Answer:

49m/s

59.07 m/s

Step-by-step explanation:

Given that :

Distance (s) = 178 m

Acceleration due to gravity (a) = g(downward) = 9.8m/s²

Velocity (V) after 5 seconds ;

The initial velocity (u) = 0

Using the relation :

v = u + at

Where ; t = Time = 5 seconds ; a = 9.8m/s²

v = 0 + 9.8(5)

v = 0 + 49

V = 49 m/s

Hence, velocity after 5 seconds = 49m/s

b) How fast is the ball traveling when it hits the ground?

V² = u² + 2as

Where s = height = 178m

V² = 0 + 2(9.8)(178)

V² = 0 + 3488.8

V² = 3488.8

V = √3488.8

V = 59.07 m/s

Answer:

Twenty percent of $47.83 is equal to $14.66

If you did 20% of 47.83, that would equal 9.566. So, now you need to take the 5, which is equal to 500 cents, and turn it into 5 dollars. (One hundred cents is a dollar so 500 cents , is 5 dollars.) now it’s 9 + 5. Easy, it’s 14. Now add back the 66, and it’s 14.66 dollars. So the answer is...

14.66

y = -4/3x + 6

Step-by-step explanation:

1. 3y - 4x + 3y = 18 - 3y

2. 4x = -3y + 18

3. 18 - 4x = -3y + 18 - 18

4. -3/ -3y = 4x - 18 /3

5. y = -4/3x + 6

Answer:

[tex]t=4820 y[/tex]

Step-by-step explanation:

a) The half-life equation is given by:

[tex]t_{1/2}=\frac{ln(2)}{k}[/tex]

b) Using the decay equation we have:

[tex]Q(t)=15e^{-0.0001438t}[/tex]

we need to find t when [tex]Q(t)=\frac{Q_{0}}{2}[/tex]

[tex]7.5=15e^{-0.0001438t}[/tex]

[tex]0.5=e^{-0.0001438t}[/tex]

[tex]ln(0.5)=-0.0001438t[/tex]

[tex]t=\frac{ln(0.5)}{-0.0001438}[/tex]

[tex]t=4820 y[/tex]

Therefore, it will take 4820 years to decay to half the original amount.

Step-by-step explanation:

Answer:

ST = 16

Step-by-step explanation:

The similar triangles are given as triangle PQR similar to triangle STU.

That makes sides PQ and ST corresponding sides. It also makes sides PR and SU corresponding sides. The ratios of the lengths of corresponding sides of similar triangles are equal.

[tex] \dfrac{ST}{PQ} = \dfrac{SU}{PR} [/tex]

[tex] \dfrac{5x + 1}{36} = \dfrac{11x - 5}{63} [/tex]

Multiply both sides by 9.

[tex] \dfrac{5x + 1}{4} = \dfrac{11x - 5}{7} [/tex]

Cross multiply.

[tex] 7(5x + 1) = 4(11x - 5) [/tex]

Distribute on both sides.

35x + 7 = 44x - 20

Subtract 44x from both sides.

-9x + 7 = -20

Subtract 7 from both sides.

-9x = -27

Divide both sides by -9.

x = 3

ST = 5x + 1 = 5(3) + 1 = 15 + 1 = 16

Answer: ST = 16

Answer: A. because it is the only one that makes sense, the unit rate is where the second quantity is one unit: etc. 1 minute=60 seconds1 hour=60 minutes (or) 3600 seconds1 day=24 hours (or) 1440 minutes.

Answer: They both are located at (2,3)

Step-by-step explanation:

The sign that A and C are related is that they both have the same distance from the y axis.

a pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

For example (5,3) here 5 will be for the x and 3 will be for the y.

Another example is (9,0) here 9 is for x and 0 is for y.

Given that the coordinates A and C how are related now as we can see that both A and C are the same amount of distance by the y-axis.

This also can be seen by the coordination of A and C.

Answer:

vertical angles theorem

Corresponding angles are two or more angles that have similar properties. Thus they have equal measures.

The required prove is given in the explanation below:

Considering the given diagram, it can be observed that:

<1 ≅ <3 and <2 ≅ <4     (vertically opposite angle theorem)

Also,

<5 ≅ < 7 and <6 ≅ <8    (vertically opposite angle theorem)

m ⊥ n and a ⊥ b             (given)

Thus,

<1 + <2 + <3 + <4 = [tex]360^{o}[/tex] (sum of angles at a point)

Also,

<5 + <6 + <7 + <8 = [tex]360^{o}[/tex]  (sum of angles at a point)

Therefore,

<1 ≅ <7                             (corresponding exterior angle property)

Therefore by corresponding exterior angle theorem, <1 ≅ <7.
