Answer: OPTION C

Step-by-step explanation:

By definition, the roots of the quadratic function are the interceptions of the parabol with the x-axis.

As you can see in the graph, the parabola intersects the x-axis at:

[tex]x=-5\\x=1[/tex]

Then these are the roots.

Therefore, this means that:

[tex]x=-5\\x+5=0\\\\x=1\\x-1=0[/tex]

So, the factorization is the following:

[tex](x+5)(x-1)=0[/tex]

ANSWER

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

EXPLANATION

From the graph, the x-intercepts are

[tex]x = 1[/tex]

and

[tex]x = - 5[/tex]

This implies that (x-1) and (x+5) are factors of the function represented by the graph.

Therefore we factor the function as

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

The correct choice is C.

Answer:

[tex]\large\boxed{RT=\sqrt{165}}[/tex]

Step-by-step explanation:

PT = NT. Therefore we have the equation:

[tex]4x-17=x+10[/tex]       add 17 to both sides

[tex]4x=x+27[/tex]          subtract 4x from both sides

[tex]3x=27[/tex]         divide both sides by 3

[tex]x=9[/tex]

Therefore

[tex]NT=4(9)-17=36-17=19[/tex]

Use the Pythagorean theorem:

[tex]RT^2+RN^2=NT^2[/tex]

Substitute RN = 14 and NT = 19:

[tex]RT^2+14^2=19^2[/tex]

[tex]RT^2+196=361[/tex]           subtract 196 from both sides

[tex]RT^2=165\to RT=\sqrt{165}[/tex]

Answer:

diameter ≈ 11 feet

Step-by-step explanation:

The area (A) of a circle is calculated using the formula

A = πr² ← r is the radius

To find r divide both sides of the equation by π

r² = [tex]\frac{A}{\pi }[/tex] = [tex]\frac{95.03}{\pi }[/tex]

Take the square root of both sides

r = [tex]\sqrt{\frac{95.03}{\pi } }[/tex] ≈ 5.5 feet

Diameter = 2r = 2 × 5.5 = 11 feet

A circle is a curve sketched out by a point moving in a plane. The diameter of the circle whose area is 950.3 square feet is 11 feet.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

As it is given that the area of the circle is 95.03 square feet. Therefore, if we apply the area of the circle, we will get,

[tex]\text{Area of the circle} = \pi r^2[/tex]

where r is the radius of the circle,

[tex]\rm 95.03 = \pi r^2\\\\r = \sqrt{\dfrac{95.03}{\pi}}\\\\r = 5.4999 \approx \rm 5.5\ feet[/tex]

The radius of the circle is half the diameter of the circle, therefore, the diameter of the circle,

[tex]\rm Radius = \dfrac{Diameter}{2}\\\\5.5 \times 2 = Diameter\\\\Diameter = 11\ feet[/tex]

Thus, the diameter of the circle whose area is 950.3 square feet is 11 feet.

Answer:

y = 9x - 5

Step-by-step explanation:

Any line parallel to the given line y = 9x must also have the slope 9.

Substitute the known values (m = 9, h = 0, k = -5) into the point-slope equation of a straight line:

y - (-5) = 9(x - 0)

Final answer:

The expression 5 Square root of 1215^x can be simplified to 5^(1+x/2) × 3^(5x/2) by factoring 1215 and applying exponent rules.

Explanation:

To find what is equivalent to 5 Square root of 1215^x, we need to simplify the radical expression and apply exponent rules. The number 1215 can be factored into 3^5 × 5. Therefore, the square root of 1215 is the square root of each factor raised to the power of x. We know that the square root of a number can be expressed as the number raised to the power of 1/2. So 1215 raised to the power x can be expressed as (3^5 × 5)^x, and taking the square root gives us (3^5 × 5)^(x/2).

Applying exponent rules, like multiplying powers when the same base is raised to two different exponents (as per Eq. A.8 and what we know from Integer Powers), we can simplify the expression further. Our expression of 5 times the square root of 1215 raised to the power x becomes 5 × 3^(5x/2) × 5^(x/2).

We can then combine the coefficients (5 × 5^(x/2)) which simplifies to 5^(1+x/2). Our final expression of the original problem then becomes 5^(1+x/2) × 3^(5x/2), which is the simplified version of the original expression.

Answer:

125%

Step-by-step explanation:

Lopez made more than the required minimum. So, his percentage will be over 100, for sure. But how much?

