Answer:
CB = sqrt62
Step-by-step explanation:
The pythagorean theorem will help with this! First take triangle ACD, AD^2 + CD^2 = AC^2. Plug in, AD^2 + 16 = 25. AD^2 = 9. AD = 3. I'm not exactly sure how to find DB, but I can assume it's double of AD< so 6. We know CD is 4, so 4^2 + 6^2 = CB^2. 16 + 36 = CB^2. CB = sqrt62
Sorry if this isn't exactly right, there's no exact way to find DB.
Your answer would be
B. the estimated average change in y per unit change in x
The y-intercept is (0,7) and the slope is - 0.8
- Find the product of (3a⁴ + 4)²
Use binomial theorem to expand .
To raise a power to another power, multiply the exponents. Multiply 4 by 2 to get 8.
0.12 because all the other ones have .00's behind them and .0= nothing so 12.00= 12 12.0= 12 and 0.12=0.12.
