Answer:
x = 17
Step-by-step explanation:
5x - 18 and 4x + 45 are adjacent angles on as straight line and sum to 180° , so
5x - 18 + 4x + 45 = 180 , that is
9x + 27 = 180 ( subtract 27 from both sides )
9x = 153 ( divide both sides by 9 )
x = 17

Step-by-step explanation:
This season, the Jays won eight fewer games than the Hawks. The Jays won 33 games. Choose the equation you could use to find the number of games the Hawks won.
33 – h = 8
33 = h – 8
h + j = 33
h + 33 = 8
Answer:
33=h-8
Step-by-step explanation:
33= h-8 add 8 on both sides to solve for h
+8 +8
41= h The hawks won 41 games.
Find the circulation done by the velocity field V(x,y)= -y/[(x+1)^2 +4y^2]i + (x+1)/[(x+1)^2 +4y^2]j around the positively oriented square with vertices (2, 0), (0, 2), (−2, 0), and (0, −2).
The circulation of V around the given path (call it C) is simply the line integral of V along C. Since C is a closed curve, we can use Green's theorem.
[tex]\displaystyle \int_C \vec V(x,y) \cdot d\vec r = \iint_{\mathrm{int}(C)} \frac{\partial}{\partial x}\left[\frac{x+1}{(x+1)^2+4y^2}\right] - \frac{\partial}{\partial y}\left[-\frac{y}{(x+1)^2+4y^2}\right] \, dx\,dy[/tex]
where int(C) is the interior or region bounded by C.
We have
[tex]\dfrac{\partial}{\partial x}\left[\dfrac{x+1}{(x+1)^2+4y^2}\right] = \dfrac{4y^2 - (x+1)^2}{((x+1)^2+4y^2)^2}[/tex]
[tex]\dfrac{\partial}{\partial y}\left[-\dfrac{y}{(x+1)^2+4y^2}\right] = \dfrac{4y^2-(x+1)^2}{((x+1)^2+4y^2)^2}[/tex]
so the double integral and hence the circulation is zero.

which statement is false?
every real number is also rational
Answer:
The statement "Every real number is also rational" is FALSE.
Step-by-step explanation:
Natural numbers, Whole numbers, Rational numbers and Irrational numbers are all real. Imaginary and Complex numbers are not Real (yes, this is an actual math thing.)
So you may have an Irrational number such as pi or sqroot(7) that are Real but not Rational. This proves the statement is FALSE. (counter-example)
2c – 4 = 3(4 – 2c)
please find c
Answer:
c = 2
Step-by-step explanation:
2c – 4 = 3(4 – 2c)
Expand brackets:
⇒ 2c – 4 = 12 - 6c
Add 6c to both sides:
⇒ 8c – 4 = 12
Add 4 to both sides:
⇒ 8c = 16
Divide both sides by 8:
⇒ c = 2
Answer:
c = 2
Step-by-step explanation:
First expand 3(4-2c):
3×4=12
3×-2c=-6c
Now our equation is :
2c-4 = 12-6c
Add 4 to both sides:
2c-4+4=12-6c+4
Simplify:
2c = -6c+16
Add 6c to both sides:
2c+6c = -6c+16+16
Simplify:
8c=16
Divide both sides by 8:
8c÷8 = 16÷8
c = 2

Finding the value for a new score that will yield a given mean
Heather has scored 74, 74, and 83 on her previous three tests. What score does she need on her next test so that her average (mean) is 74
Answer:
Step-by-step explanation:
The mean in this case is calculated by adding all the scores up divided by the number of scores, in that case, we get the equation:
[tex]\frac{74+74+83+x}{4} = 74[/tex] , where x is the score she needs to get
x = 65
Thus the score she needs to get on her next test is 65.

