What is the value of x y and z below?

Answers

Answer 1

Answer:

Answer: Y=76 X=104 Z=104

Step-by-step explanation:

The degree 76 and y are both equal so you add it and it is 152.

Then subtract 360-152 to get 208 and since X and Z are equal you divide and get 104.

Please nobody falsely answer this im very low on points i just need help please!!

Answers

You should just have to multiply each coordinate by the scale factor, giving
F’ (1.5,1.25)
G’ (2.5,0.25)
H’ (0.5,0.25)

Answer:

The first option

Step-by-step explanation:

The coordinates of each point divided by 4 matched up with the ones on that answer so it's the first one. it's proportional so I think that's it.

Solve this problem using estimation.Melissa bought 18 cupcakes and 2 gallons of fruit punch for her Valentine party. If the cupcakes cost $.33 each and the punch costs $2.78 a gallon, estimate the cost of the cupcakes.

Answers

If she bought 18 cupcakes at $0.33 each, and 2 gallons of punch at $2.78 each, then Melissa have spent $11.50 overall for the cupcakes.

A baseball player hits a ball toward the outfield. The height h of the ball in feet is modeled by h(t) = -16t2 + 22t + 3, where t is the time in seconds. If no one catches the ball, how long will it stay in the air? (Round to the nearest tenth of a second and enter only the number.)HINTS:
• When the ball hits the ground, its height is zero, so you are looking for one of the zeros of the quadratic equation.
• Though you could use several different methods, the easiest way to solve this particular equation is the quadratic formula (provided here). Take the a, b, and c values from the function in the question above.
• When you solve the quadratic for the zeros, you will have two answers. One of the answers will not make sense for a baseball hit into the outfield. The one that does make sense will be the correct answer.

Answers

Solving this equation for the roots, we find that the roots are -1/8 and 3/2. Assuming that at t=0 is when the player hits the ball, t=0 and t=3/2 is the amount of time in the air. Therefore, the ball spent 3/2 seconds in the air, or 1.5 seconds.

Final answer:

The time that the baseball stays in the air is determined by setting h(t), the height, to 0 and solving for t (time) using the quadratic formula; the positive answer represents the time in seconds that the ball stays in the air.

Explanation:

In order to find how long the baseball will stay in the air, we need to solve for the value of t (time) when the height h(t) is equal to 0. This is given by the formula h(t) = -16t2 + 22t + 3. We equate this to zero and solve for t using the quadratic formula: t = [-b ± sqrt(b2 - 4ac)] / (2a).

Here, a = -16, b = 22, and c = 3. Substituting these values into the formula gives two solutions for t. However, we reject the negative solution since time cannot be negative. Therefore, the positive solution gives the amount of time (rounded to the nearest tenth of a second) the baseball stays in the air before it hits the ground.
