Answer:
the object is in the air on the time interval (0.24 sec, 6.51 sec)
Step-by-step explanation:
The object is 'in the air' for all t such that h> 0. We need to find the roots of h = -16t^2 + 108t - 25 = 0. From the graph we see that both t values are positive. Once we find them, we subtract the smaller t from the larger t, which results in the length of time the object is in the air.
Use the quadratic formula to find the roots of h(t). The coefficients of t are {-16, 108, -25}, and so the discriminant b^2 - 4ac is
108² - 4(-16)(-25) = 11664 - 1600 = 10064, whose square root is 100.32.
Then the quadratic formula x = (-b ± √[b² - 4ac)/(2a) becomes
-108 ± 100.32 108 ± 100.32
t = ---------------------- = --------------------- = 3.375 ± 3.135
2(-16) 32
or t = 6.51 or t = 0.24 (both times expressed in seconds).
So, again, the object is in the air on the time interval (0.24 sec, 6.51 sec)
Referring to the figure, find the missing length.
Answer:
5 units
Step-by-step explanation:
here;
perpendicular (p)= 3
base (b) = 4
hypotenuse (h) = c= ?
By Pythagorean relationship;
h²=p²+b²
or, h= √(p²+b²)
or, c= √(3²+9²)
or, c= √25
hence, c=5

Write a division problem with a 3-digit dividend and divisor of 20 and remainder of 10. pls i need an answer
Answer:
y = 10x
(x is a set of odd numbers between 11 and 99)
Step-by-step explanation:
Given;
divisor = 20
remainder, = 10
let the 3 - digits dividend = y
let the quotient = x
Arranging all in mixed fraction;
[tex]\frac{y}{20} = x\frac{10}{20} \\\\\frac{y}{20} = \frac{10x}{20} \\\\\frac{y}{20} = \frac{x}{2} \\\\2y = 20x\\\\y = 10x[/tex]
where x = 11, 13, 15, 17, 19 - - - - - - - 99
The divisor would be between 5 and 49. So I chose 38. 38x20 is 760. 760+ 10 (which is the remainder) is 770.
Therefore, The divisor would be 38 and the dividend would be 770.
Have a great day!

You deposit $2500 in an account that pays 12% annual interest rate compounded continuously. Find the balance after 5 years.
Answer:
$4,555
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Total deposit (P) = $2,500
Annual interest (r) = 12%
Time period (t) = 5 years
We can calculate the balance after 5 years if compounded continuously by using following formula,
FV = P[tex]e^{rt}[/tex]
By putting the value, we get
FV = $2,500 × [tex]e^{(0.12 * 5)}[/tex]
= $2,500 ×[tex]e^{.60}[/tex]
= $2,500 × 1.822
= $4,555

If the weight reaches 20 feet to ring the bell, the
height of the weight if the initial velocity is 32 feet per second. Find
contestant wins a prize. The equation h = -167 + 32t + 3 gives the
part of the equation has
to change for the weak man' to win?
Answer:
19feet
Step-by-step explanation:
Given the expression for height of a man expressed as;
h = -16t² + 32t + 3
We are to find the maximum height reached by the man;
At the max height dh/dt = -32t + 32
v(t) = -32t + 32
0 = -32t + 32
32t = 32
t = 32/32
t = 1.sec
Substitute t = 1 into the expression given
h = -16(1)² + 32(1) + 3
h = -16 + 35
h = 19feet
Hence the maximum height reached by the man is 19feet

An exponential decay function represents a quantity that has a decreasing halving time.
Answer:
true
Step-by-step explanation:
Answer:
Yes, the statement "An exponential decay function represents a quantity that has a decreasing halving time" is true. In addition, this process can be expressed by the following differential equation, where N is the quantity and λ (lambda) is a positive rate called the exponential decay constant: d N d t = − λ N . {displaystyle {frac {dN} {dt}}=-lambda N.}

can I have help with question a and c
Answer:
a) ∠x = 59°
c) ∠x = 79°
Step-by-step explanation:
a) ∠x = ∠EIH because they are alternate interior angles
c) ∠BEF = 41° because they are alternate interior angles
the sum of all three interior angles of a triangle = 180°
∠x = 180° - 60° - 41° = 79°
Answer:
a.x=58°[alternate angle]
b.x=55°[alternate angle]
c.x=180-101=79°[co- interior angle]
d.x=134°[alternate angle]
