What is the ratio of the radius to the circumference of any circle, using 3.14 for pi?
Answer:
1 : 6.28Step-by-step explanation:
The circumference formula is
C = 2πr orC = 2(3.14)r = 6.28rThe ratio of the radius to the circumference is
r/C = 1/6.28or
r : C = 1 : 6.28r : C = 1 : 6.28
Formula's:
circumference of any circle: 2πr
radius: r
Their ratio:
radius : circumference
r : 2πr
r : 2(3.14)r
1 : 6.28
Elizabeth bought a cheese pizza. It was served on a metal tray with a diameter of 22 centimeters. What is the tray's area?
The Area of the tray ≈380 cm
Solution:We are given the diameter of the tray, which is equivalent to 22 cm.We are asked to find the area of the tray.Remember the formula:Area of a circle = πr²Whereπ -> pi (3.14...)r -> radiusNotice that we aren't given the radius. We're given the diameter only.No reason to panic. We can easily find the radius by dividing the diameter by 2.The radius is equal to 11 cm.Now, plug the values into the formula:A=π(11)²A=121πA≈380 cmHope it helps.

Find the slope of the line passing through the points , 2−6 and , −9−6
I will assume that we are trying to find the slope between (2,-6) and (-9,-6)
The slope's equation ⇒ [tex]\frac{y2-y1}{x2-x1}[/tex]
Let's set the variables:
(x1, y1) --> (2, -6)
(x2, y2) --> (-9, -6)
Now let's plug them in:
[tex]Slope = \frac{-6--6}{-9-2} =\frac{0}{-11} =0[/tex]
Thus the slope of the line is 0.

Laurie throws a tennis ball toward her dog from a height of 4.5 ft. The initial vertical velocity of the ball is 18 ft/s. At the same time as Laurie throws the ball, her dog jumps with an initial vertical velocity of 21 ft/s. When the dog jumps, its mouth is 1.5 ft above the ground.
Projectile motion formula:
h = -16t2 + vt + h0
t = time, in seconds, since the ball was thrown
h = height, in feet, above the ground
Which system models the height of the tennis ball and the height of the dog's mouth over time?
h = 4.5t + 18 and h = -16t2 + 1.5t + 21
h = 18t + 4.5 and h =-16t2 + 21t + 1.5
h = -16t2 + 4.5t + 18 and h = -16t2 + 1.5t + 14
h = -16t2 + 18t + 4.5 and h = -16t2 + 21t + 1.5
Using quadratic function concepts, it is found that the system that models the height of the tennis ball and the height of the dog's mouth over time is given by:
h(t) = -16t² + 18t + 4.5 and h(t) = -16t² + 21t + 1.5.
What is the quadratic function for the height of a projectile?It is given by:
h(t) = -16t² + v(0)t + h(0)
In which:
v(0) is the initial velocity.h(0) is the initial height.For the tennis ball, we have that v(0) = 18, h(0) = 4.5, hence the equation is:
h(t) = -16t² + 18t + 4.5.
For the dog jump, we have that v(0) = 21, h(0) = 1.5, hence:
h(t) = -16t² + 21t + 1.5.
Hence, the system is given by:
h(t) = -16t² + 18t + 4.5 and h(t) = -16t² + 21t + 1.5.

Answer:
D) h = -16t2 + 18t + 4.5 and h = -16t2 + 21t + 1.5

I hate math. Can someone pls help me?
Answer:
∠s = 158
Step-by-step explanation:
Since lines a and b are parallel,
∠s and 158 are alternate exterior angles.
Alternate exterior angles are equal if two lines are parallel.
So,
∠s = 158
Answer: 22°.
Step-by-step explanation: We're given the angle 158°, which is all we need. Angle u and 158°, have to add up to 180°. 180° - 158° = 22°, which is the angle measure of u. You're probably wondering how this will help us. The answer to that is it gives us the measurement of angle t, which is 158°. Now, we'll do the same thing we did with angle u, which was to make angle u add up with 158° to make 180°. We'll apply this to angle t and angle s. We already know that angle t is 158°, so angle s has to be 22° in order to add up to 180°. Therefore, your answer is 22° for angle s.

A bag contains 15 beads that are either red or yellow.
The probability of randomly removing a red bead is 20%.
What is the probability of randomly removing a yellow bead?
The probability of randomly removing a yellow bead is 0.8 or 80% if the bag contains 15 beads that are either red or yellow the probability of randomly removing a red bead is 20%.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have the probability P(R) of randomly removing a red bead is 20%.
Let's suppose the number of red beads is n(R)
[tex]\rm P(R) = 20\% \Rightarrow 0.20\\\\\rm \frac{n(R)}{15} = 0.20[/tex]
n(R) = 15×0.20
n(R) = 3
Number of yellow beads = 15 -3 = 12
The probability randomly removing a yellow bead:
[tex]=\rm \frac{12}{15}[/tex]
= 0.8 or 80%
Thus, the probability of randomly removing a yellow bead is 0.8 or 80% if the bag contains 15 beads that are either red or yellow the probability of randomly removing a red bead is 20%.

Write each quadratic equation in general form.
I need help direly
Answer:
9. 3x² +x -2y +5 = 0
10. 4x² +x -y +4 = 0
11. 9x² -6x -3y -12 = 0
Step-by-step explanation:
"General form" of a polynomial equation is ...
f(x, y) = 0
where the terms are arranged in lexicographical order and decreasing degree. That is, for terms of the same degree, x-terms are listed before y-terms, and xy terms are listed before y-only terms.
The leading coefficient can be positive or negative, your choice. (Positive is generally preferred.) For linear equations, "standard form" has the coefficients mutually prime. Making that happen for a general form polynomial would be your choice.
__
9.The highest-degree term is 3x². If we keep the leading coefficient positive, we can get general form by subtracting the expression on the left side of the equal sign.
3x² +x -2y +5 = 0
__
10.Subtracting the right side gives ...
4x² +x -y +4 = 0

Step-by-step explanation:
Why is it wrong to draw y=ln(2x-5) this way?
well because he did not do it
Notice how
2x-5 = 2x - 2*2.5 = 2(x-2.5)
This means we can replace x with x-2.5 in the second step, in the "wrong way" column.
So,
y = ln(2x)
y = ln( 2(x-2.5) )
y = ln( 2x - 2*2.5 )
y = ln( 2x - 5 )
In the second step, the x-2.5 tells the reader to shift the curve 2.5 units to the right. Therefore, the 1/2 = 0.5 would shift to 0.5+2.5 = 3 as indicated by the correct graph.
