Answer:
x = 1
Step-by-step explanation:
49=7^x+1
Let's take the log of both sides
(x+1)*(log(7))=log(49)
x + 1 = log (49) / log (7)
x + 1 = 2
subtract 1 from both sides
x = 1

Find the area of the figure
Answer:
89 m²
Step-by-step explanation:
It should be no surprise that the area can be found as the difference between the area of the enclosing rectangle and the area of the triangular cutout.
The rectangle area is given by ...
A = LW
A = (13 m)(8 m) = 104 m²
The base width of the triangular cutout is 13 m - 4 m - 4 m = 5 m. The area of that cutout is given by ...
A = 1/2bh
A = 1/2(5 m)(6 m) = 15 m²
Then the area of the shaded figure is ...
104 m² -15 m² = 89 m²

Which of the following is a degenerate circle?
O A. r?+ y2 = 5
O B. x+y=7
O c. x² + y² = -2
O d. (x - 5)²+(y - 3)2 = 0
the Equation A. r²+ y² = 5 degenerate the circle.
What are the properties of the circle?The circumference, which is the distance around the object, the diameter, which is the length of a circle measured from one end to the other and passing through its center, and the radius, which is equal to half of the diameter, are the three key characteristics.
The general coordinate equation of a circle is:
(x-h)² + (y - k)² = r²
Where,
(h, k) is the center of a circle,
"r" is the radius of the circle.
Only option A, r²+ y² = 5
Satisfies the general equation of the line,
thus, From option A the coordinates of the circle on the plane r-y
is (0, 0) and the radius of the circle will be √5.
From option B, x+y=7
It is the equation of the line.
From option C, x² + y² = -2
The sum of two squares can not be negative so it is not a real equation
From equation D, (x - 5)²+(y - 3)² = 0
The radius of a circle can not be zero otherwise it will become a point.
therefore, the Equation A. r²+ y² = 5 degenerate the circle.

N17.91°W0.9 hoursStep-by-step explanation:
The sum of the initial vector and the final vector needs to be equal to the original vector. If we let B represent the vector taken after discovering the mistake, we must have ...
wrong vector + B = intended vector
B = (intended vector) -(wrong vector)
Since the speed is presumed constant, we can write the vectors in terms of hours, not miles. For calculation purposes it is convenient to use bearings measured clockwise from north. West of north will be negative bearing angles for the purpose here. Of course, south is a bearing of 180°, so angles west of south are farther clockwise, hence added to 180°.
B = 4.5∠-22° -0.5∠202° = 4.87207∠-17.91192° . . . using a suitable calculator
__
a) The new bearing must be N17.91°W
__
b) At the time the error was discovered, the 4.5 hour trip was already 0.5 hours old. Hence the expected additional time is 4.5 -0.5 = 4.0 hours. The actual additional time is 4.872 hours, so the trip will take ...
4.872 -4.0 ≈ 0.9 . . . hours
longer than originally planned.

Comment on coordinates
Bearings are conventionally rendered as a positive angle in the range 0–360°, measured clockwise from north. Alternatively, they are given (as here) as a positive angle in the range 0–90° east or west from north or south.
Occasionally, you will see bearings expressed as an angle in the range 0–45° from the nearest cardinal direction toward the next-nearest cardinal direction. (For example, E19°S instead of 109° or S71°E.)
Compared to angles measured conventionally on a Cartesian plane, CCW from +x, bearing angles are essentially conventional angles subtracted from 90° (and vice versa). As far as angles are concerned, The Cartesian coordinates are the same as map coordinates if you reflect the map across the line y=x.
Calculators that work with vectors work just fine with bearing distances and angles. You just have to remember that the (a, b) rectangular coordinate pair is (N, E) rather than the usual Cartesian plane (E, N). (East being to the right; North being up.)

Answer:
area: 524 cm²perimeter: 124.8 cmStep-by-step explanation:
The rectangle in the middle has a width equal to the radius of the semicircular ends, so (20 cm)/2 = 10 cm.
The semicircular ends, together, make a complete circle of radius 10 cm.
The area is the sum of the areas of the parts:
A = LW = (21 cm)(10 cm) = 210 cm² . . . . . . rectangle area
A = πr² = π(10 cm)² = 100π cm² ≈ 314 cm² . . . . . circle area
The total area is ...
210 cm² +314 cm² = 524 cm² . . . . area of the figure
__
The perimeter of the figure is the sum of the lengths of all of the edges. From the left, working clockwise, we have ...
P = (1/2 circle of diameter 20) + (rectangle top = 21) +(1/2 circle of diameter 20) +(circle radius = 10) +(rectangle bottom = 21) +(circle radius = 10)
The two 1/2 circles add to a whole circle with a circumference of ...
C = πd = (3.14)(20 cm) = 62.8 cm
Then the whole perimeter is ...
P = 62.8 cm + 21 cm + 10 cm + 21 cm + 10 cm = 124.8 cm

Note that we have used 3.14 for pi. If you use a more exact value, your answers will be slightly different.

what is the name of the shape depicted in the graph below
a. limaçon
b. rose
c. cardioid
d. lemniscate
Answer:
Limaçon
Step-by-step explanation:
In geometry, a limaçon or limacon /ˈlɪməsɒn/, also known as a limaçon of Pascal, is defined as a roulette formed by the path of a point fixed to a circle when that circle rolls around the outside of a circle of equal radius.
The name of the shape depicted in the graph below is a. Limacon.
What are Polar Curves?Polar curves are the curves which are formed using the polar coordinate system.
The distance of the points from the origin will be varying depending on the angle from the positive X axis.
The given curves in the option Limacon, Rose, Cardioid, Lemniscate are types of polar curves.
Limacon is the curve which is also known as Pascal's snail. It is formed by following the path by a fixed point to a circle when this circle rolls another circle's of equal radius outside.
The given shape is the limacon with inner loop.
Lemniscate will always be a 8 shaped curve.
Hence the correct option is a, limacon.
