$f(x) = \dfrac{x}{2} - 2$

$g(x) = 2x^2 + x - 3$

$(f + g)(x) = \dfrac{x}{2} - 2+ 2x^2 + x - 3$

$(f + g)(x) = 2x^2 + \dfrac{3}{2}x - 5$

What is the length of the altitude of the equilateral triangle below

AVprozaik [17]

Answer

Find out the altitude of the equilateral triangle .

To proof

By using the trignometric identity.

$tan\theta = \frac{Perpendicular}{base}$

As shown in the diagram

and putting the values of the angles , base and perpendicular

$tan 60^{\circ} = \frac{a}{4\sqrt{3}}$

$tan 60^{\circ} = \sqrt{3}$

solving

$\sqrt{3} = \frac{a}{4\sqrt{3}}$

$a = \sqrt{3}\times 4 \sqrt{3}$

$\sqrt{3}\times \sqrt{3} = 3$

put in the above

a = 4 × 3

a = 12 units

The length of the altitude of the equilateral triangle is 12 units .

Option (F) is correct .

Hence proved

lana66690 [7]

Answer:

Correct choice is B

Step-by-step explanation:

The exponential regression model can be written as exponential function

$y=a\cdot b^x.$

Then

$5,000=a\cdot b^0=a,\\ \\5,510=a\cdot b^2\Rightarrow 5,510=5,000\cdot b^2,\\ \\b^2=\dfrac{5,510}{5,000}=\dfrac{551}{500}\Rightarrow b\approx 1.05.$

Thus,

$y=5,000\cdot (1.05)^x.$

When $x=12,$ you get

$y(12)=5,000\cdot (1.05)^{12}\approx \$8,980.$
