A boy pulls a wagon a distance of 1.2 km. An applied force of 22N is directed at an angle of 25 degrees above the horizontal. How much work is done?
Answer: 23.92 kJ
Step-by-step explanation:
Given
Distance moved by wagon is [tex]d=1.2\ km[/tex]
Force [tex]F=22\ N[/tex] directed at an angle of [tex]25^{\circ}[/tex] above the horizontal
Only the horizontal component of the force that is, [tex]22\cos 25^{\circ}[/tex]the wagon will cause the wagon to move, while the other force is perpendicular to the wagon and thus produce zero displacements.
Work done is
[tex]W=F\cdot s\\W=22\times 1.2\times 10^3\times \cos 25\\W=23.92\ kJ[/tex]
thus, 23.92 kJ of work is done on the wagon.
240% of what number is 360? +
Answer:
240% of 150 is 360
Step-by-step explanation:
240% of [tex]x[/tex] = 360
[tex]\frac{240}{100}[/tex] x [tex]x[/tex] = 360
2.4 [tex]x[/tex] = 360
[tex]x[/tex] = [tex]\frac{360}{2.4}[/tex]
[tex]x[/tex] = 150

Angelique makes beaded jewelry. The graph below shows the number of beads on varying cord lengths. Jewelry  A necklace contains 88 beads. Based on the information above, which is the best estimate for the cord length? 21 inches 26 inches 34 inches 36 inches.
Answer:
please show answer choices
Step-by-step explanation:
Find the common difference of the arithmetic sequence -2,6,14,...
Lets note the change between each of the numbers in the sequence:
-2 --> 6 ---> 14
Next, make an equation between each of these numbers with x being the change between them
-2+ x = 6, 6 + x = 14 .
Now, solve each of these equations:
-2+ x = 6 --> -2+ x = 6 Add 2 on both sides to cancel out the -2 --> x = 8
6+ x = 14 --> -2+ x = 6 Minus 6 on both sides to cancel out the 6 --> x = 8
From this, the common difference will be 8.
Hope that helps.

Chuck has 20 feet of fencing and wishes to make a rectangular fence for his dog Rover. If he uses his house for one side of the fence what is maximum area?
Answer:
50 square feet.
Step-by-step explanation:
Let x represent the width of the fence and y represent the length of the fence.
One side of the length is already covered by the house. This leaves 2x and y. This must sum to 20. Hence:
[tex]2x+y=20[/tex]
The area of the enclosure will be given by:
[tex]A=xy[/tex]
From the first equation, we can subtract 2x from both sides:
[tex]y=20-2x[/tex]
Substitute:
[tex]A=x(20-2x)[/tex]
This is now a quadratic. Recall that the maximum value of a quadratic always occurs at its vertex. So, find the vertex of the equation. Distribute:
[tex]A=20x-2x^2[/tex]
In this case, a = -2, b = 20, and c = 0.
Hence, the vertex is:
[tex]\displaystyle x=-\frac{b}{2a}=-\frac{(20)}{2(-2)}=5[/tex]
Substitute this value back into the equation and evaluate:
[tex]A(5)=20(5)-2(5)^2=50\text{ ft}^2[/tex]
The maximum area is 50 square feet.
This occurs when the dimensions are 5 feet by 10 feet.

the first term of an arithmetic sequence is 10 and the sum of the first five terms is 250,find the sequence
Answer:
The sequence is:
10, 30, 50, 70, 90.....................
Step-by-step explanation:
We have,
First term (a) = 10
Common difference (d) = ?
Sum of first 5 terms ([tex]S_{5}[/tex]) = 250
or, [tex]\frac{n}{2} [{2a+(n-1)d}] = 250[/tex]
or, [tex]\frac{5}{2} [2*10 + 4d]=250[/tex]
or, [tex]\frac{5}{2} * 4[5+d]=250[/tex]
or, 10(5 + d) =250
or, 5 + d = 25
∴ d = 20
Now,
2nd term = a + d = 10 + 20 = 30
3rd term = a + 2d = 10 + 2*20 = 10 + 40 = 50
4th term = a + 3d = 10 + 3*20 = 10 + 60 = 70
5th term = a + 4d = 10 + 4*20 = 10 + 80 = 90

