Solve the given triangle by finding the missing angle and other side lengths.

Mathematics
1 answer:
Ne4ueva [31]3 years ago
5 0

Answer:

∠ABC= 180° -21° -37° (∠ sum of triangle ABC)

∠ABC= 122°

Using sine rule,

\frac{AB}{sin21°}  =  \frac{200}{sin122°}

AB= 200(sin21°)/sin 122°

AB= 84.5 units (3 s.f.)

\frac{BC}{sin37°}  =  \frac{200}{sin122°}

BC= 200(sin37°)/ sin122°

BC= 142 units (3 s.f.)

F=(9/5) C +32, C=15 Can you show me what a graph looks like?
CaHeK987 [17]

Answer:

Step-by-step explanation:

F=(9/5) C +32 has the form of the equation of a straight line:  y = mx + b, where m is the slope and b is the y-intercept.  By comparing these two equations we see that the slope, m, is (9/5) and the y-intercept is 32 (or (0, 32)).

To graph this, first locate the y-intercept (0, 32); put a dark dot there.  Since the slope is 32, or 32/1, move your pencil point 1 unit to the right, from (0, 32) to (1, 32), and then from (1, 32) move y our pencil point 32 units upward.  Plot another dark dot there and then draw a straight line through these two points.

We can evaluate the given function F=(9/5) C +32 at C = 15 by replacing C in the formula with 15:  F = (9/5)(15) + 32, or F = 59.

Select all of the statements that are true for the given parabola.
Masja [62]

Answer:

A and B are true

Step-by-step explanation:

The minimum is the turning point on the graph and occurs at (1, - 2)

The x- intercepts are where the graph crosses the x- axis , that is at

x = - 1 and x = 3 or in coordinate form (- 1, 0 ) and (3, 0 )

The equation of the axis of symmetry is a vertical line passing through (1, - 2)

with equation x = 1

The true statements are A and B

Help I’ll give out brainliest thank you
djyliett [7]

Answer:

37 hours

Step-by-step explanation:

to find out how many hours it will take the ship to get to the bahamas, we must take the distance that needs to be traveled and divide it by the distance traveled every hour (m/h)

859 / 23 = 37.3478261

now, rounded to the nearest hour, that would be 37 hours
