Answer:
A and B
Step-by-step explanation:
Quadratic Equations: f(x) = a(bx - h)² + k
Quadratic equations always have a degree of 2. That means that we will always have an x² term. Of the 4 choices, only A and B offer a term of x², making them a quadratic.
Answer:
Y = 5x - 3/2 + x^2
Y = x^2 + 5x - 2
Step-by-step explanation:
The function must contain x^2.
That is have a degree of 2.

In Yakuna it was -13 degrees in the morning. The highest tempature was 29. Was was the total number the temp. increased
Answer:
42 degrees
Step-by-step explanation:
Use a number line.
-13 - 13 = 0.
Now, we are at the base, 0. Then, add 29.
13 + 29 + 42.
The answer is 42. Hope it helps!
What are the coordinates of point B on AC such that the ratio of AB to AC is 1:3
Answer:
B) (2/3, 3 2/3)
Step-by-step explanation:
I think whoever write this problem thought the distance from A to C was 10. It’s not. It’s 10.77. (See below). But following what they did, the answer must be B) (2/3, 3 2/3)
First, find the distance from A to C.
4²+10²=c²
16+100=c²
116=c²
c=√116
10=10.77
The coordinates of point B on AC such that the ratio of AB to AC is 1:3 is (2/3, 3 2/3) option (B) is correct.
What is a segment bisector?A segment bisector is a line, ray, line segment, or point that divides a line segment into two equal halves at its center.
It is given that:
The line segment shown in the picture is in the ratio of AB to AC is 1:3
AB : AC = 1 : 3
m : n = 1 : 3
The coordinate of point A is (2, 7)
The coordinate of point C is (-2, -3)
Let the coordinate of the point B is (x, y)
m = 1
n = 2
x1 = 2
x2 = -2
y1 = 7
y2 = -3
x = (-2+4)/3
x = 2/3
y = (-3+14)/3
y =11/3
y = 3 2/3
B = (x, y) = (2/3, 3 2/3)
Thus, the coordinates of point B on AC such that the ratio of AB to AC is 1:3 is (2/3, 3 2/3) option (B) is correct.
The options are:
A. (1/3, 2 5/6)
B. (2/3, 3 2/3)
C. (-2/3, 1 1/6)
D. (-2/3, 1/3)

Calculus (2) Master Needed to show steps of evaluating the integral b=0, a= pi/2 :[tex]\int\limits^a_b {(t^2-3t)sint} \, dt[/tex] I get stuck after applying integration by parts and simplified the negative, I get [tex](t^2-3t)*-cost |\frac{\pi /2}{0} + \int\limits^a_b {cost * (t-3)} \, dt[/tex] what am I supposed to do at this stage? Or did I do it wrong? Step by step is needed!
Answer:
[tex]\displaystyle \int\limits^{\pi/2}_ {0} \,(t^2-3t)\sin t\, dt = \pi -5[/tex]
Step-by-step explanation:
We want to evaluate the integral:
[tex]\displaystyle \int\limits^{\pi/2}_ {0} \,(t^2-3t)\sin(t)\, dt[/tex]
Since this is a product of two functions, we can use Integration by Parts. Recall that:
[tex]\displaystyle \int u\, dv = uv - \int v\, du[/tex]
Let u be t² - 3t and let dv be sin(t).
Thus:
[tex]du = 2t - 3\, dt[/tex]
And:
[tex]\displaystyle v = \int \sin t\, dt = - \cos t[/tex]
So:
[tex]\displaystyle =\left(-\cos t\right)\left(t^2-3t\right)\Bigg|_0^{\pi/2}-\int_{0}^{\pi/2} \left(-\cos t\right)\left(2t-3\right)\, dt[/tex]
Simplify:
[tex]\displaystyle = - \left(\cos t\right)(t^2-3t)\Bigg|_{0}^{\pi /2}+\int\limits^{\pi/2}_ {0} \,\cos(t)(2t-3)\, dt[/tex]
We can use IBP once more.
Let u be 2t - 3 and let dv be cos(t). Therefore:
[tex]du = 2\, dt[/tex]
And:
[tex]\displaystyle v = \int \cos t\, dt = \sin t[/tex]
So:
[tex]\displaystyle = - \left(\cos t\right)(t^2-3t)\Bigg|_0^{\pi/2}+\left(\sin(t)(2t-3)\Bigg|_0^{\pi /2}-\int\limits^{\pi/2}_0 \, 2\sin(t)dt \right)[/tex]
Evaluate:
[tex]\displaystyle =-\left(\cos t\right)(t^2-3t)+\sin(t)(2t-3)+2\cos(t)\Bigg|_0^{\pi /2}[/tex]
Evaluate the first section:
[tex]\displaystyle \begin{aligned} &= -\cos\left(\frac{\pi}{2}\right)\left(\left(\frac{\pi}{2}\right)^2-3\left(\frac{\pi}{2}\right)\right)+\sin\left(\frac{\pi}{2}\right)\left(2\left(\frac{\pi}{2}\right)-3\right)+2\cos \left(\frac{\pi}{2}\right)\right) \\ \\ &= (0) + (1)(\pi -3) + (0) \\ \\ &= \pi -3 \end{aligned}[/tex]
And the second:
[tex]\displaystyle \begin{aligned} &= -\cos(0)((0)^2-3(0))+(\sin(0))(2(0)-3)+2\cos(0 ) \\ \\&=(0)+(0)+(2) \\ \\ &= 2\end{aligned}[/tex]
Therefore:
[tex]\displaystyle \int\limits^{\pi/2}_ {0} \,(t^2-3t)\sin(t)\, dt = (\pi -3) -(2) = \pi -5[/tex]

