1. A model rocket was launched from a podium 5 meters above ground at a
initial velocity of 98 m/s. The function that models height (in meters) with
respect to time (in seconds) is h(t) = 5 + 98t – 4.9t2.
Part A: Complete the table below.

Use a calculator to find both roots.
t
is approximately
−
3.86
or
3.24
.
Consider the roots logically. One solution,
−
3.86
, cannot be the time because it is a negative number. The other solution,
3.24
seconds, must be when the ball hits the ground.
Answer
The ball hits the ground approximately

In a fruit punch you mix 150 ml of lemonade with 250 ml of fruit juice. Write the ratio of the volume of lemonade to the volume of fruit juice. Give your ratio in its simplest form.
Answers
Answer:the ratio of the volume of lemonade to the volume of fruit juice in simplest form = 3:5
Step-by-step explanation:
Volume of lemonade in the mixture = 150ml
Volume of fruit juice in the mixture = 250ml
Ratio of the volume of lemonade to the volume of fruit juice= 150ml: 250ml
and reducing to the simplest form , we have
150:250
dividing both by 10 gives
15:25
dividing both by 5 gives
3:5
Therefore the ratio of the volume of lemonade to the volume of fruit juice in simplest form = 3:5

Answer:
The answer is A) There are no proportional relationship
Step-by-step explanation:
The green line does not go through the origin and it is curved. This is not a proportional relationship.
Problems: It does not go through 0,0 and it is curved.
----------------------------------------------------------------------------------------------------------------
The blue line may go through the origin but it is curved. This is not a proportional relationship.
Problem: It is curved.
----------------------------------------------------------------------------------------------------------------
The purple line does not go through the origin. This is not a proportional relationship.
Problem: It does not go through 0,0
----------------------------------------------------------------------------------------------------------------
Conclusion: Since the green, blue, and purple line are not proportional, this means zero lines are proportional.

Answer:
C
Step-by-step explanation:
slope=walking speed /%
negative slope
so that rules out a and d
and you can see that as the percent increases the speed decreases.

Across what line of reflection was the angle reflected in the coordinate plane below?
Answers
Answer:
Let us revise the reflection
If point (x , y) reflected across the x-axis, then its image is (x , -y)
If point (x , y) reflected across the y-axis, then its image is (-x , y)
If point (x , y) reflected across the line y = x, then its image is (y , x)
If point (x , y) reflected across the line y = -x, then its image is (-y , -x)
∵ Point A (-5 , 8) is reflected across the line y = x
∵ If point (x , y) reflected across the line y = x , then its image is (y , x)
∵ x = -5 and y = 8
- Switch x and y
∴ The image of point A is A' = (8 , -5)

In triangle EFG, the measure of angle E is 97 and the
measure of angle Fis 15° What is the measure of angle G?
Answers
Every triangle’s angle measures add up to 180. So you add 97 and 15 which equals 112, and then you subtract 112 from 180. 180-112= 68 so that is your final answer. I hope this helps:)
By using triangle sum theorem in triangle EFG, measure of the unknown angle ∠G will be 68°.
Calculations for the measure of angles in a triangle:
Measures of the angles in a triangle has been given as,
m∠E = 97°
m∠F = 15°
By triangle sum theorem,
m∠E + m∠F + m∠G = 180° (Sum of interior angles of a triangle is 180°)
97° + 15° + m∠G = 180°
m∠G = 180 - 112
m∠G = 68°
Therefore, measure of the third angle (∠G) of ΔEFG will be 68°.
