Write the equation in exponential form using the two points (0,1) and (1,3)

MakcuM [25]

Answer:

$y=3^x$

Step-by-step explanation:

The equation of the function in exponential form is

$y=a\cdot b^x$

The function is determined using points (0,1) and (1,3), so their coordinates satisfy the eduation. Substitute them:

$1=a\cdot b^0\Rightarrow a=1\ \ [b^0=1]\\ \\3=a\cdot b^1\Rightarrow 1\cdot b=3,\ b=3$

Thus, the equation of the function is

$y=3^x$

There is no solution to the equation cscx=0. True or False

Svetradugi [14.3K]

Answer:

True

Step-by-step explanation:

First, we need to recognize that

$csc(x)=\frac{1}{sin(x)}$

Now, we can try to solve

$\frac{1}{sin(x)} =0$

Multiply each side by $sin(x)$

$1=0*sin(x)\\\\1=0$

As we end up with an answer that cannot be true, we know that there is no solution.

Another method to solve this would be graphing the function $y=csc(x)$

When graphed, it can be seen that there is an asymptote at x=0 meaning that there is no value for x=0.

Which figure could be the result of dilating the trapezoid with a scale factor between 0 and 1? On a coordinate plane, a trapezo

Lelechka [254]

Answer:

On a coordinate plane, a trapezoid has points (0, 0), (0.5, 2), (1, 2), (1.5, 0).

Step-by-step explanation:

The given trapezoid has vertices at

(0, 0), (1, 4), (2, 4), (3, 0).

We want to choose from the given options the trapezoid with a scale factor between 0 and 1.

If a scale factor of a dilation is between 0 and 1, the size of the image trapezoid will be smaller than the preimage.

When we analyze the coordinates carefully, the answer is, a trapezoid has points (0, 0), (0.5, 2), (1, 2), (1.5, 0).

The reason is that, when we multiply the coordinates of (0, 0), (1, 4), (2, 4), (3, 0) by 0.5, we obtain (0, 0), (0.5, 2), (1, 2), (1.5, 0).

Hence the scale factor is 0.5 and this is between 0 and 1.
