Answer:

  the resulting error is about 0.754 in²

Step-by-step explanation:

  A(r) -A(r0) ≈ dA/dr·(r -r0)

The area of a circle is given by ...

  A(r) = πr²

so the derivative is

  dA/dr = 2πr

and the area error is ...

  dA/dr·(r -r0) = 2π(12 in)(0.01 in) = 0.24π in² ≈ 0.754 in²

How many solutions does the equation −5a 5a 9 = 8 have? none one two infinitely many
Brut [27]

The given equation does not have any solution.

For given question,

We have been given an equation −5a + 5a + 9 = 8

We know that the like terms are those terms which have same variable to the same power.

Combine Like terms;

0 + 9 = 8

9 = 8

⇒ which is  False.

This statement is false for any values of x

Therefore, the given equation does not have any solution.

Amy can paint a room in 12 hours. Alicia can paint the same room in 16 hours. How long does it take for both Amy and Alicia to p
Simora [160]
Well 12 is 3\4 of 16 so honestly it would take the 8 hours working together.

As far as formula if I had to guess it would look like.. 12Amy(Ay)- 16Alicia(Aa) = 4 hours minus 4 from Amy would be 8hours.

in fraction form might make more sense. 3\4 - 4\4 = 1/4 minus that from Amy and she'll finish together with Alicia 4 hours quicker being 8hours.

Answer:

35 units²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = \frac{1}{2} bh ( b is the base and h the perpendicular height )

Here b = 14 and h = 5, thus

A = \frac{1}{2} × 14 × 5 = 7 × 5 = 35 units²
