RT = sqrt(20^2 - 16^2)
RT = sqrt(400 - 256)
RT = sqrt(144)
RT = 12

SR/ST=  QR/QT
SR/12 = 20/16
SR = 12 x 20 / 16
SR = 240/16
SR = 15

answer is C.
15 Units

Please help. Write the equation of the graph. (Do not use spaces. Use ^ to represent exponents. Example 2^3 is 23.)
lana66690 [7]
This graph has a horizontal asymptote so it is an exponential graph. It also passes through two points (0,-2) and (1,3). The horizontal asymptote is at y=-3.
The unchanged exponential equation is y=a(b)^x +k
For exponential equations, k is always equal to the horizontal asymptote, so k=-3.
You can check this with the ordered pair (0,-2). After that plug in the other ordered pair, (1,3).
This gives you 3=a(b)^1 or 3=ab. If you know the base the answer is simple as you just solve for a.
If you don't know the base at this point you have to sort of guess. For example, let's say both a and b are whole numbers. In that case b would have to be 3, as it can't be 1 since then the answer never changes, and a is 1. Then choose an x-value and not exact corresponding y-value. In this case x=-1 and y= a bit less than -2.75. Plug in the values to your "final" equation of y=(3)^x -3.
So -2.75=(3^-1)-3. 
3^-1 is 1/3, 1/3-3 is -8/3 or -2.6667 which is pretty close to -2.75. So we can say the final equation is y=3^x -3. 
Hope this helps! It's a lot easier to solve problems like these given either more points which you can use system of equations with, or with a given base or slope.

William has a 26 -liter glass tank. First, he wants to put some marbles in it, all of the same volume. Then, he wants to fill th
madreJ [45]

Subtract the volume of the water from the volume of the tank to get the total volume of the marbles.

26 liters - 20.9 liters = 5.1 liters

He has 20.9 liters of water.

He has 85 marbles that add up to 5.1 liters of volume.

To find the volume of one marble, we divide 5.1 liters by 85.

(5.1 liters)/85 = 0.06 liters

The volume of each marble is 0.06 liters.

If he uses 200 marbles, the the marbles will occupy 200 * 0.06 liters = 12 liters.

The volume of the tank is 26 liters. 12 liters of volume is occupied by the marbles. The rest of the volume is water.

26 liters - 12 liters = 14 liters

HELP PLEASE
Elis [28]

Answer:

  • 2 ≤ x < 9 or x = [2, 9)

Step-by-step explanation:

<u>Negative four is at least six less than a number</u>

  • -4 ≤ x - 6 ⇒ x ≥ 2

<u>Sum of a negative two & nine times a number is less than seventy nine</u>

  • -2 + 9x < 79  ⇒ 9x < 81 ⇒ x < 9

<u>Combined inequality:</u>

  • 2 ≤ x < 9 or x = [2, 9)

<h3>What is a Polynomial?</h3>

A polynomial is an algebraic expression which may be of varying degrees or number of terms.

According to the question;

  • The expression given is; 8y.

Since, the highest degree of the variable, y is one; we can conclude that the polynomial is of degree one.

Additionally, since there's only one term in the polynomial, we can conclude it is a monomial.
