if f(x)=2x and g(x)=x^2-1 which statement is true?
A. (f*g)(x)=2x^2 -1
B.(f*g)(x)=2x(x^2-1)
C.(g*f)(x)=4x-1
D.(g*f)(x)=4x^2-1

Answers

Answer 1
For this case, the first thing we must do is multiply both functions to obtain the desired result.
 We have then:
 f (x) = 2x
 g (x) = x ^ 2-1
 Multiplying we have:
 (f * g) (x) = (2x) * (x ^ 2-1)
 Answer:
 
The following statement is correct:
 B. (f * g) (x) = 2x (x ^ 2-1)

how many solutions 2x+3y=-3 and 3x + 5y = -9

Answers

Since the slopes of the two lines are the not equal, they will have only one solution. The solution will be a point and can be found using the method given below.

We can find the solutions by simultaneously solving the two equations.

From first equation, the value of y comes out to be:

[tex]2x+3y=-3 \\ \\ 3y=-3-2x \\ \\ y= \frac{-3-2x}{3} [/tex]

Using this value of y in second equation, we get:

[tex]3x+5( \frac{-3-2x}{3} )=-9 \\ \\ 9x-15-10x=-27 \\ \\ -x=-27+15 \\ \\ -x=-12 \\ \\ x=12[/tex]

Using this value of x, we can find y:

[tex]y= \frac{-3-2x}{3}= \frac{-3-24}{3} =-9 [/tex]

Therefore, there is only one solution to the given equations is which is (12, -9)

Thank you for coming to Brainly with your questions!

I believe the answer is:

A. 2 cm. because to find the area of the rectangle, you multiply length times width, so to find what the length is, you divide the width by the area, which is 2 cm.

Identify the variable and the categories represented in this problem. Set up and fill in a two-way table to represent the frequencies in this problem.

Answers

Part a) 
Identify the variable and categories


By reading the above statement, we can find that there are two variables and each variable has 2 categories. The variables and their categories are:
1) Class Number
This variable is further divided into 2 categories i.e. Class 9th and Class 10th.

2) Participation in Extracurricular activities
This variable is further divided into 2 categories based on if students participated or not.

Part b)
Set up and fill 2 way table.

Since, we have 2 variables and each variable has 2 categories the number of data cells will be 2 x 2 = 4 cells

There are total 100 students. 40 students are in class 10th. This means 60 students are in class 9th.Out of 40 students in class 10th, 18 students participate in at least one extracurricular activity. So remaining 22 students do not participate. 32 students from class 9th participate in extracurricular activities, this means the remaining 28 students do not participate. Based on this data, we can fill up the table as shown below
 

A 60 kg dog requires fluids at 50 mL/kg over 24 hours. Using a 10 gtt/mL set how many gtts/min will you set?

Answers


[tex] 50\times 10 = 500[/tex]
[tex]60 \times 24 = 1400 \: mins[/tex]
500/1400= .36gtts per min

To set the infusion rate for a 60 kg dog, calculate the total fluid needed (3000 mL), the total number of drops (30,000 gtts), and then determine the drops per minute (20.83 gtt/min), rounding to approximately 21 drops per minute.

To calculate the infusion rate for a 60 kg dog that needs 50 mL/kg of fluids over 24 hours using a 10 gtt/mL set, follow these steps:

Firstly, calculate the total volume of fluids required by the dog:
60 kg x 50 mL/kg = 3000 mL.Next, determine the total number of drops needed since the set delivers 10 drops per mL:
3000 mL x 10 gtt/mL = 30,000 gtts.Calculate the number of drops per minute by dividing the total number of drops by the number of minutes in 24 hours (1440 minutes):
30,000 gtts / 1440 minutes = 20.83 gtts/minute.

Therefore, you will set the infusion to approximately 21 drops per minute (rounding to the nearest whole number).

The no. of equally likely event is 10.

What is probability ?

Probability is chance of occurrence of a certain event out of all the possible events that can occur in a given situation.

According to the given question Tossing of four coins simultaneously as an experiment let us find he sample space and assuming that all these 4 coins are unbiased.

S = { HHHH, HHHT, HHTT, HTTT, TTTT, TTTH, TTHH, THHH, HTTH, THHT }.