9/8m - 1/6m = -4 - 11/3
Answer:
m=-8
Step-by-step explanation:
im assuming the equation is: [tex]\frac{9}{8} m-\frac{1}{6} m=-4-\frac{11}{3}[/tex]
find common denominators i choose 24
9/8 = 27/24
1/6 = 4/24
11/3 = 88/24
4 = 96/24
now start solving:
(Note that because denominators are the same you can just ignore them and focus on the numerator)
simplify (27/24)m - (4/24)m to (23/24)m
simplify -(96/24) - (88/24) to -184/24
now you are left with 23/24 m = -184/24
get rid of denominators 23m=-184
Divide -184 by 23 to get m= -8
if dm=50 what ia the value of r?

there are five united states athletes, four russian athletes, three french athletes, and one german athlete. How many rankings of the 13 athletes are there
Answer:
There are 6227020800 possible rankings
Step-by-step explanation:
Given
[tex]Athletes= 13[/tex]
Required
Number of Rankings
Let the number of athletes be n;
Since each athlete can only take one position at any given instance, the number of rankings is [tex]n![/tex]
Where [tex]n = 13[/tex]
Substitute 13 for n
[tex]13! = 13 * 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 *3 * 2 *1[/tex]
[tex]13! = 6227020800[/tex]
Hence, there are 6227020800 possible rankings
Liam wants to buy a lead for his guitar.
It must be longer than 7.59 m.
Lead Type Length
Lead A

Lead B
7.8 m
Lead C
8.3 m
Lead D
0.75 m
Answer:
B: 7.8m
Step-by-step explanation:
7.8m is 21cm more than 7.59m so it is close.
8.3 meters would be a bit too long for his lead.
solve the question x/-4 = 3/4 so 'x' is equal to?
Answer:

Step-by-step explanation:
[tex] \sf{ \frac{x}{ - 4} = \frac{3}{4} }[/tex]
Do cross multiplication
[tex] \dashrightarrow{ \sf{x \times 4 = 3 \times ( - 4)}}[/tex]
[tex] \dashrightarrow{ \sf{4x = - 12}}[/tex] ( Multiplying a positive integer and negative integer gives a negative integer )
Divide both sides of the equation by 4
[tex] \dashrightarrow{ \sf{ \frac{4x}{4} = \frac{ - 12}{4} }}[/tex]
Calculate

Bill has $6 more than Ted. Together they have $32. Write two equations and then solve for the amount of money that bill has.
Someone alr told me the was $19 but I NEED the equation part
Answer:
B= Bill's money
T= Ted's money
B+T=32
T+6=B
Step-by-step explanation:
If you rearrange the first equation you get:
B=32-T
You can then substitute the B in that equation with T+6:
T+6=32-T
combine like terms to get T:
2T+6=32
2T=26
T=13
Then plug in 13 for T in either of the first equations to get B:
13+6=B
19=B
Answer:
Bill has 19$
Step-by-step explanation:
Bill = b
Ted = t
b = t + 6$
b - t = 6$------equation 1
b + t = 32$------equation 2
(equation 1 - equation 2)
(b - b) + (-t - t) = 6 - 32
0 - 2t = -26
-2t = -26
t = -26/-2
t = -26/-2
t= 13$
(put t = 13$ in equation 1)
b - (13) = 6
b - 13 = 6
b = 6 + 13
b = 19$ (Bill = 19$)

Point M is the midpoint of FG. Can the value of variable a be determined? Explain F(b+1, a+2). M(3,5). G(2a, 3b+3)
Answer:
YES, the value of a is 2Step-by-step explanation:
Given the coordinates F(b+1, a+2, M(3,5) and G(2a, 3b+3), if M is the midpoint of F and G then, to get the value of a and b we will use the formula for calculating the midpoint a shown;
M(X, Y) = (x₁+x₂/2, y₁+y₂/2)
X = x₁+x₂/2 and Y = y₁+y₂/2
From the given coordinates x₁ = b+1, y₁ = a+2, x₂ = 2a, y₂ = 3b+3, X = 3 and Y = 5
Substituting the given parameters into the formula, we can get the value of a and b as shown;
3 = b+1+2a/2
6 = 2a+b+1
2a+b = 5 ............... 1
Similarly, for the Y coordinate;
5 = a+2+3b+3/2
10 = a+2+3b+3
a+3b = 10-2-3
a+3b = 5 ........ 2
Solving equation 1 and 2 simulatneously using elimination method
2a+b = 5 ............... 1 * 1
a+3b = 5 ........ 2 * 2
---------------------------------------------------------
2a+b = 5 ...........3
2a +6b = 10.......... 4
subtract 3 from 4
b - 6b = 5-10
-5b = -5
b = -5/-5
b = 1
substitute b =1 into equation 2 to get a;
a + 3b = 5
a + 3(1) = 5
a = 5-3
a = 2
From the calculation above it is seen that the value of variable a can be determined and it is equivalent to 2
Answer:
To determine the value of a, set up and solve a system of equations in two variables. The value of a is 2
