a point in rectangular coordinates is given. Convert the point to polar coordinates. Round your answers to two decimal places.
(5,7)
Answer:
(√74, 54.46°)
Step-by-step explanation:
The rectangular coordinate point is given as; (5, 7)
Now, converting rectangular coordinates to polar coordinates is done by;
(r, θ)
Where, r is the magnitude while θ is the angle
r = √(5² + 7²)
r = √74
tan θ = (7/5)
θ = tan^(-1) 1.4
θ = 54.46°
Thus,polar coordinate is; (√74, 54.46°)

In circle D, angle ADC measures (7x + 2)°. Arc AC
measures (8x - 8)º.
What is the measure of angel ABC
Answer:
The measure of angle ABC is 36° ⇒ 1st answer
Step-by-step explanation:
Let us revise some important facts in the circle
The measure of the center angle is equal to the measure of its subtended arc
The measure of the inscribed angle is equal to half the measure of the central angle subtended by the same arc
The vertex of a central angle is the center of the circle and its sides are radii in the circle
The vertex of an inscribed angle is a point on the circle, and its sides are chords in the circle
In circle D
∵ D is the center of the circle
∵ A and C lie on the circle
- DA and DC are radii
∴ ∠ADC is a central angle subtended by arc AC
∴ m∠ADC = m of arc AC
∵ m∠ADC = (7x + 2)°
∵ m of arc AC = (8x - 8)°
- Equate them to find x
∴ 8x - 8 = 7x + 2
- subtract 7x from both sides
∴ x - 8 = 2
- Add 8 to both sides
∴ x = 10
Substitute the value of x in the measure of ∠ADC
∵ m∠ADC = 7(10) + 2 = 70 + 2
∴ m∠ADC = 72°
∵ AB and BC are two chords in circle D
∴ ∠ABC is an inscribed angle subtended by arc AC
∵ ∠ADC is a central angle subtended by arc AC
- By using the 2nd fact above
∴ m∠ABC = m∠ADC
∴ m∠ABC = × 72
∴ m∠ABC = 36°
The measure of angle ABC is 36 degrees
Circle geometry
To get the required measure of m<ABC, we will use the theorem that states that the measure of the central angle is equal to the measure of its subtended arc and;
The vertex of a central angle is the center of the circle and its sides are radii in the circle
According to the given circle D
∠ADC is a central angle subtended by arc AC
m∠ADC = m of arc AC
m∠ADC = (7x + 2)°
m of arc AC = (8x - 8)°
Equate to find the value of x
8x - 8 = 7x + 2
x - 8 = 2
x = 10
Substitute the value of x in the measure of ∠ADC
m∠ADC = 7(10) + 2 = 70 + 2
m∠ADC = 72°
∠ADC is a central angle subtended by arc AC
m∠ABC = 0.5 × 72
m∠ABC = 36°
Hence the measure of angle ABC is 36 degrees

Express the lcm of 50,18 and 32 in prime factors
Answer:
The least common multiple of 50, 18 and 32 is 7200.
Step-by-step explanation:
mark brainleist plz
Answer:
LCM = 7200
Step-by-step explanation:
LCM(18, 32, 50) =
LCM(LCM(18, 32), 50)
Working from the innermost parentheses outward:
LCM(18,32) = (18 × 32) / GCF(18,32)
= (18 × 32) / 2
= 576 / 2
= 288
LCM(288,50) = (288 × 50) / GCF(288,50)
= (288 × 50) / 2
= 14400 / 2
= 7200
Therefore,
LCM(18, 32, 50) = 7200

Answer:
Mean: 22
Median: 25.2
Step-by-step explanation:
The mean is the sum of all the numbers in a set divided by the number of terms in a set.
The median is the middle value of the numbers when the numbers in a set are arranged from least to greatest. If there is two middle numbers, the median is the average of the two numbers.

Answer:
18.84 units
Step-by-step explanation:
The question is incomplete, however, we can proceed with the given information
Given data
The expression for the circumference of a circle is given as
C= 2πr
Hence when we have a value for the radius say r= 3
Hence the circumference can be found as
C= 2*3.14*3
C= 18.84 units
