-3, -1, and 0.

Step-by-step explanation:

Anything from -4 and lower makes it false. So, -8 would have to be unselected. And -3 would have to be selected.

Answer: 2.1 Find the Vertex of y = x2-17x-50

Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 1 , is positive (greater than zero).

Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.

Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.

For any parabola,Ax2+Bx+C,the x -coordinate of the vertex is given by -B/(2A) . In our case the x coordinate is 8.5000

Plugging into the parabola formula 8.5000 for x we can calculate the y -coordinate :

y = 1.0 * 8.50 * 8.50 - 17.0 * 8.50 - 50.0

or y = -122.250

Firlakuza [10]

Answer:

She needs to save $500 each month over the next 2 years to fulfill her first year of tuition.

Step-by-step explanation:

Consider the provided information.

She needs $48,000 per year for tuition.

The university offered financial aid that covers 50% of her tuition expenses.

It means she needs to pay only 50% of $48,000 per year for the tuition fee.

$50\% \times 48,000=\frac{50}{100}\times48,000$

$=24,000$

Now she needs $24,000 for tuition expenses.

Her parents contribute $10,000 for tuition each year and she receives a local scholarship for $2,000.

Now, for the first year of tuition, she needs=$24,000-$10,000-$2000

=$12,000

In 2 years there are 24 months, which means she needs to save $12,000 in 24 months.

Amount she needs to save each month = $\dfrac{\$12000}{24}=\$500$

Hence, she needs to save $500 each month over the next 2 years to fulfill her first year of tuition.

In a circle with a radius of 12.6 ft, an arc is intercepted by a central angle of 2 radians

Gennadij [26K]

Question:

In a circle with a radius of 12.6 ft, an arc is intercepted by a central angle of 2π/7 radians.

What is the arc length?

Use 3.14 for π and round your final answer to the nearest hundredth.

Enter your answer as a decimal in the box.

Answer:

<h3>Arc length is 11.30 feet</h3>

Solution:

Given that,

Radius of circle = 12.6 feet

Central angle = $\frac{2 \pi }{7}$ radians

To find: Arc length

The arc length of a circle of radius "r" when central angle given in radians is:

$s = r \times \theta$

Where,

s is the arc length

r is the radius

$\theta$ is the central angle in radians

Substituting the values we get,

$s = 12.6 \times \frac{2 \times \pi }{7}\\\\s = 12.6 \times \frac{2 \times 3.14 }{7}\\\\x = 11.304 \approx 11.30$

Thus, arc length is 11.30 feet
