Answer:

X=1

Step-by-step explanation:

It’s 2 secant lines on a circle.

https://www.mathplanet.com/education/geometry/circles/advanced-information-about-circles

Look at that website. The part says that (ab*ad)=(ac*ae)

Doing that, we get

9*(9+11x)=10(10+8x)

81+99x=100+80x

19x=19

X=1

The number of internet paid search ads is increasing as advertisers move away from traditional marketing methods. The equation y
blondinia [14]

Answer: In 2005 the amount spend on internet ads = $74.6 billions.

In 2009 spending on internet search ads will reach $102 billion .

Step-by-step explanation:

Given : The number of internet paid search ads is increasing as advertisers move away from traditional marketing methods.

The equation y=6.9x+40.1 can be used to project spending on internet search ads, in billions of dollars, x years after 2000.

To estimate spending on internet ads in 2005.

We need to put x= 5 in the above equation   [∵2005-2000=5]

y=6.9(5)+40.1

y=34.5+40.1

y=74.6

i.e. In 2005 the amount spend on internet ads = $74.6 billions.

Put y= 102 in the given equation, we get

102=6.9x+40.1

61.9=6.9x   [Subtract 40.1 from both sides]

x=\dfrac{61.9}{6.9}=\dfrac{619}{69}=8.97101449275\approx9

And 2000+9=2009 [x is the number of years after 2000]

Hence, in 2009 spending on internet search ads will reach $102 billion .

Ashirt button has a diameter of 0.61 cm. Which of these is an approximate measurement of the circumference of the button?
Aleonysh [2.5K]

Answer:

1.92cm

Step-by-step explanation:

Circumference of a circle is computed using the formula:

C=2\pi r

Where:

r = radius

π = 3.14

Since the radius is the distance of the center of the circle from any point of the circle and the diameter is the measure of a straight line that goes across the center of the circle from one side to the other, radius is half of a diameter. So the diameter = 2r.

We can then use the diameter to solve for the circumference by using the formula"

C = \pi d

So we just plug in what we know in the formula:

C = \pi d\\\\C = (3.14)(0.61cm)\\\\C = 1.9154cm\cong1.92cm

What is the slope of the line shown​
katovenus [111]

Answer:

-1/2

Step-by-step explanation:

Pick two points on the line

(-2,3) and (2,1)

Using the slope formula

m = (y2-y1)/(x2-x1)

   = (1-3)/(2 - -2)

   = (1-3)/(2+2)

    = -2/4

   = -1/2