How would I figure out a linear equation with two plot points with fractions? (1/3(6),3) and (1/2(19),-2) are my two plot points. I was able to graph them on Desmos, but I can't seem to figure out how I would go about figuring out the slope and y-intercept in this case... the fractions are what's throwing me off here. Please help!
Answer: [tex]m=\frac{-30}{79},\ y=5.40[/tex]
Step-by-step explanation:
Given
Points are [tex]\left(6\frac{1}{3},3\right),\ \left(19\frac{1}{2},-2\right)[/tex]
Convert mixed numeral to fraction
[tex]\left(6\frac{1}{3},3\right)\Rightarrow \left(\dfrac{19}{3},3\right)\\\\\left(19\frac{1}{2},-2\right)\Rightarrow \left(\dfrac{39}{2},-2\right)[/tex]
Slope of the line is
[tex]\Rightarrow m=\dfrac{3-(-2)}{\dfrac{19}{3}-\dfrac{39}{2}}\\\\\Rightarrow m=\dfrac{5}{\dfrac{38-117}{6}}\\\\\Rightarrow m=\dfrac{-30}{79}[/tex]
Equation of line
[tex]\Rightarrow \dfrac{y-3}{x-\dfrac{19}{3}}=\dfrac{-30}{79}\\\\\text{for y-intercept, put x=0}\\\\\Rightarrow \dfrac{y-3}{0-\dfrac{19}{3}}=\dfrac{-30}{79}\\\\\Rightarrow y-3=\dfrac{190}{79}\\\\\Rightarrow y=3+2.40\\\Rightarrow y=5.40[/tex]
The probability distribution for a random variable x is given in the table

Answer:
[tex]P(-2 \le x \le 2) =0.60[/tex]
Step-by-step explanation:
Given
[tex]\begin{array}{ccccccc}x & {-5} & {-3} & {-2} & {0} & {2} & {3} \ \\ P(x) & {0.17} & {0.13} & {0.33} & {0.16} & {0.11} & {0.10} \ \end{array}[/tex]
Required
[tex]P(-2 \le x \le 2)[/tex]
From the distribution, the above is equivalent to:
[tex]P(-2 \le x \le 2) =P(x = -2) +P(x = 0)+P(x = 2)[/tex]
We have:
[tex]P(x = -2) = 0.33[/tex]
[tex]P(x = 0)=0.16[/tex]
[tex]P(x = 2) = 0.11[/tex]
So:
[tex]P(-2 \le x \le 2) =P(x = -2) +P(x = 0)+P(x = 2)[/tex]
[tex]P(-2 \le x \le 2) = 0.33 + 0.16 +0.11[/tex]
[tex]P(-2 \le x \le 2) =0.60[/tex]

Q7. What is the equation of the system of equations below? Explain how
you arrived at your answer
W
18x + 15-y-0
5y - 90x + 12
Answer: 18x -15 -y =0
Step-by-step explanation:
because linear equations in two variables are always in the format of ax+by+c=0
where a,b and c are constant terms
in this case a = 18; ax= 18x
b= -1 , by= -y
c= 15
Answer:
90x + 75 = 90x + 12, they don't intersect
Step-by-step explanation:
18x + 15 - y = 0
5y = 90x + 12
1. We will be using substitution, to do so, bring y to the other side in the first eqaution.
18x + 15 - y = 0
18x + 15 = y
2. Now plug in 18x+15 into the second equation
5(18x + 15) = 90x + 12
3. Distribute and solve for x
90x + 75 = 90x + 12
Because the slopes are the same (90x) this means that the system does not have an intersect.
