Suppose you start at the origin, move along the x-axis a distance of 4 units in the positive direction, and then move downward a

(4, -3).

Note that moving downward from the origin locates you in a negative y-cooirdinate; -3 in this case.

Answer:

4 seconds to reach 200 feet

Step-by-step explanation:

You can use Desmos (graphing calculator) then plug in the equation and you will find the x-values are 7.188 and 0- the origin.

Divide 7.188 by 2 (this is also solving for the midpoint/axis of symmetry) and you get 3.594

Round 3.594 to the nearest second which would be 4 seconds.

Hope that helps and have a great day!

Solve the triangle A=21 C=105 c=5

gregori [183]

Answer:

Granted that uppercase letters are the angles measurements and lowercase letters are the side lengths. I also was unable to round as I don't know to what decimal you need to round to.

First to find the measure of angle B, we must subtract A and C from 180

$180-21-105=54$

B=54

Next, we can use the law of sines in order to find the measures of a and b

As a reminder, The law of sines is

$\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

First, lets solve for b

$\frac{b}{sin54}=\frac{5}{sin105} \\\\b=\frac{(5)sin54}{sin105}\\\\b=4.187780119$

Next lets solve for a

$\frac{a}{sin21}=\frac{5}{sin105} \\\\a=\frac{(5)sin21}{sin105}\\\\a=1.85504901$
