Answer:

  t = 0.49, 11.91

Step-by-step explanation:

A graphing calculator can show you the answers quickly. The times are 0.49 seconds and 11.91 seconds.

__

We can write the equation as ...

  h = 29

  62t -5t^2 = 29 . . . . . substitute for h

  -5(t^2 -12.4t) = 29

  -5(t^2 -12.4t +6.2^2) = 29 -5(6.2^2) . . . . complete the square

  -5(t -6.2)^2 = -163.2 . . . . . simplify

  t -6.2 = ±√(-163.2/-5) = ±√32.64 . . . . divide by -5, take the square root

  t = 6.2 ±5.71

  t = 0.49, 11.91

The rocket has a height of 29 meters at t=0.49 seconds and t=11.91 seconds.

Answer:

12.86

Step-by-step explanation:

this is rounded to the nearest hundredth

Answer:

Step-by-step explanation:

as Area of triangle is=1/2 base*height

Given

area=70

height=h=8

base lenght=?

put values in above formula for unkown

70=1/2 (8*b)

70=4*b

b=70/4

b=17.5 units

Answer:

3x+2=17 is the equation and x=5

Step-by-step explanation:

Answer:

Equation: 2 + 3x = 17

x = 5

Step-by-step explanation:

2 more than means: 2 +

3 times a number means: 3x

Is 17 means: = 17

Combine them all together:

2 + 3x = 17

Find x:

2 + 3x = 17

3x = 17 - 2

3x = 15

x = 5

Answer:

[tex]\pi[/tex] or 3.1

Step-by-step explanation:

The total area of the circle is [tex]3^2\pi[/tex]. The central angle of the shaded region is 40 degrees so we have to multiply [tex]3^2\pi[/tex] by [tex]\frac{40}{360}[/tex] or [tex]\frac{1}{9}[/tex]. 3 squared is 9 so 9[tex]\pi[/tex] times [tex]\frac{1}{9}[/tex] is just equal to [tex]\pi[/tex]. [tex]\pi[/tex]=3.14159265... rounded to the nearest tenth is 3.1

Answer:

M is (-7,3)

N is (0,1)

I think p is (4,0) but the option isn’t there so I must’ve done something wrong though I can’t find what-

Answer:

1/6 of a cup

Step-by-step explanation:

You're trying to figure out what 1/3 subtract 1/2 is, right?

Well first, convert both of them so they both have the same denominator.

Common Denominator = 6

So, 1/3 is 2/6 and 1/2 is 3/6 and 2/6 plus 3/6 is 5/6. Well, what's left in the cup? 6/6 subtract 5/6 is 1/6

Hope that helps!

hi

-16t²+250 = 75

-16t² = 75 -250

-16t² = -175

  t² = -175 /-16

 t² = 175/16

Here there si two solutions :  t = [tex]\sqrt{175/16}[/tex]   and  t =  - [tex]\sqrt{175/16}[/tex]

However, as time cannot rewind,  we will  keep only positive solution

So t = [tex]\sqrt{175/16}[/tex]

in seconds  it will be  :  3.3 seconds

Answer:

6.

Step-by-step explanation:

6×5 = 30 (product=multiplication)

30+12=42 (increased=addition)

So, the answer is 6.

Answer:

51cm is the answer.

Step-by-step explanation:

a = ?

b = 68cm

c = 85cm

According to the Pythagoras theorem,

a² + b² = c²

a² + 68² = 85²

a² + 4624 = 7225

a² = 7225 - 4624

a² = 2601

a = 51cm

∴ the porch is 51cm tall.

Step-by-step explanation:

To find - a) State the range of X. ​

              b) Write g as a set of ordered pairs.

              ​c) Draw a probability distribution as a histogram. ​

              d) Find ​g(5​), and explain what this number represents. ​

              e) Find μ​, and explain what this number represents.

Proof -

a.)

Range of X = { 0, 1, 2, 3, 4, 5, 6 }

b.)

(0, 7/49), (1, 12/49), (2, 10/49), (3, 8/49), (4, 6/49), (5, 4/49), (6, 2/49)

c.)

The graph is as follows :

d.)

The value of g(5) is 6/49

It represents the probability of the difference of the two spins is 5.

e.)

mean, μ = 2.29

It represents the average value of the spins

Answer:

Step-by-step explanation:

where is the equation

Answer:

A

Step-by-step explanation:

Answer:

1. Yes

2. They could change the 60° angle into a different one.

Step-by-step explanation:

1. Two triangles are the same if they share two side lengths with the same angle between them.

2. Since the triangles are equal if they share two side lengths with the same angle between them, if they changed the angle between 3 and 5, it'd no longer be the same triangle.

Answer:

D)

hope it helps..........

Answer:

D is the correct answer

hope it is helpful to you ☺️☺️☺️

Answer:

(4,1)

Step-by-step explanation:

1: Different x value (bad: 8 units to the left of original point), different y value  (good: on higher horizontal line), d

2: Same x value  (good: same vertical line), different/higher y value  (good: 2 units above original point).

3: Same x value  (good: same vertical line), same y value (bad: same horizontal line, didn’t move higher or lower).

I hope this makes sense lol

Answer:

Slope = 5/3

-------------------

m =  5/3

Answer:

5/3

Step-by-step explanation:

Hello, to find the slope from two given points, you use this formula- y2-y1/x2-x1. In this problem, 9 would be y2, -6 would be y1, 6 would be x2, and -3 would be x1. The equation should look like this:

9-(-6)/6-(-3)

Since both are negatives, you would add it like this:

9+6/6+3= 15/9

Now, you need to simplify this fraction which is 5/3.

Answer:

.156 kg

Step-by-step explanation:

The conversion from grams to kilograms is kg = g/1000

156/1000 = .156

19.532 is greater than 19.522

Step-by-step explanation:

Answers:

38% of 15 = 5.7

29% of 75 = 21.75

4% of 220 = 8.8

No idea what the 1% or 10% method is either. But these answers would be better then to leave the questions blank.
