The diameter of a circle is 7 in. Find its area to the nearest tenth.

Answers

Answer 1

A = πr^2
D = r • 2
R = D/2
7/2 = 3.5
R = 3.5

A = πr^2
A = 3.14 • 3.5^2
A = 3.14 • 12.25
A = 38.465
A = 38.47

So therefore the area of the circle is 38.47!

G(x)=\sqrt{x+3}g(x)= x+3 g, left parenthesis, x, right parenthesis, equals, square root of, x, plus, 3, end square root What is the domain of g?G?

Answers

Answer:

The domain of g(x) is -3 to infinity

Step-by-step explanation:

Given

[tex]g(x) = \sqrt{x + 3}[/tex]

Required

Determine the domain of g(x)

We start by expressing the content of the square root in the following form:

[tex]x + 3 \geq 0[/tex]

Subtract 3 from both sides

[tex]x + 3 -3 \geq 0 - 3[/tex]

[tex]x \geq 0 - 3[/tex]

[tex]x \geq - 3[/tex]

This can be expressed using interval notation as follows:

[tex]\{x: -3, infiniti\}[/tex]

Hence, the domain of g(x) is -3 to infinity

Adding -5 is like subtracting 5

3 -5

-2

Answer:

-2

Step-by-step explanation:

You need to add a positive number and a negative number.

This is how you add a positive number and a negative number.

First, get rid of the signs and make them both positive.

Now you have 5 and 3.

Do a subtraction the way you first learned subtraction in elementary school, which is the larger number minus the smaller number.

5 - 3 = 2

The answer is either 2 or -2.

To finish the original addition, look at the two original numbers. 5 is greater than 3. 5, the greater value, is on a negative number, so the answer is negative.

3 + (-5) = -2

Answers

Answer:

Step-by-step explanation:

First of all, the area of a circle is always pi(r)^2, which we can then substitute values. We will get pi(10)^2, and once we simplify that, we get 100pi as the area. Since we know that the area of the shaded sector is 10 pi, we can divide 10pi by 100pi to get 1/10. 1/10 is the area of the shaded sector compared to the area of the whole circle. Multiply 1/10 by the angle measure of a circle, which is 360, to get 36 degrees.

Step-by-step explanation:

Each point is moved 4 units up and 5 units right, as required by the problem statement.

Coordinates are positive in the "up" and "right" directions, so we take "4 units vertically" to mean +4 units, or 4 units up. Likewise, we take "5 units horizontally" to mean +5 units, or 5 units to the right.

A : yes, dakota is correct

B: No. The answer should have been 11 milliliters, not -11 milliliters, because the volume should not be negative

C: No. Dakota should have subtracted 20 - (-9) because the volume decreased

Hey there!

While working with them remember some rules;

(-) + (-) = sign (-) but add them.(+) + (+) = sign (+) and add.(+) - (+) = subtract but keep sign of greator number. (-) -(-) = subtract and keep the sign of greator number.

Likewise in your question,

[tex] = - 6 - 4 + 3[/tex]

[tex] = - 10 + 3[/tex]

[tex] = - 7[/tex]

Hope it helps...

-6 + -4 + 3 = -7
basically, even though there's a plus sign with negative 4, you still subtract it since it's a negative.

If ∠ABD and ∠CBD are a linear pair, m∠ABD = (3x+31)°, m∠CBD = (2x-6)°, then find m∠ABD. *

Answers

Answer:

∠ ABD = 124°

Step-by-step explanation:

A linear pair of angles sum to 180°, thus

∠ ABD + ∠ CBD = 180 , substitute values

3x + 31 + 2x - 6 = 180, that is

5x + 25 = 180 ( subtract 25 from both sides )

5x = 155 ( divide both sides by 5 )

x = 31

Thus

∠ ABD = 3x + 31 = 3(31) + 31 = 93 + 31 = 124°
