Zachary is an engineer and studies trains. He found this interesting problem involving a passenger train and a freight train:
A passenger train left New York and traveled North while a freight left from the same place, at the same time and traveled South. After traveling for 6 hours the trains were 720 miles apart. If the passenger train was traveling at 80 mph, how fast was the freight train traveling
Answer:
40 m/hr
Step-by-step explanation:
6 hours * 80 m/hr + 6 hours * x m/hr = 720 miles
6 * 80 + 6 * x = 720
x = 40 m/hr
A football is thrown from the top of the stands, 50 feet above the ground at an initial velocity of 62 ft/sec and at an angle of elevation of 45 degrees.
a.) Write a set of parametric equations that model the football's horizontal and vertical movement.
b.) The football reaches its maximum height at t=1.37 seconds. Using your parametric equations from part "a", determine the location of the football at its maximum height relative to the starting point.
a. i. The parametric equation for the horizontal movement is x = 43.84t
ii. The parametric equation for the vertical movement is y = 50 + 43.84t
b. the location of the football at its maximum height relative to the starting point is (60.1 ft, 60.1 ft)
a. Parametric equationsA parametric equation is an equation that defines a set of quantities a functions of one or more independent variables called parameters.
i. Parametric equation for the horizontal movementThe parametric equation for the horizontal movement is x = 43.84t
Since
the angle of elevation is Ф = 45° and the initial velocity, v = 62 ft/s,the horizontal component of the velocity is v' = vcosФ.
So, the horizontal distance the football moves in time, t is x = vcosФt
= vtcosФ
= 62tcos45°
= 62t × 0.7071
= 43.84t
So, the parametric equation for the horizontal movement is x = 43.84t
ii Parametric equation for the vertical movementThe parametric equation for the vertical movement is y = 50 + 43.84t
Also, since
the angle of elevation is Ф = 45° and the initial velocity, v = 62 ft/s,the vertical component of the velocity is v" = vsinФ.
Since the football is initially at a height of h = 50 feet, the vertical distance the football moves in time, t relative to the ground is y = 50 + vsinФt
= 50 + vtcosФ
= 50 + 62tsin45°
= 50 + 62t × 0.7071
= 50 + 43.84t
b. Location of football at maximum height relative to starting pointThe location of the football at its maximum height relative to the starting point is (60.1 ft, 60.1 ft)
Since the football reaches maximum height at t = 1.37 s
The x coordinate of its location at maximum height is gotten by substituting t = 1.37 into x = 48.84t
So, x = 43.84t
x = 43.84 × 1.37
x = 60.0608
x ≅ 60.1 ft
The y coordinate of the football's location at maximum height relative to the ground is y = 50 + 48.84t
The y coordinate of the football's location at maximum height relative to the starting point is y - 50 = 48.84t
So, y - 50 = 48.84t
y - 50 = 43.84 × 1.37
y - 50 = 60.0608
y - 50 ≅ 60.1 ft
So, the location of the football at its maximum height relative to the starting point is (60.1 ft, 60.1 ft)

From the given:
There are letter tiles in a bag. Four A’s, five B’s, six C’s and five D’s. You select one tile, replace it, and then draw another.
To Find:
P( A and A)=______
Solution:
Since it given that:

What is the value of x?
1) 48
2) 66
3) 24
4) 33
Answer:
x = 66°
Step-by-step explanation:
The angles lie on a straight line.
→ A straight line has total 180 degrees
2(x) + 48° = 180°2(x) = 180° - 48°2(x) = 132°x = 66°Answer:
2) 66
Step-by-step explanation:
2x + 48° = 180° (Angles in linear pair)
-> 2x = 180° - 48°
-> 2x = 132°
-> x = 132°/2
-> x = 66°
1. Find the unknown length of the side labeled x.

