Answer:

x=5

y=22

Step-by-step explanation:

By definition a kite is a quadrilateral where contiguous segments are congruent therefore

4x-3 = 2x+7      and    2x = 10    so  x = 5

Remember that the sum of the interior angles of a polygon is equal to 180(n-2)

where n is the number of sides on the polygon. For this case n=4 so we know that

5y+5y+61+79 = 180*2

Therefore

10y +140 = 360

and then

y = 22

On a scale drawing 2 centimeters represent 50 meters. How many centimeters represent 5 meters?
Tanya [424]

Answer:

0.2 centimeters

Step-by-step explanation:
Strategy 1:

Make the equation: 5=a•s, where s is the scale factor and "a" is the number of centimeters which 5 meters

First, we need to find the scale factor. 50 meters would be s times greater than 2 centimeters. Find s by first converting meters into centimeters
50m=5000cm. 5000cm=2cm*s, so s = 2500
5m=a*2500, a=0.002 meters, and 0.002 meters is equal to 0.2 centimeters.

Strategy 2:
the ratio of the scale drawing to real life will always stay the same, so
2 cm / 50 meters = x / 5 meters, and cross multiply to get
x cm* 50 m = 2 cm * 5 m, so
x cm * 10 = 2 cm
x cm = 2/10 cm
x cm = 0.2 cm

Strategy 3:
Notice that 5 meters is 10 times smaller than 50 meters, so on the scale drawing, we are looking for a number 10 times smaller than 2 centimeters, so  2/10=0.2 cm

I NEED HELP PLEASE!
olchik [2.2K]

The given sequence is x-1, -2x+2, 4x-4, -8x+8 .

Notice that this is a geometric sequence because here we have equal common ratio.

So, common ratio : r = \frac{a_{2}}{a_{1}}

= \frac{-2x+1}{x-1}

= \frac{-2(x-1)}{(x-1)}Take out -2 as common factor

= -2 Cancel out x - 1.

The formula for general term of a geometric sequence is,

a_{n} =a_{1} r^{n-1}

Where, first term: a_{1} =x-1

We need to find the 10th term of this sequence. So, n = 10.

Next step is to plug in these values in the above formula to get the 10th term. Hence,

a_{10} = (x -1)(-2)^{10-1}

So, A is the correct choice.

Which polynomial could have the following graph?
Elis [28]

 

The graph shows the solutions:

x1 = -3    ⇒  x + 3 = 0

x2 = 1     ⇒  x - 1 = 0

x3 = 5     ⇒  x - 5 = 0

The polynomial follows:   y = (x + 3)(x - 1)(x - 5)

.
