An object is launched vertically at a velocity of 160 feet per second from the top of a building 100 feet above the ground. Use the model h=-16t^2+vt+c where h is the height of the object at any time t, c is the initial height, in feet, of the object, t is the time in seconds and v is the velocity of the object.
How long will it take the object to reach the maximum height, and what is the maximum height?(Round to the nearest whole number)
Answers
Answer:
The question let's us set up the equation
Hope it helps!
Step-by-step explanation:
160= 16t^2+96t+16 and we just solve for t to get t= 3(sqrt 2 - 1) and -3(sqrt 2 - 1).

QUESTION 27
A research survey of 4750 adults found that 4275 had purchased something online of these shoppers, 789 are weekly online shoppers.
Construct a 99% Confidence interval estimate of the population proportion of adults who had purchased something online
A The Point Estimate equals 50.60
(Round to 1 decimal place)
B. The Standard Error equals 1243
(Round to 4 decimal places)
The Critical Value equals
(Round to 2 decimal places)
(Round to 4 decimal places)
D. The Margin of Error equals
and
E. & F. We are 99% confident the true proportion of adults who purchased something online is between
(Round to 4 decimal places)
Answers
Using the z-distribution, it is found that characteristics are:
a) 0.2
b) 0.0058
c) z = 2.575
d) 0.0149
e) (0.1851, 0.2149).
f) We are 99% confident the true proportion of adults who purchased something online is between 0.1851 and 0.2149.
Item a:
The point estimate is the sample proportion, hence:
[tex]\pi = \frac{789}{4750} = 0.2[/tex]
Item b:
The standard error is:
[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.2(0.8)}{4750}} = 0.0058[/tex]
Item c:
99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so [tex]z = 2.575[/tex].
Item d:
The margin of error is:
[tex]M = zs = 2.575(0.0058) = 0.0149[/tex]
Item e:
The interval is the point estimate plus/minus the margin of error, hence
[tex]\pi - M = 0.2 - 0.0149 = 0.1851[/tex]
[tex]\pi + M = 0.2 + 0.0149 = 0.2149[/tex]
The 99% confidence interval estimate of the population proportion of adults who had purchased something online is (0.1851, 0.2149).
Item f:
We are 99% confident the true proportion of adults who purchased something online is between 0.1851 and 0.2149.

a. What is mZw?
b. What is mZz?
Answers
z= 55
for w take 90+35 then your answer minus 180 which would equal 55. w and y are vertical angles therefore you can add 55+70 and get 125, 180-125= 55, so 55 would be the answer for both w and z

Use the INCLUSIVE definition of a trapezoid to identify the TRUE statement. Select all that apply.
No parallelograms are trapezoids.
All parallelograms are trapezoids.
No trapezoids are parallelograms
Trapezoids do not have any parallel sides
A trapezoid has at least one pair of parallel sides.
(I’ll mark brainlist of you wrote down, not link’)
Answers
Answer:
All parallelograms are trapezoids.
No trapezoids are parallelograms.
A trapezoid has at least one pair of parallel sides
Step-by-step explanation:
1. Since a parallelogram has two pairs of parallel sides then it has at least one pair of parallel sides. Therefore, all parallelograms are also classified as trapezoids.
2. Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram.
3. A trapezoid has one pair of parallel sides.
(I can't put a picture, but I would if I could)
The statement "All parallelograms are trapezoids", statement "No trapezoids are parallelograms" and statement "A trapezoid has at least one pair of parallel sides" are correct.
What is a trapezoid?It is defined as the quadrilateral having four sides in which two sides are parallel to each other, it is a 2-dimensional geometry.
A parallelogram has at least one pair of parallel sides, since it has two pairs of parallel sides. As a result, all parallelograms are considered trapezoids.
Parallelograms have two pairs of parallel sides, whereas trapezoids have only one pair. A parallelogram can never be a trapezoid.
Thus, the statement "All parallelograms are trapezoids", statement "No trapezoids are parallelograms" and statement "A trapezoid has at least one pair of parallel sides" are correct.

Find the distance CD rounded
to the nearest tenth.
C = (-5,4) D = (5,8)
CD = [?]
HINT: Use the distance formula:
d = V(x2 - xı)2 + (y2 - yı)2
Answers
Answer:
The distance is of 10.8 units.
Step-by-step explanation:
Distance between two points:
Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
In this question:
C(-5,4) and D(5,8). So
[tex]D = \sqrt{(5-(-5))^2 + (8-4)^2} = \sqrt{10^2 + 4^2} = 10.8[/tex]
The distance is of 10.8 units.
