Step-by-step explanation:
There are 360 seals on a beach. Of them 9/20 pups. The rest are adult seals. How many seal pups are on the beach? What percent of the seals on the beach are pups?
Answer:
First is irrational, second is rational, third is rational, fourth is irrational and fifth is irrational
Step-by-step explanation:
Rational Number is defined as the number which can be written in a ratio of two integers. An irrational number is a number which cannot be expressed in a ratio of two integers. In rational numbers, both numerator and denominator are whole numbers, where the denominator is not equal to zero.
btw please correct me if i'm wrong
Answer
because yes
Step-by-step explanation:
Answer:
y = - 2(x + 4)² + 6
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 ) = (- 4, 6 ) , thus
y = a(x - (- 4) )² + 6 , that is
y = a(x + 4)² + 6
To find a substitute (- 2, - 2) into the equation
- 2 = a(- 2 + 4)² + 6 ( subtract 6 from both sides )
- 8 = a(2)² = 4a ( divide both sides by 4 )
- 2 = a , thus
y = - 2(x + 4)² + 6 ← equation in vertex form
Answer:
14
Step-by-step explanation:
If you want to solve this question, you would need to know the sum of your number right now and after you add the blank number.
First one is: 8 + 4 + 11 + 13 = 36.
Second one: Sum = mean x [how many numbers there are], which means:
sum = 10 x 5 = 50.
Then, subtract the 36 from 50, and you get the answer: 14.
