Answer:

b and c

Step-by-step explanation:

"In mathematical logic, the Law of Detachment says that if the following two statements are true:

(1) If p , then q .

(2) p"

If the following statements are true, use the Law of Detachment to derive a new true statement:

(3) q .

So,

If an object is square, then it's a rectangle. If it is a rectangle, the sum of the measures of it's integers angles is 360°. Therefore, if an object is square, then the sum of it's measures of it's integer angles is 360°. False a square and rectangle don't have the same measurement.

Odd numbers are not divisible by 2. sixty-five is an odd number. Therefore, 65 is not divisible by 2 is a true statement

If Mary makes at least 50 sales in a month, then her company will give her a $1000 bonus. Mary made 63 sales this month. She will receive a $1000 bonus. True, 63 is more than 50.

If John finishes his homework, then he'll go out with his friends. If John goes out with his friends, then they will go to the movies. Therefore, if John finishes his homework, then he will go to the movies. Incorrect John AND his friends will go to the movies, not just John.

The function -6t^2+5t+56=h is used to calculate the amount of time (t) in seconds it takes for an object to reach a certain heig
seraphim [82]

Answer:

3.5 seconds

Step-by-step explanation:

h(t) is a quadratic function, it indicate that the object start with initial height (56).

If you want to know when the object hit the ground (h=0) you have to use the quadratic formula (-b +- \sqrt{b^{2}-4ac } )/2a and take the positive root (the negative shows a negative time, so we have to discard it).

In this case: a=-6, b=5 and c=56, then the solve is 7/2=3.5

Please i need help :(
Nezavi [6.7K]

Answer:

37 units

Step-by-step explanation:

\boxed{distance =  \sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}  }}

Using the distance formula above,

distance between (15, -17) and (-20, -5)

=  \sqrt{[15 - ( - 20)]^{2}  + [ - 17 - ( - 5)] {}^{2} }  \\  =  \sqrt{(15 + 20)^{2} + ( - 17 + 5)^{2}  }  \\  =  \sqrt{35 ^{2} + ( - 12) {}^{2}  }  \\  =  \sqrt{1225 + 144}  \\  =  \sqrt{1369}  \\  = 37 \: units

Please help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Anon25 [30]

Answer:

A) 40

B) 20

Step-by-step explanation:

By <em>Length · Width · Height</em>

A)  (5) · (4) · (2) = 40

For part B, the length and width are the same, but the depth (height) of the water is only one foot, so we can replace the height value from the first equation with 1.

B) (5) · (4) · (1) = 20