2. Find the stationary points for the function
[tex]y = \frac{1}{3} {x}^{3} - \frac{1}{2} {x}^{2} - 6x + 7[/tex]
and determine the nature of each points by using the second derivative test.
Answer & step-by-step explanation:
Stationary points are the points where the first derivative is equal to zero.
Let's calculate it using the power rule (exponent comes forward, decrease exponent by 1) and the fact that the derivative is a linear operation (that is [tex]D[a\ f(x) + b\ g(x)] = a Df(x) + b Dg(x)[/tex])
The first derivative is then
[tex]y' = \frac13 (3x^2) - \frac12 (2x) -6 = x^2-x-6 = (x+2)(x-3)[/tex]
Note that the last passage is not strictly needed, but it's really helpful to find stationary points, when in this next passage we set it equal to zero. Alternatively, you can use the quadratic formula if you can pull the factors out of your head right away.
[tex]y'=0 \rightarrow (x+2)(x-3) = 0 \implies x=-2 || x=3[/tex]
These two point could be maxima, minima, or inflection points. To check them you can either see how the sign of the first derivative goes, or check the sign of the second derivative, as you're required.
The rules states that if the second derivative evaluated in that point is negative we have a maximum, if it's positive we have a minimum, and if we have a zero we keep derivating until we get a non-zero value.
In our case, the second derivative we get by calculating the derivative again and we get [tex]y'' = 2x-1[/tex] . Evaluating it at both points we get
[tex]y''(-2) = 2(-2)-1 = -5\\y''(3) = 2(3) -1 = 5[/tex]
so -2 is a maximum and 3 is a minimum.
Answer:
[tex]\left( 3, -\dfrac{13}{2} \right) \textsf{minimum}[/tex]
[tex]\left( -2, -\dfrac{43}{3} \right)\textsf{maximum}[/tex]
Step-by-step explanation:
To find the stationary points, differentiate, set to zero, and solve for x. Input found values of x into original equation to find y-coordinates.
[tex]y=\dfrac13x^3-\dfrac12x^2-6x+7[/tex]
[tex]\implies \dfrac{dy}{dx}=3\cdot \dfrac13x^{(3-1)}-2 \cdot \dfrac12x^{(2-1)}-6x^{(1-1)}+7\cdot0[/tex]
[tex]\implies \dfrac{dy}{dx}=x^2-x-6[/tex]
[tex]\dfrac{dy}{dx}=0[/tex]
[tex]\implies x^2-x-6=0[/tex]
[tex]\implies (x-3)(x+2)=0[/tex]
[tex]\implies x=3, x=-2[/tex]
[tex]\textsf{at }x=3: y=\dfrac13(3)^3-\dfrac12(3)^2-6(3)+7=-\dfrac{13}{2}[/tex]
[tex]\textsf{at }x=-2: y=\dfrac13(-2)^3-\dfrac12(-2)^2-6(-2)+7=\dfrac{43}{3}[/tex]
To determine the nature of each point, differentiate again, input found values of x into the second derivative. If positive then minimum point, if negative then maximum point.
[tex]\dfrac{d^2y}{dx^2}=2 \cdot x^{(2-1)}-x^{(1-1)}-6 \cdot0[/tex]
[tex]\implies \dfrac{d^2y}{dx^2}=2x-1[/tex]
[tex]\textsf{at }x=3:\dfrac{d^2y}{dx^2}=2(3)-1=5 > 0\implies \textsf{minimum}[/tex]
[tex]\textsf{at }x=-2:\dfrac{d^2y}{dx^2}=2(-2)-1=-5 < 0\implies \textsf{maximum}[/tex]

A boat’s velocity, measured in meters per second, is described by vector b⇀=⟨3,4⟩. In two or more complete sentences explain how to find the speed of the boat and the direction it is traveling in standard position. In your final answer, include all of your calculations.
for this i got 5 m/s and 413 but i need to know more about it. i have to factor in WHERE the vector is before calculating the direction- and i dont quite understand how to do that so help would be MUCH appreciated <3
Answer: Velocity is a vector, so it has a magnitude and direction.
Speed is its magnitude, which is obtained from
|〈-3, 4〉 m/s| = √((-3 m/s)² + (4 m/s)²) = √(25 m²/s²) = 5 m/s
Its direction is an angle θ made with the positive horizontal axis, satisfying
tan(θ) = (4 m/s) / (-3 m/s) = -4/3 → θ = arctan(-4/3) + 180°n
where n is any integer. Now you have to consider that the x coordinate is negative and the y coordinate is positive, so 〈-3, 4〉 points into the second quadrant, and we get an angle there for n = 1 of about
θ ≈ 126.87°
Alternatively, you can use the vector 〈1, 0〉 in place of the axis, then compute the angle by relating it to the dot product, so θ is such that
〈-3, 4〉 • 〈1, 0〉 = |〈-3, 4〉| |〈1, 0〉| cos(θ)
(-3)•1 + 4•0 = √((-3)² + 4²) • √(1² + 0²) cos(θ)
-3/5 = cos(θ) → θ = arccos(-3/5) + 360°n
where again, n is any integer, and we get the same solution θ ≈ 126.87° in the second quadrant when n = 0.

The Walker Vikings points scored per game for their basketball games this season were:
Home: 90,87,86,81,93,78,49,94,69,82,80; Mean points scored per game: ≈ 80.8 Standard deviation of ≈ 12.2 Away: 64,72,67,84,65,71,57,69,59,58,68; Mean points scored per game: ≈ 66.7 Standard deviation of ≈ 7.3. What is the correct conclusion?
A) At away games, the Vikings were more consistent and on average scored more points.
B) At home games, the Vikings were more consistent and on average scored more points.
C) The Vikings averaged more points at away games, but were more consistent when playing at home.
D) The Vikings averaged more points at home games, but were more consistent when playing on the road.
A correct conclusion that can be reached is that: D) The Vikings averaged more points at home games, but were more consistent when playing on the road.
What is an arithmetic average?An arithmetic average is also referred to as mean and it can be defined as a ratio of the sum of the total number in a data set (population) to the frequency of the data set.
This ultimately implies that, an average score is a mean score and it can be calculated by dividing the total number of scores obtained by the total number of Vikings players.
In conclusion, we can reasonably infer and logically deduce that Walker Vikings were more consistent when playing on the road, but averaged more points at home games.

Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. The correct option is D, 38 millon.
What is compounding?Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. and this continues for t period of time.
It is given by the formula,
A = P(1+r)ⁿ
where, A is the value after n period of time, P is the initial amount, and,
r is the rate of increment or decrement.
Given that On the first day of a song's release, it had 20 million streams. Also, the number of streams increases by 10% per day. Therefore, it can be said that the number of streams is compounding. Thus, the number of streams on the seventh day will be,
Number of streams = 20 (1+0.10)⁷ million
= 20 × 1.9487 million
= 38.974 million
= 38 million
Hence, the number of streams there will be on the seventh day is 38 million.
