The zeroes of the quadratic equation are -

[tex]\frac{-8-\sqrt{82} }{2}[/tex]  and  [tex]\frac{-8+\sqrt{82} }{2}[/tex].

We have the following quadratic equation -

f(x) = [tex]2x^{2} +16x-9[/tex]

We have to find the zeroes of this quadratic function.

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is [tex]ax^{2} +bx+c[/tex] , where a and b are the coefficients, x is the variable, and c is the constant term.

According to the question, we have a quadratic equation -

f(x) = [tex]2x^{2} +16x-9[/tex]

In order to find its zeroes, we will equate f(x) = 0. Therefore -

[tex]2x^{2} +16x-9 = 0[/tex]

Using the quadratic formula -

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

Where a = 2, b = 16 and c = -9.

Substituting the values, we get -

x = [tex]\frac{-16\pm\sqrt{(16)^2-4(2)(-9)}}{2(2)}[/tex]

x = [tex]\frac{-8\pm\sqrt{82} }{2}[/tex]

Hence, the zeroes of the quadratic equation are -

[tex]\frac{-8-\sqrt{82} }{2}[/tex]  and  [tex]\frac{-8+\sqrt{82} }{2}[/tex].

Answer:

106 slices left

Step-by-step explanation:

To solve this we need to multiply 19 and 6:

19 * 6 = 114

there was 114 slices of pizza

next subtract 114 and 8

114 - 8 = 106

there was 106 slices of pizza left after Miguel ate 8 slices of pizza

Final answer:

After calculating the total slices from 19 pizzas and subtracting the 8 slices consumed by Miguel, there are 106 pizza slices left for the rest of the French Club.

Explanation:

The student asked about the number of pizza slices left after Miguel ate some. To calculate this, we first need to find the total number of slices in 19 pizzas, each cut into 6 slices, and then subtract the 8 slices that Miguel ate.

Calculate the total number of slices: 19 pizzas × 6 slices/pizza = 114 slices.

Subtract the slices Miguel ate: 114 slices - 8 slices = 106 slices.

So, there are 106 pizza slices left for the rest of the French Club.

The graph that best represents the described temperature change is Graph A.

The description provided suggests a graph of temperature change over time.

In the morning, the temperature starts around 50°F, so the initial point on the graph would be at (0, 50). As the day progresses, the temperature rises first slowly and then more quickly, indicating a steeper slope.

After reaching a peak, the temperature stays constant for an hour, suggesting a flat line parallel to the x-axis.

Finally, the temperature drops slowly, indicating a decreasing slope.

Based on this description, Graph A represents the temperature change over the day.

Answer:

[tex]59.19 ft^2[/tex]

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=7.2\ ft[/tex]

[tex]\pi =3.14[/tex]

substitute

[tex]A=(3.14)(7.2)^{2}[/tex]

[tex]A=162.78\ ft^2[/tex]

step 2

we know that

The area of a circle subtends a central angle of 2π radians

so

using proportion

Find out the area of a sector with a central angle of 8 π/11 radians

[tex]\frac{162.78}{2\pi }\frac{ft^2}{rad} =\frac{x}{(8\pi/11)}\frac{ft^2}{rad} \\\\x=162.78(8/11)/2\\\\x=59.19\ ft^2[/tex]

Final answer:

The area of a sector with a central angle of 8π/11 radians and a radius of 7.2 ft, using 3.14 for π, is approximately 78.60 ft² when rounded to the nearest hundredth.

Explanation:

To calculate the area of a sector of a circle, we use the formula ½ θr², where θ is the central angle in radians, and r is the radius of the circle. For a sector with a central angle of ₈π/₁₁ radians and a radius of 7.2 ft, substituting 3.14 for π, we can find the area as follows:

Use the formula: Area = (½)(θ)(r²).

Substitute the given values to get: Area = (½)(₈π/₁₁)(7.2 ft)².

Calculating using 3.14 for π we get: Area = (0.5)*(8*3.14/11)*(7.2 ft)².

Simplify and calculate the result which gives us: Area = 78.5952 ft².

Round the final answer to the nearest hundredth: Area = 78.60 ft².

Answer:

0.54

Step-by-step explanation:

In Probability "OR" means "ADDITION" and "AND" means "MULTIPLICATION"

Here, we want probability of Jack "OR" Red, so we find individual probabilities and then "ADD" them.

There are 26 cards that are RED, half of the deck. So probability of RED CARD is:

P(red) = 26/52 = 1/2

Now, there are 4 Jacks in the whole deck, 2 red Jack and 2 black Jack. We already accounted for the 2 red jacks, so we have 2 black Jacks at hand. So

P(Jack) = 2/52 = 1/26

Now, we add the 2 probabilities:

P(jack or red) = 1/2 + 1/26 = 13/26 + 1/26 = 14/26 = 0.54 (rounded to 2 decimal places)

The only prime number that is a factor of 16 is 2, since 16 is a power of 2 (2⁴).

