Answer: The height of the rocket after 9 seconds is 2068.1 meters.
The height of the rocket when it initially launched is 269 meters.
Step-by-step explanation:
Given, NASA launches a rocket at [tex]t=0[/tex] seconds.
Its height, in meters above sea-level, in terms of time is given by [tex]h=-4.9t^2+244t+269.[/tex]
To find, the height of the rocket after 9 seconds put t=9, we get
[tex]h=-4.9(9)^2+244(9)+269\\\\=-4.9(81)+2196+269\\\\=-396.9+2465\\\\=2068.1[/tex]
Hence, the height of the rocket after 9 seconds is 2068.1 meters.
To find, the height of the rocket when it initially launched put t=0, we get
[tex]h=-4.9(0)^2+244(0)+269\\\\=0+0+269\\\\=269[/tex]
Hence, the height of the rocket when it initially launched is 269 meters.

f(x)=5x-3
f(x)=5(5)-3
f(x)=25-3
f(x)=22
Answer:
[tex]f(5)=22[/tex]
Step-by-step explanation:
since the function is f(x), then you would plug in the 5 since that is x value that is being given then it would be [tex]f(5)=5(5)-3[/tex]. from there multiply 5 and 5 to get 25 then subtract 3 to get 22.
Use elimination to solve the system of equation
4x+y=-2
3x+2y=6
Answer: x= -2,y=6
Step-by-step explanation:
4x+y= -2......equation 1
3x+2y=6.....equ2
Y= -2-4x........equation 3
Substitute equation 3 into 2
3x+2(-2-4x)=6
Open the bracket
3x+(-4-8x)=6
3x-4-8x=6
3x-8x=6+4
-5x=10
X= 10/-5
X= -2
Substitute for x in equation 1
4x+y= -2
4(-2)+y= -2
-8+y= -2
Y= -2+8
Y=6
Therefore, x= -2 & y=6

Answer: The answer should be 6
Step-by-step explanation:
Round 56,291.8 to the nearest thousand.
Answer:
56,000.0
Step-by-step explanation:
The number 6 is in the nearest thousand. To round, you look at the number in front of the number you are trying to round and decide if that number is higher or lower than five. If the number is higher than 5, round up to the next highest number. If the number is lower than 5, the number stays the same.
Final answer:
To round 56,291.8 to the nearest thousand, observe the hundreds digit; it's 2, less than 5, so we keep 56,000 and replace subsequent digits with zeros, giving a rounded figure of 56,000.
Explanation:
To round 56,291.8 to the nearest thousand, we need to look at the hundreds place, which is 2 in this case. Since this is less than 5, we don't round up the thousands place. Therefore, we keep the number 56,000 as it is without increasing the thousand's value. However, since we are rounding to the nearest thousand, we replace the hundreds, tens, ones, and decimal places with zeros, resulting in the final rounded number being 56,000.

Which equation represents the line that passes through the points (-5,2) and (9,0)
Final answer:
To find the equation of the line passing through two given points, we can use the slope-intercept form of a line. The equation of the line passing through (-5,2) and (9,0) is y = -1/7x + 9/7.
Explanation:
To find the equation of the line that passes through the points (-5,2) and (9,0), we can use the slope-intercept form of a line, y = mx + b. First, we need to find the slope (m) of the line. The slope is given by the formula m = (y2 - y1)/(x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. Plugging in the values, m = (0 - 2)/(9 - (-5)) = -2/14 = -1/7.
Next, we can choose one of the points and plug in its coordinates along with the slope into the equation y = mx + b to solve for b. Let's choose the point (-5,2): 2 = (-1/7)(-5) + b. Simplifying the equation, 2 = 5/7 + b. Subtracting 5/7 from both sides, 2 - 5/7 = b. Getting a common denominator, 14/7 - 5/7 = b. So, b = 9/7.
Finally, we can substitute the values of m and b into the equation y = mx + b to get the equation of the line: y = -1/7x + 9/7.
A construction manager weighs a bundle of 9 identical bricks and a 7 pound concrete block. The bundle weighs 30 pounds.
Answer:
30 = 9x + 7
Step-by-step explanation:
The total weight of the bundle = 30 pounds
The weight of the bricks = x pounds
But he carried 9 bricks = 9x pounds
He also carried additional 7 pounds of concrete block.
An equation to show the total weight he carried is
30 pounds = (9x + 7) pounds
Since 9x represents the total weight of the bricks he carried
7 represents the weight of the concrete block
And 30 pounds represents the total weight of everything he carried.

A rectangular box has a length of 8 feet and a width of 2 feet. The length of the three-dimensional diagonal is 10 feet. What is the height of the box?
Answer:
The answer is 4√2 ft i.e (5.66ft)
Step-by-step explanation:
The length, width and height of a rectangular box are all perpendicular.
This means the length of the diagonal is the Pythagorean distance of the three sides.
So, square of diagonal = L^2 + W^2 + H^2
So,
100 = 64 + 4 + H^2
H^2 = 100 - 68 = 32
H = √32 = 4√2 = 5.66ft

RECTANGLE IS 7cm LONGER
THAN THE WIDTH. FIND THE
DIMENSIONS OF THE RECTANGLE.
The length of rectangle is 105 cm and width is 98 cm.
Step-by-step explanation:
Given,
Perimeter of rectangle = 406 cm
Let,
w be the width of rectangle
Length of rectangle = w+7
We know that
Perimeter of rectangle = 2(Length + Width)
[tex]406 = 2(w+7+w)\\406 = 2(2w+7)\\406 = 4w+14\\406-14 = 4w\\392=4w\\4w=392[/tex]
Dividing both sides by 4
[tex]\frac{4w}{4}=\frac{392}{4}\\w=98[/tex]
Width of rectangle = 98 cm
Length of rectangle = 98+7 = 105 cm
The length of rectangle is 105 cm and width is 98 cm.

