What's the x-intercept for number 26?
Lunna [17]
It gives function: h = -16t^2 + 40
water is when height is 0 so solve for 0= -16t^2 + 40
subtract 40 from both sides: -40 = -16t^2
divide by -16: -40/-16 = t^2
simplify: 5/2 = t^2
square root both sides: 1.58 = t

The area of a garden is 8 3/4 square yards. If the lenght is 1 1/4 yards , what is the length?​
andrezito [222]

Answer:

The Missing Length = 7

Step-by-step explanation:

Equation: side length x side length = area

  • This means that if you divide the area by one of the side lengths, you'll find the other

1.  Convert the numbers into decimals

  • 8 3/4 -  8.75 (area)
  • 1 1/4  = 1.25 (side length)

2. Divide the <u>area</u> by the <u>side length</u>

  • 8.75 ÷ 1.25 = <u>7</u>

<u></u>

<u>7</u> is the answer.

Help ? Plz forgot the steps (3z+9)(z-4)
Dafna11 [192]
It's a binomial times a binomial, so you FOIL
First multiply the First numbers
3z*z = 3z(^2)
Then multiply Outers:
3z* -4  = -12z 
Nest, Inners:
9*z = 9z
Finally, the Lasts: 
-4*9 = -36
Then, throw it all together in descending order, starting with the variable of highest degree to lowest:
3z^2 - 12z + 9z - 36
Last of all, simplify coefficients with like terms and you're good to go:
3z^2 - 3z - 36
Hope this helps!
