An irrational number is a number that can be written as the square root of a non-square number, and numbers that can't be written as the quotient of two integers.
For the given ones we have:
a) 3.14 = 314/100 this is a rational number.
b) √5, 5 is not a perfect square, so √5 is an irrational number.
c) 0.3333 = 3333/10,000 this is a rational number.
d) √-4 The square root of a negative number is a complex number.
e) 1/9 this is a rational number.

Harshdeep was playing basketball with his friends with seconds left before the game ended he attempted a 3 point shot the following equation models the path of the basketball y=-x^2+4x+5 where x is the elapsed time in seconds
Answer:
After two seconds, the ball reached 9 units up.Step-by-step explanation:
The given function is
[tex]y=-x^{2} +4x+5[/tex]
The given function models the path of the ball.
The maxium height the ball reached is given by the vertex of this function, which has coordinates [tex]V(h,k)[/tex], where [tex]h=-\frac{b}{2a}[/tex] and [tex]k=f(h)[/tex].
From the equation, we know that [tex]a=-1[/tex], [tex]b=4[/tex] and [tex]c=5[/tex]. Replacing these values, we have
[tex]h=-\frac{4}{2(-1)}=2[/tex]
[tex]k=f(2)=-(2)^{2} +4(2)+5=-4+8+5=9[/tex]
Where [tex]k[/tex] determines the height and [tex]h[/tex] the time when the maximum height was reached by the ball.
The maximum height is 9 units.
Therefore, after two seconds, the ball reached 9 units up.
A variable is a quantity that can change; the word also refers to the letter or symbol that represents this quantity. In a proportional relationship, one variable is the independent variable, and one is the dependent variable. They are often called "x" and "y," but any letters can be used. The value of the dependent variable depends on the value of the independent variable. In the relationship between number of scoops of ice cream and total price, we can call number of scoops "x" and total price "y." Y is dependent because its value depends on x, the number of scoops you purchase. Ursula makes $5 for every 1 dog she walks. In the relationship between dollars earned and dogs walked, ________ is the dependent variable, which is often called ________.
Answer:
Dollars earned is the dependent variable, which is often called outcome variable (x).
Step-by-step explanation:
The value of the dependent variable depends on the value of the independent variable.
y (dollars earned) is dependent because its value depends on x, the number of dogs walked.
In the relationship between dollars earned and dogs walked, dollars earned is the dependent variable, which is often called outcome variable (x).

The Anderson family has 3 kids 3 boys and 0 girls suppose that for each birth the probability of a boy birthday is 1/2 and the probability of a girl birth is also 1/2 what is the fractional probility of having 3 boys and 0 girls ina family first 3 births
Answer:
Fractional probability of having 3 boys and 0 girls in a family for first 3 births is [tex]\frac{1}{8}[/tex].
Step-by-step explanation:
Let A be the event of birth of a boy.
Let B be the event of birth of a girl.
Probability of birth of a boy, P(A) [tex]= \frac{1}{2}[/tex]
Probability of birth of a girl, P(B) [tex]= \frac{1}{2}[/tex]
We have to find the probability of birth of 3 boys i.e. event A occurring 3 times in a succession. It is independent events i.e. do not have any dependency on occurrence of any event.
So, Required probability can be calculated just by multiplying P(A) for 3 times.
i.e.
[tex]P(E) = P(A) \times P(A) \times P(A)\\\Rightarrow \dfrac{1}{2} \times \dfrac{1}{2} \times \dfrac{1}{2}\\\Rightarrow \dfrac{1}{8}[/tex]
So, the probability of having 3 boys and 0 girls in the family is [tex]\frac{1}{8}[/tex].
You are building a sand castle and want to use a bucket that holds a volume of 885 in.cubed and has height 11.7 in. What is the radius of the bucket? Use 3.14 for π.
Answer:
[tex]4.91 in[/tex]
Step-by-step explanation:
a bucket has the form of a cylinder, which has the following formula for its volume:
[tex]V=\pi r^2h[/tex]
where r is the radius and h is the height.
Since we need to find the radius, we solve for r:
[tex]r^2=\frac{V}{\pi h}\\ \\r=\sqrt{\frac{V}{\pi h} }[/tex]
and since we know according to the problem that:
[tex]V=885in^3[/tex]
and
[tex]h=11.7in[/tex]
substituing these values:
[tex]r=\sqrt{\frac{885in^3}{(3.14)(11.7in)}}\\ \\r=\sqrt{\frac{885in^3}{36.738in}}\\\\r=\sqrt{24.0895in^2}\\\\r=4.908in[/tex]
the radius is: [tex]4.908in[/tex] which can be rounded to [tex]4.91 in[/tex]

