The amount invested in the account that gives a 5.25% interest is  $18400.

The amount invested in the account that gives a 3.75% interest is 27600.

0.0525a + 0.0375b = 2001 equation 1

a + b = 46000 equation 2

Where:

a = amount invested in the account that gives a 5.25% interest

b = amount invested in the account that gives a 3.75% interest

Multiply equation 2 by 0.0525

0.0525a + 0.0525b = 2415 equation 3

Subtract equation 1 from equation 3

414 = 0.015b

b = 27600

Subtract 27600 from 46000

46000  27600 = $18400

Answer: CIRCLE C

Step-by-step explanation:

Answer:

Let the diameter be represented as x.

Let the diameter be represented as x.Based on the secant-tangent theorem, the following equation representing the relationship between the segments would be:

segments would be:(14 + x)(14) = 25^2

segments would be:(14 + x)(14) = 25^2196 + 14x = 625

segments would be:(14 + x)(14) = 25^2196 + 14x = 625Subtract 196 from each side

14x = 625 - 196

14x = 625 - 19614x = 429

Divide both sides by 14

Divide both sides by 14x = 429/14

Divide both sides by 14x = 429/14x = 30.6

Divide both sides by 14x = 429/14x = 30.6Diameter = 30.6

A Parallelogram because it is a quadrilateral with 2 pairs of parallel sides!

that is the complete answer to the question

The volume of the water storage tank is the amount of space in it

The volume of the water storage tank is 6468 cubic feet

The given parameters are:

Radius (r) = 21 feet

Height (h) = 14 feet

The shape of the water storage tank is a cone.

And the volume of a cone is:

V = 1/3πr^2h

So, we have:

V = 1/3 * 22/7 * 21^2 * 14

This gives

V = 6468

Hence, the volume of the water storage tank is 6468 cubic feet

Step-by-step explanation:

Answer:

No.

Step-by-step explanation:

Well, honestly not sure how to solve this but I'll try.

Each correct answer is giving 4 points but the probability to choose the correct one is 1/5

Each incorrect one gives -2 points and the chance to pick a wrong answer is 4/5.

Obviously, the chance to lose points is more. But is taking the risk and guessing worth it? Well, it depends on how many points the correct answer gives. If it makes up for the possible loss of points, then it is in his interest to guess, otherwise he will end up losing more than they win.

If we sum the two chances to find averagely how many points the student will get, then I guess that would be the correct answer:

4(1/5) + (-2)(4/5) = 4/5 - 8/5 = -4/5

He will get averagely -4/5 points, so I believe it isn't in his interest. It means that the points he gets don't make up for the possible loss of points if you choose answers randomly. (Wow, I'm glad teachers don't do this on tests 0_0)

This is my theory though, not sure how to go for solving this, just thinked logically. I hope this helps, but don't trust me and copy paste my answer on your test or whatever. Think if this is correct first because I'm not sure

A = 12•7

A = 84 square meters

As

<IJK and <IKJ are equal measured

The triangle is isoceles

The adjacent sides of both angles are similar

Hence

Answer:

21

Step-by-step explanation:

as angle J and angle K are equal, sides JI and IK are also equal. So y = 21

The coordinates of the point equidistant from their position is C(x,y) = (2, 3) and the equation of the locus is (x - 2)² + (y - 3)² = 2.

The center is the point that is equidistant to every point on the circumference. First, we need to determine the coefficients of the general equation of the circle, whose form is described below:

x² + y² + D · x + E · y + F = 0   (1)

We need three distinct points of the circumference to determine one solution.

If we know that (x₁, y₁) = (1, 2), (x₂, y₂) = (3, 4) and (x₃, y₃) = (3, 2), then the system of linear equations is:

D + 2 · E + F = -5   (2)

3 · D + 4 · E + F = - 25   (3)

3 · D + 2 · E + F =  - 13   (4)

The solution of the linear system is D = - 4, E = - 6 and F = 11.

Now we proceed to transform the expression into its standard form by completing the squares:

x² + y² - 4 · x - 6 · y + 11 = 0

(x² - 4 · x + 4) + (y² - 6 · y + 9) - 2 = 0

(x - 2)² + (y - 3)² = 2

The coordinates of the point equidistant from their position is C(x,y) = (2, 3) and the equation of the locus is (x - 2)² + (y - 3)² = 2.
