Find the zeros of the quadratic equation y=4(x+9)²-36

Therefore , the solution of the given problem of unitary method comes out to be Daisy cream and Kremlin cream both have less cream per bulk 1 gallon and 4.5 gallons, respectively than Marble cream.

The objective can be accomplished by utilising what has already been discovered, taking advantage of this worldwide access, and including all essential components from earlier changeable study who employed a certain technique. If the anticipated claim outcome actually occurs, it will either be possible to contact the variable again or both important processes will undoubtedly miss the statement.

Here,

We must convert cups to gallons because daisy cream is sold in bulks of cups. Since a gallon of Daisy cream comprises 16 cups, one quantity of Daisy cream contains:

=> 16 cups per bulk = 1 gallon 16 cups per bulk = 1 gallon

Moscow cream is offered in bulk quantities of 4 1/2 gallons, which is one gallon.

Thus, we must convert pints to gallons. A gallon of Marble cream comprises eight pints, hence one quantity of Marble cream contains:

=> 40 pints in a bulk equal 1 gallon, 8 pints, or 5 gallons.

As a result, we can see that Marble cream, with 5 gallons per bulk, has the most cream.

Daisy cream and Kremlin cream both have less cream per bulk (1 gallon and 4.5 gallons, respectively) than Marble cream.

The expression which can be used to find the solutions of the given equation is option (a) [5 ± √81] / 4.

Quadratic equations are polynomial equations of second degree.

The general form of a quadratic equation is ax² + b x + c = 0.

The given quadratic equation is,

2x² - 5x - 7 = 0

The solutions of a quadratic equation can be found using the quadratic formula.

Quadratic formula for ax² + b x + c = 0 is,

x = [-b ± \(\sqrt{b^2-4ac}\) ] / 2a, where \(\sqrt{b^2-4ac}\) is called discriminant.

From the given equation,

a = 2, b = -5 and c = -7.

Solution can be found as,

x = -(-5) ± \(\sqrt{(-5)^2-(4*2*-7)}\) ] / (2 × 2)

  = [5 ± √(25 + 56) ] / 4

  = [5 ± √81] / 4

Hence the solution can be found as [5 ± √81] / 4.

Answer:A unique line is defined by any two distinct (not identical) points. You have two distinct, which means you have a line. To find the equation for the line, we start with the slope-intercept equation for a line. This is only a template for a generic line, so we will have to find the specific values of m (slope) and b (y-intercept) that define your line.

The template: y = mx + b

b is the y-intercept, which, if you look at (0,–2), you will see is –2; it is where the line crosses the y-axis. Fill that value of b into our template to get:

y = mx – 2

Now, we only need the value of m, which is the slope. If you have two points on a line, you can calculate the slope of that line. The slope is the change (difference) of y over the change in x (difference) of x for two given points on the line. It's a fraction or ratio though sometimes it can be reduced to an integer.

So, taking your two points, you calculate the slope, m, in the following way:

(x1,y1) = (0,–2)

(x2,y2) = (5,1)

        y2 – y1                   1 – (–2)                1 + 2               3

m = ________   =     ________    =     ________  =    ____

Using proportions, it is found that the total amount budgeted for entertainment is of $720.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

Researching the problem on the internet, it is found that the day trip amount is 10% of the budget for entertainment, hence:

0.1x = 72

x = 72/0.1

x = 720.

Hence the total amount budgeted for entertainment is of $720.

Answer:

56

Step-by-step explanation:

Ration of the no. of women to men = 4 : 5

= 9x = 126 = 14

Thus no. of women = 4 × x = 4 × 14 = 56

According to the binomial distribution, there is a 0.128 = 12.8% chance that it will take her precisely 3 pushes to start the mower.

It has a 20% chance of starting on any given pull, therefore

Item

a:This probability is P(X = 0) when n = 2, multiplied by 0.2, which is the probability that it starts on the third, and it is that it doesn't start on the first two. Hence:

It has a 0.128 = 12.8% chance that she starts the mower with exactly 3 pulls.

Item b:When n = 10, this probability is none on the first 10 and is hence P(X = 0):

Her chances of needing more than 10 pushes to start the mower are 0.1074, or 10.74%.

It has a 0.128 = 12.8% chance that she starts the mower with exactly 3 pulls.

Item b:On the first, there is no chance in this.

