7 0

Your answer is 14.13.
Heres how I got it:
First, the formula for area of a semi circle is 3.14 x r^2 and divide by two.
To find the radius, we need to divide the diameter by two, which is 3.
Now, lets plug in our numbers.
3.14 x 3^2/2
3.14 x 9/2
28.26/2
A=14.13

Area of circle = pi (d/2)^2
area of semi-circle =0.5* pi (d/2)^2
=0.5* pi (6/2)^2
=14.14

The question is incomplete:

Ava makes bead necklaces. She has a total of 6048 beads. Each necklace has 24 beads. Her friend maria says that the greatest number of necklace she can make with the beads is 162. Marias. Work is shown here. Explain why Maria is incorrect and how she can find the correct answer.

Answer:

Maria is incorrect because when you divide the number of beads by the beads in each necklace, you find that she can make 252 necklaces.

Step-by-step explanation:

You can find the number of necklaces Avan can make by dividing the number of beads she has by the amount in each necklace:

6048/24=252

According to this, you can say that Maria is incorrect because when you divide the number of beads by the beads in each necklace, you find that she can make 252 necklaces.

Can anyone please help

$\text{Hi there! :)}$

$\large\boxed{f'(2) = -\frac{16}{27} }$

$f'(x) = \frac{(5 + x^{2} )(-2x) - (7 - x^{2} )(2x)}{(5+x^{2})^{2} } \\\\f'(x) = \frac{-10x-2x^{3}- 14x + 2x^{3} }{(5+x^{2})^{2} } \\\\f'(x) = \frac{-24x}{(5+x^{2})^{2} }\\\\ \text{Solve for the derivative at f'(2) using substitution:}\\\\f'(2) = \frac{-24(2)}{(5+2^{2})^{2} } \\\\f'(2) = \frac{-48}{81} \\\\\text{Simplify:}\\\\f'(2) = -\frac{16}{27}$

X^4=15 <br> is an exponential equation?

miskamm [114]

Answer:

No. It is not an Exponential Equation.

Step-by-step explanation:

Given $x^{4} =15$

By the Definition of Exponential Equation which states.

"The equation is said to be an exponential equation when it has a variable occurred in the exponent and which have the same base."

For Example:

All given below are said to be exponential equations.

$5^{x} =5^{2} \\7^{x}=49\\$

which can be rewritten as

$7^{x}=7^{2}$

Now in the given equation $x^{4}=15$ it doesn't have same base neither any means the base can be made same,hence the given equation is not an exponential equation

KATRIN_1 [288]

Answer:

C = 200p + 400

Because C is the cost of a given day, 400 acts as a y-intercept.

400 is the initial fee paid then 200 per each phone manifactured, meaning that 200 is the slope.
