If the change in velocity of a car is 30 m/s and the time interval is 5 seconds, the acceleration of the car is ________ m/s2

Answers

Answer 1

The acceleration of the car is 6m/s²

What is acceleration?

Acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. Acceleration is measured in meter per second squared

It can also be defined as the ratio of the change in velocity to the time

Therefore acceleration is given as (v-u)/t

where v is the final velocity and u is the initial velocity, t is the time

therefore a= 30-0/5

a= 30/5

a= 6m/s²

therefore the acceleration of the car is 6m/s²

What is 417 divided by 3 and what is the remainder

Answers

Answer:

139

Step-by-step explanation:

The number 417 divided by 3 gives the quotient of 139 and leaves the remainder of 0.

Given a division problem.

Here, the dividend is 417.

The divisor is 3.

It is required to find the quotient and the remainder of this division problem.

It can be done using the normal division method.

The first term of the dividend is 4.

4 = (3 × 1) + 1

So, the first digit of the quotient is 1.

The remainder, 1, goes to the other digit of the dividend and it becomes 11.

11 = (3 × 3) + 2

The second digit of the quotient is 3.

The remainder 2 goes to the last digit and it becomes 27.

27 = (3 × 9) + 0

The third digit of the quotient is 9.

The remainder is 0.

Hence, the quotient is 139 and the remainder is 0.

Answers

0.8926 is the probability that the shipment will be rejected.

What does the math term "probability" mean?

Probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out.

                              Statistics describes the examination of events subject to probability.

The probability that a digital​ watch is defective p = 10/50 = 0.2

                                                                       n = 10

Using the binomial probability formula

             P(x) = ⁿCₓ pˣ ( 1 - p)ⁿ⁻ˣ

Let x be the random variable that represents the number of defective watches.

The probability that the shipment will be​ rejected

  P(x ≥ 1 ) = 1 - P(0)

               = 1 - ¹⁰C₀ ( 0.2)⁰ ( 0.8)¹⁰

               = 1 - ( 0.8)¹⁰

Provide your answer below:

n =

Answers

Answer: n= 9 and n=11

Step-by-step explanation:

Assume that x is the lesser of the two numbers. The second figure must be x+2.

Since x*(x+2) = 99, we know that

x^2 + 2x - 99 = 0

We obtain x = 11 and 9 by searching for the roots of this equation.

This can also be resolved in the following ways:

We are aware that the two numbers (x and x +2) are consecutive odd numbers. Since x * (x + 2) = x2 + 2x, the value of x must be near to the square root of 99.

The squares 81 and 100 are the ones closest to the number 99. Additionally, we know that x * (x+2) is bigger than x2 (by a factor of 2x), therefore x must equal 9 and x+2 must equal 11.

write polynomial function in standard form with given zeros, x=-2,0,1

Answers

The equation for the polynomial in the standard form is:

P(x) = x^3 + x^2 - 2x

How to find the equation of the polynomial?

A polynomial of degree N with the n zeros {x₁, x₂, x₃, ..., xₙ} is written as:

P(x) = (x - x₁)*(x - x₂)*...*(x - xₙ)

That is called the factorized form of the polynomial, and we are assuming that the leading coefficient is equal to 1 just for simplicity.

In this case we have 3 zeros {-2, 0, 1}, so the polynomial is of degree 3, and we can write it as:

P(x) = (x + 2)*(x - 0)*(x - 1)

To write the polynomial in the standard form, we need to expand the product:

P(x) = (x + 2)*(x)*(x - 1)

P(x) = (x^2 + 2x)*(x - 1)

P(x) = (x^3 + 2x^2 - x^2 - 2x)

P(x) = x^3 + x^2 - 2x

Assume angles 1 and 5 are congruent.

Then lines m and n are parallel by the converse of the corresponding angles theorem.

Lines m and n are not parallel, hence our assumption must be false.

Answers

The straight-line distance between Edentown and Newberg is 90 miles. The correct option is the third option 90 miles

Calculating the straight-line distance between two towns

From the question, we are to determine the possible straight-line distance between Edentown and Newberg if the three towns form a right triangle.

Let the straight-line distance between Edentown and Newberg be x.

