Answer:
She saw 60 dogs over the two days.
Step-by-step explanation:
Consider the provided information.
It is given that Maria saw dogs in the park on Saturday.
can be written as 2×10 = 20
That means she saw 20 dogs on Saturday.
She saw twice as many dogs on Sunday as she saw on Saturday.
She saw 20 dogs on Saturday the twice of this is:
Sunday = 20×2 = 40 dogs
Total number of dogs she saw on Saturday and Sunday = 40 + 20 = 60
Hence, she saw 60 dogs over the two days.
Answer:
Step-by-step explanation:
Notice that the focus is a points on the vertical axis, that means the parabolla opens vertically, and has the form
Because the parameter is positive and equal to 0.75. Additionally, the vertex is at the origin, that's why the equation is this simple.
Replacing the parameter value, we have
Therefore, the equation of a parabolla with vertex at the origin and focus at (0, 0.75) is .
