Which ratio is equal to the number π

Mathematics
1 answer:
Blizzard [7]4 years ago
7 0

Answer: 3.14

Step-by-step explanation:

Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle's size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14.

What is the volume of this rectangular prism?
salantis [7]

Answer:

1cm³

Step-by-step explanation:

You do not need a calculator for this.

The formula for the volume of a rectangular prism is:

Length × Width × Height = Volume

If we substitute our numbers in:

5/4 × 4/3 × 3/5 = 1cm³

All you need to do is multiply across.

5 × 4 × 3 = 60

4 × 3 × 5 = 60

The numerator and denominator both equal 60. So the fraction would look like this if you were to keep it as a fraction.

60/60

Which of the following sets contain all roots of the polynomial
Zarrin [17]

All these given roots are contained in option C.

The given equation is :

9x^{3}+9x^{2}-4x-4=0

9x^{2}(x+1)-4(x+1)=0

(9x^{2}-4)(x+1)=0

9x^{2}-4=0,x+1=0

x^{2}=\frac{4}{9},x=-1

x=\frac{2}{3},x=-1

Roots = -1,\frac{-2}{3} ,\frac{2}{3}

Hence these lie in between (\frac{-3}{2} ,\frac{3}{2})

Gerald graphs the function f(x) = (x – 3)2 – 1. Which statements are true about the graph? Select three options.
Phoenix [80]

Answer:

The answer is "Choice B, C, and F is correct".

Step-by-step explanation:

The following are choices, which is missing in the question, that can be defined as follows:

A) {x| x ≥ 3} is the domain.  

B) The set shall be {y| y ≥ –1}.  

C) over the interval  (–∞, 3), is the function, that decreases.  

D) it's over the duration the function increases its value, that is (–1, ∞).  

E) The symmetry axis will be x = – 1.  

F) vertex is (3, – 1).

  • In choice A, It is incorrect even though f is the domain, which is all true numbers because it has a quadrant function.  
  • In choice B, it is correct.  
  • In choice C, It is valid because it was a parable open with vertex so if we exploded view f (3, -1). Because as value opens up, its value with x from-∞ to 3 drops while it goes up from increasing from 3 to ∞.    
  • In choice D, It is wrong since we have just said f decreases from-∞ to 3. Therefore, f decreases from -1 to 3, too. Therefore, f doesn't grow from -1 to ∞.  
  • In choice E, It is incorrect because the symmetry axis is x = 3.  
  • In choice F, it is true.

−t=9(t−10)<br><br><br> pls show work too thank u so much
Andreas93 [3]

Answer:

t = 9

Step-by-step explanation:

Step 1:

- t = 9 ( t - 10 )          Equation

Step 2:

- t = 9t - 90       Multiply

Step 3:

- t + 90 = 9t        Add 90 on both sides

Step 4:

90 = 10t      Add t on both sides

Step 5:

t = 90 ÷ 10       Divide

Answer:

t = 9

Hope This Helps :)

What is another point on the line?
Kamila [148]

Answer:

B. (0,9)

Step-by-step explanation:

Start the point on (4,3), and becasue the slope is -3/2 you do rise over run. so you could go up 3 and left 2 or down 3 and right 2. i went up 3 and left to twice from point (4,3) and arrived at point (0,9). so the answer is B. (0,9)
