Zip and zoom just build a toy rocket and set it up on a platform for feet high. The kit claims the velocity of the rock it will be about 120 ft./s. The equation to represent the height in feet in terms of time (second) is H=-16t+120t+4.
A. What is the starting height of the rocket?
B. Zip is wondering what the height of the rock it will be after two seconds

Answers

Answer 1

the starting high would be at 120 ft but after 2 seconds it should be around 150-160 ft

What is the Surface Area of this figure?

Answers

Answer:

[tex]174 cm^{2}[/tex]

Step-by-step explanation:

There are two triangles and two rectangles in the figure.

To find the area of the triangles:

6 x 9 = [tex]54cm^{2}[/tex]

To find the area of the rectangles:

9 x 8 = [tex]72cm^{2}[/tex]

6 x 8 = [tex]48cm^{2}[/tex]

Add all of this together for your answer:

54 + 72 + 48 = [tex]174cm^{2}[/tex]

Jackie has one sister. Jackie's sister is 4 years older than her. The girls' ages add up to 28. Write an equation to solve for Jackie's age. *

Answers

Answer:

Jackie's age = 12 years and Her sister's age = 16 years

Step-by-step explanation:

Let the age of Jackie be x.

Her sister's age = (x+4)

The sum of ages = 28

ATQ,

x+x+4 = 28

2x+4 = 28

2x = 24

x = 12

Jackie's age = 12 years

Her sister's age = (12+4) = 16 years

Hence, this is the requiredsolution.

In the figure below, $AB=75,$ $AC=70,$ and $BY=60$. Compute $CX$.

Answers

Compute the area A of ∆ABC.

• Take AB to be the base and CX (which is an altitude of ∆ABC) to be the height. Then the area is

A = 1/2 • AB • CX = 1/2 • 75 • CX

• Now take AC to be the base and BY (also an altitude) to be the height. Then

A = 1/2 • AC • BY = 1/2 • 70 • 60 = 2100

The areas must be equal, so we have

2100 = 1/2 • 75 • CX   →   CX = 4200/75 = 56

Angle PQS is found by 180-80=100

180- 100-30=50

Answer:

50 degrees

Step-by-step explanation:

<PQS +<RQS = 180°(sum of angles in a straight line)

#+80=180

#=180-80

#=100°

30° + x + # = 180°(sum of angles in a Δ)

30+x+100=180

x+130=180

x=180-130
