Answer: First One's order = 1.7%, 17/100, 17
Second One's order is 12.5%, 1.25, 1 2/5
Step-by-step explanation:
to change the percent into decimal you move the decimal to the left 2 spots. (ex. 5%=.005)
The time that the ball is in the air if the player lets the ball drop is 2.145 sec
What is a quadratic equation?
A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax²+ bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.
-16t²+32t+5
by comparing this equation to the standard form of the quadratic equation we get
a=-16 b=32 c=5
the time (t) needed for the ball to reach its maximum height using the axis of symmetry formula (x = -b/2a) for a parabola:
the time at which the ball reaches the maximum height using the axis of symmetry formula is (x=-b/2a)
t = -32/2×-16
t=1sec
by putting h(t) to zero and determining the time (t) when the ball hits the ground:
-16t²+32t+5=0
-16(t²+2t+5/16)=0
t²-2t-5/16=0
(t)²-2×1×t+(1)²-5/16=1
(t-1)²=21/16
t-1=√21/√16
t=1+4.58/4
t=1+1.145
t=2.245sec

the answer is |x| 5
Step-by-step explanation:
unless there is a number for x the number can't be solved
Answer:
Step-by-step explanation:
You have to write in y = mx + c form
3x - 5y = 25
-5y = -3x - 25
Factorisation is basically where you have to find everything in common between 2, 3 or 4 terms.
In factorization, you take out the like-terms. eg.
12x-6y
6(2x-y)
We have to find the HCF of 6 and 12 which is 6.
Here, the 6 is common (goes outside the bracket) and the other numbers (which are in the bracket) are uncommon.
Always remember in factorisation that:
+ and + = –
– and – = +
– and + = –
+ and – = –
