S = 6t² + 3t + 7, 0 ≤ t ≤ 2 Find the body's displacement and average velocity for the given time interval. A) 30 m, 30 m/sec B) 44 m, 22 m/s C) 18 m / sec , 27 m /sec D) 30 m / sec , 15 m /sec
Answer:
30m, 24m/s
Step-by-step explanation:
Given the expression for the position of the object expressed as:
S = 6t² + 3t + 7,
At t = 0
S0 = 6(0)²+3(0)+7
S0 = 0+0+7
S(0) = 7m
At t = 2
S2 = 6(2)² + 3(2)+ 7
S2 = 6(4)+6+7
S2 = 24+13
S2 = 37
The displacement = S2-S0 = 37-7= 30m
For the velocity
V = dS/dt = 12t+3
At t = 0
V0 = 12(0)+3
V0 = 3
At t= 2
V2 = 12(2)+3
V2 = 24+3
V2 =27
The velocity will be V2-V0 = 27-3 = 24m/s

What is the value of [3.6]
A: 3
B: 3.5
C: 3.6
D: 4
Answer: 3
Step-by-step explanation: [ 3.6 ] represents the greatest integer function [ x ]
If x is an integer use that integer
If x is not an integer use the next smaller integer
[ 3.6 ] is not an integer, hence
[ 3.6 ] = 3

You must determine the volume of air flowing through a duct. Begin by determining the area of the duct. (In a later step, you would multiply that value by the speed of
the air flowing through the duct to determine air volume.) The diameter of the round air duct is 16 inches. What is the area of its circular opening to the nearest whole
number?
The area of the circular opening is 16 square inches.
Answer:
4 i think
Step-by-step explanation:
The area of the circular opening is 201.14 sq.inches.
What is Area ?Area is the space occupied by any given surface in a two dimensional plane.
A circular duct has a diameter of 16 inches
Area of the circular opening is given by
πd²/4
d is the diameter of the circle
= (22/7) * (16)²/4
= 201.14 sq.inches
Therefore the area of the circular opening is 201.14 sq.inches.

I think of a number. I subtract 4,then divide by 5. The result equals 15.
a) Write this information in the form of an equation.
b) Solve the equation to find the number I was thinking of.
Answer:
a) (X - 4)x 5 = 15
b) the answer is 7
Step-by-step explanation:
divide 15 by 5 and then add 4, do the equasion backwards :)
The solution of the given equation (X - 4)x 5 = 15 would be equal to 7.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Now we will try solving it first using the method of substitution in which we express one variable in other variable's form and then you can substitute this value in other equation to get linear equation in one variable.
We are given that a number subtract 4, then divide by 5. The result equals 15.
a) The equation form as
(X - 4)x 5 = 15
b) Now solving the equation as;
(X - 4)x 5 = 15
5x - 20 = 15
x = 35/7
x = 7
Hence, the answer is 7

Question # 7
Given two points
(0, 0)(3, 3)Determining the slope of the line passing through the points (0, 0) and (3, 3)
(x₁, y₁) = (0, 0)
(x₂, y₂) = (3, 3)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [3 - 0] / [3 - 0]
= 3 / 3
= 1
Thus, the slope of the line = m = 1
Question # 8
Given two points
(1, 3)(5, 5)Determining the slope of the line passing through the points (1, 3) and (5, 5)
(x₁, y₁) = (1, 3)
(x₂, y₂) = (5, 5)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [5 - 3] / [5 - 1]
= 2/4
= 1/2
Thus, the slope of the line = m = 1/2
Question # 9
Given two points
(4, 4)(5, 3)Determining the slope of the line passing through the points (4, 4) and (5, 3)
(x₁, y₁) = (4, 4)
(x₂, y₂) = (5, 3)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [3 - 4] / [5 - 4]
= -1 / 1
= -1
Thus, the slope of the line = m = -1
A sporting goods store sells right-handed and left-handed baseball gloves. In one month, 12 gloves were sold for a total revenue of $561. Right-handed gloves cost $45 and left-handed gloves cost $52. How much of each type of gloves did they sell
Answer:
[tex]9[/tex] right-handed gloves and [tex]3[/tex] left-handed gloves were sold.
Step-by-step explanation:
Given: In one month, [tex]12[/tex] gloves were sold for a total revenue of [tex]\$561[/tex].
right-handed gloves cost [tex]\$45[/tex] and left-handed gloves cost [tex]\$52[/tex].
To find: How much of each type of gloves did they sell?
Solution: Let they sell [tex]x[/tex] right-handed gloves, and [tex]y[/tex] left-handed gloves.
Now, cost of each right-handed gloves [tex]=\$45[/tex]
cost of each left-handed gloves [tex]=\$52[/tex]
Total revenue [tex]=\$561[/tex]
So, we get
[tex]45x+52y=561\:\:\:...(i)[/tex]
Also, in a month [tex]12[/tex] gloves were sold.
So, we get
[tex]x+y=12\:\:\:...(ii)[/tex]
Now, from [tex](ii)[/tex] we get, [tex]x=12-y[/tex].
Putting [tex]x=12-y[/tex] in equation [tex](i)[/tex], we get
[tex]45(12-y)+52y=561[/tex]
[tex]\implies 540-45y+52y=561[/tex]
[tex]\implies7y=561-540[/tex]
[tex]\implies7y=21[/tex]
[tex]\implies y=\frac{21}{7}[/tex]
[tex]\implies y=3[/tex]
Now, putting [tex]y=3[/tex] in equation [tex](ii)[/tex], we get
[tex]x+3=12[/tex]
[tex]\implies x=12-3[/tex]
[tex]\implies x=9[/tex]
Hence, [tex]9[/tex] right-handed gloves and [tex]3[/tex] left-handed gloves were sold.

Find the equation of the line which passes through (2,4) with a slope of 1/2
Answer: the answer is y=1/2x+3
Step-by-step explanation:
Hopes this helps !! Message me if explanation is needed !!!
The equation of the line which passes through (2,4) with a slope of 1/2 is [tex]y = \frac{x}{2} +3[/tex].
What is a slope-intercept form?Y = mx + b is the slope-intercept form of the equation of a straight line. In the equation y = mx + b, m is the slope of the line and b is the intercept. X and y represent the distance of the line from x-axis and y-axis, respectively. The value of b is equal to y when x = 0, and m shows how steep the line is.
Given
Slope m = 1/2
Point (x, y) = (2, 4)
Equation of line which passes through a point (x, y) with a slope of m is
y = mx + b
Substitute the values
⇒ [tex]4=\frac{1}{2}(2)+b[/tex]
⇒ 4 = 1 + b
⇒ b = 4 - 1
⇒ b = 3
Substitute m = 1/2 and b = 3 in equation (1)
[tex]y = \frac{1}{2}(x) +3[/tex]
⇒ [tex]y = \frac{x}{2} +3[/tex]
Hence, the equation of the line which passes through (2,4) with a slope of 1/2 is [tex]y = \frac{x}{2} +3[/tex].

bob is twice as old as ralph. three years ago the sum of their ages was 45. what are their ages now?
answer using a let statement
Answer:
Were they both 45? I'm kinda confused on that part, but I think Ralph would be 48 and Bob would be 50
Step-by-step explanation:
Answer:
34 and 17
Step-by-step explanation:
Bob = B
Ralph = R
B=2R
B-3+R-3=45
B+R-6=45
+6 +6
B+R=51
Substitute B for 2R
2R+R=51
3R=51
R=17
2(17)=34
so B is 34 and R is 17
