Brielle made a color using 2 cups of white paint and 3
cups of green paint.
How many cups of green paint should you mix with 4
cups of white paint to make the same color?

Answer:

a) The perimeter of a rectangle is written as:

P = 2*L + 2*W

where L is the length amd W is the width (broad in this case).

here we have:

L = 8cm and W = b

then the perimeter is:

P = 2*8cm + 2*b

And we know that:

18cm ≤ P ≤ 50cm

where ≤ is used because there is written "not more" and "not less", so the equalities are allowed

now we can replace P by the above equation:

18cm ≤ 16cm + 2*b ≤ 50cm

now we can subtract 16cm in each side and get:

18cm - 16cm ≤ 2*b ≤ 50cm - 16cm

2cm ≤ 2*b ≤ 34cm

Now we can divide each side by 2.

1cm ≤ b ≤ 34cm/2 = 17cm

1cm ≤ b ≤ 17cm.

b) Here we have missing information, so this can not be answered.

(only knowing that one side length is x, and another side length is x + 3cm, we can know that x > 0cm, so the minimum value of x is really close to 0cm)

Slope Formula: (y2 - y1) / (x2 - x1)

Line 1: 3

Point 1 = (-5, -8)

Point 2 = (-1, 4)

Slope = (4 - - 8) / (-1 - - 5) = (4 + 8) / (-1 + 5) = 12 / 4 = 3

Line 2: 3

Point 1 = (0, 1)

Point 2 = (2, 7)

Slope = (7 - 1) / (2 - 0) = 6 / 2 = 3

Line 3: -1/3

Point 1 = (6, -7)

Point 2 = (-6, -3)

Slope = (-3 - - 7) / (-6 - 6) = (-3 + 7) / (-12) = 4 / -12 = -1/3

Parallel lines have the same slope, while perpendicular lines have an opposite reciprocal slope.

Line 1 and Line 2 are parallel because they have the same slope.

Line 1 and Line 3 are perpendicular because they have opposite reciprocal slopes.

Line 2 and Line 3 are perpendicular because they have opposite reciprocal slope.

Perpendicular

Step-by-step explanation:

You need to learn this for some tests where you don't get access to the internet in most cases like the ACT, SAT, normal tests, ect.

The formula for slope is y2-y1   divided by x2-x1

y2 is a point from the second pair of points, for example (-1, 4) or (2, 7).

y1 is a point from the first pair like (-5, -8), or (0, 1).

You can plug in the values for example:

4 - (-8)  / -1 - (-5)

Two negatives equals a positive in math, so

12 / 4

= 3.

The slope for line 1 is 3.

You extend this to the other two lines.

For lines to be parallel, they must have the same slope.

1 and 2 should both have a slope of 3 based on the previous algebra, so they are parallel.

Line 3 has a slope of -1/3 which makes it perpendicular to 1 and 2, because perpendicular lines have the negative reciprocals of each other.

For example, if a line has a slope of 2, the perpendicular line has a slope of -1/2 because a reciprocal is the number flipped upside down with a fraction (aka, multiplying something with 1/x where x is the original number.)

A reciprocal slope of 19348 is -1/19348.

Answer:

80 = x

Step-by-step explanation:

The base angles are the same if the side lengths are the same

The unmarked angle is 50 degrees

The sum of the angles is a triangle is 180 degrees

180= 50+50+x

180 = 100 +x

180 -100 = 100+x-100

80 = x

Answer:

80°

Step-by-step explanation:

In an isosceles triangle, if the two sides are the same length, then the two angles formed on the base line are equal.

The other angle on the base line is also equal to 50°.

Angles in a triangle add up to 180°.

x° + 50° + 50° = 180°

x° + 100° = 180°

x° = 180° - 100°

x° = 80°

The zero product property tells us that if the product of two terms is 0, then one of the terms must be equal to 0.

Polynomial functions can be written in intercept form:

\(y=x(x-r)(x-s)(...)\)

In this form, according to the zero product property, r and s are zeros of the function. The first 'x' term also signifies that 0 is also a zero of the function (x = 0).

