Why do all exponential functions go through 0 1?

Answer:

4 (8+r)

Step-by-step explanation:

The 4 (four) quadrants in order are: Quadrant I, Quadrant II, Quadrant III, and Quadrant IV.

A coordinate plane is divided into four sections called quadrants. These quadrants are numbered I, II, III, and IV in a counterclockwise direction, starting with the top right.

Quadrant I is the top right section of the coordinate plane, and it contains all the points where the x-coordinate and y-coordinate are positive.

Quadrant II is the top left section of the coordinate plane, and it contains all the points where the x-coordinate is negative and the y-coordinate is positive.

Quadrant III is the bottom left section of the coordinate plane, and it contains all the points where the x-coordinate and y-coordinate are negative.

Quadrant IV is the bottom right section of the coordinate plane, and it contains all the points where the x-coordinate is positive and the y-coordinate is negative.

Understanding this concept is important for solving mathematical problems, especially in algebra and geometry.

Answer: triangle 1's 1/2 length* triangle 1's width+triangle 2's 1/2 length* triangle 2's width+triangle 3's 1/2 length* triangle 3's width

Step-by-step explanation: triangle 1/2 length* triangle width=triangle area.

The length of the rectangle is 25 cm and the width is 10 cm.

We shall represent the length and width of the original rectangle with x and y respectively so that the perimeter is;

2(x + y) = 70 {divide through by 2}

x + y = 35...(1)

length of new rectangle = x - 5

width of new rectangle = y + 5

area of new rectangle:

(x - 5)(y + 5) = xy + 50

xy + 5x - 5y - 25 = xy + 50

xy - xy + 5x - 5y = 50 + 25

5x - 5y = 75 {divide through by 5}

x - y = 15...(2)

add equations (1) and (2) we have;

x + y + x - y = 35 + 15

2x = 50 {divide through by 2}

x = 25

substitute 25 for x in equation (1), we have;

25 + y = 35

y = 35 - 25 {subtract 25 from both sides}

y = 10

Therefore, have the length and width of the original rectangle to be x = 25 cm and y = 10 cm respectively.

Answer:

One glass of milk: 15 carbs

One snack bar: 13 carbs

Step-by-step explanation:

This problem is an example of systems of linear equations. We can set this problem up by defining variable. I used [tex]m[/tex] for the glass of milk and [tex]b[/tex] for the snack bar.

First, we have: 4 glasses of milk and 2 snacks bar have a total of 86 carbs. We can write this as

[tex]4m+2b=86[/tex]

Next: 2 glasses of milk and 3 snack bars have a total of 69 carbs.

We can write this as

[tex]2m+3b=69[/tex]

Now we set it up.

[tex]4m+2b=86[/tex]

[tex]2m+3b=69[/tex]

By dividing both sides of the first equation by 2, we can use the subtraction method to get rid of the variable [tex]m[/tex]. Now we have

[tex]2m+b=43[/tex]

[tex]2m+3b=69[/tex]

Subtract like terms and solve for [tex]b[/tex]

[tex]-2b=-26[/tex]

[tex]b=13[/tex]

Now we substitute [tex]b[/tex] back into the original equation to find [tex]m[/tex].

[tex]2m+(13)=43[/tex]

[tex]2m=30[/tex]

[tex]m=15[/tex]

Answer:3/8 was left over

Step-by-step explanation: 3/8 plus 1/4 x 2 equals  5/8... remainder 3/8

Answer:

3/8 (this is the answer)

The value of x in the given equation x² = 9 is x = ± 3.

In x² = 9, we need to remove the power of 2 in order to separate just x.

This implies finding the square root √x² which is equal to x.

However, there are 2 possible answers to any square root, a positive or a negative answer.

x = √9

x = ± 3

0r we can solve this equation by the splitting method.

