Answer:
8 seconds
Step-by-step explanation:
Given :
h(t) = -16t2 + initial height
Initial height = 1024 feets
By the time it hits the ground, h(t) = 0
Equation becomes :
0 = - 16t² + 1024
Solve for t
-16t² = 1024
t² = 1024 / -16
t² = 64
t = √64
t = 8
Hence, it will take 8 seconds

1. If A is an invertible matrix, then what is det(A-1) equal to?
a) 0
b) det (A)
c) 1/det(A)
d) 1
Answer:
b) det (A)
Step-by-step explanation:
The determinant of the inverse of an invertible matrix is the inverse of the determinant: det(A-1) = 1 / det(A) [6.2. 6, page 265]. Similar matrices have the same determinant; that is, if S is invertible and of the same size as A then det(S A S-1) = det(A).

58 Select the correct answer. An investment banking house conducted a survey to determine how two of its proposed investment plans for three different age categories are used. This table shows the responses they received. Plan l Plan II Neither 19 14 17 Ages 26-35 Ages 36-45 Ages 46-55 14 28 8 00 27 21 2 What percentage of people preferring plan I are from the 36-45 age group, and what percentage of people from the 46-55 age group prefer plan II? Round your answers to the nearest whole number. OA 2396 of people who prefer plan I are from the 36-45 age group, and 42% of people from the 46-55 age group prefer plan II . O B. 28% of people who prefer plan I are from the 36-45 age group, and 42% of people from the 46-55 age group prefer plan II. 2396 of people who prefer plan I are from the 36-45 age group, and 33% of people from the 46-55 age group prefer plan II. 28% of people who prefer plan I are from the 36-45 age group, and 33% of people from the 46-55 age group prefer plan II. OD es reserved
Answer:
23% of people who prefer plan I are from the 36–45 age group, and 42% of people from the 46–55 age group prefer plan II.
Step-by-step explanation:
___________Plan I___ Plan II ___Neither
Ages 26–35__ 19_____ 14_______ 17
Ages 36–45__ 14 _____28_______ 8
Ages 46–55__ 27 _____21_______ 2
Total Number who prefer plan 1 = (19 + 14 + 27) = 60
Number in the 36 - 45 age group = 14
Percentage = 14 / 60 = 0.2333 = 23%
Number of people in the 46-55 age group = (27 + 21 + 2) = 50
Number on the age group who prefer plan II = 21
Percentage = 21 / 50 = 0.42 = 0.42 * 100 = 42%
Plot these numbers on the number line:
V2, V5, 3v8, v9, v15, 3v25
Put these numbers in smallest to largest
3.07, 3.7, 3.77, 7.3, 7.33
A game has 50 cards with 10 each numbered 1 to 5,and a player must draw a 2 or a 3 to move out of the "start" position.
Answer:
The question isn't complete, so I will assume that we want to find the probability of moving out of the start position.
First, we know that there is a total of 50 cards.
of these 50 cards, we have:
10 with the number 1
10 with the number 2
10 with the number 3
10 with the number 4
10 with the number 5
To move out of the starting position, we need to draw a 2 or a 3.
And we have 10 of each, then there are 20 cards that allow us to move out of the start position.
The probability of moving out of the starting position in the first draw, is equal to the quotient between the number of cards that allow us to move out of the starting position (20) and the total number of cards (50), this is:
P = 20/50 = 2/5 = 0.4
Find the missing side of the triangle.

A box contains 20balls,x of which are white.if the probability of selecting a non white ball at random is 3/5.find the value of x
Answer:
8
Step-by-step explanation:
So there are 20 balls.
3/5 of them are NOT white.
This means 2/5 of them ARE white.
So knowing this, lets find the number of white balls(x).
To do this, lets multiply the 20 total balls by the 2/5 of them that are white:
20/1*2/5
=
40/5
=
8
So we know that 8 of the balls are white!
Hope this helps! :)
On his way to a job site, Spencer stops to buy bags of concrete mix. Each bag weighs 60 pounds. Spencer’s truck can carry at most 1,700 pounds, and he already has 320 pounds of tools and other equipment in his truck. What are the possible numbers of bags of concrete mix Spencer can buy?
Answer:
28 bags but see below
Step-by-step explanation:
Start by subtracting 320 from 1700
1700 - 320 = 1680
Now he can buy any number of bags as long as he doesn't go over 1680 pounds. Let's see what that means
1680 / 60 = 28 bags of cement.
The answer to the math problem is 28 bags.
In real life, you likely want to trim it that close. What if you hit a bump. That would be very hard on the springs. I'd drop it down to 26 bags if I was actually transporting concreate mix.
He could by any number of bags between 1 and 28 in a math class and a few less in actual practice.

There are 0 solutions because the lines will never intersect (which is due to their slopes being the same).
Step-by-step explanation:
Because we don't have any numbers we're supposed to esitmate, but the important thing to realize is that the slopes are identical
so let's say our equations are
x+1
x-5
2.)
There are 0 solutions because the lines will never intersect (because their slopes are the same)
Answer:
see explanation
Step-by-step explanation:
The solution to a system of equations given graphically is at the point of intersection of the 2 lines.
Therefore if the lines are parallel, they never intersect and hence there is no solution.
The lines given appear to be parallel and so there is no solution.

Find KL pls fast correct answer
Answer:
14Step-by-step explanation:
According to intersecting secants theorem:
KL*JL = ML²Substitute values and solve for x:
(x - 1)(x - 1 + 7) = 12²(x - 1)(x + 6) = 144x² - 5x - 6 = 144x² - 5x - 150 = 0x² - 15x + 10x - 150 = 0x(x - 15) + 10(x - 15) = 0(x - 15)(x + 10) = 0x = 15x = -10 (ignored as negative)Find the value of Kl
