Answer:

its exponential because the parent function is y=(a)(b)^x

Step-by-step explanation:

Final answer:

The rule y = -3 ∙ 2ˣ defines an exponential function due to the term 2ˣ, where the base 2 is a constant raised to the variable power x, leading to a rapid change in y values as x changes.

Explanation:

The rule y = -3 ∙ 2ˣ represents an exponential function, not a linear function. In a linear function, the variable x is raised to the first power and appears in the form y = mx + b, where m and b are constants, and the graph is a straight line. In contrast, an exponential function is of the form y = a ∙ bˣ, where a and b are constants, and b is the base raised to the power of x.

The presence of the term 2ˣ indicates that as x increases, the value of y changes at an exponential rate. This is characterized by a curve that shows a rapid increase or decrease in value rather than a constant rate of change. Additionally, since the base b (which is 2 in this case) is a positive number other than 1, and it is raised to the power of x, this confirms the exponential nature of the function.

Answer:

60

Step-by-step explanation:

This question is super common sense which probably makes you

want to rethink the simple answer. Very plainly it says: Tuesday the Baker makes a total of 60 muffins. It doesn't tell us what "kind" of muffins they

are or are not. So then it asks how many "blueberry" muffins does the Baker bake on Tuesday.

They are only giving us one number that the Baker bakes on Tuesday and that number is 60

Answer:

The dimensions of the dilated rectangle are 30 cm x 16 cm

Step-by-step explanation:

we know that

To find the dimensions of the dilated rectangle, multiply the original dimensions by the scale factor

so

Let

A'B'C'D'------> the dilated rectangle

z-------> the scale factor

we have

z=2

A'B'=AB*z=15*2=30 cm

B'D'=BD*z=8*2=16 cm

The dimensions of the dilated rectangle are 30 cm x 16 cm

Step-by-step explanation:

Although the total cost depends on various factors, generally, owning a small dog tends to be more expensive than owning a cat, mostly due to additional expenses like training, grooming, and potential healthcare costs.

The question is about the average total cost difference between owning a cat and a small dog for a decade. This can be a complex calculation as different cost factors need to be considered, such as food, vaccinations, regular vet care, grooming etc. However, with the given information, we are unable to compute the exact difference. At this stage, a proper figure cannot be provided due to lack of the essential data about the yearly costs for each pet. However, on average, it is generally considered that owning a small dog can be more expensive than owning a cat due to additional expenses like training, grooming, and potentially higher healthcare costs.

Answer:

x = 20 feet, y = 40 feet

Step-by-step explanation:

See attached photo for solution

The length of the brick wall is 20 ft and the length of an adjacent side is 40 ft and this can be determined by forming the linear equation in two variables.

Given :

Let 'x' be the length of the brick wall and 'y' be the length of an adjacent side in feet. Then the area of the garden is:

xy = 800    --- (1)

The perimeter of the rectangular garden will be:

Perimeter = 24x + 8x +2(8)y    ---- (2)

Now, solve equation (1) for y.

[tex]y = \dfrac{800}{x}[/tex]   --- (3)

Now, put the value of 'y' in equation (2).

[tex]\rm P=32x+16\times \dfrac{800}{x}[/tex]

Now, for minimizing cost differentiate the perimeter with respect to 'x'.

[tex]\rm P'=32-16\times \dfrac{800}{x^2}[/tex]

Now, equate the above equation to zero.

[tex]0=32-16\times \dfrac{800}{x^2}[/tex]

[tex]\dfrac{800}{2}={x^2}[/tex]

x = 20

Now, put the value of 'x' in the equation (3).

[tex]y = \dfrac{800}{20}[/tex]

y = 40

Answer:

The correct answer is option 3

arc length = 7.5π

Step-by-step explanation:

It is given a circle with central angle ADC = 45° and radius = 30 cm

To find the length of arc ABC

From the figure we can see that the central angle of arc ABC = 45°

Therefore the arc length = (45/360) * Circumference

To find the circumference

Circumference = 2πr  = 2 * π * 30 = 60π

To find the arc length

Arc ABC  = (45/360) * 60π= 7.5π

Therefore arc length = 7.5π

The correct answer is option 3

Answer:

The graph of your question is attached in the picture below.

g(x) = 2^(-x)

Step-by-step explanation:

First of all, we use a graphing tool to plot each of the equations.

If we multiply in the plotter each graph, we can easily see which is the correct option.

h(x) =x+1

g(x) = 2^-x

Answer:

h(x)=-2^-x

Step-by-step explanation:

You can multiply both sides of an inequality by the same, nonzero number, but if this number is negative, you have to flip the sign.

