Answer:
It is A
that fancy sign means the square root, not division.
B is untrue as well
The expression for the height is given in quadratic expression form
Ax² + Bx + C
Where A, B, and C are constant
To find the x-coordinate when the graph reaches maximum/minimum, we use the formula
x = -B ÷ 2A
We have
h = -16t² + 112t + 30
The value for A = -16, B = 112, and C = 30
Substitute these into x = -B ÷ 2A we have
t = -112 ÷ (2×-16) = 3.5
The maximum height is reached when t = 3.5 sec
The height when t = 3.5 sec is given
h = -16(3.5)² + 112(3.5) + 30 = 226 feet
Answer:
7.72, 7.9, 7.93
Step-by-step explanation:
Since all the number's ones place begins with 7, you would want to use the tenth's place to solve this problem.
You can see that there is 7, 9, and 9 in the tenths place and that already makes 7 the least number.
7.9 is equivalent to 7.90 so we can see that 7.90 is less than 7.93. That makes 7.93 the greatest number and 7.72 the least.
7.72<7.9<7.93
Answer:
A. x = 3, y = -3
B. a = -2, b = 5
C. try your best ill see u later
Step-by-step explanation:
Okay I'mma state some stuff first 3^a + 3^b = 3^(a+b)
and 3^a/3^b = 3^(a-b)
So first equation 3^3*3^-3=3^0
So second equation 3^3/3^-2 = 3^5
So third equation I dont really know the rule but I'mm just plug in a random number for g, like 2, then solve the thing like a normal equation.
So 3^-3 x f^-3 = 12^2 = 144, f^-3 = 144/(3^-3 or 1/27) = 144 x 27 = 3888
so f^-3 = 3888, f = well its an imaginary number according to calculator so u try your best on the last one
Answer:
To turn this equation into a fraction, convert both numbers into a fraction when multiplying.
Step-by-step explanation:
-7 = -7/1 or 7/-1
7/-1 * -3/5 * 15/7
- Multiply numerators and then multiply denominators and then simplify
(7*-3* 15)= -315
(-1*5*7) =-35
-315/-35=9
