Answer:
Vertical intercepts: (-2,pi/2) and (-10,pi/2)
Horizontal intercepts: (4,0) and (-4,0)
Step-by-step explanation:
I took the test and got it right.
The required horizontal intercepts are at approximately (41.81°, 0) and (138.19°, 0), and the vertical intercepts are at (0, 4) and (0, -10).
What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
To find the horizontal intercept(s) of the limacon, we need to set r equal to zero and solve for theta.
r = 4 - 6sin(Ф)
0 = 4 - 6sin(Ф)
6sin(Ф) = 4
sin(Ф) = 4/6
sin(Ф) = 2/3
We can use an inverse sine function to find the value of theta:
Ф= sin^-1(2/3)
Ф≈ 41.81° or 138.19°
These are the values of theta where the limacon crosses the x-axis (horizontal intercepts).
To find the vertical intercept(s), we need to set theta equal to zero or pi and solve for r.
When Ф= 0:
r = 4 - 6sin(0)
r = 4
So the limacon intercepts the y-axis at (0, 4).
When Ф= pi:
r = 4 - 6sin(pi)
r = 10
So the limacon intercepts the y-axis at (0, -10).
Therefore, the horizontal intercepts are at approximately (41.81°, 0) and (138.19°, 0), and the vertical intercepts are at (0, 4) and (0, -10).

Answer:
Subtract 8 from both sides of the inequality. Divide both sides of the inequality by 3.
Step-by-step explain
The given inequality is 3b + 8 ≥ 14
We need to solve the given inequality
Step 1.
Subtract 8 to the both sides of the inequality
3b + 8 - 8 ≥ 14 -8
3b ≥ 6
Dividing both sides by 3

Jim rented a truck for one day. There was
base fee of $17.95, and there was an additional charge of 87 cents for each mile driven, Jim had to pay $153.67
when he returned the truck. For how many miles did he drive the truck?
Answer:
Jim drove the truck 156 miles
Step-by-step explanation:
Represent the number of miles driven with x.
Then the formula for the total rental cost is C(x) = $17.95 + ($0.87/mile)x, and this comes to $153.67. Solve for x:
$153.67 - $17.95 = ($0.87/mile)x, or
$135.72 = ($0.87/mile)x
Dividing both sides by ($0.87/mile), we get:
x = 156
Jim drove the truck 156 miles

Answer:
4
Step-by-step explanation:
9+3=12
12x1/2=24
24/6=4
h=4
Height of trapezoid is,
⇒ h = 4 km
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The area of the trapezoid is 24 Square km.
We know that;
Area of Trapezoid = (a + b) h / 2
Here, A = 24 km² , a = 3 km , b = 9 km
Hence, We get;
24 = (3 + 9) h / 2
48 = 12h
h = 48 / 12
h = 4 km
Thus, Height of trapezoid is,
⇒ h = 4 km

A new car is purchased for $26,000 and over time its value depreciates by one half every 5 years. What is the value of the car years after it was purchased to the nearest hundred dollars?
Answer: $6,500
Step-by-step explanation:
Question says after 10 years.
The value of the car depreciates by 1/2 every year which is 50%, every 5 years.
In 10 years therefore, the car would have depreciated by half of its value, twice.
Use the future value formula:
= Amount * (1 + rate) ^ no. of periods
= 26,000 * ( 1 - 50%)²
= $6,500
Note: There are two periods because the depreciation is every 5 years and 10 years have gone by so the number of periods is: 10 / 5 = 2 periods

Since triangle 2 is a right triangle, write an equation applying the Pythagorean Theorem to the triangle.
Answer: a^+b^2=n^2
Step-by-step explanation:
The equation for triangle 2 will be: a² + b² = n².
What is Pythagorean theorem?
Pythagorean theorem states that for a right-angle triangle, the sum of the squares of the base and the height is equal to the square of the hypotenuse of that triangle.
Here, the angle between side: a and side: b is a right-angle.
Therefore, we can consider side: a as the height and side: b as the base of the triangle.
Therefore we can write as per the Pythagorean theorem:
(Base)² + (Height)² = (Hypotenuse)²
Hence, a² + b² = n²
