A tangent line creates a 90 degree angle with a radius line that touches the tangent Line.

Line BC is a radius that touches the tangent line at point C

The angle created is 90 degrees.

The answer is C. 90 degrees.

Slope intercepts <br> No links, Will mark BRAINLIEST

Sergeeva-Olga [200]

Answer:

<em><u>Lines are perpendicular to each other .</u></em>

Step-by-step explanation:

Standard equation of line is : y = mx + c, Where m represents the slope

Given Equations :

$y = -5x + 1\\\\Slope , m_1 = -5$

$y = \frac{1}{5}x +1\\\\Slope, m_2 = \frac{1}{5}$

Two lines are parallel if the slope of the lines are same.

Two line are perpendicular if the product of the slope = - 1

Clearly slopes are not equal , therefore the lines are not parallel.

product of the slope is - 1, therefore the lines are perpendicular.

$m_1 \times m_2 = -5 \times \frac{1}{5} = - 1$

30 POINTS By looking at the intercepts, which linear function does the graph represent?

larisa86 [58]

C. f(x)=2/3x-2

<h2>Explanation:</h2>

Looking at the graph we realize that the y-intercept is given by:

$b=-2$

The Slope-intercept form of the equation of a line is given by:

$y=mx+b$

So, our equation becomes:

$y=mx-2$

So the only option that matches a negative y-intercept is C. Let's see that the slope $m=2/3$ . Look at the y-intercept, if you increase x by 3 units, then y increases by 2 units and goes from $x=-2$ to $x=0$ . In other words:

$Change \ in \ x=\Delta x=3 \\ \\ Change \ in \ y=\Delta y=2 \\ \\ \\ m=\frac{\Delta y}{\Delta x}=\frac{2}{3}$

Frank has 24 pennies, 62 nickels, 55 dimes, 16 quarters, and 19 fifty-cent pieces. How much money does he have?

erik [133]

Answer:

$22.34

Step-by-step explanation:

24 pennies is .24 of a dollar

62 nickels will be: (62 x 5) / 100 = 3.10

55 dimes is 5.5

16 quarters will be 4.0

19 fifty-cents will be 9.5

Add them up to get $22.34 if I’m right.

Hope this helped.
