Order the polynomial -x 4 y 2 + 7x 3 y 3 - 3xy 5 + 2x 2 y 4 in descending powers of x.
Answer:
See under for the sequence
Step-by-step explanation:
The term with -X⁴ comes first because 4 is the highest power of x.
Then comes 7x³y³ because 3 is the second highest power
Then 2x²y⁴ because 2 comes next
Then -3xy⁵ because x is raised to 1 power which is the lowest

in the linear equation y= 3/4x + 2 what does 2 represent?
Answer: The y intercept.
Step-by-step explanation:
Using the form y = mx +b, m represents the slope and b is the y intercept. In the equation y = 3/4x + 2, the slope (m) = 3/4 and the y intercept (b) = 2

Answer:
Graph F best represents the function.
The correct graph F is also attached below.
Step-by-step explanation:
Given the function
f(x) = 2(5)ˣ
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
so substituting x = 0 in the function
y = 2(5)ˣ
y = 2(5)⁰
y = 2(1) ∵ (5)⁰ = 1
y = 2
Thus, the y-intercept is (0, 2)
Let us check another point
now substitute x = 1
y = 2(5)ˣ
y = 2(5)¹
y = 10
Thus, the value of y = 10 at x = 1
So, we have to two points:
The y-intercept (0, 2)The point (1, 10)Now, if we carefully observe, we can easily figure out that the graph F represents the function f(x) = 2(5)ˣ.
Because the graph F has a y-intercept (0, 2) and also the point (1, 10) is validating the graph.
Therefore, graph F best represents the function.
The correct graph F is also attached below.
Find an example of two irrational numbers a and b for which a≠b and a/b is rational.
Answer:
Yes.
Here’s an easy (and cheap) one: [tex]\\\\\sqrt 2\\-\sqrt 2[/tex]
In fact, I can find a formula for them.
The two numbers will always be of the form:
[tex]x_1 =a+b\sqrt c \\x_2 =a-b\sqrt c \\[/tex]
A and B are rational
C is rational and not a perfect square of a rational number
These are irrational because the square root will not resolve to a rational number.
12=(+√)(−√)=2−(√)2=2−2 . Looks rational to me.
1+2=+√+−√=2 , which also is rational.
Hope this helped!
Write an equation of a line in slope-intercept form that passes through (-3,5) and is parallel to y = -6x +1.
Then find its x- and y-intercepts.
Answer:
a) The equation of the Parallel line to the given straight line is
6 x + y + 13 =0
b) Slope - intercept form
y = - 6 x - 13
c) The intercept - form
[tex]\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1[/tex]
x - intercept = [tex]\frac{-13}{6}[/tex]
y - intercept = - 13
Step-by-step explanation:
Step(i):-
Given the equation of the straight line
y = -6x +1
6 x + y - 1 = 0
The equation of the Parallel line to the given straight line is
6x + y + k=0 and it passes through the point (-3, 5 )
⇒ 6 (-3 ) + 5 + k =0
⇒ - 18 + 5 + k=0
⇒ -13 + k = 0
⇒ k = 13
The equation of the Parallel line to the given straight line is
6 x + y + 13 =0
Step(ii):-
Slope - intercept form
y = m x + C
y = - 6 x - 13
Step(iii):-
Intercept - form
6 x + y + 13 =0
6 x + y = - 13
[tex]\frac{6x + y}{-13} = \frac{-13}{-13}[/tex]
[tex]\frac{6x}{-13} + \frac{y}{-13} = 1[/tex]
[tex]\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1[/tex]
The intercept - form
[tex]\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1[/tex]
x - intercept = [tex]\frac{-13}{6}[/tex]
y - intercept = - 13

C: 2/9
D: 1/9
Answer:
d
Step-by-step explanation:
when fractions have the same whole which here is 9 you can just look at the first letters
so one is the smallest
Answer:
1/9 or D
Step-by-step explanation:
8/9 = About 0.89 = 89%
5/9 = About 0.56 = 56%
2/9 = About 0.22 = 22%
1/9 = About 0.11 = 11%
The reason it is D is that it has a low fraction, decimal number, and percent.

Area of triangle- please help :)
Answer:
[tex]\approx 45.1\:\mathrm{w/\: some \: MOE}[/tex]
Step-by-step explanation:
The area of [tex]ABCD[/tex] is comprised of two triangles, so we can find the area of both triangles and add them to get the total area of
Since the sum of the interior angles of a triangle add up to [tex]180^{\circ}[/tex], we have:
[tex]\angle C=180-44-38=\fbox{$98^{\circ}$}[/tex].
The Law of Sines is given as:
[tex]\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}[/tex] for any triangle.
Therefore, we have the proportion:
[tex]\frac{\sin 98^{\circ}}{10}=\frac{\sin 44^{\circ}}{BC},\\BC=\frac{10\cdot \sin 44^{\circ}}{\sin 98^{\circ}},\\BC\approx 7.01[/tex].
Now that we have two sides of a triangle and the angle between them, we can use [tex][\triangle]=\frac{1}{2}ab\sin C[/tex] to find the area of [tex]\triangle CBD[/tex]:
[tex][CBD]=\frac{1}{2}\cdot 10\cdot 7.01 \cdot \sin 38^{\circ},\\\\\left [CBD]\right\approx 21.58[/tex].
Since [tex]\triangle ABD[/tex] is a right triangle, we can use basic trig rules for a right triangle to solve for the sides:
[tex]\sin 55^{\circ}=\frac{AB}{10},\\AB=10\sin 55^{\circ},\\AB\approx 8.19[/tex],
[tex]\sin 35^{\circ}=\frac{AD}{10},\\AD=10\sin 35^{\circ},\\AD\approx 5.74[/tex].
Therefore, the area of [tex]\triangle ABD[/tex] is:
[tex]\frac{1}{2}\cdot 8.19\cdot 5.74\approx 23.49[/tex].
The area of [tex]ABCD[/tex] is then
[tex]21.58+23.49=45.07=\fbox{$45.1$}[/tex].
[tex]\bigstar[/tex] Note that intermediate results were rounded during this calculation. Therefore, there is a small margin of error when rounding to final answer to one decimal place. I recommend plugging in values for yourself using all equations I wrote above, then rounding only your final answer to one decimal place as requested by the problem.
