Good evening ,
Answer:
<h2>f(8) = 74</h2>
Step-by-step explanation:
f(x) = x² + 3x – 14
Then
f(8) = 8² + 3(8) – 14
= 64 + 24 - 14
= 64 + 10
= 74

Answer:
D
Step-by-step explanation:
Divide the composite shape into 2 rectangles.
The dimensions of the 2 rectangles are :
Then, we plug in the values.
1st Rectangle
7 * (14 + 10)
7 * 24
168
2nd Rectangle
9 * 10
90
Then, we add together.
168 + 90 = 258
Long leg = 8 → opposite
short leg = 6 → adjacent
hypotenuse = ?
8² + 6² = c²
64 + 36 = c²
100 = c²
√100 = √c²
10 = c
sin ∠BOC = opposite / hypotenuse
sin ∠BOC = 8 / 10
sin ∠BOC = 0.80
tan ∠BOC = opposite / adjacent
tan ∠BOC = 8 / 6
tan ∠BOC = 1.33
1/10 of 30000 is 3000 because 30000 divided by 10 is 3000.
1. You already did it.
2. Table
3. t (years since 1990)
4. n (# of cigarettes sold)
5. (t, n)
6. You can see the distribution of the data pretty neatly. There are also many more advantages including it's easier to calculate standard deviation, easier to see the mean, mode and median, and it's also much easier to just tell the extrema of the dataset by just looking at the scattergram.
