Find the rate of change in the submarine's elevation in feet per second. Round your answer to the nearest tenth.
Answer:
25.3 feet per second
Step-by-step explanation:
First, let's find how much did she go down in those 3 seconds.
266-190=76
Now, let's divide 76 by 3 to find how much did she go down in 1 second
76/3=25 R1
Now, let's change 25 R1 to a Fraction.
25 remainder 1 to fraction will be 25[tex]\frac{1}{3}[/tex]
Now, let's find the decimal answer
25[tex]\frac{1}{3}[/tex] will be 25.33(33333)
Now, let's round our answer to the nearest tenth
25.33
so, 3 is closest to 0 not to 10
So hence, our answer is 25.3
So, the submarines elevation was changing at a rate of 25.3 feet per second

The product of two consecutive positive integers is 17 more than 5 times their sum. Find the numbers
Answer:
The no. are 11 and 12
Step-by-step explanation:
n(n+1)=17+5(2n+1)
n^2 +n=17+10n+5
n^2 -9n-22
Splitting the middle term
n^2 -11n+2n -22
n(n-11)+2(n-11)
(n-11)(n+2)
As n cannot ne negative,
n=11 and 12(consecutive no.)

The two of the consecutive positive integers whose product is 17 more than 5 times their sum are 11 and 12.
What are Integers?An integer is a complete number, therefore, not including the decimals and fractions. And it that can be either positive, negative, or zero.
Integer examples include -5, 1, 5, 8, 97, and 3,043.
Non-integer numbers include: -1.43, 1 3/4, 3.14, and more.
Let the first of the two consecutive integers be represented by x. Then, the other number can be written as (x+1).
Now, the product and the sum of the two numbers can be written as,
Product = x(x+1) = x² + x
Sum = x + (x+1) = 2x + 1
Further, it is given that the product of two consecutive positive integers is 17 more than 5 times their sum. Therefore, we can write,
x² + x = 17 + 5(2x + 1)
x² + x = 17 + 10x + 5
x² + x - 17 - 10x - 5 = 0
x² - 9x - 22 = 0
x² - 11x + 2x - 22 = 0
x(x - 11) + 2(x - 11) = 0
(x - 11)(x + 2) = 0
x = -2, 11
Thus, there are two numbers that can fulfil the given condition but since it is mentioned that we only need two positive consecutive integers. Therefore, the two numbers are 11 and 12.

The answer is: (x-3)(x-1)(x+2)
Because the first term is x^3, it means that there must be 3 independent x's multiplying by each other. From there you just have to est what numbers to pair them with. If that doesn't make sense let me explain more:If you have x^2 it will be:(x + y) (x + z) If you have x^3 it will be: (x + y) (x + z) (x + g) If you have x^4 it will be: (x + y) (x + z) (x + g) (x + f) etc; now all you have to do after you pick which one it matches with, it just find what the value of y, z, and g are through trial and error. I am not showing all my trial and error because it is long to type out, easier to just explain the process.

Enola gave out a survey to some students in her school about their favorite color. Students could choose between blue and purple. 371 of those surveyed said their favorite color was blue. 47% of the students surveyed said their favorite color was purple. How many students were surveyed in total?
Using proportions, it is found that 700 students were surveyed in total.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, we have that 100 - 47 = 53% of the total number of students had blue as their favorite color, and this amount is of 371, hence:
0.53n = 371
n = 371/0.53
n = 700.

Answer:
false
Step-by-step explanation:
if x equals 5 then 4 times 5 would equal 20 not 19
Answer:
False
Step-by-step explanation:
Because if we subsitute x as 5.
4x = 19
4(5) = 19
20 = 19
4 times 5 equals 20, not 19. Therefore it is false.

|| ▼ Answer ▼ ||
The average rate of change per year from 1 to 5 is 8inches
Step-by-step explanation:

The snack stand at the local baseball field sells cherry and lemon snow cones. Yesterday, the stand sold 4 cherry snow cones for every 1 lemon snow cone sold. If there were 30 more cherry snow cones than lemon snow cones sold yesterday, how many snow cones were sold altogether?
Given:
The stand sold 4 cherry snow cones for every 1 lemon snow cone sold.
There were 30 more cherry snow cones than lemon snow cones sold yesterday.
To find:
The number of snow cones which were sold altogether.
Solution:
Let x be the number of lemon snow cone sold.
The stand sold 4 cherry snow cones for every 1 lemon snow cone sold.
So, number of cherry snow cone sold = 4x
There were 30 more cherry snow cones than lemon snow cones sold yesterday.
[tex]4x-x=30[/tex]
[tex]3x=30[/tex]
Divide both sides by 3.
[tex]x=\dfrac{30}{3}[/tex]
[tex]x=10[/tex]
Total number of snow cones sold is
[tex]\text{Total number of snow cones sold }=x + 4x[/tex]
[tex]\text{Total number of snow cones sold }=5x[/tex]
[tex]\text{Total number of snow cones sold }=5(10)[/tex]
[tex]\text{Total number of snow cones sold }=50[/tex]
Therefore, 50 snow cones were sold altogether.

Help Please Help Its A Math Problem : Maria threw her math book off a 30 foot building. The equation of the book can be represented by the equation: h(t)= -16t^2+24t+30 where t is the time in seconds and h is the height in feet. What is the maximum height of Maria's math book?
Question options:
0.75
30
39
12
p.s I will brainlist please and thank you.
Answer:
39 feet
Step-by-step explanation:
The equation of the path of the book is an upside down parabola.
We can find the x-coordinate of the vertical axis.
The x-coordinate of the maximum point is
x = -b/2a
for a parabola written in the following form
f(x) = ax² + bx + c
We have -16t² + 24t + 30, so we have
a = -16
b = 24
c = 30
t = -b/2a = -24/(2 × (-16)) = -24/(-32) = 0.75
The maximum height occurs at time = 0.75 seconds.
Now we plug in the time into the equation to find the maximum height.
h(x) = -16t² + 24t + 30
h(0.75) = -16(0.75)² + 24(0.75) + 30
h(0.75) = -9 + 18 + 30
h(0.75) = 39
Answer: 39 feet
What is the slope-intercept equation of the line below?
A. y = -2x - 1
B. y = 2x + 1
O C. y=-2x+1
O D. y = 2x - 1
Answer:
Pretty sure it is A. y = -2x - 1
Step-by-step explanation:
y = mx + b
m is slope
b is y - intercept
y-intercept = point where line intercepts the y - axis. in this graph, it intercepts at (0, -1)
by counting the squares, you see this line has a rate of change of up two left one which is 2/-1 or -2. that is the slope
your photo is super blurry so it's hard to tell, but i'm 99% sure i am correct.
The slope-intercept equation of the line is y=-2x-1. Therefore, option A is the correct answer.
We need to find the slope-intercept equation of the line.
What is the slope-intercept equation?Slope-intercept form, y=mx+b, of linear equations, emphasizes the slope and the y-intercept of the line.
The coordinates of the line (-1, 1) and (1, -3).
The slope of the equation is [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
Now, m=-3-1/1+1=-2
Substitute m=-2, x=-1 and y=1 in y=mx+b.
That is, 1=-2(-1)+b⇒b=-1
So, y=-2x-1
The slope-intercept equation of the line is y=-2x-1. Therefore, option A is the correct answer.

Note the x^2 term, 21 can be divided up into 1,3,7,21
and the constant term, 14 is divisible by 1,2,7
Also, note that -55 = -7*7 - 2*3
Break up 21x^2 into 7x*3x and -55x into -49x - 6x,
21x^2 - 55x + 14
