Answer:

Part 1) The value of y is y=0.8  

Part 2) The value of z is z=0.9

Part 3) The value of x is x=0.5

Step-by-step explanation:

step 1

Find the value of y

we know that

(\frac{225y}{2})\°=90\° ----> given problem (is a right angle)

y=90(2)/225

y=0.8

step 2

Find the value of z

we know that

(50z+13)\°=(80z-14)\° ----> by vertical angles

Solve for z

80z-50z=13+14

30z=27

z=27/30

z=0.9

step 3

Find the value of x

we know that

(44x+125y)\°+(80z-14)\°=180\° ----> by supplementary angles (linear pair)

Substitute the value of y and the value of z and solve for x

(44x+125(0.8))\°+(80(0.9)-14)\°=180\°

(44x+100)\°+(72-14)\°=180\°

44x+158=180

44x=180-158

44x=22

x=0.5

A line has a slope of -2 and contains the point (1,-1). What is the equation of this line
lakkis [162]
The equation would be -2x+1 because since the slope is 2 the slope intercept equation will help you find the y. Y=-2(1)+1

The height (in ft) of an object over time(in seconds) is modeled by the function h(t)=-6t^2+23t+7. How high is the object after
riadik2000 [5.3K]

About 4.1 seconds. How long was the ball in the air? We are told that t represents time in seconds since the ball was thrown, so it started to be 'in the air' at t = 0 To answer the question, then, we need to know the time when it stopped being in the air. We are told that the ball hit the ground. So that's what happened when it stopped being airborne. We need to relate that event to the mathematics we're working with. What can we say about h , the height of the ball when the ball hits the ground? Answer: The height will be 0 when the ball stops being in the air. Now translate this back to the mathematics: The ball is in the air from t = 0 until the time t when h = 0 . Find the time t that makes h = 0 . That means: solve: − 5 t 2 + 20 t + 2 = 0 We can solve this by solving: 5 t 2 − 20 t − 2 = 0 (Either multiply both sides of the equation by − 1 , or add 5 x 2 − 20 x and − 2 to both sides and then re-write it the other way around) That's a quadratic equation, so try to factor first. But don't spend too much time trying to factor, because not every quadratic is easily factorable and that's OK, because we still have the quadratic formula if we need it. We do need it. t = − ( − 20 ) ± √ ( − 20 ) 2 − 4 ( 5 ) ( − 2 ) 2 ( 5 ) = 20 ± √ 440 10 = 20 ± √ 4 ( 110 ) 10 = 20 ± 2 √ 110 10 = 2 ( 10 ± √ 110 ) 2 ( 5 ) = 10 ± √ 110 5 We can see that 10 < √ 110 < 11 . In fact ( 10 + 1 2 ) 2 = 10 2 + 10 + 1 4 = 110.25 Using 10.25 as an approximation for √ 110 , we get : for the solution t = 10 − √ 110 5 we'll get a negative t . That doesn't make sense. The other solution gives t ≈ 10 + 10.25 5 = 20.5 5 = 4.1 seconds. So the ball was in the air from t = 0 until about t = 4.1 . The elapsed time is the difference, 4.1 seconds.

In how many ways can a password be made using 4 letters from the 26 letter English alphabet, if letters cannot be repeated?
elena-14-01-66 [18.8K]

Answer:

I got 358,800

Step-by-step explanation:

First you can choose from 26 letters, then from 25 (because you can't use the same letter) then from 24, and then from 23. You multiply 26 * 25 * 24 * 23 and you get your answer.

I think :)
