Answer:
Step-by-step explanation:
Given expression which gives the distance is 16t².
Here, t = time or duration
For t = 20 seconds,
16t² = 16(20)²
= 6400 feet
For t = 21 seconds,
16t² = 16(21)²
= 7056 feet
For t = 22 seconds,
16t² = 16(22)²
= 7744 feet
For t = 23 seconds,
16t² = 16(23)²
= 8464 feet
Therefore, complete table will be,
t 20 21 22 23
h 6400 7056 7744 8464
Answer:
Step-by-step explanation:
Part A.
Coordinates of A and B are,
A(-2, 2) and B(3, 2)
Rule for dilation of a point (x, y) by a scale factor k about the origin,
(x, y) → (kx, ky)
If the points A and B are dilated by a scale factor 3, image points will be,
A(-2, 2) → A'(-6, 6)
B(3, 2) → B'(9, 6)
Part B.
Following the same rule of dilation about the origin by a scale factor of 
about the origin,
A(-2, 2) → D(-1, 1)
B(3, 2) → 
It would be negative.
Absolute value is basically asking how far away something is from 0.
So say you had a number, 7. 7's distance from 0 is 7, so it would still be 7.
However, when absolute value really plays in is negative numbers. If you had -7, the distance from 0 would still be 7. It wouldn't be -7, so the absolute value of -7 would be 7.
And a negative version of a number is always less than the positive number.
Hope this helped!
Answer:
Step-by-step explanation:
In this equation what is strange is probably using the letter a as the unknown, but this is a matter of choice we could have calle y or z for that matter. Then we will treat it ans any other equation and solve it.
-11 -5a = 6(5a+4)
-11 -5a= 30a + 24
-11 - 24 = 30a + 5a (placing the unknown a in the rght side and the numbers in the left to solve the equation)
- 35 = 35a
-35/35 = a
- 1= a