We're given:

\(y=x(x-2)(x+6)^2\)

In this case, r and s are equal to 2 and -6.

However, there is an x written in the front, indicating that 0 is also a zero of the function.

Answer:

b. would be the answer bc it goes in a line if you were to connect the dots

Under any circumstances, the imaginary number i = √-1. We use i to represent the square root of a negative number because negative numbers cannot have square roots (ex: 2^2 = 4, -2^2 = 4).

So, we have a complex number 2 + i. The absolue value? Simple.

\(|2 + i|\\2 + |\sqrt{-1} |\\2 + \sqrt{1} \\2 + 1\\3\)

If you need an explanation, look at it this way. The number cannot exist. Yet let's assume it did exist for a moment. What would be the absolute value of a negative square root if they could exist? Well, it would be the same as the square root of that number's opposite, it's positive counterpart!

So, what is the positive counterpart of -1? That would be 1. What's the square root of 1? 1! So, why don't we eliminate these steps? Instead of assuming √-1 can exist and then finding the absolute value of that, just skip those steps and instead take √1, or just 1.

So finally: |√-1| = 1

"It is not always helpful to rewrite an equation in standard form as a first step in solving it."

In standard form, the right side of an equation should be 0 and every component on the left side should be 1. For example, x2 = 4; to express this in standard form, move the number 4 to the left side of the equation, resulting in x2 - 4 = 0.

If you are asked to find x in this circumstance, there is no need to write the equation in standard form; simply take this same real number of both of the equation's sides to find x.

Ax+By=C is the common structure for linear equations in two variables. 2x+3y=5, for example, is a simple linear equation. It is rather simple to find both intercepted communications when an equation is stated in this way (x and y). This form is indeed useful for solving two-linear equation systems.

Answer:

two fifths plus four tenth

Step-by-step explanation:

To approximate the change in volume of a spherical balloon as the radius increases from 8m to 8.2m, we can use differentials. The volume of a sphere is given by the formula V = (4/3)πr^3.

Taking differentials of both sides, we have dV = 4πr^2 dr.

At r = 8m, we have dV ≈ 4π(8m)^2 (0.2m) ≈ 160π/3 m^3.

Therefore, the change in volume of the spherical balloon as the radius increases from 8m to 8.2m is approximately 160π/3 m^3.
To approximate the change in volume of a spherical balloon using differentials, we'll use the formula for the volume of a sphere (V) and differentiate it with respect to the radius (r):

V = (4/3)πr³

Now, let's differentiate V with respect to r (dV/dr):

dV/dr = d((4/3)πr³)/dr = (4πr²)

Next, we'll find the differential change in radius (dr) which is the difference between the initial radius and the final radius:

dr = 8.2 m - 8 m = 0.2 m

Now, we can approximate the change in volume (dV) using differentials:

dV ≈ (dV/dr) * dr = (4πr²) * dr

Plug in the given values of r = 8 m and dr = 0.2 m:

dV ≈ (4π(8)²) * (0.2) = (4π(64)) * (0.2) = 51.2π m³

So, the approximate change in volume of the spherical balloon as it swells from a radius of 8 m to 8.2 m is 51.2π m³.

The reason why Verifone Systems would have a valuation allowance almost equal to its deferred tax assets is to avoid the risk of having a significant deferred tax liability.

In 2015, Verifone Systems reported deferred tax assets of $398 million and a valuation allowance of $332 million.

A valuation allowance is an accounting approach that is used to create a contra-asset account on a company's balance sheet. A contra-asset account is a ledger account that offsets the balance of another account. A valuation allowance is used to account for the uncertainty regarding the recoverability of a deferred tax asset.

In essence, a valuation allowance serves as an offsetting contra account to the deferred tax asset that is created when a company has more tax deductions or credits than it has taxable income.

This is why Verifone Systems reported a valuation allowance almost equal to its deferred tax assets.

The rationale behind using a valuation allowance is to ensure that a company does not have a significant deferred tax liability that could affect its financial position. It also ensures that a company's balance sheet accurately reflects the tax consequences of its transactions.

