What is the equation of the parabola ?
Answer:
D. y = 1/12x² + 2Step-by-step explanation:
As per graph we observe:
The y-intercept is 2The coefficient is positive as the graph opens upAccording to the observations, the equation is:
y = 1/12x² + 2Correct choice is D
b is y intercept,a is coefficient
Here a is 1/12 as every option contains this factor so don't calculate.
As parabola is opening upwards a is positive
and
y intercept is 2
So the equation is
y=1/12x²+2Find the value of f(-4).

Answer:
i got this questions, i put A,B, and D
Step-by-step explanation:
the three of them are similar in size if that makes sense, im not 100% sure but i got a harder question after it so im pretty sure its right.
Using it's concept, it is found that the box-and-whisker plots A, B and D have the same interquartile range of 4.
What does a box-and-whisker plot shows?It shows three things:
The left bound is the first quartile.The middle bound is the median.The right bound is the third quartile.The interquartile range is the difference of the third quartile and the first quartile, hence it is the length of the box-and-whisker plot. From this, plots A, B and D have the same interquartile range of 4.

The value of a in y³ - 5y² + 72y - 68 = 0 is -5
Quadratic equation
A quadratic equation is in the form:
ax² + bx + c = 0
where a, b, c are constants integers.
Given the roots of the equation as 1 and 2 - 8i, hence the third root is 2 + 8i. Complex roots are in conjugate pairs, hence:
y = 1 or y = 2 - 8i or y = 2 + 8i
(y - 1) = 0; y - 2 + 8i = 0 and y - 2 - 8i = 0
(y - 1)(y - 2 + 8i)(y - 2-8i) = 0
y³ - 5y² + 72y - 68 = 0
The value of a in y³ - 5y² + 72y - 68 = 0 is -5

Three bag of sweet weight 6 3/4 kg two of them have the same weight and the third bag is heavier than each of the bag of equal weight by 1 1/5 find weight of each bag
Answer:
lighter bag weighs 1 [tex]\frac{83}{100}[/tex]
heavier bag weighs 3 [tex]\frac{3}{100}[/tex]
Step-by-step explanation:
let x = weight of lighter bag
let x+6/5 = weight of heavier bag
2x + x+6/5 = 6 3/4
3x + 6/5 = 27/4
3x = 27/4 - 6/5
3x = 111/20
x = 111/20 ÷ 3
x = 1 83/100
x+ 6/5 = 3 3/100

Answer:
23 miles.
Step-by-step explanation:
Using the given, 4 and 5.75, we can create an equation.
To create a valid equation, we must multiply 4 and 5.75 to find the total distance.
4(5.75) = T
T = the total distance of the bike ride.
Solve:
4(5.75) = 23.
Your solution is 23 miles, the total distance of the bike ride.
