What is the value of 6x2 – 4x when x = 5?
Final answer:
To calculate 6x^2 – 4x when x = 5, you square 5 to get 25, multiply by 6 to get 150, then subtract 4 times 5 which is 20, resulting in a final value of 130.
Explanation:
To find the value of the expression 6x^2 – 4x when x = 5, you need to substitute 5 for x in the expression and perform the arithmetic. First, calculate the value of 6x^2 by squaring x (which is 5) and multiplying by 6:
6 * 5^2 = 6 * 25 = 150.
Next, calculate the value of 4x when x is 5:
4 * 5 = 20.
Now subtract the result of 4x from the result of 6x^2:
150 - 20 = 130.
So, the value of the expression when x = 5 is 130.

what is the limit as x approaches negative infinity of (1.001)^x ...?
The limit as x approaches negative infinity of (1.001)^x is 0, because as we raise a number slightly larger than 1 to increasingly negative exponents, the results get closer and closer to zero.
The student is asking about the limit of a function as x approaches negative infinity, specifically for the function (1.001)^x. When evaluating this limit, it is essential to understand how exponential functions behave as the exponent becomes very large or very negative. Since 1.001 is greater than 1, raising it to increasingly negative exponents will result in values that approach zero. Therefore, the limit as x approaches negative infinity of (1.001)^x is 0.
Understanding the behavior of functions at infinity can be connected to the general concept where, for example, the reciprocal of a number as it approaches zero from the positive side (1/x) goes to positive infinity and from the negative side (1/x) goes to negative infinity. However, when evaluating the limit at negative infinity for our function, we must consider the base of the exponential function, which dictates that the function's values descend towards zero.
a bowling ball weighs 48 N. With what net force must it be pushed to accelerate it at 3.0 m/s2
Final answer:
The net force required to accelerate a bowling ball weighing 48 N at 3.0 m/s² is 14.7 N, which we round to 15 N using two significant figures.
Explanation:
To find the net force required to accelerate the bowling ball at 3.0 m/s², we can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). First, we need to determine the mass of the bowling ball. Since the weight of the bowling ball is given as 48 N and weight can be calculated by multiplying mass with the acceleration due to gravity (weight = mass × gravity), we can find the mass (m = weight / gravity). Assuming the acceleration due to gravity is 9.8 m/s², the mass of the bowling ball would be approximately 4.9 kg (48 N / 9.8 m/s²). Next, we apply Newton's second law to find the net force required for the 3.0 m/s² acceleration by multiplying the mass by the desired acceleration (F = ma).
The calculation is as follows:
F = ma = 4.9 kg × 3.0 m/s² = 14.7 N
Therefore, a net force of 14.7 N must be applied to the bowling ball to achieve the acceleration of 3.0 m/s². We typically round this to two significant figures, giving a final answer of 15 N.

The standard form of the equation of a parabola is x = y2 + 10y + 22. What is the vertex form of the equation?
Answer:
The vertex form of the parabola is [tex]x=(y+5)^2-3[/tex]
C is the correct option.
Step-by-step explanation:
The standard form of the parabola is [tex]x=y^2+10y+22[/tex]
We can write this equation in vertex form by using the completing square method.
For the expression [tex]y^2+10y[/tex], the value of b is 10.
Hence, add and subtract [tex](\frac{10}{2})^2=25[/tex] to the right side of the equation.
Thus, the equation becomes
[tex]x=y^2+10y+25-25+22[/tex]
Now, the expression [tex]y^2+10y+25=(y+5)^2[/tex]
Hence, we have
[tex]x=(y+5)^2-25+22[/tex]
We can simplify further as
[tex]x=(y+5)^2-3[/tex]
Hence, the vertex form of the parabola is [tex]x=(y+5)^2-3[/tex]

Jane sells 8 times as many Volvos as Melissa. If the difference in their sales is 35, how many cars did Jane sell?
Melissa sold 5 Volvos. Given that Jane sold eight times as many Volvos as Melissa, Jane sold 40 Volvos.
Explanation:In order to solve this problem, we can use a simple equation. Let's denote the number of Volvos Melissa sold as 'x'. Since Jane sells 8 times as many Volvos as Melissa, the number of Volvos Jane sold can be denoted as '8x'. We know from the problem that the difference between the number of cars Jane and Melissa sold is 35, so we can write the equation like this: 8x - x = 35.
By simplifying the equation, we get 7x = 35. Therefore, to find the value of 'x', we divide 35 by 7, which gives us 'x' equals to 5.
But 'x' is the number of Volvos Melissa sold. To find out the number of cars Jane sold, we multiply 'x' by 8. Which gives us 5 multiplied by 8 equals to 40 cars.

Find the equation of a line that satisfies the given conditions; x-intercept = 2, and y-intercept = -8
The equation of a line with an x-intercept of 2 and a y-intercept of -8 is y = 4x - 8, which follows from applying the slope-intercept form and calculating the slope based on the intercepts.
To find the equation of a line with an x-intercept of 2 and a y-intercept of -8, we use the slope-intercept form of a line, which is y = mx + b, where m is the slope and b is the y-intercept.
We can determine the slope by recognizing that the line crosses the x-axis at (2,0) and the y-axis at (0,-8).
The slope m is the rise over the run, which in this case is (-8 - 0) / (0 - 2) = 4.
Therefore, the equation of the line is y = 4x - 8.
This equation satisfies the given conditions, as plugging in x = 0 gives the y-intercept of -8 and setting y to 0, and solving for x yields the x-intercept of 2.

Jessica gets her favorite shade of purple paint by mixing 1/3 cup of blue paint with 1/2 cup of red paint. How many cups of blue and red paint does Jessica need to make 20 cups of her favorite purple paint?
To make 20 cups of Jessica's favorite purple paint, she needs approximately 6.67 cups of blue paint and 10 cups of red paint.
Explanation:To find the number of cups of blue and red paint Jessica needs to make 20 cups of her favorite purple paint, we need to set up a proportion based on the ratios of blue paint and red paint in her favorite shade.
Since Jessica uses 1/3 cup of blue paint and 1/2 cup of red paint to make her favorite shade, we can set up the proportion:
1/3 cup of blue paint / 1/2 cup of red paint = x cups of blue paint / 20 cups of purple paint.
To solve for x, we can cross multiply and divide:
x = (1/3 cup of blue paint)(20 cups of purple paint) / (1/2 cup of red paint) = 20/3 = 6.67 cups of blue paint.
So, Jessica needs approximately 6.67 cups of blue paint and 10 cups of red paint to make 20 cups of her favorite purple paint.

Step-by-step explanation:
A Perfect Cube is an integer number multiple of three that can be expressed as a product of prime factors raised to 3rd power. We have many Perfect Cubes, such as:
15³=3³x5³, and 15 ∈ ={1,3,6,9,12,15,18,..} so 15 is a perfect cube
18³=2³x3³x3³ and 18 ∈ ={1,3,6,9,12,15,18,..} so 18 is a perfect cube.
Finally, for instance, we can rewrite the number 373248 as