Rearrange the equation

x² = 9

(x - 3)(x + 3) = 0

On solving, we get

x = +3 and x = -3

There are 2 types of images namely virtual and real image

The point where light rays from an object meet or appear to contact after reflection or refraction is sometimes referred to as the image. In this concept, a "object" might be anything that light rays are emanating from.

Real images and virtual images are the two types of images. The method by which they are created distinguishes a genuine image from a virtual image. Light beams must converge to create an actual image, whereas they must diverge to create a virtual image.

Real images are those that are created when light rays collide at a specific location after being reflected or refracted by a mirror or lens.

Virtual pictures are those that only seem to form when viewed from behind a mirror. Behind the mirror, the picture is not actually there. When light beams are refracted or reflected, a virtual picture is created.

Answer: To find the area that 1.6 litres of paint will cover, we can use the unit rate. The unit rate is a way to compare different quantities by finding how much of one quantity corresponds to one unit of another quantity.

We know that 750ml of paint covers an area of 12 m2, this means that the unit rate of paint:area is 750ml:12m^2

We can use this to find the area that 1.6 litres of paint will cover.

First we should convert the 1.6 litres of paint to milliliters, since we have the unit rate in ml:

1.6 litres = 1.6*1000 ml = 1600 ml

Now we can use the unit rate to find the area that 1.6 litres of paint will cover:

Area = (1600 ml paint) * (12 m2/750ml paint) = 21.333 m2

So, 1.6 litres of paint will cover approximately 21.333 m^2

Note that you could also use the proportion (750ml/12m^2) = (1600ml/x) to find the value of x.

So, the probability that the two biscuits are not the same type is 0.15 or 15%.

To find the probability that the two biscuits are not the same type, we need to calculate the probability that Sue takes one biscuit of each type.

First, we will calculate the probability that Sue takes one plain biscuit, one chocolate biscuit, and one currant biscuit.

The probability of Sue taking one plain biscuit is 12/20, since there are 12 plain biscuits out of a total of 20.

The probability of Sue taking one chocolate biscuit after taking a plain biscuit is 5/19, since there are now 5 chocolate biscuits out of 19 remaining.

The probability of Sue taking one currant biscuit after taking a plain and chocolate biscuit is 3/18, since there are now 3 currant biscuits out of 18 remaining.

To find the overall probability that Sue takes one biscuit of each type, we multiply the individual probabilities together:

P = (12/20) * (5/19) * (3/18) = 0.15

So, the probability that the two biscuits are not the same type is 0.15 or 15%.

The equation of the line passing through the point (-6, 5) and (8, -2) in point-slope form is y - 5 = -0.5(x + 6).

The point-slope form of a line is

y - y1 = m(x - x1)

where (x1, y1) is a point on the line, and m is the slope of the line.

To find the equation of a line given two points, we can use either point and find the slope of the line using the formula:

m = (y2 - y1) / (x2 - x1)

So, we can use the point (-6, 5) and (8, -2)

m = (y2 - y1) / (x2 - x1) = (-2 - 5) / (8 - (-6))

m = -7/14

m = -1/2

Now we can use this slope and the point (–6,5) to find the equation of the line in point-slope form:

Answer:

Use direct variation method of mathematics

The range of a function is the set of all possible outputs (y-values) for a given input (x-value).

Given the function f(x) = [x+3]-5, we can see that the function first adds 3 to x and then subtracts 5. The square bracket notation around (x+3) indicates that the function is taking the greatest integer less than or equal to (x+3).

For any input x, the output of the function will always be the greatest integer less than or equal to (x+3) - 5. Therefore, the output of the function is always an integer less than or equal to -2.

So the range of the function is [-5, -2] U (-2, ∞)

Option A) [-5,∞) is incorrect as the range starts with -5 but the function output is always less than or equal to -2.

Option B) (-5,∞) is incorrect as the function output is always less than or equal to -2.

Option C) [3,∞) is incorrect as the function output is always less than or equal to -2.

Option D) (3,∞) is incorrect as the function output is always less than or equal to -2.