Step-by-step explanation:
Find the slope of the line that is parallel and perpendicular to the following equation.
2x - y = 1
Answer:
Slope of the line that is parallel: 2
Slope of the line that is perpendicular: [tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
For the parallel line:
Rewrite your equation to slope-intercept form: y = mx + b
y = mx + b
m = slopeb = y-intercept (when x = 0)2x - y = 1 <== subtract 2x to both sides
-2x -2x
-y = -2x + 1 <== divide both sides by -1
/-1 /-1
y = 2x - 1
The slope of the line that is parallel to this line is 2.
For the perpendicular line:
*Perpendicular lines have negative reciprocals*
Steps:
1. Take your original slope (2)
2. Flip it (1/2)
3. Change the sign (-1/2)
For a slope of 2, the reciprocal would be: [tex]-\frac{1}{2}[/tex]
Hope this helps!
Note that.
Slopes of parallel line are equal
Slopes of perpendicular lines are negative reciprocals
So
2x-y=1y=2x-1Compare to slope intercept form
slope=m=2Slope of the parallel line=2
Slope of the perpendicular line=-1/2

The required height of the pentagonal prism is 19 cm
Given that,
A figure of a pentagon prism is shown with
The volume of the prism = 2850 cubic cm
Side of pentagon base = 12 mm.
And the perpendicular distance from the center to the side = 5 mm.
Volume is defined as the ratio of the mass of an object to its density.
Or in mathematics volume can be calculated as the area of the base multiplied by the height.
In order to get the height of the prism first, we have to calculate the area of the base and then divide the volume by its base area to get its height.
The base area = 5/2 * side * perpendicular height to side from center.
= 5 / 2 * 12 * 5
= 150
The volume of the prism = base area * height
2850 = 150 * height
height = 2850/15
= 19 cm
Thus, the required height of the pentagonal prism is 19 cm

The expression P2 = 100000(0.4)^(d - 4) is an illustration of an exponential expression
The equivalent expression of P2 = 100000(0.4)^(d - 4) is P2 = 3906250(0.4)^d
How to determine the equivalent equation?The equation is given as:
P2 = 100000(0.4)^(d - 4)
Apply the law on indices on the expression.
P2 = 100000(0.4)^d * 1/0.4^4
Rewrite as:
P2 = 1/0.4^4 * 100000(0.4)^d
Evaluate the exponent
P2 = 39.0625 * 100000(0.4)^d
Evaluate the product
P2 = 3906250(0.4)^d

The product of 2 consecutive even integers is 528 find the value of each integers
Answer :-
Value of two integers are 22 and 24Step-by-step explanation:
Given :-
The product of 2 consecutive even integers is 528To Find :-
Value of each integersSolution :-
Let one integer be xother integer be x + 2According to question,
Product of two integers = 528↠ (x)(x + 2) = 528
↠ x² + 2x = 528
↠ x² + 2x - 528 = 0
↠ x² + 24x - 22x - 528 = 0
↠ x(x + 24) - 22 (x + 24) = 0
↠ (x + 24) (x - 22) = 0
↠ x = -24 or 22
Hence,
1st integer = 222nd Integer = 22 + 2 = 24Value of two integers are 22 and 24
Step-by-step explanation:
It is given that, The product of 2 consecutive even integers is 528 and we have to find the value of each integers.
So, Let us assume the 1st consecutive even integer as y and the 2nd as (y + 2)Now, As it is stated in the question that the product of 2 consecutive even integers is 528, So
[tex] \\ { \longrightarrow \qquad{ \pmb{ \sf { y(y + 2) = 528 }}}} \: \: \\ \\[/tex]
[tex]{ \longrightarrow \qquad{ \pmb{ \sf { {y}^{2} + 2y = 528 }}}} \: \: \\ \\[/tex]

[tex]{ \longrightarrow \qquad{ \pmb{ \sf { {y}^{2} + 2y - 528= 0 }}}} \: \: \\ \\[/tex]

[tex]{ \longrightarrow \qquad{ \pmb{ \sf { p \times q= 528 }}}} \: \: \\ \\[/tex]
The two numbers are 24 and 22. So,
