Which formula is best used to prove that a figure has congruent sides?
Mazyrski [523]

Answer:

D

Step-by-step explanation:

Congruent sides mean that they have "EQUAL" lengths.

So, to prove to sides are congruent means that their lengths are equal.

Slope gives the slope of a line. So this can't be it.

Area gives the area of figure. Nothing to do with congruency of 2 lines.

Midpoint formula gives the coordinates of the midpoint. Nothing here.

Distance formula gives the length of sides. So, this is the one we can use to prove that a figure has congruent sides. We can place the figure in coordinate system and find the length of 2 respective sides using "distance formula"

Correct answer is D

7(w+2)+0.5w=5<br> What is W if the answer is 5?
V125BC [204]

Answer:

The answer to your question is w = 1.2

Step-by-step explanation:

Data

Equation                           7(w + 2) + 0.5w = 5

Expand                               7w + 14 + 0.5w = 5

Simplify like terms             (7w + 0.5w) + 14 = 5

                                            7.5w + 14 = 5

Subtract 14 in both sides

                                            7.5w + 14 - 14 = 4 - 15

Simplify

                                            7.5w = - 9

Divide both side by 7.5      7.5/7.5w = 9/7.5

Simplify

                                             w = 1.2

Find the tenth term of the geometric sequence, given the first term and common ratio.
Natalija [7]

Answer:

a_{10}=\dfrac{1}{128}

Step-by-step explanation:

In the geometric series:

a_1=4\\ \\r=\dfrac{1}{2}

The nth term of the geometric sequence can be calculated using formula

a_n=a_1\cdot r^{n-1}

In your case, n = 10, then

a_{10}\\ \\=4\cdot \left(\dfrac{1}{2}\right)^{10-1}\\ \\=4\cdot \left(\dfrac{1}{2}\right)^9\\ \\=2^2\cdot \dfrac{1}{2^9}\\ \\=\dfrac{1}{2^{9-2}}\\ \\=\dfrac{1}{2^7}\\ \\=\dfrac{1}{128}