This question is essentially asking "60 is what percent of 48"?

We can translate this into:

60 = P * 48

Note: is means "=" and of means "*"

Solving for p:

[tex]60=P*48\\P=\frac{60}{48}\\P=1.25[/tex]

In percentage it is 1.25 * 100 = 125%

Final answer:

Mr. Lopez made 125% of the minimum required number of circuit boards on Wednesday, by dividing the 60 circuit boards he made by the minimum of 48 and then multiplying by 100.

Explanation:

The question asks how to calculate the percentage of the minimum amount of circuit boards Mr. Lopez made on Wednesday. To find this percentage, we divide the number of circuit boards made by Mr. Lopez by the minimum required number and then multiply by 100 to convert it into a percent.

Step-by-Step Solution:

Mr. Lopez made 60 circuit boards on Wednesday.

The minimum requirement is 48 circuit boards per day.

To find the percentage, use the formula: (Actual amount / Minimum requirement) x 100%.

So, the calculation would be: (60 / 48) x 100% = 125%.

Therefore, Mr. Lopez made 125% of the minimum required number of circuit boards on Wednesday.

To multiply mixed numbers, convert them into improper fractions, multiply the numerators and denominators separately, and simplify the resulting fraction.

Explanation:

To multiply mixed numbers, we first convert them into improper fractions. Then, we multiply the numerators and denominators separately and simplify the resulting fraction if possible.

In this case, (2 4/5) can be written as 14/5 and (-5 2/3) can be written as -17/3. Therefore, (2 4/5) (-5 2/3) can be simplified to (-14/5) * (-17/3).

To multiply fractions, we multiply the numerators and denominators together. So, (-14/5) * (-17/3) = (14 * 17) / (5 * 3) = 238/15 = 15 13/15.

Final answer:

To find the area of a circle with a circumference of 53.41 inches, calculate the radius using r = C / (2π) and then find the area using A = πr². The area is approximately 226.795 square inches.

Explanation:

To find the area of a circle given its circumference, you can use the formula for the circumference, C = 2πr, where C is the circumference and r is the radius. From there, you can derive the radius and then calculate the area using the formula A = πr². Given that the circumference is 53.41 inches, we first find the radius (r).

The formula for circumference (C) simplifies to r = C / (2π). Thus, r = 53.41 inches / (2×3.14), which gives us r = 53.41 / 6.28 = approximately 8.5 inches. Now that we have the radius, we can plug it into the area formula A = πr². Using the given radius, the area A equals 3.14×8.5² inches², which is about 3.14×72.25 inches² = 226.795 inches² (rounded to three significant figures).

Answer:

Reference angle: [tex]\frac{\pi}{2}[/tex]

[tex]tan(\theta)=tan(\frac{3\pi}{2})[/tex] is not defined.

Step-by-step explanation:

The angle [tex]\theta[/tex] goes from the positive x-axis to the negative y-axis.

Therefore the reference angle can be calculated as following:

[tex]\frac{3\pi}{2}-\pi=\frac{\pi}{2}[/tex]

 We know that [tex]tan(\theta)[/tex]is:

[tex]tan(\theta)=\frac{sin(\theta)}{cos(\theta)}[/tex]

If [tex]\theta=\frac{3\pi}{2}[/tex] then [tex]cos(\frac{3\pi}{2})=0[/tex], therefore [tex]tan(\frac{3\pi}{2})[/tex] is not defined, because the division by 0 is not defined.

Answer:

I know for a fact that the reference angle for 3pi/2 is pi/2 so the first one is A, and if I'm not mistaken, the second one should be undefined.

Step-by-step explanation:

the fraction is boys over total in class, that is

fraction of boys = [tex]\frac{8}{24}[/tex] ( divide top/bottom by 8 )

fraction of boys = [tex]\frac{1}{3}[/tex] ← in simplest form

(b)

The number of girls in class = 24 - 8 = 16

fraction of girls = [tex]\frac{16}{24}[/tex] ( divide top/bottom by 8 )

fraction of girls = [tex]\frac{2}{3}[/tex] ← in simplest form

The number of boys is 1/3

The number of girls is 2/3

Total no of students = 24

No of boys in the class is 8

So in fraction form

Boys = 8 out of 24 which is 8/24 or simply 1/3

Now

For girls

no of girls will be Total students - boys students

Number of girls students = 24 - 8 = 16

In fraction form we can write 16/24 or simply 2/3
