Answer:

(d) 810.34

Step-by-step explanation:

The explicit formula used for calculating the account's balance is given by:

A= P(1+R)^T

where: A= Amount (account's balance)

P= Principal  (700)

R= Rate (5%)

T= Time   (3 years) [since, the balance is calculated in the beginning of the  forth year]

A= P(1+R)^T

A = 700(1+0.05)^3

  = 700(1.05)^3

  = 700*1.157

  = 810.34

Step-by-step explanation:

Think of a box .... it has 4 sides, a top, and a bottom = 6 total sides

The shape with six equal square, flat sides is known as a cube.

A cube is a three-dimensional geometric shape characterized by six equal square faces. Each face of the cube is identical, and the shape is formed by connecting these faces at right angles. This regular polyhedron is fundamental in mathematics and has practical applications in various fields. Cubes are extensively used in geometry, trigonometry, and calculus to illustrate concepts such as volume and surface area. In addition to its mathematical significance, cubes are prevalent in everyday objects like dice and building blocks. Understanding the properties of cubes is crucial in engineering and architecture, where it aids in designing structures and solving spatial problems efficiently.

Answer:

The cost of one box of oranges = $3.3

Step-by-step explanation:

Let x be cost of one box of oranges and y be the cost of one box of grapefruit.

We have been given that Mrs. Whitten purchased 3 boxes of oranges and 2 boxes of grapefruit from a student for a total of $22.50. We can represent this information as:

[tex]3x+2y=22.50...(1)[/tex]  

Mr. Rutig purchased 1 box of oranges and four boxes of grapefruit, spending a total of $28.50. We can represent this information as:

[tex]x+4y=28.50...(2)[/tex]

We will solve our system of linear equations using substitution method.

From equation (1) we will get,

[tex]y=\frac{22.50-3x}{2}[/tex]

Substituting y's value in equation (2) we will get,

[tex]x+4*(\frac{22.50-3x}{2})=28.50[/tex]

[tex]x+2*(22.50-3x)=28.50[/tex]

Upon distributing 2 we will get,

[tex]x+45-6x=28.50[/tex]

[tex]x-6x=28.50-45[/tex]

[tex]-5x=-16.5[/tex]

[tex]x=\frac{-16.5}{-5}[/tex]

[tex]x=3.3[/tex]

Therefore, the cost of one box of oranges is $3.3.

In this exercise we have to use the knowledge of equations to write the intersection equation, so we have to:

The formula for setting up an equation is given by:

[tex](y - y1) = m(x - x1)[/tex]

1.) So by the formula above, substituting for the values ​​given in the statement, then:

[tex](y - 120) = -2(x - 7)[/tex]

2.) The equation in slope intercept form will be:

[tex](y - 120) = -2(x - 7)\\(y - 120) = -2*x + (-2*-7)\\y - 120 = -2x + 14\\y = -2x + 134[/tex]

Answer:

This equation has no solution

Step-by-step explanation:

To find our many solution the system of equation has, we need to  solve simultaneously, we can either solve by substitution method, by elimination method or both method.

We will be using substitution method to solve.

Here are the system of equation;

y= -4x+2 ----------(1)

24x+6y=6---------(2)

First, we are going to substitute equation (1) in equation (3)

{what we mean by substituting equation (1) in equation (2) is then any where we see y in equation (2),  we will be replacing it by[-4x + 2]}

24x + 6(-4x + 2)  = 6

Then, we will go ahead and open the bracket

24x  -  24x  +  12  =6

This simply shows that there is no solution to this system of equation

Answer:

[tex]y =\displaystyle\frac{1}{4}x^{0.5}[/tex]

It is a power function.

Step-by-step explanation:

We are given the following function in the question:

[tex]y =\displaystyle\frac{1}{4}x^{0.5}[/tex]

We have to check whether the given function is a power function or not.

Power Functions :

[tex]f(x) = ax^p,[/tex]

where a is a constant and not equal to zero and p is a real number.

Comparing the given function, we get:

[tex]a = \displaystyle\frac{1}{4}\\\\p = 0.5[/tex]

Hence, the given function is a power function.

The equation y = 1/4x^0.5 is a power function because it fits the general form of a power function, y = ax^n, with a constant coefficient and a real number exponent.

Yes, the function y = 1/4x^0.5 is indeed a power function. A power function is of the form y = ax^n, where a is a constant and n is a real number, representing the power of x. In the given function, a is equal to 1/4, and n is 0.5, which is equivalent to the square root of x (since raising a number to the 0.5 power is the same as taking its square root).

Therefore, we can express the square root of x as x raised to the power of 1/2, fitting the form of a power function.

Answer:

c = 36

Step-by-step explanation:

Use the formula (b/2)^2 to solve for the max or min.

6^2 = 36

You can check you work

y = x^2 + 12x + 36

Multiply both sides of the ratio by 4.

4 * 1 inch : 4 * 30 yards

4 inches : 120 yards

Answer:

So we know 4 inches  is 120 yds

Step-by-step explanation:

We can use ratio's to solve this problem

1 inch           4 inch

------------ = --------------

30 yds         x yds

Using cross products

1 * x = 30*4

Answer:

127.3

Step-by-step explanation:

The formula you gave is is known as the Pythagorean Theorem.

It is used to find the hypotenuse (longest side) of a right triangle with the lengths of the other two legs (sides).

Here, a is the hypotenuse of two adjacent triangles. Both triangles are right triangles, and have legs (not including the hypotenuse) of 90 ft.

Now, the formula is a^2 + b^2 = c^2.

A and b are the two shorter legs of the triangle: 90 and 90. Let's insert these values into the formula.

90^2 + 90^2 = c^2

90^2 is 8100, and 8100 plus 8100 is 16200.

16200 = c^2 (c is the hypotenuse, or a)

Now, we just have to find the square root of 16200.

sqrt16200=127.27....

When we round this to the nearest tenth, we get 127.3.

Answer:

The possible outcome could be 4 or 3

Step-by-step explanation:

Answer:

2/3

Step-by-step explanation:

There are 12 possible outcomes. Of the 12, 6 are even and 4 have B's. That would give up 10/12. But then you would subtract the possible outcomes that are BOTH even AND have a B. Only 2 possible outcomes have an even number and the letter B. So 10 minus 2 is 8. That would give you 8/12. Simplify and you will get your answer of 2/3!

Step-by-step explanation:

For Number 1 you need one more thing to prove that the triangles are congruent. You could see that there is a pair of vertical angles and vertical angles are congruent so you could use that. Angle DEA is congruent to Angle CEB. When there is a side in between two congruent angles, that is ASA.

For Number 2 it really is almost the same as number 1. First you write the given, then you write that angle DEA is congruent to angle CEB and the reason for that is that vertical angles are congruent. Lastly, you say that triangle ADE is congruent to triangle CBE.
