Answer:
Step-by-step explanation:
Perimeter of square park = 2000 m
4*side = 2000
side = 2000 ÷ 4
side = 500 m
Area of square park = side * side
= 500 * 500
= 250000 m²
Answer:
-15
Step-by-step explanation:
(5*a*b*c) / (b) => (5*3*-4*-1) / (-4)
=> (60) / (-4)
=> -15

Answer:
Both are correct.
A) A decimal fraction
B) A common fraction
Step-by-step explanation:
<u>1 step.</u> Write down 0.4 divided by 1:
<u>2 step.</u> Multiply both top and bottom by 10 (because there are 1 digit after the decimal point):
This fraction is called a decimal fraction.
<u>3 step.</u> Simplify the decimal fraction:
This fraction is called a common fraction.
Answer:
The equation in vertex form is:
Step-by-step explanation:
Recall that the formula of a parabola with vertex at is given by the equation in vertex form:
where the parameter can be specified by an extra information on any other point apart from the vertex, that parabola goes through.
In our case, since the vertex must be the point (2, 1), the vertex form of the parabola becomes:
we have the information on the extra point (0, 5) where the parabola crosses the y-axis. Then, we use it to find the missing parameter :
The, the final form of the parabola's equation in vertex form is:
