Answer:
The possible values of x are ±8 sqrt(2)
Step-by-step explanation:
To find the value of x, we find the geometric mean
sqrt(32*4 )= sqrt(128) = ±8 sqrt(2)
The possible values of x are ±8 sqrt(2)
Answer:

Step-by-step explanation:
→ State the gradient formula
( y₂ - y₁ ) ÷ ( x₂ - x₁ )
→ Find x₁ , x₂ , y₁ and y₂
x₁ = 4 , x₂ = 12 , y₁ = 9 and y₂ = 20
→ Substitute in the values

→ Simplify

Answer: c) choosing a consonant from the set {b, c, d, e, f}
Step-by-step explanation:
Since all of the choice sets have 5 values each, a 0.8 chance = 80% =
.
So find the set with 4 values that meet the criteria.
A: 5/5 = 1 = 100%
B: 1/5 = 0.2 = 20%
C: 4/5 = 0.8 = 80%
D: 0/5 = 0 = 0%
Answer:
D. all real numbers
Step-by-step explanation:
The domain is all the x's on a graph or that are permitted in an equation (if you have an equation instead of a graph)
If there is nothing on the graph to indicate the graph is a segment (endpoints that are either closed or open) or has other holes in it (literally a point on the line that is open) then the domain for a linear function (a line) is always all real numbers. The same is true for all of the above for the range as well, except the range is all the y's
