n200080 [17]3 years ago

8 0

Answer:

Step-by-step explanation:

(b - c)/b * (b+c)/b Notice how the second fraction is inverted and multiplied. That's how you handle a 4 tier fraction. Here's a simpler example

$\frac{\frac{2}{3} }{\frac{4}{5} } = \frac{2}{3} * \frac{5}{4}$

What you get with your problem is

(b^2 - c^2)/b^2

Write an equation in point slope form of the line passes through the point (9,0) and has a slope of m=-3

Brut [27]

Answer:

$\huge y = - 3(x - 9)$

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

From the question we have the final answer as

$y - 0 = - 3(x - 9) \\ \\ \\ y = - 3(x - 9)$

Paloma has a flower stand at a farmer's market. On Tuesday, she sold 8 marigold flats and 10 daisy flats. An hour before closing

Nostrana [21]

Answer:

She made $117.25

Step-by-step explanation:

Consider the provided information.

The price of marigold(M) is $5.75.

The price of daisy(D) is $6.25.

The price of roses(R) is $2.50.

The price of Lilies(L) is $3.75

She sold 8 marigold flats and 10 daisy flats. An hour before closing, she sold 5 bunches of roses at half price and 2 bunches of lilies for 1/3 of the price

Total money Paloma made = $8M+10D+5\times \frac{R}{2}+2\times \frac{L}{3}$

Now substitute the respective value

Total money Paloma made = $8(5.75)+10(6.25)+5\times \frac{2.50}{2}+2\times \frac{3.75}{3}$

Total money Paloma made = $46+62.5+6.25+2.5$

Total money Paloma made = $117.25$

Hence, she made $117.25

Find the exact values of a) sec of theta b)tan of theta if cos of theta= -4/5 and sin<0

fenix001 [56]

Answer:

$\sec\theta=-\frac{5}{4}$

$\tan\theta=\frac{3}{4}$

Step-by-step explanation:

Since the sine function and cosine function is negative hence, the angle theta must lie in 3rd quadrant.

In 3rd quadrant, tangent and cot functions are positive.

$\sec\theta=\frac{1}{\cos\theta}\\\\\sec\theta=\frac{1}{-4/5}\\\\\sec\theta=-\frac{5}{4}$

$\tan\theta=\sqrt{\sec^2\theta-1}\\\\\tan\theta=\sqrt{25/16-1}\\\\\tan\theta=\sqrt{9/16}\\\\\tan\theta=\frac{3}{4}$
