the sum of all but one interior angle of a heptagon is 776°. what is the measure of the final interior angle?
soldi70 [24.7K]

Answer:

The final interior angle = 124°

Step-by-step explanation:

A heptagon has 7 sides. The sum of the interior angles formula:

The sum of the interior angles =  (n - 2)180 where n = number of sides.

The sum of the interior angles= (7 - 2)180° = 900°

Six interior angles = 776°.

The final interior angle + six interior angle = 900°

The final interior angle + 776° = 900°      

The final interior angle = 900° - 776°

The final interior angle = 124°

Write the quadratic equation y= x^2 -6x = 7 in vertex form.
lapo4ka [179]

Answer:

(x - 3)² - 16 = 0

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Subtract 7 from both sides

x² - 6x + 7 = 0 ← in standard form

with a = 1, b = - 6

Given a quadratic in standard form then the x- coordinate of the vertex is

x_{vertex} = - \frac{b}{2a} = - \frac{-6}{2} = 3

Substitute x = 3 into the equation for y

y = 3² - 6(3) - 7 = 9 - 18 - 7 = - 16 ⇒ (h, k) = (3, - 16)

y = (x - 3)² - 16 = 0

Joanna ran a mile in physical education class. After resting for one hour, her heart rate was 60 beats per minute. If her heart
umka2103 [35]
<span>Let x be Joanna's heart rate immediately after running one mile. After this heart rate x decreased by 2 over 5, Joanna's heart rate was 60 beats per minute. We can set up an equation to solve this question. x - (2/5) x = 60 (3/5) x = 60 x = (5/3) 60 x = 300 / 3 x = 100 Joanna's heart rate immediately after running one mile was 100 beats per minute.</span>

Give an algebraic representation of these data<br>x|y<br>1|1<br>4|7<br>7|13<br>10|19​
Zolol [24]

Answer:

y = 2x - 1

Step-by-step explanation:

Slope

for every increase of 3 in x

there's an increase of 6 in y

m = rise/run

m = 6/3

m = 2

----------------------------

Slope intercept form is

y = mx + b

To find "b" plug in m = 2 and any of the given points

using (1, 1)

1 = 2(1) + b

1 = 2 + b

b = -1

The equation is

y = 2x - 1
