Answer:
- The function models exponential decay.
Step-by-step explanation:
Exponential function is:
- y = abˣ, where a- coefficient, b- base, x- exponent
When the coefficient is positive, the function is a growth if b > 1 and a decay if 0 < b < 1.
Given function has:
Since its coefficient is positive and base is between 0 and 1, it represents exponential decay.
Answer:
2
Step-by-step explanation:
Since ABC and A'B'C are similar triangles, the scale factor between their matching sides are equal to the overall scale factor. Thus, you would need to multiply AC by 2 to get the length of A'C'. 8/4 = 2.
Answer:
Probability= Number of possible outcome/Total
1/6 * 1/6= 1/36
Step-by-step explanation:
Answer:
y = 3x - 7
Step-by-step explanation:
The <em>point-slope formula</em> for a straight line is
y – y₁ = m(x – x₁)
x₁ = 4; y₁ = 5; m = 3 Substitute the values
y – 5 = 3(x - 4) Remove parentheses
y – 5 = 3x - 12 Add 5 to each side
y = 3x - 7
The graph is a straight line with a y-intercept at y = -7 and a slope = 12/4 = 3.
