Answer:
inches
Step-by-step explanation:
Let x inches be the length of one side of the frame. The frame is the square, so all sides have the same lengths.
Use formula connecting the area of the square and the side length of the square.
Since the area ofthe square is 55 square inches, we have
<u><em>Answer:</em></u>The factored form is: (x-2)(x-4) = 0
<u><em>Explanation:</em></u>To factor an expression, we need to <u>get its solutions</u>.
<u>The standard form of the quadratic equation is:</u>
ax² + bx + c = 0
<u>The given equation is:</u>
x² - 6x + 8 = 0
<u>By comparison:</u>
a = 1
b = -6
c = 8
Now, to get the roots, we will substitute with the values of a, b and c in the quadratic formula shown in the attached image.
<u>This will give us:</u>
either x =
This means that
the first factor is (x-4)
or x =
This means that
the second factor is (x-2)
Based on the above, the factored form would be:
(x-4)(x-2) = 0
Hope this helps :)
Answer:
95 m
Step-by-step explanation:
If the graph shows the height of the balloon after t minutes from beginning of descent, look to when t = 0. At t=0 it has not yet begun it's descent because no minutes have passed. At that point on the graph the height is 95 m (the point is (0,95))
Answer: x=4.5
Step-by-step explanation:
The question is in standard form as y = ax^2 + bx + c.
And as such, the axis of symmetry is given as x = - b / 2a
From the question above, a =1 and b = - 9
Therefore axis of symmetry is;
x = - (-9) / 2(1) which gives;
x = 9/2 or x=4.5
F(1) = 2
f(2) = -5f(2-1) = -5f(1) = -5(2) = -10
f(3) = -5f(3-1) = -5f(2) = -5(-10) = 50
So, f(4) = ?
