Answer:

  261 in²

Step-by-step explanation:

The surface area of a square pyramid can be found from the formula ...

  A = s(s +2h)

where s is the side length of the base and h is the slant height of a face.

__

For s = 9 in, and h = 10 in, the surface area is ...

  A = (9 in)(9 in +2×10 in) = (9·29) in² = 261 in²

The surface area of the square pyramid is 261 square inches.

Answer:

$172,984.44

Step-by-step explanation:

We can use the formula

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex] to compute the final amount

Here P is the principal amount, the original deposit = $25,000

r is the annual interest rate = 6.5% = 0.065 in decimal

n is the number of times the compounding takes place. Here it is quarterly so it is 4 times a year

t is the number of time periods ie 30 years

A is the accrued amount ie principal + interest

Computing different components,

[tex]nt = 4 \times 30 = 120[/tex]

[tex]r/n = 0.065/4 = .01625[/tex]

[tex]1 + r/n = 1.01625[/tex]

[tex](1 + r/n)^{nt} = 1.01625^{120}[/tex]

Therefore

[tex]A = 25000 \times 1.0625^{120} = 172,984.44[/tex]

Answer:

p(x) = 500(1.02)^x

Step-by-step explanation:

I took the test and got a 100.

The exponential function is p(x) = 500(1.02)×, option (D) is correct.

It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent [tex]y = a^x[/tex]

where a is a constant and a>1

We have the functions given in the options:

As we know the standard form of the exponential function is:

f(x) = a(b)×

The exponential function will increase or decrease exponentially.

From the option:

p(x) = 500(1.02)×

p(x) is an exponential function.

Thus, the exponential function is p(x) = 500(1.02)×, option (D) is correct.

Answer:

  (a)  46°

  (b)  86°

Step-by-step explanation:

When the secants cross externally (figure a), the angle where they cross is half the difference of the subtended arcs.

When they cross internally (figure b), the angle is half the sum of the subtended arcs.

__

Half the difference of arcs VW and VX is ...

  ∠VYW = 1/2(160° -68°) = 46°

  m∠VYW = 46°

__

Half the sum of arcs AB and CD is ...

  ∠CED = 1/2(arc AB +arc CD)

  2×∠CED = arc AB +arc CD . . . . . multiply by 2

  2×∠CED -arc AB = arc CD . . . . . subtract arc AB

  arc CD = 2×85° -84° = 86°

  m arc CD = 86°

Answer:

585 m^2.

Step-by-step explanation:

Surface area = area of base + 4 * area of a triangular side

= 13^2 + 4 * 1/2 * 13 * 16

= 169 + 26 * 16

= 585

Answer:

585 m²

Step-by-step explanation:

The surface area of the given pyramid is made up of 4 congruent triangles and a square base.

Area of a triangle = 1/2 × base × height

                             = 1/2 × 13 × 16

                             = 104 m²

Area of a square = (base edge)²

                            = 13²

                            = 169 m²

Total Surface Area = area of 4 triangles + area of base square

                               = (4 × 104) + 169

                               = 416 + 169

                               = 585 m²

Answer:

Option (C)

Step-by-step explanation:

Domain of function is defined by the set of x-values (input values) and Range of a function is a set of y-values (output values).

From the graph attached,

Domain of f(x) → Set of all real numbers

Range of f(x) → y-values > 0

Domain of [tex]y > 0[/tex] → Set of all real numbers

Range of [tex]y > 0[/tex] → y < 2

Therefore, domain of both the functions is a set of all real numbers.

Option (C) is the correct option.

The Area of Piece of Land is  = 150 +[tex]24\sqrt{11}[/tex]  squared yards

The area of a trapezium can be calculated using the lengths of two of its parallel sides and the distance (height) between them.

As the yard is in shape of Trapezium.

We have to find the area of trapezium.

Area of piece of property = Area of Triangle +  Area of rectangle + Area of Triangle

Area of Triangle I,

base = [tex]\sqrt{(13)^{2}{-(12)^{2}}[/tex] = [tex]\sqrt{169-144}[/tex]= 5yds

Area = [tex]\frac{1}{2}*b*h[/tex]

        =0.5 x 5 x 12

       = 30 squared yds

Area of rectangle = length x breadth

                             = 10 x 12

                             = 120 squared yds

Area if Triangle II, base = [tex]\sqrt{(15)^{2}{-(7)^{2}}[/tex]= [tex]\sqrt{225-49}[/tex]= [tex]4\sqrt{11}[/tex]

Area= [tex]\frac{1}{2}*b*h[/tex]

        =0.5 x [tex]4\sqrt{11}[/tex]  x 12

        = [tex]24\sqrt{11}[/tex] squared yds

Area of piece of land = 30 + 120 + [tex]24\sqrt{11}[/tex]

                                    = 150 +[tex]24\sqrt{11}[/tex] squared yards

Hence, the area of piece of land= 150 +[tex]24\sqrt{11}[/tex]  squared yards

Answer:

No, it is not a right triangle.

Step-by-step explanation:

Let's take it as,

→ Hypotenuse = 28 mm

→ Perpendicular = 25 mm

→ Base = 10 mm

Now use Pythagoras theorem,

→ Hypotenuse² = Perpendicular² + Base²

→ 28² = 25² + 10²

→ 784 = 625 + 100

→ 784 ≠ 725

→ [ LHS ≠ RHS ]

Hence, it does not forms a right triangle.

Vertex: (0,-3)

Radius: 4

Step-by-step explanation:

Complete the square

[tex]x^2+y^2+6y=7\\\\x^2+y^2+6y+9=7+9\\\\x^2+(y+3)^2=16[/tex]

The equation of a circle takes the form of [tex](x-h)^2+(y-k)^2=r^2[/tex] where its center is [tex](h,k)[/tex] and its radius is [tex]r[/tex].

Hence, the vertex is [tex](0,-3)[/tex] and the radius is [tex]4[/tex].

Step-by-step explanation:

The unit circle is a circle in the form of

[tex] {x}^{2} + {y}^{2} = 1[/tex]

while x = cos t

y= sin t

, where t is an angle

So we plug in -1/7, for x to find y

[tex]( \frac{ - 1}{7} ) {}^{2} + {y}^{2} = 1[/tex]

[tex] {y}^{2} = \frac{49}{49} - \frac{1}{49} [/tex]

[tex]y = \frac{4 \sqrt{3} }{7} [/tex]

If the point is in the 2nd quadrant, your value of y is positive

If it in the third quadrant, the y value is negative

Answer:

y= -2x........eqn i

y=5x+3......eqn ii

substituting the value of Y from eqn i in eqn ii, we get,

-2x=5x+3

-7x=3

x= -3/7

so, y= -2x= -2× (-3/7)

so, y= 6/7

Answer:

The slope is [tex]-\frac{4}{3}[/tex]

Step-by-step explanation:

Standard form for a linear equation/graph:

[tex]y = mx + b[/tex]

[tex]m[/tex] is the slope, and [tex]b\\[/tex] is the Y- intercept (basically where the graph crosses the y axis).

[tex]m[/tex] can be shown by a fraction: [tex]\frac{Rise}{Run}[/tex]

In this graph, measuring from the two points of contact, the rise is 4 and the run is -3. If the graph moves towards the left while rising, then the run part of the slope should be negative, and vice versa.

Thus, the slope of this graph is [tex]-\frac{4}{3}[/tex]

Here's the function for the line if you need it:

[tex]y = - \frac{4}{3} x + 3[/tex]
