Answer:
30 feet
Step-by-step explanation:
Hello!
Half an hour is 30 minutes, so that means we are asked to find h(30).
Solve for h(30):
- h(30) = 150 - 4(30)
Substitute 30 for t - h(30) = 150 - 120 Simplify
- h(30) = 30
The person would be 30 feet above the ground in half an hour.
Hey erika and the answer is 25 minutes
Answer: 5
Explication: Do PEMDAS first solve the parenthesis which is 6x19= 114 then add the 25 which equals 139. Now slice the exponent 6^2=36 then multiply by 4 which equals 144. Subtract 144-139 and you get 5
Angle C is 4 square root 11 or in decimals 13.266
Answer:
x=5 twice
Step-by-step explanation:
x^2-10x+25=0
multiply the coefficient of x^2 and the last term
1X25=25
find two numbers you can multiply to get 25 and add to get -10
-5 + (-5)=-10 the middle term
replace -10x with -5x -5x and solve the equation
x^2-5x-5x+25=0
factorise by grouping
x(x-5)-5(x-5)=0
(x-5)(x-5)=0
Either x-5=0,x=5 or x-5=0,x=5
Therefore x=5 twice.
