If g(x) = -2x² + 3x - 1, find g(x + 1)

Answers

The value of the equation g(x+1) is -2x²-x

Given equation,

g(x) = -2x²+3x-1

Replacing x in the equation by x+1

g(x+1) = -2(x+1)² +3(x+1) -1

g(x+1) = -2(x²+1+2x) +3x +3 -1

g(x+1) = -2x² -2 -4x +3x +3 -1

g(x+1) = -2x²- x

Hence the final answer is g(x+1) = -2x²-x

Since this, the question says to find the value g(x+1) we need to replace the value of x in the given equation g(x) by x+1 to find value. After replacing we get -2(x+1)² +3(x+1) -1. Next, we need to solve the bracket (x+1)² which will give us x²+1+2x. We will multiply this by -2, which will give us -2x² -2 - 4x. Next, we will solve 3(x+1) which will give us 3x+3. Finally, we need to solve the whole equation to get the answer -2x²- x

What is  probability ?

The probability of an event is given by dividing the favorable outcomes by total number of outcomes. The sum of all the probabilities of events is always 1. If for finding probability we have to select r out of n. Combination is used to select r items out of n, the formula is as follows,

[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]

Finding the probability that 2 red cards and 11 black cards are dealt,

Number of favorable outcomes will be [tex]^{26}C_2\times^{26}C_{11}[/tex].

Total number of outcomes will be [tex]^{52}C_{13}[/tex]

What is the equation of the line that passes through the point (7,4) and has a slope of 1?

Answers

Answer:

y = x - 3

Step-by-step explanation:

Consider the equation "y = mx + b" :

y = mx + b

Since the slope is 1, you could input that into the equation:

y = (1)x + b

The variable "b" represents the y-intercept, therefore, to find the y - intercept, you would have to subtract 7 from each side of the coordinate points to get 0 as the x - coordinate to find the y - intercept:

(7    4)

-7 || -7

(0, -3)

Therefore, the y - intercept would be -3 and the equation would be:

Bass Guitar Notes:

Answers

Yes, the two quantities have a proportional relationship because the variables x and y all have the same constant of proportionality.

What is a proportional relationship?

Mathematically, a proportional relationship can be represented or modeled with the following mathematical expression:

y = kx

Where:

y represents the numbers of bass guitar notes.x represents the numbers of snare drum backbeats.k represents the constant of proportionality.

In order for the two quantities to have a proportional relationship, the variables x and y must remain in a constant ratio.

Next, we would determine the constant of proportionality (k) as follows:

Constant of proportionality (k) = y/x

Constant of proportionality (k) = 2/3

When x = 90 and y = 60, we have:

Constant of proportionality (k) = 60/90

Constant of proportionality (k) = 2/3

When x = 120 and y = 80, we have:

Constant of proportionality (k) = 80/120

Constant of proportionality (k) = 2/3

Omar was out at a restaurant for dinner when the bill came. He wanted to leave a tip
of 34%. What number should he multiply the cost of the meal by to find the total plus tip in one step?

Answers

Answer:

Note: A percentage is always a number over 100.      (34% = [tex]\frac{34}{100}[/tex])

Cost of meal = 100%

Cost of tip = 34%

Total = 134%

134% = [tex]\frac{134}{100}[/tex]

To find the total and the tip, you must multiply it by [tex]\frac{134}{100}[/tex]

Answer:

Bill times the 0.34 percent equals the price of the tip. After you find what the tip is, you add the base price (the bill price) to the tip and you get the total number paid. However, another way you can solve (in one step) this is by adding 1.00 to the percent you are multiplying by which in this case we add 0.34 by 1.00 and this gives us 1.34. Suppose we set the bill to 4 dollars and use the normal way (2-step equation) by doing 3(0.34) which is 1.02 and 1.02 + 3 = 4.02 as our final answer / final bill. However, when we do our one-step equation, we can write this as 3x(1.34) and this is equal to 4.02.

1st Step

Bill(0.34) = tip

tip + bill = total

2nd Step (one-step equation)

Note: we are going to set the bill in this equation as $4

4(1.34) = total; Total = 4.02 ← We added 1.00 to the tip percentage in decimal form.

if the average *arithmetic mean) of 5,6,7 and w is 10 what is the value of w

Answers

Using the properties of arithmetic mean and average we get the value of 'w' is 22.

