Name them as vertices A,B,C , D and E in that order.

ab =  \sqrt{ {( - 2 + 3)}^{2} + (1 - 3)^{2}} =  \sqrt{5}  \\ bc =  \sqrt{ {( - 3 + 1)}^{2} +  {(3 - 5)}^{2}  }  = 2 \sqrt{2}  \\ cd =  \sqrt{ { (- 1 - 2)}^{2} + {(5 - 4)}^{2} }  =  \sqrt{10}  \\ de =  \sqrt{  {(2 - 2)}^{2} +  {(4 - 1)}^{2} }  = 3 \\ ea =  \sqrt{  {(2 + 2)}^{2} +   {(1 - 1)}^{2}    }  = 4 \\ peimeter = ab + bc + cd + de + ea = 15.227 \: or \: 15.23

Answer:

  (d)  domain: 0 ≤ x ≤ 4; range: -1 ≤ y ≤ 7

Step-by-step explanation:

The graph of the inverse of a function is a reflection of the function's graph across the line y=x. The table values are obtained by swapping the x- and y-labels. This is shown in the attachment.

1. When you measure the length of an object to the eighth of an inch and again to the fourth of an inch, which measurement is mo
sladkih [1.3K]

Answer:

The eighth of an inch scale measures more precisely.

Step-by-step explanation:

An eighth of an inch means that one inch is divided into 8 equal lengths on the scale i.e. the minimum length that can be measured is \frac{1}{8} =0.125 inch.

Again a fourth of an inch means that one inch is divided into 4 equal lengths on the scale i.e. the minimum length that can be measured is \frac{1}{4} =0.25 inch.

Therefore, the eighth of an inch scale measures more precisely as it can measure more small measurements. (Answer)

Explain how the sign of a in the equation y=a(x-h)^2 + k tells you whether the parabola has a minimum or maximum value.
Svet_ta [14]
In short, for a vertical parabola, namely one whose independent variable is on the x-axis, usually is x², if the leading term coefficient is negative, the parabola opens downward, and its peak or vertex is at a maximum, check the picture below at the left-hand-side.

and when the leading term coefficient is positive, the parabola opens upwards, with a minimum, check the picture below at the right-hand-side.

A population of 100 frogs has a growth rate of 1.25% each month. At this growth rate,
Dmitriy789 [7]

Answer: 7.2 months

Step-by-step explanation:

Hi, to answer this question we have to substitute f(x) =500 in the equation given:

f(x) = 100(1.25)^x

500= 100(1.25)^x

Solving for x (number of months)

500/100 = 1.25^x

5 = 1.25^x

log 5 =log 1.25^x

log 5 =x (log 1.25)

log 5 /log 1.25 =x

x = 7.2 months

Feel free to ask for more if needed or if you did not understand something.
