(URGENT!!) Which graph models the function f(x) = -4(2)x? (2 points)

Mathematics
1 answer:
Usimov [2.4K]3 years ago
8 0

Answer:

2nd Graph

Step-by-step explanation:

Bases off the graphs, you gave me, I assume your the equation is

f(x) =  - 4(2) {}^{x}

The parent equation of this function is

f(x) = b {}^{x}

Let say x=0

Using the rules of exponets, the y value must be 1 so a critical point is

(0,1)

The function is multiplied by -4.

This means the function is stretched in the y direction by 4 and reflected over the x axis. So our new point will be

(0,-4).

The base 2 the function will get compressed by 1/2.

The best graph that represents this is the second graph

Nadya [2.5K]

Answer:

y=3\sqrt{7}\ units

Step-by-step explanation:

see the attached figure with letters to better understand the problem

we know that

In the right triangle ABD

tan(

In the right triangle BCD

tan(

remember that

m< BAD=m<CBD

therefore

tan(

equate the equations

y/9=7/y

y^{2}=63

y=3\sqrt{7}\ units

Rafael can choose plan a or Plan B for his long-distance charges. For each plan, cost (in dollars) depends on minutes used (Per
PilotLPTM [1.2K]

Answer:

a. Plan B; $4

b. 160 mins; Plan B

Step-by-step explanation:

a. Cost of Plan A for 80 minutes:

Find 80 on the x axis, and trave it up to to intercept the blue line (for Plan A). Check the y axis to see the value of y at this point. Thus:

f(80) = 8

This means Plan A will cost $8 for Rafael to 80 mins of long distance call per month.

Also, find the cost per month for 80 mins for Plan B. Use the same procedure as used in finding cost for plan A.

Plan B will cost $12.

Therefore, Plan B cost more.

Plan B cost $4 more than Plan A ($12 - $8 = $4)

b. Number of minutes that the two will cost the same is the number of minutes at the point where the two lines intercept = 160 minutes.

At 160 minutes, they both cost $16

The plan that will cost less if the time spent exceeds 160 minutes is Plan B.

Isabel drove 864 miles in 12 hours.<br> At the same rate, how many miles would she drive in 7 hours?
lyudmila [28]

Answer:

504 miles

Step-by-step explanation:

Make a proportion

\frac{864}{12} = \frac{x}{7}

7/12 is 0.5833, so multiply 864 by that to find the number of miles

864(0.5833) = 504
