An object is launched on the moon at 16 feet per second (f/s) from a 1152-foot tall tower. The equation for the object's height s at time t seconds after launch is
s(t) = -16t^2 + 16t + 1152, where s is in feet. When does the object strike the moon’s surface and why?
Answer:
0.5seconds later
Step-by-step explanation:
Given the height modeled by the equation:
s(t) = -16t^2 + 16t + 1152
The velocity of the object at the moon surface is zero
ds(t)/dt = 0
ds(t)/dt = -32t + 16
0 = -32t + 16
32 t = 16
t = 16/32
t = 1/2
t = 0.5seconds
Hence the object strikes the moon surface 0.5seconds later
An elevator is traveling underground at a constant rate. The equation y=−2x−10 can be used to represent this situation, where y is the position of the elevator underground in feet and x is the number of seconds the elevator has been traveling.
Which statement best describes the position of the elevator, given this equation?
(a)From a starting position of 2 feet underground, the elevator is descending 10 feet per second.
(b)From a starting position of 10 feet underground, the elevator is ascending 2 feet per second.
(c)From a starting position of 10 feet underground, the elevator is descending 2 feet per second.
(d)From a starting position of 2 feet underground, the elevator is ascending 10 feet per second.

What is the measure of AC⏜?
Step-by-step explanation:
Angle at Center = 2 * Angle at Circumference
Let O be the center of the circle.
By using segment AC,
Angle AOC = 2 * Angle ABC = 2 * 75° = 150°.
Therefore the measure of arc AC is 150°.

What is the coefficient of the third term?
(3x + 2)(7x - 8)
Answer:
Step-by-step explanation:
if you multiply the polynomials
(3x+2)(7x-8)=21x^2-24x+14x-16=21x^2-10x-16
coefficient of the third term -16
(3x + 2)(7x - 8)
21x^2 - 24x + 14x -16
21x^2 -10x - 16
The power descending order is 2, 1 and 0.
You see, -16 = -16x^0. As you know, x^0 = 1.
So, the coefficient of the third terms is -16.

Given that P(x)=x^5-8x^3-x^2+2, what is the remainder when it is divided by x-5?
Answer:
2102
Step-by-step explanation:
The polynomial function P(x)=x^5-8x^3-x^2+2, if it is divided by x-5, first we need to get x from the divisor as shown
since d(x) = x-5
x-5 = 0
x = 5
Substitute x = 5 into the expression to get the remainder
P(x)=x^5-8x^3-x^2+2
P(5)=(5)^5-8(5)^3-(5)^2+2
P(5) = 3125-1000-25+2
p(5) = 2100+2
P(5) = 2102
Hence the remainder is 2102
Which of the following is the best definition of a statistical population?
a. The distribution of all possible values that can be assumed by some statistic, computed from samples of different sizes randomly drawn from different populations.
b. Distribution of some characteristic based on individual observations – for each individual unit we measure the characteristic and then look at the distribution of all of these values.
c. The distribution of all possible values that can be assumed by some statistic, computed from samples of the same size randomly drawn from the same population.
d. The distribution of all possible values that can be assumed by some parameter, computed from a single sample randomly drawn from some population.
c. The distribution of all possible values that can be assumed by some statistic, computed from samples of the same size randomly drawn from the same population.
c. The distribution of all possible values that can be assumed by some statistic, computed from samples of the same size randomly drawn from the same population.
What is the statistical population?A population is the group of people from which a statistical sample is taken in statistics. Therefore, a population is any collection of people who have something in common. A statistically significant portion of a population, rather than the full population, may also be referred to as a sample.
When surveying a big number of people, it is just impracticable to examine everyone who fits the description you are looking at using a population parameter. It is often easier to study a smaller sample of participants, but by applying inferential statistics, it is possible to get a good approximation of the population parameter.
thus, statistical population is the distribution of all of the statistics calculated from all possible samples of the same size.
Therefore, The statistical population, which is calculated from samples of the same size randomly selected from the same population, is the distribution of all potential values that can be assumed by a statistic.

What is the slope in slope-intercept form for these graphs?
Answer:
Step-by-step explanation:
for this graph find rise over run , and where the line crosses they y axis.. sooo ..
it crosses at -2 and the slope is rise over run or y/x and I can see by the graph that the line goes up 1 when it goes over 1... so the slope is +1
sooo...
use the slope intercept form y = mx + b
y = 1x + (-2)
y = x - 2 :)

What is the width of Averi's area model? (See picture)
Answer:
Width = x² + 5x - 4
Step-by-step explanation:
By the definition of an area model,
Area = Width × greatest common factor
Since, Area = 4x² + 20x - 16
And greatest common factor = 4
4x² + 20x - 16 = 4(Width)
By dividing both the sides of the equation by 4,
[tex]\frac{4x^2+20x-16}{4}=\frac{4(\text{Width})}{4}[/tex]
x² + 5x - 4 = Width
Therefore, width = (x² + 5x - 4) will be he answer.
