According to the solving the Hight in feet at 2 second is 74.
What is the link between height and time, as well as height and velocity?This asserts that the height (h) of a projectile is equal to the combination of two products: its initial velocity and time in the air, and indeed the acceleration constant as well as half of the time squared.
What is the Max height formula?max = h plus V02 / (4 * g) When launching from the ground, the range is maximized (h = 0). If = 0°, therefore vertical velocity becomes equal to zero (Vy = 0), indicating horizontal projectile motion.
According to the given data:Given h(t)=−16t²+69t
t = 2 sec
substituting the value of t = 2.
h(2)=−16(2)²+69(2).
= -64 + 138
= 74
According to the solving the height and time in feet at 2 second is 74.

6. To make your shot, you need the cue ball to hit point C. Find length CD and use it
to identify the location of C in relation to one of the C corner pockets. For example, if C
is on the upper bumper, your answer might be: 15 inches to the right of the upper left
pocket. Round your answer to the nearest inch. (2 points: 1 point for distance, 1
point for location)
33in is length of CD by using angle of reflection.
What is Angle of reflection?
The angle of reflection is the angle formed by the reflected ray and the normal at the point of incidence on a reflecting surface.The angle formed by the incident and reflected rays is split into two equal angles by the normal line. The angle of incidence is the angle formed by the incident beam and the normal. The angle of reflection is the angle formed by the reflected beam and the normal.CD should be a perpendicular line to CB.
Angle of incidence = Angle of reflection
Angle ACD = Angle EAC
Let the perpendicular intersection point from A to side be G
The two right-angled triangles, CDG and CAG, are similar by AAA.
So DG/AG = CD/CA
46/18 = CD/CA
CD+CA = 96-50 = 46
CA = 46-CD
46/18 = CD/(46-CD)
46*46 - 46CD = 18CD
64CD = 46*46
CD = 33.06 = 33in

First make a substitution, and then use integration by parts to evaluate the integral.
Answer: 1/2 ([tex]\pi[/tex]) sin [tex]\pi[/tex] + ∫ x cos [tex]\pi ^{2}[/tex] dx + c
1/2 ([tex]\frac{\pi }{2}[/tex]) sin [tex]\frac{\pi }{2}[/tex] + ∫ x cos [tex]\frac{\pi }{2} ^{2}[/tex] dx + c
Step-by-step explanation:
We can't just integrate straight away, so we try substitution.
While trying substitution, we observe that we could integrate cos([tex]x^{2}[/tex]) x dx
by substitution.
So, let's split the integrand and use integration by parts.
we can represent θ = x,
so, we can write,
= ∫[tex]x^{3} cos x^{2} dx[/tex]
= ∫ [tex]x^{2} cos (x^{2} )xdx[/tex]
We notice that we could rewrite this as ∫ u cos(u) 1/2 du, but we don't see how to integrate that, so we'll continue with parts for now.)
= ∫ [tex]x^{2} cos (x^{2} )xdx[/tex]
Let u=[tex]x^{2}[/tex] and dv = [tex]cos(x^{2} )xdx[/tex]
Clearly du= 2x dx, and
we can integrate dv by substitution to get.
= 1/2 sin [tex]x^{2}[/tex]
uv - ∫ vdu = 1/2 [tex]x^{2}[/tex] sin([tex]x^{2}[/tex]) - ∫ x sin ([tex]x^{2}[/tex]) dx
Integrate by substitution again to finish.
∫ [tex]x^{3} cos (x^{2}) dx[/tex] = 1/2 [tex]x^{2} sin x^{2}[/tex] + ∫ x cos [tex]x^{2}[/tex] dx + c
Then,
x = √[tex]\pi[/tex] and √[tex]\frac{\pi }{2}[/tex]
∫ [tex]x^{3}[/tex] cos [tex]x^{2}[/tex] dx = 1/2 (√[tex]\pi ^{2}[/tex]) sin √[tex]\pi ^{2}[/tex] + ∫ x cos [tex]\pi ^{2}[/tex] dx + c
= 1/2 ([tex]\pi[/tex]) sin [tex]\pi[/tex] + ∫ x cos [tex]\pi ^{2}[/tex] dx + c
∫ [tex]x^{3}[/tex] cos [tex]x^{2}[/tex] dx = 1/2 ([tex]\frac{\pi }{2}[/tex]) sin [tex]\frac{\pi }{2}[/tex] + ∫ x cos [tex]\frac{\pi }{2} ^{2}[/tex] dx + c

