What is the area of the regular polygon shown below?
A function and its inverse are shown on the graph. Which statement describes the relationship between the function and its inverse? The range of both f(x) and f–1(x) is all real numbers. The domain of both f(x) and f–1(x) is all real numbers. The range of f(x) is y > 0 and the domain of f–1(x) is x > 0. The domain of f(x) is x > 0 and the range of f–1(x) is y > 0.
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.

29 Answer:
Solve: 18.3% of 74 = n n = _____
30 Answer:
Solve: 6.5% of 115 = n n = _____
31 Answer:
Solve: 0.75% of 93 = n n = _____
Step-by-step explanation:
13.
132 miles in 3 h = 132miles/3hours = 132/3 miles/h =
= 44 miles/h
so,
how long for 110 miles ?
speed = distance/time
time = distance/speed = 110 miles / 44 miles/h =
= 110/44 h = 55/22 h =
= 5/2 h = 2.5 h
14.
60% = 60/100 = 6/10 = 3/5
15.
300% = 300/100 = 3
16.
116 2/3% = (348 + 2)/3% = 350/3% = 350/3/100 =
= 350/300 = 1 50/300 = 1 1/6
17.
19% = 19/100
18.
3.8% = 3.8/100 = 38/1000 = 19/500
19.
166 2/3% = (498 + 2)/3% = 500/3% = 500/3/100 =
= 500/300 = 5/3 = 1 2/3
20.
4/5 = 0.8 = 80%
21.
7/4 = 1.75 = 175%
22.
1/3 = 0.3333333... ≈ 33.33%
23.
2 = 200/100 = 200%
24.
0.4 = 40%
25.
0.375 = 37.5/100 = 37.5%
26.
80% of 60 = 60×80/100 = 60×4/5 = 48
27.
24% of 65 = 65×24/100 = 65×6/25 = 13×6/5 =
= 15.6
28.
115% of 138 = 138×115/100 = 138×23/20 =
= 69×23/10 = 158.7
29.
18.3% of 74 = 74×18.3/100 = 74×183/1000 =
= 37×183/500 = 13.542 ≈ 13.54
30.
6.5% of 115 = 115×6.5/100 = 115×65/1000 =
= 23×13/40 = 7.475 ≈ 7.48
31.
0.75% of 93 = 93×0.75/100 = 93×75/10000 =
= 93×3/400 = 0.6975 ≈ 0.70

A triangle has sides with lengths of 10 millimeters, 25 millimeters, and 28 millimeters, is it a right triangle
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.
Kathleen says that all quadrilaterals have right angles. Grace says that quadrilaterals do not have to have right angles. Explain who is correct.
Answer: Grace is correct because a rhombus does not have right angles
Step-by-step explanation:
Grace's assertion is on point. Right angles are not present in all quadrilaterals.
What is quadrilateral?A quadrilateral in geometry is a four-sided polygon with four edges and four corners.
As per the definition of Quadrilateral and rectangle, the rectangle is the type of quadrilateral that has 4 right angles.
Other varieties of quadrilaterals consist of:
Trapezium: Doesn't must have four right angles, but has one pair of opposite sides that are parallel.
A parallelogram has four right angles, but not necessarily two sets of opposite sides that are parallel.
All four sides of a rhombus are equal in length, although there aren't always four right angles.
Kite: Does not must have four right angles, but two adjacent pairs of sides that are equal in length.
Therefore, Grace's assertion is right.

A. 0.22

C. 0.165
D. 0.275
Answer: C. 0.165
Step-by-step explanation:
The value of P(A∪B) = 0.835
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
Given that, A and B are dependent events. If P(AIB) = 0.55 and P(B) = 0.3,
0.55 = P(A∩B) / 0.3
P(A∩B) = 0.165
P(A) = 1-P(B)
P(A) = 1-0.3
P(A) - 0.7
P(A∪B) = P(A) + P(B) - P(A∩B)
P(A∪B) = 0.3+0.7-0.165
P(A∪B) = 0.835
Hence, the value of P(A∪B) = 0.835

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

What is the slope of the line?
m=
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]

Answer:
Rinzin is older
Step-by-step explanation:
The reason is that since you probably already know that there are 12 months in a year it would be 85/12=7.0833 years and 23/12=7.666 so that makes rinzin older
Hope that helps :)

What is Equation?Two or more expressions with an Equal sign is called as Equation.
Pema is 85 months old and
Rinzin is 7⅔ years old.
We have to check who is older.
We know that 1 year = 12 months
So if 85 months are conveted to years by dividing 85 by 12
Pema, 85/12 years= 7.08 years
Rinzin, 7⅔ years = 7.06 years
We know that 7.08>7.06

If you deposit $25,000 now at 6.5% compounded quarterly, how much will you have in 30 years?
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]
