Which number is the best approximation for 47√− 23√ ?

2 answers:

4 0

Let's round the numbers into perfect roots. So 23 rounded would be 25, because the square root of 25 is 5, and 47 rounded is 49, because the root of 49 is 7. So 7-5=2. That would be the best approximation for this question.

The graph of f passes through left parenthesis negative 4 comma 3 right parenthesis(−4,3) and is perpendicular to the line that

shusha [124]

Answer:

The answer to your question is y = -11/2x - 19

Step-by-step explanation:

Data

Point (-4, 3)

⊥ to the line x- intercept of 22 and y-intercept of -4.

Process

1.- Find the equation of the perpendicular line

This line has passes through the points (22, 0) and (0, -4)

Slope = $\frac{-4 - 0}{0 - 22} = \frac{-4}{-22} = \frac{2}{11}$

2.- Find the slope of the new equation

Slope = $\frac{-11}{2}$ because the lines are perpendicular

3.- Find the equation of the new line

y - 3 = -11/2 (x + 4)

y - 3 = -11/2x - 44/2

y - 3 = -11/2 x - 22

y = -11/2 x - 22 + 3

y = -11/2x - 19

See the graph below

Four of the angles of a pentagon have measures 40, 80, 115, and 165. Find the measure of the fifth angle. ...?

Tresset [83]

The sum of the interior angles of a pentagon is 540 degrees. We find the measure of the fifth angle by summing up the four angles given and subtracting this to the total sum. We calculate as follows:

Fifth angle = 540 - (40+80+115+165) = 140 degrees

Hope this answers the question.
