The 3rd and 6th term of a geometric progression are 9/2 and 243/16 respectively find the first term, common ratio, seventh term​
sashaice [31]

Answer:

Hello,

Step-by-step explanation:

Let\ (u_n)\ the\ geometric\ progression.\\\\r\ is\ the\ common\ ratio.\\\\u_3=u_0*r^3\\u_6=u_0*r^6\\\\\dfrac{u_6}{u_3} =r^3=\dfrac{\frac{243}{16} }{\frac{9}{2} } =\dfrac{27}{8} =(\frac{3}{2} )^3\\\\\boxed{r=\dfrac{3}{2} }\\\\\\u_3=u_1*r^2 \Longrightarrow\ u_1=\dfrac{u_3}{r^2} =\dfrac{\frac{9}{2} }{(\frac{3}{2^2}) } =2\\\\\\u_7=u_6*\dfrac{3}{2} =\dfrac{729}{32}

A baseball coach bought some bats and gloves for the school's baseball team.the bats cost $20 to $35,and gloves cost $30 to $60.
arlik [135]

Max cost of 15 bats = 15 x 35 = $535

Min cost of 15 bats = 15 x 20 = $300


Max cost of 12 gloves = 12 x 60 = $720

Mix cost of 12 gloves = 12 x 30 = $360


Min total cost = 360 + 300 = $660

Max total cost = 535 + 720 = $1255

The range is from  $660 to $1255

=============> Answer (A) is out of the range

Solve 5n^2=5 with the quadratic formula
Yanka [14]

Answer:

n = 1

Step-by-step explanation:

First, rearrange the equation to standard form 0 = ax² + bx + c, when everything equals 0.

5n² = 5

5n² - 5 = 0

State the variables a, b and c.

a = 5;  b = 0;  c = -5

Substitute a, b, and c into the quadratic formula.

n = \frac{-b ±\sqrt{b^{2}-4ac} }{2a}

n = \frac{-0 ±\sqrt{0^{2}-4(5)(-5)} }{2(5)}   Substitute

n = \frac{\sqrt{100} }{10}   Simplify inside the √ and bottom

n = \frac{10}{10}  Simplify the top

n = 1  Final answer

Therefore the solution is n = 1.

The quadratic formula usually is written with x, but it can be solved with any variable in standard form.
