Answer x= 18 y=-39
Step-by-step explanation:
Responder:
42 bombones
Explicación paso a paso:
Dado que :
Número de bombones = 60
Cantidad consumida por Eba = 1/5 * 60 = 12
Cantidad comida por Ana = 1/2 * 60 = 30
Cantidad de chocolate que comieron Eba y Ana:
(12 + 30) = 42
De ahí que Ana y Eba se comieran 42 bombones
Answer:
The cosine function that is represented in the graph is:
Option B. f(x)=cos (x-pi/4)-1
Step-by-step explanation:
The parent function is cos x.
cos x at x=0 has the maximum value 1.
The graph is shifted to the right (x-pi/4) with a maximum value 0 at x=pi/4, then the graph is shifted downward 1 unit.
Then f(x)=cos (x-pi/4)-1
Please, see the attached graph:
The blue line is the parent function y=cos x
The red line is the graph given
Answer:
12
Step-by-step explanation:
Make 6 a reciprocal which would be 1/6 then change the division sign to multiplication so 1/6 x 1/2 will be 12
For t²+6t-20=0 (to find the vertex, or rather the x intercepts), we can add 20 to both sides to get t²+6t=20. Since 6/2=3, we can square 3 to get 9. Adding 9 to both sides, we get t²+6t+9=20+9=29=(t+3)². Finding the square root of both sides, we get t+3=+-√(29). Subtracting 3 from both sides, we get t=+-√(29)-3=either √(29)-3 or -√(29)-3. We have -√(29)-3 due to that t can either be negative or positive. Finding the average of the two numbers, we have
(√(29)-3)+(-√(29)-3./2=-6/2=-3, which is our t value of our vertex and since it's t² and based around t, that is our axis of symmetry. To find the y value of the vertex, we simply plug -3 in for t to get 9+(6*-3)-20=9-18-20=-29, making our vertex (-3, -29)
