Answer:
2.28 miles
Step-by-step explanation:
1 foot = 0.00019miles
12000 feet = x miles
Cross multiply
x = 12000 x 0.00019
x = 2.28 miles
3ax + b = c
subtract b from each side
3ax +b-b = c-b
3ax =c-b
divide each side by 3a
3ax/3a = (c-b)/3a
x = (c-b)/3a
Choice C
vertex= ?
axis line of symmetry equation?
Answer:
The vertex is at ( 3.5, -0.25)
and the axis of symmetry is x = 3.5.
Step-by-step explanation:
Convert to vertex form:
y = x^2 - 7x + 12
y = (x - 3.5)^2 - 3.5^2 + 12
y = (x - 3.5)^2 - 0.25
y = (x - 3.5)^2 - 0.25.
So the vertex is at ( 3.5, -0.25)
and
the axis of symmetry is x = 3.5.
The vertex of the parabola y = x² - 7x + 12 is at (3.5,-0.25) and the equation of the axis of symmetry is x = 3.5.
The given quadratic equation is y = x² - 7x + 12. To determine the vertex and the equation of the axis of symmetry, we need to first find the x-coordinate of the vertex, which is determined by the formula -b/2a. Here in our equation, a = 1 (coefficient of x²) and b = -7 (coefficient of x), so x = -(-7)/(2*1) = 3.5.
The x-coordinate of the vertex is thus 3.5. Now, to get the y-coordinate of the vertex, we substitute x = 3.5 into our equation, so y = (3.5)² - 7*(3.5) + 12 = -0.25. Therefore, the vertex of the parabola is at (3.5,-0.25). The line of symmetry of a parabola always passes through the vertex, so the equation of the axis of symmetry is x = 3.5.

Correct option d)0.61
Step-by-step explanation:
Here we have a number line from 0 to 1 . With every point at a equal distance of 0.10 from each other . Let's first mark the decimal 0.74 in number line . Now, Lets check one by one that which decimal is less than 0.74 . Remember , decimal will be less than 0.74 if point lies to the left side of 0.74.
a)0.95:
Decimal 0.95 lies to right side of 0.74 , So this decimal is not smaller than 0.74
b)0.88:
Decimal 0.88 lies to right side of 0.74 , So this decimal is not smaller than 0.74
c)0.79:
Decimal 0.79 lies to right side of 0.74 , So this decimal is not smaller than 0.74
d)0.61:
Decimal 0.61 lies to left side of 0.74 , So this decimal is smaller than 0.74
