Answers

Answer 1

Answer:

Answer:

Graph D

Step-by-step explanation:

$f(x)= 2^x$

Given f(x) is a exponential function

The graph (a) is a graph of an absolute function because we have V shaped graph

The graph (b) is the graph of a line so it is a graph of a linear function

The graph (c) is a U shaped graph. U shaped graph is a graph of a quadratic function.

The graph (d) is a curve shaped graph. It is a graph of an exponential function.

Answer 2

Answer:

Option D is the correct answer

i need this quick!!! please hurry!! Solve the following proportion for X. X over 5 = 17 over 3 Round your answer to the nearest tenth.

Answers

Answer:

$\huge\boxed{x = 28.3}$

Step-by-step explanation:

=> $(x)/(5) = (17)/(3)$

Cross Multiplying

=> x * 3 = 5 * 17

=> 3x = 85

Dividing both sides by 3

=> x = 85/3

=> x = 28.3 (To nearest tenth)

Answer:

$\Huge \boxed{x=28.3}$

Step-by-step explanation:

The proportion is given,

$\displaystyle (x)/(5) =(17)/(3)$

We need the x variable isolated on one side, so we can find the value of x that makes the proportion true.

Multiply both sides of the equation by 5.

$\displaystyle (x)/(5) * (5)=(17)/(3) * (5)$

Simplify the equation.

$\displaystyle x=(85)/(3)$

$x=28.33333333...$

The value of x that makes the proportion true is 28.3 (rounded to nearest tenth place).
