Answer:
(b + 2)^2
Step-by-step explanation:
b^2 + 4b + 4
It's perfect square: a^2 + 2ab + b^2 = (a + b)^2
So
b^2 + 4b + 4 = (b + 2)^2
Answer:
-14
Step-by-step explanation:
Multiply the is together. Multiply the j's together. Add the answer. The answer is a scalar.
(7 × -2) + (5 × 0)
= -14
The height of the ball according to the function h(t) is 16 feet after 1.92 seconds and after 0.46 seconds.
A function is defined as a expression containing one or more variables.
Technically speaking, a function is a means of linking a set of inputs to a set of outputs.
The height of the ball at any time t is given by the function:
Now the required height of the ball(in feet) is 16 feet. We have to find the value of t for which h(t)=16.
Let us substitute the values:
This is in the form of a quadratic equation in t.
Solving by using the quadratic formula:
We know that for a quadratic equation
Therefore for the above quadratic equation:
Therefore the ball reaches the height of 16 feet at times 1.92 seconds and at 0.46 seconds.

Sorry if my answer was bad.
Answer:
29/12
Step-by-step explanation:
In an isosceles triangle, two sides are equal.
Therefore:
25/6+25/6+u = 10 3/4
50/6+u=43/4
u=43/4-50/6
u=43/4-25/3
u=129/12-100/12
u=29/12
