Answer:
The vertex is (-1, 3)
Step-by-step explanation:
The form this is in is called vertex form. We can express the equation using its base form.
y = a(x - h)^2 + k
Now we can identify the vertex as (h, k). By looking at the equation, we can see h is equal to -1 and k is equal to 3.
Answer:
3(1−10x)43(1-10x)4
Step-by-step explanation:
34−4x+12x−212x34-4x+12x-212x
Simplify each term.
Combine 1212 and xx.
34−4x+x2−212x34-4x+x2-212x
Multiply the numerator by the reciprocal of the denominator.
34−4x+x2−(2(2x))34-4x+x2-(2(2x))
Multiply 22 by 22.
34−4x+x2−(4x)34-4x+x2-(4x)
Multiply 44 by −1-1.
34−4x+x2−4x34-4x+x2-4x
Find the common denominator.
Write −4x-4x as a fraction with denominator 11.
34+−4x1+x2−4x34+-4x1+x2-4x
Multiply −4x1-4x1 by 4444.
34+−4x1⋅44+x2−4x34+-4x1⋅44+x2-4x
Multiply −4x1-4x1 and 4444.
34+
The answer is true. An exponent is how many times you multiply (10) by (10).
10^1=10
10^2=10*10=100
and so on
Answer:
120 000 m^2
Step-by-step explanation:
I ASSUME you're being asked to convert from km^2 to m^2.
For this you need to identify the conversion rate, which is 1 000 000 m^2 / 1 km ^2. Multiply by the thing you're converting from and cancel the units.
(1 000 000 m^2 / 1 km ^2) x 0,12 km^2 = 120 000 m^2 (the km^2 cancels out, leaving you only with your target unit of m^2)
