The height of the missile above the ground is 72 meters at 0.8 sec and 2 sec.
What is an equation?An equation is an expression that is used to show the relationship between two or more numbers and variables.
Let h(t) represent the height of the missile above the ground at time t. Given that:
h(t) = -16t³ + 100t
When the height is 72 m:
72 = -16t³ + 100t
16t³ - 100t + 72 = 0
t = 2 seconds and t = 0.8 seconds
The height of the missile above the ground is 72 meters at 0.8 sec and 2 sec.

Answer:

Step-by-step explanation:
6^2= b^2 + 2^2
b^2 = 36- 4
b^2= 32
b= √32
Answer:
√32
Step-by-step explanation:
The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , is used to find the length of any side of a right triangle.
6² - 2² = b²
36 - 4 = b²
32 = b²
Five positive integers have
a mode of 9,
and a median of 7,
and a mean of 6.
What is the greatest possible range of the five integers?
Answer:
5
Step-by-step explanation:
The mean is 6 and there are 5 intergers.
You'd multiply 5*6=30. That means that the sum is 30.
The values could be: 2 3 7 9 9
These values add up to 20
Have a mode of 9
Have a median of 7
Have a mean of 6
To find the range you would subtract 9 and 2. That gives you 5.
(i don't know if that's the greatest possible range. But 5 would be the range here)
How to factor a polynomial with a degree of 4.
Answer:
We can factor a difference of fourth powers (and higher powers) by treating each term as the square of another base, using the power to a power rule. For example, to factor x4 - y4, we treat x4 as (x2)2 and y4 as (y2)2. Thus, x4 - y4 = (x2)2 - (y2)2 = (x2 + y2)(x2 - y2) = (x2 + y2)(x + y)(x - y).

3x = 51 ( divide both sides by 3 )
x = 17
Step-by-step explanation:
Statement Reason
BD bisects ∠ABC Given
m∠ABD = (3x + 4)°, m∠DBC = 55° Given
∠ABD ≅ ∠DBC Definition of angle bisector
3x + 4 = 55 Definition of congruence

A 10 kg computer accelerates at a rate of 5 m/s2.how much force was applied to the computer
Answer:
50 N
Step-by-step explanation:
Given :-
Mass = 10 kg
Acceleration = 5 m/s²
To find
Force applied
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 10 × 5
We have the final answer as
50 N
(Hope this helps can I pls have brainlist (crown)☺️)
[tex]\purple{\longrightarrow \sf Force = Mass \times Acceleration}[/tex]
[tex]\longrightarrow \sf Force = 10 \; kg \times 5 \; m/s^2[/tex]
[tex]\longrightarrow \sf Force = 50 \; kgm/s^2[/tex]
[tex]\longrightarrow {\pink{\underline{\underline{\sf{ Force_{(Applied )} = 50 N }}}}}[/tex]
Henceforth :
The force applied on the computer is 50 N.

Ax) = ax + bx² + cx+d
x= -2, x=-1, x=2
Answer:
I'm assuming the equation "Ax) = ax + bx² + cx+d" is really meant to read:
A(x) = ax^3 + bx² + cx+d
A(x) = x^3 + x^2 -4x -4
Step-by-step explanation:
(x+2)*(x+1)*(x-2) [This reflect the fact that x= -2, x=-1, x=2 all result in a zero]
Multiply this out to get A(x) = x^3 + x^2 -4x -4
