The position of a particle moving along the x-axis is given by a twice-differentiable function x(t). If x(2) < 0, x'(2) < 0, and x''(2) <0, which of the following statements must be true about the particle at time t=2?

a. The particle is moving toward the origin at a decreasing speed.
b. The particle is moving toward the origin at an increasing speed.
c. The particle is moving away from the origin at a decreasing speed.
d. The particle is moving away from the origin at an increasing speed.
e. The particle is moving away from the origin at a constant speed.

Answers

Answer 1

Answer:

c cuz differential of position is velocity, velocity is negative so moving away, differential of velocity is acceleration, negative acc is decreasing velocity

Megan bought 2 1/4 pounds of bananas for 0.80 per pound and 1 1/2 pounds of strawberries for 1.10 per pound how much more did Megan spend on bananas than on strawberries express the answer as dollars. Cents

Answers

Answer:

$0.15

Step-by-step explanation:

Given that:

Cost of banana per pound = $0.80

Amount of banana bought = [tex]2\frac{1}{4}=2.25\ pounds[/tex]

Cost of strawberries per pound = $1.10

Amount of strawberries bought = [tex]1\frac{1}{2} = 1.5\ pounds[/tex]

To find:

How much more money was spent on bananas than Strawberries.

Solution:

Here, first we need to find how much money was spent on bananas and strawberries.

Then we need to subtract the smaller value from larger value.

From the given values, we can calculate the following:

Cost of banana for 2.25 pounds = $0.80 [tex]\times[/tex] 2.25 = $1.8

Similarly,

Cost of strawberries for 1.5 pounds = $1.10 [tex]\times[/tex] 1.5 = $1.65

Money more spent on bananas = $1.8 - $1.65 = $0.15

5/8 divided by 3/4?
Pls answer I’ll give u brainliest

Answers

Answer:0.833333333

Step-by-step explanation:

5/8 divided by 3/4 is just 5/8 x 4/3 which is 0.833333333

Divide: 5/8 : 3/4 = 5/8 · 4/3 = 5 · 4/8 · 3 = 20/24 = 4 · 5 /4 · 6 = 5/6

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 3/

4 is 4/3) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step , cancel by a common factor of 4 gives 5/6.

Initial amount x (100%xinterest%)^(years)

My workings which I also checked with another and they agree doesn't come back to your options. But closest answer is B.

Step-by-step explanation:

$450x(1.048^4) = $542.82

$750x(1.0375^4) = $868.99

$542.82 + $868.99 = $1,411.81

Crystal works on the weekends! Last Saturday she worked 7.75 hours and on Sunday she worked 8.5 hours. She earns $12 per hour. How much did she earn last weekend?

Answers

Answer:

She earned $195 last weekend.

Step-by-step explanation:

(7.75x12)+(8.5x12)

93+102

195

$206

Expanation
7.75 7 hours (7 x $12 = 95) .75 ( 3/4 of 100) so 3/4 of 60 is 45 now when she works for 30 mins she would earn 6 dollars because it is half of 12. So if it is 45 mins she would earn 9 dollars so if we add it becomes $104

8.5 8 hours and 30 mins because.5 so 8x 12 becomes 96 + 6 ( half of 12) becomes $ 102

Answers

Answer:

x = 14

Step-by-step explanation:

Since ABCD is an isosceles trapezoid, we know that AC = BD

Therefore:

x= 3x - 28

Now we can just solve the equation for x:

x - x = 3x - x - 28

0 = 2x - 28

0 + 28 = 2x - 28 + 28

28 = 2x

28/2 = 2x/x

14 = x

x = 14
