Answer:

m<B = 62°

Step-by-step explanation:

Given that ∆ABC is congruent to ∆TUV, it follows that their corresponding angles are equal to each other. Therefore:

m<B = m<U

m<B = (3y + 2)°

m<U = (4y - 18)°

Thus,

3y + 2 = 4y - 18

Collect like terms

18 + 2 = 4y - 3y

20 = y

y = 20

m<B = (3y + 2)°

Plug in the value of x

m<B = 3(20) + 2

m<B = 60 + 2

m<B = 62°

Which sequence is geometric

Vitek1552 [10]

If a, b, c, d is geometric sequence, then

$\dfrac{b}{a}=\dfrac{c}{b}=\dfrac{d}{c}=const.$

A. 5; 15; 25; 35

$\dfrac{15}{5}=3;\ \dfrac{25}{15}=\dfrac{5}{3}-NOT$

B. 5; 10; 20; 40

$\dfrac{10}{5}=2;\ \dfrac{20}{10}=2;\ \dfrac{40}{20}=2-YES$

C. 6; 12; 18; 24

$\dfrac{12}{6}=2;\ \dfrac{18}{12}=\dfrac{3}{2}-NOT$

D. 7; 14; 21; 28

$\dfrac{14}{7}=2;\ \dfrac{21}{14}=\dfrac{3}{2}-NOT$

The equation of a circle is

sergij07 [2.7K]

Answer:

The answer is

<h3>center = ( - 7 , - 1)</h3><h3>radius = 6</h3>

Step-by-step explanation:

The general equation of a circle is given by

where the center of the center of the circle is given by

From the question the equation is

x² + y² + 14x + 2y + 14 = 0

Comparing with the general equation above we have

2g = 14 2f = 2

g = 7 f = 1 c = 14

So the center of the circle is

The radius of a circle is given by

$r = \sqrt{ {g}^{2} + {f}^{2} - c}$

where

g = 7

f = 1

c = 14

Substitute the values into the above formula

That's

$r = \sqrt{ {7}^{2} + {1}^{2} - 14 } \\ r = \sqrt{49 + 1 - 14} \\ r = \sqrt{36}$

we have the final answer as

<h3>radius = 6</h3>

Rewrite 6/9 two different ways

soldi70 [24.7K]

You can multiply a fraction with the same numerator and denominator like 2/2, which is also one (does not change original fraction).
6/9*2/2= 12/18
or any other number
6/9*3/3=18/27
