Find the range of f(x) = 5x - 4 for the domain = {2, 4, 6}]
Sphinxa [80]

Answer:

Step-by-step explanation:

For this question they are asking you to find y when x is {2, 4, and 6}

That means you need to plug 2,4, and 6 into the equation and solve.

For example:

f(x) = 5x - 4

f(2) = 5(2) - 4

f(2) = 10 - 4

f(2) = 6

f(x) = 5x - 4

f(4) = 5(4) -4

f(4) = 20 - 4

f(4) = 16

f(x) = 5x - 4

f(6) = 5(6) - 4

f(6) = 30 - 4

f(6) = 26

Is every isosceles triangle equilateral? Is every equilateral triangle isosceles? Explain
Len [333]
Every equilateral triangle is also anisosceles triangle, so any two sides that are equal have equal opposite angles. Therefore, since all three sides of an equilateral triangle are equal, all three angles are equal, too.

radio signals travel at a rate of 3 x 10^8 meters per second. how many seconds will it take for a radio signal to travel from a
zvonat [6]

Answer:

time=1.2\times 10^{-1}\ second

Step-by-step explanation:

Given:

The speed of the radio is 3\times 10^{8} meters per second.

The distance of the satellite from the earth is 3.6\times 10^{7} meter

The formula of the speed is

speed = \frac{distance}{time}

For time the formula is.

time = \frac{distance}{speed}

put distance and speed value in above equation.

time = \frac{3.6\times 10^{7}}{3\times 10^{8}}

time = \frac{1.2 x 10^{7}}{10^{8}}

time=1.2\times 10^{7}\times 10^{-8}

time=1.2\times 10^{7-8}

time=1.2\times 10^{-1}\ second

Therefore, the radio will be take the time is 1.2\times 10^{-1}\ second or 0.12 seconds.

Alinara [238K]

Answer:

Step-by-step explanation:

Given that a teacher  gives a test to a large group of students. The results are closely approximated by a normal curve

mu =74 and sigma =8

A grade starts from 100-8 = 92nd percentile

Z score for 92nd percentile = 1.405

X score = 74+8(1.405) = 85.24

--------------------

B cut off is to next 16%

Hence C would start for scores below 100-(8+16) = 76%

76th percentile = 0.705*8+74 =79.64
