A formula for 6 gallons of light green paint uses 3/8 gallon of white paint. Liam has 9/16 gallon of white paint. Does Liam have enough white paint to make 8 gallons of light green paint? If not, how much more does he need?

Answer:

0.25x+1.75

Step-by-step explanation:

A linear equation is of the form ax+b. Set a up a system of equation with -3 and 13 substituted in to ax+b. We get -3a+b=1 and 13a+b=5. Solving tis gives us a,b=(0.25,1.75)

Answer:

f(x) = [tex]\frac{1}{4}[/tex] x + [tex]\frac{7}{4}[/tex]

Step-by-step explanation:

a linear function has the form

f(x) = ax + b ( a and b have to be found )

given f(- 3) = 1 and f(13) = 5 , then by substitution

- 3a + b = 1 → (1)

13a + b = 5 → (2)

subtract (2) from (1) term by term to eliminate b

- 3a - 13a = 1 - 5

- 16a = - 4 ( divide both sides by - 16 )

a = [tex]\frac{-4}{-16}[/tex] = [tex]\frac{1}{4}[/tex]

substitute a = [tex]\frac{1}{4}[/tex] into (1) and solve for b

- 3( [tex]\frac{1}{4}[/tex] ) + b = 1

- [tex]\frac{3}{4}[/tex] + b = 1 ( add [tex]\frac{3}{4}[/tex] to both sides )

b = 1 [tex]\frac{3}{4}[/tex] = [tex]\frac{7}{4}[/tex]

f(x) = [tex]\frac{1}{4}[/tex] x + [tex]\frac{7}{4}[/tex] ← is the linear function

or

f(x) = 0.25x + 1.75

Answer:

Step-by-step explanation:

[tex]a^{2} + b^{2} = c^{2} \\4^{2} +b^{2} = (\sqrt{52} )^{2} \\16 + b^{2} = 52\\b^{2} =36\\\sqrt{b^2} =\sqrt{36} \\b=6\\[/tex]

One of the possible x-values of point F will be 6 units to the right of point G. So, the x-value of point F could be 7, since 1+6=7. That means one possible location of point F is (7,8).

The other possible x-value of point F will be 6 units to the left of point G. So, the x-value of point F could be -5, since 1–6=–5. That means the other possible location of point F is (–5,8).

So the answer is:

(7,8) and (-5,8)

The percentage of the increase in population is 4%

From the question, we have the following parameters that can be used in our computation:

Initial population = 209000

New population = 2017360

The percentage of the increase is then calculated using the following percentage equation

Percentage increase = (New population  - Initial population )/Initial population  * 100%

Substitute the known values in the above equation, so, we have the following representation

Percentage increase = (217360 - 209000)/209000 * 100%

Evaluate

Percentage increase = 4%

Hence, the increase percentage is 4%

Answer:

Step-by-step explanation:

We can solve this using PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). We do parentheses first, then exponents, all the way down to subtraction:

1. Parentheses

(1 + 3)³ -(2)2 + 4

4³ - (2)2 + 4

(By the way, (2)2 is considered multiplication not parentheses).

2. Exponents

4³ - (2)2 + 4

64 - (2)2 + 4

3. Multiplication

64 - (2)2 + 4

64 - 4 + 4

4. Division

None.

5. Subtraction

(Even though PEMDAS is labeled as addition before subtraction, in the MD | AS part, whichever one comes first in either section of the equation goes first):

64 - 4 + 4

60 + 4

Order of operations/PEMDAS:

Division, Addition, Subtraction

Here is why:

using the order of operations,

do 4/-2 First

4/-2 = -2

Then do -7 + (-2)

-7 + (-2) = -2

When adding a negative plus a negative, it stays negative,

so the expression -7 +(-2) is like 7+2, it will equal 9, but because it is a negative plus a negative, the answer is negative.

As below it is described what is exponential function with some examples.