The student has asked to identify the only prime number that is a factor of 16. To find the factors of 16, we can break it down into its prime factors. The prime factorization of 16 is 2×4×4, which reduces further to 2×2×2×2 or 24. Since the prime factors of 16 are all 2s, the only prime number that is a factor of 16 is 2. It's important to note that a prime number is defined as a number that has exactly two distinct positive divisors: 1 and the number itself. In the case of 16, 2 is the only prime number that fits this definition and is a factor.

Answer:

4 + x = 16

Step-by-step explanation:

In general, if we have an equation that has just one variable, such as x, then "solving the equation" means finding the set of all values that can be substituted for the one variable to produce a valid equation.

Isolate "x" on one side of the algebraic equation by adding the negative number that appears on the same side of the equation as the "x." For example, in the equation "x - 5 = 12", rewrite the equation as "x = 12 + 5" and solve for "x."

Answer:

B = 26.407 degrees

C = 73.593 degrees

c = 30.196 units

Step-by-step explanation:

Use the law of sines

sin(B) / 14 = sin(80) / 31

B = sin-1( sin(80) / 31 x 14)

B = 26.407

C = 180 - 80 - 26.407

C = 73.593

c / sin(73.593) = 31 / sin(80)

c = 31 / sin(80) x sin(73.593)

c = 30.196

Answer:

  232 square feet

Step-by-step explanation:

The outside dimensions of the yard are 26 ft by 36 ft, so its total area is ...

  yard including walk = (26 ft)(36 ft) = 936 ft²

The dimensions of the yard inside the walkway are 22 ft by 32 ft, so that area is ...

  yard not including walk = (22 ft)(32 ft) = 704 ft²

The difference in these areas is the area of the walkway:

  walkway area = (yard including walk) - (yard not including walk)

  = (936 -704) ft² = 232 ft² . . . . area of the walk

_____

Another way to figure this is to consider the length of the centerline of the walkway. That is the perimeter of a rectangle that is 24 ft by 34 ft. The perimeter (centerline length) is 116 ft, and the width of the walk is 2 ft, so its area is ...

Answer:

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

This is only true if it is an isosceles trapezium so B is false.

Final answer:

The false statement is that the perpendicular bisector of the base of any trapezoid is always a line of symmetry. This is incorrect as only isosceles trapezoids, which have two non-parallel sides of equal length, are symmetrical in this way.

Explanation:

The statement that is FALSE is: B) The perpendicular bisector of the base of any trapezoid is always a line of symmetry. This statement is incorrect because a trapezoid, by definition, has only one pair of parallel sides, and not all trapezoids are symmetrical unless specified as an isosceles trapezoid. For instance, in irregular trapezoids where the non-parallel sides are of different lengths, the perpendicular bisector of the base does not act as a line of symmetry.

Moreover, statement C, which is true, specifies the conditions under which the perpendicular bisector of the base can be a line of symmetry - that is, in the case of an isosceles trapezoid. An isosceles trapezoid is specifically designed to be symmetrical along the perpendicular bisector of its bases, given its two non-parallel sides are equal in length, unlike general trapezoids.

Answer: She is earning $15 a week.

Step-by-step explanation:

Since she started with 50 dollars you need to subtract. So 140-50=90. Since she has been saving for 6 weeks, you need to divde, so 90÷6=15.

The two numbers are -20 and -82. By creating two equations x + y = -102 and x = y - 62, substitute for x in the first equation and solve for y, then substitute y back into the second equation to solve for x.

To solve the problem, you can create two equations using the given information.

You can now substitute the equation from step 2 into equation 1:

(y - 62) + y = -102.

Combine like terms:

2y - 62 = -102.

Then add 62 to both sides of the equation:

2y = -40.

Finally, divide both sides by 2:

y = -20.

Substitute y = -20 back into x = y - 62:

x = -20 - 62 = -82.

Answer:

120 ounces

Step-by-step explanation:

Answer:

a)  About 46.3 hours

b) About $1036.80

Step-by-step explanation:

a)

Break even means to make enough to cover her costs.

Given her cost is 1000, we need to find how many hours she will need to cover this up.

In 1 minute, she can type 90 words, that would pay her:

0.004 per word for 90 words = 0.004 * 90 = $0.36 per minute

Susan makes $0.36 per minute, so the amount of time (in minutes) it will take her to make $1000, is:

1000/0.36 = 2777.78 minutes

Converting that to hours, we divide by 60,

2777.78/60 = 46.3 hours

b)

4 hours per day for 3 days = 4 * 3 = 12 hours (per week)

Let there be 4 weeks in a month, so

12 hours per week * 4 = 48 hours per month

She will work 48 hours per month.

Given 90 words per minute, in 1 hour, she can type:

60 minutes * 90 = 5400 words per hour

In 48 hours, she can type:

5400 words per hour * 48 hours = 259,200 words

That would pay her:

0.004 per word for 259,200 words = 0.004 * 259,200 = $1036.80
