Please help (Could I also get help with C I took a picture of it) (15 points) Shelly has a photo that is 7 1/3 inches tall. She wants to shrink it down to fit in a picture frame that is only 5 1/3 inches tall. The photo shop can only
reduce photos by certain fractions. They can reduce it to 2/3 the original size,
the original size, 3/4 the original size. Or 5/9 the original size
A. Which reduction should she use so the picture fills as much of the frame as
possible, without being too large?

B. How much extra space is there in the frame when she uses the reduction
from Part A?

The fence around a quadrilateral-shaped pasture is 3a^2+15a+9 long. three sides of the fence have the following lengths: 5a, 10a-2, a^2-7. what is the length of the fourth side of the fence?

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 5x^2 + 10x

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
