Answer:8 1/4 cups

Step-by-step explanation:

All you must do is multiply 2.75 (which is 2 3/4 in decimal form) by 3 since Wendy is baking a TRIPLE recipe. So, the work will look like this: 2.75x3=8.25 or 8 1/4 cups of flour.

Please help with this precalc!!! i desperately need help

Paladinen [302]

Step-by-step explanation:

4 is the A or Ampltiude

To find the period set it equal to 2 pi/B

$\frac{2\pi}{b} = \frac{6}{1}$

$\frac{b}{2\pi} = \frac{1}{6}$

$\frac{2\pi}{6}$

$\frac{\pi}{3}$

There is no phase shift

The midline or d or vertical shift is 1.

Our equation for 8 is

$4 \sin( \frac{\pi}{6} x) + 1$

9.Use sin function. The a value is 2 or -2 your choice.

Set up the period equal to the equation

$\frac{2\pi}{b} = \frac{\pi}{3}$

$\frac{b}{2\pi} = \frac{3}{\pi}$

$b = \frac{3}{\pi} \times 2\pi$

Which equal 6.

B=6

There is no C and the D and Vertical Shift is 1.

Our equation is

$2 \sin(6x) + 1$

What is the 399,713 rounded to the place value of the third underlined digit of 399

maksim [4K]

The <em>correct answer</em> is:

400,000.

Explanation:

The third digit in 399 is 9. To round to this place value, we inspect the digit behind it. If the digit is 5 or greater, we round up; if it is less than 5, we round down.

The digit behind 9 is 7. Since it is greater than 5, we round up. This would ordinarily put the number up 1; however, doing that makes the 9 a 10, which in turn makes the next number 10, and the next number 4. This gives us 400,000.
