68.5. You take 62 and divide it by the percentage as a decimal, .905. 62 / .905 = 68.5.
Answer: The vertex of the parabola (quadratic function) is (-2,-4)
Fourth option: (-2,-4)
Solution:
y=x^2+4x
y=ax^2+bx+c; a=1, b=4, c=0
Vertex: V=(h,k)
h=-b/(2a)
h=-4/(2(1))
h=-4/2
h=-2
y=x^2+4x
k=y=h^2+4h
k=(-2)^2+4(-2)
k=4-8
k=-4
Vertex: V=(h,k)
Vertex: V=( -2, -4)
Roots of the equation 3x² -3x-6=0 are -1 and 2,
all choices are given wrong
3*2²-3*2-6=0
12-6-6=0
0=0, which is true , so root is 2
3*20²-3*20-6=0
600-60-6=0
534=0 which is wrong, so root is 2, but not 20
Answer:
x = 7.5
Step-by-step explanation:
Since the midsegment and the third segment of the triangle are parallel to each other, therefore,
Cross multiply
Subtract 24 from each side
54 - 24 = 4x
30 = 4x
Divide both sides by 4
30/4 = x
7.5 = x
x = 7.5
Answer:
part a is 7.92
Step-by-step explanation:
3 x 2 is 6 and 2/3 as a % is .66 x 2 is 132%
so taking 6 and 132% which is 1.32 and multiply them together to get 7.92