In this case, in order to solve for x, you have to divide by -3 (i.e. multiply by -1/3), so yes, you must switch the sign:

[tex]-3x<15 \implies x>-5[/tex]

Alternatively, you may add 3x to both sides:

[tex]0<3x+15[/tex]

Subtract 15 from both sides:

[tex]3x>15[/tex]

And divide both sides by 3:

[tex]x>5[/tex]

The sign switch here was hidden behind the fact that we switched the two sides of the inequality

Find the Greatest Common Factor (GCF)

GCF = 4

Factor out the GCF. (Write the GCF first, then in parenthesis, divide each term by the GCF)

4(16w^4/4 + 16w^2/4 - 140/4)

Simplify each term in parenthesis

4(4w^4 + 4w^2 - 35)

Split the second term in 4w^4 + 4w^2 - 35 into two terms

4(4w^4 + 14w^2 - 10w^2 - 35)

Factor out common terms in the first two terms, then in the last two terms.

4(2w^2(2w^2 + 7) - 5(2w^2 + 7))

Factor out the common term 2w^2 + 7

= 4(2w^2 + 7)(2w^2 - 5)

Step-by-step explanation:

The surface area of the given solid will be the sum of areas of all of its sides. From the given figure we can see that the sides(faces) of the solid are:

The Area of each triangle is 4 square units. So we need to calculate the area of the squares.

Side length of square = 3 units

Area of square = Length² = 3² = 9

Surface Area of Given Solid = Area of 2 Triangles + Area of 3 Squares

= 2(4) + 3(9)

= 8 + 27

= 35 square units

Surface Area of Given Solid = 35 square units

Answer:

The surface area of the triangular prism is 35 square units

Step-by-step explanation:

It is given that,A solid is composed of squares and equilateral triangles

The area of each triangle is 4 square units

To find the surface area of solid

From the figure we get,

Surface area = Area of 2 triangle + area of 3 squares

There are 2 triangles with area = 4 square units

Area of 2 triangle = 2 * 4 = 8 square units

There are 3 squares with side = 3 units

Area of 1 square = 3 * 3 = 9 square units

Area of 3 squares = 3 * 9 = 27 square units

Surface area = 8 + 27 = 35 square units

The surface area of the triangular prism is 35 square units

Answer:

The standard form of the equation is y = 2x^2 + 16x + 25

Step-by-step explanation:

To find the standard form, first square the parenthesis.

y = 2(x + 4)^2 - 7

y = 2(x^2 + -8x + 16) - 7

Now distribute the 2

y = 2(x^2 + 8x + 16) - 7

y = 2x^2 + 16x + 32 - 7

Now combine like terms

y = 2x^2 + 16x + 32 - 7

y = 2x^2 + 16x + 25

Answer:

k = 10

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ZYM is an exterior angle of the triangle and

∠'s YZX and ZXY are the 2 opposite interior angles, hence

4k + 5 + 6k + 10 = 115

10k + 15 = 115 ( subtract 15 from both sides )

10k = 100 ( divide both sides by 10 )

k = 10

Answer:

k=10

Step-by-step explanation:

∠ZYX= 180-115= 65 these are supplementary angles adding up to 180°.

The interior angles in the triangle should add up to 180°

Adding the values and then equating to 180° we get the following equation.

65+(4k+5)+(6k+10)=180°

simplifying we get: 80+10k=180

10k=180-80

10k=100

k=10

Final answer is [tex]f(x)+g(x)=0.5x^2+8x^3[/tex]

Step-by-step explanation:

Given functions are [tex]f\left(x\right)=0.5x^2-2[/tex] and [tex]g(x)=8x^3+2[/tex]

Now we need to add both functions:

[tex]f(x)+g(x)[/tex]

[tex]=(0.5x^2-2)+(8x^3+2)[/tex]

[tex]=0.5x^2-2+8x^3+2[/tex]

[tex]=0.5x^2+8x^3-2+2[/tex]

combine like terms -2 and +2

[tex]=0.5x^2+8x^3[/tex]

Hence final answer is [tex]f(x)+g(x)=0.5x^2+8x^3[/tex]

Answer:

[tex] f ( x ) + g ( x ) = 8 x^3 + 0.5 x ^2 [/tex]

Step-by-step explanation:

We are given the following two functions and we are to find their sum:

[tex] f ( x ) = 0.5 x ^ 2 - 2 [/tex]

[tex] g ( x ) = 8 x ^ 3 + 2 [/tex]

Adding the two given functions to get:

[tex] f ( x ) + g ( x ) = 0.5 x ^ 2 - 2 + 8 x ^ 3 + 2 [/tex]

Rearranging them to solve further:

[tex]f(x)+g(x) =8x^3+0.5x^2+2-2[/tex]

So finally we get:

[tex]f(x)+g(x) =8x^3+0.5x^2[/tex]
