Answer:
y = 
x² - 7
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (0, - 7), thus
y = a(x - 0)² - 7
To find a substitute (4, - 3) into the equation
- 3 = a(4 - 0)² - 7, that is
- 3 = 16a - 7 ( add 7 to both sides )
4 = 16a ( divide both sides by 16 )
a = , thus
y = x² - 7
79, 79, 91, 91, 91, 91, 98, 98, 118, 130, what is the mean median and mode?
Rus_ich [418]
To get the mean you add the numbers and divide by how many numbers there are and then you would get: 784 divided by 10 which would be 78.4 for the mean

A regular quadrilateral has 4 congruent sides and 4 angles
- False. A regular quadrilateral has 4 angles- this bit is correct. But the bit about 4 congruent sides is not true, they could be different
Answer:
0.75
Step-by-step explanation:
Percent means per 100, which indicates we have to go to the hundreth's decimal place. As a fraction, it would be represented as 75/100.