A function is simply a “mapping” between 2 sets of objects (usually numbers but they could really be anything) such that, every object in the first set (the domain) is mapped to a single object in the second set. What you usually see as examples of functions (e.g. f(x)=x²) actually define the relationship between the sets. This is what I mean by “mapping”. Often, we don’t explicitly state what the sets are, because it’s understood from the context, but technically, it’s not a function unless we state the sets. E.g., instead of saying f(x)=x², we should say f:x↦x²|x∈ℂ (pronounced “f maps x to x² such that x is a complex number”), meaning that we map the complex numbers to themselves using the rule that we square each input. You can define it differently, so that, for example, we map complex to reals. However, and this is important, that would be a different function, even though the “rule” for turning inputs into outputs is the same.

Exponential Function:

Exponential functions are functions of the form f(x) = b^x where b is a constant.

The real mathematical importance of exponential functions is in their being proportional to their derivatives meaning the bigger x is, the steeper the slope of the function. This means they grow extremely fast: exponentially fast.

A common example of exponential growth is a bacterial population. Since bacteria reproduce rapidly by mitosis, for every bacterium in a culture, there will, before long be two bacteria. Thus, if I have 10 bacteria to start, one minute later I will have 20, and in another minute, each of those twenty will have reproduced and I will have 40; one minute later the same will have happened again and before long, the culture will be overrun with bacteria. The more bacteria there are, the more bacteria there are to make even more bacteria the next minute.

All exponential functions are proportional to their derivatives, but the function f(x) = e^x (where e = 2.718281828459…) is actually equal to its derivative meaning the y value of the function at a particular x value is equal to the slope of the curve at that same x value. Thus when dealing with exponential functions in calculus, e becomes a very natural number to use as a base. This is why e is such a big deal and why teachers try to introduce the number early on in Algebra 2, even though it doesn’t have much use at that point in one’s mathematical education.

When plotting an exponential curve by hand, one ought to simply pick whole number x values and multiply the base by itself an x number of times to calculate the corresponding y value. This will give a rough plot of the graph of the curve, although a calculator is requires to plot the points not on whole number x values. The curve of simple exponential functions is always increasing and concave up, or vice versa for b^-x. For a positive exponential function like f(x) = e^x, as x approaches ∞, f(x) approaches ∞, and as x approaches -∞, f(x) approaches 0. The curve has no absolute maximum or minimum value and has a horizontal asymptote at y = 0.

For the given quadratic equation we have:

a) F(-2) = 5

b) F(3) = 40

c) the solutions are:

t = -1

t = -1/3

Here we have the following quadratic function:

F(t) = 3t^2 + 4t + 1

a) First, we want to determine the value of F(-2), to do so, we just need to replace the values of the variable, t, by the number -2, we will get:

F(-2) =3*(-2)^2 + 4*(-2) + 1

F(-2) = 3*4 - 8 + 1 = 5

F(-2) = 5

b) Now we want to find the value of the F(3), so this time we evaluate in x = 3.

F(3) =3*3^2 + 4*3 + 1

F(3) = 27 + 12 + 1 = 40

F(3) = 40

c) Last, we want to solve:

F(t) = 0

So we need to solve the quadratic equation:

3t^2 + 4t + 1 = 0

Using the quadratic formula we will get the two solutions:

[tex]t = \frac{-4 \pm \sqrt{4^2 - 4*3*1} }{2*3} \\\\t = \frac{-4 \pm 2}{6}[/tex]

Then the two solutions are:

t = (-4 + 2)/6 = -2/6 = -1/3

t = (-4 - 2)/6 = -1

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are present. The variables in the above equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

a) The independent variable in this problem is the number of days, represented as x. The amount of money left, the y variable is the dependent variable since it depends on the number of days left (x).

b) If there are 10 days left, we can plug it into the given equation to find the balance in the account.

Since Anthony is 30, the largest amount he can contribute and deduct from his Form W-2 for the traditional IRA for 2021 is $6,000.

The traditional IRA or individual retirement account is a pre-tax contribution an employee saves towards retirement.

With a traditional IRA, Anthony can contribute pre- or after-tax dollars, allowing his savings to grow tax-deferred while withdrawals are taxed as current income unless after the age of 59½.

An additional tax of 10% may apply if Anthony withdraws from his traditional IRA before reaching 59½ years.

However, one advantage of the traditional IRA is that the employee invests more funds upfront since the deduction is mostly made before tax.
