Answer:
28
Step-by-step explanation:
Add the top and bottom bases, divide by 2, multiply by height.
Sin 16 because cos and sin are similar
Answer:
x = 133
y = 43
Step-by-step explanation:
x + 47 = 180
so x is 133
47 + y = 90
so y is 43
Y=12+2x
y represents the number of pieces she now knows, x represents the number of weeks she has taken lessons, 2 is the slope (the number of pieces she'll learn each week), and 12 is the y intercept (the number of pieces she knew before taking lessons).
To solve the equation for 11 weeks, we replace x with 11.
2×11+12= 24
y=24
Hi there!
We know that:
f(1) = 6
F(n) = F(n - 1) + 2 (Meaning, the next "n" is 2 added to the previous)
We can count up to f(4) using this logic:
f(2) = F(2 - 1) + 2 = F(1) + 2 = 6 + 2 = 8
f(3) = F(2) + 2 = 8 + 2 = 10
f(4) = F(3) + 2 = 10 + 2 = 12
