Find the compound interest on $7000 invested over 7 years at 12% per annum, compounded annually.

You gave us the speed and the frequency, and you need the wavelength.

You were also nice enough to remind us that (fqy)x(lng) = speed.

So . . . F x W = 343 m/s

Divide each side by F :

W = (343 m/s) / F

W = (343 m/s) / (240 / s)

W = (343/240) m

W = 1.429 meters

Answer: A.1100

Step-by-step explanation:

Hi, to answer this question we have to round each number to the nearest whole number:

110.4 = 110 (.4 is less than 5)

10.2 = 10

The product is the result of the multiplication of both numbers:

110 x 10 = 1,100

So, the correct option is A.1100

Answer:

3.3 Pound

Step-by-step explanation:

in this problem we have to convert kilogram value to its equivalent pound value.

we know

1 KG = 2.205 Pound

since we have to find value of 1.5 kg

we multiply both LHS and RHS by 1.5

1 * 1.5 KG = 2.205 * 1.5 Pound

=> 1.5 KG = 3.307 Pound.

Since , in option value is rounded to 1 decimal place,

hence correct choice is 3.3 Pound

Answer:

Step-by-step explanation:

The height of the rocket at time t is given by the function h = -16t + 240t. The rocket explodes at its highest point, which occurs at the vertex of the parabolic path described by this function.

The vertex of the parabola h = -16t^2 + 240t can be found using the formula t = -b/2a, where a is the coefficient of the squared term (-16 in this case) and b is the coefficient of the linear term (240 in this case).

In this case, a = -16 and b = 240, so the time t at which the rocket reaches its highest point is:

t = -b / 2a

t = -240 / (2 * -16)

t = -240 / -32

t = 7.5

Therefore, the rocket reaches its highest point 7.5 seconds after it is launched, and it explodes at this point.

Note that the negative value for t obtained in the equation t = -b/2a is ignored in this case, since time cannot be negative.

Answer: The new mean will be less than 7.9 years

Step-by-step explanation:

The mean is the same thing as the average.  Because 0.5 is less than 7.9, the average will also decrease.

Hope it helps <3

Answer:

Hey there!

The new mean will be less than 7.9 years of age.

The mean is the average, thus if you add something below the average, the entire mean will decrease, and if you add something above the average, then vice versa.

Hope this helps :)

Answer:

Step-by-step explanation:

Please include the answer choices.  Thank you.

Start with y = |x|.  Plot the vertex at (0, 0).  Draw the line y = x in the first quadrant, not below y = 0, for positive x values.  Draw the line y = -x in the second quadrant, not below y = 0, for negative x values.

This gives you a v-shaped graph with vertex at (0, 0).

Going back to the given problem:

Reflect the graph of y = |x| in the x-axis, so that the vertex is now (0, 0) and the v-shape opens down.

Finally, translate this resulting graph upward by four units.

6,2

Answer: a

Step-by-step explanation:

if you look on the x axis and go from the far left to 0 you can see the y values go up and increase.

The y- values as the negative x- values get closer to zero is they decrease the correct option is B.

There are many tools we can use to find the information of the relation which was used to form the graph.

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.

If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.

We are given that;

The function= y = 10/x^2

Now,

As x gets closer to 0 from the negative side, x becomes a larger negative number in magnitude. When we substitute a large negative value for x in y = 10/x^2, the square of this negative number becomes a large positive number, and the fraction 10/x^2 becomes a small positive number.

For example, if we substitute x = -2 into y = 10/x^2, we get:

y = 10/(-2)^2 = 10/4 = 2.5

If we substitute x = -10 into y = 10/x^2, we get:

y = 10/(-10)^2 = 10/100 = 0.1

Therefore, by the graphed function the answer will be they decrease.

Answer:

The answer is "141.56 yd".

Step-by-step explanation:

In the given question an image file is missing, that can be defined as follows:

Formula:

[tex]c ^ 2 = a ^ 2 + b ^ 2 - 2 \times a \times b \times \cos C[/tex]

Let assume C is the third side:

[tex]c ^ 2 = 355 ^ 2 + 240 ^ 2 - 2 \times 355 \times 240 \times cos 16^{\circ}\\\\[/tex]

[tex]c^2=126025+57600- 170400(0.96)\\[/tex]

Simplified it is 2

So basically all you have to do is find the area of one of the smaller semi circles by using the formula for the area of a circle (A=πr^2). You know that the length of the larger semi circle's radius is equivalent to 6 cm because the radius of the smaller ones are 3 cm, meaning the diameter would have to be 6 cm and in this case, the length of the smaller semi circles' diameters is equal to the radius of the big semi circle. Then you would find the area of the big semi circle again by using the area of a circle formula, but after getting the answer you would half it, obviously because it's a semi circle. Subtract the are of the smaller semi circle you found earlier from the answer you just got and that's it ;) (you wouldn't have to half the area since there are two smaller semi circles and 1/2 + 1/2 = 1 but u knew that)

Put simply, the answer would be about 88.2644 cm because circles.
