Find the value of sin210° How do you find this?

1 answer:

8 0

Find the value using the definition of sine.

sine (210 degrees ) = opp/hyp

Substitute the values into the definition.

sin (210 degrees ) = -1/2 / 1

Simplify the result.

Multiply the numerator by the reciprocal of the denominator.

-1/2 .1

Multiply -1 by 1 to get -1

-1/2

frutty [35]

Answer:

Step-by-step explanation:

Mary bought 1 fish, Ari bought 20 fish, Rodney bought 4 fish, Carissa bought 3 fish, Jacob bought 4 fish, Jack bought 1 fish, Jaleesa bought 2 fish, Andrea bought 5 fish, Geoff bought 1 fish, Becky bought 4 fish, Molly bought 1 fish, David bought 2 fish, Gina bought 7 fish, James bought 1 fish, Anessa bought 2 fish, Ted bought 1 fish, Sean bought 2 fish, Kerri bought 11 fish, Sammy bought 3 fish, Jameson bought 2 fish, Theresa bought 2 fish, Luz bought 2 fish, Tracy bought 4 fish, Jackson bought 5 fish, and Celia bought 7 fish.

Rewrite the numbers

1,20,4,3,4,1,2,5,1,4,1,2,7,1,2,1,2,11,3,2,2,2,4,5,7

a: I can't draw a line plot, but I can tell you some tips.

Set the x as the different numbers that appear in the set

Set the y as the frequency of each number.

b: 2 fish has the highest frequency.

c: Add the terms. 97 is the total fish been bought

d: The outlier is 20 bought fish

a: When making the stem and leaf plot, do it in this format

1| 7,4,3,5,8,4

and so on.

b: the heaviest puppy is 25 and the lightest is 13

so the range is 12

c: 4 puppies weighed at least 20 pounds

3. There are no following values, but for this I would make a box and whisker plot.

4. There is no histogram but it should be relatively easy if you know which aspect of the graph to use.

a: Find the frequency of each bar and add them.

b: the largest number of boxes is the interval that is the largest

c: Use the graph to find it

d: I can't do this without the graph.

José left Westcliffe on his bicycle riding at an average rate of 8 miles per hour five hours before his father left by automobil

Serga [27]

Answer:

48 miles per hour

Step-by-step explanation:

José left Westcliffe on his bicycle riding at an average rate of 8 miles per hour five hours before his father left by automobile. The father overtook José in exactly one hour. This means Jose was riding

5 hours + 1 hour = 6 hours.

Use formula

$D=r\cdot t,$

where

D = distance

r = rate

t = time

In Jose's case,

D = unknown

r = 8 miles per hour

t = 6 hours

Hence,

$D=8\cdot 6=48\ miles$

In Jose's father case,

D = 48 miles

r = unknown

t = 1 hour (father overtook José in exactly one hour)

Hence,

$48=r\cdot 1\\ \\r=48\ miles \ per \ hour$

If you wanted to vertically stretch the graph of F(x) = |x| by five units, what would the equation of the new function, G(x), be

zheka24 [161]

Solution:

The Preimage function is , F(x)=|x|

Consider a point (a,b) on the function, F(x)=|x|. it means

b=|a|-----(1) satisfies the function.

Now the function F(x)=|x| is vertically stretched by 5 units.It means

x=a , y= b+5

x=a, b=y-5

So, putting the value of a and b in equation (1).

y-5=|x|

y= |x| + 5 is vertical stretch of y= |x| by 5 units.
