Answer:
Time taken by the ball to reach the maximum height = 5/32 seconds
Step-by-step explanation:
To find the time at which maximum height is reached , we will differentiate the given equation with respect to t
[tex]\frac{db_{(t)}}{dt} = -32t + 5 = 0\\t = \frac{5}{32} \\[/tex]
Substituting this value of t in formula of b(t), we get
[tex]-16 * (\frac{5}{32})^2 + 5 * \frac{5}{32} + 15 \\= 15.390[/tex]

The length of a side of a square is (6x + 6) km. Find the area of the square in terms of the variable x.
Answer:
36(x + 1)^2 = 0 or 36x^2 + 72x + 36
Step-by-step explanation:
s^2 = area of a square
(6x + 6) (6x + 6)
6x*6x = 36x^2
6x*6 = 36x
6*6x = 36x
6*6 = 36
36x^2 + 36x + 36x + 36
36x^2 + 72x + 36
36(x + 1)^2 = 0

Find the y-intercept of each line defined below and compare their values
Answer:
They are 8 units apart, and the y-intercept of line A is above the x-axis by 6 units, and line B is below the x-axis by 2 units
Step-by-step explanation:
Remember your y-intercept has an x value of zero, so line B has a y intercept of (0,-2)
now let's find b in the original equation so
y - 8 = -2x - 2 so y = -2x -2 + 8, so y = -2x + 6
So line A has a y-intercept of (0,6)
They are 8 units apart, and the y-intercept of line A is above the x-axis by 6 units, and line B is below the x-axis by 2 units

Which of the following is the complete list of roots for the polynomial function fx) =
-(x2+
6x+8)(x2+6x+13)
Fast plz
The complete list of roots for the polynomial function in the image is -2, -4, -3 + 2i, -3 - 2i.The polynomial function is given by
[tex]f(x) = x^4 + 5x^3 - 22x^2 - 58x + 24[/tex]
We can find the roots of this polynomial by factoring it. The factors of the polynomial are:
[tex](x + 2)(x - 2)(x + 3 + 2i)(x + 3 - 2i)[/tex]
The x numbers that bring the polynomial's roots to 0 are known as its roots. We can see that the polynomial has a value of 0 for the following values of x: -2, 2, -3 + 2i, and -3 - 2i. Therefore, the polynomial's full list of roots is -2, -4, -3 + 2i, and -3 - 2i.
The steps for locating the polynomial's roots are described below:
By grouping, we can factor the polynomial.
The polynomial's factors are (x + 2), (x -2), (x + 3 + 2i), and (x + 3 - 2i).
The x numbers that bring the polynomial's roots to 0 are known as its roots.
We can see that the polynomial has a value of 0 for the following values of x: -2, 2, -3 + 2i, and -3 - 2i.
Therefore, the polynomial's full list of roots is -2, -4, -3 + 2i, and -3 - 2i.

E is the midpoint of BC
So, BE = 20/2 = 10 cm
ΔABE is a right angled triangle. So, to find AE, we can use Pythagorean theorem.
hypotenuse² = base² + altitude²
AE² = BE² + AB²
= 10² + 20²
= 100 + 400
= 500
AE = √500
AE = 22.4cm

Find the values for x for which the expression 2x-3/(x+4)(x-2) is equal to 1/5
Answer:
1 and 7
Step-by-step explanation:
(x+4)(x-2) = x²+2x-8
set up proportion:
2x-3/ x²+2x-8 = 1/5
cross-multiply:
5(2x-3) = x²+2x-8
10x-15 = x²+2x-8
