Chad jogs 8 4/5 miles per hour.
Answer:
A
Step-by-step explanation:
Quadratic function has a degree of 2, that means the highest power of x is 2.
They have a shape "U" and are known as "parabolas".
They can have 0, 1, or 2 x-intercepts depending on the type of roots (solutions) the equation has.
Imagine a U shaped curve (quadratic) that doesn't intersect x-axis at all. It will have no real solutions.
Now, imagine a U shaped curve (quadratic) that touches the x-axis and goes up or down. That one has two same real solutions.
Third, imagine a U shaped curve (quadratic) that intersects the x-axis TWICE and goes up or down. That one has 2 distinct real solutions.
Hence, the maximum number of x-intercepts any quadratic function can have is "2".
Correct answer is A
She walks 6/5 of a mile in 1 hour
So, she walks 1.2 miles per hour

Scientific notation is a special way we choose for writing numbers. So the numers are written in scientific notation. In this way, we have a quotient of two numbers written in scientific notation. To solve this problem, we have:
The division has been performed using the rules for operation with exponentiation.
If diagonals of a parallelogram are perpendicular to each other, this is a rhombus. A rhombus has all sides equal.
In the current scenario, the shorter rhombus is 20 cm long and has a perimeter of 80 cm
Side of rhombus = 80/4 = 20 cm
A quarter of rhombus is right angled triangle with hypotenuse being side of rhombus.
Half length of long diagonal = sqrt (20^2-10^2) = 17.32 cm
Length of longer rhombus = 17.32*2 = 34.64 cm
