Answer:
The displac ment between t = 1 and t = 4 is 272 feet
Step-by-step explanation:
To get the displacement of the ball, we first need to get the equation for the position of the ball with respect to time.
We can do this by differentiating the velocity equation given:
v(t) = -32t +96
integrating between the limits of t = 1 and t = 4, we have
[tex]s = \int\limits^4_1 {-32t +96} \, dt[/tex]
[tex]s(t) = -32t^2/2 +96t[/tex]
[tex]s =[ -16t^2 +96t] t = 4, t =1[/tex]
where t = 4.
s = 256 + (96) =352 feet
Where t = 1
s = 80
Displacement of the ball = 352 -80 = 272ft
The displac ment between t = 1 and t = 4 is 272 feet
GE = 3x - 11 FD = 2.x Find GE
Can someone help me??
Answer:
22
Step-by-step explanation:
Given the following
GE = 3x - 11 FD = 2x
Let us assume GE is parallel to FD, hence GE = FD
3x - 11 = 2x
3x - 2x = 0+11
x = 11
Get GE
GE = 3x - 11
GE = 3(11)-11
GE= 33 - 11
GE = 22
Hence the length of GE is 22

Step-by-step explanation:
Cos m = 35/37 = 0.94
Cos n = 12/37 = 0.32
Sin m = 12/37 = 0.32
Sin n = 35/37 = 0.94
tan m = 12/35 = 0.34
tan n = 35/12 = 2.91

Find the median for the number of pencils.
Answer:
The median is 2
Step-by-step explanation:
Here, we want to get the median for the number of pencils
Firstly, we have to write out the numbers that form the box plot ; we have this as;
1,1,1,2,2,2,2,3,3,5
the median is sum of the 5th and 6th term divided by 2
The 5th term is 2
The 6th term is 2
So the median is;

now recall L'Hôpital's rule
[tex] \displaystyle \lim_{x \to c} \frac{f(x)}{g(x)} = \lim_{x \to c} \frac{f'(x)}{g'(x)} [/tex]
first simplify the complex fraction:
[tex]\displaystyle \lim_{n\to \infty } \frac{n+ 1}{2n} [/tex]
apply L'Hôpital's rule:
[tex]\displaystyle \lim_{ n\to \infty } \frac{ \dfrac{d}{dn} n+ 1}{ \dfrac{d}{dn} 2n} [/tex]

when n=[tex] \infty [/tex]
so,
[tex] \displaystyle \lim_{n\to \infty } \frac{1 + 2 + 3 + \dots {\dots} +n }{ {n}^{2} } [/tex]

Regroup terms
(x² - 10x) + (y² + 8y) = -37
Complete the square
(x² - 10x + 5²) + (y² + 8y + 4²) = -37 + 5² + 4²
(x² - 5)² + (y² + 4)² = 2²

9. Lines A and B are parallel lines. Find the measures of angles 1, 2 and 3.
Answer:
<1 = 33
<2 = 90
<3 = 57
Step-by-step explanation:
<3 = 57 because of alternate interior angles
<2 + <3 + 33 = 180
<2 + 57 + 33 = 180
<2 + 90 = 180
<2 = 90
<1 + <2 + 57 = 180
<1 + 90 + 57 = 180
<1 + 147 = 180
<1 = 33

