1) Cecilia wants to switch over to T-Mobile for the unlimited everything plan for $89.99 which includes 20GB of 4G LTE each month; if she goes over 20GB per month T-Mobile will charge Cecilia $10 for each 1 GB over her
limit. Mr. D wants to switch over to Cricket for the unlimited plan for $59.99 which includes 15GB of 4G LTE
per month, if he goes over the 15GB per month Cricket will charge Mr. D $5 for for each 1 GB over his limit.
Which system of equations represent the situation? Let x represent the overage of GB's each month.
sy = 89.99x + 10
y = 59.99x + 5
(y = = 89.99 + 10x
b.
y = 59.99 + 5x
(y = 89.99 + 5x
y = 59.99 +10x
(y = 89.99x + 5
d.
= 59.99x + 10
a.
c.

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
