A Men Trhows A Ball Off The Top Of A Building That is 46 feet hight he trows the ball with an anitial velocity of 33 ft/sec
a. write the equation to model this problem
b. use the model to estimate the height of the ball at 2.5 seconds.
c. what is the ball's maximum height?
The height of the ball at 2.5 seconds is 42.75feet
How to model the equation of a bodyThe standard equation for the equation is modeled as:
[tex]h(t)=t^2-v_0t+d[/tex]
Given the following parameters;
[tex]v_0=33ft/sec\\d = 46ft[/tex]
Substitute into the expression to have:
[tex]h(t)=t^2+33t-46[/tex]
The height of the ball at 2.5 seconds is xpressed as:
h(2.5) = (2.5)^2+33(2.5)-46
h(2.5) = 6.25+82.5-46
h(2.5) = 42.75 feet
Hence the height of the ball at 2.5 seconds is 42.75feet
The velocity of the ball at the maximum height is zero, hence;
v = dh/dt = 2t + 33
2t = 33
t = 16.5secs

The average height of 5 students is 1.45 m. If one student left the group,the average height of the remaining four of them is 1.44 m. What was the height of the student who left
Answer:
4 students
Step-by-step explanation:
The average = sum of all observations divided by a number of observations. Sum of heights of 4 students = 1.44 ×4 = 5.76. Clearly, height of student who left = Sum of all heights - Sum of heights of 4 students.
Can someone please help me with number 6?
Step-by-step explanation:
substitute a with 2 and b with 3
2x+3
because it's the same equation it should just be an equal sign.
Answer:
Simplifying
ax + b = 2x + 3
Reorder the terms:
ax + b = 3 + 2x
Solving
ax + b = 3 + 2x
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-1b' to each side of the equation.
ax + b + -1b = 3 + -1b + 2x
Combine like terms: b + -1b = 0
ax + 0 = 3 + -1b + 2x
ax = 3 + -1b + 2x
Divide each side by 'x'.
a = 3x-1 + -1bx-1 + 2
Simplifying
a = 3x-1 + -1bx-1 + 2
Reorder the terms:
a = 2 + -1bx-1 + 3x-1

Answer:
[tex]y=\boxed{-\dfrac{1}{4}}\left(x-\boxed{-2}\:\right)^2+\boxed{4}[/tex]
Step-by-step explanation:
The graph of a quadratic function is symmetrical.
The axis of symmetry is the vertical line through the vertex of the parabola so that the left and right sides of the parabola are symmetrical.
From inspection of the given table, the axis of symmetry is x = -2 as the y-values of x = -3 and x = -1 are both 3.75.
Therefore, the vertex is (-2, 4).
Vertex form of a quadratic equation:
[tex]y=a(x-h)^2+k[/tex]
where:
(h, k) is the vertex.a is some constant.Substitute the vertex and one of the other points into the vertex formula and solve for a:
[tex]\begin{aligned}y&=a(x-h)^2+k\\\implies 3&=a(0-(-2))^2+4\\3&=a(2)^2+4\\3&=4a+4\\-1&=4a\\a&=-\dfrac{1}{4}\end{aligned}[/tex]
Substitute the vertex (-2, 4) and the found value of a into the formula to create an equation for the function:
[tex]y=\boxed{-\dfrac{1}{4}}\left(x-\boxed{-2}\:\right)^2+\boxed{4}[/tex]

Zayn knows that during the month of April, the probability that it is windy on his way to work is 0.5, the probability that it rains on his way to work is 0.7 and the probability that it is both windy and raining on his way to work is 0.3.
Work out:
the probability it is windy, given that it is raining
the probability it is raining, given that it is windy.
Step-by-step explanation:
the probability it is windy, given that it is raining = p(w|r)=p(wπr)/p(r) =0.3/0.7 =3/7= 0.429
the probability it is raining, given that it is windy.
p(r|w)=p(wπr)/p(w) =0.3/0.5 =3/5 = 0.6

The simplified expression that represents the area of the parallelogram is 2x^3 - 6x^2 -14x + 24
How to calculate the area of a parallelogramArea of a parallelogram = base * height
Given the following
Base = 2x^2 + 2x - 6
Height = x - 4
Substitute into the formula to have:
Area of a parallelogram= (x-4)(2x^2 + 2x - 6)
Area of a parallelogram= 2x^3 + 2x^2 - 6x - 8x^2 - 8x + 24
Area of a parallelogram= 2x^3 - 6x^2 -14x + 24

D.
the maximum profit the manufacturer can earn from selling their product
Answer:
the selling price of the product that will generate zero dollars in profit
Step-by-step explanation:
PLATO
The x-intercept of the given data represents the selling price of the product that will generate zero dollars in profit.
Intercepts of a straight line:The straight line intersecting any axis, the distance between the point of intersection on-axis and origin is called an intercept of the line.X intercept: When the Line intersects the X-axis at point (a,0), then a is the X intercept.Y-intercept: When the Line intersects the Y-axis at point (0,b), then b is the X intercept.How to solve the given problem?Plot the given data on the graph, with x on the x-axis and P(x) on Y-axis.As per the definition of X intercept, where the value of y - coordinate is zero, the x coordinate represents the x intercept.Thus the x-intercept for the given data is 100.As the P(x) defines the profit of manufacturer when the product is sold for x dollars.Thus, the x-intercept represents the selling price of the product that will generate zero dollars in profit.

A lawn sprinkler sprays water 4 feet in all direction as it rotates.
Find the area of the lawn the sprinkler covers. Use 3.14 for pi.
Solution:
We know that:
To find the area of a circle, use πr².Since the sprinkler sprays water 4 feet in all directions, the radius will be 4 ft.
This means that:
Area of circle = (3.14)4²Now, let's solve for the area.
=> Area of circle = (3.14)16=> Area of circle = 3.14 x 16=> Area of circle = 50.24 ft² [Option D]This is a linear equation what is the answer

if a sphere and a cone have the same radius and height how is the volume of a sphere related to the volume of a cone?
Please help this is half my grade!!!!
Answer:
The volume of the silo is about 142.3 cubic meters. Try It! The volume of a sphere is twice the volume of a cone that has the same circular base and height. The formula for the volume of a sphere with radius r is V= r3.
Step-by-step explanation:
Notice that if a cone and a sphere have equal radius, and if the cone has a height equal to its radius, then the cone will fill the sphere exactly four times. This means that the volume of the sphere is $4 times the volume of the cone.

Answer:
11.31
Step-by-step explanation:
Use the pythagorean theorem: c^2=a^2+b^2
18^2=14^2+b^2
324=196+b^2
128=b^2
b=11.31
[tex][Hello,BrainlyUser][/tex]
Answer:
[tex]\sqrt{128}[/tex]
Step-by-step explanation:
Right, let write down the Pythagorean Theorem equation or standard form of it. before we plug in the numbers.
[tex]a^2+b^2=c^2[/tex]
Right, so that is the equation of Pythagorean Theorem. So let plug in the numbers of b and c.
[tex]a^2+14^2+18^2[/tex]
So we have our values of b and c. Now, how do we find the missing number?
Well, let simplify thing further by squaring the numbers we have already.
[tex]a^2+196+324[/tex]
We will now subtract 196 from both side which gives us:
[tex]a^2=128[/tex]
Now we can square root the answer.
[tex]\sqrt{a^2} =\sqrt{128}[/tex]
Now, we are left with this:
[tex]a=\sqrt{128}[/tex]
So the final answer is [tex]\sqrt{128}[/tex] or the decimal value which is [11.31370849]
Round: 11.31
