Determine whether a tangent is shown in the diagram, Yes or No?

Mathematics
1 answer:
inysia [295]3 years ago
5 0

Answer:

No

Step-by-step explanation:

If the line was a tangent, it would be perpendicular to the radius of the circle - hence there would be a 90 angle between them. Therefore we would be able to apply the Pythagorean theorem (a^2 + b^2=c^2) to determine the side lengths of a triangle that would be valid. In order for the line to be a tangent so you would say that:

3^2+9^2=90

12^2 = 144

90\neq 144

so this must not be the case.

Solve. High school pre-cal
Oliga [24]

Answer:

<em>Answer: Quadrant 4</em>

Step-by-step explanation:

<u>Graph of Functions </u>

Let's analyze the function  

\displaystyle y=\frac{x^2+3x}{x+1}

To better understand the following analysis, we'll factor y

\displaystyle y=\frac{x(x+3)}{x+1}

For y to have points in the first quadrant, at least one positive value of x must produce one positive value of y. It's evident that any x greater than 0 will do. For example, x=1 will make y to be positive in the numerator and in the denominator, so it's positive

For y to have points in the second quadrant, at least one negative value of x must produce one positive value of y. We need two of the factors that are negative. It can be seen that x=-2 will make y as positive, going through the second quadrant.

For the third quadrant, we have to find at least one value of x who produces a negative value of y. We only need to pick a value of x that makes one or all the factors be negative. For example, x=-4 produces a negative value of y, so it goes through the third quadrant

Finally, the fourth quadrant is never reached by any branch because no positive value of x can produce a negative value of y.

Answer: Quadrant 4

Write an expression so that when you divide ¼ by a number the quotient will be greater than 1/4.
SVETLANKA909090 [29]
Hello There!

An example of this would be:
\frac{6}{1/4}
6 = \frac{6}{1}
\frac{6}{1} *  \frac{4}{1}
= \frac{24}{1}
= 24

Hope This Helps You!
Good Luck :)

last week a share of stock gained a total of 1.64 points express this gain as a mixed number in simplest form
lbvjy [14]

Answer:

1  16/25

Step-by-step explanation:

1 whole and remaining decimal 0.64

0.64 is 64/100 as a fraction which simplifies to 16/25

So as a whole number its 1 + 16/25 which is 1 16/25

Hope this helps.
