Answer:

The cities are actually 190 km apart.

Step-by-step explanation:

Consider the provided information.

It is given that a map scale is 1 cm : 50 km.

We need to find the distance between the two cities if they are 3.8 cm apart.

To find the actual distance between the two cities using the map, multiply each side of the relationship by 3.8

3.8 × 1 cm : 3.8 × 50 km

3.8 cm : 190 km

The cities are actually 190 km apart.

It would be 190 km because you do 5 x 3 to get 15 add a 0 at the end of it. Than at 40 because .8 of 150 is 40. Then 150+40= 190

Determine o período e o conjunto imagem, construindo o gráfico de um período completo para cada função dada.a) por f(x) = 1+ 4 s

nataly862011 [7]

Answer:

The given functions are

$f(x)=1+4sinx$

$f(x)=2sin(x-3)$

The sine function has a standard period of $2 \pi$ by definition. However, this might change if we use a factor as coefficient of the x-varible, but in this case we don't have that.

Therefore, the period of both trigonometric functions is $2 \pi$ .

Now, the images of each function is the y-variable set values that defines each function.

So, the function $f(x)=1+4sinx$ has an image defined by the set $[-3,5]$ . It's impotant to notice that the range of a standard function is [-1,1], however, in this case, the function was shifted 1 unit up and it was streched by a factor of 4, that's why the standard image changes to $[-3,5]$ .

About the second function $f(x)=2sin(x-3)$ , the image set is $[-2,2]$ , because the function was streched by a factor of 2.

Additionally, the image attached shows the graph of the given functions.

Find the value of "k", given that one solution of the equation x2-kx+21=0 is 3

Ilia_Sergeevich [38]

Plug in 3 for x and solve for k.
(3)^2-3k+21=0
3k=9+21
3k=30
k=10

Jason tossed a fair coin 3 times. What is the probability of getting a head and two tails in any order 1.3/8 2.4/8 3.5/8 4.6/8 p

ladessa [460]

Answer:

1. 3/8

Step-by-step explanation:

Total tossed times = 3

Total Possibilities = 8

Possibilities = (Head, Head, Head), (Tails,Tail,Tails), (Head,Head,Tails), (Head,Tail,Head), (Tails,Head,Head), (Head,Tail,Tail), (Tail,Tail,Head), (Tail,Head,Tail)

Number of options with a head and two tails = 3

So, Probability = Number of correct options ÷ Number of total possibilities

= 3 ÷ 8 or 3/8
