The graph of a quadratic function touches, but does not cross, the x-axis at x = 4. Which function represents this situation?

2 answers:

5 0

When a zero of a function does not cross the x-axis but touches it, this means that the zero is a "double root". It has two of the same factor (x - 4)^2 and two of the same zeros, x = 4 and x = 4
f(x) = x^2 - 8x + 16 would be the function with a double root at 4

What is -11 + 3(b + 5) = 7

IRISSAK [1]

Answer:

b=1

Step-by-step explanation:

$\sf -11 + 3(b + 5) = 7$

First, let's regroup, terms,

$\sf 3(b+5)-11=7$

Add 11 to both sides,

$\sf 3(b+5)=7+11$

Simplify, 7+11 = 18,

$\sf 3(b+5)=18$

Now, divide both sides by 3,

$\sf b+5=\frac{18}{3}$

Simplify, 18/3 = 6,

$\sf b+5=6$

Subtract 5 from both sides,

$\sf b=6-5$

$\sf b=1$

Hope it helps! :)

Which experimental design compares two groups (randomly formed) on the same task, such as movement speed

anygoal [31]

Between-group design compares two groups (randomly formed) on the same task, such as movement speed.

Given things that there are two groups that are randomly formed for the same task.

A between-group design in experimental design is an experiment in which two or more groups of individuals are assessed simultaneously by separate testing factors. This design is typically used instead of, or in conjunction with, the within-subject design, which applies identical modifications of circumstances to each participant in order to monitor the reactions.
