[x² + y² =9
+²-1
A. System of nonlinear equations
B. System of linear inequalities
C. System of nonlinear inequalities
D. System of linear equations

Answer:

21 units

Step-by-step explanation:

Answer:

\(y = - 3x - 5 \\ c = - 5\)

For your first answer it is because they are two different ways to solve the equation

For Example!

(x-4)² – 28 = 8The 8 is positive making it a different equation (this is like absolute value). (I am assuming you know the answer to the probelm)

(x-4)² – 28 = -8

The 8 could be negative meaning that when you add the 28 to the right side it is -8+28 which will be a negative!

Answer:

This is because it is a quadratic equation.

It can therefore be solved using either factorization method or completing of squares method.

the factorization method has been worked above.

The expression becomes: p^(1/2) = p^(1/2 * 1) = p^(1/2) Now we can simplify p^(1/2) as p^1/2 which equals the square root of p.

The property of exponents that must be applied to the expression p^(1/2) to derive p as the result is the Power of a Power Property.

The Power of a Power Property states that when a power is raised to another power, the exponents are multiplied.

For instance, consider the expression p^(1/2). We can apply the Power of a Power Property to this expression as follows: p^(1/2) = (p^(1/2))^1 By applying the Power of a Power Property, the exponent (1/2) is multiplied by the exponent 1, giving a result of 1/2.

Therefore, the expression becomes: p^(1/2) = p^(1/2 * 1) = p^(1/2)Now we can simplify p^(1/2) as p^1/2 which equals the square root of p.

So we have derived p as the result using the Power of a Power Property.

In summary, we must apply the Power of a Power Property to the expression p^(1/2) to derive p as the result.

Answer:

Johnny needs to score 98 on third test to raise average to 94

Step-by-step explanation:

Given that average of two tests is 92.

The score of next test has to be found that means there will be a total of 3 tests.

The average will be:

\(Avg = \frac{test1+test2+test3}{3}\)

It is also given that he has to raise his average to 98

We have to use the average formula for finding the third value

So,

\(94 = \frac{92+92+test3}{3}\\94*3 = 184+test3\\282 = 184+test3\\test3 = 282-184\\test3 = 98\)

Hence,

Johnny needs to score 98 on third test to raise average to 94

Answer:

Johnny would need to get a 98

Step-by-step explanation:

You would need to use the average formula and see what it would be eual to.

The product of the numbers 2.7 x 6.4 using partial products is 17.28

In order to get the product of the values using partial products, we will use the concept of repeated addition as shown:

2.7 x 6.4

For 2.7 = 2.0 + 0.7

6.4 = 6.0 + 0.4

Substituting the sum into the product, we will have:

2.7 x 6.4 = (2.0 + 0.7)  x (6.0 +0.4)

2.7 x 6.4 = 2.0(6.0) + 2(0.4) + 0.7(6) + 0.7(0.4)

2.7 x 6.4 = 12 + 0.8 + 4.2 + 0.28

2.7 x 6.4  = 17.28

Therefore, the value is 17.28.

The genotype must be Rr and rr because the outcome is close to the 1:1 ratio of red to white flowering plants.

According to Mendel's law of dominance, one feature in a heterozygote will mask the existence of another trait for the same attribute. The dominant allele will be exclusively expressed, as opposed to both alleles contributing to a trait.

When parents with distinct, opposing qualities are crossed, only one form of the trait manifests itself in the offspring, according to Mendel's law of dominance. Only the dominant phenotypic characteristic will be present in the hybrid offspring. The first law of inheritance is the dominance principle.

This regulation states that the first generation of offspring from purebred parents shall exhibit solely dominant features.

There will be a 1:1 ratio between the dominant and recessive traits when a heterozygous dominant parent mates with a pure recessive parent.

The cross:

           r            r

R         Rr          Rr

r          rr           rr

The genotype must be Rr and rr since the outcome is close to the ratio of red to white flowering plants.

Therefore, the correct answer is option A. The result is close to the 1:1 ratio of red to white flowering plants, so the genotype must be Rr and rr.

The complete question is:

A cross between a plant with red flowers (R = dominant) and a plant with white flowers (r = recessive) yielded 47 plants with red flowers and 51 plants with white flowers. What are the genotypes of the parent plants? Explain

A. The results are close to a 1:1 ratio of plants with red flowers to plants with white flowers. Therefore, the genotypes of the Rr and ir

B. The results should yield plants with red flowers and plants with white flowers in a 3:1 ratio due, so the genotype of each parent is Rr. The number of offspring was not large enough to produce the expected results

C. The results differ from the predicted values. Therefore, the genotypes of the parents cannot be determined.

D. The results should show a ratio of 3 plants with white flowers to 1 plant with red flowers, so the genotypes of the parent plants are RR and rr.

Step-by-step explanation:

Use the midpoint formula to find the midpoint of the line segment.

Answer

t = ln (2.3) / 2

Explanation:

y(t) = 40 e^2t + 8

Let y(t) = total population within a time frame

According to the question, y(t) = 100

100 = 40 e^2t + 8

Collect the like terms

100 - 8 = 40 e^2t

92 = 40 e^2t

Divide both sides by 40

92/40 = 40 e^2t / 40

2.3 = e^2t

Take the natural logarithms of both sides

ln (2.3) = ln (e^2t)

ln (2.3) = 2t

Divide both sides by 2

ln (2.3) / 2 = 2t / 2

t = In (2.3) / 2 in terms of the natural logarithms

t = 0.8329 / 2

t = 0.4 mins

Given that 16 families went on a trip and the cost of the trip was Rs. 2,16,352.The amount paid by each family is to be determined by unitary method Hence each family paid Rs.13522

Now, let's solve this by using the method of unitary method. To find the cost of 1 family trip, we will divide the total cost of the trip by the number of families.2,16,352 / 16 = 13,522 So, the cost of the trip per family is Rs. 13,522.Hence, each family paid Rs. 13,522 for the trip.

to know more about unitary method

https://brainly.com/question/28276953

Answer:

Step-by-step explanation

1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.

Now let's check if this result is correct:

1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.
2. This is exactly the same as the total cost given in the problem statement.

So we have shown that each family paid **Rs 13,522** for the trip

The probability of someone pulling 1-10 in consecutive order from a bad that contains 10 balls labelled 1-10 is 1/3628800.

An event's probability is a numerical representation of how likely it is that the event will take place. In mathematical notation, it is written as a number between 0 and 1, or as a percentage between 0% and 100%. The higher an event's probability, the more likely it is to occur.

In a sample space, there is a probability of 1 for each event. The probability formula states that the ratio between the number of favourable outcomes and the total number of outcomes determines the likelihood that an event will occur. Sets are used in the terminology of probability theory. A set is a grouping of various things.

It is said that there are 10 balls in a bag, labelled 1-10.

Now,

The number of ways the ball labelled 1 is picked is 1

The number of ways the ball labelled 2 is picked is 2

So the number of ways a ball labelled certain number is picked is 1.

Now there is no replacement.

So the total number of balls decreases by 1 when 1 ball is taken.

Then,

The probability of choosing the ball numbered 1 = 1/10

The probability of choosing 2 = 1/9

The probability of choosing 3 = 1/8

.

.

.

the probability of choosing 10 = 1

Total probability of choosing the balls in consecutive order = 1/10 * 1/9 * 1/8 *.......* 1/2*1/1 = 1/10! = 1/3628800.

Therefore the probability of someone pulling 1-10 in consecutive order from a bad that contains 10 balls labelled 1-10 is 1/3628800.