-5x+3y=-30
Find x interception
The x-intercept of given equation is x=6 and point is (6,0).
Given the equation is -5x+3y=-30.
Here, we will find the x-intercept of the given equation.
The x-intercept is the point at which a line intersects the x-axis and the y-intersection is the point where a line intersects the y-axis.
We will find the x-intercept by substituting y=0 and applying the inverse operations.
Firstly we will substitute y=0 in equation, we get
-5x+3(0)=-30
Now, we will simplify this, we get
-5x+0=-30
-5x=-30
Further, we will divide both sides with -5, we get
-5x/-5=-30/-5
x=-6
Hence, the x-intercept of the given equation -5x+3y=-30 is x=6.

The values of the sine and tangent of the angle are √2 / 2 and - 1. By using inverse trigonometric functions, the value of angle is 135° (3π / 4).
How to find the values of other trigonometric functions and the angle behind themAccording to the statement, the cosine of the angle is in the second quadrant and therefore the value of the sine must be positive and the value of the tangent must be negative. Then, the value of the sine is found by the fundamental formula:
sin θ = √(1 - cos² θ)
sin θ = √[1 - (- √2 / 2)²]
sin θ = √(1 - 1 / 2)
sin θ = √(1 / 2)
sin θ = √2 / 2
And the value of the tangent:
tan θ = sin θ / cos θ
tan θ = (√2 / 2) / (- √2 / 2)
tan θ = - 1
By using inverse trigonometric functions, we find that the value of angle is 135° (3π / 4).

the distribution of lengths of rainbow trout from a certain river are normally distributed with a standard deviation of 2.4 inches. it 15% of the rainbow trout are longer than 15 inches, which of the following is closest to the mean of the distribution?
Based on the calculations, the value which closest to the mean of the distribution is equal to: B. 18 inches.
What is a z-value?A z-value is also referred to as a z-score or standard score and it can be defined as a measure of the distance between a raw score and the mean, when standard deviation units are used.
In Statistics, z-values can either be positive or negative and it can be calculated by using this formula:
Z = (x - μ)/δ
Where:
x represents the sample mean or observed data.μ represents the mean.δ represents the standard deviation.If 15 percent of the rainbow trout are longer than 15 inches, then we have:
P(x > 15) = 0.15
From the z-table, the z-value which corresponds to a mean of 0.15 is given by:
z-value = -1.036
Substituting the given parameters into the formula, we have;
Z = (x - μ)/δ
-1.036 = (15 - μ)/2.4
-1.036 × 2.4 = 15 - μ
-2.4864 = 15 - μ
μ = 15 + 2.4864

Borrowed money for 4 years at 9%. Total interest paid was 2520. How much was borrowed
The required amount that was borrowed is 7000.
Given that,
Borrowed money for 4 years at 9%.
The total interest paid was 2520.
To determine how much money was borrowed.
Simple interest is defined as the percentage of earnings on the lending for a period of time
Here,
interest = [principal * rate * time ] / 100
2520 = [principal * 9* 4] / 100
Principal = 2520 * 100 / 9*4
Principal = 7000
So, the principal amount or initial amount is $7000.
Thus, the required amount that was borrowed is 7000.

Brett works for the local farmer, delivering feed and produce to the local community. He uses his own truck for the deliveries. He
gets paid a travel allowance of 64 cents per kilometer travelled. How much car travel allowance would Brett get paid for
travelling a total of 87km?
Select one:
O $55.68
O $67.24
O $54.86
O $45.90
If there is currently $139.50 petty cash in the tin how much do I need to withdraw from the bank to make $200.00 in the tin?
Brett will get paid $55.68 for travelling a total of 87 kilometers at an allowance of 54 cents per kilometer.
According to the International System of Units (SI), one kilometer is equal to 1,000 meters in American English. The United States and the United Kingdom are significant outliers, where the statute mile is the unit of measurement used to express distances between geographical locations on land.
One Kilometer is roughly equivalent to 0.621 miles.
Brett delivers produce for the farmer using his truck.
He gets paid a travel allowance of 64 cents per kilometer.
So to calculate his total allowance we multiply the allowance with the distance travelled.
Brett gets paid: $0.64×87=$55.68
Hence Brett gets paid $55.68. So the first option is correct.
