Answer:

Step-by-step explanation:

Important things to know:

The sum of the angles in any triangle is equal to 180º

An isosceles triangle has two angles that are equal in measurement, while the third one is not

Answer:

40 degrees.

Step-by-step explanation:

As it has 2 equal sides it is an isosceles triangle and it also has 2 equal angles. The other angle cannot be 100 degrees because that is greater than 180 degrees, so the two equal angles must sum to 180 - 100 = 80 degrees.

Each angle measures 40 degrees.

These are the first six terms of a sequence with a1= -7:
SVEN [57.7K]

The recursive formula for this sequence is a_{1} = -7;  a_{n} = a_{n-1} + 10

Step-by-step explanation:

The recursive formula of the arithmetic sequence is:

a_{1} = first term;  a_{n} = a_{n-1} + d

  • a_{1} is the first term in the sequence  
  • a_{n} is the nth term in the sequence  
  • a_{n-1}  the term before the nth term  
  • n is the term number
  • d is the common difference

∵ The sequence is -7 , 3 , 13  , 23 , 33 , 43 , ........

∵ 3 - (-7) = 3 + 7 = 10

∵ 13 - 3 = 10

∵ 23 - 13 = 10

- There is a constant difference 10 between the consecutive terms

∴ The sequence is an arithmetic sequence

∵ The first term is -7

∴ a_{1} = 7

∵ The common difference is 10

∴ d = 10

- Substitute in the formula above a_{1} by -7 and d by 10

∴ a_{1} = -7;  a_{n} = a_{n-1} + 10

To check the formula find the second term

∵ n = 2

∴ a_{1} = -7;  n_{2} = n_{2-1} + 10

∴  n_{2} = n_{1} + 10

∵ n_{1}  = -7

∴ n_{2} = -7 + 10 = 3 which is right

The recursive formula for this sequence is a_{1} = -7;  a_{n} = a_{n-1} + 10

Write the equation in slope intercept form. what are the slope and y-intercept? -3x - 10y = 7
Anarel [89]

Answer:

Slope: = 3/10x

y-intercept: = -7/10

Step-by-step explanation:

10y = -3x - 7

y = -3/10x - 7/10

Slope: = 3/10x

y-intercept: = -7/10

Which results only in a horizontal compression of Y = by a factor of 6?
elena55 [62]

Answer:

Y = 6*y

Step-by-step explanation:

We have Y = b * y by a factor of 6.

That is, b = 6.

now, to find what results only in a horizontal compression of y = b * y by a factor of 6.

By transformation rule, the function would be a horizontal compression f (a * x) if a> 1.

Therefore, knowing the above, the answer would be:

Y = 6 * y
