Let's plug in 2 for t and solve and h:
h(t) = -16t^2 + 541
h(2) = -16(2^2) + 541
h(2) = -16*4 + 541
h(2) = -64 + 541
h(2) = 477 feet
Answer is b) 477 feet
Answer:
B
Step-by-step explanation:
Answer:
36 units
Step-by-step explanation:
there is 12 units at is base and 9 as its height
you have to use the Pythagorean theorem to find the hypotenuse
c= √(a^2+b^2)( be being 12 and a 9)
plug it in and get c=√(81+144)=√225=15
perimeter is a+b+c
now that we have c do 12+15+9
=36
The answer would be be the same (285.429)
Answer to the first problem is 3 3/9
Reasoning:
To do these equations, you must change the mixed numbers into just fractions. I will do the first problem :)
2 divided by 3 2/3.
The first step in solving this equation is changing 3 2/3 back into a fraction.
To do this, do the denominator (3) times the whole number (also 3) and then add the numerator (2). 3 x 3 = 9. 9 is now your numerator and 3 is your denominator. 9/3
After this you want to put 10/1 MULTIPLIED by 3/9 (when dividing fractions you must flip the second fraction AND THEN MULTIPLY)
So 10/1 MULTIPLIED by 3/9 = 30/9
It then wants us to simply our answer. To do this, divide 30/9 by 9. You’ll get 3 3/9 as your answer for question 1!
