What does the leading term of −5x^4+4x^3−6x^2+8 tell you?
Step-by-step explanation:
The leading term is -5x^4, which tells us the highest degree of the polynomial.
The leading term in the equation tells us about the degree and whether the curve opens outwards on inwards
What is an equation in one variable?
An equation is a polynomial in one variable with a finite degree
We are given an equation
[tex]-5x^4+4x^3-6x^2+8[/tex]
In this the leading term is -5x^4
Here the coefficient is negative this tells us that the curve opens downwards. if the coefficient has been positive then the curve would open outwards.
Also from the leading term we can find out the degree of the highest variable. the degree of highest variable in this case is 4
Hence, The leading term in the equation tells us about the degree of the variable and whether the curve opens outwards on inwards

Answer:
See below
Step-by-step explanation:
1. Multiply m to get, m(s + z)/2 => (ms + mz)/2
2. Mutiply by 2 by both sides
2B = MS + MZ
3. Divide By M
2B = M(S+Z)
2B/M = S+Z

Given:
Angle A = 120 degrees
Side opposite angle C = 150 meters
Side opposite angle B = 275 meters
Find:
Angle B
Solution:
Since we have two sides given and an included angle, we can use cosine law.
Let's look for the length of the side opposite Angle A first.
[tex]a^2=b^2+c^2-2bc\cos A[/tex]where a = length of the side opposite Angle A or side BC
b = side opposite Angle B or Side AC
c = side opposite Angle C or Side AB
A = Angle A
Since we already have the data above, let's plug it in to the formula we have.
[tex]a^2=275^2+150^2-2(275)(150)\cos 120[/tex]Then, solve a.
[tex]\begin{gathered} a^2=75,625+22,500-82,500(-0.5) \\ a^2=98,125+41,250 \\ a^2=139,375 \\ \sqrt[]{a^2}=\sqrt[]{139,375} \\ a\approx373.3296\approx373.33 \end{gathered}[/tex]Hence, the length of side opposite a or Side BC is approximately 373.33 meters.
Now, to solve for Angle B, we can use the sine law.
[tex]\frac{\sin A}{a}=\frac{\sin B}{b}[/tex]Let's plug in the value of Angle A, side BC or a, and side AC or b to the formula.
[tex]\frac{\sin120}{373.3296}=\frac{\sin B}{275}[/tex]Then, solve for Angle B.
[tex]\begin{gathered} \sin B=\frac{275\sin 120}{373.3296} \\ \sin B=0.6379268552 \\ B=\sin ^{-1}0.6379268552 \\ B\approx39.64 \end{gathered}[/tex]Therefore, the bearing of ship C from ship B is approximately 40 degrees. (rounded off to the nearest degree)

Let x be the number of children and let y be the number of adults.
We know that the total number of attendants was 147, then:
[tex]x+y=147[/tex]We also know that each child ticket cost $4 and for each adult cost $12, and the total amount collected were $1156. Then we have:
[tex]4x+12y=1156[/tex]Hence we have the system:
[tex]\begin{gathered} x+y=147 \\ 4x+12y=1156 \end{gathered}[/tex]Now we have to solve the system. To do that we solve the first equation for y:
[tex]y=147-x[/tex]and we plug this value into the second equation and solve for x:
[tex]\begin{gathered} 4x+12(147-x)=1156 \\ 4x+1764-12x=1156 \\ -8x=1156-1764 \\ -8x=-608 \\ x=\frac{-608}{-8} \\ x=76 \end{gathered}[/tex]Now that we have the value we can find the value of y, then:
[tex]\begin{gathered} y=147-76 \\ y=71 \end{gathered}[/tex]Therefore there were 76 children and 71 adults.

