Answer:

14 square units

Step-by-step explanation:

There are several ways we can find the area.  Probably the easiest is to cut the kite in half vertically and find the area of each triangle.  The area of the kite will be double that.

The height of the kite is 7 units, and the width is 4 units.  So each triangle will have a base of 7 and height of 2.

A = 1/2 bh

A = 1/2 (7) (2)

A = 7

The area of the kite is double that, so:

2A = 14

The area of kite WXYZ in the coordinate plane given is: C. 14 square units.

Area of a kite = pq/2, where p and q are the diagonal lengths of the kite.

The dimensions of the kite are:

Area of the kite = (7×4)/2

Area of the kite = 14 square units

Answer:

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

Step-by-step explanation:

Here we are given with parent function [tex]f(x)=2^x[/tex] and the graph which shows that the function g(x).

We are asked to guess the function g(x).

We are given the two coordinates on g(x)

(0,8) and (2,32)

Hence for x = 0 , g(x)= 8

And for x=2, g(x)= 32

Let us say that the translated function is represented by

[tex]g(x)=a2^x+b[/tex]

[tex]g(0)=a\times 2^0+b[/tex]

Hence

[tex]a \times 2^0+b=8[/tex]

[tex]a +b=8[/tex] --------------- (i)

also

[tex]g(2)=32[/tex]

Hence

[tex]a\times 2^2+b=32[/tex]

[tex]4a+b=32[/tex] -------------------(ii)

Subtracting (i) from (ii) we get

[tex]3a=34[/tex]

Hence a = 8

Now putting this value of a in (i)

[tex]8+b=8[/tex]

B=0

Hence [tex]g(x)=8 \times 2^x +0[/tex]

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

In Euclidean Geometry, a function refers to a mathematical expression which is used for defining and representing the relationship that exists between two or more variables such as an ordered pair.

This ultimately implies that, a function is typically used in mathematics for uniquely mapping an input variable (Set P) to an output variable (Set Q).

In this context, we can logically deduce that table D does not represent a function because the same input value is mapped to different output values;

The surface area of the pyramid is the area of the four triangular faces plus the area of the square base.

The area of the four triangular faces is

Answer:

  B.  1/392 cubic yard

Step-by-step explanation:

The volume is the product of base area and height:

  V = Bh = (1/28 yd²)·(1/14 yd) = 1/(28·14) yd³ = 1/392 yd³

Answer:

B. 1/392 cubic yard

Step-by-step explanation:

Given,

The base area of the pillar, B = [tex]\frac{1}{28}[/tex] square yard ,

Its height, h = [tex]\frac{1}{14}[/tex] yd

Thus, the volume of the pillar would be,

[tex]V=B\times h[/tex]

[tex]=\frac{1}{28}\times \frac{1}{14}[/tex]

[tex]=\frac{1}{28\times 14}[/tex]

[tex]=\frac{1}{392}\text{ square yard}[/tex]

Since, the concrete he needs to cast the pillar = Volume of the pillar

= [tex]\frac{1}{392}\text{ square yard}[/tex]

Option 'B' is correct.

For this case we have to:

Lewis carries 2 liters of water

Garret carries 1 liter of water

So, Lewis has 1 liter of water more than Garret.

By definition we have that 1 liter equals 1000 milliliters.

Thus, Lewis carries 1000 milliliters more water than Garret.

Answer:

1000 milliliters

Answer:

y = -x + 2

Step-by-step explanation:

We first need to find the derivative of the equation x² + xy + y² = 3. this is done with implicit differentiation

2x + y + xy' + 2yy' = 0

Get terms with y' to one side, and the other terms to the other side of the equals sign...

xy' + 2yy' = -2x - y

Factor out y'...

y'(x + 2y) = -2x - y

Divide both sides by x + 2y

y' = (-2x - y)/(x + 2y)

This is the formula for the slope of the lines tangent to the curve of the original function.