A valuation allowance can also be used to show that a company has reduced its deferred tax assets, which can be beneficial for tax planning and compliance purposes.

If the recipe calls for a ratio of 2 teaspoons of sesame seeds to 1 teaspoon of pepper flakes, then Omar would need approximately 4/3 teaspoons of toasted sesame seeds for 2/3 teaspoon of pepper flakes.

There is no direct conversion factor between teaspoons of toasted sesame seeds and teaspoons of pepper flakes. Therefore, we cannot determine the number of teaspoons of sesame seeds required for 2/3 teaspoon of pepper flakes.

However, if we know the ratio of toasted sesame seeds to pepper flakes required in a recipe, we can use that ratio to determine the amount of sesame seeds required for a given amount of pepper flakes.

For example, if a recipe calls for a ratio of 2 teaspoons of toasted sesame seeds to 1 teaspoon of pepper flakes, then we can use the following proportion to find out how many teaspoons of sesame seeds are needed for 2/3 teaspoon of pepper flakes:

2 teaspoons sesame seeds : 1 teaspoon pepper flakes = x teaspoons sesame seeds : 2/3 teaspoon pepper flakes

Cross-multiplying and solving for x, we get:

x teaspoons sesame seeds = (2 teaspoons sesame seeds / 1 teaspoon pepper flakes) x (2/3 teaspoon pepper flakes)

x teaspoons sesame seeds = 4/3 teaspoons sesame seeds

Therefore, if the recipe calls for a ratio of 2 teaspoons of sesame seeds to 1 teaspoon of pepper flakes, then Omar would need approximately 4/3 teaspoons of toasted sesame seeds for 2/3 teaspoon of pepper flakes.

The joint probability mass function of X and Y, E[X|Y=1] = 2, E[X|Y=2] = 5/2, and E[X|Y=3] = 8/3.If it is true for all values of x and y, then X and Y are independent. Otherwise, they are dependent.

To compute E[X|Y=i], we need to use the formula:

\(E[X|Y=i] = ∑ x*xp(x|Y=i) / P(Y=i)\)

where xp(x|Y=i) is the conditional probability of X given Y=i, and P(Y=i) is the marginal probability of Y=i.

Using Bayes' theorem, we can compute the conditional probabilities xp(x|Y=i) as follows: xp(1|Y=1) = P(X=1,Y=1) / P(Y=1) = (1/9) / (1/9 + 1/3 + 1/9) = 1/3. xp(2|Y=1) = P(X=2,Y=1) / P(Y=1) = (1/3) / (1/9 + 1/3 + 1/9) = 1/3. xp(3|Y=1) = P(X=3,Y=1) / P(Y=1) = (1/9) / (1/9 + 1/3 + 1/9) = 1/3. xp(1|Y=2) = P(X=1,Y=2) / P(Y=2) = (1/9) / (1/9 + 0 + 1/18) = 2/3. xp(2|Y=2) = P(X=2,Y=2) / P(Y=2) = 0 / (1/9 + 0 + 1/18) = 0

xp(3|Y=2) = P(X=3,Y=2) / P(Y=2) = (1/18) / (1/9 + 0 + 1/18) = 1/2. xp(1|Y=3) = P(X=1,Y=3) / P(Y=3) = 0 / (1/9 + 1/6 + 1/9) = 0. xp(2|Y=3) = P(X=2,Y=3) / P(Y=3) = (1/18) / (1/9 + 1/6 + 1/9) = 1/3. xp(3|Y=3) = P(X=3,Y=3) / P(Y=3) = (1/9) / (1/9 + 1/6 +1/9) = 2/3

Using these conditional probabilities, we can compute the conditional expectations E[X|Y=i] as follows: E[X|Y=1] =

\(1*(1/3) + 2*(1/3) + 3*(1/3)\)

= 2

E[X|Y=2] =

\(1*(2/3) + 20 + 3(1/2) = 5/2 E[X|Y=3]\)

=

\(10 + 2(1/3) + 3*(2/3) = 8/3\)

To determine if X and Y are independent, we need to check if the joint probability mass function can be factored into the product of the marginal probability mass functions: p(x,y) = p(x) * p(y)
