Lubov Fominskaja [6]

Answer:

$y=4(3)^x$

Step-by-step explanation:

From the table given in the question,

x y Difference Ratio

1 12 - -

2 36 36-12 = 24 $\frac{36}{12}=3$

3 108 108-36 = 72 $\frac{108}{36}=3$

4 324 324-108 = 216 $\frac{324}{108}=3$

5 972 972-324 = 648 $\frac{648}{216}=3$

There is a common ratio of 3 in each successive term.

Therefore, data given in the table will represent an exponential function.

$y=a(b)^x$

For a point $(1, 12),$

$12=a(b)^1$

$ab=12$ ------(1)

For another point of the table $(2,36)$ ,

$36=a(b)^2$

$ab^2=36$ --------(2)

Equation (2) divided by equation (1)

$\frac{ab^2}{ab}=\frac{36}{12}$

$b=3$

From equation (1),

$3a=12$

$a=4$

Therefore, exponential function will be,

$y=4(3)^x$

Find the missing length indicated. A) 48 B) 36 C) 100 D) 64

alexandr402 [8]

Answer:

Option D) 64

Step-by-step explanation:

see the attached figure with letters to better understand the problem

In the right triangle BCD find BC

Applying the Pythagoras Theorem

$BC^{2}=48^{2}+36^{2}\\BC^{2}=3,600\\BC=60\ units$

In the right triangle ABC

$cos(C)=BC/AC$

substitute the values

$cos(C)=60/(x+36)$ -------> equation A

In the right triangle BDC

$cos(C)=CD/BC$

substitute the values

$cos(C)=36/60$ -------> equation B

equate equation A and equation B

$60/(x+36)=36/60\\ \\(x+36)*36=60*60\\ \\36x+1,296=3,600\\ \\36x=3,600-1,296\\ \\36x=2,304\\ \\x=64\ units$

Write an equation of the line graphed in slope-intercept form:

masya89 [10]

Answer:

-2.5x+2

I hope this is good enough:

y-intercept is at positive 2 so you would have +2

it has a negative slope because it is going downwards

on the graphing calculator I used 2 wasn't big enough to make the x intercept and 3 was to big so I went in the middle and it looked correct.
