malfutka [58]
3 3/6 is the same as 3 1/2, so 23 take 3 is 20. 20 take 1/2 is 19 1/2.

What sine function represents an amplitude of 4, a period of pi over 2, no horizontal shift, and a vertical shift of −3?
mixer [17]

Answer:

f(x) = 4sin(\frac{\pi}{2}x) - 3, the third one

Step-by-step explanation:

Explaining the sine function:

The sine function is defined by:

S = Asin(p(x - x_{0})) + V

In which A is the amplitude, p = \frac{2\pi}{N} is the period, x_{0} is the horizontal shift and V is the vertical shift.

So, in your problem:

The amplitude is 4, so A = 4.

The period is \frac{\pi}{2}, so p = \frac{\pi}{2}.

There is no horizontal shift, so x_{0} = 0.

The vertical shift is −3, so V = -3.

The sine function that represents these following conditions is

f(x) = 4sin(\frac{\pi}{2}x) - 3, the third one

A paperweight is shaped like a triangular pyramid. The base is an equilateral triangle. Find the surface area of the paperweight
stich3 [128]

Answer:

The surface area of the paperweight is SA=8.3\ in^2

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to the area of its triangular base plus the area of its three triangular lateral faces

so

<em>Find the area of its triangular base</em>

SA=\frac{1}{2}(2)(1.7)

SA=1.7\ in^2

<em>Find the area of its three triangular lateral faces</em>

SA=3[\frac{1}{2}(2)(2.2)]

SA=6.6\ in^2

Adds the areas

SA=1.7+6.6

SA=8.3\ in^2

Does the table represent a exponential function x 1 2 3 4 y -1 -8 -27 -64
Setler79 [48]

Answer:

No, the given function is not an exponential function.

Step-by-step explanation:

The exponential function is defined as

f(x)=ab^x                   .... (1)

Where a is initial value and b is growth factor.

From the given table it is noticed that the value of y decreased as the value of x increased by 1. The function is in the form of

f(x)=-x^3                  .... (2)

f(1)=-(1)^3=-1

f(2)=-(2)^3=-8

f(3)=-(3)^3=-27

f(4)=-(4)^3=-64

The function (1) and (2) are not the same type of function.

The table represents the polynomial.

Therefore the required answer is no. The given function is not an exponential function.