Which diagram shows a pair of angle measure that proves lines c and d are parallel?
Answer:
C
Step-by-step explanation:
At first glance, it seems like all the answers work. But some careful thinking allows us to find the correct answer.
For this question, we will be using the process of elimination.
First, we can eliminate D, because it does not provide any angles on line d, so we cannot prove that line c is parallel to line d.
Second, we can eliminate A. It seems that the 2 angles makes it so that lines c and d must be parallel, however, that is only true if lines a and b are parallel. Since we don't know whether or not lines a and b are parallel, we cannot prove that lines c and d are parallel, so we can eliminate this choice.
Third, we can eliminate B. Like the diagram in A, this diagram can only prove lines c and d are parallel if lines a and b are parallel, and since we don't know whether or not lines a and b are parallel, we cannot prove tat lines c and d are parallel, so we can eliminate this choice.
We are left with C, so the answer must be C.
Of course, just to make sure, we will also check diagram C. Because the 2 angles provided in the diagram are on line a and none are on line b, we do not need line a to be related to line b in any way, as such we can pretend that line b does not exist in this diagram. We can then see that lines c and d must be parallel for this diagram, or else the angles would not work, so C is correct.
Two angles whose sum is 180° are called supplementary angles. The correct option is C.
What are supplementary angles?Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, that if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.
When two parallel lines are cut by a transverse. The angles formed on the exterior of the parallel lines are known as the Exterior Angle.
Now, For two lines two be parallel in the given diagram the measure of the angle the exterior angle on the same side of the transverse should be supplementary to each other.
The diagram shows a pair of angle measure that proves lines c and d are parallel in option c. This is because lines c and d are parallel and a is transversal to the two lines. And the measure of the exterior angles formed on the same side of the transversal is supplementary.
Hence, the correct option is C.

Find the absolute extrema of the given function: f(x)=x^4 − 3x^2 + 4, on the interval [−1,1]
Answer:
The absolute maximum is 4, and the absolute minimum is 2.
Step-by-step explanation:
We are given the function:
[tex]f(x)=x^4-3x^2+4[/tex]
And we want to find the absolute extrema of the function on the interval [-1, 1].
So, we will find the smallest and largest y-value within the interval. First, we can evaluate the function at its endpoints. So:
[tex]f(-1)=(-1)^4-3(-1)^2+4=2[/tex]
And:
[tex]f(1)=(1)^4-3(1)^2+4=2[/tex]
Our endpoints are (-1, 2) and (1, 2).
Recall that extrema only occurs at critical points. Critical points are where the derivative of the function equals 0. So, we can find the derivative of the function:
[tex]\displaystyle f'(x)=\frac{d}{dx}\left[x^4-3x^2+4\right][/tex]
Differentiate:
[tex]f'(x)=4x^3-6x[/tex]
Set the function equal to 0:
[tex]0=4x^3-6x[/tex]
Solve for x. Factor:
[tex]2x(2x^2-3)=0[/tex]
Zero Product Property:
[tex]2x=0\text{ or } 2x^2-3=0[/tex]
Solve for each case. Therefore:
[tex]\displaystyle x=0\text{ or } x=\pm\frac{\sqrt6}{2}[/tex]
The second case is outside of our interval. So we can ignore it.
Evaluate the function at x = 0:
[tex]f(0)=(0)^4-3(0)^2+4=4[/tex]
Therefore, for our function on the interval [-1, 1], the absolute maximum is 4, and the absolute minimum is 2.

A soccer dome shaped like a hemisphere has a volume of 450,000 m^3. What is the area of its field? Use 3.14 for pi
Answer:
Step-by-step explanation:
450,000=2/3(3.14)r
450,000 times 3/2=2/3(3.14)r times 3/2
675,000=3.14r
675,000/3.14=3.14r/3.14
about 214968.15287=r
So now we know r. We can use it to find the area of the circle
Pi times r squared
3.14 times 214968.15287 squared
area equals about 15573.44815
The area of the hemisphere is 45065.41
How to determine the area?The given parameters are:
Shape = Hemisphere
Volume = 450000
The volume is calculated as:
Volume = 2/3pi r^3
This gives
450,000=2/3 * 3.14 * r^3
Solve for r^3
r^3 = 450000 * 3/(2 * 3.14)
This gives
r^3 = 214968.152
Take the cube roots
r = 59.9
The area is then calculated as;
Area = 4pi r^2
This gives
Area = 4 * 3.14 * 59.9^2
Evaluate
Area = 45065.41
Hence, the area of the hemisphere is 45065.41
