Answer:

about 43% or 43.3%

Step-by-step explanation:

First, add up the total amount of computers in the computer lab:

14 + 16 = 30

We are told that 16 of the 30 computers are laptops so we can think of this percentage problem as its own equation

13    is    what percent   of  30

13    =            %              x     30

now to solve by dividing 13 by 30 using a calculator:

13/30 = 0.433...

This approximates to 43% or 43.3%

Dilation

By maintaining the object's orientation or shape, this type of translation either expands or contracts the object. This is referred to as resizing.

What is Graph Transformation?

A graph can be transformed to produce a different version of the one that came before it. The x-y plane can be used to translate or shift the graphs. In addition to these modifications, they may also be stretched.

Types of Stretching of Graphs

Consider the case where we need to lengthen a graph by a factor of 2. Next, change the y value. Now, each point of the function F's form (x, y) shifts to the point (x, 2y)*

Adjust the x value if a graph needs to be stretched horizontally by a factor of two. The point (2x, y) in function F is now the new location for all points with the form (x, y) in function F.

Types of Translation in Graphs

A graph is horizontally translated by moving the base graph to the left or right in relation to the x-axis. Consider that if we want to move a graph horizontally by 1 unit, we would also need to change the x value.

A graph's base graph is moved up or down in the y-axis direction when it is vertically translated. Each point on a graph is moved b units vertically to translate the graph in that many directions.

Answer:

Step-by-step explanation:

Filter out the - 2

y =   -2 ( x^2 - 5/2 x)     - 1      Now 'complete the square'

y = -2 ( x^2 - 5/2x + 25/16)  +  50/16     -1      Now simplify:

 =   -2(x-5/4)^2 + 34/16         This will have vertex at  5/4, 34/16

To find an expression for V(t), we can integrate V'(t) with respect to t. Doing so, we have:

V(t) = ∫V'(t) dt = ∫5700(t − 10) dt = 5700 ∫(t − 10) dt = 5700 [t^2/2 - 10t] + C

Since V(t) is the resale value of the computers, the constant of integration C should be the initial value of V(t), which is the cost of the computers. Therefore, we have:

V(t) = 5700 [t^2/2 - 10t] + 300000

Now, to find the value of the computers after 5 years, we can substitute t = 5 into the expression for V(t):

V(5) = 5700 [5^2/2 - 10*5] + 300000 = 5700 [25/2 - 50] + 300000 = 5700 [-12.5] + 300000 = -67500 + 300000 = 232500

Thus, the computers would sell for approximately $232,500 after 5 years.

Explanation: The function V'(t) gives the rate at which the resale value of the computers changes with time. In other words, it gives the slope of the function V(t) at any point in time. To find the function V(t) itself, we need to integrate V'(t) with respect to t. The constant of integration C is added to the result of the integration to ensure that the initial value of V(t) is equal to the cost of the computers. Once we have the expression for V(t), we can find the value of the computers at any point in time by substituting the appropriate value for t into the expression. In this case, we found that the value of the computers after 5 years is approximately $232,500.

Step-by-step explanation:

2272-875=1397

Factors of 1397: 1, 11, 127, 1397

Where's the three-digit number? ==> 127 is the three-digit number

875/127 = 6.889

1397/127=11

2272/127=

(875+1397)/127=

875/127 + 1397/127=  ==> substitute 11 for 1397/127 and 6.889 for 875/127

6.889 + 11 = 17.889

Hence, 2272/127=17.889

Hence, 2272 and 875 have the same remainder when divided by 127.

Let m s the slope of the given equation 2y+3x-1. So m=-3/2.

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by Δy and Δx, respectively. Consequently, the formula for the change in y-coordinate with respect to the change in x-coordinate is

m =Δy/Δx = change in y/change in x

where "m" represents a line's slope.

Slope can also be written as

tanθ  = Δy/Δx

The given equation is:

2y+3x-1=0

The vertical asymptotes can be simply found by equating the denominator of a function to zero and solving for x, but the vertical asymptotes requires consideration of the highest degrees of x in numerator and denominator.

A vertical asymptote is a vertical line that guides the graph of the function but is not part of it. Because it appears at an x-value outside of the function's scope, the graph can never cross it. There may be several vertical asymptotes for a given function.

A graph's horizontal asymptote is a horizontal line with the equation y = b, where the graph moves closer to the line as the inputs go closer to 0 or -1.

Find the x values where the function is undef for the purpose of determining a function's vertical asymptotes. Consider the degree of the numerator and the degree of the denominator while looking for a function's horizontal asymptotes. The horizontal asymptote is y = 0 if the degree of the numerator is smaller than the degree of the denominator. There is no horizontal asymptote if the degree of the numerator is higher than the degree of the denominator. The horizontal asymptote is y = the coefficient of the highest-degree term in the numerator divided by the coefficient of the highest-degree term in the denominator if the degree of the numerator and denominator are equal.

The equation x² + 4x = 0 has no real roots for any value of k.

The equation x² + 4x = 0 can be solved by using the Quadratic Formula. We can rearrange the equation to be in the form of ax² + bx + c = 0. In this case, a = 1, b = 4 and c = 0. We can then plug these values into the Quadratic Formula to find the roots of the equation.

The Quadratic Formula is x = [-b ± √(b² - 4ac)] / 2a

Plugging in our values of a, b, and c we get: x = [-4 ± √(-4² - 4(1)(0))] / 2(1)

Simplifying this equation we get: x = [-4 ± 0] / 2

The equation simplifies to: x = [-4 / 2] and x = [0 / 2].

Step-by-step explanation:

To solve this problem, we need to use the formula for simple interest, which is I = PRT, where I is the interest earned, P is the principal amount, R is the interest rate, and T is the length of time the money is invested. We know that I = 1350, P = 3000, and T = 9, so we can rearrange the formula to solve for R: R = I / (P * T) = 1350 / (3000 * 9) = 0.05. Therefore, the interest rate is 5%.

Answer: 5% per year

Step-by-step explanation:

First, take 1350 divided by 3000, then times 100% = 45% for 9 years

Then take 45 divided by 9 = 5% per year

The roots of the quadratic equation 2x² + 5x + 3 = 0 are x = -3 and x = -1/2.

To find the roots of a quadratic equation, we must first convert the equation into the standard form ax² + bx + c = 0. In this case, the given equation is already in this form, so we can proceed with solving. To solve, we use the quadratic formula, which is x = (-b ± √(b² - 4ac))/2a.So, we have x = (-5 ± √(25 - 4(2)(3))/2(2). Simplifying, we get x = (-5 ± √(13))/4. The quadratic formula yields the values x = -3 and x = -1/2. Therefore, the roots of the quadratic equation 2x² + 5x + 3 = 0 are x = -3 and x = -1/2.

The quadrants are generated when the two axes, the x-axis and the y-axis, cross at a 90-degree angle. These areas include coordinates, or positive and negative values of the x- and y-axes. The intersection of the x-axis (the horizontal number line) and the y-axis in the cartesian system divides the coordinate plane into four equal pieces (the vertical number line).
