Answer:

a = 98⁰

Step-by-step explanation:

According to the the triangle sum thereom, all angles in triangle add up to 180⁰.

m<a + m<b + m<c = 180⁰

m<a + <u>34⁰ + 48⁰</u> = 180⁰

m<a + 82⁰ = 180⁰

m<a + <u>82⁰ - 82⁰</u> = <u>180⁰ - 82⁰</u>

m<a = 98⁰

Hope this helps, thank you :) !!

Can someone help me correct number 6 please and thank you! Please Explain and Show Your Work!
NNADVOKAT [17]

Answer:

You have your x and y mixed up

Step-by-step explanation:

Look at your table.  You labeled y1 and y2 where the x's are.  y2 = 8, y1 = 4, x2 = 12 and x1 = 6.  The slope then is (8-4)/(12-6) which is 4/6 or 2/3.  You did run over rise instead of rise over run.  Be careful.  I see that a lot when I teach the concept to beginners.

If one root of the equation is 4x^2- 2x+p-4 be the reciprocal of other. then find the value of p​
SashulF [63]

Answer:

p = 8

Step-by-step explanation:

Let one root of the eqn. be alpha . Other root is 1/alpha .

We know that product of both roots of an quadratic eqn. is c/a where "c" is the co-efficient of the constant  & "a" is the co-efficient of x^2.

Here "c" is p-4 & "a" is 4. And the product of roots is 1 ( ∵ prdouct of a number and its reciprocal is 1 )

\frac{c}{a} = 1\\=> \frac{p - 4}{4} = 1\\=> p - 4 = 4\\=> p = 4 + 4 = 8

Use the properties of geometric series to find the sum of the series. for what values of the variable does the series converge t
Oksi-84 [34.3K]

Answer:

- The sum of the series is given as

7/(1 + 7z)

- The series converges for (-1/7, 1/7)

Step-by-step explanation:

Given the geometric series:

7 - 14z + 28z² - 56z³ + ...

The common ratio r is given as

-14z/7 or 28z²/(-14z) or -56z³/(28z²) and so on

r = -7z

The sum of the series is given as

S = a/(1 - r)

Where a is the first term in the series.

S = 7/(1 -(-7z))

= 7/(1 + 7z)

The series converges for |-7z| < 1

That is for -1/7 < z < 1/7
