Answer:

Step-by-step explanation:

Solving:

Use the formula h = -16t^2 +vt +s

What we know:

v = 64 feet per second (initial velocity)

s = 80 foot (initial height)

h = ?

t ?

h = -16t^2 + 64t + 80

I know I should be asking in detail, are you allowed to use the quadratic formula or solve it by factoring it out?

What is the number in standard form?<br><br> 4.9×10^8
belka [17]

In order to get the answer to this question you have to remember that if the exponent is positive you need to move to the right, and if the exponent is negative you got to move to the left.

  • 4.9\times10^8
  • Positive so move to the right 8 times....
  • 4.9\times10^8 = 490000000.
  • = 490000000.

Therefore the answer is "490000000."

Hope this helps!

A 4 meter ladder leans against a house forming a
Ket [755]

Answer:

2.meters

Step-by-step explanation:

Lenght of ladder = 4 m

θ = 30°

To obtain h;

Using Pythagoras rule :

Sinθ = opposite / hypotenus

Hypotenus = 4 ; opposite = h

Sin 30 = h / 4

0.5 = h / 4

h = 0.5 * 4

h = 2 m

Hence, distance between th efoot of ladder and the base of the wall is 2 m

*repost since nobody answered* how would i answer this?
pshichka [43]

Answer:

b is not a function

Step-by-step explanation:

To be a function there must be a one to one correspondence.

Each x must only go to one y

b has an x that goes to two different y's

1 goes to 5 and 13.  That makes it a relation not a function
