A plane flying with an air speed of 300 mph at 50 degrees and it crosses the jet stream, which is blowing at 200 mph at an angle of 160 degrees. The plane's actual velocity with respect to the ground is the vector sum of these two velocities. Find the actual velocity to the nearest whole mph and degree (add the sum of the vectors).
Answer:
298.24 mph at an angle of 89 degrees
Step-by-step explanation:
[tex]v_p[/tex] = Velocity of plane = 300 mph at 50 degrees
[tex]v_j[/tex] = Velocity of jet stream = 200 mph at 160 degrees
The velocity of the plane in component form is
[tex]v_p=300\cos50^{\circ}\hat{i}+300\sin50^{\circ}\hat{j}[/tex]
The velocity of the jet stream in component form is
[tex]v_j=200\cos160^{\circ}\hat{i}+200\sin160^{\circ}\hat{j}[/tex]
Resultant velocity is given by
[tex]v=(300\cos50^{\circ}+200\cos160^{\circ})\hat{i}+(300\sin50^{\circ}+200\sin160^{\circ})\hat{j}\\\Rightarrow v=4.9\hat{i}+298.2\hat{j}[/tex]
Magnitude is given by
[tex]|v|=\sqrt{4.9^2+298.2^2}\\\Rightarrow |v|=298.24\ \text{mph}[/tex]
Angle is given by
[tex]\theta=\tan^{-1}\dfrac{298.2}{4.9}=89^{\circ}[/tex]
The velocity of the plane is 298.24 mph at an angle of 89 degrees.

What is the equation of the line that passes through the coordinates (-2, 11) and (1, -34)?
Answer:
y = 15x - 19
Step-by-step explanation:
In order to pass through both (-2, 11) and (1, -34), then the equation must be y = 15x - 19. Hope this helps!

8 x 1/10
8 x 1/100
eight hundredths
Answer:
0.08, 8 hundreths, 8 x 1/100
Step-by-step explanation:
The first digit before the decimal is a unit.
The first digit after the decimal point is called a tenth
The second digit after the decimal point is called hundreths
The third digit after the decimal point is called a thousandths
The 8 is the second digit after the decimal point.
Therefore the answer is eight hundreths or represented by the decimal form of 0.08
It is also 8 x 1/100 because if we multiply this we get 0.08
Find the product of 12 and 8. Find the greatest common factor of 12 and 8. Find the least common multiple of 12 and 8. Find the product of the greatest common factor and the least common multiple of 12 and 8.
Answer:
Product: 96
GCF: 4
LCM: 24
Product of the GCF and LCM: 96
Step-by-step explanation:
Product - The answer to a multiplication problem.GCF - The greatest positive integer that evenly divides both numbers.LCM - The smallest multiple that both numbers have in common.Now that we know what definitions are, we can solve this word problem.
12 × 8 = 96.
96 is the product.
To find the greatest common factor, we can list all of the factors for each number.
12: 1, 2, 3, 4, 6, 12
8: 1, 2, 4, 8
The largest factor both numbers have in common is 4.
Therefore, 4 is the greatest common factor.
To find the least common multiple, we can list the multiples of both numbers.
12: 12, 24, 36, 48, 60, 72, 84, 96
8: 8, 16, 24, 32, 40, 48, 56, 64
The smallest multiple both numbers have in common is 24.
Therefore, 24 is the least common multiple.
Lastly, we have to find the product of the GCF and the LCM.
The GCF is 4 and the LCM is 24.
4 × 24 = 96.
96 is the product.
Therefore, 96 is the product of the greatest common factor and the least common factor of 12 and 8.
Factoring can be used to solve ANY quadratic equation.
True or false
Answer: False, Quadratic can sometimes be solved by factoring. It can ALWAYS be solved using the quadratic formula.
Step-by-step explanation:
Hope this helps :)
Answer:
false
Step-by-step explanation:
A quadratic equation is shown below: x2 − 8x + 13 = 0 Which of the following is the first correct step to write the above equation in the form (x − p)2 = q, where p and q are integers? (5 points) Subtract 5 from both sides of the equation Subtract 3 from both sides of the equation Add 5 to both sides of the equation Add 3 to both sides of the equation
Answer:
Add 3 to both sides of the equation
Solution:
The first step is to basically realize that all it's asking you to do is to find a way to make the expression on the left ([tex]x^2 - 8x + 13[/tex]) into an expression that is a perfect square. So what number should you add to both sides such that [tex]x^2 - 8x + (13 + j)[/tex] can be factored into [tex](x-p)^2[/tex] ? Well, we can approach it like this:
Since [tex](x-p)^2[/tex] can be turned into [tex]x^2 -2px + p^2[/tex], and our original form was [tex]x^2 - 8x + (13 + j)[/tex], we quickly realize that [tex]-2px = -8x[/tex]. From there, we can easily tell that [tex]p = 4[/tex]
Plug this into our last value [tex]p^2[/tex] to get 16. Therefore, if we compare this with our original equation again [tex]x^2 - 8x + (13 + j)[/tex], we notice that 13 + j = 16.
Thus, j = 3 for the last answer.
Add 3 to both sides of the equation.
Note: With more practice, you will quickly gain enough intuition to notice that [tex]x^2 - 8x + 13[/tex] is very close to [tex]x^2 - 8x + 16[/tex] which can be factored into [tex](x-4)^2[/tex]. But for now, the solution above will suffice. I hope this helps :))

Complete the square to write each equation in vertex form. Then, state whether the vertex is a minimum or a maximum and give its coordinates.
Answer:
a) y(x) = (x + 2)^2 -2
b) minimum
c) (-2, -2)
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
• If a > 0 then vertex is minimum
• If a < 0 then vertex is maximum
Given
y = x² + 4x + 2
(a)
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² + 4x
y = x² + 2(2)x + 4 - 4 + 2
y = (x + 2)² - 2
(b)
Since a = 1 > 0 then vertex is minimum
(c)
(h, k ) = (- 2, - 2 ) ← coordinates of vertex

If h = 18 units and r = 9 units, then what is the volume of the cone shown above
A. 234 cubic units
B. 1,458 cubic units
C. 972 cubic units
D. 486 cubic units
Answer:
Volume = 1526.04 cubic units
Step-by-step explanation:
Formula for volume of a cone:
V = πr²h/3
If we use 3.14 for pi, we get 1526.04:
V = 3.14(9)^2(18)/3
V = 1526.04

What is the distance apart (-6, -4.7) and (-6, 4.1)
Answer:
8.8
Step-by-step explanation:
Normally, to find the distance between two points, you would use the distance formula, but these two points have the same x-coordinate, meaning they will form a vertical line when connected. To find the length of a vertical line you find the distance between the y-coordinates, in this case -4.7 and 4.1. Finding the distance is the same as finding the absolute value of the difference:
|4.1 -(-4.7)|
|4.1 + 4.7|
|8.8|
8.8
