given f(x)= -x^2+2x+6, find f(-7)

The expected value of the game is $16.50.

First we need to multiply the amount you can win by the probability of winning it, then add up all the products.

Let's call the expected value "E":

E = (0.20 x $60) + (0.15 x $30) + (0.25 x $0) + (0.40 x $0)

E = $12 + $4.50 + $0 + $0

E = $16.50

Therefore, the expected value of the game is $16.50.

Answer: 56

Step-by-step explanation: Since we know both triangles are similar, we want to first find the scale factor between the two triangles, knowing side UP and side PQ are corresponding we can find that 84/60 or in simplified terms, 7/5 is the scale factor. Now we know that side VP and side PR are corresponding so 40 x 7/5 gives us 56 which is side PR. Hope this helped! :)

The domain of the equation y = -16x^2 + 1700 is the set of all real numbers.

To find the domain of the equation y = -16x^2 + 1700, we need to determine the set of all real numbers for which the equation is defined.

Since the equation is a quadratic equation, it is defined for all real values of x. There are no restrictions on the values of x that can be plugged into the equation.

Therefore, the domain of the equation y = -16x^2 + 1700 is the set of all the real numbers.

The distance between two points in a coordinate plane can be found by the formula d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

To calculate the distance between two points in a coordinate plane, you can use the distance formula:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points, and d is the distance between them.

For example, if you want to find the distance between the points (2, 3) and (5, 7), you would plug in the values as follows:

d = sqrt((5 - 2)^2 + (7 - 3)^2)

d = sqrt(3^2 + 4^2)

d = sqrt(9 + 16)

d = sqrt(25)

d = 5

Therefore, the distance between two points is d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

The probability that a continuous random variable will be equal to any specific value is zero. This is because the probability of an individual value for a continuous random variable is represented by the area under the probability density function (PDF) at that particular value, and the area of a single point is zero.

We can convert fps to mph by using the relation, one mph = 1.18 fps.

One fps means one foot per second and one mph means one mile per hour. Foot and mile are the units of distance and second and hour are the units or time.

We have to convert fps to mph.

As per the standard unit conversion rates, we know,

One mile = 5280 foot.

Also, one hour = 3600 seconds.

So, if we want to convert, we should write,

= mph

= 4280/3600

= 1.18 fps.

The expression f - 5(2f – 3) is equivalent to two other expressions, option (a) -11f-3 and option (b) -11f + 15.

In mathematics, an expression is a combination of symbols, operated on by certain mathematical operations to create a numerical value or a function.

To understand why this is the case, let's break down the expression.

The first part of the expression is just the variable f, so that is unchanged. The second part involves the multiplication of -5 and (2f – 3).

To evaluate this part, we need to use the order of operations. First, we multiply -5 and 2f and get -10f.

Then, we subtract 3 from this result and get -11f.

Therefore, the expression f - 5(2f – 3) is equivalent to -11f-3 and -11f + 15.

The step which is used is to construct the altitude from the incentre  to a side of triangle and label the intersection point.

Step-by-step explanation:

Given point d is is the center of inscribed circle.

To construct the inscribed circle of abc we have several steps of construction

Step 1: First step is to construct the incenter with the help of angle bisectors of two base vertices.

Here given d center of inscribed circle that means the incenter given.

Step 2: After incenter, draw a line perpendicular to one side of triangle that passes through incenter and the label the point of intersection.

This is very important step because after labelling measure the radius(same as the distance between the incenter and labelled point) and draw the circle.  

Hence, after incenter The next step is to construct the altitude from the incentre  to a side of triangle and label the intersection point.

Step 2 is used draw inscribed circle when incenter already given.

A linear equation is an algebraic equation of the form y = mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given, a linear equation that passes through the points (5,0) and (0, -7)

The slope-intercept form of the equation of a line

y=mx+b,

where m is the slope

b is the y-intercept

since, slope = (y - y')/(x -x')

In our case,

slope = (-7 -0)/(0-5)

slope = 7/5

b = -7

thus,

the equation of the line will be:

y = 7/5x -7

multiply by 5 on both sides

5y = 7x -7

1.5 kilograms of eggs is equivalent to approximately 3.31 pounds. Both kilograms and pounds are weight measuring units.

To convert kilograms to pounds, we can use the conversion factor that 1 kilogram is equal to 2.20462 pounds.

So to convert 1.5 kilograms of eggs to pounds, we can multiply 1.5 by 2.20462:

1.5 kilograms x 2.20462 pounds/kilogram = 3.30693 pounds

Therefore, 1.5 kilograms of eggs is equivalent to approximately 3.31 pounds. Both kilograms and pounds are weight measuring units. Kilograms are the primary unit of measurement for weight in the International System of Units (SI), while pounds are the primary unit of measurement for weight in the United States and other countries that use the imperial system of units. A kilogram is roughly equivalent to 2.20462 pounds.
