An irrational number is a number that cannot be expressed in a fraction form while a rational number can.
an example of an irrational numbers are repeating numbers such as 0.77777... and examples of rational numbers are decimals such as 0.20, whole numbers such as 5, and fractions like 2/3
hope this helps a bit.
Answer:
C
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (5, 2), thus
y = a(x - 5)² + 2
To find a substitute (4, - 3) into the equation
- 3 = a + 2 ⇒ a = - 3 - 2 = - 5
y = - 5(x - 5)² + 2 ← in vertex form
Expand (x - 5)² and distribute by - 5
y = - 5(x² - 10x + 25) + 2
= - 5x² + 50x - 125 + 2
= - 5x² + 50x - 123 ← in standard form

Answer:
<h2><em><u>4</u></em></h2>
Step-by-step explanation:
![\sqrt[3]{64}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B64%7D%20)
![= \sqrt[3]{4 \times 4 \times 4}](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%5B3%5D%7B4%20%5Ctimes%204%20%5Ctimes%204%7D%20)
= <em><u>4</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
50 boys 35 girls 4.40 times 5 is 22+14=36
so all your doing here is 35 times 0.4 because their are 35 girls and you multiple that by 0.4
same thing for the guys anyway answer is 36
