It will take 4.3 seconds for the ball to hit the ground
Given the eqation of the height at which the object dropped expressed as
h(t) = 300 - 16t²
The object will hit the ground at when h(t) = 0
Substitute h(t) = 0 into the expression to have;
0 = 300 - 16t²
16t² = 300
t² = 300/16
t² = 18.75
t = 4.33sec
This shows that it will take 4.3 seconds for the ball to hit the ground

Explain step by step of how you would find the scale factor for the following problem.
Answer:
Scale factor = 2.5.
Step-by-step explanation:
Work out the lengths of the corresponding sides.
The scale factor is the ratio of one side to the other.
Take the smallest length in both triangles.
Blue triangle:
length = √((7.5-2.5)^2 + (12.5-5)^2) = 9.0139 units.
Red triangle:
length = √((3-1)^2 + (5-2)^2) =3.6056
So the scale factor
= 9.0139/ 3.6056
= 2.5.

6. What is an equation in slope-intercept form for the line that passes through the points and (3, 1)? y= 3x + 1 y=x-3 y=2x + 5 y= 2x - 5
Answer:
The correct answer is D) y = 2x - 5
To find the equation of the line, start by finding the slope. You can do this by using the slope formula below.
m(slope) = (y2 - y1)/(x2 - x1)
m = (1 - -3)/(3 - 1)
m = 4/2
m = 2
Now that we have the slope, we can use it along with either point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 1 = 2(x - 3)
y - 1 = 2x - 6
y = 2x - 5
Answer: y=2x-5
the points are 4 points away from each other vertically, and 2 away horizontally. This makes the slope 4/2 or just 2.
take the slope and go backwards until you hit the y axis and the y-intercept is -5
this means the equation is y=2x-5

if ab=12 and a^2+b^2=25 ,then what is (a+b)^2=
Answer:
49
Step-by-step explanation:
Multiply out (a+b)^2
(a+b)^2 = (a+b)(a+b) = a^2 + ab + ba + b^2 ; not ab = ba so,
= a^2 + 2ab + b^2 = a^2 + b^2 + 2ab ; now subtitue in given values
=25 + 2(12) = 25 + 24 = 49
So (a+b)^2 = 49
Evaluate: [(1/2)^2-(1/4)^3]
Answer:
15/64
Step-by-step explanation:
Evaluate:
[(1/2)²-(1/4)³]
We have to find the value of expression ?
Explanation:-
Given that
[(1/2)²-(1/4)³]
⇛ [{(1/2)×(1/2)}-{(1/4)×(1/4)×(1/4)}]
⇛ [{(1×1)/(2×2)}-{(1×1×1)/(4×4×4)}]
⇛ [(1/4)-(1/64)]
LCM of 4 and 64 = 64
⇛ [(1×16)-(1×1)]/64
⇛ (16-1)/64
⇛ 15/64
The value of the given expression is 15/64.

Enter your answer in the box.
x =
I guess the number 2 is to indicate the question...
Then the equation would be 1/3 - 1/2x = -2/3
1/3 - 1/2x - 1/3 = -2/3 - 1/3
-1/2x = -3/3
-1/2x = -1
-1/2x *2 = - 1*2
-x = -2
-x * -1 = -2 * -1
x = 2