Determine whether the linear transformation is invertible. If it is, find its inverse. (If an answer does not exist, enter DNE.) T(x, y) = (-x + y, -x - y)
Answer:
[tex]((-\frac{1}{2}(x+y), -\frac{1}{2} (x-y) )[/tex]
Step-by-step explanation:
T(x , y) = (-x -y, -x +y)
T(1, 0) = (-1, -1) = -1(1 , 0) -1(0 , 1)
T(0, 1) = (-1, 1) = -1(1 , 0) +1(0 , 1)
Therefore,
[tex]T = \left[\begin{array}{ccc}-1&-1\\-1&1\end{array}\right][/tex]
|T| = [-1 -1] = -2
T is invertible
[tex]T^-^1 = -\frac{1}{2} \left[\begin{array}{ccc}1&+1\\+1&-1\end{array}\right] \\\\=\left[\begin{array}{ccc}-1/2&-1/2\\-1/2&1/2\end{array}\right][/tex]
Therefore,
[tex]T^-^1(x,y)=(-\frac{1}{2}x -\frac{1}{2} y,-\frac{1}{2} x+\frac{1}{2} y)[/tex]
[tex]((-\frac{1}{2}(x+y), -\frac{1}{2} (x-y) )[/tex]

Step-by-step explanation:
yes coz in a right angled triangle all the sides are never equal
Answer:
No, they do not make a right triangle.
Step-by-step explanation:
Use the Pythagorean Theorem to see if the sides form a right triangle.
[tex]a^2+b^2=c^2[/tex]
'20' will be 'c'. It is the largest number in the sides given.
'8' will be 'a' and 17 will be 'b'.
[tex]8^2+17^2=20^2\\\rightarrow 8^2=64\\\rightarrow 17^2 = 289\\\rightarrow 20^2=400\\64+289=400\\\boxed{353\neq 400}[/tex]
The sides do not make a right triangle. They do not satisfy the theorem.

[tex]\frac{3^{2} }{6^{2} }[/tex]÷[tex]\frac{2^{2} }{2^{2} }[/tex] AYUDAAAA !!!
Answer:
1/4
Step-by-step explanation:
Simplify the following:
(3^2/6^2)/(2^2/2^2)
Multiply the numerator by the reciprocal of the denominator, (3^2/6^2)/(2^2/2^2) = 3^2/6^2×2^2/2^2:
(3^2×2^2)/(6^2×2^2)
(3^2×2^2)/(6^2×2^2) = 2^2/2^2×3^2/6^2 = 3^2/6^2:
3^2/6^2
6^2 = 36:
3^2/36
3^2 = 9:

Triangle L J K is shown. Angle J L K is a right angle. The length of the hypotenuse is 15 inches and the length of the side adjacent to the right angle is 10 inches. The angle between the 2 sides is x.
Which equation can be used to find the measure of angle LJK?
Answer:
The answer is C on Edge 2020
Step-by-step explanation:
The value of x will be 48.19°. Then the measure of angle LJK will be 41.81°.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
Triangle LJK is shown.
Angle ∠JLK is a right angle.
The length of the hypotenuse is 15 inches, and the length of the side adjacent to the right angle is 10 inches.
The angle between the 2 sides is x.
Then the measure of the angle x will be given by cosine of x.
cos x = 10 / 15
cos x = 0.667
x = 48.19°
The value of x will be 48.19°.
We know that the sum of the angle of triangle is 180°.
Then the measure of angle LJK will be
∠LJK + 90° + 48.19° = 180°
∠LJK = 41.81°