A bucket contains 50 lottery balls numbered 1-50. One is drawn at random. Find each probability.
P(at least 20 | prime number)
Answer:
For the prime numbers it's 15/50 or 3/10. For it to be at least 20 it's 31/50. For both to happen at the same time it's 7/15.
Step-by-step explanation:
The prime numbers between 1 and 50 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43 and 47.
50-19=31 so 31/50
The probability of drawing a prime number that is at least 20 from a bucket of 50 numbers is 0.2, or 20%.
Explanation:In this problem, you are being asked to find the probability that a number selected at random from a pool of 50, numbered 1 to 50, is both at least 20 and a prime number. In this case, let's first consider the prime numbers between 1 and 50, of which there are 15 (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47). However, we are looking for prime numbers that are also at least 20. This leaves us with 10 prime numbers (23, 29, 31, 37, 41, 43, 47).
With these 10 prime numbers, and 50 total numbers to choose from, the probability can thus be calculated by dividing the number of successful outcomes by the total number of outcomes. Therefore, the probability P(at least 20 | prime number) is 10/50 or 0.2. This means there is a 20% chance of randomly drawing a number from the bucket that is least 20 and also a prime number.

What is an equation of the line that passes through point (8,0) and is parallel to the line x+y=5
Answer:
y = -x + 5
y - 0 = - (x - 8)
y = -x + 8
Step-by-step explanation:
The required equation of the line is y = 8 - x.
Given that,
To determine an equation of the line that passes through the point (8,0) and is parallel to the line x+y=5
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
Given equation,
x+y=5
y = -x + 5
m = -1
Since the slope of parallel lines are equals.
So the equation of the line is given as, which is passing by (8,0)
y - 0 = -1 (x - 8)
y = 8 - x
Thus, the required equation of the line is y = 8 - x.

In November, Mr. Lee’s students read 50 books. In December, they read 40 books.
What is the percent increase or decrease in the number of books they read?
Answer:
20% decrease
Step-by-step explanation:
Start by dividing 40 by 50.
40/50 = 0.8
0.8 is the decimal form of 80%. So now we know that 40 is 80% of 50. This means that the remaining 20% is the difference between the books read in November and December.
Nadia says the hypotenuse of the right triangle has a length of 73 because the Pythagorean theorem states that (28+45)squared equals to 73squared. Which describes her solution?
Answer: Her solution is incorrect. The hypotenuse is 53 units
Step-by-step explanation: The error occurred when she quoted the Pythagorean theorem. She added up both sides and squared them and made the answer equal to the square of the hypotenuse. She was supposed to have squared them first, before adding up.
The Pythagorean (or Pythagoras) theorem states that the sum of the squares of two sides of a right angled triangle equals the square of the hypotenuse of the triangle. That is, in triangle ABC, if the hypotenuse is given as line AC, the Pythagoras theorem states that
AC^2 = AB^2 + BC^2
Where AC is the hypotenuse and AB and BC are the other two sides.
In Nadia’s solution, if the hypotenuse is given as 73, and the other two sides are 28 and 45, then the Pythagorean theorem properly expressed would be as follows;
73^2 = 28^2 + 45^2
5329 = 784 + 2025
5329 ≠ 2809
As we have determined, writing out the expression as
73^2 = (28 + 45)^2 is very incorrect as this is not the Pythagorean theorem and of course, the triangle cannot have 73 as its hypotenuse as we have determined by properly writing out the Pythagorean theorem.
The correct solution is as follows;
AC^2 = AB^2 + BC^2
AC^2 = 28^2 + 45^2
AC^2 = 784 + 2025
AC^2 = 2809
Add the square root sign to both sides of the equation
AC = 53
Therefore, the hypotenuse is 53 units
It would be C, because when you find the length using th pythagreon theorem... you can begin to see the relationship through all of the figures and side lengths... Make sense?

Step-by-step explanation
4/5 X 10=8 because
[tex]\frac{4}{5}[/tex] X [tex]\frac{10}{1}[/tex] -->we do the denominator first so 5 x 1 = 5 so now it's
[tex]\frac{4}{5}[/tex] [tex]\frac{10}{5}[/tex] so 4 X 10= 2 x 5(we replace 10 with that ) over 5 and the you will be left with 4 x 2 over 5 that is because 5 and 5 canceled out so
now you're left with this 4 x 2 = 8 so 8 is you final answer without the fraction :) hope this helps

if you look 3*3=9 5*3=15 8*3=24 and 10*3=30 so they are taking x*3
Answer:
Y=3x
Step-by-step explanation:
The way a function table works is how x has something done to it to equal y. So if x =4, and y=16
You could formulate the equation y= 4x.
So if we look at the patterns
3 to 9
5 to 15
8 to 24
10 to 30
Y is equal to x times 3.
3(x)·3=9(y)
3(x)=y
3x=y
