Answer:
The table with the y values of 1, 4, 16, 64, and 256 represent an exponential function.
This table shows an exponential function. This is easily seen by looking at the values of y. As you go down the rows of the y-values, you notice that the numbers are being multiplied by the value of 4.
1 x 4 = 16
16 x 4 = 64
64 x 4 = 256.

Where pi is defined as the ratio of a circle’s circumference
divided by the diameter of the its circle. Pi has a value which is 3.1416. This
pi is a constant value expressed by the quotient of its circumference over the diameter.
What type of number best describes the diameter is the pi. Hence, if we
describe the diameter, diameter is the quotient of pi over the circumference of
a circle by itself. It can’t change in value since for every solution and
quotient of a circle each calculation gets 3.14 more or less. </span>
Answer:
Step-by-step explanation:
Each equation is in vertex form, so you can easily determine the number of real roots. The leading coefficient tells you whether the parabola opens upward (positive) or downward (negative).
y = a(x -h)^2 +k
has leading coefficient "a" and vertex (h, k).
__
<u>f(x) = 1/3(x +5)^2 +7</u>
vertex: (-5, 7), opens downward
The vertex is above the x-axis, so there are two real roots.
__
<u>f(x) = -5(x -3)^2</u>
vertex: (3, 0), opens downward
The vertex is on the x-axis, so there is one real root.
Answer:
A.45
Step-by-step explanation:
Since it is an expression and not an equation, you would just have to distribute the -3 to the two inside the parentheses.
The answer is -9 + 30x
