Just the first one, r is 4x+2, and h is 5x+4, plug them into the formula pls
The rate of increase is found by differentiating with resepect to time. The product rule comes into play here.
A = LW
dA/dt ≈ (dL/dt)·W + L·(dW/dt)
... = (6 cm/s)·(5 cm) + (7 cm)·(3 cm/s)
... = 30 cm²/s + 21 cm²/s
... = 51 cm²/s . . . . rate of area increase
Answer:
1.
d. (-14) + (-8)
2.
a. (-14) + 8
Step-by-step explanation:
(-14) - 8 is equal to (-14) + (-8) because we still add two negative values so the result wouldn't change.
(-14) - (-8) is equal to (-14) + 8 because there's two negative sign in front of 8 and two negative values multiplied makes a positive result.
Your answer should be 126.4 (rounded)
Answer:
<u>If You divide 2 integers with different signs it will be negative, but to make it positive you divide the absolute values. So, only if one integer is negative and one is positive will the answer be negative</u>
Step-by-step explanation:
EXAMPLE: 8÷ (-4)=-2 but when using absolute value |8|÷ |4|=2
HOPE THIS HELPS!!!
