Answer:

x=20. y=15

Step-by-step explanation:

in similar triangles the sides are all in proportion. this means:

$\frac{25}{5} = \frac{x}{4} = \frac{y}{3}$

$\frac{25}{5} = 5$

so:

$\frac{x}{4} = 5$

x=5×4

x=20

and...

$\frac{y}{3} = 5$

y=3×5

y=15

Which equation represents an exponential function that passes through the point (2, 36)?

zimovet [89]

Y= aˣ . This is the exponential function:

If x = 2, then y = 36

36 = a² → a = 6

Then the equation becomes: y = 6ˣ

Find an approximate equation y=ab^x with the coordinates (0, 4) (3, 95)

bogdanovich [222]

We have $y=ab^{x}$

Plug in $(0, 4)$ :
$4=ab^{0}$ ⇒ $4=a$
So we now have $a$

Plug in $(3, 95)$ :
$95=4b^{3}$
⇒ $b^{3}=\frac{95}{4}$
⇒ $b=\sqrt[3]{\frac{95}{4}}$
which is approximately 2.874

So we get
$y=4(\sqrt[3]{\frac{95}{4}})^{x}$
or, in decimal form,
$y=4*2.874^{x}$