Now,

Assume that the straight-line distance between Martville and Newberg is the hypotenuse of the right triangle,

Then,

From the Pythagorean theorem, we can write that

150² = x² + 120²

22500 = x² + 14400

x² = 22500 - 14400

x² = 8100

x = √8100

B. Yes, 80(2.5) = 200, and 200 > 180


C. No, 40(2.5) = 100, and 100 < 180


D. No, 80(0.5)= 40, and 40 < 180

Answers

Answer:

B. Yes, 80(2.5) = 200, and 200 > 180

Step-by-step explanation:1. Addition:

If Serena can paint 40 square feet in 30 minutes, then:

40 + 40 = 80 sq. ft.

30 + 30 = 1 hour

80 + 40 = 120 sq. ft.

60 + 30 = 1.5 hours

120 + 40 = 160 sq. ft.

90 + 30 = 2 hours

160 + 40 = 200 sq. ft.

120 + 30 = 2.5 hours

So, what I just did was adding the 30 minutes and the 40 square feet at the same time until I got to 2.5 hours, and seeing if I also got to 180 square feet. Which I did. I actually got to 200 sq. ft. That means our answer is B. Yes, 80(2.5) = 200, and 200 > 180

Solution:

B. Yes, 80(2.5) = 200, and 200 > 180

Solve the triangle using the Law of Sines. (Assume b and c = 20, and ∠C = 63°. Round the length to two decimal places.)

Answers

Answer:

a = 16.51

angle A = 54

angle B = 63

Step-by-step explanation:

Recall the law of sines:

sinA/a = sinB/b = sinC/c

We know c is 20, and angle C is 63. Since b is also 20, angle B must also be 20. We know have two of the 3 angles, summing to 126, and we can find the last angle from that. 180-126=54, so angle A must be 54.

To solve for a, we need to know the ratio of the other two terms. Sin(63) is around 0.99, and 0.99/20 is 0.049. So we have 0.049=sin(54)/a. To solve for a, we divide by sin(54) and take the reciprocal of both sides, giving a = (sin54)/0.049, which is about 16.51, which is the length of the side a.

Probability is defined as the likelihood of a desired event happening.

Given that: P(A) = 0.37, P(B) = 0.43 and P(AandB) = 0.20.

We want to find P(B | not A)

Remember: P(A | B) = P(A n B) / P(B)

Thus,  P(B | not A) = P(B and not A) / P(not A)

P(not A) = 1 - P(A) = 1 - 0.37 = 0.63

P(B and not A) = P(B) - P(A and B) = 0.43 - 0.20 = 0.23

Hence,

P(B | not A) = P(B and not A) / P(not A) = 0.23 / 0.63 = 0.3651

A two-year-old boy was brought to the emergency department because of vomiting. About 30 minutes prior, he was found by his parents with an open bottle containing ferrous fumarate tablets. The mother estimates about five tablets are missing, and each tablet contains 65 mg of elemental iron. The boy had three episodes of non-bloody vomiting. The physical examination is essentially normal except for tachycardia. Which of the following is the next best step?get serum iron level four hours after ingestionThe patient has symptoms and a history compatible with iron toxicity. The severity of an exposure is related to the amount of elemental iron ingested. Ferrous sulfate contains 20 percent elemental iron, ferrous gluconate has 12 percent, and ferrous fumarate contains 33 percent. Iron is directly corrosive to the GI mucosa, which can lead to hematemesis, melena, ulceration, infarction, and potential perforation. For significant ingestions (> 20 mg/kg of elemental iron), especially when tablets are identified on the abdominal radiograph, whole-bowel irrigation with a polyethylene glycol electrolyte lavage solution (PEG-ELS) is routinely recommended. Iron toxicity is described in four stages. The initial stage, 30 minutes to six hours after ingestion consists of profuse vomiting and diarrhea, abdominal pain, and significant volume losses, leading to potential hypovolemic shock. The second stage, six to 24 hours after ingestion, is the quiescent phase where GI symptoms typically resolve. In the third stage, occurring 12 to 24 hours after ingestion, patients develop multi-system organ failure, shock, hepatic and cardiac dysfunction, acute lung injury, and profound metabolic acidosis. Symptomatic patients and patients with a large exposure by history should have serum iron levels drawn four to six hours after ingestion. Serum iron concentrations of < 500 g/dL four to eight hours after ingestion suggest a low risk of significant toxicity, whereas concentrations of > 500 g/dL indicate significant toxicity.

It is simple:t=(V-V_0)/a=(8-2)/2=3(s).This is the answer. Note that it is important that the initial velocity and the final velocity have the same direction (west). If they would have opposite direction, one of them should be taken with a minus sign, and the acceleration might be negative. 2.
