Answer:
It should be C
Step-by-step explanation:
B is a quadratic function and A is a linear line.
You are trying to find the side between the right angle and the degree (This is known as the adjacent)
You are given degree 42
You also given the longest side of 19 (This is known as the hypothenuse)
Cosine: adjacent/hypothenuse
Cos42 = x/19
0.7431448255 = x/19
x = 19 * 0.7431448255
x = 14.11975168, round to tenth
Solution: x = 14.1
The function with the smallest rate of change is B.
Rate of change is like slope, the vertical change over the horizontal change.
The horizontal change for each of these choices will be ONE since 3-2 = 1.
Plug 2 in for x to find y, then plug 3 in for x and find y. Subtract the y values and you will get the rate of change as follows:
A) 30
B) 7
C) 192
D) 12
If you need more explaining just let me know.
Answer:
y^2 - 5y - 4
Step-by-step explanation:
So you want f(y) such that
(y^2-5y+1) - f(y) = 5
Subtract both sides by (y^2-5y+1):
-f(y) = 5 - (y^2-5y+1)
-f(y) = -y^2 + 5y + 4
f(y) = y^2 - 5y - 4
So the polynomial you are looking for is y^2 - 5y - 4
Answer:
x=3/8
Step-by-step explanation:
turn 3/4 into a fraction that has a denominator of 8 3/4x2= 6/8
To get it to 9/8 you add x which is 3/8
so 3/8+6/8 is 9/8
x=3/8
