]

Step 4: Move the constant to the right side

[tex]\[ x^2 + y^2 + 2x - 2y = 9 - 2 \][/tex]

Step 5: Final general form

[tex]\[ x^2 + y^2 + 2x - 2y - 7 = 0 \][/tex]

This is the equation of the circle in general form.

answer : (A) q>p , where p= jacks pet is a pig and q= jacks pet cannot fly

The converse of an implication reverses the order of the original statement. Therefore, the converse of 'If Jack’s pet is a pig then Jack’s pet cannot fly' is 'If Jack's pet cannot fly, then Jack's pet is a pig'.

In this problem, we're dealing with a form of logical statement known as an implication, which can be symbolized as p → q. In the original statement, 'If Jack’s pet is a pig (p) then Jack’s pet cannot fly (q)', the implication is that being a pig causes or results in the inability to fly. The converse of an implication reverses the order of the original statement, so 'if q then p'. Therefore, the converse of the given statement would be 'If Jack's pet cannot fly, then Jack's pet is a pig', or symbolically represented as q → p.
