Step-by-step explanation:
The given possible roots have the form that we'd get by using the quadratic formula, so let's start with that. Here the coefficients are {2, -6, 3}, and so the discriminant (b^2 - 4ac) is (-6)^2 - 4(2)(3), or 36 - 24 = 12.
Because the discriminant is positive we know immediately that there are two different real roots.
-(-6) ± √12 6 ± √12

Frank weighs 160 pounds and is on a diet to gain 2 pounds a week so that he can make the football team. John weighs 208 pounds and is on a diet to lose 3 pounds a week so that he can be on the wrestling team in a lower weight class. If Frank and John can meet these goals with their diets, when will they weigh the same, and how much will they weigh at that time? (Hint: Solve for x and y and make sure you write a complete sentence for an answer)
Answers
Answer: If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.
Step-by-step explanation:
Let x = Number of weeks.
As per given question ,
Weight of Frank after x weeks = 160+2x (pounds)
Weight of John after x weeks = 208-3x (pounds)
When Weight of Frank= Weight of John
Weight of Frank after 9.6 weeks = 160+2(9.6) = 179.2 pounds
Weight of John after 9.6 weeks = 208-3(9.6)=179.2 pounds
Hence, If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.
find the unknown angle mesure
Answers
Answer: 1=65° and 5=43
Step-by-step explanation:
Question 1:
Angles on a straight line always add up to 180°.
So to find the angle of x on the first question you have to do 180-115=65°
You would have to use this method for questions 2, 3 and 4 as well.
Question 5:
Right angles always add up to 90° so to work out what x is you would have to do 90-47=43
You would have to use this method for questions 6, 7 and 8.

Answer:
x = $11
Step-by-step explanation:
5x = $55
9x = $99
2x = $22
In order to find the relationship between x and y, all we have to do is divide y by the term.
$55 ÷ 5 = 11
$99 ÷ 9 = 11
$22 ÷ 2 = 11
Therefore, each ticket sold is $11, or x = $11
Independent = cups of milk poured Dependent = Milk left in the gallon jug Independent = Milk left in the gallon jug Dependent = cups of milk poured
Answers
Answer:
Independent = Milk left in the gallon jug
Dependent = cups of milk poured
Step-by-step explanation:
In an experiment or a research, a variable is defined as the thing or a phenomenon that you are trying to found out or measure. Variables can be independent variable as well as the dependent variable.
Independent variable is the variable that the researcher or the experimenter can change or manipulate in the research. This variable does not depend on others and thus stands alone. Its value can be change or altered to find the changes in the dependent variables. They are used as treatment variables.
Whereas, the dependent variables are those variables that are dependent on the values of the independent variables. It is considered as the effect of the independent variable. An independent variable is often manipulated to measure the outcome in the dependent variable.
In the context, the cups of milk poured is the dependent variable and the independent variable is the amount of milk left in the jug.

11259.5
Step-by-step explanation:
25×386+3219÷2
Multiply 25 and 386 to get 9650.
9650+3219/2
Convert 9650 to fraction 19300/2.
19300/2+3219/2
Since 19300/2 and 3219/2 have the same denominator, add them by adding their numerators.
19300+3219/2
Add 19300 and 3219 to get 22519.
22519/2
Divide 22519 by 2 to get 11259.5.

Jim and bill each invest $15,000 into savings accounts that earn 3.5% interest. Jims account earns simple interests and bills account earns compound interest. After 25 years, who will earn more interest and how much more will he earn.
Answers
Answer:
Bill will earn more interest
He will earn $ 20,448.67 from his investment
Step-by-step explanation:
Firstly let us calculate Jim's earnings based on simple interest
A = P(1 + rt)
Calculation:
First, converting R percent to r
a decimal
r = R/100 = 3.5%/100 = 0.035 per year.
Solving our equation:
A = 15000(1 + (0.035 × 25)) = 28125
A = $28,125.00
The total amount accrued, principal plus interest, from simple interest on a principal of $15,000.00 at a rate of 3.5% per year for 25 years is $28,125.00 for Jim
Now let's us calculate bill's investment based on compound interest
Equation
A = P(1 + r)^t
A=15000(1+0.035)^25
A=15000(1.035)^25
A=15000*2.36324498427
A = $ 35,448.67
We see that Bill will earn
$ 20,448.67 from his investment

Apply distributive property
[tex](a)\ 2a + 7a[/tex]
Apply distributive property [Factor out a]
[tex]2a + 7a = a(2 + 7)[/tex]
[tex]2a + 7a = a(9)[/tex]
Open bracket
[tex]2a + 7a = a*9[/tex]

[tex]5z - 10 = 5(z - 2)[/tex]
[tex](c)\ c - c^2[/tex]
Express c as c * c
[tex]c - c^2 = c - c * c[/tex]
Apply distributive property [Factor out c]
[tex]c - c^2 = c(1 - c)[/tex]
[tex](d)\ r + r+ r+ r[/tex]
Express r as r * 1
[tex]r + r + r + r = r * 1 + r * 1 + r * 1 + r *1[/tex]
Apply distributive property [Factor out 1]
[tex]r + r + r + r = r(1+1+1+1)[/tex]
[tex]r + r + r + r = r * 4[/tex]
[tex]r + r + r + r = 4r[/tex]
[tex](e)\ 2x - \frac{1}{2}[/tex]
Express 2x as 4x/2
[tex]2x - \frac{1}{2} = \frac{4x}{2} - \frac{1}{2}[/tex]

Answer:
$45,395.39
Step-by-step explanation:
The formula for an amount earning compound interest is ...
A = P(1 +r/n)^(nt)
where principal P is invested at annual rate r compounded n times per year for t years.
Using the given numbers, we have ...
A = $10,000(1 +0.038/4)^(4·40) ≈ $45,395.39
The charity will receive $45,395.39.
How would you limit the domain to
make this function one to one?
f(x) = (x + 3)^2
Answers
Answer:
Domain would be x ≥ -3.
So enter -3.
Step-by-step explanation:
This is a parabola with line of symmetry x = -3.
When x has values like say -4 and -2, f(x) will have a value of 1 making the function many to one.
So, to make it one to one, x would have to be equal or greater than -3.
A function assigns values. The limit of the domain to make this function one to one is x≥3.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
A one to one function is a function whose every input gives a distinct output. Now given the function is a quadratic function, therefore, the function will have the same output for multiple inputs.
Since the symmetrical axis for this function lies at x=-3, therefore, for the function to be one to one the domain of the function must be greater than or equal to 6.
Hence, the limit of the domain to make this function one to one is x≥3.

2. Subtract 24 from both sides.
6x+24=0
6x+24-24=0-24
3. Simplify
6x=-24
4. Divide both sides of the equation by the same term
6x=-24
[tex]\frac{6x}{6}[/tex] = [tex]\frac{-24}{6}[/tex]

Answers
Answer:
41.29 cm²
Step-by-step explanation:
From the question,
Area of the shaded portion = Area of the circle - area of the square.
A' = πr²-L²...… Equation 1
Where A' = Area of the shade portion, r = radius of the circle, L = length of the square, π = pie
Given: r = 4 cm, L = 3 cm
Constant: π = 22/7.
Substitute these values into equation 1
A' = [(22/7)×4²]-3²
A' = 50.29-9
A' = 41.29 cm²
Hence the area of the shaded portion is 41.29 cm²