Plug in the given point (1, 1) to find the slope of this

y' = (-2[1] - 1)/(1 + 2([1])

y' = -3/3

y' = -1

To find the equation of the line:

The general form for a linear equation in slope-intercept form is  

y = mx + b where m is the slope and b is the y-intercept

Use what we know about our line to solve the rest. By using one of the given points, we have 3 of the 4 variables in the above equation. Pick either point, it doesn't matter which one. We'll use (1, 1), which is (x, y), and we know that  

m = -1

The equation becomes...

1 = -1(1) + b (now solve for b)

1 = -1 + b

2 = b  

Plug that value into the general form...

y = -x + 2

See attached photo for the graphs of the original equation, and the graph of the tangent line at (1, 1)

ANSWER

[tex]p = - 2[/tex]

EXPLANATION

The given equation is

[tex]x = - \frac{1}{8}{y}^{2} [/tex]

Multiply both sides by -8

[tex] \implies \: {y}^{2} = - 8x[/tex]

We now compare this to the general equation of the parabola:

[tex] {y}^{2} = 4px[/tex]

This implies that,

[tex]4p = - 8[/tex]

Divide both sides by 4.

[tex]p = \frac{ - 8}{4} [/tex]

[tex]p = - 2[/tex]

Answer:

Step-by-step explanation:

-8 + 6(b - 1) =  -8 +6b-6 = 6b -14

The simplified expression is now 6b - 14.

To simplify the expression -8 + 6(b - 1), you need to distribute the 6 to both terms inside the parentheses and then combine like terms. Here's the step-by-step process:

Multiply 6 by both b and -1 inside the parentheses: 6 * b gives 6b, and 6 * -1 gives -6.

Write out the new expression without the parentheses: -8 + 6b - 6.

Combine the like terms, which are the constants -8 and -6: -8 - 6 equals -14.

The simplified expression is now 6b - 14.

Answer:

Step-by-step explanation:

The formula for the volume of a cone is V = (1/3)(area of base)(height).  If the radius is always equal to the height of the cone, then V = (1/3)(πh²)(h), where we have eliminated r.  Shortened, this comes out to V = (1/3)(π)(h³).  

We want to know how fast h is increasing when h = 3 ft.

Taking the derivative dV/dt, we get dV/dt = (1/3)π(3h²)(dh/dt), or, in simpler terms, dV/dt = πh²(dh/dt).  Set this derivative = to 27 ft³/min and set h = 3 ft.

Then 27 ft³/min = π(3 ft)²(dh/dt) and solve for dh/dt:  (3/π) ft/min = dh/dt when h = 3 ft.

Answer: hey, the answer will be choice number 2 or b

Step-by-step explanation:

For this case we have that, by definition, the volume of a cylinder is given by the following formula:

[tex]V = \pi * r ^ 2 * h[/tex]

Where do we have to:

A: It's the radio

h: It's the height

We have to:

[tex]h = 3\\r = 8[/tex]

Substituting the values we have:

[tex]V = \pi * (8) ^ 2 * 3\\V = \pi * 64 * 3\\V = 192 \pi \ units ^ 3[/tex]

Step-by-step explanation:

Let

x----> number of sweets that Dan has

y----> number of sweets that Gordon has

z----> number of sweets that Malachy has

we know that

x=48

x/y=4/3----> y/x=3/4 ----> y=(3/4)x

Substitute the value of x

y=(3/4)48=36

x/z=4/5 ----> z/x=5/4 ----> z=(5/4)x

Substitute the value of x

z=(5/4)48=60

therefore

altogether there are  x+y+z=48+36+60=144 sweets

In this case they tell us that the opposite side measures 4 inches and the angle x measures 80 °.

With this information we can find the length of the hypotenuse h

The value of Kayleigh's investment in 7 years is approximately $930.05.

To find the value of Kayleigh's investment in 7 years, we can use the given equation A = d(1.005)^12t. Let's substitute the values: d = $850, t = 7.

Plugging in these values, we have A = 850(1.005)^(12*7).

Evaluating the expression, the value is approximately $930.05 when rounded to the nearest cent.

This implies that Kayleigh's initial investment of $850, compounded monthly at a rate of 0.5%, will grow to around $930.05 after 7 years.
