If a transformation maps a \mapsto b, then b is the image of a, and a is the preimage of b. So,

  • the image of a is b
  • the preimage of b is a
  • the image of c is d
  • the preimage of d is c

Which graph shows the solution to the equation below? log Subscript 3 Baseline (x + 3) = log Subscript 0.3 (x minus 1) On a coor
Effectus [21]

Answer:

On a coordinate plane, 2 curves intersect at (1, 1). One curve curves up and to the right from quadrant 3 into quadrant 1. The other curve curves down from quadrant 1 into quadrant 4

Step-by-step explanation:

The first function is given as:

log_3(x+3)

The second function is given as:

log_{0.3}(x-1)

First we graph both the functions.

We can see that one curves up and to the right from quadrant 3 into quadrant 1. This curve is of  log_3(x+3)

The other curve curves down from quadrant 1 into quadrant 3

Both curves interest almost at (1,1)

See the graph attached below

Blue line represents first function

Green line represents second function

The solution lies on the Red line.

Find the widest range of scores that you can get on a final exam in order to receive a grade of B for the class. Using interval
Drupady [299]

Answer:

Correct choice is B

Step-by-step explanation:

Let x% be your final test score, then the average of all test scores is

\dfrac{96+77+74+x}{4}.

Since you must have an average between 80% and 89%, then

80\le \dfrac{96+77+74+x}{4}\le 89,\\ \\320\le 247+x\le 356,\\ \\73\le x\le 109.

X is measured in percent, then the greatest value of x can be 100%. You get that

73\%\le x\le 100%.

Sam found that 25% of the 236 patients he saw in a week were near-sighted. How many of the patients Sam saw were near-sighted?Sa
iris [78.8K]

Answer:

59 patients

Step-by-step explanation:

Total patients Sam saw in a week = 236

Percentage of patients near-sighted = 25%

How many of the patients Sam saw were near-sighted?

Number of patients near-sighted = 25% of 236

= 25/100 × 236

= 0.25 × 236

= 59

Number of patients near-sighted = 59 patients

The number of patients Sam saw in a week that were near-sighted is 59 patients
