The surface area of the regular pyramid in the diagram is 189 units². The correct option is C. 189 units²

From the question, we are to calculate the surface area of the regular pyramid

The surface area of the pyramid = Sum of area of the triangular faces + Area of the square base

∴ Surface area of the pyramid = [tex]4(\frac{1}{2}bh)+ b^{2}[/tex]

Surface area of the pyramid = 2bh + b²

Where b is the base

and h is the perpendicular height of each triangular faces

In the given diagram,

b = 7

h = 10

∴ Surface area of the pyramid = 2×7×10 + 7²

Surface area of the pyramid =  140 + 49

Surface area of the pyramid = 189 units²

Hence, the surface area of the regular pyramid in the diagram is 189 units². The correct option is C. 189 units²

Answer:

The inverse of g(x) is [tex]g^{-1}(x)=\frac{2x}{1-x}[/tex]

The domain of g(x) is (-∞,-2)U(-2,∞)

The domain of f(x) is (-∞,-1)U(-1,1)U(1,∞)

Step-by-step explanation:

Find the inverse of g(x).

[tex]y=\frac{x}{x+2}[/tex]

Solve for x

[tex]x=y(x+2)[/tex]

[tex]x=xy+2y[/tex]

[tex]x(1-y)=2y[/tex]

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

[tex]g^{-1}(x)=\frac{2x}{1-x}[/tex]

Find the domain of g(x)

[tex]g(x)=\frac{x}{x+2}[/tex]

Numerator and denominator have domain

(-∞,∞).

However, g(x) is undefined if the denominator is 0.  Hence, x=-2 must be taken out of the domain. So, the domain of g(x) is

(-∞,-2)U(-2,∞).

Find the domain of f(x)

[tex]f(x)=\frac{1}{x^{2} -1}[/tex]

The numerator and denominator have the domain

(-∞,∞)

However, f(x) is undefined if the denominator is 0.  This rules out +1 and -1. So, the domain of f(x) is

(-∞,-1)U(-1,1)U(1,∞)

a) The new quadrilateral points are

S¹(5 ,-4) ,T¹(4,-1), U¹(1,0), V¹( 3 ,-3)

Step-by-step explanation:

Explanation:-

Malik draws quadrilateral STUV in the coordinate plane with vertices at $(-5, -4), T-4-1). U(-1,0) , V(-3,-3)

Malik reflects quadrilateral STUV across the y-axis then the transformed to

( x, y) → (-x ,y)

a) S(-5,-4)→S¹(-(-5) , -4)

S((-5,-4)→S¹(5 ,-4)

b) T(-4,-1)→ T¹(-(-4) ,-1)

   T(-4,-1)→ T¹(4,-1)

c) U(-1,0) → U¹(-(-1),0)

  U(-1,0) → U¹(1,0)

d) V(-3,-3)→ V¹( -(-3) ,-3)

   V(-3,-3)→ V¹( 3 ,-3)

final answer:-

The new quadrilateral points are

S¹(5 ,-4) ,T¹(4,-1), U¹(1,0), V¹( 3 ,-3)

================================================================

Explanation:

There are 13 diamonds out of 52 total.

The probability of getting a diamond card is 13/52.

After selecting that diamond card and not putting it back, we have 13-1 = 12 diamonds left out of 52-1 = 51 left. The probability of getting another diamond is 12/51.

Then the probability of getting a third diamond is 11/50, and finally 10/49 represents the probability of getting a fourth diamond. Each time we need a new probability, we just subtract 1 from the numerator and denominator.

The numerators are: 13, 12, 11, 10

The denominators are: 52, 51, 50, 49

We'll multiply the four fractions to get our final answer

(13/52)*(12/51)*(11/50)*(10/49) = 0.00264105642257

This rounds to 0.0026 which is roughly a 0.26% chance

The answer as an exact fraction is 11/4165

The scale of the map is inch = 20 feet.

This statement must be incorrect or the fraction of the inch is missing.

Because 6" long, at a scale of one inch = 20 feet, would only be 120 feet x 120 feet.

120 x 120 = 14,000 ft^2 and each of the four quadrants wouls only be 3600 ft^2.
