The center of the circle is drawn in an isosceles triangle with a height ratio of 12: 5, the side is equal to 30 cm. Find the AC

Answers

Answer:

25cm

Step-by-step explanation:

**see attached diagram**

Let BH = h  (height)

OH = radius r = (5/17)h   ⇒  h = (17/5)r

Area ∆ABC = 1/2 × base × height  = 1/2 x AC x h

substituting  h = (17/5)r:                  = 1/2 x AC x (17/5)r

                                                        = 17/10 × AC × r

We can split the isosceles triangle into three separate triangles indicated by the red lines on the diagram attached.  Because the radius always meets a tangent (points E, D and H) at a right angle, the area of each triangle will be the length of the side multiplied by the radius of the circle:

Area ∆BOC = Area ∆BOA = 1/2 × 30 × r = 15r

Area ∆AOC = 1/2 × AC × r = 1/2 × AC × r

Therefore, area ∆ABC = ∆AOC + ∆BOC + ∆BOA

                                      =1/2 (AC)r + 15r + 15r

                                      =1/2 (AC)r + 30r

Now we have 2 different equations for the area of the isosceles triangle ABC.  Equate both equations and solve to find AC:

                                                 Area ∆ABC = Area ∆ABC

                                                   17/10 (AC)r = 1/2 (AC)r + 30r

Divide both sides by r:               17/10 (AC) = 1/2 (AC) + 30

Collect & combine like terms:      6/5 (AC) = 30

Divide by 6/5:                                        AC = 25 cm

For the x-values 1, 2, 3, and so on, the y-values of a function form an
arithmetic sequence that decreases in value. What type of function is it?
O
A. Exponential growth
O B. Decreasing linear
O c. Exponential decay
C.
O D. Increasing linear

Answers

Answer:

B. Decreasing linear

Step-by-step explanation:

Arithmetic sequence has a linear behavior since its common difference is the slope of the line.

If y-values decrease as x-values increase then this is a decreasing function.

Correct choice is B

Answer:

Decreasing linear

Step-by-step explanation:

As x values like 1,2,3.. are decreasing with respect to y hence it's decreasing function

Also

Arithmetic progression is linear hence it's decreasing linear

Answers

Answer:

93/100

Step-by-step explanation:

23/100 + 7/10

=> 23/100 + 70/100

=> 93/100

Answer and Step-by-step explanation:

First, before you add and solve, you need to make both denominators the same. So, multiply the numerator and denominator of 7/10 by 10 to get: 70/100. Now you should have:

23   +   70

100         100

Simply add the numerators to get 93/100. This cannot be simplified any further, so the final answer is:

93

100

The English expression is ambiguous in that we cannot tell if the number is decreased by 10 before becoming part of the product (9(n-10)), or if the correct interpretation is the one shown above. The order of operations is used as a guide, telling us that the multiplication is done before the subtraction since there is no indication of grouping.

890/89=10%

Check Answer:

89 x 10%=8.90

89+8.90= 97.90

determine whether this advertisement is correct.

Answers

Discount are used to reduce the costs of items

The percent paid to determine the advertisement is incorrect

How to determine the correct percentage

The initial prices are given as: $44.00 to $152.00

And the discount is: 45% to 51%

At a discount of 45%, the price of the items would be:

[tex]Price = \$44.00 * (1 - 45\%)[/tex]

[tex]Price = \$24.2[/tex]

[tex]Price_2 = \$152.00 * (1 - 45\%)[/tex]

[tex]Price_2 = \$83.6[/tex]

At a discount of 51%, the price of the items would be:

[tex]Price = \$44.00 * (1 - 51\%)[/tex]

[tex]Price = \$21.56[/tex]

[tex]Price_2 = \$152.00 * (1 - 51\%)[/tex]

[tex]Price_2 = \$74.48[/tex]

The calculates prices show that the percent paid to determine the advertisement is incorrect

How do you determine what side of a graph should be x and what side is y when graphing a scatterplot in linear regression?? For instance, in the problem below:

Answers

Answer:

y will be the dependent variable, and x will be the independent variable.

So y is affected by x.

Regarding the problem you attached, consider if IQ affects job performance, or if job performance affects IQ.

I would say that IQ may affect job performance (as job performance does not affect IQ), so in this case x will be IQ and y will be job performance.

When data is presented in tables, it is usual for the x values to be on the left and the y values to be on the right (though, not in every case, of course!).

Assuming that you use polynomial math and (x-h)^2 + (y-k)^2 = r^2 and the data contained in the directions (x,y) of every city, you can track down h, k and r. Then, at that point, r is the (equivalent) distance between every city and the focal point of the circle, where the new pinnacle will be assembled.
