The first statement and the second statement are FALSE.
In mathematics, a function<span> is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the </span>function<span> that relates each real number x to its square x</span>2<span>.
</span>
I hope my answer has come to your help. God bless you and have a nice day ahead!
Thee function is given as:
<span>v(t)=t^2−2tv(t)=t^2−2t
</span>(a) What is the initial velocity?
Base from the function, the initial velocity would be zero.
(b) When does the object have a velocity of zero?
It would be during time zero. Also, at a time equal to two.
Answer:
<u>The correct answer is A. - 11 square root of 7.</u>
Step-by-step explanation:
We have the expression 2 √28 - 5 √ 63 and we have to find and equal expression.
Let's simplify it:
2 √28 - 5 √ 63
2 √7 * 4 - 5 √ 9 * 7 (28 is also equal to 7 * 4 and 63 is equal to 9 * 7)
2 * 2 √7 - 5 * 3 √ 7
4 √7 - 15 √7
- 11 √7
<u>The equal expression is A. - 11 square root of 7.</u>
Answer:
a and e
Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
(2x + 20) + 130 = 180
2x + 150 = 180
- 150 - 150
2x = 30
/2 /2
x = 15
