g(x) =2x^2+3


k(x)=g(x-2)+4

k(x) = 2(x - 2)^2 + 3 + 4

k(x) = 2(x^2 - 4x + 4) + 7

k(x) = 2x^2 - 8x + 8 + 7

k(x) = 2x^2 - 8x + 15

Answer

k(x) = 2x^2 - 8x + 15

22. A liver cell is about 20 um in diameter. How many liver cells would it take to form an end to end chain 10 in long?
34kurt

The number of liver cells it would take to form an end to end chain 10 in long is 12,700 liver cells

<h3>Calculating quantity</h3>

From the question, we are to determine how many liver cells it would take to form an end to end chain 10 in long

First, we will convert 10 in to meters

1 inch = 0.0254

∴ 10 inches = 0.254 m

From the giving information,

A liver cell is about 20 μm in diameter

∴ The number of liver cells it would take to form an end to end chain 10 in long = 0.254 m / 20 μm

= 0.254 m / (20 ×10⁻⁶) m (NOTE: 1μm = 10⁻⁶m)

= 12700

Hence, the number of liver cells it would take to form an end to end chain 10 in long is 12,700 liver cells

last year a business had profits of $8000 this year it will have 5 times as great what are this yours profits
mestny [16]

We have been given that last year, the business had profit of $8000.

Further, we are given that, the profit for this year will be 5 times as great the profit of last year. So, in order to find profit of current year, we will have to consider 5 times of $8000.

Therefore, we get the profit for current year as:

\text{Profit for current year}=5\cdot8000\\\text{Profit for current year}=\$40,000

Therefore, profit for current year would be 40,000 dollars.

The trigonometric function gives the ratio of different sides of a right-angle triangle. The area of the triangle is 55.4256 ft².

<h3>What are Trigonometric functions?</h3>

The trigonometric function gives the ratio of different sides of a right-angle triangle.

\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

For the given triangle the length of AB and BC can be written as,

\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Sin(30^o) = \dfrac{AB}{AC}\\\\\\AB = Sin(30^o) \times 16 \\\\\\AB=8\rm\ ft

Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Cos(30^o) = \dfrac{BC}{AC}\\\\\\BC = Cos(30^o) \times AC\\\\\\BC = 13.8564\rm\ ft

Now, the area of the triangle is,

Area of triangle = 0.5× 8 × 13.8564 = 55.4256 ft²

Hence, the area of the triangle is 55.4256 ft².
