Answer:

Equation: 1.5s + 20 = 200

How long it will take for Samantha to finish a 200 meter race: 120 seconds

Step-by-step explanation:

The problem says Samantha walks at a rate of 1.5 meters per second. If we let "s" represent seconds, then we can write this as 1.5s. Since she gets a 20 meter head start, you can then write the equation as 1.5s + 20. Finally, its says use this equation to find how long it would take to finish a 200 meter race. So you set the previous equation equal to 200. Or 1.5s + 20 = 200.

To solve for "s" and find how long it would take to finish a 200 meter race, you first subtract 20 from each side. You should be left with 1.5s = 180. Then divide by 1.5. 180/1.5 equals 120. So it will take Samantha 120 seconds to finish the 200 meter race.

Using the definitions of odd and even functions, explain why y= sin x+1 is neither odd nor even.

Answer:

Step-by-step explanation:

The graph is symmetric with respect to the origin therefore it is on odd function. The graph is symmetric to the y- axis therefore it is an even function. The majority of functions are neither odd nor even, however, sine and tangent are odd functions and cosine is an even function.

John leaves his home. He travels 5 blocks south and three blocks west. As the crow flies, how far is John from his home?

riadik2000 [5.3K]

Answer:

5.83 blocks away from his home

Step-by-step explanation:

If he travels 5 blocks south and 3 blocks west, the distance from his house considered along with the distances travelled gives a right angled triangle whose opposite side and adjacent sides are the distances travelled north and west.

The distance from his house after moving 3 blocks west is the hypotenuse side. As such, the distance may be computed using Pythagoras' theorem. Let the distance from his house be G

G^2 = 5^2 + 3^2

G^2 = 25 + 9

= 34

G = √34

=5.83

John is 5.83 blocks away from his home

PLEASE ANSWER!!!!!! REALLY IMPORTANT

faust18 [17]

Answer-

The height of the prism is 6 units

Solution-

As the base of the prism is a hexagon consisting of 2 congruent isosceles trapezoids.

So,

$V_{Prism}=Area_{Base}\times Height$

And,

$Area_{Base}=2\times \text{Area of the trapezoid}$

Also,

$\text{Area of the trapezoid}=\dfrac{1}{2}\times \text{Height}\times (\text{Sum of two parallel lines})$

$=\dfrac{1}{2}\times 3\times (5+8)\\\\=\dfrac{39}{2}$

Putting all the values,

$V_{Prism}=2\times \dfrac{39}{2}\times Height=39\times Height$

As the volume is given, so

$\Rightarrow 39\times Height=234$

$\Rightarrow Height=\dfrac{234}{39}=6$
