Find the height in feet of the missile after 5 seconds in the air
Answers
The height in feet of the missile after 5 seconds in the air is; 875 ft
How to find the height of a Projectile?
We are given the quadratic function of the height in terms of time, x, in seconds as; h(x) = - 17x² + 260x
where;
h(x) is height after x seconds
x seconds is time of missile in air when thrown.
Thus, after five seconds, we have;
h(5) = - 17(5)² + 260(5)
h(5) = -425 + 1300
h(5) = 875 feet
Complete question is;
A missile is launched from the ground. Its height, h(x), can be represented by a quadratic function in terms of time, x, in seconds.
After 1 second, the missile is 243 feet in the air; after 2 seconds, it is 452 feet in the air.
The height of the can be represented by this function:
h(x) = - 17x² + 260x
Find the height, in feet, of the missile after 5 seconds in the air.

This is a dot plot of the number of text messages sent in a day by a sample of students at a local high school. The sample consisted of 30 students and was selected as representative of the population.
a. What do the six values of 0 on the dot plot represent?
b. Since the sample is representative of the population, describe what you think the dot plot of the entire population will look like.
Answers
The six values of 0 shown on the dot plot represent that 6 students out of the 30 sampled did not send any text messages daily.
With the sample being representative of the population, a dot plot for the entire population would have the same proportions as the sample but with a larger number of students.
What does the dot plot show?The number of dots above a number indicates the number of students who send that number of text messages daily.
As there are 6 dots over 0, it means that 6 students do not send any text messages daily.
Seeing as the sample is representative of the entire population, a dot plot for the whole school would have a larger number of dots over each number but the proportions would be the same as the sample.
For instance, the proportion of total students who don't send any messages per day is:
= 6 / 30
= 20%

Fill in the missing number in this sequence:
400, 200, { } , 50, 25
Answers
Answer:
100
Step-by-step explanation:
In this sequence, we can observe that the consistent change between each number in the series is divided by half.
From 400, we divide by 2 to get 200.
400 / 2 = 200
From 50, we divide by 2 to get 25.
50 / 2 = 25
So, to fill in the number after 200, we should logically divide by 2:
200 / 2 = 100
100 also fits into the following numbers, because 100 / 2 is 5.
Answer:
The missing number would be 100
Step-by-step explanation:
You're essentially cutting the numbers in half. For example:
half of 400 would be 200
half of 200 is 100
half of 100 is 50
half of 50 is 25

13.89%
Answers
The value of the first die can be any number except for 1 because even if the second die rolls a 6, the total will only be 7. This means that there is a 5/6 chance of rolling an appropriate number with the first die. The second die has a 1/6 chance of rolling any given number. Any given number can be added to only one of the five numbers from the previous die to equal an 8. As a result, both numbers must be multiplied.
5/6 x 1/6 = 5/36 or 13.89%

Answers
Answer:
143.8m^2
Step-by-step explanation:
surface area of a cylinder has the formular
2πr(r+h)
from the question,
radius= diameter/2 = 3.2/2 = 1.6m
height (h) = 12.7m
Area= 2× 3.142×1.6(1.6+12.7)
Area= 10.0544(14.3)
Area= 143.77
Area= 143.8m^2 to 1 decimal places
Answer: 174.3
Step-by-step explanation: diameter of cylindrical tank = 3.2m
so radius is half of 3.2m
length= 12.7m
T.S.A of tank = 2pie r ( r+h)
2 x 3.14 x 3.2/2 ( 3.2/2 + 12.7 )
= 174.29
rounding it off to one decimal the answer would be 174.3

Find the equation that is parallel to 2x-y=7
Answers
Answer:
Below
Step-by-step explanation:
Lines that are parallel have the same slope, so all lines parallel to the one given have the same slope as it does. That slope value is most easily seen by transforming the given equation to slope-intercept form
(y = mx + b).
This line would be y = 2x -7, so the slope of any line parallel to it must have a slope value of 2.
Hi there.
[tex]= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =[/tex]
First of all, we can't find the equation of the line that is parallel to the line we are provided with in this problem, which is [tex]\bf{2x-y=7}[/tex], until we convert this equation into another form.
.
.
This form has a name, and it's called "[tex]\bf{Slope-Intercept\:Form}[/tex].
.
.
So first, what we need to do is subtract 2x from both sides:
.
[tex]\bf{-y=7-2x}[/tex]
.
It's not mandatory, but we can re-arrange the terms "7" and "-2x":
.
[tex]\bf{-y=-2x+7}[/tex]
.
Last step: Divide both sides of the equation by -1:
.
[tex]\bf{y=2x-7}[/tex]
.
"-2x" turned into "2x" because a negative number multiplied or divided by a negative number equals a positive number.
.
"7" turned into "-7" because a positive number multiplied or divided by a negative number equals a negative number.
.
Now, our equation is in "Slope-Intercept Form".
.
Remember that "Slope-Intercept Form" looks like this:
.
[tex]\bf{y=mx+b}[/tex].
.
Now what we need to find is the equation of the line.
.
Let's skim through the provided information to see whether or not there's some information that can help us find the equation.
.
We're also provided with the fact that these lines, or equations, are parallel.
.
What that means is if two lines are parallel, their slopes are the same.
.
The slope of the line whose equation we just found is -2 (it's the number next to "x").
.
I hope that this helped clear your doubts; if any are left, please ask.
.
I wish you a nice rest of your day.

Solve |5x + 30| = 10x Identify the solution and an extraneous solution
Answers
Answer:
B
Step-by-step explanation:
the absolute value function always gives a positive result
However, the value inside can be positive or negative, that is
5x + 30 = 10x or - (5x + 30) = 10x
solving both
5x + 30 = 10x (subtract 5x from both sides )
30 = 5x ( divide both sides by 5 )
6 = x
or
- (5x + 30) = 10x
- 5x - 30 = 10x ( add 5x to both sides )
- 30 = 15x ( divide both sides by 15 )
- 2 = x
As a check
substitute these values into the equation and if both sides are equal then it is a solution.
x = 6
left side = | 5(6) + 30 | = | 30 + 30 | = | 60| = 60
right side = 10(6) = 60
Then x = 6 is a solution
x = - 2
left side = | 5(- 2) + 30 | = | - 10 + 30 | = | 20 | = 20
right side = 10(- 2) = - 20 ≠ 20
Thus x = - 2 is an extraneous solution