We know that mean is calculated by dividing the sum by the frequency.

Here n= 3

Sum = 5+6+7+w = 18+w

Now , (18+w )/4 = 10 which is the mean

or, 18 + w = 40

or, w = 40 - 18

or, w = 22

The value of w is 22.

By adding together all the observations and then dividing the sum by the same total sample sizes, the arithmetic mean of the supplied data can be calculated.

Similar to how you discovered linear and quadratic models in prior chapters, exponential models can be found by fitting data to them. As you may already be aware, exponential functions take the form y = abx, where an is the value of y at x = 0 and b is the growth factor over each unit of time. Based on an equation like this one, the exponential model represents the degradation failure process: Y = deterioration; T = time; A and B = parameters to be calculated using the regression approach based on historical data. An expansion within a population that happens at the same pace across time is represented by the function of exponential growth. It is reasonable to suppose that data grows exponentially as populations double or triple in size.

What is linear equation?

A linear equation is one in which the variable's maximum power is consistently 1. A one-degree equation is another name for it. A linear equation with one variable has the formula Ax + B = 0, which is its standard form. x is a variable, A is a coefficient, and B is constant in this situation. A linear equation with two variables has the formula Ax + By = C as its standard form. Here, the variables are x and y, the coefficients are A and B, and the constant is C.

Consider, the first equation

y = 2^2

⇒ y = 4

Since, the constant equations are linear.

So, first equation is linear.

Consider, second equation

y = 2x - 5

Here, the variable x and y both having degree 1.

So, second equation is also linear.

Consider, third equation

y = x^2 + 6

What is the length of the base edge?
The length of the base edge of the pyramid is …

Answers

The length of the base edge of the given square pyramid is 3.67 feet.

What is the Surface Area?

The sum of all an item's faces makes up the surface area of a three-dimensional object. When wrapping, painting, and finally creating things to get the finest possible design, we apply the idea of surface areas of various items in real life.

What is a Square Pyramid?

In geometry, a pyramid with a square base and four lateral sides is referred to as a square pyramid.A polyhedron with a base and three or more triangle faces that meet above the base is called a pyramid (the apex). A pentahedron is a three-dimensional structure with a total of five faces, such as a square pyramid. The Great Pyramid of Giza is one of the most well-known examples of a pyramid like this in real life.

Steps to Calculate the Base Edge Length of Square Pyramid

The formula for surface area of square pyramid is given by, [tex]SA=a^{2} +2a\sqrt{\frac{a^{2} }{4}+h^{2} }[/tex],    -----(1)

where [tex]a[/tex] is the length of the base edge and [tex]h[/tex] is the square pyramid height.

In the question, it is given that the surface area of the square pyramid is 96 square feet.

The height of the square pyramid is two-thirds of the base edge length.

[tex]\implies h=\frac{2a}{3}[/tex]  ------(2)

Now substituting the given values in (1), we get

[tex]96=a^{2} +2a\sqrt{\frac{a^{2} }{4}+(\frac{2a}{3} )^{2} }\\\implies 96=a^{2} +2a\sqrt{\frac{a^{2} }{4}+\frac{4a^{2} }{9} }[/tex]

Simplifying, we get

[tex]96=a^{2} +2a\times 0.834a^{2} \\\implies 96=a^{2} +1.668a^{3} \\\implies 1.668a^{3}+a^{2} -96=0[/tex]

Finally, we get the value of [tex]a=3.67[/tex] feet.

Therefore, the base edge length of the given square pyramid is 3.67 feet.

12.4% converts to the decimal form 0.124

Optionally you could use your calculator to say 12.4/100 = 0.124

--------

To convert from a terminating decimal to a fraction, we write the decimal digits over some power of 10. In this case, we write the "124" over 10^3 aka 1000. We write it over 1000 since the '4' is in the thousandths place value. Then reduce as much as possible.

What we need to do is isolate a on one side of the equal side. Now, remember that multiplication and division cancel each other out, so if we divide b and d on the right side by b and d then we cancel those values and get a by itself. Now, we have to do this on the left side as well in order to keep the equation balanced. When we do this, we get c/bd = a. Keep working hard! You're doing great!
