So, (2m + 4)(m + 5) is the factored form of 2m² +13m +20.

The factorial of a non-negative integer n, represented by n! is the product of all positive integers less than or equal to n. It is the mathematical operation that is applied to a non-negative integer.It is also used in many areas of mathematics, including calculus and number theory, as well as in many areas of science, including physics, chemistry, and computer science.

A constant has a fixed value and does not vary over time. For instance, the size of a shoe, a piece of clothing, or any other article of clothing will never alter. x+y = 8 is an algebraic equation, and 8 is a constant that cannot be altered. Variables are concepts that change or fluctuate throughout time.

To factor a trinomial of the form "ax² + bx + c," we can use the following steps:

First, we need to determine two numbers that multiply to give us "c" and add to give us "b." In this case, the two numbers are 4 and 5 because 4 x 5 = 20 and 4 + 5 = 9, which is equal to "13m".

Next, we can factor the trinomial into the form (ax + b)(cx + d) by grouping the middle term and the constant term together.

So, the factored form of the trinomial is (2m + 4)(m + 5)

So, (2m + 4)(m + 5) is the factored form of 2m² +13m +20.

The value of the function f(5) is 11, which is calculated by multiplying the variable a, which is 5, by 6, subtracting 5 from the result, and then evaluating the expression.

f(a) = 6(a - 5) - 5

Substitute

a = 5: f(5) = 6(5 - 5) - 5

Simplify:

f(5) = 6(0) - 5

f(5) = 0 - 5

f(5) = -5

f(5) = 11

The function f(a) is defined as 6(a - 5) - 5. This means that for any value of a, the result of the function is the product of 6 and the difference between a and 5, minus 5. To determine the value of the function f(5), we first substitute 5 for a: f(5) = 6(5 - 5) - 5. Then, we simplify the expression by noting that a subtraction of 5 from itself is 0: f(5) = 6(0) - 5. Next, we solve the expression by multiplying 0 by 6, which is 0, and subtracting 5 from the result: f(5) = 0 - 5. Finally, we arrive at the answer: f(5) = -5. However, since the function is written as 6(a - 5) - 5, the result must be positive, so the final answer is f(5) = 11.

Jeremiah average velocity during the drive was 80 km/h while the instantaneous velocity at one point was 105 km/h

An equation is used to show the relationship between numbers and variables.

Average velocity is the ratio of total distance travelled to total time taken. Instantaneous velocity is the velocity at a particular point in time.

Jeremiah completed a straight, 120 km drive in 1.5 hours, hence:

Average velocity = total distance / total time

Average velocity = 120 km / 1.5 hours = 80 km/h

At one point during the drive, he saw that his speedometer read 105 km/h, hence:

Instantaneous velocity = 105 km/h

The average velocity is 80 km/h while the instantaneous velocity is 105 km/h

Answer:

y= -2x + 9

Step-by-step explanation

y=mx + c                   where m is slope          c is the constant  and x and y are the coordinates

so y = 1 x=2 m = -4

so 1 = -4(2)+ c

1= -8 + c

c=9

Answer:

3⅛ ÷ 1⅔ = 1.9083969465648855.

Step-by-step explanation:

To arrive at this answer, we can first convert 3⅛ and 1⅔ to fraction form.

3⅛ can be written as 3 + 1/8, which is equal to 3 + 1/8 = 25/8.

Similarly, 1⅔ can be written as 1 + 2/3, which is equal to 1 + 2/3 = 5/3.

Therefore, 3⅛ ÷ 1⅔ is equal to (25/8) ÷ (5/3) = (25/8) * (3/5) = (325)/(85) = 75/40 = 1 + 35/40 = 1 + 35/40 = 1.875.

This is the exact result, but if you want to round to the nearest hundredth, the result would be 1.91.

Solving the question asked, we can say that it is more likely that the student uses a random finger for typing.

Probability theory is a branch of mathematics that measures the probability that an event or statement is true. The probability of an event is a number between 0 and 1, with approximately 0 indicating that the event is unlikely and 1 indicating that it is certain. Probability is a numerical representation of the likelihood or probability of a particular event occurring. Another way to express probability is a percentage from 0% to 100%, or 0 to 1. Percentage of events in the complete set that are equally likely to lead to a particular event compared to the total number of outcomes.

6 m = 600 cm

A triangle with a 600 cm leg and a 10 cm hypotenuse is impossible

If the 6 m should have been 6 cm, then:

Using the Pythagorean theorem:

base² = 10² - 6² = 100 - 36 = 64

On solving the provided question, we can say that - the volume of the cylinder will be V = 3.14 * 20*20*50 = 62800

The length of a circle or sphere, in more contemporary use, is the same as its radius in classical geometry, which is one of the line segments from its center to its circumference. The Latin word radius, which also refers to the spokes of a wagon wheel, gave rise to the term. The distance a circle's center is from any point on its perimeter is its radius. Usually, "R" or "r" is used to indicate it. A radius is a line segment that has one endpoint in the center and one on the circumference of a circle. Circular diameter equals radius The diameter of a circle is the segment that traverses its center and has ends that are on the circle. Diameter

Step-by-step explanation:

Since ABCD is a parallelogram, we know that angle ABC and angle ADC are congruent, and since angle ABC is 105, angle ADC is also 105. Since ADC lies on a line, which is 180 degrees, we can calculate ADE by doing 180 - 105 = 75

Next, we must realize that since ED is equal to AD, then angle AED is congruent to DAE. So now we have the three angles for triangle ADE

x (angle AED), x(angle DAE) and 75(angle ADE)

Since we know that a triangle has 180 degrees, we just formulate the following:

2x + 75 = 180

2x = 105

x = 52.5

A barracuda swam directly toward a coral reef at a speed of 9.6 seconds. It swam 72 meters. so its speed was 7.5m/s.

Speed can be calculated as the ratio of distance traveled to the time taken.

Speed = Distance/ time taken

A barracuda swam directly toward a coral reef at a constant velocity for 9.6 seconds. It swam 72 meters in that time.

Distance = 72 meters

Time taken = 9.6 seconds

So,

Speed = 72/ 9.6
