Not sure!!An unknown polynomial is added to the expression -3x^3+2x-5 and the resulting sum is 4x^3+7x^2-3. what is the unknown polynomial?
Answer:
7x³ + 7x² + 2x - 8
Step-by-step explanation:
Let the unknown polynomial be a
a + -3x³ + 2x - 5 = 4x³ + 7x² - 3
a = 4x³ + 7x² - 3 - (-3x³ + 2x - 5)
a = 4x³ + 7x² - 3 + 3x³ + 2x - 5
a = 7x³ + 7x² + 2x - 8
Convert 32 kilometers per hour to miles per day. (3.28 feet 1 meter)
Answer:
477.09 mi/da
Step-by-step explanation:
If student must use conversion given, 3.28ft = 1m, then the following works:
32km/hr = ______mi/da 1 day = 24 hrs, 1m=3.28ft, 1km=1000m,1mi=5280ft
32km/hr x 24hr/day x 1000m/1km x 3.28ft/1m x 1mi/5280ft = 477.09mi/da
If student can use 1km = 0.62mi, some steps can be skipped.

Write the equation of the line that passes through the points(-3,6) and (4,1). In point slope form
Answer:
y=10x-14
Step-by-step explanation:
From (4,1) on a graph, you would rise ten and then run to the left 14 times. Remember the rise/run and follow it. What I'm telling is rise you reach (4,6), then count across to (-3,6) to get your answer. You can use demos graphing calculator to help you better or make your own graph.

The following set of points are on the graph of a function:
x y
2 5
3 6
4 7
5 8
6 9
7 10
Which point would be on the inverse of this function?
Group of answer choices
(-10, -7)
(-6, -3)
(-2, -5)
(9, 6)
Point (9, 6) would be on the inverse of this function so option (D) will be correct.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
Given the sets of coordinates of a function.
An inverse function is the reciprocal of a function and the coordinate of the inverse function is interchanged with the original function.
For example, if (x,y) is the coordinate of the function then (y,x) will be the coordinate of the inverse of the function.
Since option (D) (9, 6) is the interchange of (6,9) so it will be the inverse of a function.
Hence "Point (9, 6) would be on the inverse of this function".

What is the measure of angle 3?
1
Answer:
129
Step-by-step explanation:
Every angle would be similar to each other with having only TWO different degrees...
Each line ( <----------------------> ) equals 180 (never 360, b/c that would be a circle)
Now with you only having 51 as a degree, you need to do 180-51 which gives you 129, with that given, this tells you number 1 and 3 is both 129, and angle 2 is 51.

i dont know
Step-by-step explanation:
The speed of light in a vacuum is 2.998×108 m/s .
What is its speed in miles per minute (mi/min)?
To convert m/s to mi/min we have to find conversion factor first
1 mile = 1609.344 m
1m = 1/1609.344 miles
1 min = 60 s
1s = 1/60 min
Let’s put mi/min instead of m/s according to equations above
m/s = [1/1609.344 miles] / [1/60 min]
The conversion factor is
f = 60 / 1609.344
Now we can convert m/s to mi/min
V (mi/min) = 2.998 ∙ 108 m/s ∙ f = 2.998 ∙ 108 ∙ (60 / 1609.344) = 1.118 ∙ 107 mi/min
Answer: V = 1.118 ∙ 107 mi/min
Hope u have a good day of learning
1 mile = 1609.344 m
1m = 1/1609.344 miles
1 min = 60 s
1s = 1/60 min
Let's put mi/min instead of m/s according to equations above
m/s = [1/1609.344 miles] / [1/60 min]
The conversion factor is
f = 60 / 1609.344
Now we can convert m/s to mi/min
V (mi/min) = 2.998-108 m/s f= 2.998 108 (60/1609.344) = 1.118-107 mi/min
Answer: V = 1.118 - 107 mi/min

4x - 3=2x+7
4x - 3-0=2x + 7-O
Ox - 3=0
Answer:
0
Step-by-step explanation:
The graphs of f(x) and g(x) are shown below.
On a coordinate plane, a straight line with a positive slope represents f (x) = x minus 3. The line goes through (0, negative 3) and (3, 0). On a coordinate plane, a straight line with a negative slope represents g (x) = negative 0.5 x. The line goes through (negative 4, 2), (0, 0), and (4, negative 2)
For what interval is the value of (f – g)(x) negative?
9514 1404 393
Answer:
x < 2 or (-∞, 2)
Step-by-step explanation:
(f -g)(x) = (x -3) -(-0.5x) = 1.5x -3
We want to find (f -g)(x) < 0, so we have ...
1.5x -3 < 0
1.5x < 3 . . . . . . . add 3
x < 2 . . . . . . . . . .divide by 1.5
The function (f -g)(x) is negative on the interval x < 2.
The choices are
A. 6
B.9
C.4 1/6
D.8 1/3
Answer:
D. 8 1/3

solve each traingle
the bottom one:
the line that cut the traingle, made each angle is 90°
10/sin90° = 5/sin?
sin? = 5sin90°/10 = 1/2
the angle is sin^-1 (1/2) = 30° ⇒
10/sin90° = ?/sin60°
? = 10sin60°/sin90° = 5√3 ⇒
12/sin90° = 5√3/sin?
sin? = 5√3 sin90°/12 = 5√3 /12
? ≈46°
180 - (46+90) = 44° ⇒
x/sin44° = 12/sin90°
x = 12sin44°/sin90° = 8.3
x = 8 1/3

What factors of -27 have the sum of 6
Answer:
9 and -3
Step-by-step explanation:
9 and -3 are both factors of -27 since they can be multiply each other to get -27. Also, they both add up to 6.
The factors of -27 that sum up to 6 are 9 and -3
How to determine the factors of -27 that sum up to 6From the question, we have the following parameters that can be used in our computation:
Factors = -27
Sum = 6
Let the numbers be x and y
So, we have
xy = -27
x + y = 6
Let x be 9 and y be 3
So, we have
9 * -3 = -27
9 - 3 = 6
Hence, the numbers are 9 and -3
