(10 points) Solve for x. Assume that the lines which appear to be tangent are tangent

Ganezh [65]3 years ago

The two tangent lines for each circle are the same length. Set the equations to equal and solve for x.

1. 4x + 3 = 3x +12

Subtract 3x from each side:

x +3 = 12

Subtract 3 from both sides:

x = 9

2. -2 + x = 2x -7

Subtract 2x from both sides:

-2 - x =  -7

Add 2 to each side:

-x = -5

Multiply both sides by -1:

x = 5

joanna split three pitchers of water equally among her eight plants.what fraction of a pitcher did each plant get
Valentin [98]

Answer: \dfrac{3}{8}

Step-by-step explanation:

Given : Joanna split three pitchers of water equally among her eight plants.

i.e. The total number of pitcher plants = 8

The number of pitcher plants split by Joanna = 3

Then , the fraction of a pitcher did each plant get is given by :-

\dfrac{\text{No. of plants splits}}{\text{Total number of plants}}\\\\=\dfrac{3}{8}

Hence, the fraction of a pitcher did each plant get = \dfrac{3}{8}

Is it true that: If f"(c) > 0, then the slope of
zheka24 [161]

Answer:

yes

Step-by-step explanation:

the FIRST derivative of a function tells us the slope of a tangent line to the curve at any point. if is positive, then the curve must be increasing. If is negative, then the curve must be decreasing.

the SECOND derivative gives us the slope of the slope function (in other words how fast the slope of the original function changes, and if it is accelerating up - positive - or if it is avengers down - negative).

so, the first derivative would be fully sufficient to get the answer of if the slope of the function at that point is positive or negative.

but because it is only a "if" condition and not a "if and only if" condition, the statement is still true.

there are enough cases, where the slope is positive, but the second derivative is not > 0 (usually = 0).

but if even the second derivative is positive, then, yes, the slope of the original function must be positive too.