Bakers A, B, C work in a bakery, where 75% of the cookies are baked by A, 20% are baked by B, and 5% are baked by C.

P(Cookies with Hair) = P(From A) + P(From B) + P(From C)

P(Cookies with Hair) = (0.75X0.05) + (0.20X0.20) + (0.05X0.60)

P(Cookies with Hair) = 0.1075

In Percentage,

P(Cookies with Hair) = 10.75%

Proportion of the cookies from this bakery contains hair is 10.75%

If a cookie contains hair, the probability that it was baked by C is

P(From C given that it Contains Hair) = P(C|H)

P(H|C) = P(Cookie from C) | P(Contains Hair)

P(H|C) = P(Cookie from C and Contains Hair) / P(Contains Hair)

P(H|C) = P(C ∩ H)/P(H)

P(H|C) = (0.05X0.60)/(0.75X0.05) + (0.20X0.20) + (0.05X0.60)

P(H|C) = 0.2791

In Percentage,

P(From C given that it Contains Hair) = 27.91%

If A and B are similar matrices and v is an eigenvector of A, then v is also an eigenvector of B , similarly if u is an eigenvector of B then u is also eigenvector of A.

Suppose A and B are n×n matrices over R or C. We say A and B are similar, or that A is similar to B, if there exists a matrix P such that B =P⁻¹AP.

The eigenvalues are the roots of the

characteristic polynomial.

B =P⁻¹AP ⇔ PBP⁻¹ = A

If Av = λv , then PBP⁻¹v = λv ⇒ BP⁻¹v = P⁻¹λv

So, if v is an eigenvector of A, with eigenvalue λ, then P⁻¹v (which is non-zero since P is invertible) is an eigenvector of B with the same eigenvalue. If u is an eigenvector for B then P⁻¹v is an eigenvector for A. So, every eigenvalue of A is an eigenvalue of B and since you can interchange the roles of A and B in the previous calculations, every eigenvalue of B is an eigenvalue of A too. Hence, A and B have the same eigenvalues.

Answer and Step-by-step explanation:

To find out how many more yards of red fabric Reuben used, we need to subtract the amount of yellow fabric from the amount of red fabric. Since the two fractions have different denominators, we need to find a common denominator before subtracting them. The least common multiple of 8 and 4 is 8, so we can rewrite both fractions with a denominator of 8:

7/8 - 1/4 = 7/8 - (1/4) * (2/2) = 7/8 - 2/8 = (7 - 2)/8 = 5/8

So, Reuben used 5/8 yards more red fabric than yellow fabric.

After the pumping, Container B is 11.8\%11.8% empty.

Step-by-step explanation:

The volume of water inside Container B equals the entire volume of Container A. The empty portion of Container B is equal to the entire volume of Container B minus the volume of water inside Container B. So the volume of empty space inside Container B is equal to 1570.7963-1385.44241570.7963−1385.4424 which equals 185.3539.

Answer:

\(t = 1.45\) or \(t = 0.86\)

Step-by-step explanation:

Given

\(h=3+37t-16t^2\)

Required

Find all values of t when height is 23 feet

To solve this, we simply substitute 23 for h

\(23=3+37t-16t^2\)

Collect  like terms

\(16t^2 - 37t - 3 + 23=0\)

\(16t^2 - 37t +20=0\)

Solve t using quadratic formula;

\(t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}\)

Where a = 16, b =-37 and c = 20

\(t = \frac{-(-37)\±\sqrt{(-37)^2 - 4*16*20}}{2*16}\)

\(t = \frac{37\±\sqrt{(-37)^2 - 4*16*20}}{2*16}\)

\(t = \frac{37\±\sqrt{1369 - 1280}}{32}\)

\(t = \frac{37\±\sqrt{89}}{32}\)

\(t = \frac{37\±9.43}{32}\)

\(t = \frac{37+9.43}{32}\) or \(t = \frac{37-9.43}{32}\)

\(t = \frac{46.43}{32}\) or \(t = \frac{27.57}{32}\)

\(t = \frac{46.43}{32}\) or \(t = \frac{27.57}{32}\)

\(t = 1.45\) or \(t = 0.86\)

The probability is P = 0.135

First, we need to find the individual probabilities, that are given by the quotient between the number of outcomes that meet the condition and the total number of outcomes.

The joint probability is given by the product between the individual probabilities, so we get:

P = (1/2)*(3/6)*(28/52) = 0.135