hello i have a upcoming test and want to know how to solve this
Expression given:
[tex]g>1[/tex]To know how to graph the given expression, it is easier if we determine what it means in words. In this case, this expression means all the values above one (without including one).
We know that one is not included as it has the sing ">", if the value were included, then it would have the sing "≥" or "≤".
This is important because when you are graphing, a discontinuous line is drawn for values not included, and a continuous one for included values.
Now, we would have to evaluate if it is the independent variable (generally called x), or the dependent variable (generally called y).
Assuming that g is the dependent variable, then the graph would be like this:
However, if the variable was de independent variable, then it would look like this:
We have to note that both graphs go from 1 to bigger values.
4. Which number produces anirrational answer when multipliedby 0.79?A.B. 0.383838...C. 0.12D.קשותU
Recall that the product between two rational numbers is always a rational number, and the product between an irrational number and a rational number different from zero is always an irrational number.
Also, recall that a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p, and a non-zero denominator q.
Now, notice that:
[tex]\begin{gathered} 0.79=\frac{79}{100}, \\ 0.383838\ldots=\frac{38}{99}, \\ 0.12=\frac{12}{100}. \end{gathered}[/tex]Therefore, 0.79, 0.383838..., 0.12 are rational numbers.
Now, recall that:
[tex]\sqrt[]{7}[/tex]is an irrational number.
Therefore, the product between 0.79 and √7 is an irrational number.

The following congruence statements a, b, e, f are correct.
Triangle congruence: If all three corresponding sides and all three corresponding angles seem to be equal in size, two triangles are said to be congruent.
When two triangles are congruent, their sides and corresponding angles are identical.
Therefore, if GHI is congruent to LMN, then GH =LM, HI=MN and GI=LN, and also angle G=angle L, Angle H=angle M, while angle I = angle N, therefore the correct answers is f) ∠M= ∠H, (a) GH = LM b) ∠L=∠G. and e)IH=NM.

For the function f(x), = 10 (√x + 9), find f-¹(x).
The inverse of the function f(x) = 10 (√x + 9) is f⁻¹(x) = (x - 90)² / 100
Given,
The function, f(x) = 10 (√x + 9)
We have to find the inverse of the function, f⁻¹(x)
Here,
f(x) = 10 (√x + 9)
f(x) = 10√x + 90
Replace f(x) with y.
y = 10√x + 90
Swap x with y;
x = 10√y + 90
Solve for y
That is,
x = 10√y + 90
x - 90 = 10√y
(x - 90) / 10 = √y
Square both sides
((x - 90) / 10)² = √y²
(x - 90)² / 100 = y
Replace y with f⁻¹(x)
That is,
f⁻¹(x) = (x - 90)² / 100
Therefore,
The inverse for the function f(x) = 10 (√x + 9) is f⁻¹(x) = (x - 90)² / 100

For how many games would the cost be the same? Write and solve an equation to determine the number of games for which the cost would be the same.
NEED FAST RESPONSE EQUATION AND SOLUTION
The equation is 6.75x = 5.875y
The price will be the same for 47 Go Golf games and 54 Golf Games
Go Golf charges for the ball and club rental = $2.50
Go Golf charges per game = $4.25
Total charges for Go Golf for one game = $6.75
Golf Games charges for the ball and club rental = $3.25
Golf Games charges for two games = $8.50
Total charges for Golf Game for two games = $11.75
Per game charges = $11.75/2 = $5.875
Let x be the number of games for Go Golf and y be the number of games for Golf Games
Formulating the equation we get:
6.75x = 5.875y

An investment firm invested in two companies last year. They invested $12,000 in Company A and made a profit of 14%. They
invested $8000 in Company B and made a profit of 21%.
Answer the questions below. Do not do any rounding.
(a) What was the investment firm's total profit?
$0
(b) What was the percent profit for their total investment?
The investment firm's total profit is $ 3360 and the percent profit for their total investment is 16.8%.
How to calculate percentage of a situation?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it. There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of anything, we mean that it is 50% of everything.
Formula for percentages: (Value/Total value) * 100
Given, amount invested in company A = $ 12,000
Amount invested in company B = $ 8000
Profit earned by company A = 14%
Profit earned by company B = 21%
Amount in profit earned from company A = (12000*14)/100 = $ 1680
Amount in profit earned from company B = (8000*21)/100 = $ 1680
Therefore total profit of the investment firm = $ (1680 + 1680) = $ 3360
Thus, the investment firm's total profit is $ 3360.
Now, percentage profit of total investment = (3360/20000)*100 = 16.8%, using available literature and formula.
Thus, the percent profit for their total investment is 16.8%
