Assume body weight and height are related by the formula W=2H+13, where W represents weight in pounds and H represents height in
yulyashka [42]
Given the equqation
W = 2H + 13
where
W is the weight in lb
H is the height in inches

If the height of a person is 5 ft 6 in, we must first convert it to inches. So,
H = 5(12) + 6
H = 66 in

The body weight then is,
W = 2(66) + 13
W = 145 lbs

Which of the following constants can be added to x2 - 3x to form a perfect square trinomial?
jeka57 [31]

<em>Answer:</em>

<em>2 whole 1/4</em>

<em>Step-by-step explanation:</em>

<em>When forming a perfect square trinomial you need to "complete the square". </em>

<em>All of the steps to completing the square when solving an equation: </em>

<em>1.  The leading coefficient must be 1.  </em>

<em>2.  Divide b by 2. </em>

<em>3.  Square (b/2) </em>

<em>4.  Add (b/2)^2 to both sides to keep the polynomial balanced. </em>

<em>5.  You can now write the perfect square trinomial and solve. </em>

<em><u> </u></em>

x^2 - 3x  

-3/2

(-3/2)^2 = 9/4 = 2 1/4

Which of the following graphs of exponential functions corresponds to a geometric sequence with a first term of 4 and a ratio of
ser-zykov [4K]

Answer: graph E.


A geometric sequence can be written as:

a_{n} = a_{1} \cdot r^{(n - 1)}

where:

a₁ = first term = 4

r = ratio = 0.5


Substituting the numbers, we have:

a_{n} = 4 \cdot (\frac{1}{2})^{n-1}

or else

f(x) = 4 \cdot (\frac{1}{2})^{x - 1}


This is an exponential function with base less than 1. Therefore, we can exclude graph C (which depicts a linear function), and graphs A and D (which depict an exponential function with base greater than 1).


In order to choose between graph B and E, let's evaluate the function in two different points:

f(1) = 4 \cdot (\frac{1}{2})^{1 - 1} = 4

f(2) = 4 \cdot (\frac{1}{2})^{2 - 1} = 4 \cdot \frac{1}{2} = 2


Therefore, we need to look for the graph passing through the points (1, 4) and (2, 2). That is graph E.
