Answer:
180°
Step-by-step explanation:
A parallelogram has rotational symmetry of degree 2. That is, it maps to itself when rotated through angles that are multiples of 360°/2 = 180°.
The figure should be rotated 180 degrees.
It should be 8 if it is 5-5 which gives you 0.
Or it could be (5x5)-5=20+8=28.
Answer:
-19+-25f≤-144
Step-by-step explanation:
The problem says that you descended 19 below sea level. Below makes 19 into a negative. It also says that it descends 25 feet per minute. If it says per you put a variable by that number. It also says descends which means going down so that would be a negative. The problem says Lainey does not want to go over 144 feet(144 is also negative because it is below sea level) so 144 would be greater than or equal to because she does not wan to go over that amount.
Hope this helps!
Using a system of equations, it is found that Wilma is 50 years old and Yvonne is 10 years old.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given as follows:
- Variable y: Yvonne's age.
Wilma is 5 times as old as yvonne, hence:
x = 5y.
In ten years, yvonne's age will be a third of wilma's age, hence:
Since x = 5y:
3y + 30 = 5y + 10
2y = 20.
y = 10.
Then:
x = 5y = 5 x 10 = 50.
Wilma is 50 years old and Yvonne is 10 years old.

Answer:
The rate of change of the function given = 3288
Step-by-step explanation:
Given in the question the equation:
G(t) = 100(1.037)24t
The average rate of change of function is given by this expression:
<h3>f(b) - f(a) / (b - a)</h3><h3 />
cells present at start = when t = 0
a = 0
cells present after an hour = t = 1
b = 1
<h3>Put these values in the formula</h3>
f(1) - f(0) / (1 - 0)
100(1.037)24(1) - 100(1.037)24(0) / 1
3288 - 0 / 1
3288 / 1
3288