A triangle shaped paper’s height is 18 cm and width is 10 cm. Find the hypotenuse of the paper.

Answers

The hypotenuse is 20.59. 10^2+18^2=C^2

The hypotenuse of the paper is 2√106 cm.

What is Pythagorean theorem ?

Hypotenuse ² = Height ² + Width ²

Know more about Pythagorean theorem,

The Pythagorean Theorem, also known as the Pythagoras Theorem, explains the relationship between the three sides of a right triangle. According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a right triangle. Pythagorean triangles are the name given to the sides of a right triangle. Let's learn about Pythagorean theorem, formula, derivation and examples in detail.

The history of the Pythagorean theorem goes back to the ancient Babylonian and Egyptian era. The Greek mathematician Pythagoras of Samos introduced the Pythagorean theorem. Pythagoras was born in 570 BC. The Greek philosopher studied with other monks and formed a group of people; he finally stated the Pythagorean theorem. Even before Pythagoras, the ratio was shown on a Babylonian tablet 4000 years ago, but the theorem is published under the name of Pythagoras.

Here given, a triangle shaped paper’s height is 18 cm and width is 10 cm.

We want find the hypotenuse of the paper ?

Here, height of the paper = 18 cm and width of the triangle = 10 cm.

[tex] = {18}^{2} + {10}^{2} \\ = 324 + 100 \\ = 424[/tex]

So,

[tex]hypotenuse = \sqrt{424} \\ = \sqrt{2 \times 2 \times 2 \times 53} \\ = 2 \sqrt{2 \times 53} \\ = 2 \sqrt{106} \: cm[/tex]

Therefore,the hypotenuse of the paper is 2√106 cm.

Find the number that is smaller than 5 5/12 by as much as 2 2/13 is smaller than 6 1/6

Answers

Answer: the number is x = 1 + 21/52

Step-by-step explanation:

we have

(5 + 5/12) - x = (6 + 1/6) - (2 + 2/13)

this means that x is smaller than 5 + 5/12 by the same amount as (2 + 2/13) is smaller than (6 + 1/6)

We can solve it directly, first solve the parentheses, put the whole numbers at one side and the fractions in the other side:

5 - 6 + 2 - x = -5/12 + 1/6 - 2/13

1 - x = -5/12 + 2/12 - 2/13

1 - x = -3/12 - 2/13 = -1/4 - 2/13 = -13/(4*13) - (2*4)/(4*13) = -21/52

x = 1 + 21/52

Answers

Answer:

Description:

The basket ball shoots from a height of 6 feet, it increase the height 1.5 feet after 1.5 seconds.

Therefore, the basketball thrown at the rate of 1 feet/per second.

Step-by-step explanation:

Given: A player shoots a basketball from a height of 6 feet. The equation,

h(t) = [tex]-16t^2 + 25t + 6[/tex]

We need to find the height of the ball when t = 1.5 and describe the height.

plug in t = 1.5 in h(t) = [tex]-16t^2 + 25t + 6[/tex]

h(1.5) = [tex]-16(1.5)^2 + 25(1.5) + 6[/tex]

Simplifying the above expression, we get

h(1.5) = -36 + 37.5 + 6

h(1.5) = -36+43.5

h(1.5) = 7.5 feet

The height of the ball after t =1.5 second is 7.5 feet

Description:

The basket ball shoots from a height of 6 feet, it increase the height 1.5 feet after 1.5 seconds.

Therefore, the basketball thrown at the rate of 1 feet/per second.

Explain how you know 21/100 is greater than 1/5

Answers

This problem can be solved using equivalent fractions. The first step in resolving this problem is to realize that fractions are best compared when they both have the same denominator.  In this case, I will choose to make that common denominator 100. There is no need to rewrite the fraction [tex]\frac{21}{100}[/tex] as the denominator for this fraction is already 100. The fraction [tex]\frac{1}{5} =\frac{20}{100}[/tex] . This is achieved by multiplying both the numerator and denominator by 20. Now that the two fractions have the same denominator, we can easily see that [tex]\frac{21}{100}[/tex] is greater than [tex]\frac{1}{5}[/tex] because it is greater than its equivalent fraction.
