Answer:

12/7=Big/Small

Step-by-step explanation:

A side in the smaller square is 7. A side in the bigger square is 12. That means the bigger side compared to the smaller side will be 12:7. That's the definition of a scale factor.

The functions f(x)=−34x+214 and g(x)=(12)x+1 are shown in the graph. What numbers are solutions to −34x+214=(12)x+1? Select each

DENIUS [597]

Answer:

$x=-1$

$x=1$

Step-by-step explanation:

we have

$f(x)=-\frac{3}{4}x+2\frac{1}{4}$ -----> equation A

$g(x)=\frac{1}{2}^{x} +1$ ----> equation B

To find the solutions for x of the system of equations

equate equation A and equation B

$-\frac{3}{4}x+2\frac{1}{4}=\frac{1}{2}^{x} +1$

The values of x of the intersection points are the solutions of the system

Using a graphing tool

see the attached figure

There are two intersection points

therefore

The solutions are

$x=-1$

$x=1$

Answer:

239 degrees.

Arc is circumference so length = r * 4.17133691221

Step-by-step explanation:

We eliminate RSQ in degrees = 90 + 31 = 121

So that;

RPQ = 360 -121 = 239 degrees

2pi radius (239/360) = r6.28318530718 (0.66388888888)

= r * 4.17133691221
