Answer:
The second flare travels higher, 256 feet, and remains in the air longer, 8 seconds, than the first flare
Step-by-step explanation:
The given parameters are;
The height of the first flare = 196 feet
The duration the first flare spends in the air = 7 seconds
The function representing the height of the second flair is f(t) = -16t(t - 8)
Where;
t = The time since the passenger shot the second flare
The time the flair stays i the air is given by the time it takes for the height, f(t), to be 0 as follows;
f(t) = 0 = -16t(t - 8)
-16t(t - 8) = 0
t = 0, or t = 8
The time the second flare stays in the air = 8 seconds
The maximum height reached by the second flair is given by the finding the maximum point of the curve of the function as follows;
d(f(t))/dt = 0 = d(-16t(t - 8))/dt = -32t + 128 at the maximum point (the coefficient of t² is negative in the quadratic equation)
-32t + 128 = 0
128 = 32t
32t = 128
t = 128/32 = 4
t = 4 at maximum height and f(4) = -16 × 4 × (4 - 8) = 256 feet
The maximum height reached by the second flare f(4) = -16 × 4 × (4 - 8) = 256 feet.
Therefore, the second flare travels higher, 256 feet, and remains in the air longer, 8 seconds, than the first flare, with maximum height of 196 feet, and time in the air of 7 seconds.
The amounts below show the change (measured in feet) in water level over four months. What is the average monthly change in water level?
3/4, -9/4, -11/4, 5/4
Answer:
The average change in water level is: -3/4
Step-by-step explanation:
The average is calculated by adding up all the values and then dividing the sum by total number of values.
Given values are:
3/4, -9/4, -11/4, 5/4
The sum of values will be:
[tex]=\frac{3}{4}+(-\frac{9}{4})+(-\frac{11}{4})+\frac{5}{4}\\=\frac{3}{4}-\frac{9}{4}-\frac{11}{4}+\frac{5}{4}\\=\frac{3-9-11+5}{4}\\=\frac{-12}{4}\\=-3[/tex]
Total number of values is 4
So,
[tex]Average = \frac{Sum}{Values}\\= \frac{-3}{4}[/tex]
Hence,
The average change in water level is: -3/4

Riemann hypothesis, explain please.
Answer:
The Riemann Hypothesis states that all non trivial zeros of the Riemann zeta function have a real part equal to 0.5. ... The Riemann Zeta function has some zeros that are easy to find which are of little interest but there are some other ones that are harder to find which is why the are called non-trivial.

Answer:
x-intercept = -2
Step-by-step explanation:
*Note = x-intercept is when y is 0*
y + 2 = 2(x + 3)
0 + 2 = 2(x + 3)
2 = 2x + 6
2 - 6 = 2x
-4 = 2x
-4/2 = 2x/2
-2 = x
To check, we find the Slope intercept Form and Graph it.
y + 2 = 2(x + 3)
y + 2 = 2x + 6
y = 2x + 6 - 2
y = 2x + 4
5(10k + 1) + 2(2+8k)

Norma's retirement party will cost $24 if she invites 12 guests. If there are 13 guests, how much will Norma's retirement party cost? Solve using unit rates.
Answer:
If there are 13 guests, it would cost Norma $26
Step-by-step explanation:
Since 12 guest equals 24 dollars all you have to do is divide 24/12 which would give you 2dollars. this means that she has to pay 2 dollars per guest. Multiply 13 becuase you want to know how much money it would cost with 13 guests and you get 26 dollars. Hope this helps.
Answer:
It'll cost $26 !
Step-by-step explanation:
if you set it up like this;
[tex]\frac{13}{x}= \frac{12}{24}[/tex]
you can see a few ways of solving this !
one way is cross multiplication .
13 x 24 = 312
312 / 12 = 26
1. Rajeev is is convinced that he and Catarina have the same amount of plants in their
homes. Rajeev has four cacti, 12 zucchini plants, and 10 air plants. Catarina has 12
cacti, 9 air plants, and 4 daisy plants. Is Rajeev correct? Write an equation or
inequality to show your thinking,
Answer:
Rajeev is incorrect.
Step-by-step explanation:
Rajeev has 26 (4+12+10) plants in his home. Catarina has 25 (12+9+4) plants in her home.
From this, we get:
4+12+10 > 12+9+4
because:
26>25
So, Rajeev has more plants than Catarina, rather than the same amount.
You could use the bolded inequality to show your thinking.

