For the scatter plot on homework:

a) The relationship is that the test score will increase, if the time spent on homework increases.

b) The function is y=8x+40, and what we need to see is what the score will be if someone puts in 3 hours of homework, x=3 in this because it means the time spent on homework:

y=8(3)+40

y=24+40

y=64

c) The score would be 40% if no time was spent doing homework.

For the scatter plot on the rides:

a) y = -7/5x + 17.8

b) Anika worked 17.8 hours on Day 0

c) Decreased by 7/5 in a day.

Hope this helps, have a BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)

If f(x)=2x^2+6,find the value of f(-3). Show all work
goblinko [34]
Just plug -3 where x is into the equation 2x^2 + 6 and solve
f(-3) = 2(-3)^2 + 6
f(-3) = 2(9) + 6
f(-3) = 18 + 6
f(-3) = 24

Square ABCD and isosceles triangle BUC are drawn to create trapezoid AUCD. Square A B C D and triangle B U C are attached at sid
Art [367]

Answer:

d) 135º

Step-by-step explanation:

Note that the angle DCU is the sum of the angles DCB and BCU. The angle DCB is 90º because A B C D is a square, then all its angles are equal to 90º.

After attaching B U C to A B C D, we obtain a trapezoid A U C D. Since A U C D has at least one pair of parallel sides, then AU should be parallel to CD, thus the angle CBU must be 90º.

B U C is isoceles, so we conclude that other two angles must have the same size, and due to the sum of the angles of a triangle being 180º, then both BUC and BCU are equal to 45º

As a result, the angle DCU is equal to 90º+45º = 135º. Option d is the correct one.
