Answer:
B. 20
Step-by-step explanation:
Cos a = b/c
Cos 53° = b/25
b = 25 × 0,6 = 15
x = √(25² - 15²)
x = √(625 - 225)
x = √400
x = 20
Answer: 1/4, 4/7, 5/8
Step-by-step explanation: There are three ways:
1. <u>Convert each to a decimal: </u>
1/4 = 0.25
4/7 = 0.571
5/8 = 0.625
2. <u>Convert to a common denominator:</u>
It looks like we can multiply each by a whole number that will result in a denominator of 56:
1/4 *(14/14) = 14/56
4/7*(7/7) = 35/56
5/8 *(8/8) = 32/56
Now they can be directly compared to get the answer.
3. <u>Estimate the values. </u>
5/8 is clearly larger than 1/4. 4/7 is somewhere in between. Therefore, 1/4, 4/7, 5/8

Answer:
2
Step-by-step explanation:
Linear equation form: y = mx + b
(where m is the slope and b is the y-intercept)
The rate of change for a line is the slope.
Function 1: y = 6
⇒ the slope is zero so the rate of change is zero
Function 2: y = 2x + 7
⇒ the slope is 2 so the rate of change is 2
Therefore, 2 - 0 = 2
So the rate of change of function 2 is 2 more than the rate of change of function 1
