The measures of the three angles in a tri-<br>angle are in the ratio 1:2:3.​
Zepler [3.9K]

Answer:

30,60,90

Step-by-step explanation:

triangle are in the ratio 1:2:3.​

So

Angles=X,2x,3x

X+2x+3x=180

6x=180

X=180/6

X=30

So angles are 30,60,90

A golfer hits the golf ball. The quadratic function y = −16x^2 + 80x gives the time x seconds when the golf ball is at height 0
svetlana [45]
You need to calculate the two zeros of the function. The first zero is the "start", the second zero is the "end" of the trajectory.

Well...

0 = x(-16x+80)

First zero is x=0 (the start of trajectory)

Second zero:

-16x+80=0.... x=5! (The end of the trajectory!)

Good luck!

Find the equation of a line that is parallel to line g that contains (P, Q).
Fofino [41]

Correct option:

\boxed{x-y=P-Q}

<h2>Explanation:</h2>

Given that the line we are looking for is parallel to g, then the slope of that line and g is the same, therefore:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ (x_{1},y_{1})=(-3,2) \\ \\ (x_{2},y_{2})=(0,5) \\ \\ \\ m=\frac{5-2}{0-(-3)}=1

So we can write the point-slope form of the equation of the line as follows:

y-y_{0}=m(x-x_{0}) \\ \\ (x_{0},y_{0})=(P,Q) \\ \\ \\ y-Q=1(x-P) \\ \\ y-Q=x-P \\ \\ \\ Arranging: \\ \\ P-Q=x-y \\ \\ \boxed{x-y=P-Q}

What is the solution to this equation?
ZanzabumX [31]

Answer:

x = 21

Step-by-step explanation:

(x+6)^1/3 - 5= -2

add 5 to both sides of the equation:

(x+6)^1/3 = 3

cube both sides of the equation:

x + 6 = 27

subtract 6 from each side:

4 = -7s - 10<br><br> how do you get -2? please show your work
andreyandreev [35.5K]
First u add ten to both sides to cancel out. Now you have 14=-7s. Since you are trying to do the opposite operation, you divide by -7 on each Sides. Now you have -2=s. Hope this helped
