This table of values represents a linear function.
Enter the rate of change of this function.
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°)

Place Temperature (° Fahrenheit) Death Valley, CA 134 Barrow, AK negative 53 Question What is the difference of the temperatures in the table? Answer options with 4 options A. 71 ° Fahrenheit B. 81 ° Fahrenheit C. 87 ° Fahrenheit D. 187 ° Fahrenheit
Answer:
D: 187 °F
Step-by-step explanation:
You need to subtract -53 from 134. But since that 53 degrees is negative and you are subtracting it, you change the negative sign to a positive sign and add positive 53 to positive 134 to get 187.
A pet store has two tanks of tropical fish. The first tank contains 5 blue fish and 2 yellow fish and the second tank contains 7 blue fish and 2 yellow fish. If Keisha randomly purchases a fish from each tank, what is the probability that both fish will be blue?

Step-by-step explanation:
First of all it should be like fractions
So -2/3 becomes -10/15
and -3/5 becomes -9/15
-9/15 is greater than -10/15
-3/5 is greater than -2/3
Answer:
-2/3 < -3/5
Explanation:
to convert the fractions to equivalent forms, we need to make sure that they have the same denominator (number on the bottom). the lowest common multiple of both 3 and 5 is 15, hence:
-2/3 = -10/15 (×5)
-3/5 = -9/15 (×3)
thus, we can see that -10/15 is smaller than -9/15, and -2/3 is smaller than -3/5.

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

Determine the value of y in the figure below.
need help i don’t know what the answer is
Answer:
r = 5
Step-by-step explanation:
(r + 8)^2 = r^2 + 12^2
r^2 + 16r + 64 = r^2 + 144
16r = 80
r = 5
Answer:
r = 5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle ABC
AC² = BC² + AB²
(r + 8)² = r² + 12² ← expand left side using FOIL
r² + 16r + 64 = r² + 144 ( subtract r² from both sides )
16r + 64 = 144 ( subtract 64 from both sides )
16r = 80 ( divide both sides by 16 )
r = 5
Determine the value of the variable that makes the equation true. 12-b=12.5
Answer:
B = -.5
Step-by-step explanation:
If B is negative is cancels out the prexisting negative making it positive.
Are the given values in the table enough information to show an exponential function instead of a linear function? If not, explain why not then write the equations for both an exponential and linear function represented by the table.
