write each polynomial in standard form. Then give the leading coefficient. You may need to combine like terms before writing the polynomial in standard form.
10-3x²+x^5 + 4x³
Answers
Step-by-step explanation:
To write a polynomial in standard form, put the degree that are the greatest first
So here it would be
[tex] {x}^{5} + 4 {x}^{3} - 3 {x}^{2} + 10[/tex]
Remember constant are numbers that you learned back in elementary,
Numbers like 10,90,4,1,0,-3 etc.
Remember that constant are basically represented like this
[tex]k \times {x}^{0} [/tex]
For example, 10 is represented like
[tex]10 \times {x}^{0} [/tex]
Since 0 is the smallest degree possible, for a polynomial, constants are the last term of a polynomial in standard form

======================================================
Explanation:
Let's solve the first inequality for x.
4x-5 ≥ 3
4x ≥ 3+5
4x ≥ 8
x ≥ 8/4
x ≥ 2
Now solve the other inequality
5 - x > 8
5 > 8+x
8+x < 5
x < 5-8
x < -3
The two solutions we get are x < -3 or x ≥ 2
These two regions do not overlap. The key word "or" connecting the original inequalities also applies to the solutions.
Either x is smaller than -3, OR it is 2 or larger
I recommend drawing out a number line and shading the appropriate regions. The two disjoint regions do not connect which means we have a union of the two regions.

Answers
Answer:

Step-by-step explanation:
3 lots of 'n' and 5 means 3 times both values so these values are put into a bracket with a common multiplier (ie. the 3)
3(5 - n)
16 more than 2 lots of 'n' means that n has to be doubled. n + n = 2n. add 16 to this and we have
2n + 16
if these values are both equal (hence why they are in an equation) then all that is needed is for them to be set equal alongside each other.

It is also the point on the curve in which the curve starts rising or falling.
Analysis:
[tex]27(x-64)^{2}[/tex] + 43
27(x-64)(x-64) + 43

The perimeter of a triangle is 44cm. One side is 4cm shorter than the second side and twice as long as the third side. Find the length of each side of the triangle.
Answers
The 1st, 2nd, and 3rd sides of the triangle are 16, 20, and 8 respectively.
Given that the perimeter of the triangle is 44 cm.
Let us consider a side 's' which is 4 cm shorter than the second side.
That means the second side is 4 cm longer than s, hence the second side is s+4 cm in length.
We also have that the side of length s is of length twice as long as the third side.
Hence, the length of the third side is half that of s so, it is of length s/2.
Hence, at the end 44=s+(s+4)+(s/2)=s(2+1/2)+4
⇒ s(5/2)=40
⇒ s=8*2=16
So, the 1st, 2nd, and 3rd sides of the triangle are 16, 20, and 8 respectively.

to get CD we use again Pythagoras. there is a smaller right-angled triangle on top of the BCD rectangle.
so, AD = 11 = 4 + 7
7 = the vertical leg of the upper right-angled triangle.
the horizontal leg is congruent to CD and is

d)After how many seconds (round to nearest 100th) does the bullet hit the ground?
please help asap!
Answers
Answer:
a) 50 meters
b) 2354 meters
c) 12 seconds
d) 24.13 seconds
Step-by-step explanation:
Hello!
a) How far is Lincoln above the ground when he shoots the gun?We need to really understand what the variables represent in this question. Given that t is time, and h is height, the time at which he shoots the bullet will be 0, as the bullet hasn't started traveling yet. This means that we can solve for the original height of the bullet by plugging in 0 for time in the equation.
Equation: [tex]h = -16t^2 + 384t + 50[/tex]
Plug in 0 for t:
[tex]h = -16t^2 + 384t + 50[/tex][tex]h = -16(0)^2 + 384(0) + 50[/tex][tex]h = 50[/tex]The height at which Lincoln shot the bullet is 50 meters.
We can also look at this graphically. The height of origin will simply be when the x-value (in this case t-value) is 0. That means it is the point at which the graph intersects the y-axis, known as the y-intercept.
Standard form of a Parabola: [tex]y = ax^2 + bx + c[/tex]
The y-intercept is the "c" value.
Given our equation: [tex]h = -16t^2 + 384t + 50[/tex]
The c-value is 50. This proves that the y-intercept is 50.
b)How high does the bullet travel vertically relative to the ground?We want to find the highest point of the graph. To do that, we can find the vertex.
We can utilize the Axis of Symmetry (AOS) to find the Vertex.
First, find the AOS using the formula: [tex]AOS = -\frac{b}{2a}[/tex]
a = -16b = 384Plug it into the formula:
[tex]AOS = -\frac{b}{2a}[/tex][tex]AOS = -\frac{384}{2(-16)}[/tex][tex]AOS = \frac{384}{32}[/tex][tex]AOS = 12[/tex]Plug in 12 for t in the equation:
[tex]h = -16t^2 + 384t + 50[/tex][tex]h = -16(12)^2 + 384(12) + 50[/tex][tex]h = -2304 + 4608 + 50[/tex][tex]h = 2304+50[/tex][tex]h = 2354[/tex]Therefore, the highest point of the bullet is 2354 meters.
c)How long does it take the bullet to reach its greatest height?We answered this in the last question. The t-value when h is at its highest is 12.
d)After how many seconds (round to nearest 100th) does the bullet hit the ground?We have to solve for the values of t when h is 0 (when it touches the ground).
Set the equation to 0, and solve using the quadratic formula.
Quadratic formula: [tex]x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}[/tex][tex]x = \frac{-384\pm\sqrt{384^2 - 4(-16)(50)}}{2(-16)}[/tex][tex]x = \frac{-384\pm\sqrt{147456 +3200}}{-32}[/tex][tex]x = \frac{-384\pm\sqrt{150656}}{-32}[/tex][tex]x = \frac{-384\pm388.14}{-32}[/tex][tex]x = -\frac{4.14}{32}, x = \frac{772.14}{32}[/tex]We are only going to take the positive solution, as we can't have a negative time. The solution that doesn't work is called an extraneous solution.
[tex]x = \frac{772.14}{32}[/tex][tex]x = 24.13[/tex]It takes approximately 24.13 seconds for the bullet to hit the ground.

Given Information :
The ratio of heights of the two girls = 5:7
Assumption
Consider their height be 5X cm and 7X cm
The height of the first girl = 5X cm
But According to the condition mentioned in given problem
The height of the first girl = 192 cm
=> 5X = 192
=> X = 192/5
=> X = 38.4
Therefore, X = 38.4 cm
Now the height of the second girl = 7X cm
=> 7 × 38.4 cm
=> 268.8 cm
♦ Alternative Method♦ :-
The ratio of the heights of the two girls = 5:7
The height of the first girl = 192 cm
Assume that the height of the second girl = X cm
Therefore, 5:7= 192:X
=> 5/7 = 192/X
=> 5X = 7×192
=> X = (7×192)/5
=> X = 7× 38.4
=> x = 268.8 cm
♦ Answer ♦ :-
The height of the second girl is 268.7 cm
