Answer:
a) 187.5 b) Domain c ∈ [0,187.5] c) Range ∈ [0,15]
Step-by-step explanation:
a) In this function, d stands for dollars and c stands for cookies. Ashley left $15 to pay supplies for making new cookies. The more cookies they made the less money it is left. For instance, If someone bakes 1 cookie using that money:
d=15-0.08c d=15-0.08(1) d=14.92 Then $14.92 is left after baking 1 cookie. And so on.
To find the zero of this function, let's turn this into an equation.
So according to this function, with 15 dollars at least 187 cookies can be made.
b) The function d=15-0.08c if it was defined for the Real Set, any value would be valid within the Real Set. But c, is for cookies. Then the set is
Domain c ∈ [0,187.5]
c) The Range
The Range is the subset of all values between $15 and 0$, since after the money is over they can no longer bake cookies. And there's $-1 dollar note.
So the Range is d ∈ [0,15]
3(X-2) = 22- x
Expanding the bracket by multiplying the 3 outside the bracket with x and 2, it becomes 3x- 6= 22-×
Take like terms of X
3x+x = 22+6
4× =28
Divide both sides by 4
X= 7
Answer:
9cm
Explicación:
El teorema de pitagoras nos dice que la hipotenusa al cuadrado es igual a la suma de los catetos al cuadrado:
Donde c es la hipotenusa y a y b son los catetos.
Por lo cual, podemos reemplazar c por 15cm y a por 12cm :
Finalmente , debemos resolver la ecuación para b, así que b es igual a :
Por lo tanto, la longitud del otro cateto es 9 cm
Answer:
5 hours
Step-by-step explanation:
We know that Joey spent a total of $325. He first paid the fee of $150. Let's subtract $150 from $325.
$325 - $150 = $175
Now, we know that it costs $35 per hour to rent the car. So, we divide $175 by $35 to find out how many hours Joey rented the car for.
$175 ÷ $35 = 5 hours
Think about it this way: which numbers are perfect squares? The square root of 4 is two, the square root of 49 is 7, and the square root of 64 is 8. That only leaves B.
I hope this helps. Let me know if you need a further explanation.