Rewrite the rational exponent as a radical. (2 points)
Answer:
Answer: 3) [tex]\sqrt{5}[/tex]
Step-by-step explanation:
Radical Form and Exponent Form
A radical can be expressed as a rational exponent following the identity:
[tex]\displaystyle \sqrt[m]{x^n}=x^\frac{n}{m}[/tex]
We should also recall that:
[tex](x^n)^m=x^{nm}[/tex]
We are given the expression:
[tex]\displaystyle \left(5^{\frac{3}{4}}\right)^\frac{2}{3}[/tex]
Applying the power of power:
[tex]\displaystyle \left(5^{\frac{3}{4}}\right)^\frac{2}{3}=\left(5^{\frac{3}{4}\cdot \frac{2}{3}}\right)[/tex]
Simplifying:
[tex]\displaystyle \left(5^{\frac{3}{4}}\right)^\frac{2}{3}=5^{\frac{1}{2}}[/tex]
Converting to radical form:

Find the value of x that would prove u is parallel to v
Answer:
4
Step-by-step explanation:
If u is parallel to v, so:
(24x - 1) + (20x +5) = 180
24x - 1 + 20x + 5 = 180
24x + 20x - 1 + 5 =180
44x - 1 + 5 = 180
44x + 4 = 180
44x = 180 - 4
44x = 176
44x / 44 = 176 / 44

5u+u–u please tell me !
Answer: = UwU
Step-by-step explanation:
Answer:
5u
Step-by-step explanation:
Simplifying
5u + -1u = u + 15
Combine like terms: 5u + -1u = 4u
4u = u + 15
Solving for variable 'u'.
Move all terms containing u to the left, all other terms to the right.
Add '-1u' to each side of the equation.
4u + -1u = 15 + u + -1u
Combine like terms: 4u + -1u = 3u
3u = 15 + u + -1u
Combine like terms: u + -1u = 0
3u = 15 + 0
3u = 15
Divide each side by '3'.
u = 5
Simplifying
u = 5
6x − 5y = 5
3x + 5y = 4
Write the equation of the line that is parallel to y = -x – 5 and has a y-intercept at (0, 11).
Answer:
[tex]y=-x+11[/tex]
Step-by-step explanation:
We know that the new equation must be parallel to [tex]y=-x-5[/tex].
Therefore, since they are parallel, the slope of the new equation must be the same as the old.
The slope of the original equation is -1.
Therefore, the slope of our new equation is also -1.
We also know that it has a y-intercept at (0, 11).
And as determined earlier, it has a slope of -1.
So, we can use the slope-intercept form:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
We will substitute -1 for m and 11 for b. Thus, our equation is:
[tex]y=-x+11[/tex]
Complete the square to write the equation, 4x2 + 24x – y + 43 = 0, in standard form.

Step-by-step explanation:
Dominic is cutting a rectangular hole in his paper, from top left corner to the bottom right corner. The rectangle will be 4.5 cm long and 3.5 cm wide. which of the following is closest to the distance between the corners of the rectangle?
Answer:
Step-by-step explanation:
So initially you have a square piece of metal, 15" x 15". You cut out squares from the corners of each side with side length x.
So you'll have a sheet that looks something like this now (assuming the formatting works):
_____
__| |__
| |
|__ __|
|____|
Your original side length was 15, but it has now been reduced by x on each side, so you're now going to have a new side length of 15 - 2x
When you fold the box up, the box will have a height of just x.
So you have a base with lengths (15 - 2x) and (15 - 2x), and a height which is just x.
V = l*w*h
So
V = (15 - 2x)(15 - 2x)(x)
= 225x - 60x^2 + 4x^3
